Episode 17 recap: Shangguan Qin successfully solved the case.

After returning, Li Bing began to analyze the condition of the second son of the Qin family. He started to feel that it was impossible for the person to quit drug addiction in such a short period of time. After hearing what people around him said, he continued to speculate on other possibilities. However, he was suddenly interrupted by A Li Ba Ba who came in from outside. At this moment, A Li Ba Ba told everyone about the incident of Shaoqing being lost in a dejected manner. Upon hearing this bad news, the people around were astonished. Wang Qi blamed A Li Ba Ba angrily upon learning about the loss. Unexpectedly, when they criticized A Li Ba Ba, Shaoqing himself returned and stood in front of everyone.

This time, not only did Shaoqing return, but he also brought a woman with him. When everyone saw this delicate and charming woman, they became curious. After sitting down, the woman next to them directly revealed that she had gone to redeem the qin (a musical instrument). When the people around heard that the second son of the Qin family himself could concoct a medicinal powder called "Fifty Scattered Fragrances," they became even more curious. Afterwards, they planned to continue investigating the whereabouts of their accomplices.

Later, everyone continued to chase after Zhao Daxian's figure in the cave and saw him hiding in the cave and eating poisonous powder. They were preparing to capture him when suddenly the person sitting in front of them mumbled and directly consumed the pill, which made him immensely powerful. However, he was still greedy and wanted to consume all the medicine. Eventually, his body couldn't bear it anymore, and he collapsed on the ground, foaming at the mouth. The people from the Dali Temple around directly carried him away. Seeing the qin on top, Li Bing and the others thought the case had been successfully concluded.

However, Shangguan Qin, prompted by the people around him, returned and saw the true face of Kou Niang. At this moment, she did not intend to kill him but only wanted to retaliate against those who had harmed her beloved. After they came out, they met Li Bing, who knew the truth of the matter. Then, everyone sat down together and clarified the whole situation. They revealed that the mastermind behind all this was the father of the second son of the Qin family. Upon hearing this appalling story, the people around could hardly believe that such a refined teacher could do such things. Later, they also received the news of the death of the second son of the Qin family's father, knowing that he had been poisoned to death.

After the entire case was solved, Wang Qi looked at his friend beside him, who still seemed like a bookish person, and continued to remind him not to end up like the Qin family by taking poison in the end. The person in front of him didn't show any intention to respond and simply continued to look at the book in his hands. After that, several members of Mingjing Hall gathered together again, preparing to cleanse the house and dispel any lingering evil spirits as Qingming Festival approached. Chen Shi, standing nearby, still didn't believe the reasons behind their actions. Sun Bao, who was standing next to him, directly pulled him into the house, preparing to continue explaining.

Unexpectedly, while A Li Ba Ba and Cui Bei were walking on the street after that, they encountered more trouble. Taking advantage of A Li Ba Ba's absence, everyone began discussing the misfortunes that occurred during Qingming Festival. What made it even more terrifying was that within the crowd, nobody knew who it was all about. Just as the story reached an exciting part, Li Bing suddenly pushed open the door, scaring everyone half to death. After he left, they hurriedly lit the candles and, with the people around, Li Bing once again reminded them to devote more time to studying and not to listen to nonsense. Unexpectedly, the next day, Li Bing caught a cold due to an encounter with Cui Bei, and everyone started discussing Cui Bei's situation.
