After returning to Bo Qing Guan, Wen Renjing lost her memory. Lu Tingxiao decided to go to the West Country Poison Forest to get ruthless grass. Fang Xianxun found out that Wen Renjing was pretending to have amnesia, and in order to fulfill them, he left to go to the West Country without telling them. Lu Tingxiao decided to use Huihun San to transfer the poison to himself. Wen Renling saw that Zheng Lin came to pick up the plaque of the Yinshu Pavilion, and then learned that the Wannian ginseng he received before was exchanged by Liu Zhan with his Yinshu Pavilion. After Wen Renjing's situation improved, he was kidnapped by Wang Yizhi. Wang Yizhi threatened Lu Tingxiao to hand over the general's order, otherwise, Wen Renjing would be killed, and Lu Tingxiao's love was poisoned. At a critical moment, Fang Xianxun came to the rescue and joined forces with Lu Tingxiao to defeat Wang Yizhi. Wen Renjing was exhausted trying to save Lu Tingxiao and Fang Xianxun, but after they woke up, they began to fight each other.
