Zhixuan, a 67-year-old pharmacology professor, died suddenly in his study while staying up late studying a fragment of a Song Dynasty scroll.
When he opened his eyes again, he became a dying old man dragon, lying in the heavy rain on the mountain behind the Damu Research Institute. Next to him was a little boy holding him and crying - five-year-old Xiaozhi.
It took him ten years to teach a reckless child into a teenager who "looks for ten seconds before rushing"; he spent a lifetime of pharmacology skills to dig out bit by bit the ancient magic potion sequences buried in this world.
In this life, he is not the protagonist. He's a grandpa.
