[False mechanics, lacking resources, are reduced to living in black households. [A real mechanic, the machine is an army, and he holds power in troubled times. Li Fei traveled to the waste planet of interstellar resources. Fortunately, he was taken in by the owner of the maintenance station, but his future was bleak because of his status as a gangster. Until he awakened to the two-way fixed-point teleportation array, he discovered that the other end was actually a post-apocalyptic wasteland where monsters were rampant - a land of disaster, which was also his treasure trove of opportunities! When the mechanic's path is bound to the double door, the survival plan is completely rewritten: Learn knowledge, accumulate resources, practice skills in the interstellar world, and build a solid mechanical foundation. Gain experience in the apocalyptic wasteland, hunt for crystal cores, clear out zombies, and hoard massive supplies. While other people's mechanics repair junk, his mechanic summons an army! Psychic mechas open the way, automatic robots clear the way, and heavy firepower mechanical arrays cover it. One person is an army! From a black man in the wilderness maintenance station to a mechanical overlord spanning two worlds, Li Fei used steel and cannonballs to create his own legend of military garrison between the end of the world and the interstellar world! (Double portal + mechanic + apocalyptic survival + interstellar adventure + mechanical army)
