A Natural Disaster Is Coming! I Am Learning to Cultivate Immortality in the Last Days

The food harvesting in the early stage is very good, and it is okay to recruit people on the same floor, but why do you have to recruit a half-mother? I feel that the protagonist is anxious, eager to expose his own space and ability. Who can be trusted in the end of the world except parents, who has experience in the previous life, why not be stable? Many post-apocalyptic novels are like this. It's exciting to stock up in the early stage, but later in the evacuation period, I rush to tell everyone that I have space.
