Episode 15 recap: Shen Jin Zhen gathered evidence to prove Wei Ruo Lai's innocence.

Wei Ruo Lai was imprisoned and the prison boss ordered the inmates to teach him a lesson, resulting in Wei Ruo Lai being beaten up. Shen Jin Zhen tirelessly searched for evidence to exonerate Wei Ruo Lai. Lin Qiao Song instructed Wei Ruo Lai to fire another shot to confirm that he was the murderer of Li Cheng Da. Shen Jin Zhen presented crucial evidence.

Wei Ruo Lai's involvement in the Communist Party case caused a great sensation in society, fueling ongoing public outcry and posing a significant challenge to the central bank and the Nanjing government. The Nanjing government dispatched Ming Da, the director of Chiang Kai-shek's office, to Shanghai to handle the case. Ming Da convened a special investigation team comprising Deng Ze from the central bank's disciplinary department, Kang Shao Jie, Lin Qiao Song, and a third-party firearms expert named William. Shen Jin Zhen served as William's translator during the case analysis meeting, where Deng Ze emphasized the central bank's involvement in every investigation.

Lin Qiao Song strongly protested, knowing that Deng Ze had a close relationship with Shen Tu Nan and fearing that Deng Ze would protect him. Deng Ze immediately stated his regret for handling the case impartially and retorted at Lin Qiao Song.

Upon hearing that Shen Jin Zhen and Deng Ze recommended William to the special investigation team, Kang Shao Jie instructed Lin Qiao Song to quickly find William's weakness and use any means necessary to bribe him to confirm Shen Tu Nan's involvement in the Communist Party. Lin Qiao Song retrieved a bullet from Li Cheng Da's body and handed it to Lin Qiao Song as evidence. Lin Qiao Song used Wei Ruo Lai to rob Zhang Ming Quan and used his gun to kill a death row inmate. He extracted a bullet from the inmate's body, falsely implicating Wei Ruo Lai as the shooter who killed Li Cheng Da.

Lin Qiao Song tortured Wei Ruo Lai severely, leaving him covered in injuries, before throwing him into the prison. Prison boss Jiang Hu Hao forced Wei Ruo Lai to massage his feet, and Wei Ruo Lai had no choice but to comply. Jiang Hu Hao heard that Wei Ruo Lai used to work at the central bank, which angered him. He ordered the inmates to beat Wei Ruo Lai, causing him to lose consciousness.

Li Cheng Da remained in a coma due to intracranial bleeding. Lin Qiao Song pressured the doctor to perform a craniotomy on him, but the doctor hesitated due to uncertainty. Lin Qiao Song harshly reprimanded the doctor. Wei Ruo Lai regained consciousness in a dazed state, feeling extremely hungry. He struggled to get up and wanted to drink water, but Jiang Hu Hao forbade him from drinking and forced him to drink urine. Wei Ruo Lai was tortured to the point of suffering greatly, and the inmates felt pity for him.

Jiang Hu Hao suppressed his anger and shared the tragic experiences of each inmate in the same cell who had lost everything due to stock market speculation. Wei Ruo Lai learned that they had been arrested a few days ago for protesting outside the municipal government, and he sympathized with them deeply. The special investigation team interrogated Wei Ruo Lai, and Shen Jin Zhen felt deeply saddened upon seeing Wei Ruo Lai's numerous injuries.

Lin Qiao Song questioned Wei Ruo Lai persistently, and Wei Ruo Lai admitted to robbing Zhang Ming Quan's handgun. He stated that the incident had nothing to do with Shen Tu Nan, and he did not kill Li Cheng Da. He even claimed that he didn't know how to use a gun. Lin Qiao Song became infuriated and continued to pressure Wei Ruo Lai. William suggested that Wei Ruo Lai be taken to a shooting range to test his skills. Deng Ze also agreed with William's decision, so Lin Qiao Song had no choice but to send someone to take Wei Ruo Lai to the shooting range.

Wei Ruo Lai fired six shots in a row, with four hitting the target. William noticed that Wei Ruo Lai's grip on the gun was incorrect, which made Lin Qiao Song suspicious that Wei Ruo Lai was pretending not to know how to use a gun. William conducted a data analysis based on technical aspects and concluded that the wound on Li Cheng Da's chest was very professional and not caused by Wei Ruo Lai. Lin Qiao Song refused to accept this and challenged William to inspect the crime scene. Reluctantly, Lin Qiao Song agreed to the suggestion.

The prison guard delivered newspapers to the inmates every day on schedule. Jiang Hu Hao and the other inmates in the same cell had bought Hengmei stocks, hoping to turn their luck around. Wei Ruo Lai advised them to sell as soon as possible, warning that they would suffer heavy losses otherwise. Jiang Hu Hao didn't believe him, so Wei Ruo Lai analyzed the trend of the stock in a simple and understandable manner. Impressed by his explanation, Jiang Hu Hao made a deal with Wei Ruo Lai, asking him to recommend three stocks within five days. If successful, Jiang Hu Hao would consider him a friend; otherwise, he would not show any mercy.

William conducted an investigation at the crime scene and found footprints that did not match Wei Ruo Lai's. He requested a reinvestigation of the case, but Lin Qiao Song obstructed his efforts out of fear of being exposed. Deng Ze threatened to involve Ming Da, which made Lin Qiao Song back down. Lin Qiao Song presented the bullet he had obtained from Li Cheng Da's body to the special investigation team. Shen Jin Zhen carefully examined the scene and discovered a bullet casing in the grass, which she immediately showed to Deng Ze and William.

Wei Ruo Lai recommended three inactive stocks, promising that they would break even within five days and double in value within two months. Jiang Hu Hao and the others were skeptical but still bought those stocks. From that day on, the three recommended stocks continuously declined for four days, causing panic among Jiang Hu Hao and the others. Wei Ruo Lai realized that the market manipulators were washing out the stocks and advised them to wait and see.

As Wei Ruo Lai had predicted, the three stocks started to rise on the fifth day. Jiang Hu Hao and the others were in awe of Wei Ruo Lai and treated him with great respect. They even gave him the best spot and followed his instructions. Lin Qiao Song handed the bullet extracted from the death row inmate to the special investigation team, while Shen Jin Zhen compared it to the bullet casing she had found at the scene. They were not the same model, and the bloodstains on the bullet provided by Lin Qiao Song were fresh, which did not match the time of Li Cheng Da's shooting. Shen Jin Zhen insisted on involving a forensic expert and conducting a blood type cross-matching between the bloodstains and Li Cheng Da. Lin Qiao Song was dumbfounded and quickly went to replace the bullet with the one taken from Li Cheng Da's body.

William discovered that the bullet found in Li Cheng Da's body did not match the model of Wei Ruo Lai's gun. The bullet and the bullet casing found by Shen Jin Zhen were of the same model, eliminating Wei Ruo Lai's suspicion of shooting Li Cheng Da. Lin Qiao Song had fabricated evidence and intended to bring down both Wei Ruo Lai and Shen Tu Nan, but his plan backfired. Worried that Shen Tu Nan would seek revenge, Lin Qiao Song desperately tried to win Shen Jin Zhen over and proposed a deal, using Wei Ruo Lai's life as leverage. However, Shen Jin Zhen scoffed at Lin Qiao Song's proposition.

Lin Qiao Song knew that this case had attracted the attention of high-ranking officials in the Nanjing government, so he dared not act recklessly. The three stocks recommended by Wei Ruo Lai continued to rise, and Jiang Hu Hao and the inmates idolized him. Wei Ruo Lai advised them not to invest in stocks after their release, as the stock market was a game for capitalists, and ordinary people could not afford to play it.
