Naruto's strongest cheating system

Itachi and Shisui were very surprised when they heard Quan's words. You must know that even when they were four years old, they didn't learn the skill of fireball.

"Izumi, have you really mastered it?" Shisui didn't quite believe it. You must know that he has only had three days to teach Hao Huoqiu to Quan. He has learned a C-level ninjutsu in three days, and he is really a bit evil at this age.However, if Shisui knew that Quan learned how to fireball in just one day, how would he feel?
"Of course."

"Fire escape, the skill of the fireball." As he said that, Quan successfully released the technique of the fireball in front of Itachi and Zhishuimian.

Shisui and Itachi looked at me and I looked at you, both of them saw surprise in each other's eyes. Although the Hao fireball just now was not perfect, it was actually successfully released.Zhishui himself is a person who loves talents, otherwise he would not have taught Hao Huoqiu to Quan. Apart from being shocked by Quan's success, he is also sincerely happy for Quan.

"Izumi, do you plan to enter the ninja school in advance?" Zhishui asked, he already recognized Izumi's talent, so he hoped that Izumi would not waste this talent.

"No, I'd better learn from Brother Itachi and Brother Zhishui. I remember that Brother Itachi's younger brother is the same age as me. I want to go to school with him. I will protect him well then."

Just kidding, entering the ninja school early at this time is undoubtedly exposing yourself to Danzo and Sandai.

Shisui nodded, now is not a wartime, even if you enter the ninja school, you will not graduate early, and Shisui also understands that the things taught by the ninja school may not satisfy the freak Izumi.

"Well then, you can train with us. I saw you practicing shuriken before, so attack me with all your strength today and let me see your strength."

Quan was very excited when he heard Shishui's words, and it was definitely an honor to be able to fight Shisui Shisui, but Quan's excitement didn't last long until he heard the mechanical sound of the system.

"Ding, side mission, challenge Uchiha Shisui, hold it for 15 minutes in Uchiha Shisui's hands, and successfully hurt Uchiha Shisui. If the mission fails, three main mission rewards will be deducted. If the mission is successful, you will get 20 points of Uchiha Itachi's favorability, and the current favorability is 100/[-]."

"System, you bastard, that's Shisui in an instant. Even if it doesn't grow up, I can't beat it. It's okay to last for 15 minutes, but how can you let me hurt him? Itachi has already opened his eyes. The current Zhishui is at least the Sharingan of two gouyu."

"Uchiha Shisui is now Sangouyu Sharingan. By the way, if you insult this system again, I will increase the difficulty of the task, such as defeating Uchiha Shisui, or killing Uchiha Shisui." The unscrupulous system immediately expressed its dissatisfaction when Izumi cursed, and at the same time began to threaten Izumi.

Facing the threat of the system, Quan can only choose to shut up, it is impossible to hurt Zhishui jokingly, kill him?Do you use your eyes?It might be possible to say that.
