Siheyuan: Security Chief, suppressing the whole courtyard

Once upon a time, Li Meng became one of the many refugees who fled to the city of Beijing. He fainted in the alley due to hunger and cold, but was fortunately picked up by an ugly girl who passed by and became her son-in-law.
Unexpectedly, this is a world full of beasts. With the help of the system, Li Meng lived a stable life in the courtyard. By chance, he started as a temporary worker and gradually became the head of the security department to suppress the beasts in the courtyard.
Of course, there are also trivial matters. The scenes of ordinary people in the market unfold.
