Coming to the ninja world inexplicably, Hongji inspired to become a medical ninja. Starting as a trainee at Konoha Hospital, he gradually became a great medical ninja surpassing Tsunade, the Fifth Hokage.
But is this really the case?
How is that possible!
What to do when facing the captain and teammates who don't like it? Of course, send them to see the Sage of Six Paths.
In the ninja world, if you don't have the ability to directly avoid the infinite Tsukuyomi, then no matter how strong you become, you can't seem to escape the conspiracy of Black Zetsu.
And if you want not to be affected by the Infinite Tsukuyomi, you need the Samsara Eye that overrides the Infinite Tsukuyomi.
Whether it is to capture or open the reincarnation eye, medical ninjutsu is indispensable.
And this is the reason why Hongji is a good old man in Konoha Hospital!
