Sakura Haruno glanced up at the girl who was talking to her, her short brown hair and delicate face were a beautiful young lady.

She wiped the sweat from her head, got up from the ground, smiled and said, "No thanks." ”

"But it's not much use for you to train like this." Gray Yuan Wai continued, and at the same time, his hand waved lightly in the air, and a stone next to him turned into powder, and the wind blew into the air.

Sakura Haruno looked a little moved, hesitated for a moment and asked, "That, may I ask who you are...?" ”

"My name is Gray Plains, a scientist." Gray Yuan said after a moment's thought.

"Gray Plains?" Haruno Sakura read a sentence softly, and at the same time searched in her mind, she had never heard of this person, "That, I'm ** Sakura, we don't know each other, why do you want to help me?" ”

"The reason is a little bit complicated, mainly because of a bet." Gray Yuan smiled and said, I didn't expect to do such a childish thing, "If you don't believe me, can you tell me who your guide is Shinobi?" I can communicate with him first. ”

"Bets?" Sakura Haruno blinked her glasses, not understanding what she meant, "My guide Kashinobu is Kakashi Hachiki, he may be in Konoha Hospital now, with my teammates." ”

"Kakashi?" A figure flashed in front of his eyes, "Do you mean that ninja who often wears a mask and can't see his face?" ”

"I guess, Kakashi-sensei also likes to cover one of his glasses with his forehead." Sakura Haruno thought for a moment and continued.

"That's right, I just met him, he's in Konoha Hospital, right, I'll go look for him first." Gray Yuan took out a piece of paper from his bosom as he spoke, handed it to Sakura Haruno and said, "When I go to communicate, you can take a look at the things on this paper first, and ask me when I come back if you don't understand the things you don't understand." ”

Haruno Sakura fruited paper, looked down, there were a lot of things densely written on it, and when I just wanted to ask what it was, I found that Gray Yuan Wai was gone.

At this time, in the training ground, Jiao Wen took Xiao Li to the side of a small waterfall, then turned to look at him and said, "Xiao Li, as a genius who uses the Eight Gate Dun Armor, your attack power and speed can be improved by opening the door, and what restricts your use of this secret technique is your physique. ”

"My constitution?" Xiao Li clenched his fists, felt the toughness of his skin, and then asked Jiao Wen, "Then how should I exercise my physique?" ”

"I have also considered this, first of all, external stimulation, just as muscle training needs to tear muscle cells apart, and the same is true for physical exercise." Jiao Wen said and pointed to the waterfall behind them, "From now on, I want you to stand under the waterfall and use your body to resist the impact of the water, so as to strengthen your physique and exercise your use of strength." ”

"Yes, Mr. Jiao Wen." Xiao Li said very seriously, and then jumped directly to start training.

Jiao Wen stretched out his hand and pulled him down in the air, "Don't worry, I haven't finished yet." ”

Xiao Li rolled over and fell to the ground, waiting for Jiao Wen to continue explaining.

"Second, I have an exercise method here, called Haw Par Lei Yin, this method can make your muscles and bones, and after practicing deeply, you can also have enough exercise for your internal organs." Jiao Wen touched the tip of his nose and said, most of the exercises in the Hokage are for the epidermis, and the inside of the body has always been a neglected place.

It may not be appropriate to say that it is ignored, it should be impossible to exercise, and it is precisely because of this that these people are very fragile internally, and some internal strength can exert a 100% effect, which is equivalent to zero resistance.

And the exercise method of this tiger and leopard thunder sound comes from the national arts, through the body energy and muscle resonance to exercise other parts.

"Exercise?" Xiao Li scratched his head, "But I don't need to use ninjutsu." ”

"Don't worry, I know your situation, so this exercise method is not ninjutsu." Jiao Wen said and put on a posture, "I'll show you first." ”

Then where Jiao Wen was standing, he let out a long hum, not from his throat, but from every inch of his body.

Xiao Li circled around Jiao Wen twice, and found that his body seemed to shake slightly, and he learned to stand in place like Jiao Wen, and began to look for that feeling.

Jiao Wen was a little surprised when he looked at Xiao Li's movements, he was worthy of being a genius in physical arts, and he could do it very standard after just watching it once, but because he hadn't found the trick yet, there was no sound.

Jiao Wen walked over and patted his waist gently, "The force is not a piece, it must be connected as a whole." ”

"A whole?" Xiao Li was a little puzzled, and then asked.

"Yes, the force rises from the ground and permeates the whole body." Jiao Wen gave him another demonstration.

Xiao Li watched Jiao Wen's movements, and then began to exert himself again, this time finally a little successful, like a cat's humming sound coming out of his body, and after a while, he was sweating.

Then he suddenly lay on the ground with a lot of strength, panting for breath, and his whole body was soft.

"Hmm... Okay, that's pretty much what it means, you take a break, sweat, and then go and stand at the bottom of the waterfall, and when you can't bear it, you come out to practice your internal organs, and then you take a break, and so on. Jiao Wen said to Xiao Li.

"Okay, I got it." Xiao Li nodded and said.

"That's okay, I'll go and dispense some potions first, it will hurt my body if I don't have any auxiliary tools like this." Jiao Wen said as he took out a large pile of reagent bottles from the space and placed them on the ground.

After Xiao Li rested for a few minutes, he took off his jacket and rushed to the bottom of the waterfall while stepping on the water, and the turbulent water slapped on his head at once.

The figure shook, almost didn't resist, and barely stabilized with a force on his feet, then stood up straight, felt the force of the water hitting his body, lightly hehe, took a horse step, and began to exercise.

Speaking of which, the physical fitness of people in the Hokage world is really good, and the impact of a waterfall like this is not small, but it seems that Xiao Li has been able to adapt.

Jiao Wen, who was watching from the side, moved his fingers slightly, and in an instant, the gravity felt by the water flow increased a lot, and the speed of the water flow also increased, and then Xiao Li felt that the pressure on himself suddenly increased a lot.

His feet slipped and he was washed into the pool, grunt, Xiao Li came out of the water, and glanced at the waterfall, why did the waterfall water suddenly become so fast...
