Apocalyptic Mechanical Chariot

The failure of a mission brought Han Feng back to before the apocalypse began.And the mechanical core, the mission item he obtained after a narrow escape, actually appeared in his mind.With the mechanical core, the Unimog RV can actually resist cruise missiles!An RV with a mechanical core can evolve independently! This unscientific!With a huge advantage, Han Feng relied on the mechanical core in his mind to smelt countless machines, and in this apocalyptic world full of suffering, he embarked on a completely different path from his previous life.
