Rebirth After the Doomsday: I Built It Three Hundred Meters Underground

The extremely cold apocalypse has arrived, with temperatures plummeting to minus 80 degrees. Lu Chen died on the day the safe house was breached. Neighbors broke down the door to steal food, and his ex-girlfriend led people to force him to hand over space supplies. In the end, even the fortress he built with his own hands was opened from the inside. Seven days before the end of his rebirth, Lu Chen awakened to the infinite space. In this life, he no longer trusts anyone. Selling cars, mortgaging real estate, emptying virtual currency, and cashing in everything you can. Rice, flour, grain and oil are stored in thousands of tons, and medicines, fuel, equipment, and weapons are not left behind. While others were still grabbing a bag of rice, Lu Chen had already started digging a fortress three hundred meters underground. Unlimited water source, unlimited power, intelligent central control, doomsday chariot, robot dog, drone swarm... When the neighbor knocked on the door in tears, begging him for a share of the food, Lu Chen only glanced through the surveillance camera. "I gave you a chance in my last life." "In this life, the door will never open again."
