Commander Yao Zhe led an elite army to Suijing City quickly. After joining forces with Yan Yifu, the battle started at four in the morning. He was ambushed when he entered the Japanese trench warehouse. Being outnumbered, Yao Zhe decided to implement the second plan and lead the troops to evacuate. Yao Zhe and others were seriously injured on their way back. At this time, Dr. Miao, who faked his own death, took credit for the Japanese army's Katayama Shaozuo, ordered the whole city to be under martial law, and seized Yao Zhe and others. Under the cover of Yan Yifu and others, Yao Zhe came to nurse Chen Juan's house to take out the bullet. The Japanese army is approaching. Before Japanese leader Katayama Shaozuo arrived at Chen Juan's home, Yao Zhe, Yan Yifu and others had successfully retreated, and a platoon leader and other soldiers sacrificed to cover Yao Zhe's courage.

Yao Zhe and others hid in Zhao Long Temple, and then the Japanese army came to Zhao Long Temple to search and found nothing. The abbot of the temple, Batu, decided to take Yao Zhe, Xiao Taiyuan, Yan Yifu and Chen Juan out of the city disguised as lamas. Shaozuo Katayama led the Japanese army to guard the city gate and investigate suspicious pedestrians. In order to cover Yao Zhe, Yan Yifu and other soldiers deliberately exposed their identities. In the gunfight, Yan Yifu was captured by the Japanese army, and Yao Zhe, Xiao Taiyuan and Chen Juan left the city of appeasement smoothly. Pianshan Shaozuo tortured Yan Yifu and told him the whereabouts of Yao Zhe and others. His indomitable behavior angered Pianshan Shaozuo, and he was subjected to Ma Fengshan's more cruel criminal law.

Yao Zhe met Zhang, the detachment leader, at Zhang Ziya's temporary camp. They studied the reasons for the failure. Chen Juan became the object of suspicion for the time being. She was worried and insisted on going back to appeasement city. Yao Zhe was worried about the danger of leaving the team and asked her to obey the organizational arrangement. Chen Juan is going to run away when he goes to the toilet. Zhang questioned the authenticity of revolutionary identity, while defending his innocence. In the middle of the night, Yan Yifu of the gendarmerie prison was suddenly rescued by Dr. Miao, and then they joined Yao Zhe. At the same time, Chen Juan got the approval of his boss, and everyone got together for a drink. Yan Yifu had a tryst with Chen Juan. Faced with national enemies and hatred, Yan Yifu could not promise the future of Chen Juan. Chen Juan loves Yanyifu deeply, and she is very sad. The conversation between them alarmed Yao Zhe and Xiao Taiyuan. In the evening, Dr. Miao went to a quiet place, secretly put the letter on the land god and sat down. He thought he was unknown, but he was targeted by a soldier. The soldier went back to report to Yao Zhe, who ordered close surveillance.

Yao Zhe knew that the enemy was coming soon. He and battalion commander Zhang arranged for the transfer of troops, and specially arranged for Dr. Miao to return to Suijing City to get some medicine and then meet with Deputy Commander Chen in Yinggou. At the same time, he received an intelligence order from Pianshan Shaozuo, and the troops that followed came at Zhang Ziya, but closed their eyes. Pianshan was furious with Shaozuo and ordered a small team to investigate. They met in the narrow valley, and Yao Zhe quickly attacked and annihilated the enemy in one fell swoop. Yao Zhe began to detour to catch up with the enemy. He was going to send a telegram to Deputy Commander Chen, but he knew that the telegraph operator was dead. Chen Juan volunteered when she was anxious. Yao Zhe dictated and ordered Deputy Commander Chen to lead the forces of Daqingshan to launch an all-round anti-encirclement campaign against the Japanese army in Yingying ditch.

Dr Miao, who returned to appeasement city, reported the situation to Shaozuo Pianshan, but was questioned by Shaozuo Pianshan and died under the bayonet. Just then, he received Yao Zhe's troops, but he wanted to assemble a telegram from the eagle trench. He ordered the troops to March quickly to Yinggou. At the same time, Yao Zhe's investigators have reported to Yao Zhe the situation of Japanese troops in the city of appeasement. Yao Zhe and his army made a detour to the city of appeasement. Yan Yifu was puzzled and mystified. In Lijiatuo, a suburb of appeasement, Chen Juan suddenly sent a message, and Yan Yifu questioned her identity. Chen Juan suddenly pulled out his gun and aimed it at Yan Yifu. When Yao Zhe and others arrived, they revealed that Chen Juan was a spy sent by the Japanese army. In fact, all this is under Yao Zhe's control. Yao Zhe used Chen Juan and Dr. Miao to pass false information to the enemy, and came up with a plan to transfer tigers in the mountains and build a long road.

In the middle of the night, Yao Zhe led his troops to attack the trench warehouse and wiped out the Japanese puppet troops guarding the warehouse. Blow up the trench warehouse. The troops led by Deputy Commanders Yao Zhe and Chen lurked on the hillside and wiped out a few troops in Huiyuan Pianshan in one fell swoop.
