Uchiha You was wearing a thick vest filled with lead weights and was running at the edge of the village, panting.

Although it is called running, it is actually slower than walking. It is almost taken one step at a time. Each step leaves a deep footprint, and sweat drips onto the ground like rain.

Most ninjas excel in speed and agility, and any graduated Genin can run at over 100 kilometers per hour. For example, Uchiha Yu can run at 200 kilometers per hour.

But that was the normal load-bearing state. He was now carrying a full 650 kilograms of weight on his back, and he had to use all his strength every step he took.

When he first went out, he could still run, but after running half a circle around the village wall, he was completely exhausted. After his physical strength was seriously reduced, the strongest feeling he had was not the weight, but the change in his center of gravity caused by the weight, which interfered with his movements.

Uchiha You is now like a hammer, with the head of the hammer facing upwards, and he has the tendency to fall down at any time.

Maintaining balance on an object that is ten times heavier than your own body weight while walking is much more difficult than simply walking with your legs lifted.

Soon most of his physical strength was consumed, and then it was expelled from the meridians and scattered on the chakra tops of his limbs and bones.

The amazing thing is that chakra does not circulate in the meridians, but can communicate with each other through the circulating natural energy, and exert greater power. Uchiha You can actually carry heavy objects, run at a speed of 60 kilometers per hour, and even use chakra to protect tree branches, and then jump on the branches like a monkey.

But the weight was too heavy after all, and the chakra was exhausted after a short time.

The biggest benefit of practicing the immortal way after building a foundation is that it will not drain the chakra from the body's cells, no matter what.

You can use as much as you have above the safe value, but after reaching the safe value, don't even think about using a single drop.

So, only the exhausted muscles were left to hold on, and this was why Uchiha You was so tired.

But it was this most difficult time that was his real time of practice.

Without the protection of chakra, under the pressure of 650 kilograms, the muscles, fascia and bones will be severely damaged with every step.

Before the feeling of pain reaches the brain, the natural energy of fire will spread through the meridians, instantly repairing the damaged body, and the repair will also bring a little bit of subtle enhancement.

Following closely behind the pain signal, the itchy signal caused by injury recovery and the most powerful comfort signal caused by reinforcement arrive at the brain one after another.

The feeling of pain, itchiness and pleasure is simply indescribable.

Uchiha You couldn't stop and moved forward step by step, enjoying wave after wave of wonderful feelings.

[Xiu Xian... it's really addictive! ]

Suddenly, a rumbling sound came from behind. Uchiha You immediately felt something was wrong and wanted to cover his ears, but found that he couldn't raise his hands at all.

"It's over, I'm going to die!"

The rumbling sound was also the sound of heavy footsteps. As the source of the sound got closer, the sound became louder and louder, and even the ground began to vibrate rhythmically.

"Yo——, this is unbelievable! Kai, did you see that? This Chunin is still holding on, it's amazing!"

[I am not a Chunin, and my vest is not a Chunin standard vest! ]

[Forget it. I can’t possibly convince these two stubborn guys. Besides, I have completed my promotion mission and can be considered a quasi-Chunnin.]

"I saw my father!"

"Although his speed is very slow, this is because our training methods are different. We cannot carry such a heavy burden, so we can't underestimate him!"

"Father, this senior is a Chunin, and you are just a Genin, how can you judge him..."

Bang! (The fist hits the head)

"ah!!"

"You're distracted, Kai!!"

"Focus! Only by focusing can you make progress!"

"Look at this Chunin, how focused he is! You are slacking off, you are wasting your youth!"

Bang! (Another punch)

"ah!!"

“Youth is the most precious thing. You must work harder so that you can have a glorious day!!”

"yes!"

"come on!!"

"come on!!"

Two ninjas wearing green tights, strange orange scarves, with shiny black hair and thunderous voices, each holding a stone that was a circle larger than themselves, staggered past Uchiha You.

This is not the first time the two sides have met, and even today is not the first time.

The necessary greetings had already been made, so the two green-skinned ninjas simply grinned at Uchiha Yu, blinded his eyes with their shining front teeth, and ran away.

"Come on! We only have two more laps to complete our goal of circling Konoha Village ten times today. We're almost there!"

"Yes! Father!"

"youth--!"

Uchiha You did not stop, but his body trembled even more violently. He only breathed a sigh of relief when he could no longer hear the energetic shout.

A gray shadow rushed out and jumped directly onto Uchiha You's head. It was Miwa Masayo.

The tabby cat scratched his ears and said with lingering fear: "The mental impact of the Might family... is too strong. There is no way I can adapt to it."

"It has to be repeated ten times throughout the morning, Yuu, how do you bear it?"

Uchiha You pointed to his ears and said, "I sealed my hearing and closed my eyes just now."

"Closing your eyes and blocking your hearing is indeed a solution, but how do you know they left?"

"Once they have gone far away, you will come back, Miwa Masayo."

“…Good idea.”

"Thanks for the compliment."

Miwa Masayo looked back and said, "It will take another 20 minutes for the father and son to catch up. Finally, we can have some peace and quiet for a while."

"Why is there such a strange ninja in Konoha Village?"

"Haha, the ninjas from the Might family are indeed very strange."

"You know them, meow?"

"Well, I can't say I know them... After all, I know them, but they don't know who I am."

"Meow?"

Uchiha Yu did not explain to Miwa Masayo how special Might Dai and Might Guy were.

This father and son are the people who impressed him the most in this world, far more than the future male and female protagonists. After all, the guy who stood at the top of the ninja world by relying on his father is not qualified to compare with the feat of a mortal who attempted to kill a god.

However, after three days of continuous contact, Uchiha You began to have great doubts about their mortal bodies.

He has the most abundant chakra among ninjas of the same age, powerful and mysterious natural energy that can perfectly repair physical injuries, and he also has the Uchiha family's systematic training methods.

With so many supporting conditions, Uchiha You was able to carry out three hours of extreme training.

If this limit is exceeded, his body's self-healing ability will not be able to keep up. Not only will he not become stronger due to training, but the results of previous training will even be seriously weakened.

But what do Might and his son have?

There were only the most basic physical skills taught in the ninja school, the forbidden technique of Eight Gates Ninjutsu, and the training method that Might Guy had spent twenty years to explore.

They don't even have money to eat meat every day.

Under such simple conditions, the two were able to perform extreme training for more than eight hours a day, and had to use the remaining time to work, otherwise they would have no money to support their lives.

Uchiha You seized the opportunity to perform an illusion, then checked it carefully.

They really don't have any special blood, perhaps what supports them is their strong will.

Miracle.
