Deep in the palace, in the dungeon of the palace gate, a group of brides including Yun Weishan, Shangguan Qian, and the fourth girl of Song Dynasty were mysteriously imprisoned.This incident caused Gong Ziyu to be deeply worried. He decided to go to Gong Huanyu and intercede with Zhibian, hoping to change their fate.

Although the decision to hold the sword gave these brides a chance of survival, he still decided to use palace poison to torture them.Gong Ziyu knew the power of this poison, so he conspired with Jin Fan to sneak into the dungeon and prepare to lead the brides to escape from the secret passage of the palace gate to save them from dire straits.

However, on the way to escape, Yun Weishan questioned Gong Ziyu's motives.When she argued with him, she was almost discovered by the patrolling guards.Gong Ziyu cleverly resolved the crisis.However, the crisis was not completely resolved. When they came to the door of the secret passage, Gong Yuanzheng suddenly appeared and blocked their way.

In order to protect the brides, Gong Ziyu and Gong Yuanzheng started a fierce fight.During the fight, Gong Ziyu finally revealed the truth.It turned out that he planned to use the “secret escape” strategy to lure out the Wufeng assassin.Amidst this mistake, Gong Yuanzheng's poisonous hidden weapon unexpectedly revealed the true identity of Wufeng assassin Zheng Nanyi, who was then subdued by Gong Huanyu who arrived in time.

Gong Ziyu originally thought that he would be praised by his father for catching the Wufeng assassin, but he found out the next day that it was all part of Gong Hongyu's plan.Gong Hongyu had long expected that Gong Ziyu would take such action, so he used his plan and waited for the assassin to show up.Instead of gaining his father's trust, Gong Ziyu's strategy was reprimanded, which made the already estranged relationship between him and his father even worse.

On the other hand, although the assassin has been captured, Yun Weishan and others entered the bride selection process as scheduled.In various evaluations, Yun Weishan showed outstanding talent and charm and received the highest evaluation.
