After opening up to the Fourth Gate, Natsuki felt a slight tingling in his body, and his skin started to turn red.
However, his own strength was skyrocketing.
He just stomped his foot lightly and could make a large pit, and his running speed was astonishingly fast.
During the Chunin Exams, Xiao Li opened the Fourth Gate and fought Gaara, scaring Gaara into a daze.
Although Gaara had his mother's protection, his own reaction wasn't enough.
He couldn't see Xiao Li's movements at all.
If it weren't for Xiao Li himself taking significant damage and having gaps in his attacks due to pain, Gaara wouldn't even have had time to activate his sand clone and would definitely have been severely injured by Reverse Lotus.
At that time, Gaara was estimated to have the strength of an average Jonin.
In other words, Xiao Li could briefly unleash the power of an average Jonin.
"What about me? Do I have the power of an Elite Jonin when I open the Fourth Gate?
However, if it's the level of Kakashi or Kai, I definitely haven't reached it yet."
Then, continue to open the later gates, anyway, he won't die!
"Fifth Gate, Gate of Closing, Open!"
"Sixth Gate, Gate of Joy, Open!"
By the Sixth Gate, Natsuki felt that the damage he was enduring was even greater, and the pain in his body was even harder to bear.
If his physical body wasn't strong enough, he would have probably been torn apart long ago.
However, even so, he still had to have a strong enough will to endure this pain that felt like his body was being ripped apart.
Natsuki didn't waste time either.
According to the technique on the scroll, he directly leaped into the air and unleashed straight punches like crazy.
The straight punches frictioned the air, and the force of the punches instantly seemed to turn into fireballs, blooming in the air, like a fire peacock spreading its feathers, so beautiful and magnificent.
Of course, if the enemy was currently enduring this attack, they would only feel terror.
Right, Kisame Hoshigaki!
Natsuki performed Morning Peacock once and became somewhat addicted, so he continued to perform it, striving to become proficient, anyway, he wouldn't die, and with infinite stamina and infinite Chakra, as long as he could endure the pain, he could do whatever he wanted.
An hour later, Natsuki stopped using Eight Gates because it was too painful.
Even if there was no self-inflicted damage, the pain was present, and his body was smoking, he couldn't bear it at all.
"Looks like I need to train harder.
My future training plan needs to be adjusted, especially regarding enduring pain.
I need to do special training, otherwise I might pass out from pain when opening the Seventh Gate in the future."
Natsuki secretly planned, and after recovering for a while, he chose to continue.
The state of the special laboratory is very precious and must not be wasted, otherwise the food wouldn't even taste good.
"Next, I'll first get familiar with the first few gates, striving to be able to instantly open the later gates in the future, instead of opening them one by one.
That way the wind-up is too long, not only might I miss attack opportunities, but I might also be interrupted by the enemy."
So, for the next few hours, Natsuki kept opening and closing the gates.
From the First Gate to the Sixth Gate, he opened and closed them frantically until he was familiar with them.
By the time he could instantly open the Sixth Gate, there were only ten minutes left before the special laboratory ended, and he had a crazy idea in his mind.
"Increase gravity by one time! Sixth Gate, Gate of Joy, Open!"
Natsuki seemed to burst out like a Saiyan, his skin was red, but green energy flowed around his body, and the increased gravity couldn't press him down at all.
"Increase gravity again!
Seventh Gate... Can the Seventh Gate be opened!
Increase gravity again!
Seventh Gate, Gate of Shock, Open!"
Buzz!
Terrifying pain swept through his entire body, making Natsuki almost faint from the pain, but he bit his lip and endured it, then decisively followed the technique and began to compress the air with his straight punches, compressing the surrounding air into a tiger shape, and then punched it out.
"Daytime Tiger!"
Boom!
It was as if the world had collapsed.
And Natsuki also fainted directly, and was ejected from the training room, lying on the bed motionless, covered in sweat.
When Natsuki woke up, he saw Tenten anxiously holding a wet towel and wiping his sweat, while Shino stood silently beside her, worry written beneath his sunglasses.
"Natsuki, you're awake?
You really scared me to death!"
Tenten's tears came down, and she directly threw herself into Natsuki's arms, "Wuwuwu! You've been unconscious for a whole day, you know?
The doctor said you seemed to have fainted from pain, but there wasn't a single scratch on your body.
What on earth did you do!"
Natsuki showed an apologetic smile and reached out to touch Tenten's hair: "I'm sorry, I made you worry."
Shino added: "Today you didn't come to school, so I thought you overslept after training all night.
So I came to see you at noon, and saw you sleeping with my bugs, and thought you were fine.
It wasn't until after school in the afternoon that I came to see you again and found that you hadn't woken up yet, that I realized something was wrong.
Fortunately, Tenten arrived in time and opened the door, and we took you to the hospital."
So that's how it was!
Natsuki looked at the surrounding environment, and he was indeed in the hospital.
But, I made Tenten and Shino worry, didn't I? I really shouldn't have messed around at the end, it hurt so damn much.
After Tenten recovered, she put her hands on her hips and questioned, "Alright, tell me, what happened? If you don't explain clearly, from now on... from now on, I won't talk to you anymore!"
Saying this, she was about to cry again, so Natsuki quickly got up, hugged her, and comforted her.
Shino also said, "Natsuki, you really went too far this time. Although I don't know how you do your research, Tenten and I were genuinely worried."
Hearing this, Natsuki sighed.
He thought for a moment, then suddenly whispered, "Shino, see if anyone is eavesdropping around us."
Shino understood that Natsuki was about to speak, so he sent out his bugs to monitor the surroundings, and only after confirming there was no one did he nod, then pricked up his ears, waiting for Natsuki to speak.
Tenten also looked up, staring directly at Natsuki, not letting him lie.
Natsuki then changed his explanation: "Actually, on the evening of the first of every month, I enter a place that's like a dream.
In that place, I can't be harmed, I have infinite stamina and infinite Chakra, which is especially suitable for researching Ninjutsu, secret Ninjutsu, and even forbidden Ninjutsu.
All the new things I've come up with before were researched in that place."
Although Tenten and Shino felt it was absurd, it seemed to be the only possible explanation.
Moreover, looking at Natsuki's eyes, he didn't seem to be lying.
"What about this time?" Tenten stared at Natsuki's eyes, unwilling to miss the slightest change.
"This time, I was training in the Eight Gates."
Natsuki was also a bit annoyed, "Although that place is immune to damage, pain still exists.
I tried opening the Eight Gates up to the Seventh Gate, and even used Teacher Kai's ultimate move, Daytime Tiger. Its power was immense, but my body really hurt, and the pain was so intense it made me faint.
I'm really sorry for making you worry, I was actually scared myself."
So that's how it is!
Tenten believed him, because she had privately asked Teacher Kai about some things regarding the Eight Gates.
Opening the first three gates wouldn't cause problems, at most just fatigue, which was also why Natsuki only allowed her to open the first three gates.
However, opening the latter four gates would damage the body, requiring sufficient physical strength and firm willpower to use; otherwise, the body wouldn't be able to withstand it, and the mind wouldn't be able to endure the terrible pain.
