Episode 30 recap: Pan Yue accused Guan Xue of being a spy.

Guan Xue and Chief Qian Ye questioned Song Zhuo Wen about the pursuit, and Song Zhuo Wen blamed all the mistakes on Hu Bin. Dr. Xiao Dao went to see Chief Qian Ye, hoping to increase the budget for the epidemic prevention and water supply department. He believed that although some people escaped, the experiment itself was a success, but Chief Qian Ye did not agree.

Ding Peng went to the information room to check the data that Song Zhuo Wen had checked a couple of days ago, and afterwards specifically asked about Song Zhuo Wen's last visit to the hospital. Ding Peng went to the hospital to inform Pan Yue secretly. Pan Yue was very anxious to catch Song Zhuo Wen and find some leverage against him.

Chief Qian Ye instructed someone to prepare a body, as not all the escaped prisoners from the epidemic prevention and water supply department could be captured, so it would be better to find a replacement. Pan Yue called Guan Xue to anonymously report that there was a spy in the Special Service Division. Pan Yue also claimed that Song Zhuo Wen was the mastermind behind everything. Guan Xue dealt with the call while instructing someone to investigate it. Pan Yue used a cup to disguise his voice, but Guan Xue quickly recognized his identity and Pan Yue hung up the phone without saying a word.

Xie Yue heard Guan Xue's secret signal, which meant that Guan Xue definitely had new arrangements. Xie Yue became very nervous. As soon as Xie Yue left, a male classmate who was tailing him appeared. Xie Yue followed him to a hotel, where he said that someone else would come later to join him in tracking Xie Yue. Xie Yue slapped him and desperately knocked on the door for help, but the door was already locked and no one responded no matter how hard he knocked.

However, Guan Xue's people arrived quickly, and Xie Yue felt relieved by Guan Xue's presence. She handed Xie Yue a chair leg and told her not to hit her head with it.

After surviving the ordeal, Xie Yue went crazy and beat him mercilessly, while outside the door, Guan Xue thought about her own uncle and how she had personally killed him.

On the way back, Guan Xue absentmindedly played with Xie Yue's hair and asked about Song Zhuo Wen's usual behavior and any changes that had occurred. Xie Yue mentioned that Song Zhuo Wen had been experiencing insomnia recently and could hear him tossing and turning at night. Guan Xue's eyes widened in response, but Xie Yue quickly smiled, knowing that Guan Xue had been listening from behind the door.

Guan Xue asked Xie Yue to investigate Song Zhuo Wen's stomach condition and take note of the quantity of his medication. Lu Jianfei wouldn't bother Xie Yue again; her fierce demeanor just now reminded her of her past self. Once Xie Yue returned home, she immediately counted the number of stomach pills, but Song Zhuo Wen had already been cautious.

Hu Bin brought a pot of deer tendon to Guan Xue's office, but Guan Xue was too busy to pay him any attention and warned him not to come to her office unless it was something important. When Song Zhuo Wen returned home, he discovered that his medicine bottle had been tampered with, and the fragrance on the bottle was all too familiar—it was the scent of the soap Xie Yue usually used.

He had prepared that bottle of medicine just in case, never expecting that Aunt Chang wouldn't expose him, but instead, Xie Yue, whom he had personally brought back, would reveal a flaw.
