Unfortunately, the Acromantulas, which struck fear into the hearts of wizards, encountered Goku today.
In the face of absolute power, numbers held no meaning.
In terms of physical fitness, the Acromantulas were far inferior to Goku; their venom and webs only managed to hit Goku's afterimages.
Thus, in less than an hour, the dense swarm of Acromantulas all lay prostrate on the ground.
This was even without Goku using techniques like Kamehameha and Dodon Ray.
Because he remembered Hagrid's words, he didn't kill them during the fight; all the Acromantulas were still alive.
"That was a lot of fun. I'll come back to play with you all again tomorrow night."
Clapping his hands, Goku continued deeper into the Forbidden Forest.
After Goku's figure disappeared, an Acromantula, significantly larger than a full-grown elephant, slowly crawled out of a hidden tree hollow.
"Is that guy even human? Not even those wizards could possess such terrifying power."
It was none other than Aragog, the father of this group of Acromantulas and the strongest Acromantula.
But he had no intention of defending his children just now, because he knew that if he dared to show his face, he too would end up on the ground.
At ten o'clock that night, Goku's figure appeared in front of Hagrid's hut, signaling the end of his combat training for the day.
Dumbledore, who had been waiting for a long time, inquired about Goku's experiences in the Forbidden Forest, then remarked with a sigh:
"The magical creatures in the Forbidden Forest can hardly make you exert your full strength. You'll have to make do with this training for now.
After a while, I'll send you to the Hebrides, where a large group of powerful Black Dragons live. They should be able to help you with more effective combat training."
"I feel pretty good about it," Goku replied.
Goku didn't mind, as he had rarely encountered opponents stronger than the Acromantulas during his previous training.
Since he began his training after leaving Fortuneteller Baba, he had only met three masters: Chen Daquan, Tianlong, and Ashura.
His other combat opponents were merely tigers, lions, and dinosaurs in the mountains, whose strength was inferior to the Acromantulas.
If he could fight so many Acromantulas every day, it would still be very helpful for improving his strength.
"Goku, can you teach Hagrid how to use ki?"
Dumbledore beckoned Hagrid over, and Goku nodded, beginning to instruct Hagrid on how to condense ki within his body, following Master Roshi Grandpa's guidance from back then.
During the year he trained with Master Roshi Grandpa, Master Roshi Grandpa didn't teach them any specific techniques.
However, in their cultural lessons, he provided detailed guidance on the condensation and utilization techniques of ki within the body.
Otherwise, solely through high-intensity physical training, he and Krillin wouldn't have achieved such a significant increase in strength in just one year.
Only by understanding how to utilize ki in conjunction with the body can one truly unleash power and speed that surpasses human limits.
It was precisely because he learned about ki from Master Roshi Grandpa that he was able to unleash a Kamehameha comparable to Master Roshi Grandpa's.
It wasn't like his initial attempts at mere imitation, which could at most overturn a car.
"ki is a power that every one of us possesses within our bodies; it's not just humans, but all things in the world contain ki.
The stronger the body, the easier it is to perceive the existence of ki.
After that, one must learn to control ki. Only by being able to control ki can we utilize it to strengthen our bodies for combat…"
Goku sat cross-legged on the ground, repeating what Master Roshi Grandpa had said, then slowly brought his palms together, guiding the ki within his body to condense into his palms.
A moment later, a faint ball of ki slowly appeared in Goku's palm.
"Look, this is ki!"
"This is ki!"
Hagrid, whose head was almost as big as Goku's entire body, leaned in, looking at the small ball of ki with a face full of curiosity.
Dumbledore also bent down; he was equally curious about this power, which was no less potent than the forces of this world.
"It is indeed different from magic," Dumbledore mused, sensing the ball of ki.
When Goku used Qigong Wave before, the fluctuations of ki were too explosive to perceive in detail.
Now that Goku had gently drawn out the ki from his body, he had made some new discoveries.
A wizard's magic primarily comes from their wizarding bloodline, a power generated by the combination of a wizard's physical bloodline and spirit.
However, the energy of ki, in his perception, was primarily divided into three parts.
One part also came from the body, but unlike a wizard's power from their bloodline, this was purely the power of the physical body, or more precisely, the power of life.
Another part came from the spirit; meditation and guidance of the mind involved integrating one's spiritual power into the life force.
The third part came from the natural world outside, which their wizarding magic did not possess.
A wizard's magic resides solely within the body, with no external forces involved.
Therefore, ki, composed of three forces, had much greater power than magic, composed of two forces, at the same volume.
A wizard's pure magical output was not inherently destructive; it required magic to alter the form of magic, thereby producing various effects.
But ki was different; simply releasing it possessed strong destructive power, and if condensed, compressed, and then exploded, its destructive power was even more terrifying.
In his opinion, Goku's Dodon Ray and Kamehameha actually didn't have much technical content; they were simply explosions achieved by condensing and compressing ki.
Therefore, ki, composed of three energies, could easily replace magic, composed of two energies, to cast magic.
However, if one wanted to condense and compress magic to release Dodon Ray and Kamehameha, it would be quite unrealistic.
Even if released, the power would be greatly diminished.
Therefore, the previous idea of using a clever method—first using magic to replace ki to release Goku's techniques—
to allow wizards to master a wandless attack ability, could now be abandoned.
One still needed to train the body to its limit and possess ki to truly master the Turtle School's fighting style.
Moreover, once one possessed ki, even if not particularly skilled in magic, one could still cast spells wandlessly like Goku.
"Keep it up, Hagrid. The future peace of the Wizarding World might just depend on you!"
Dumbledore looked at Hagrid, who was earnestly learning how to control the ki within his body from Goku, and murmured to himself.
After half an hour of instruction, and many demonstrations by Goku, Hagrid still hadn't learned how to control ki.
But it wasn't without any progress; at least he seemed to gradually feel the presence of ki within his body.
However, to control it like Goku would require more time for practice.
Fortunately, Hagrid's mind was relatively simple, which actually gave him an advantage over typical wizards in this regard.
In return, before Dumbledore sent Goku back to his dormitory to sleep, Hagrid made rock cakes and homemade roasted sausages again.
Although the rock cakes were still hard and tooth-breaking, and half of the sausages were burnt.
However, Goku was clearly not that picky; he was already very happy to have food, which perfectly replenished the stamina he had expended fighting in the Forbidden Forest.
Thus, every day—extreme training in the morning, Charms in the late morning, theory in the afternoon, and the Forbidden Forest in the evening—continued until Saturday.
This day was when Goku, as the ki magic Professor, was scheduled to begin his classes.
At six in the morning, the little wizards, who were supposed to be sleeping in on Saturday, all woke up early today.
Because today was the day ki magic classes were scheduled to begin.
Although five days had passed, everyone's excitement about Goku defeating two Professors and challenging Dumbledore remained high.
After Goku challenged Dumbledore, Hogwarts suddenly added a new magic course, and it was even scheduled for Saturday, which was originally a day off.
This was simply too abnormal.
Students of all grades could sign up for the course, and it was voluntary to join or withdraw, which further highlighted its uniqueness.
The teacher for this course was a twelve-year-old child, which was unprecedented.
Coupled with the fact that Goku, the central figure of the events, had not appeared at school for these five days, everyone's curiosity about Goku and this course reached its peak.
So, early this morning, whether they had signed up or not, all the little wizards woke up early and waited on the lawn outside the castle gate.
Indeed, according to the notice, the teaching of ki magic was not in a classroom within Hogwarts Castle, but on the lawn outside the castle gate.
Seven to eight hundred little wizards, from first to seventh grade, stood densely on the lawn.
They whispered to each other, discussing questions related to ki magic.
Among them were Harry, Ron, and Hermione, the three little wizards who were familiar with Goku.
"It's really strange, doesn't this class have a textbook?"
Hermione complained, feeling a bit unaccustomed.
Without a textbook, she couldn't preview; without previewing, she wouldn't be able to raise her hand to answer questions in class later, and thus wouldn't be able to score points.
Even the Advanced Care of Magical Creatures class had a textbook.
Ron yawned widely and retorted:
"You can't do without previewing a textbook, can you?
That's why I signed up for this class, even if it's on a Saturday and I have to wake up so early!"
He had been deeply frustrated by taking classes with Hermione this week.
As a child from a Wizarding family, his brothers were all the most outstanding Wizards in their grades, yet he had such a huge gap with Hermione, who was from a muggle background.
He didn't have the same sense of superiority about his background as the Slytherin Wizards, nor did he discriminate against muggle-born Wizards.
But he felt he should have some advantage, yet he was completely crushed.
Crucially, Hermione always lectured him on his studies in a condescending tone, which made him feel very hurt in his self-esteem.
Therefore, he was very happy to see Hermione look deflated.
Hermione, without a preview textbook, wouldn't necessarily perform better than him in class.
"Hmph, even without previewing, I'll still learn faster than you!"
Hermione gave Ron a look of royal disdain, and Ron shivered with anger but could do nothing.
"Look, it's Goku… and all the Professors are here!"
At this moment, Harry suddenly exclaimed, interrupting their bickering.
At the castle gate, Headmaster Dumbledore and Goku walked side by side at the very front, followed closely by the four Deans and Professors of other courses.
A new course, attracting all the teachers of the school, made the little wizards even more excited.
Actually, Dumbledore hadn't ordered all the teachers to come.
Originally, it was just him, Goku, and Madam Pomfrey, who was responsible for immediate treatment.
However, not only were the little wizards curious, but the school's Professors were also curious about the content of the ki magic course.
Aside from Snape and McGonagall, who knew a little, the other Professors weren't very clear why the Headmaster attached so much importance to this course.
"Quiet!"
Dumbledore's voice, amplified by the Sonorus Charm, rang out across the lawn, and the noisy little wizards immediately fell silent.
"The ki magic you are about to learn is a very powerful magic.
And Professor Sun, who will teach you this magic, is a powerful Wizard whose strength is not inferior to mine."
Upon hearing Dumbledore say this, all the little wizards and some of the Professors showed expressions of disbelief.
Strength not inferior to Dumbledore—even Voldemort, everyone felt that in terms of true strength, he was not as powerful as Dumbledore.
How could a twelve-year-old Professor Sun's strength compare to Dumbledore's, even if he defeated two Deans?
Most people felt that Dumbledore saying this was probably just being humble.
Dumbledore ignored the Little Wizards' whispers and continued:
"But I also want to tell you that learning ki magic is very difficult, more difficult than any course you have ever taken.
Only the smartest, bravest, most talented, and most persevering Wizards will be able to learn this course.
So if you feel you are not capable, if you feel you are a waste, if you feel you are a person without dignity,
you can choose to give up this course at any time.
However, I believe that you are all the most talented Wizards in this world, and you will definitely persevere!"
Hearing Dumbledore's words, all the little wizards who had signed up for the course proudly puffed out their chests.
Even the Slytherin little wizards were like this at the moment.
They considered themselves the noblest Wizards in the Wizarding World, how could they be willing to be outdone by Wizards from other houses?
And those Wizards who had not signed up for the course secretly felt some regret and planned to sign up after watching today's class.
Although the ki magic course aroused everyone's curiosity, many older little wizards were preparing for the Ordinary Wizarding Level exams and the Nastily Exhausting Wizarding Test.
And Wizards who were about to graduate were also making plans for their future development after graduation.
So most of the fifth, sixth, and seventh-year little wizards were very pressed for time.
Wasting a day to learn a new course was clearly not wise.
Even though the magic of this course was powerful, most Wizards did not plan to become Aurors after graduation.
More than ninety percent of Wizards, in the jobs they pursued after graduation, did not involve combat.
More often, it was the application of certain related magic knowledge.
For example, if you are good at Herbology, you can work in a herb shop, or simply open one.
If you are good at cooking magic, you can apply for a job in a pub, or open a pub.
If you are good at curse-breaking, you can work as a curse-breaker at Gringotts.
Even if you join the Ministry of Magic, as long as you are not an Auror, a clerical worker does not need to participate in combat.
It's like when you are about to graduate from university, and suddenly there's a martial arts class that, if you learn it, will enable you to fight several people.
Under urgent circumstances, you wouldn't learn it, because it doesn't help much with your employment.
Scanning around and taking in the expressions of all the little wizards, Dumbledore knew his goal had been achieved, so he stepped aside.
"Goku, you can begin."
At this moment, Goku, following Dumbledore's pre-arranged teaching steps, walked to the front of all the little wizards, successfully attracting all attention.
He didn't speak, but instead assumed the starting stance of Kamehameha and began to gather the ki within his body.
"Kamehameha!!!"
With a roar, Goku aimed his Kamehameha at a three to four hundred-meter high mountain across the Black Lake, below the lawn.
"Boom!"
The terrifying boom instantly gave the Professor and little wizards the illusion that their ears were going deaf.
After the boom, a wave of air rushed towards them, so powerful that some of the weaker little wizards almost lost their footing.
Once the dust settled, all the Professor and little wizards looked at the three to four hundred-meter-tall mountain again, their eyes filled with horror.
The mountain had completely vanished from their sight, as if it had never existed.
"This is my ki magic. If I can do it, so can you!"
Under Dumbledore's Sonorus Charm, Goku's voice echoed throughout the venue, pulling the Professor and little wizards back from their daze.
"Too powerful! Too powerful!"
The little wizards' faces were all filled with excitement. They had to learn it, no matter what, they had to learn ki magic.
If learning a martial art only allowed you to defeat a few people, you might not be that interested.
But if learning a martial art allowed you to fight against ten thousand, or even a hundred thousand, then surely few people could refuse.
The little wizards nearby who hadn't signed up wished they could sign up for this course right away.
"I hope it has some effect!"
Seeing this, Dumbledore murmured to himself.
He had gone through all these pre-class antics to maximize the little wizards' love for ki magic.
Otherwise, he worried that after today's class, not a single little wizard would be willing to continue learning this course.
Although Hagrid had already set a precedent, he still hoped that more wizards would learn ki magic.
Voldemort had so many powerful Death Eater helpers, and Hagrid would also need many masters of ki in the future.
"All registered students, step forward. First, hand over your wands and place them aside, then line up in rows according to your year and house."
At Goku's command, the registered little wizards immediately formed four squares, seven rows in each.
Fewer older little wizards signed up, but there were some; these were the little wizards who planned to interview for Auror positions after graduation.
Last night, Dumbledore had already gone over the entire teaching plan for today's course with him.
As long as he followed the steps, there wouldn't be any major problems.
He actually found this quite interesting.
Because it allowed him to recall the wonderful time he spent training with Grandpa Master Roshi, and it wouldn't delay his own training.
"Flashtwist!"
Dumbledore secretly waved his wand, and boxes containing milk bottles appeared in front of all the little wizards.
The boxes for older wizards were heavier, while those for younger ones were lighter.
"What is this for?"
The little wizards looked at the milk boxes that appeared at their feet, their faces filled with great confusion.
"Before the official class starts, we'll have a warm-up. Everyone, carry a milk box and run a lap around the Black Lake.
After running, eat breakfast, and after breakfast, the official class will begin."
Goku said, then slung the log Hagrid had prepared for him last night onto his back.
He said it was a warm-up for the little wizards, but it was also a warm-up for his own training today.
"What, carry this milk box and run a lap around the Black Lake? You're not joking, are you!"
Upon hearing this, the little wizards all looked astonished.
The Black Lake was over ten miles long in circumference; even without carrying anything, they couldn't finish a lap, let alone carrying heavy milk boxes.
This was simply a joke.
"Start running!"
Goku shouldered the heavy log and took the lead.
Seeing this, although the little wizards found it hard to understand, they remembered what Dumbledore had said earlier and gritted their teeth to follow.
Fortunately, Goku's speed wasn't fast, and everyone could barely keep up.
At this moment, Madam Pomfrey, carrying a prepared first-aid kit, also followed on her broomstick. She had to be ready to treat injured little wizards at any time.
Watching Madam Pomfrey follow behind, the little wizards who were running with milk boxes gradually felt something was amiss.
They were just running; why was Madam Pomfrey following?
Although carrying a milk box and running a lap around the Black Lake was a very difficult task, at worst, they could run slower, and if they got tired, they could rest and then continue.
In any case, they would eventually complete it.
And soon, they found out why Madam Pomfrey was following.
"Huh, when did these hills appear here?"
As they ran, the little wizards noticed a series of ten-meter-high hills appearing ahead, with very steep inclines and declines.
A slight slip could send them tumbling down the hill with their milk boxes.
Given the little wizards' physiques, it wasn't a major issue, but pain was certainly unavoidable.
Moreover, these hills greatly increased the difficulty of their run, and they quickly became breathless.
After much effort, they passed through the hills, only to find a series of large pits ahead, ten meters deep, with only four logs, each wide enough for one person, spanning the pits.
The little wizards had to carefully cross the large pits by stepping on the logs while carrying their milk boxes.
If they fell, they wouldn't die, but a broken bone was inevitable.
At this point, Madam Pomfrey's role became prominent.
Upon discovering a little wizard who had fallen into a pit, Madam Pomfrey would ride her broomstick over to rescue them, then heal them with healing magic and potions.
And after being healed?
Naturally, they had to continue advancing with the group.
"Pay attention to your balance! Pay attention to your balance!"
Goku, carrying a heavy log, jumped back and forth over the large pits.
Just as Grandpa Master Roshi guided him and Krillin in their training, he taught these little wizards the techniques of training.
Occasionally, he also helped Madam Pomfrey, who was overwhelmed, by rescuing little wizards who had fallen into the pits.
Finally, after almost half of the little wizards had experienced broken bones, they crossed the pit area.
However, was that the end?
Of course not. After the pit area was a desert area; for some reason, a two-mile stretch had completely turned into a desert.
They needed to carry their milk and cross the desert to continue forward.
At this moment, many little wizards were gradually breaking down, especially those from well-off families; they had never endured such hardship.
"Professor Sun, I really can't go on. I'm dropping out of this course."
"Professor Sun, we're here to learn ki magic, not to run. I think this method of learning is unreasonable."
"Professor Sun, let us rest for a bit, rest a bit before continuing."
Many little wizards sat in the sand, unwilling to continue forward.
Goku was not surprised by this situation; Dumbledore had already taught him how to handle such situations yesterday.
And he felt that this method of handling was very consistent with the training of the Turtle School.
"Aragog!"
Goku shouted towards the nearby woods, and soon a rustling sound came from deep within the woods.
Not long after, the little wizards saw dense Acromantula, drooling as they rushed towards them.
Under Goku's joyful 'subduing spiders with virtue' every night, these Acromantula had all become Goku's friends.
"Ah!!!"
Screams rose and fell, and the little wizards, who were already exhausted, immediately cried out for their parents and ran across the sand.
Their speed was even faster than when they started on flat ground.
