After her rebirth, she went from the Commander of the Apocalyptic World to the useless second daughter of the Nian family from the upper-class society!

'Trash', 'stupid, and 'useless' were the typical labels the rich daughters of other families stuck on her.

In the past, the Host was often framed by her manipulative sister. While her stepmother tried to seize her inheritance rights, her scumbag of a father wanted her dead more than anything in the world.

Since her rebirth, Nian Yue has been settling old scores one by one. “Don't be anxious, everyone! I will slay you one by one!”

From then on, she became the top scorer, the champion racer and even the god of investment!

He was the Fu family's Ninth Young Master. He was handsome, violent, moody, and had an androgynous face. Many women flocked to him, but everyone knew that under that countenance was a devil that killed people like they were flies.

Initially, it was thought that this devil would be arrogant and aloof all his life and would never have eyes for anyone. However, everyone’s jaw dropped when they witnessed the devil trailing behind the Nian family's Second Miss, wheedling and asking for hugs!

Su Xiao is a cold-blooded young adult who’s seeking vengeance for the death of his family, yet things ended up badly for him.

As he was taking his last breaths, he heard a voice calling him from dimensions, it was a strange system reaching him, asking him if he wanted to be saved, to be Reincarnated.

He just needed to accept a contract, Su Xiao didn’t have any choice but to do so, but he didn’t know what he signed up for!!

Travelling through worlds, doing extremely dangerous missions, collecting special items, levelling up, and even killing Protagonists…

But Su Xiao wasn’t any ordinary Contractor, Su Xiao was a Hunter!

The MC crosses over to: One Piece, Tokyo Ghoul, Naruto, Fullmetal Alchemist, Attack on Titans… and Author’s Original Worlds…

Throughout this current life of mine, I will pay no attention to my past lives, nor will I seek future lives. I wish to live vigorously, to pay back debt of gratitude and fulfill duty to avenge, to defeat valiant heroes from all species, and to proudly laugh at all the Gods and Demons of the Six Path of Reincarnation!
