On a winter morning, Gong Ziyu woke up from his sleep in the Wanhua Tower in the Old Chen Valley.The sun shines through the window lattice and shines on his face, bringing a touch of warmth.The girl in purple who was waiting for him to get up gently urged him, reminding him that today was the big day for marrying the bride at the palace gate, so he couldn't delay it.

At the same time, in Lixi Town outside Jiuchen Valley, in an ordinary house, the mother and daughter were saying goodbye.The mother was arranging her daughter's wedding dress, her eyes full of reluctance.Suddenly, two assassins dressed in black and armed with sharp swords broke into the house and instantly knocked out the mother and daughter.

Soon, one of the assassins put on the bride's wedding dress. She was Wu Feng's elite Yun Weishang.The purpose of her trip was to sneak into the palace and become the wife of Gong Huanyu, the young master of the palace, in order to obtain the palace's confidential information.

Gong Ziyu and his guard Jin Fan returned to the palace gate in a carriage, talking about today's happy events along the way.However, their carriage was hit by a drug store owner who was riding on horseback from outside Old Dust Valley.The drug store owner was seriously injured. He told Gong Ziyu that their outpost was raided by Wu Feng, and he overheard Wu Feng's plan by feigning death. Among the brides sent into the palace tonight, there was oneIt's an assassin.

Gong Ziyu was shocked when he heard the news, and immediately informed Gong Hongyu and the young master Gong Huanyu of the news.However, they did not know that this news was actually leaked by Wu Feng on purpose.In order to ensure the safety of other spies who sneaked into the palace gate, Wu Feng deliberately leaked the news and sacrificed a spy as bait.

Gong Hongyu, the swordsman, was experienced. After hearing the news, he decisively decided to kill all the brides to avoid future troubles.However, Gong Ziyu did not want to see innocent people being killed indiscriminately, and he had a fierce conflict with his father.

During this conflict, Gong Ziyu began to doubt Wu Feng's true purpose, and Yun Weishan's identity gradually attracted his attention.
