Pocket Space Sign-In: Farming in the Apocalypse

The protagonist traveled through time and became a child, and his IQ also dropped. When the zombie wave comes, you can enter the space inside the house and see outside. You can also occupy the owner's house and go up to the roof to see the distance. Wait for a few days in space to wait for the zombie tide to pass, then go out and clear out the zombies around you.

Just my personal feeling, you can say that there is space, but you shouldn't have brought your sister into the space from the beginning. They are both adults, and you still traveled through time, so you don't have any sense of guarding against others?

The Lin family's parents were too partial and went to the Pacific Ocean.

I saw a label saying no cp, does that mean there is no male protagonist?
