Naruto : Ninja school teacher, I can become stronger by teaching

"Muyue-sensei, how long did I last this time?" Obito asked, wiping the water from his face and looking at Muyue with anticipation.

He felt like he had been in the river for a long time, maybe even an hour.

"You did very well this time, you lasted twenty minutes," Muyue praised him generously.

"Ah? Only twenty minutes? I thought it would be at least half an hour," Obito said, a little disappointed.

On the river surface, he not only had to constantly maintain his chakra output, but also watch out for Muyue's Water Style, observe the waves on the river, and be ready to dodge at any moment. Maintaining this state constantly made it feel like a very long time had passed.

"You've completed your chakra control training, you can start nature transformation training now," Muyue said with a smile.

"Mhm, I'll go down right away." Obito had been practicing water walking so much recently that he instinctively walked towards the river, only realizing what Muyue had said a few steps later.

"Finally, no more water walking!" Obito couldn't help but cheer, clenching his fist and jumping. He then quieted down when he noticed Shisui and Might Guy looking at him.

"Lately, with all this water walking, I'm starting to get used to the taste of this river water," Obito couldn't help but complain.

Water walking was different from tree climbing. With tree climbing, as long as he adjusted himself or Muyue caught him quickly, it was fine. But with water walking, if he didn't control himself well, he'd really gulp down water.

Thankfully, there weren't many people here, and the river water was clean and clear, without any strange smells.

"Want to practice more?" Muyue asked teasingly.

"No, no, I feel like I want to avoid rivers for a while," the tormented Obito chose not to be stubborn this time.

"Let's start nature transformation earlier. There are only fourteen days left until the competition," Obito felt that time was pressing.

Besides nature transformation, he also needed to improve his mastery of the Great Fireball Jutsu.

"According to my plan, there will be enough time," Muyue reassured Obito.

This was just training for a civilian competition, not training to fight Pain, so there was no need to exaggerate the nature transformation training.

With the teaching skill's boost, and Muyue's Great Fireball already at mastery level, it was very simple to help Obito improve his Great Fireball Jutsu.

After all, it concerned the reward from the training mission, so Muyue had planned it seriously.

Soon, Muyue's Shadow Clone brought a large wooden barrel. Muyue opened the barrel, took out an egg-sized ice cube from it, and handed it to Obito.

"Put the ice cube in your palm, then use chakra to perform nature transformation and melt the ice cube," Muyue said, explaining the first step of nature transformation training.

Nature transformation was a relatively difficult and advanced training in the process of ninja cultivation.

Even if you had enough chakra, if your nature transformation level for the corresponding ninjutsu wasn't high enough, the power of the ninjutsu would be limited.

Fire nature transformation training was a bit more dangerous than wind, because the burning nature of fire could affect the user.

Initially, Muyue wanted Obito to burn leaves, but if Obito couldn't instantly turn the leaves to ash, his hand would get burned by the burning leaves. So Muyue thought of ice cubes. Because of their sufficiently low temperature, they would only melt into water when encountering fire, and Obito's flames wouldn't be enough to heat up the water from the ice cubes.

"It's so cold," Obito gasped, holding the ice cube in his hand. It was still spring, and the temperature wasn't high in the morning without much sun.

"Then quickly release chakra," Muyue said, tapping Obito's head with two fingers together.

Obito flinched from the pain,缩了缩脖子 (shrank his neck), then began to guide his chakra to his palm, performing nature transformation before releasing it.

"When performing nature transformation, you must remember the characteristics of fire: burning and high temperature. Make your chakra burn and increase its temperature," Muyue reminded him.

Obito stared at the ice cube in his hand, nodded, and silently repeated the words "burning" and "high temperature" in his mind.

Two minutes later, Obito felt water appearing on his palm and instantly beamed with joy.

"Sensei, the ice cube is melting!" Obito said happily.

"Why don't you get another ice cube and try holding it for a few minutes?" Muyue suggested.

Obito curiously dropped the ice cube in his hand, picked up another similarly sized one, and held it without using chakra. Then he awkwardly realized that the degree to which the ice melted into water was only slightly less than before.

"The human body also has a temperature. If you hold an ice cube of this size in your hand, it won't melt slowly even without chakra," Muyue explained, rubbing his forehead.

Luckily, the weather wasn't hot now. If it were summer, Obito would have thought he was a small genius at nature transformation.

"Hehe, when using ninjutsu, I always use my mouth. It's a bit uncomfortable using my hands now," Obito scratched his head and explained.

"When performing nature transformation, you must always remember the nature of fire," Muyue said, while taking out a head-sized ice cube and holding it in his hand.

Sizzle, sizzle!

The moment Muyue finished speaking, a red light flashed, and the head-sized ice cube immediately turned into wisps of white smoke, directly vaporizing and floating into the sky.

"High temperature, burning," Obito mumbled these two words repeatedly, then continuously gathered and released chakra in his palm.

Soon, the morning was almost over. Obito already felt both his hands numb from the cold, and the skin on his hands had turned white and wrinkled from prolonged contact with water.

"Come to think of it, the river water doesn't taste too bad," Obito somewhat regretted not agreeing to Muyue's suggestion to practice more a few hours ago. This nature transformation training was even more torturous than water walking.

"Stop training for now, let's eat," Muyue called a halt to the three, then took out three lunchboxes and distributed them.

"Today's food smells so good!" Might Guy opened his lunchbox and immediately smelled a scent that went straight to his soul, along with a dazzling golden glow from the food.

"Muyue-sensei, something's wrong with this food, it's glowing!" Might Guy was a little dumbfounded.

"It's just the sun reflecting, eat up," Muyue said with a faint smile.

Might Guy took a spoonful and tasted it. His eyes instantly lit up, and he quickly scooped up spoonful after spoonful of fried rice into his mouth. "Delicious! Delicious!" Might Guy felt he had never eaten such delicious food before.

[You gave your disciple Golden Egg Fried Rice. Due to the disciple's extreme gratitude, the reward critically hit, and you obtained Chakra +100].

Muyue nodded to himself, the Chef skill was indeed powerful.

"Is Guy that tired from training today?" Obito felt Might Guy was exaggerating. Although Muyue-sensei's cooking was good, there was no need to eat so quickly.

"It does smell pretty good," Obito changed his mind slightly after opening his lunchbox. His was not egg fried rice, but a home-style stir-fry.

Obito first picked up some vegetables, then a mouthful of rice, and put them into his mouth. "Delicious!" Obito's eyes widened, feeling a taste he had never experienced before exploding in his mouth.

Then he frantically shoveled down the food, continuously stuffing it into his mouth, until Obito ate the chili pepper in the dish. A terrifying spiciness erupted, and Obito felt as if he had been transported to a volcano about to erupt, with hot and dry air all around him.
