Siheyuan: the Era of Dominance Begins from the Security Department

As soon as I was reborn in the courtyard, I found out that my father was dead. His qualifications to take over were forcibly snatched away by the factory leaders. The three elders in the courtyard also wanted to take the opportunity to occupy a room in his house. Since you are heartless, don't blame me for being unrighteous. So he turned around and joined the security department where he could be equipped with a gun. I won't talk nonsense to anyone who dares to mess with me. It just depends on whether your mouth is tough or my bullet is tough! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
