"Vortex wind, even if it is a task given by Mr. Watergate, once you are unconscious more than three times, I will not care about you anymore!" Kakashi whispered to Lin Feng who was lying on the bed.

Lin Feng was lying on the hospital bed, but he didn't know what Kakashi was talking about. Of course, even if he heard Kakashi's words, there was nothing, after all, the current Lin Feng didn't have any ability to resist, so he could only go along with it.

When Lin Feng woke up, it was already past two o'clock in the afternoon, and when he opened his eyes, he immediately saw Kakashi meditating in front of the window.

"How could I be in the hospital?" Lin Feng was taken aback when he saw that he was lying on the hospital bed, and couldn't help but ask.

"When you were practicing, your physical strength was overdrawn, you exceeded your limit, and you passed out." Kakashi said lightly.

"You sent me back, thank you so much." Lin Feng sat up from the bed and said to Kakashi.

"If you really want to thank me, don't be unconscious again in the future." Kakashi said indifferently and walked out of the room.

Lin Feng was stunned for a moment, and then came to his senses, although Kakashi had become a shinobi, after all, his age was not very large, and his strength still had a lot of room for improvement. I'm afraid that teaching himself in place of Bo Feng Shuimen has already caused him a lot of trouble, and if he faints every once in a while, Kakashi will naturally feel very uncomfortable.

"I'm sorry, Kakashi, for the trouble. However, my current physical fitness is too poor, and if I don't work hard, I'm afraid I won't be able to save my life in the future. Lin Feng said secretly in his heart.

"But I will promise that I will definitely try to be as little comatose as possible in the future, and no matter what, I will continue to improve."

Martial arts arena.

Kakashi looked at Lin Feng with an expression, and said in his mouth: "Yifeng, you can refine the chakra by yourself now, although the amount of chakra you have now is still relatively small, but as you get older and continue to cultivate, your chakra amount will continue to increase. What I'm going to teach you next is how to control the chakra and how to get the most out of it with the least amount of chakra. ”

Lin Feng listened carefully, not daring to miss a word, he knew that this was very important for his future cultivation, whether it was learning the medical ninjutsu left by Tsunade, or the growth of his strength, it would be of great help.

In general, there is not much difference in the amount of chakra, but for the same upper ninja, the difference in strength between them is huge. Take Kakashi and Sarufei Asma as examples, both of them are supreme shinobi, and in terms of chakra amount, even Sarufei Asma has more than Kakashi, but Kakashi's strength is far superior to Sarufei Asma. Although Kakashi's Bloodwheel Eye is a very important factor, the precise control of Chakra is the most important reason why the combat power of the two is so different.

In the original book, the genius of the Uchiha family, Uchiha Itachi, is recognized as the person who has reached the pinnacle of his use of chakra, and his exquisite control over chakra is unmatched even by Madara Uchiha. Of all the shadow-level characters, I'm afraid Uchiha Itachi has the least amount of chakra, but his strength is also among the best in the entire Hokage, and few are his opponents!

"Vortex and wind, do you remember it clearly?" Kakashi said a lot in one breath and finally asked.

"Well, I remember everything, but there are some things I still don't understand." Lin Feng nodded and said.

"It's okay, you go and practice by yourself for a while, and if you encounter something you don't understand, come and ask me." Kakashi Road.

Lin Feng walked towards a small river next to the martial arts arena, which was a small river that ran through Konoha and was very beautiful, and made a great contribution to the prosperity of Muye Village.

"Concentrate your mind, concentrate the chakra on the soles of your feet, and then use the energy of the chakra to lighten your body and stand on the water by yourself." Lin Feng silently recalled what Kakashi had just said.

"Chakra!" Lin Feng shouted in his heart, and suddenly a clear and palpable energy slowly flowed from his dantian to the soles of his feet, and a wonderful feeling surged into Jiang Hua's heart, and he felt that his body had become much lighter.

"I'm coming." Lin Feng shouted in his heart. He lifted one foot and stepped on the surface of the river, hanging in the air for a long time, not falling. He was experiencing the feeling he had just had, and he didn't think he was a peerless genius who couldn't succeed in one go. Even if he failed, he had to remember that feeling, and the feeling would be of great help to his cultivation in the future.

"It took me a week to walk on the water, and I wonder what you can do with the whirlpool? This first day of cultivation refined the chakra person. Kakashi stood on a large tree and looked out from afar. There was both anticipation and some uneasiness in his heart.

"That's how it feels." Lin Feng's tightly closed eyes opened violently, and he shouted. He stepped into the river, and to his shock, he actually had the feeling of stepping on the ground, and his feet were not submerged in the water!

"That'...... What is that? Lin Feng was frightened, he seemed to see a strange space between his feet and the surface of the water, and that space isolated Lin Feng's feet from the surface of the water.

"Is this the repulsion of Chakra and Watergate?" Lin Feng muttered to himself in his heart, shocked.

What exactly is a chakra, and why does it have such wonderful abilities?

"What? He actually managed to walk on water for the first time? In the distance, Kakashi was completely stunned, unable to keep calm any longer.

Could it be that this kid named Vortex Yifeng could be a genius that is rare in a hundred years? You must know that when Bo Feng Shuimen, a peerless genius recognized by the ninja world and his own teacher, walked on the water of cultivation, it took only three days to complete!

Could it be that the talent and talent of Uzumaki Yifeng is still above his own teacher?

"Ah...... Ah! Suddenly, Lin Feng felt a softness under his feet, and his body slid into the water at once, and a mouthful of water immediately poured into Lin Feng, who was defenseless.

"Ahh Lin Feng screamed, but there was no sound, and his body sank to the bottom of the water.

He is only seven or eight years old now, how can he know how to swim? In a panic, he drank four or five sips of water in a row, and his eyes were black, almost suffocating.

Suddenly, at this dangerous moment, a powerful hand grabbed Lin Feng and dragged him out of the water.

"Ahem, ahem!" Lin Feng's face turned pale, he knelt on the ground and coughed incessantly, spit out the water he drank, and it took a long time before he recovered.

"How? No problem, right? A gentle voice came.

"Mr. Watergate, it's you!" Lin Feng raised his head, he didn't expect that it was Bo Feng Shuimen who came to save him.

"Yifeng, the first day we met, I planted the Flying Thunder God technique in you. I found out you were in danger just now, so I came straight over. Bo Feng Shuimen said with a smile.

In fact, Lin Feng's every move fell in the eyes of the third and fourth generations. The high talent of Uzumaki Yifeng had completely shocked the two of them, they were happy to think that they had picked up a treasure, and they all agreed that if Lin Feng could be cultivated well, his future achievements might even surpass the three ninjas!

However, when they were happy, they found that Lin Feng had accidentally fallen into the water, and the place where Kakashi was standing was far away from Lin Feng, and it was too late to rescue, so Bo Feng Shuimen directly used the 'Flying Thunder God Technique' and traveled through the space to come here.
