Wolf of the Blood Moon: A Blood Magic - Chapter 12Book 6:

Traversing worlds with the Immortal Sword slaying demons, it was not until a monkey who claimed to be the Monkey King appeared before Lu Yu that he realized he had come to the world of Journey to the West. Striving for supremacy along the Human Path, the secrets of Journey to the West unrevealed, cutting off heaven and earth, the Three Realms were isolated.

Once, because of a pair of purple eyes he was scorned. He is a wangye known across the land, cold and bloodthirsty, looking disdainfully upon the world.

Loose cultivator Shi Lang gradually found himself in the realm of invincibility. However, when he finally tried to ascend to the higher realm, the spirit of the world was nearly exhausted.

So, between his ascension to a new world or the well-being of his home, he chose the latter and sacrificed his life to save the world.

Nobody knew what he gave up for the world, and he told no one.

Although his sacrifice had gone unsung, there was still someone who witnessed everything. A treasured artifact he carried on his body preserved his soul and let it escape a tragic end.

Eons passed.

The human race stepped out from the age of cultivation into an age of stellar conquest.

The spirit energy in the world was now scarce, but humans found other means to excel.

In this highly-advanced time, Shi Lang's soul has found a chance to be reborn.

What happens when an ancient cultivator that neared the level of a deity before his first death gets a second chance at life in the space age?

Daytime belongs to the human world, while Deceit Night returns to the netherworld.Since the arrival of the sinister night, demons and evil spirits have brought disaster to humanity, and generations of our ancestors have struggled to survive.This blade of mine can eliminate evil, slay demons, defeat wickedness, exterminate devils, destroy evil!From now on, nighttime shall be like daytime!
