Delta Force: An Aggressive Ace? I'm the Rat King

Delta Force + parallel world + one heroine + sly protagonist

While all the top players are playing fierce assault gods, he chooses to become the Rat King lurking in the shadows.

Transmigrated into a life burdened by debt, he activates the "Extraction System" in a hardcore shooter that rules the world: scavenge junk for cash, eat leftovers to draw god-tier skills.

From a bottom-tier rat mocked across the internet to a ghost who terrifies the pros, he uses the most cautious tactics to topple the most glittering throne in esports.

Yang Qijia, Lao 78, and Lin Shu are all left amazed by his outrageous plays.

This isn't a story about godlike marksmanship. It's a legend of turning the tables in desperate circumstances, using wit, patience, and a System cheat to trample the entire game's ecosystem underfoot.
