The Third Book by He Cha De Lao Si

Hauling bricks, running errands, scavenging, delivering packages... At most, a company can make you experience the hardship of a 996 work schedule. Here, you can experience 007 turned up to the max. But the great administrator says that if we restore order to the wasteland, he'll give us a set of power armor! All right, enough talk. I've got bricks to haul!

Chu Guang transmigrates to a wasteland world and discovers that he's unlocked a shelter System that lets him summon creatures called "players" from the world he came from. From that day on, the entire wasteland gets weird.
