1. In the autumn of 1941, a large number of Japanese warplanes bombed Chengdu violently. Yang Shaocheng, the shopkeeper of Jinjiang Spring, a century-old brand, witnessed the big explosion of the jeep of Ye Huaizhong, the commander of the garrison. Commander Ye was killed on the spot, and the adjutant Ling Hui was covered in blood and was seriously injured. Shao Cheng sent him to the hospital. Chen Jianfeng, deputy stationmaster of Juntong Station, rushed to the scene where the future father-in-law Commander Ye was bombed. He was surprised to find that a German-made time bomb was hidden under the jeep. He immediately realized that this was a murder.

2. In the hospital, Lieutenant Ling saw the captain of the operation, Xu Ergen, breaking in with people and secretly put an American cigarette case in Shao Cheng's pocket. Xu Ergen brought Shao Cheng and Ling Hui back to Juntong Station for interrogation. Ye Mei, the daughter of Commander Ye, worked as a confidential officer in Juntong Station. She learned that Shao Cheng saved Linghui, an agent of the * * * Party lurking in the headquarters, and broke into the interrogation room with a gun, so she wanted to shoot Shao Cheng, but was persuaded by Chen Jianfeng.

3. Adjutant Ling was killed on the scaffold, which greatly shocked Shao Cheng. Chen Jianfeng released his friend Shao Cheng privately, and had a fierce conflict with the stationmaster Gu Huaze. Back home, Shao Cheng found a pawn ticket hidden in the inner interlayer of the cigarette case. Mao Renfeng sent a telegram instructing Chen Jianfeng to investigate the death of the commander. Chen Jianfeng wanted to bring down Gu Huaze, but Gu Huaze felt that Chen Jianfeng's background was complicated, and sooner or later he took his place and wanted to get rid of him.

4. My younger brother Shao Yi was addicted to gambling, and lost the title deed of the house to Ma San, the leader of Paoge, the hand of Chen Jianfeng's father Chen Ziqiu. Shao Cheng promised to pay back the money and wanted to redeem a treasure with the pawn ticket given by Lieutenant Ling, but what he got back was a copy of Shan Hai Jing in the late Qing Dynasty. The Japanese puppet spy Gu Youfeng followed Shao Cheng to the pawnshop, but Shao Cheng escaped from the back channel, was stunned by Ye Mei and hung on the roof beam. At this point, Chen Jianfeng tracked the Japanese and Puppet agents here, but Shao Cheng took advantage of Ye Mei and Chen Jianfeng's misunderstanding and stole Shan Hai Jing. When I got home and opened the book, I was surprised to find that Shan Hai Jing turned out to be an invisible map. Shao Cheng went into the underground cave alone, and there was an underground network extending in all directions. There were a lot of arms and opium in the tunnel. He suddenly understood that as long as the arms were lit, the city would be doomed!
