Kill That Evil Summoner

Before he was twenty years old, He Zhu was a red devil known to everyone in the assassin world, the third generation of rage, the chief of the Seven Deadly Sins, and the most powerful summoner of evil spirits in history. After the age of twenty, He Zhu was a senior student at the Magic Academy, a passerby who was completely unpopular with the opposite sex, and the brother of his two younger sisters. All this change started when He Zhu picked up a girl who claimed to be a holy relic. Let the black wings bloom before the world ends. The rotten undead awakened in groups, and demons descended from hell to the world just to worship the eternal throne of God.
