"The physical energy that is drawn from the cells of the human body, and the spiritual energy that has been accumulated over a long period of cultivation?" Lin Feng repeated quietly, carefully savoring Kakashi's words.

In the real world, Lin Feng's love for Naruto has almost reached the point of obsession, and he knows what Chakra is. However, understanding is understanding, and you really have to try it with your own body, after all, it's too ethereal.

"Yes, exactly. We ninjas extract these two energies from our bodies, fuse these two energies into chakra, and then activate this chakra energy through the action of sealing. Kakashi said as he made seven mudras in his hands.

"Boom......" In Lin Feng's incredible eyes, Kakashi opened his mouth and spewed out a water arrow.

"Whoosh!" The speed of the water arrow was extremely fast, and it hit a small tree as thick as a bowl not far away, and it actually broke the small tree!

"This ...... This is ninjutsu! It's amazing! Lin Feng's heart was shocked.

Obviously, what Kakashi had just performed was nothing more than an ordinary C-rank water escape technique. Even so, it is still easy to break the small tree with the thickness of the bowl!

If it hits a person, it will definitely kill it in one hit!

"How? Got it? Kakashi said.

"I ...... Still a little incomprehensible. Lin Feng shook his head. He doesn't like to pretend that he doesn't understand, because doing so will only harm himself.

"Hey!" Kakashi sighed, and secretly said in his heart, why would a genius like the fourth generation Hokage of the teacher find such a stupid person as an apprentice?

"Well, maybe it's easier to understand like this." Although Kakashi was very impatient, after all, it was explained by his teacher Bo Feng Shuimen, and he couldn't ignore it.

"Chakra is actually a fantasy, you know?" Kakashi suddenly said to Jiang Hua mysteriously.

"Something from a fantasy?" Lin Feng was very surprised, he didn't understand why Kakashi would say that.

"Have you seen Chakra?" Kakashi asked rhetorically.

"I didn't ...... No. Lin Feng thought about it seriously, and then shook his head.

"Actually, it's like this, Chakra can only feel, not see with the naked eye." Kakashi answered.

"One of the sources of chakra is spiritual energy, that is, the amount of chakra is related to a person's spiritual energy." Kakashi said.

"Do you mean that you can produce chakras by imagination?" Lin Feng's eyes widened in disbelief. If that's the case, then do ninjas still need to train all day?

"I can't tell." Kakashi shook his head and said, "All I know is that from the moment my father committed suicide, the chakra in my body increased almost fourfold at once!" ”

"Is there such a thing?" Lin Feng felt a little incredible. Could it really be that like the Uchiha clan, chakra is also a product of hatred?

Lin Feng thought of the legendary Six Dao Immortals again, that Immortal's greatest ideal was to lead the world to peace, could there be some connection between this?

"Yifeng, just saying it and not doing it will never have an effect, so you better try it yourself first." Kakashi said that it was not possible to go on like this.

"Through imagination, absorb the cellular energy in your body, and then fuse it with spiritual energy to refine chakra!" Kakashi pointed from the side.

"Through imagination, absorb the cellular energy in your body, and then fuse it with spiritual energy to refine chakra!" Lin Feng tried his best to eliminate the distracting thoughts in his mind, only thinking about Kakashi's words in his heart, and immersed all his thoughts into his body.

Suddenly, Lin Feng seemed to feel a strange energy rising from his lower abdomen in his body, slowly flowing all over his body, and he felt that his body actually had an unprecedented feeling of comfort at this moment.

"Is this Chakra?" Lin Feng was surprised and delighted in his heart. I succeeded in refining chakra in my first practice, am I actually a genius like no other? Or rather, the fairy who rescued him and threw him into the Hokage world did something to his body!

Otherwise, how could there be such a situation where the chakra was successfully refined in the first practice?

You must know that in the entire ninja world, except for a few extremely rare and powerful races such as the Uchiha clan, the Thousand Hands clan, and the Uzumaki clan, such a situation will occur. And the people who successfully refined the chakra in their first cultivation, almost every one of them has become a super existence in the ninja world!

For example, the Uchiha Madara of the Uchiha clan, for example, the Senju Pillar of the Senju clan!

At this moment, Kakashi was already stunned. He stood beside him in a daze, his eyes wide open, barely believing his eyes. Just now, Yifeng, who he thought was a fool, actually succeeded in refining the chakra for the first time in his cultivation, which was unbelievable. Even he was recognized as a genius, but it was only after a week of practice that he refined the chakra!

"No wonder Master Shuimen chose him as a disciple, he really has something extraordinary!" Kakashi's eyes flashed with a glint as he said to himself.

"Kakashi-san, is this what it looks like?" Lin Feng said excitedly while feeling the changes in the chakra in his body.

After refining the chakra, Lin Feng can practice ninjutsu. He had to learn as much as he could from the Nine-Tails before they attacked Konoha Village and the Bo Feng Shuimen couple died!

"Hmmm! You're good! Kakashi's heart was shocked, and he nodded and said, "That's all for today's lesson, you can go back, and I'll teach you the control method of chakra tomorrow." ”

"Is that all for today?" Lin Feng said with some dissatisfaction.

"Yes, that's all for today's lesson. Of course, if you don't want to walk, you can practice on your own. After Kakashi finished speaking, he turned around and walked towards the north, ignoring Lin Feng again.

"......" Lin Feng was helpless.

Sure enough, Kakashi was even more difficult to reach as a teenager. Lin Feng believed that if it weren't for Bo Feng Shuimen's relationship, Kakashi probably wouldn't even say a word to him.

"That's ...... Mike Kay? Lin Feng watched Kakashi walk away, and soon found a young man about Kakashi's age standing under a big tree in the distance. The young man was dressed in green, with a watermelon head and two thick eyebrows across his face.

With such a costume, who is not the "blue beast" Mike Kay?

Mike Kay, the master of physical arts in Konoha Ninja Village, has reached the point where there is no one before and no one after him. Lin Feng has always had great respect for this master of physical arts.

Mike Kay has cultivated his physical skills to an unparalleled level. With a beast-like strong physique, stoic willpower, and the forbidden technique "Eight Gates Dunjia Array", even if he doesn't use any ninjutsu or illusion, he will definitely not be weaker than anyone!

He is the strongest in physical arts, even the Hyuga clan, who are known as the strongest melee clan, and the Kaguya clan, who have corpse bloodlines, are far from being able to compare!
