The Ferryman of the Dead

One night, a mysterious man with a pale face came to the house, and the next day, Mom disappeared with him. I searched the house and only found a letter left by my mom. I couldn't accept what was in the letter. My mom told me that I had died seventeen years ago, and that I should never let those things catch me, and that if I wanted to continue to live as a dead person, I had to find my grandfather, who had no sense of humor. From then on, I embarked on a strange journey with my strange grandfather. I finally realized that my grandpa was the legendary ferryman of the dead. The mysterious Sea of Blood, the weird underground passage in the Kunlun Mountains, the legendary Houyi's kingdom of Yau Poi, and the terrifying Skeleton King in the Sea of Corpses. What's in the Qin bamboo slips left behind by my father? I have to continue to live as a dead man, I don't want to be captured by them.
