The Necromancer Wants to Cultivate Immortality Too

Luci was a necromancer. After a forbidden technique backfired, he transmigrated into a book, becoming one of the male lead's lackeys. He was also forcibly bound to a System that tasked him with redeeming a darkened, miserable powerhouse.

His redemption target was the male lead of the book.

When Luci arrived, the male lead had just suffered the slaughter of his entire family. He was swearing over their bodies that he would find the culprit and take revenge.

Lackey A: Young master, my knife will help you!

Lackey B: And my sword!

Luci: And your dead great-aunt, great-uncle, and all the rest of your relatives!

The male lead slowly raised his eyes: ?

The next day, the male lead's enemies came to finish the job before he could grow into a threat.

Lackey A: Young master, look out!

Lackey B: Young master, run!

Luci waved his wand: Die!

The enemies: dead.

The male lead's eyes shook: ??

Later, at the Immortal Sect Tournament, Luci slaughtered his way through the major sects, showing them what a necromantic disaster looked like.

The male lead's pupils quaked: ????

Later, Luci discovered that the male lead, who was supposed to become a dark, miserable powerhouse, had turned into a silly, sweet-natured guy thanks to his redemption.

* The underworld is empty, Luci is in the human world.

* You teach me cultivation, I teach you magic. We both have a bright future.
