I'm an Uncle in the Delta

The 42-year-old unemployed project manager Lao Hao accidentally entered "Operation Delta". While all the masters in the server were trying to kill people with their quick hands, this "construction site man" changed his fate with three rounds of bullets and a set of "Safety Production Manual". He refused to show off his operations, specialized in fixing various system bugs, and turned the chicken battlefield into a construction site. Young people all said: "Don't ask, just ask, Uncle Hao is right!"
