Shin Uchiha thought about it and decided to tell Kakashi that the Sharingan owned by Kakashi is Mangekyō Sharingan, because, Even if he doesn't say it, in a few years, when Sharingan and Kakashi are almost running in, Kakashi will discover the secret of Sharingan.
He wanted to see if Kakashi had discovered the secret of Sharingan a few years in advance. He was looking forward to the subsequent plot. Anyway, the world had already made him a mess, and it was no less than this. Moreover, he also wanted to know, If Kakashi is allowed to master the Dōjutsu--Kamui of Sharingan skillfully, can Obito Uchiha be pulled out from behind the scenes in advance?
Shin Uchiha Thinking of this, I am also full of expectations for future changes.
Then, Shin Uchiha said to Kakashi with a serious face, "Senior Kakashi, you must have felt it too. The Sharingan in your body may be because you don't have in your body. Because of the Uchiha bloodline, it cannot be turned off. It consumes your Chakra all the time, which indirectly causes your strength to increase very slowly, and also reduces your Chakra. When you encounter more difficult enemies, you will be very passive."
After Shin Uchiha finished speaking, he looked straight at Kakashi: "If you still insist on keeping this Sharingan, it will have a great impact on your future. The probability of you becoming a strong Kage Level will be very low in the future, and even if you enter Kage Level, you will still be at the bottom."
When Kakashi heard Shin Uchiha's words, he closed his eyes in pain. Even though he was ready, facing this cruel reality, it was still a little hard to accept. After all, becoming a strong man is what everyone in this Shinobi World aspires to. and pursue things, and he has to make a choice here, whether to keep the relic of Obito Uchiha, which can no longer improve his strength, or to give up this Sharingan, pick up the Hatake Swordsmanship that he is good at, and go back to the powerful path of pursuing strength.
Kakashi was silent for a while, then raised his hand to cover his Sharingan, and said in a hoarse but firm voice, "I chose to keep this Sharingan that Obito left for me. I don't believe that this Sharingan alone will prevent me from improving my strength in the future. Even if I can't improve and cut off my path to becoming stronger, I won't regret it."
Shin Uchiha knew that Kakashi would choose this path. He nodded with satisfaction and said with a smile in his voice, "I knew you would choose this path. In fact, it is not so absolute. This Sharingan is just a stepping stone for you to become stronger, not a roadblock. As long as you cheer up and stop being decadent, you can still defeat it."
Then, Shin Uchiha's face also became serious. "Then, I will tell you the biggest secret of this Sharingan now. It is possible that through this secret, you will find a path that suits you and become stronger again."
Shin Uchiha saw that Kakashi's face became serious, so he opened his own Mangekyō Sharingan towards Kakashi. Of course, he only opened it and did not use it on Kakashi.
When Kakashi saw Shin Uchiha opening his Mangekyō Sharingan again, his body became alert, but he remembered that he had been knocked down by his Mangekyō Sharingan and Genjutsu before. He quickly turned his face in another direction. He immediately became nervous and took a defensive posture with Kunai in his hand.
Seeing Kakashi's reaction, Shin Uchiha chuckled and comforted him in a soft voice, "Senior Kakashi, don't be nervous. I really have no ill intentions towards you. If I wanted to do anything to you, you would have no chance to stand here."
Of course Kakashi knew that what Shin Uchiha said was right, but he couldn't accept that he had no ability to resist and was knocked down by Shin Uchiha. Kakashi reached out and took his Forehead Protector raised his head, revealing his Sharingan. Then, Kakashi turned his head, but still did not dare to look at Shin Uchiha. Instead, he looked down at his feet.
After all this was done, Kakashi said, "Shin Uchiha, I know you are Uchiha Clan's genius. Although you are younger than me, you have already awakened Mangekyō Sharingan, even if your strength is Konoha, you are still among the top ones. I am far from your opponent, but you should not open your Mangekyō Sharingan for no reason. If you do this, it will be difficult for me not to doubt your intentions."
Shin Uchiha saw that Kakashi was avoiding his Mangekyō Sharingan like a snake, and chuckled, "It seems that senior Kakashi is more afraid of my Mangekyō Sharingan? I wonder how much senior Kakashi knows about our Uchiha Clan's Mangekyō Sharingan?"
Kakashi still put his eyes on Shin Uchiha's feet, not daring to meet his eyes. Knowing that Shin Uchiha didn't have much hostility towards him, although he still didn't dare to let down his guard, he breathed a sigh of relief and answered Said: "Actually, I didn't know much about it before. I only knew that Uchiha, Sharingan, One-Tomoe to Three Tomoe, but since that time you used outside the village Susanoo, kill Danzo and the others with one blow. I learned from Lord Third Hokage that your Uchiha Clan's Sharingan has a higher form, called Mangekyō Sharingan, it's just that Mangekyō Sharingan seems to be difficult to awaken. Even in the Uchiha Clan, it hasn't appeared for many years. And the Susanoo you used that day was the ability of Mangekyō Sharingan."
Shin Uchiha nodded unconsciously when he heard Kakashi's words. He did not expect that Kakashi already knew Mangekyō Sharingan so thoroughly.
Shin Uchiha doesn't know, but what Kakashi knows is all the information Second Hokage Tobirama Senju left to Third Hokage. Since Third Hokage arranged Shin Uchiha to Kakashi, of course he will also tell Kakashi the relevant Intelligence.
Shin Uchiha waited for Kakashi to finish speaking, and praised, "I didn't expect that you actually know Sharingan better than most of our Uchiha Clan clan members. Obito Uchiha's Sharingan is in your body, so it doesn't mean it was buried."
Shin Uchiha paused, then asked, "Then do you know why I opened my Mangekyō Sharingan in front of you for no reason?"
Kakashi was also a little confused and shook his head. "I don't know why you opened Mangekyō Sharingan. After all, Mangekyō Sharingan is your Uchiha Clan's ultimate Kekkei Genkai, opening and using it should cost a lot of Chakra. Since you are not hostile to me and are not going to attack me, I don't know why?"
No matter how big Kakashi's imagination was, he never imagined that the Sharingan he owned was not an ordinary Three-Tomoe Sharingan, but a Mangekyō Sharingan. Even in the Uchiha Clan, it was an extremely precious treasure.
