Xiao Beichen, the god of war, received an urgent warning letter and gave up the rite of enfeoffment in the north to return to his hometown of Jiangcheng. He wanted to save his mother who was being persecuted, and at the same time faced the situation of annulment. This wedding breakup banquet was not just a humiliation, but a trap to test him. The marriage contract concealed the relevant authority of the keykeeper, and the Zhao family was just a tool for the forces behind the scenes to come to the forefront.
Xiao Beichen tore up the marriage certificate to complete his counter-slap, and gradually unlocked clues with the help of Tang Wanshan and other insiders, and found out that his mother was chronically poisoned, and that the death of his father Xiao Zhenshan was an active choice to enter the game, not an ordinary murder. During his investigation, he learned that his lost sister Xiao Yutong was not dead. She was operating secretly in the Gray Realm under the codename "Nightingale" and had been protecting her family in the dark.
Xiao Beichen destroyed the Sihaitang and forced the Zhao family to collapse. He learned from Zhao Donglai that there were three keys, involving the marriage contract, Nightingale, and the Northern Territory. In order to uncover the secret of Shenku's authority, Xiao Beichen and Su Qingxue, who was partially aware of the inside story, went to the provincial capital as the center of the chess game.
In the provincial capital, Xiao Beichen fought against the forces of the Han family and defeated the grandmaster with one punch. He obtained the reminder object left by his sister in the underground auction house and obtained the list of various forces. In Chapter 50, the key figure behind the scenes, Gu Chengxiao, appears, pointing out that Xiao Beichen has entered the chess game set by his father. At the end, the image of the nightingale is released, and the multiple main lines officially converge.
