Nirvana Plan

In 2157, human civilization was crushed by alien invaders. Chief Engineer Fang Yuan died in the battle, and when he opened his eyes again, he returned to 2026 - an era when everything was still too late. But he started on a hellish difficulty: he was fired from the company as a scapegoat, banned by the entire industry, and his father was seriously ill and was waiting for money to save his life. No one knows what is in his mind - it is a complete black technology tree that humans have exchanged for a hundred years of blood and tears. Photonic chips, cold fusion, space folding... He started out in a shabby warehouse and used alien-level technology to crush everything. Competitor? Dimensionality reduction attack. Blockade? Lift the table directly. This time, it's his turn to rewrite everyone's ending. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
