Zheng Chaoyang deliberately made it difficult for Bai Ling, the KMT started cold chess. Zheng Chaoyang called Saner from the police station, but Saner knelt and begged for mercy as soon as he met, because he had taken Zheng Chaoyang with the Vanke Chief of the Security Bureau. Zheng Chaoyang did not investigate, but asked him about the whereabouts of Zong Xiangfang and his brother Zheng Chaoshan. Finally, he learned that his brother Zheng Chaoshan was arrested first, but later he called and released it. Zheng Chaoyang then took San’er to catch KMT agents.

After Rayong came to the police station, he took over some old police officers. Hao Pingchuan watched these lazy police officers very dissatisfied. The old police reported to Rayong that someone was robbing the grain store, and Rayong sent Zheng Chaoyang to deal with it.

When Zheng Chaoyang came out of the police station, he just met his brother Zheng Chaoshan. The two brothers were very excited to meet again, but Zheng Chaoyang had to leave because of a task. When Zheng Chaoyang Hao Pingchuan rushed to the grain store, he found that the people were about to grab grain, so he told the people that it was wrong to raise the price while taking the opportunity, and it was illegal to grab grain.

Hao Pingchuan expressed his dissatisfaction with these veteran police officers, and couldn’t see the profiteering behavior of private bosses. Luo Yong let him understand the importance of businessmen. Luo Yong sent Bai Ling as an assistant to Zheng Chaoyang. Zheng Chaoyang Haopingchuan was a little worried. Bai Ling forced Zheng Chaoyang to invite her to dinner. Zheng Chaoyang deliberately made it difficult for Bai Ling to make a pile of food that made Bai Ling appetiteless. In the end, Bai Ling was made into bean juice by Zheng Chaoyang because he couldn’t spit it out.

Luo Yong went to see Xu Zongren. Xu Zongren praised Zheng Chaoyang very much. Luo Yong thanked him for handing over the list of secret agents, destroying the secret service organization of the Kuomintang Secret Bureau. Luo Yong worried that Mao Renfeng would not give up, and reminded Xu Zongren to be more careful. Xu Zongren told Luo Yong that Mao Renfeng would start a “cold chess” that has been lurking in Peiping for many years.

Bai Ling was rectified by Zheng Chaoyang, so she stated that she had deciphered the code of the Police Corps, and Zheng Chaoyang finally had to apologize to her. At this time, a spy suddenly dropped a bomb in the casino of Xian Dengkui behind the three people. Zheng Chaoyang hurriedly pulled Bai Ling to protect him, so Bai Ling was not injured.

Zheng Zhaoshan is one of the KMT and one of the cold chess. Mao Renfeng sent him an order to reorganize a special operations team, and gave him the list of core members to let him get rid of Xu Zongren. Zheng Chaoyang found Xian Dengkui, and Xian Dengkui complained that he was involved after he was let go. Zheng Chaoyang reminded Xian Dengkui to send a sow dragon to assassinate himself. Zheng Chaoyang told Xian Dengkui that the explosion in the casino was caused by the black whirlwind and warned Xian Dengkui not to act rashly. Zheng Chaoshan went to assassinate Xu Zongren, but he encountered Vanke Chief.
