Extraction Shooters Are Huge! But It's Warhammer 40K!

(Warhammer 40K, extraction shooter, looting big treasures, budget run rat, sniper rat, hoarder rat.)

After a battle between the Imperial Guard and rebels, the battlefield is littered with supplies. Equipped with the Extraction System, Li Qinwu begins his career of scraping the ground clean.

A dead soldier's lasgun? Take it, it shoots tier-3 ammo.

Flak armor? Take it! That's tier-4 armor.

A fallen commissar's bolt pistol, wow! Shooting tier-5 ammo!

A destroyed Leman Russ tank, and you can actually salvage a big treasure tank battery from inside!

Bring it all back to the bottom-tier hideout! Sell it to major gang contacts, exchange it for building materials, and upgrade the hideout.

The hideout crafts master-crafted machine guns, high-output batteries, equips six sets of power armor, charges onto the battlefield to fiercely assault heretics, raises the Emperor's favor, and ascends to the Golden Throne!
