In a Time of Chaos and Demons, Fifty-Year-Old Guards Guard Their Homes.

Traveling to a world where monsters are rampant, Cheng Yuan still lives a peaceful life in his previous life. Thirty years of clocking in to work every day gave him a strong sense of class and he also received numerous system rewards. Security, security, to protect the peace of the area. I, Old Man Cheng, am lifting the sky pole in the Hope Community. This place is the eternal holy land of the human race.
