Wasteland Factory: Rebuilding Civilization from the Conveyor Belt

When Lu Chen climbed out of the emergency cabin, the back of his head still hurt. It has been a year since the Gray Tide broke out, the city has been reduced to ruins, and the air is full of putrid smell. He was thinking about how to find food when a line of words suddenly came to his mind - "The automated construction system has been activated. Offline mode. Some functions are unavailable." "What can you do?" "Basic construction. The host can use the construction gun to consume materials to build buildings instantly." "Where are the materials?" "Please collect it yourself." "How to collect it?" "Please explore on your own." ... Okay. After all, it is a system, although it is a little short of words. On the first day, he rubbed his hands on a mining machine and was rated "F- for efficiency" by the system. The next day, he picked up an Internet cafe cashier who was about to starve to death. The first thing he said was: "Brother, you are the protagonist, right?" On the third day, another mute girl who couldn't speak was picked up. Without saying a word, she smashed the gray beast's kneecap with an iron pipe. Since then, there has been a base in the wasteland with a slightly different style. While others hide from the gray beast, he builds a gun tower to fight back. While others gnaw tree bark, he lays conveyor belts and automates production lines. While others broke their heads for a sip of water, he planted potatoes under the walls and wondered how to use the metabolites of gray fungi to build a house. The gray tide is getting closer and closer, the gray beasts are getting stronger and stronger, and more and more survivors are being taken in. Lu Chen originally just wanted to survive, but later he discovered that - by accident, civilization seemed to be rebuilt.
