Su Wuming insisted on speculating again. He believed that after Chu Bin was rescued by his grandmother ten years ago, he was heartbroken due to emotional trauma. He did not return to his hometown because he felt that he was too embarrassed to face his relatives. In particular, his sister Chu Jia had strongly opposed his affair with Li Yun. However, Cherry expressed confusion about this speculation and believed that its logic was open to question.
Su Wuming further elaborated, mentioning that Fang Juan's chance encounter with Chu Bin unexpectedly inspired Chu Bin's desire for revenge. Not to be outdone, Fang Juan funded her grandma to open a hotel and invited Mudan to join in to help. At the same time, Chang Le was honest and confessed the truth to Shen Ping. Shen Ping was frightened and turned to his childhood sweetheart Fang Juan for help. Fang Juan cleverly arranged a meeting between Li Yun and Chu Bin, and the two women gained insight into Li Yun's character.
Originally, Fang Juan intended to use Chu Bin's help to get rid of Li Yun, but he did not expect that Li Men met Chu Bin first, and Li Men decided to join them with his integrity and sense of justice. The arrival of Li Men not only provided an alibi for Chang Le and others, but also allowed everyone to testify against each other and form a solid line of defense. Fang Juan is even more resourceful and uses meager change to win people's hearts to ensure that his plan is foolproof.
After in-depth investigation, Lu Lingfeng finally confirmed all the abnormalities he had noticed before. Su Wuming then revealed that Da De was terrified because of his insight into a certain plan, and rushed to make a piece of clothing overnight to deal with it. Li Men tried his best to dissuade Li Yun from hurting innocent women again, but Li Yun was stubborn and insisted on going his own way, and eventually a conflict broke out between them. Ignoring the dissuasion, Li Yun broke into the room and found that there was no one there except a bathtub. Due to head discomfort, he lay down on the bed and fell asleep.
Lu Lingfeng questioned Li Men's whereabouts, believing that although he climbed out of the roof, he happened to catch up with the incident and lacked conclusive proof of alibi. Su Wuming further analyzed that water alone was not fatal. The murderer cleverly mixed lime into the water, causing Li Yun to suffocate. Shen Ping used that special piece of clothing to squeeze Li Yun, eventually killing him. Lu Lingfeng speculated that the reason why the murderer took such extreme measures was because Li Yun had committed many crimes, not only hurting several women, but also arousing public outrage. He asserted that there was no murderer in the traditional sense in this case, but a desperate self-defense fight by the victims.
When the Huangpu Forum heard this, they couldn't help but burst into laughter, recalling the scene where the black head surrendered to the police a few days ago. Lu Lingfeng woke up and found Su Wuming kneeling on the ground, expressing his deep apology to his mentor. Su Wuming believes that these actions are not out of malice, but rather the victims learn to fight back in order to protect themselves after being hurt. Lu Lingfeng felt deeply guilty and worried about how he would face his mentor after the apprenticeship agreement was made six months later.
Blackhead admitted that he was the murderer of Li Yun. At that time, he was holding lime and witnessed Li Yun losing his life in front of him. On the other side, Chu Bin was burning paper money for Li Yun, grateful for her sister's persistence, and reflecting that if he could listen to her sister's advice, maybe everything would be different. The two sisters decided to join hands again and explore the world together. Pei Xijun was also pleased with the fate of the two women. Fang Juan and Li Men each embarked on a new journey, and Peony also ushered in a better life.
Lu Lingfeng and Su Wuming saw everyone getting on the right track, and their hearts were filled with joy, thinking that the successful conclusion of the case was perfect. Shen Ping worshiped Lao Fei as his master, and both master and disciple were very happy. Xue Huan seeks out Lu Lingfeng, but Suolong's provocation fails and is defeated. Lu Lingfeng received an order to return to Beijing to deliver golden peaches, and Su Wuming was wary of the hidden secrets. Lu Lingfeng felt that it was difficult to develop his talent and ambition, and Su Wuming vowed to share the difficulties. Su Wuming persuaded Lu Lingfeng and Pei Xijun to visit Dunhuang Mogao Grottoes, and Lu Lingfeng decided to go west to explore the secrets. The six of them went to Dunhuang together, reciting poems and painting, and enjoyed a rare time together.
