Apocalypse: My Safe House Connects to Parallel Universes

Lin Ji participated in an absolutely confidential "consciousness uploading" experiment. No one knew that when the experiment declared "failed", his consciousness had actually traveled to a parallel universe engulfed by zombies and extreme cold, and he struggled to survive there for a full ten years. He returned with ten years of combat experience, full-level survival skills, and the world's highest technological crystallization - [Quantum Terminal]. At this time, the countdown to the end of this world is: 07:59:59. The first thing: kill the doctor who wanted to euthanize him and evacuate the laboratory. The second thing: go to the unfinished underground air-raid shelter on the outskirts of the city, start "material reorganization" and create an absolute restricted area. The third thing: watching the end come. While humans were still afraid of mutated zombies, Lin Ji had already opened a portal to other parallel apocalypses. "Lack of energy? Go to [Wasteland World] to dismantle two nuclear reactors and come back." "Lack of weapons? Go to [Cyber World] to purchase a batch of laser cannons." Walking in thousands of apocalyptic worlds, and then easily turning the main world into a private back garden.
