I am the Lord of the Underworld

Story:

Mutation strikes, the world is overturned, and after a hundred years, humanity enters the era of universal job change. Chai Yu starts with an awakening of an SSS-level talent – the Apostle of the Underworld. Infinite undead, skills multiplied by a hundred, mental control – watch as Chai Yu sits on the high platform of ten thousand bones, deciding life and death with a wave of his finger. Three years later, the Void Clan invades the Blue Star. Chai Yu opens his eyes and says, “Hmph, mere aliens, easily exterminated with a flick of my hand!” In an instant, the Kingdom of Death descends, and billions of natural disasters engulf the void.
