Time Pawn Shop - Full Level of Understanding but Afraid of Returning Every Day

I spent my life to strengthen my understanding, but unexpectedly I was seriously injured by my enemy and was on the verge of death. In order to save my life, I immediately exchanged all my time, cleared my cultivation level in an instant, and returned to the era of Milkman. Fortunately, the chosen one was passing by and mistakenly took me as a fairy fetus from heaven and carried me back to the mountain gate. Looking at his infant self, the former Demonic Master's eyes were filled with tears: "The new apprentice's facial expressions and eyes... Why are they exactly the same as that traitor?" I sucked my fingers: "Ah, ah, ah, ba?" ——Fortunately, the number has not been deleted from my memory. I just sigh that it will be completed when my life span of 100 years expires. Before I die, I spend every day practicing the art of rejuvenation: I just hope that I will not be reincarnated as a bastard in my next life. This novel and its characters are purely fictitious.
