Wasteland: I Can Create a Mechanical Legion

Also known as: I Reap Resources in Two Worlds, I Am the Creator

Early stage: [Building an enterprise + competing for resources + post-apocalypse + zombies + highly intelligent protagonist + gun girls + mech girls]

Middle stage: [Players + natural disasters + gaming + sandbox]

Lin Yao transmigrates to a wasteland with a Mechanical Calamity template. Through his own efforts, he builds up his forces and repels zombies and raiders.

He also obtains god-tier gun girls and mech girls!

In the middle stage, he tears open a rift in space and summons players from Blue Star.

In the later stages, he becomes a major force in both worlds, manipulating everything under heaven like pieces on a chessboard and rising above all others.
