Luo Xiangqian found Ma Zutang to fight in the court, but Ma Zutang allowed him to build roads with peace of mind. Luo Xiangqian begged Ma Zutang to help him plead with his superiors.

Luo Xiangqian asked each of the soldiers to write a petition for battle, and as soon as the orders from their superiors arrived, they would launch across the board.Yu Huizhen wrote five long letters of petition, which she handed over to Luo Qianqian overnight.The brothers of the soldiers were gearing up and quickly wrote the petition for war and handed it in. Zhang Biao had finished writing it but had not yet handed it in. Luo Xiangqian ridiculed him and brought out Yu Huizhen to stimulate him. Zhang Biao handed the petition to Luo Xiangqian.

Luo Xiangqian led the soldiers to build the railway during the day and conducted large-scale military training with them at night, preparing to go to the front line at any time.Tian Jian and Ye Lan submitted a rerouting plan, which was quickly approved by the Ministry of Railways. Zhao Guoliang congratulated them and conveyed the instructions from his superiors. The military industrial troops building the railway were under the original organizational structure to fight in North Korea, leaving only cadres above the level of training.One hundred thousand migrant workers were recruited to build the railway.Ye Lan heard that Luo Qianqian was going to fight on the front line, and she immediately rushed to the company headquarters to see them off.

Ma Zutang convened a meeting of cadres above the level and announced the order to enter the DPRK. Luo Xiangqian immediately went back to report the good news to Zhang Biao and Wu Qiang.Ye Lan came to see Luo Xiangqian off and gave him his beloved pen as a thank you for his two life-saving graces. He hoped that Luo Xiangqian would write to her in time to report his safety. Luo Xiangqian was so kind but had no choice but to accept it. Wu QiangImplying that Luo Xiangqian wanted to repay the gift, Luo Xiangqian gave Ye Lan the military medal he won in the Huaihai Battle. Ye Lan was very moved, but she didn't expect Luo Xiangqian to give her such a precious gift.

Ye Lan came to see Sha Kai and brought his favorite preserves. Sha Kai was so happy that he could not open his mouth from ear to ear. When he learned that Ye Lan was seeing Luo Qianqian off, he felt sour in his heart.Ye Lan had already applied to his superiors to work in the Pioneer Company, and Sha Kai naturally wanted it. He took Ye Lan for a walk by the river. Sha Kai proposed to marry Ye Lan again. Ye Lan wanted to wait until the Chengdu-Chongqing Railway was repaired, but Sha Kai had to give up..

The party committee of the bureau decided to let Tian Jian succeed Sha Menghai as the director of the technical department. Only then did Tian Jian find out that Sha Kai had stolen Luo Xiangqian's research results. Sha Menghai did not report the knowledge. Thanks to Luo Xiangqian's intercession for them, they were spared punishment., Sha Menghai's old society was too bureaucratic, and the bureau leaders decided to remove him from his post. Tian Jian was worried that Sha Menghai would not be able to accept this fact for a while, so he suggested that he be made deputy director, and Zhao Guoliang wholeheartedly agreed.

Ye Lan was approved to work as a technician in the Pioneer Company, and he hurriedly came to bid farewell to Tian Jian.Tian Jian told Sha Menghai and Sha Kai that they had teamed up to steal Luo Xiangqian's research results, and Ye Lan was stunned.At night, Luo Xiangqian led the soldiers to conduct a large-scale military training. The soldiers trained hard and were not afraid of hardship or fatigue.

Ma Zutang called Luo Xiangqian to inform him that Zhang Biao and Wu Qiang went to the regiment headquarters. Luo Xiangqian mistakenly thought that the combat order had been issued, and he was extremely happy.Ye Lan sat in her room in a daze. Her mother saw that she was worried and urged her to marry Sha Kai as soon as possible. Ye Lan only wanted to repair the Chengdu-Chongqing Railway, so they went to the place where her father died to express condolences, and her mother no longer forced her.

Luo Xiangqian took Wu Qiang and Zhang Biao to the regiment headquarters early in the morning. Ma Zutang announced the order from his superiors. The Volunteer Army lacked political cadres. Wu Qiang followed the Volunteer Army into the DPRK. Luo Xiangqian and Zhang Biao stayed to continue building the railway. They were determined not to do it., Ma Zutang explained the whole story. Luo Xiangqian was very familiar with railway construction, Zhang Biao was from Sichuan, and could easily communicate with a large number of Sichuan migrant workers, and Ma Zutang was forced to stay. Luo Xiangqian and Zhang Biao had to leave in disappointment.

When Sha Kai learned of the regiment's decision, he made sarcastic remarks in front of Zhang Biao and called Luo Xiangqian a pig. Luo Xiangqian couldn't stand it and gave Sha Kai a severe lesson. Sha Kai was injured.Wu Qiang forced Luo Xiangqian to find Sha Kai to apologize, but Luo Xiangqian refused to go.Sha Kai went back to pack his luggage and wanted to go back to Chongqing to complain to Sha Menghai. Zhang Biao tried to persuade him, but Sha Kai refused.

Luo Xiangqiang could not go to the front line to fight, and he was punished for beating Sha Kai. He couldn't eat and couldn't sleep. Zhang Biao persuaded him to miss the meal time. Wu Qiang came to see the two of them, and Luo Xiangqiang felt resentful.
