The male protagonist Lin Ji and the school's famous twin school beauties (real and fake Qianjingen) are accidentally involved in a time and space wormhole and travel to a different world in the cyber wasteland where civilization has collapsed. This place is full of biochemically modified people, out-of-control AI and extreme weather.
It starts on hell difficulty and there is no system cheat. Lin Ji relied on the logical thinking and mechanical maintenance talent of a science student to assemble the first weapon in the garbage mountain to protect the pampered sisters.
The three of them started as scavengers and used "modern business thinking" (such as milk tea marketing and Ponzi scheme memes) to establish a stronghold in an alien world with scarce resources.
Faced with the vicious stepmother's pursuit across time and space, the imprisonment of the yandere transformer, and the calculations of the green tea-type AI, Lin Ji gradually turned dark, gave up on fragile human emotions, transformed herself into a cyborg, and eventually led the mechanical army, uncovered the truth about time travel, and became a "natural disaster-level" BOSS that made even the indigenous gods tremble.
