Konoha: the God of Medicine Comes to the World, I Will Extend Hashirama's Life

Emiya Shihara, the ancient god of healing, whose body was sealed in a crystal coffin of the Senju clan and will remain immortal for thousands of years. After the battle in the Valley of the End, Senju Hashirama was seriously injured and on the verge of death, and his life was about to end. Konoha is still standing, but if the Hokage falls, peace will instantly collapse. Senju Tobirama made a crazy decision that shocked the ninja world - smashing the clan's sacred objects with his own hands, reincarnating in the filthy earth with forbidden techniques, and dragging the legendary medical god who could even revive the dead back to the human world from the underworld. However, what Tobirama didn't know was that this "compassionate" ancient saint had two SSSSS-level system tasks hidden in his body: to defeat Kaguya Otsutsuki, and to defeat Naruto Uzumaki and Sasuke Uchiha. The Samsara Eye, the Eternal Kaleidoscope, the Wood Release, the Six Paths Mode... This man arrived at the dawn of Konoha with a plan that spanned thousands of years. Everyone thought he was here to save people - but he was waiting for a chance to truly be resurrected. Continue Hashirama's life? But it's just the first step.
