The Mortal Medical Emperor's Story of Cultivation into Immortality

I am a mortal with no chance of cultivating immortality, but I relied on my own original medical skills to develop the Rebirth Pill. After surviving for thousands of years, I finally managed to cultivate a peerless Immortal Emperor. I wanted to pass on my medical skills to him, but instead I pushed myself into a dead end. You traitor, how dare you do this! When I come back from rebirth, I will take revenge! In this life, I was reborn in the body of a boy with forbidden meridians, but it still fulfilled my dream of cultivating immortality... This novel and its characters are purely fictitious.
