I’m a Sword Immortal, and the Succubus School Belle Came to Me to Be My Scabbard

Apocalyptic disasters descend, with zombies and monsters running rampant. Humanity awakens and changes careers to establish a new world order. Xie Ming has been in this world for three years since transmigrating here. Once a genius, he awakened only an ordinary D-rank Swordsman class. Fortunately, a System arrives soon after. Everyone's class is fixed upon awakening, but his can keep evolving, and each evolution comes with bonus talent traits. Swordsman, Swordmaster, Sword Lord, Sword Emperor, Sword God, and finally, the Red Dust Sword Immortal. When the beast tide hits, he swings his sword from high above the heavens, annihilating billions of lives. He thought he was about to reach the pinnacle of life, but his girlfriend's betrayal dealt him a crushing blow. Just then, the campus belle, who had awakened the SSS-rank Succubus class, came to comfort him. “My name is Bai Lianyue. I was once a witch in one of the apocalypse's forbidden zones. Not long ago, I was reborn in the body of a girl who looks exactly like me. “That very day, I met the man who ruined my life. Ten years from now, he storms into the forbidden zone and insists on hunting me down, which ultimately leaves me lost in its depths. “Now that I've transmigrated ten years into the past and met him at eighteen, the best thing to do would be to stab him to death. But there's something strange about this guy.” The witch Bai Lianyue watched as a portal suddenly appeared beside Xie Ming. Countless swords flew out and killed a large swarm of zombies. Her expression froze. This can't be right. Wasn't he supposed to have awakened as a Swordsman?
