Wei Zhao first stabbed Jiang Ci with a poisoned dagger, and then conspired to poison Mrs. Zhou.In order to save these two lives, Pei Yan fought side by side with King Zhuang and went to Emperor Xie Che to pray for the precious heart-protecting pill.Prince Xie Chi proposed to determine the ownership of the elixir based on the outcome of the chess game, and King Zhuang asked Wei Zhao to fight on his behalf against Pei Yan.

On the chessboard, Wei Zhao and Pei Yan each showed their talents, pressing forward step by step, and the situation was stalemate.At the same time, Jiang Ci's injury worsened rapidly, and Cui Liang was helpless and had to send Shuxia to report to Pei Yan urgently.Pei Yan was anxious and wanted to find a breakthrough in the chess game.

King Zhuang was unwilling to give up easily, so A Li came up with a plan, hoping to change the situation during the tea ceremony.In the end, Pei Yan was superior and won the chess game, and he immediately returned with the pill to save Jiang Ci.However, Wei Zhao had already understood A Li's plan and deliberately failed. He secretly arranged for Lao Liu to notify A Li and Lao He to transfer to prevent their identities from being exposed.A Li did not want to drag Wei Zhao down, so he chose to commit suicide to apologize.

It turned out that Pei Yan's mother was weak and had received a heart-protecting pill from Xie Che, but she never used it.Pei Yan's fight was actually a ploy to lure the enemy.He found out that A Li was a slave that he had brought from Yueluo City three years ago, and he was even more shocked to find that there was also a spy hiding around King Zhuang.Wei Zhao carved wooden plaques to commemorate his deceased clan members.

Pei Yan was afraid that the assassin would attack Teng Rui again, so he placed him in a separate garden and strengthened his vigilance.He asked his mother for a backup heart-protecting pill to save Jiang Ci. Jiang Ci gradually became stable after taking the medicine.Pei Yan was waiting beside him, never leaving. Although Cui Liang blamed him for putting Jiang Ci in danger, he had no choice but to capture the murderer.

Jiang Ci woke up and saw Pei Yan guarding him, and felt grateful.Pei Yan personally changed his dressing, and the relationship between the two gradually deepened.At this time, the Hou Mansion was suddenly hit by a fire. Pei Yan led the crowd to fight the fire, but he was worried about Jiang Ci's safety.After returning, Pei Yan tested Jiang Ci for clues about the assassin, but Jiang Ci deliberately concealed it.

Pei Yan speculated that the assassin might be an important official in the court, so he secretly ordered to investigate the suspicious official.In order to lure the enemy deeper, he decided to keep Jiang Ci and asked him to cooperate in acting.Jiang Ci reluctantly agreed and transformed into a maid.Shuxia took the opportunity to retaliate, but fortunately Wei Zhao secretly helped to resolve the crisis.Wei Zhao followed Jiang Ci like a shadow, constantly reminding Jiang Ci to pay attention to Teng Rui's movements.

Jiang Ci acted cautiously and used the help of his maid to obtain Bieyuan's waist card and sneak into Teng Rui's residence.Teng Rui indulged in wine and sex and didn't care about worldly affairs, so Jiang Ci recorded them one by one.Teng Rui recognized Jiang Ci as his savior, held a banquet to express his gratitude, and presented him with a jade gourd.Pei Yan was unhappy when he saw this, and practiced swordplay late at night to vent his anger. Jiang Ci accompanied him and was accidentally injured.Pei Yan delivered medicine late at night, and the two of them understood each other tacitly.After Pei Yan left, Wei Zhao appeared again and continued his surveillance duties.
