Chen Sanshu is the last generation of tombkeepers in Qing'an Village.
Before he died, he told his grandson Chen Zhao that there was a real power buried under his ancestral grave. His spells could communicate with ghosts and gods, and his elixirs could revive the dead.
Chen Zhao thought it was a legend until he found a longevity charm in the cellar of his old house.
That night, a man who called himself "Yin Cha" came to the door.
"You can't keep this talisman," the man stared at him, his eyes full of fear, "something will happen."
But when Chen Zhao woke up the next day, he found a note on his pillow:
"Don't believe him. - Your great-grandfather Liu."
