Based on information provided by detective Luo Jun from the criminal police team, the Xihai City criminal police set a comprehensive trap for the upcoming fake currency transaction of the Qian Haiyang crime group. At the transaction site, the appearance of a stranger puzzled police captain Su Changfeng, and raised suspicions in Qian Haiyang, leading him to cancel the deal. Faced with this sudden change, Su Changfeng decisively ordered an inspection of a suspicious fishing boat at sea and searched Qian Haiyang's temporary command center, but all efforts proved futile. The keenly perceptive Qian Haiyang conducted an internal investigation and clean-up, preferring to err on the side of caution rather than let anyone slip through. Our undercover agent, Luo Jun, sacrificed his life. Su Changfeng, reflecting on this painful loss, resolved to pursue the case to its conclusion. The stranger who disrupted the transaction scene, limping with a gas canister slung over his shoulder and a lighter in hand, threatened to blow up the nightclub—his name was Qi Bing, a detective who had not yet officially joined the criminal police. This “disruption” occurred when he had just arrived in Xihai City and casually encountered some gangsters selling counterfeit money. He intended to bring a “gift” to the police station, but ended up mistakenly barging into the transaction site and got injured by my armed police. After the incident, Qi Bing deeply reflected on the events, taking the opportunity to fulfill Luo Jun's unfinished mission. His profound remorse and the professional sense of duty as a policeman led him, under the careful arrangement of the chief and Su Changfeng, to begin his undercover operation—Qi Bing assumed the alias Liu Dabin and rushed into the cleansing banquet prepared for the recently released Luo Zigjun, demanding an explanation. His reckless behavior immediately caught Qian Haiyang's attention and earned his admiration, prompting Qian Haiyang to keep him despite opposition. Qi Bing successfully infiltrated the criminal group, which also earned Su Changfeng's admiration for witnessing it firsthand. However, Su Changfeng still harbored unspoken unease regarding Qi Bing’s disruptive actions that led to Luo Jun’s sacrifice, as well as the fact that Qi Bing once dated Yinghong, who is now Su Changfeng's girlfriend. On the surface, Qian Haiyang allowed Qi Bing to stay close but remained wary of him, keeping him out of his “business.” Qian Haiyang and his wife, Bao Nana, were at odds; they fought whenever they met, a situation rooted in events before their marriage. Bao Nana was the girlfriend of Su Changfeng's long-lost brother, Su Changling, whom Su Changfeng had been searching for. Bao Nana could never understand how she could have shot Su Changling, while Qian Haiyang possessed recorded footage of her doing so. This haunted her daily, leaving her often waking in terror from nightmares, blaming Qian Haiyang for everything. As a result, she undertook many unbelievable actions; she used her beauty and wealth to manipulate others into killing Qian Haiyang. Specifically, she risked everything to secretly recruit Qian Haiyang's capable assistant Luo Zigjun to assassinate him. When her plot was revealed, the cunning Qian Haiyang had alternative motives and forgave Luo Zigjun. Similarly, after being rejected by Qi Bing, Bao Nana immediately suspected him of being an undercover agent because she had previously used the same method against Luo Jun. Chen Yanli, driven by life's hardships, became the shadow replacing Bao Nana, bringing substantial trouble for Qi Bing because she was a former middle school classmate of his. Qi Bing maintained his composure, transforming Chen Yanli’s certainty about his identity into doubt. However, Chen Yanli never mentioned it before Qian Haiyang because she harbored feelings for him. Moreover, Chen Yanli was quite unwilling, still hoping to win over the devil Qian Haiyang. However, when disillusioned, she became romantically involved elsewhere for the sake of money and going abroad, ultimately paying with her life for her transgressions. As Qian Haiyang's business grew from small to large, he became dissatisfied with merely dealing in renminbi, wanting to go straight to producing counterfeit currency. He joined forces with the overseas counterfeiting kingpin Amin, but greed led them to openly contend for profit while plotting against each other, eventually resulting in Amin's death at Qian Haiyang's hands. While disposing of the remaining counterfeit renminbi in the warehouse, Qian Haiyang connected with a female police officer, Yinghong, who was posing as an informant. Yinghong fought her way through, ultimately making a deal with Qian Haiyang, but at that moment, Qian Haiyang discovered Yinghong's true identity, placing him in imminent danger. Unexpectedly for Qi Bing, Qian Haiyang demanded that he personally shoot Yinghong… A series of misunderstandings led to Qi Bing losing contact with the criminal police, and his unusual actions aroused suspicion and discomfort from Su Changfeng and the chief. Meanwhile, Qi Bing endured internal conflicts, continuing to seek advantageous evidence by Qian Haiyang's side. Qian Haiyang sought help from Liu Yun, who was the head of the bank credit department and a classmate of Bao Nana, to arrange illegal loans for his counterfeiting plans. Liu Yun repeatedly delayed approving the loan, citing incomplete documentation. Seeing that coercion and seduction were ineffective, the ruthless Qian Haiyang killed Liu Yun's daughter’s kidnapper, Pi Zai, in front of Liu Yun to win his loyalty. However, when Liu Yun learned in the interrogation room that Pi Zai's death was a ruse orchestrated by Qian Haiyang, his defense collapsed… While secretly involved with Chen Yanli, Amin's subordinate, Kang Bo aimed to use her to steal the counterfeit bill templates from Qian Haiyang, but his plans went awry as Chen Yanli would never have the opportunity to come into contact with such items. After their affair was revealed, Qian Haiyang tested Qi Bing again, ordering him to kill Chen Yanli and Kang Bo. However, the clever plans backfired, and Qian Haiyang found himself ensnared in a trap set by our criminal police. After learning of Kang Bo and Amin's deaths, Qin Wenbin, a strategist who had long been beside Qian Haiyang and was secretly rebellious, prepared to assassinate Qian Haiyang and take his place. Qian Haiyang, having already foresaw the betrayal, would not let him off easily. Qin Wenbin believed he had evidence of Qian Haiyang's life and death and personally met him to negotiate, but as the saying goes, the higher the reach, the greater the fall—Qin Wenbin ended up on his knees before Qian Haiyang, weeping and begging for mercy until lying at Qian Haiyang's feet. Qi Bing underwent several tests by Qian Haiyang. Just as Qian Haiyang prepared to reuse Qi Bing, Qian Haiyang discovered the communicator that Qi Bing used to contact Su Changfeng, enraging him. Qian Haiyang lured Qi Bing and Su Changfeng into a shipping container at the dock, intending to kill them both… After a fierce confrontation with Qian Haiyang, Qi Bing ultimately managed to uncover all of Qian Haiyang's criminal activities and obtained irrefutable evidence! Qian Haiyang did not expect to fall into Qi Bing's hands.
