Chang He, who has been in the real estate industry for ten years, once traveled back to the Wude period of the Tang Dynasty and became a guard destined to be sacrificed in the Xuanwu Gate Incident. Faced with the life-and-death struggle for imperial power between the East Palace and the Prince of Qin's Palace, he did not take sides or gamble his life. He used his housekeeping skills in his previous life to formulate the detailed rules for the access control of the Xuanwu Gate, and used the pros and cons to dismantle them to persuade Li Yuan, Li Jiancheng, and Li Shimin to sign and endorse them. He only respects rules and ignores human feelings. He relies on a piece of iron law to stand firm in the turbulent court, escape the fate of a chess piece that must die, and wants to be the gatekeeper of Xuanwu Gate and the referee of the imperial power gambling game. But the strict rules also forced out a crazier conspiracy in the dark, and a killing plot against him was quietly brewing.
