Yan Xiaowen, the young master of the underworld, was forced to take the "Book of Life and Death" and join the other world, catch ghosts and practice, knowing life and death at a glance, and changing his destiny with a single stroke.

After eating it, I will have perfected the ghost elixir. You guys put your hands away. I will come back to the palace in a while!" "Master, it's been three times. Let's eat it later. Send the old man away. He is almost dead." "If you can't die, I'll go and come back. If you stop me, I'll kill the old man!"
