As Beorn transformed into a giant bear, a wild, primal sense of oppression washed over them.
Even knowing the giant bear in front of him was Beorn, there was still an urge to retreat.
"Beorn, don't resist later. Can I examine the magic circulation within your body?"
The giant bear nodded, signaling for him to proceed.
Seeing Beorn agree, Luke immediately placed his hand on the giant bear's skin and slowly injected magic into it to sense how the magic operated within the giant bear.
The reason Animagi cannot transform into magical creatures is due to the fundamental difference in how Wizard magic and magical creature magic operate.
And once this method of magic operation is forcibly broken, it can easily lead to severe and unpredictable consequences.
For example, the Quintaped in the magic world is said to have been transformed from a Wizard.
But because the magic operation method within the body changed during the transformation, once they became a Quintaped, they could never change back, thus adding a new creature to the magic world.
In the magic world, very few Wizards practice Animagus, and even fewer succeed.
There were only seven registered Animagi in the entire 20th century, and even if those who secretly practiced without registering were added, there weren't many in total.
There were no successful precedents of transforming into magical creatures, coupled with the severe consequences brought by those who did transform into magical creatures.
Therefore, Wizards in the magic world never dared to easily attempt Animagus transformations into magical animals.
However, it was different for Luke.
Although Beorn was a skin-changer, his ability to transform into a giant bear was an excellent reference.
If he could unravel the mystery of Beorn's transformation and integrate it into his own Animagus, he might be able to possess a stronger Animagus.
Luke very carefully sensed the magic operation within the giant bear, feeling the difference between its magic circulation and his own.
Beorn also had magic within his body, and it was not low.
This was also the reason he could transform into a giant bear.
However, as Luke continued to perceive the magic operation system within the giant bear, his expression became increasingly solemn, and he finally sighed and withdrew his hand.
"Thank you, Beorn, you can change back now."
The giant bear let out a low growl, its massive body rapidly shrinking, eventually transforming back into human form.
Beorn put his clothes back on and asked, "Did you gain anything?"
Luke nodded: "I gained a lot. Your magic circulation method is very unique. If I could fully replicate it, perhaps I could unravel the mystery of the skin-changer's transformation."
"It's just that your magic circulation system is too complex. To record it all would probably be a huge undertaking, requiring at least several years or even longer!"
magic circulation is similar to the circulation of true qi in meridians in Wuxia novels, forming a complete and complex magic circulation system within the body.
However, the magic circulation and operation of Wizards are not the same as those of magical creatures.
If a Wizard forcibly transforms into a magical creature, the magic circulation within their body will be broken.
At best, magic loses balance and becomes chaotic, turning them into a Squib.
At worst, they permanently become a magical creature, with their soul trapped within the beast's body, even worse than a Blood-Curse Beastman!
After all, it is impossible for two magic circulation systems to coexist within one person's body.
However, Beorn was different.
Luke discovered that he had one type of magic circulation when in human form, but another type of magic circulation system when transforming into a giant bear.
Beorn could freely switch between these two systems, allowing him to change back and forth between human and giant bear forms.
If he could find the switching point between the two, Luke might be able to find a way to make Animagi transform into magical creatures.
But this was still too distant for Luke at the moment.
Just recording Beorn's complex magic circulation system would take a very long time.
And there could be no deviation or omission in between.
Otherwise, it would be a serious magic accident.
To this, Beorn waved his hand very readily and said:
"What's the big deal? If you want to research, you can find me anytime, even stay here permanently. I'm the only one here year-round, so you're very welcome to visit!"
Luke was very grateful to Beorn. He had originally prepared himself for Beorn's refusal, or even hostility.
After all, the transformation ability was the foundation of the skin-changer race's power. If it were deciphered by outsiders or a method to counter it was found, it would be like handing over the power of life and death to others for the skin-changers.
But Beorn allowed Luke to research on him, which was a great trust.
Luke owed him a favor, so he naturally had to repay it.
He thought for a moment, since Beorn had magic within him, he would make a wand for him.
Hearing that Luke was going to make him a wand, Beorn was also very pleasantly surprised.
"Is that possible? I mean, I'm just a skin-changer, can I really cast spells with a wand?"
Luke nodded affirmatively.
"You have magic within you. As long as you have a wand, of course you can cast spells. If you don't believe me, you can try with my wand."
Luke handed his wand to Beorn and taught him the most basic Lumos spell.
Luke's wand was naturally not suitable for Beorn, but it was not difficult to cast a simple Lumos spell with it.
As a point of light glowed at the tip of the wand, Beorn looked as if he had seen the most wondrous thing, a very happy smile appearing on his face.
He immediately eagerly requested to Luke: "Luke, please make me a wand, this is too magical!"
Luke smiled and nodded.
"Of course, that's what I was going to do."
To make a wand for Beorn, the first step was naturally to find a suitable wand body and core for him.
He had Galadriel's hair and giant eagle feathers that were suitable for a wand core.
However, when Luke took out these two, neither was compatible with Beorn until Beorn brought out a Warg he had killed the day before. Only then did Luke find a suitable wand core for him from the Warg – a Warg's heartstring.
As for the wand body, Mirkwood also had many magical trees.
Luke rode his broom to Mirkwood and found a suitable wand body for Beorn, which was a section of heartwood cut from a very old oak tree.
After collecting the materials for the wand, Luke began to make the wand for Beorn.
However, Luke did not intend to make it here.
The wand-making process was complex and time-consuming. He had been away from Lake-Town for some time and didn't know if the Orc army had arrived.
Especially that giant dragon, he didn't know if it had been well-behaved during his absence.
"Beorn, interested in experiencing Floo Powder travel?" Luke invited him with a smile.
Gandalf was busy preparing for the arrival of the Orc army, and he couldn't just do nothing.
It was also a good opportunity to invite Beorn to Lake-Town to join the fight against the Orcs.
He remembered that in the original timeline, this individual also participated in the Battle of Five Armies, dealing heavy blows to the Orcs, and even killing Bolg, Azog's son.
Hearing that it was about fighting Orcs, Beorn agreed without even thinking.
His kin had all died at the hands of Orcs, and his hatred for Orcs was deeply ingrained. He would agree without hesitation to anything that involved killing Orcs.
So, after arranging for the livestock, the two used Floo Powder to teleport directly to Lake-Town through the fireplace.
In the fireplace at Lake-Town, green flames flashed, and Luke emerged first.
The next second, the tall figure of Beorn appeared, accidentally inhaling some soot. He coughed awkwardly, hunched over, as he crawled out of the fireplace.
Seeing this, Luke waved his hand to clear the soot from him and asked with a chuckle.
"Beorn, are you alright?"
Beorn coughed until tears came to his eyes, waved his hand, his face unreadable.
"Cough cough I'm fine—!"
Bilbo heard the commotion and walked in from outside. Seeing the two, his eyes lit up, and he quickly ran forward.
"Luke, and Mr. Beorn, how did you come together?"
"Long time no see, Mr. Baggins." Beorn greeted politely. He had a good impression of this Hobbit.
Luke also explained with a smile: "Beorn is a guest I invited. He will join us in fighting the Orcs."
"By the way, where's Gandalf? Has he not returned yet?"
Bilbo shook his head.
"Bard and the residents of Lake-town have all migrated here, but Gandalf has not returned yet. Bard said he went to Mirkwood, wanting to persuade the Elves to ally with humans and Dwarves."
Luke shook his head upon hearing this.
Gandalf's trip would probably not be smooth.
Thranduil was not an Elf with a broad mind like Elrond; he only cared about the Elves of the Woodland Realm.
Not to mention allying with Dwarves, don't even think about it.
Putting the matter aside, he then asked: "What are Bard and the others doing now?"
"Bard and the others are currently building defenses, preparing to mend the gaps in the city walls so they can withstand Orc attacks," Bilbo said.
"Then let's go take a look together!" Luke said.
Immediately, the three went together to Bard's location.
Along the way, Luke looked at the residents of Lake-town, who were setting up makeshift tents using the ruined walls as foundations, and couldn't help but frown.
It was now late autumn, early winter, and the temperature in Lake-Town, located in the north, was starting to get cold.
Such crude living conditions could lead to people freezing to death.
The three arrived at the city gate.
At this time, Bard and the men were moving the stones, piling them up one by one in the gaps of the city wall.
After moving a large stone, Bard took a breath, saw Luke and the other two, and immediately showed surprise and happiness. "Luke, Bilbo said you went on a long journey, I didn't expect you to be back so soon!"
"Are you repairing the city walls?" Luke asked.
Bard nodded.
"Although the walls of Lake-Town are severely damaged, they can still be used. I want to repair the city walls as quickly as possible before the Orc army arrives, so we can prevent the Orcs from entering the city and harming the residents."
"Since that's the case, I'll give you a hand too." Luke said, drawing his wand.
Then he waved his wand at the broken city walls.
"Reparo~"
The next second, time around them seemed to flow backward. Except for the areas burned by dragon fire, the city walls were continuously repairing, scattered rubble reversing, filling in each damaged gap.
