Scholar in the Demon World

He, Su Jin, is a scholar, a demon, and a "flower of the dead". Jiuyu said: "Su Jin, you are the elixir for everyone in the world. If you get it, you will not grow old or die. I am the only one who has got my hands on you, but I can't live or die, and my soul is destroyed!" Su Jin said: "Fox, if one day you don't want me anymore, just train me!" Even if I die, I will die in your belly.
