The path of cultivating immortals is to seize the opportunity, defy the yin and yang of life and death, and master the universe. Let's see how the protagonist enters the Tao with blood by chance and gradually understands the truth of this world. (No heroine, no saint, decisive and dark story!)

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…

The protagonist is a pure mage, cold-blooded, cautious, dark and ruthless. There is no female lord throughout the whole process.

There is no heroine, no outbreak of life or death, but steady progress. There is no strong enemy everywhere. The protagonist is always a strong enemy of others.
