Mao Renfeng is cruel, cunning and suspicious. One day in the autumn of 1948, Mao Renfeng was intimate with a romantic woman, and she happened to be caught in the eye. From then on, Mao Renfeng always thought that Shen Zui could not get along with him, so he set up defenses everywhere. When Mao Renfeng fled the mainland with Chiang Kai-shek in May 1949, he deliberately placed Shen Zui next to Yunnan Provincial Chairman Lu Han in the name of the security commissioner of the Yunnan Region (actually the head of the Yunnan Station of the "Military Reunion") to monitor Lu Han's actions. At this time, the national liberation wave was surging, and huge slogans "anti-dictatorship, anti-civil war, and anti-hunger" appeared everywhere in Yunnan, a borderland. Lu Han, who had already seen through the current situation, gradually moved closer to the Chinese Communist Party and people, which made Chiang Kai-shek deeply uneasy. In early August of the same year, Mao Renfeng commanded remotely from Taiwan, asking Shen to quickly eliminate five important figures including Yang Jie, Chen Fuguang, and Xie Chongwen who were closely related to Lu Han, the former president of the Central Army University, and had participated in Lu Han's anti-Chiang struggle. Shen Zui was shocked when he heard the news, thinking that Mao Renfeng is really poisonous, isn't this blocking my way out? He clearly knows that Lu Han is moving closer to the Communist Party. If I kill Lu's cronies, once Yunnan is liberated, won't my family die without a burial place? So Shen took a soft-footed approach to Mao's order, stalling for time, hoping to get away with it. Seeing Shen Zui's delay, Mao Renfeng made a trick, moved Chiang Kai-shek, and issued a death order to Shen Zui in the name of "Chairman", restricting Shen to "kill Yang Jie within 3 days." Now Shen Zui panicked, thinking about killing only one person, he didn't dare to resist anymore, and decided to assassinate Yang Jie. Unexpectedly, Shen's mother found out about this and immediately dissuaded Shen Zui and informed Yang Jie so that Yang could escape. Unexpectedly, just when Yang Jie fled Kunming, Lu Han, under the dual pressure of Chiang Kai-shek and Acting President Li Zongren, ordered a city-wide manhunt. Mao Renfeng saw the opportunity and sent Xu Yuanju, the director of the Southwest District of the Secrecy Bureau, to cooperate with Operation Shenzui. As soon as Xu Yuanju and Shen Zui met, he condescendingly took out a blacklist from his pocket, pointed at the first name "Yang Jie" and scolded Shen: "This is the name personally called by the chairman of the committee, but you still refuse to kill him, Mao The director is very dissatisfied with you and wants you to give up your merits." On the surface, Shen Zui admitted his incompetence and expressed his sincerity, but secretly helped Yang Jie escape. That night, Shenzui pretended to be confident and led people into Yang Jie's house. Naturally, the building was empty. Seeing that he could not catch Yang Jie, Xu Yuanju arrested other "political prisoners". More than 400 people were arrested in one night, many of whom were students from colleges and universities. Shen Zui knew that most of the people inside were innocent, but he succumbed to Mao Renfeng's orders and did not dare to disobey. The agents originally hoped that this would please Mao Renfeng, but they didn't know that the focus of Mao Renfeng's killing was Yang Jie. When they heard that Yang Jie had slipped through the net, they took a special plane from Taiwan to Kunming in anger. As soon as he got off the plane, he glared at Shen Zui who came to greet him, and said angrily: "Old Shen, you have disappointed me with this action. The commissioner has a lot of objections to you." Mao told Shen Zui that he had two purposes this time. : The first is to force Lu Han to kill the captured prisoners and make Lu Han's hands covered with blood to block his future escape route to the Communist Party; the second is to further clarify that he must defend Yunnan to the death and there will be no telegram from "Generalissimo Chiang Kai-shek" The order cannot take a step away, otherwise he will be killed without mercy. Shen Zui nodded on the surface, but was extremely dissatisfied inside. The Jiang family dynasty has reached a critical moment. Can I, Shen Zui, turn things around? Shen hates Mao Renfeng to death - it's all the fault of you, the evil wolf, we are enemies on a narrow road, this time I have to make you die for no reason! As a result, Shen hid a murderous intention against Mao Renfeng and decided to use poison to kill Mao and prevent Mao from dying on the mainland. Shen Zui searched for poison secretly and found that there were two kinds. One is a local medicine prepared by ethnic minorities in Yunnan, called "Gu", also known as "hundred-worm powder". It is a brown fine powder that cannot be identified if it is put into vegetables and coffee. It will only occur half a month after taking the medicine. When it occurs, the whole body will convulse and die in extreme pain. The first type is imported medicine powder. This medicine has no smell. Just put a spoon in the food and put it three times, which will cause heart necrosis. Shen Zui felt that the second method was not very reliable and decided to use the first method. Mao Renfeng first lived in a spy's home, and Shen Zui sent his personal adjutant Yan Qisheng to serve as a guard for Mao. Shen Zui calculated the date and felt it was too early, so he didn’t start yet.

Mao Renfeng stayed there for more than 20 days, but made no progress in his work. Every time he asked Lu Han to sign the list of executing more than 400 prisoners, Lu Han always refused to sign on the excuse of insufficient evidence of guilt. Mao Renfeng gave in to a quarter of the number of people, but Lu Han's attitude remained the same. Mao Renfeng pressed hard, and Lu Han said with a straight face: "If you force me like this, can I still be the provincial chairman?" Mao Renfeng hit the wall several times and became extremely angry. He returned to Shenzui's home and walked in. Just accuse and lose his temper, saying that Shen is disloyal to the party and the state. Shen Zui was already angry, but this strengthened his determination to poison Mao Renfeng. Coincidentally, at this time, there was a sudden power outage in Kunming. Mao Renfeng was afraid of being plotted and became suspicious. He took the opportunity to go crazy and cursed Adjutant Yan for "not succeeding enough and failing too much." Yan Qisheng refused to accept the humiliation and complained to Shen Zui. Shen Zui felt angry and was reminded to mix the poisonous powder into Mao Renfeng's meals the next day. That night, the power plant turned on power again. Shen Zui came to Mao Renfeng's room. Mao patted Shen on the shoulder and said emotionally: "Old Shen, you have been consistent with me over the years. It is rare that you are sincere. I Being angry with you is an obstacle in my heart, it's my fault, don't take it personally." Her eyes seemed a little moist as she spoke, and Shen Zui, who had always valued loyalty, gave up the thought of killing again. Mao Renfeng couldn't bear the loneliness. In this troubled year, she ignored the crisis of the "Party and State" and brought a Peking Opera actress to her house to fool around all day long. Shen Zui despised this. Shen went to report to Mao Renfeng and accidentally found a telegram from Taiwan urging Mao to return to Taiwan. Shen Zui was shocked and thought that if he didn't take action, he would miss this golden opportunity. So he planned to poison Mao Renfeng while he was having dinner that day. However, when Shen Zui left the room, Mao Renfeng said: "Old Shen, I admire your loyalty from the bottom of my heart. If Boss Dai is alive in heaven, he will smile." A "Boss Dai" reminded Shen Zui again. , he asked himself in his heart: If I kill Mao Renfeng, wouldn’t I feel sorry for Boss Dai? He relented again. At this time, news came that the Jiang family and his son were coming to Kunming in person. After thinking about it for a few days, Shen Zui threw away a few packets of poisonous powder. A few days later, Mao Renfeng left Kunming. Before leaving, he instructed Shen Zui: "You must stick to Yunnan. You must either pull up a team and go into the mountains to fight guerrillas, or imitate Wang Zuo's fake surrender with a broken arm in order to make a comeback." As soon as Mao Renfeng left, Shen Zui suddenly understood and said to his family: "I You shouldn't throw away the poisonous powder." Shortly after Mao Renfeng left, on December 9, Shen Zui participated in the Lu Han Uprising. Afterwards, Shen said to Lu Han: "I regret not killing Mao Renfeng with my own hands." Lu Han replied: "It is not too late to let the people kill him again!"
