My System Is Three Thousand Years Early - Chapter 9 - 7 I’ve been exposed?

A letter to break off the engagement leads Ling Family in Tangyang to endless doom. And he, Ling Zhang, is tortured to death after his legs are cruelly broken.

A ritual gone wrong gave him the world's deadliest Class—now all he wants is blood.Zeth stole the most powerful ritual magic in the world from a mad cultist. A Class that's fueled by the blood of his enemies and human sacrifice. One that's illegal to use, punishable by gruesome death. And now that he has it, he's faced with a choice: hide away for the rest of his life from those who would hunt him down, or embrace the power, becoming the hunter to get revenge on the murderer that stole his friends' lives.For Zeth, that's no choice at all.His enemies have to die. And he plans to use every drop of blood, eldritch ritual, and demonic summoning he can to kill them.

…but it seems pretty doable.

The long night shrouds the world, and the dawn is late in coming.Evil descends upon the land, causing immense suffering to all creatures.He roams through the long night, wanders on the edge of the blade, and sways between the clouds and hell.Igniting the fire of the star soul.Since the night is long, then I shall be the lord of the night.
