Doomsday: I Can Upgrade Anything

Lin Chen wakes up to discover that he has transmigrated to a post-apocalyptic world.

He thought he would have to struggle to survive in the wasteland, but unexpectedly, he gets a System too!

Best of all, his System can upgrade things with a single click.

As long as he provides enough raw materials and crystals, it can complete the upgrades!

A kitchen knife and steel become a fine-steel machete or a blood-red longsword.

Rebar and cement become defensive walls.

Cement and cannons become basic gun turrets, laser turrets, and electromagnetic turrets.

An ordinary car and an automatic defense system become a post-apocalyptic battle vehicle.

An automatic defense system, a full-performance mechanical apparatus, and a biological intelligence control system become a doomsday mech.

While others are still struggling to fend off a zombie siege, Lin Chen has already built his own mech army! He takes the fight to the zombies and hunts them down!
