Naruto: I Give You the Sharingan

Uchiha Yun is a time traveler and comes with a system. It's just that his system is a bit special. Other systems are to strengthen oneself, while his system is to strengthen others, but it is just a single enhancement and can only give others the Sharingan. What would happen if Jiraiya activated the Sharingan? What would happen if Tsunade activated the Sharingan? What would happen if Naruto activated the Sharingan? What would happen if Danzo opened the Sharingan, what if Senju Tobirama opened the Sharingan? Uchiha Yun stood on the streets of Konoha and sighed: "This will be an era of Sharingan, and it will also be an era of the Uchiha clan. What, the Hyuga clan? Haha, let's see what pattern is in Hinata Neji's eyes first..." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
