A convenience store opened in Naruto

"From Zabuza's attitude, you can tell whether what I said is true or not," Ye Feng didn't pay attention to Zabuza's snort, and continued, "Dai was able to defeat the Seven Ninja Swordsmen with just the strength of a Genin, and even killed four of them. This shows how strong his taijutsu is."

"His son, Kai, inherited everything from his father and surpassed him even more. He is known as the 'Proud Blue Beast of Konoha'. Based on his Taijutsu alone, he has the strength of a Jonin."

"It's really scary when you think about it, everyone. Don't you think that the Seven Ninja Swordsmen are all jonin? Even so, under siege, Dai was able to kill four of them, and he was still a jonin."

"Think about Kai again, he's already a jonin, if he goes all out, how powerful would he be?"

"He will die!" Kakashi said in a deep voice, "After using that move, he will die!"

No one else understood what Kakashi meant. Ye Feng understood that Kai’s strong strength was not only due to his physical skills, but also the Eight Gates Ninjutsu he practiced, which played a key role in it.

When the Eight Gates of Ninjutsu are opened to the eighth gate - the Gate of Death, the caster is doomed to die.

This is something that everyone who knows how to practice the Eight Gates knows.

However, nothing is absolute. Ye Feng whispered mysteriously, "That's not necessarily true."

"What?" Kakashi didn't hear clearly.

"Nothing," Ye Feng waved his hand and said, "I'm not looking for him to learn that move from him. Besides, I'm not a ninja, so I'm not qualified to learn even if I want to. Naruto won't learn it either. His talent means he's not suitable for that kind of development."

"Why?" Naruto was a little anxious. Regardless of whether he had talent or not, he just wanted to know why he couldn't learn it.

"Quality is more important than quantity. Sometimes knowing too much is not necessarily a good thing, just like your teacher Kakashi."

Why me again? Can't you use someone else as an example? Kakashi thought in frustration.

You are right in front of me. I have a ready-made template. Who else can I use as an example if not you? At the same time, Ye Feng thought so in his heart.

Before he finished giving examples, Ye Feng went deeper and said, "Don't be fooled by the fact that your teacher Kakashi knows many ninjutsu. He is known as the 'Copy Ninja' or the 'Copy Ninja'?"

"It doesn't matter. What's the point of knowing so many ninjutsu? It's true that he can use a myriad of ninjutsu to catch his opponent off guard, but if he continues like this, without external help, he will never be able to achieve the same high achievements as his predecessors."

"Why?" This time Sasuke couldn't help but ask. For him, who was eager to improve his strength, as long as there was a way to improve his strength, he wanted to try it.

But when he heard Ye Feng say this, he felt a little scared.

"Oh, young master finally spoke? You haven't spoken for so long, I thought you were poisoned and made mute. I was wondering if Xiaoying should treat you." Ye Feng teased.

Sasuke didn't pay attention to Ye Feng's teasing. He was used to Ye Feng's nonsense. He didn't pay attention to Sakura's constant nodding. He just asked again: "Why?"

He desperately wanted to know the reason. He was afraid that he would be like Kakashi, who had learned too many things and whose strength would stagnate after reaching a certain level. That was something he didn't want to see.

He didn't know how strong that man was, but he knew that if he only had Kakashi's strength, he would not be a match for that man.

"Don't be impatient, Master. I'm about to tell you about it," Ye Feng said after taking another sip of water. "It is precisely because he knows so many things that his thinking has become somewhat rigid. When fighting with others, he will always subconsciously look for ways to break through the situation from what he knows, rather than improvising."

"You have to know that during a battle, the situation is changing all the time. You can't just mechanically apply the methods you know to it."

"It's good to be experienced, but trusting your experience too much can also become your fatal weakness. How many people think they can handle it? From my own experience, the problem at hand is a small one. I just need to do this and do this again, and I can handle it."

"People who think this way will often step into the enemy's trap step by step. I guess it's not until the moment of his death that he will figure out where the problem lies."

"Take the previous battle between Kakashi and Zabuza for example. Zabuza used the Mist Hidden Technique to block Kakashi's vision. If Zabuza hadn't been so reckless and had been showing mercy, Kakashi would have died long ago. Why did Zabuza lose so quickly in the end?"

"It was because Bai died in front of him that he was so confused that he couldn't control the rhythm of the battle."

"Bai, you didn't see it. Zabuza was like crazy at that time. If it wasn't for Cardo showing up later and them stopping the fighting, Zabuza would have turned into a mad dog and bit Kakashi to death."

"Speaking of dogs, I'm a little hungry. Kakashi, can you summon a few ninja dogs? Even just one will do. I saw that the dog lying behind Zabuza was quite fat. It should be enough for us to eat."

"Uncle shop owner, we've gotten off topic!" Naruto spoke up in time. He saw Kakashi had already taken out the kunai. If he didn't say anything, he was afraid that Kakashi and Ye Feng would start fighting.

"Oh, sorry, I can't help it, I can't help it," Ye Feng smacked his lips regretfully and returned to the topic, "Kakashi didn't have no way to break it at that time. Just like me, my vision was not affected at all in the thick fog. Kakashi could do it, and you can do it too."

"As long as you focus the chakra in your eyes, your vision will be greatly improved. Although it won't give you special abilities like the Sharingan and Byakugan, it will still allow you to see farther and have stronger vision penetration."

"Your method is not suitable for everyone," Kakashi shook his head and denied it, "Not everyone can control chakra as finely as you do."

"The eyes are one of the most vulnerable parts of the human body. If you don't take good care of them, you may end up going blind."

Ye Feng only used one sentence to make Kakashi speechless: "Your Sharingan was given to you by someone else."

Kakashi was speechless. What could he say? Ye Feng was telling the truth.

"So, Sasuke, you have to remember that all those who are not surnamed Uchiha and have Sharingan, their Sharingan was stolen," Ye Feng warned, "People like you who have special powers in your eyes cannot awaken without the blessing of special bloodline power."

"But precisely because awakening is so difficult and the eyes are so magical, the eyes of people like you are the object of many ninjas' pursuit."

"Here, let me say one more thing, be careful of the man in the village who has his right hand wrapped in bandages and his face wrapped in bandages, covering one eye."

"If that man was the one who did it himself, then the person I'm talking about is the one who directed that man to do it. He should bear the greatest responsibility for the destruction of your family."

"Who is it?" Sasuke roared, his Sharingan appeared in his eyes, staring at Ye Feng intently. Because of his furious mood, his chakra was uncontrollably radiating, and the bandages wrapped around his body were stained with blood.

There was a lot of noise coming from the nearby forest. Many small animals were disturbed by the breath released by Sasuke. They fled in all directions. Birds also chirped and flapped their wings to fly away.

"You say too much!" Kakashi held Sasuke's shoulders hard to prevent him from getting angry and doing irrational things, and said to Ye Feng.

Ye Feng didn't mind making matters worse, and added fuel to the fire, "Kakashi, your father's death is also related to him. No, in other words, your father's death was caused by him!"

'Crack', it was Kakashi's turn to break the defense, he exerted force unconsciously, but forgot that his hand was still on Sasuke's shoulder. He exerted force and made Sasuke frown.

"Uncle shop owner, the topic has gone off track again!" Naruto came out again to smooth things over. He didn't know who that person was, but he knew that he couldn't let Ye Feng continue talking. It was obvious that there was something wrong with Kakashi and Sasuke's mental state.

Ye Feng also frowned. Something was wrong. It wasn't someone else who was wrong, but himself. He seemed to be too complacent.

Is it because he has become powerful and has become arrogant? Why does he speak without restraint?

Patting his face, Ye Feng cheered up and apologized: "I'm sorry everyone, there are some problems with my mentality. After I go back, I will retreat to adjust my mentality. I will never talk too much in the future."

"Sasuke, I can't tell you who that person is. You are too weak right now. You have no chance of winning against him. Even the person you want to kill is probably not his opponent. In short, just remember that you can't believe anything that person says."

"Kakashi, I believe you have your own guesses about your father's affairs. Just wait, he will die, and it is definitely not due to old age. It is better for you not to take action. You are no match for him, especially after the Uchiha clan was destroyed."

As he was talking, Ye Feng slapped himself lightly in the face again. Damn, he had promised not to talk too much, but he accidentally said too much. He quickly changed the subject and said, "Well, do you still want to listen to my analysis?"

"Listen!" Kakashi nodded first. He understood his own situation.

He knew who Ye Feng was talking about, and he did have some guesses. Although he had no evidence, some things did not require evidence.

Besides, the water inside was too deep for him to control.

Sasuke also nodded. Indeed, his strength was still too weak. He was so weak that he had ideas but was unable to take any practical action.

However, this also strengthened his determination to gain strength.

The others also nodded. If there is a free way to improve strength, why not listen?

Everyone decided to continue listening, so Ye Feng continued: "Kakashi's strength improvement was restricted, and his Sharingan should also bear part of the blame. Good fortune and misfortune go hand in hand. It is precisely because of the Sharingan that he was given the title of 'Copy Ninja'."

"With the Sharingan, he can copy many ninjutsu. Because the Sharingan is so useful, when fighting with others, he always subconsciously wants to use the Sharingan to deal with those enemies that he can't handle."

"Over time, he developed a certain dependence on the Sharingan."

"This is both a blessing and a curse. He used the Sharingan to copy a lot of ninjutsu, and his brain also stored a lot of ninjutsu, which caused his own ninjutsu research to stagnate."

"If you don't believe me, you can ask him yourself. His Raikiri was created by him when he was your age. Over the years, Kakashi has only been constantly improving it, but no other ninjutsu has been created."

"The reason is that he knows too many ninjutsu. Thinking about how to use the copied ninjutsu better has taken up most of his time."

"Second, his Sharingan is an external object, not something he possesses. This makes it impossible for him to close his Sharingan. The Sharingan is always open, and it consumes his chakra all the time. This is also the reason why he cannot fight a protracted battle."

"So how to exert stronger combat power within a limited time has become Kakashi's daily research topic. This is why he has a more sophisticated control over chakra."

"It's the same for everyone. When learning new knowledge, you have to think clearly: Is this thing useful to you? Is learning this thing a waste of your time?"

"Naruto, you are a ninja, and you are good at ninjutsu, while Kai is good at taijutsu. If you want to practice your taijutsu to the level of Kai, you will need to spend a lot of time. This time needs to be measured in 'years'."

"One year, two years, ten years, twenty years. With your talent, I estimate it will take at least ten years. For Sasuke, it will take longer. For Sakura, it will take a little less time if she can meet that person in the future."
