I Picked up the Future That Saved Humanity Seven Times

In a junkyard in 2077, I accidentally picked up a military-grade neural implant. Rely on it to repair abandoned mechas, win the black market competition, and earn your first pot of gold. Ten years later, I stood in front of the 100-story floor-to-ceiling window, overlooking the technology empire I created. At the celebration banquet, my fiancée Su Ying caressed the diamond-shaped interface of the same style as mine: "You know? This implant comes from a parallel world." "Human civilization has been destroyed seven times, and we are undergoing the eighth reincarnation." "And this time, I came back with quantum battery technology, just to prevent mankind from dying again."
