Ye Tianji, the Sect Master of the Heavenly Mystery Sect—the pinnacle of the cultivation world—was on the verge of ascending to immortality. However, he met a tragic end after being betrayed by Shuang'er, a person he considered a trusted companion. When Tianji awoke, he found himself reincarnated as a modern-day university student named Raisei Tojo. Though the foolish Raisei was mocked by those around him, Tianji discovered that a poison needle implanted in his brain was the cause and promptly removed it. Through his interactions with Kasumi, his foster sister who had devotedly supported Raisei, Tianji decided to live his new life in modern Japan. He begins by delivering a heavy hammer of justice to those who had belittled Raisei. The pinnacle of the cultivation world, Ye Tianji, is now setting his plans in motion in modern society!
