I, the Necromancer, Part-Time Transmigration

[Return the stranded souls! It will give you strength back! Qi Tu, who was fired, unsubscribed from the weekly magazine he had been reading for many years, but on Monday a package was still sent to the original address—— A blood-red book with a mouth. It says that it is a document of the dead; it says that magic exists in this world, using souls or phantoms as fuel; it says that by returning the soul stranded on this shore, his soul will be sublimated; it says that after experiencing the shadow world and the baptism of blood, he will eventually be crowned king... "In other words," Qi Tu concluded for his pie: "Can you find me a new job as a necromancer?" "It's pretty much the same, with similar functions - it's the savior."
