Hell's Handbook - Chapter 29: Black Versus White

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Name: [Art Tavel (Zhuang Zhou)]

Occupation: [Demon Warlock]

Class: [1]

Bloodline: [Abyss (0.03%), Human (94.97%), Darkness (5%)]

The descendants of the Tavel family, the bloodline of demon warlocks that had declined, had another “dark” bloodline after the arrival of Zhuang Zhou.

With this bloodline, he can summon monsters from the dark world.

The first thing he thought of was not to drive the summons to help fight, but to wonder if the equipment of the dark world would explode after the summons died?
