Versatile Mage: Lord of the Abyss, but Tyrant of Darkness

Ye Yu traveled to the world of a full-time mage. He became Tang Yue's unrelated nephew. After awakening magic in Tianlan Magic High School. His pupils were slit with scarlet vertical pupils. The murmur of the abyss sounded in my ears. [The protection of the Tyrant of the Abyss has been activated] [Authority 1: Shadow Taboo, master the Dark Abyss of Eternal Night (needs to be gradually unlocked), completely immune to shadow attacks and space imprisonment] [Authority 2: Assimilate dark attribute creatures into dependents, and can temporarily open abyss rifts to summon abyss servants] [Authority Three: Master the entire system: obtain all magic systems including elemental system, white magic, black magic, dimensional magic, etc.] Three years later, he swallowed the remnant soul of the fallen angel and awakened the final form of the demon system. When the black mist covers the sky, when the curse tears the earth apart, I step out from the abyss and bring thousands of evils and filth to overthrow the world! ... Standing before you is the tyrant master of the abyss of eternal night, the usurper of the kingdom of the dead, and the curtain raiser of Ragnarok!
