Abandoned by my teammates at the start, my items can auto-upgrade.

Shen Bei had just been transported into the "National Exodus" world when his teammates treated him as a disposable pawn, pushing him to his death in despair. At the brink of hopelessness, his cheat awakened—he could upgrade any item! [Damaged Pistol LV1] → [Explosive Pistol LV3] → Strike the traitors and settle the score with blood. [Plastic Armor] → [Iron Armor] → [Nuclear-Powered Armor] → [J.A.R.V.I.S. Armor] — impenetrable, intelligent, and protective. [Clay Cannon] → [Single-Unit Artillery] → [Long-Range Laser Cannon] → [100-Meter Diameter Super Juggernaut Cannon] — one blast, one forbidden zone destroyed. [Three-Wheeled RV] → [Four-Wheeled RV] → [Truck RV] → [Flying RV] — exodus turns into a journey, natural barriers become open roads. While others scrape by in the wasteland, Shen Bei, armed with his juggernaut cannon, asks his next opponent: "Guess… how many levels can I upgrade you to?"
