Rebirth at the End of the World: My Mecha AI Comes from the End Game

Lin Jianwei died in the remains of the black mecha. Before he died, he heard his mecha AI box say "cannot be saved" for the first time in the cockpit. The next second, a person with the authority key opened the last door of Heijia. When he opened his eyes again, he returned to the night before the alarm sounded on the east wall of the safe zone. My sister is still alive, my brother is not dead, and the black mecha in the scrap warehouse is just a pile of scrap metal. This time, he built the black armor in advance, awakened the small box in advance, and reversed the death nodes again and again in the tide of zombies, mutant beasts, mechanical legions, and safe zone wars.
