Space Awakening: Revenge Starts by Taking over the Supermarket

Land for 300 million, contract for 60 million. Revenge was avenged, but my father would never be able to live again. He only has a space invisible to others, where he can hold supplies, weapons, and people's hearts. I wanted to stock up on enough supplies to live a stable life. But a natural disaster came, killing more than 80% of the world, and the order was shattered into powder. Since God has not given him a way out. Then he would let everyone live according to his rules.
