My Doomsday Multifunctional Base

When he woke up, the world had become a post-apocalyptic survival situation. Huang Yan accidentally got a system that could create various items and upgrade them. Earn survival points every day based on the level of the shelter, collect materials, upgrade tanks, and transform the base. The last days are difficult, but Huangyan is living a carefree life. Despite the swarms of zombies outside and the bad weather, Huangyan can eat big meals, use air conditioning when it's hot, and use floor heating when it's cold, and eat, sleep, and fight zombies every day.
