Natsuki dared to mess around because he wouldn't be harmed in that special place, but he overestimated his willpower, or underestimated the pain of opening the Seventh Gate. In short, the pain was so intense it made him faint, showing that the price for obtaining great power is truly high.
Given Natsuki's strength, it's hard to imagine how much pain it would take to make him faint from the pain.
It's a good thing Natsuki didn't recklessly open the Eighth Gate, otherwise he might have died from the pain.
Tenten finally let out a sigh of relief, then suddenly reached out, twisted Natsuki's ear, and said angrily, "That's what you get for messing around! That's what you get for messing around! Do you want me to become a widow before I even get married? Will you dare to do it again from now on?!"
"I won't dare, I won't dare! Wife, be gentle!" Natsuki begged for mercy dramatically.
"Pah! Who's your wife!"
Tenten spat out a retort with a red face, and seeing this guy's pretentious look, her mood improved quite a bit. Before, she was really scared to death.
Shino was fed a mouthful of PDA, but he was used to it.
However, he asked, "Natsuki, are the Eight Gates very strong?"
Natsuki immediately said solemnly, "Very strong!
When I opened the Seventh Gate before, I felt defeating the Hokage wouldn't be difficult.
However, with my current body, opening the Sixth Gate is already the limit.
I need to strengthen my training in the future. I look forward to the day I can open the Seventh Gate and cripple the Six Paths Sage!"
Cripple the Six Paths Sage?
You really have lofty ambitions!
However, Shino didn't doubt him, because this friend of his was truly mysterious.
Being able to enter a special dream on the first of every month for intense training with almost no risk, how could he not become powerful?
Shino immediately felt a sense of urgency. His good friend would definitely be extremely strong in the future, and he couldn't be weak, otherwise, how could his friend feel at ease entrusting his back to him?
At this moment, Shino's expression changed: "Someone's coming."
Natsuki and Tenten immediately stopped fooling around. Soon after, someone knocked and came in. Unexpectedly, it was Shikamaru, Choji, Ino, Sakura, Naruto, Hinata, and Kiba, and even Sasuke was outside in the hallway.
Our friends are here!
Ino laughed and said, "Outside the hospital, I heard someone begging their wife for mercy. Who has such thick skin that they're already calling someone their wife~!"
Natsuki and Tenten immediately couldn't help but blush. It was fine for the two of them to mess around with each other, and it didn't matter if Shino heard, but it was a bit embarrassing to be heard by others.
"Ah! Tenten is blushing!" Ino and Sakura laughed so hard they couldn't close their mouths.
"It's not just Tenten, that thick-skinned Natsuki is blushing too."
Shikamaru and the others put down the fruit basket and were relieved to see Natsuki was fine, but they still asked, "Natsuki, what happened to you?
We heard you fainted from pain, but you don't look injured."
Natsuki explained, "Last night, I was training in a certain secret Ninjutsu at home, and it was so painful that I just fainted from the pain."
Everyone was stunned upon hearing this, immediately understanding the power of this secret Ninjutsu; being able to make Natsuki faint from pain without injury was definitely not ordinary.
I didn't expect Natsuki to be so dedicated!
It looks like graduation is approaching, so Natsuki must be getting anxious too!
For a moment, everyone felt a sense of urgency. Shikamaru, Choji, and Kiba, being from prominent clans, also wondered if they should start learning their clan's secret Ninjutsu.
Ino and Hinata, on the other hand, said they had been learning for a while, they just didn't show it usually.
Naruto could only feel envious.
He not only envied Natsuki for having a secret Ninjutsu to train, but also envied Natsuki for having a girlfriend.
Damn it, everyone is the same age, so how did Natsuki manage to snag such a cute girl like Tenten, and even call her his wife?
There's really no comparing yourself to others!
Sasuke's eyes, meanwhile, flickered, and the sense of urgency in his heart intensified.
He had only just learned tree climbing and water walking in the past few days, already falling far behind Natsuki. Now Natsuki had actually started training in a secret Ninjutsu, and from what Natsuki said, this secret Ninjutsu was very powerful. Wouldn't he be left far behind, unable to defeat Natsuki ever again?
It wasn't that he was obsessed with defeating Natsuki, but he felt that if he couldn't even defeat someone his own age, how could he avenge his older brother?
"It's good that you're fine."
Sasuke dropped this sentence, turned around, and left. He had no more time to waste.
The friends didn't bother them too much. After greeting him, they also left one after another. Even Shino left, leaving the space to the couple.
However, Natsuki didn't plan to stay in the hospital. He called the doctor for a check-up, confirmed he was fine, and then went home with Tenten, just in time to meet the Ninjutsu Shop Owner who was about to leave with a lunchbox.
The Ninjutsu Shop Owner was stunned to see Natsuki was fine and subconsciously hid the lunchbox: "Didn't they say you fainted? How are you already discharged?"
Natsuki smiled and said, "I made you worry, Father-in-law. It was just a side effect of training in a secret Ninjutsu. The doctor said I'm fine and recommended I go home and rest properly.
Were you going to visit me, Father-in-law? Let me see what delicious food is in the lunchbox!"
Saying this, he directly snatched the lunchbox, not giving the Ninjutsu Shop Owner any time to react.
The Ninjutsu Shop Owner felt relieved inside, but put on an annoyed face: "I was going to feed the cat!"
Natsuki had already opened the lunchbox and started eating: "...Yes, yes, yes, I'm the cat, Father-in-law, your cooking is great!"
The Ninjutsu Shop Owner choked, turned away pretending not to care, but a smile played on his lips.
Tenten saw it in her eyes, and her eyes also held a smile, but she was also a little impatient.
I really, really want to grow up quickly, and then get married...
In the following days, Natsuki didn't dare to mess around and obediently rested.
He still had lingering fears about the pain of opening the Gate of Wonder and needed a few days to recover and refine his training plan.
Currently, he had increased the gravity in the gravity training room to eight times and planned to increase it to ten times later.
Don't think ten times gravity is small. What people say online about ten times gravity being ten times body weight in terms of load is completely wrong; gravity and load are two completely different things.
A load is just supporting an object of a certain weight, while gravity is a force applied to the entire body.
Including blood, bones, internal organs, and even the brain, everything has to withstand this force, which cannot be compared to carrying a load.
When a person is in an elevator or on a roller coaster, the acceleration causes instant dizziness. The slight increase in gravity is negligible, but the body cannot withstand it.
Simply put, a person can generally only withstand two to three times gravity; five times gravity would immediately cause them to faint.
Astronauts have stronger endurance and can briefly withstand ten times gravity, likely the extreme acceleration during rocket launch, but it can only be endured for a short time.
In Dragon Ball, Son Goku also often trained under gravity conditions.
After his first death, he went to King Kai's planet, and just ten times gravity made his training difficult. At that time, he had the power to destroy the Earth at any moment, yet it took him a considerable amount of time to adapt to ten times gravity, showing that ten times gravity is truly not simple.
As for one hundred times gravity, it was already the limit when Son Goku took the spaceship to Planet Namek. After finishing his training, he thrashed the Ginyu Force. At that time, the captain of the Ginyu Force was already moving at near light speed, but still couldn't defeat Son Goku.
Although the topic has strayed, the main point hasn't changed.
Gravity training is very effective, but it must be done within one's limits.
