Quick Transmigration: The Cannon Fodder Rises

Bai Zhixia was the Child of Destiny in the original world. But some world-hoppers changed the course of events, framed Bai Zhixia as a traitor to the empire, and ultimately had their spaceship blown to pieces by a laser cannon, killing them.

After death, Bai Zhixia was bound to System 777 and sent to help the Child of Destiny in the original world, restoring it to normal. Once world-hoppers arrive, the Child of Destiny is targeted and turned into a stepping stone for them, commonly known as cannon fodder.
