Xie Yi Nagi's performance

Nagi's performance is: hiding in the crowd with Sasuke. Nagi, the pupil technique used in wartime, is very expensive for chakra. After being used for a period of time, it must be released for a period of time to restore chakra; Because of Nagi's reset function, any injury suffered by the performer, including death, will be reset within the effective range of the performer, while chakra can't.

The time that each sharingan can use is determined by personal ability, and the duration is also different. After using it, this eye can no longer be opened. According to Tuotu, Tuanzang's right hand was an experiment made by orochimaru to improve his service time. Nagi with soil can last for 5 minutes, but each sharingan in the group can only last for 1 minute.

In the pupil surgery of Neiguang family, the evil Nagi is forbidden, so there is another pupil surgery in Neiguang family of Huo Ying-Shalingen.

Extended data:

Xie Yi Nagi's function is to record the performer's own state with sharingan at the moment when Ninjutsu is started, and then any injury suffered by the performer, even the death of the performer, can be physically restored to the state recorded by sharingan within the effective time of operation.

The basis of launching evil Nagi is the kaleidoscope sharingan owned by the Neibo family. It is based on everything that Ootutuki Hagoromo used when he created bijuu.

Nagi's sharingan will be permanently blind, but according to Uchihiro Shoko Asahara's situation, the eternal kaleidoscope sharingan after blindness may regain its vision after evolving into a round eye.
