My Mortal Enemy Is Actually My Teammate? Slaughtering My Way Through the Infinite World

“Either we work together to clear this level, or we die together!”

Bian Yao, a battle-hardened undercover agent, fought his way through a hail of bullets, only to be swallowed by the System at the final moment of his mission.

Yu Sheng, a genius scientist who commanded quantum technology, plunged into an unknown space after an explosion in his lab.

Two sworn enemies who should never have crossed paths were forced to struggle for survival in an “infinite instance” world.

In “Doomsday City,” zombies surrounded the city as they fought back-to-back.

In the “Time Maze,” the cycle kept restarting, and they risked their lives to break the deadlock.

In the “Mirror World,” their dark sides awakened, and they turned their blades on each other...

But as they delved deeper into the instances, they realized:

“This isn't a game at all!”

A top-secret military experiment lurked behind the System.

Every time they cleared an instance, someone died mysteriously in the real world.

And their memories were being altered bit by bit...

“Final instance,” the mechanical voice announced coldly. “Only one of you can survive.”

Bian Yao raised his gun, aiming at Yu Sheng's forehead.

Yu Sheng's fingertip hovered over the button to activate the self-destruct program.

After three seconds of silence, they suddenly turned in opposite directions, firing bullets and code into the void!

“To hell with your rules. We're flipping the table!”

[Two powerful leads + infinite instances + suspenseful mind games + high-octane battles]

When sworn enemies become each other's only allies, this infinite world is destined to be turned upside down!
