Villain: I Become the System Across the Heavens

Ye Ye unexpectedly encounters a System, but thinks he's fallen victim to a new kind of scam.

He never expected to crash the System outright. After waking up on the brink of death, he fuses with it.

From then on, he takes the form of a System and travels through the Myriad Worlds, stealing the origins of those worlds to survive.

From then on, he helps his Hosts:

Pummeling urban little miracle doctors and tearing into historical fiction plagiarists!

Tearing apart fake good-for-nothings who have had their engagements called off, and tormenting genius beast tamers!

The protagonists: Ah!! What gives you the right to be so badass?

Ye Ye: Do you know what your Systems call me?

The protagonists: What?

The Systems: Grandpa!

Ye Ye: That's right, you can always count on the Ye Ye brand System!
