On the verge of death, the [All Things Synthesis System] awakens! Scrap iron is synthesized into a laser sword, sewage is synthesized into life liquid, and waste chips are synthesized into a super brain chip! He pretended to be a weakling, used his instinct to detect the conspiracy in the wasteland, and rescued the twin sisters Su Qingyao and Su Qingyue who were being hunted. The yandere love rival is closing in on you, the hypocrite hides his knife in his smile, mutated beasts are rampant, and shenanigans happen frequently. While Lin Che was merging gods, pretending to be pigs and eating tigers, she joined hands with her twin sisters to solve the mystery of the doomsday, falling in love on the edge of good and evil. Who said that solving a case can only rely on your brain? I, Lin Che, rely on the synthesis system to kill through the infinite wasteland and take back everything!
