My Master Isn't Human

Ever since he was old enough to remember, the young disciple knew his master was a little different from other people. Young disciple: Master, why don't you eat? Man: Because I'm not human. Young disciple: Master, why don't you take care of me yourself? Man: Because I'm not human. Young disciple: Master, why did you give me a knife? Man: Come on, stab me to death, disciple! This is the story of an undead zombie king who transmigrates and takes in a disciple in the hopes of getting himself killed! The recipient is unbelievably powerful! Mainly cultivation, sweet, doting, and with an older shou and younger gong!!! ★ Disciple gong, master shou, younger gong! ★ The prologue sets up the shou's background. Most of the story is told from the gong's perspective, but it doesn't focus solely on him. Please keep that in mind before reading. Thank you! Theme:
