Episode 12 recap: Luo Xiang Qian destroyed the nest of the Mountain Trolls and the Vanguard Company exceeded the target in collecting sleepers.

Luo Xiang Qian visited Professor Tian in the hospital and comforted him not to rush to leave, but to take good care of his health. Ye Lan also came in and advised Professor Tian not to be eager to leave the hospital. After bidding farewell to Professor Tian, Luo Xiang Qian left, and Ye Lan accompanied him. Ye Lan mentioned the matter of Sha Kai at the construction site and said that Sha Kai invented the method of layered backfilling and compaction. Luo Xiang Qian didn't say much, only commented that Sha Kai is doing well in his training and hoped that Ye Lan would go to the construction site to support road construction.

Ye Lan said that she has already applied to Director Zhao and is ready to go to the construction site for training. Luo Xiang Qian immediately expressed a warm welcome. The exploration team encountered danger, which prompted the higher-ups to take action against bandits along the Chengdu-Chongqing Railway and decisively eliminate these bandits and the remnants of the Kuomintang. The Vanguard Company's mission is to eliminate the Mountain Trolls and the Kuomintang special envoy Li Muyang, who are entrenched in the Neijiang area. Deputy Company Commander Zhang Biao, taking advantage of being a local, disguised himself and went to gather information. Luo Xiang Qian, who stayed behind in the company, was very worried about Zhang Biao's safety and felt restless.

Wu Qiang advised him to calm down a bit, as the distance is quite long and it will take one or two days to travel. Just then, Zhang Biao, dressed as a farmer and covered in dust, burst in and immediately asked for water. Luo Xiang Qian and Wu Qiang quickly greeted him and asked him to sit down and talk about the reconnaissance situation.

Zhang Biao had already found out that the Mountain Trolls, led by Li Muyang, were huddled in a cave in Longtan with dozens of other bandits. Every two days, they would force a villager surnamed Fan in a nearby village to bring them food. Zhang Biao also checked the route that must be taken to attack Longtan and said that he would lead a group of soldiers disguised as villagers to charge in and eliminate them.

Wu Qiang and Luo Xiang Qian both believed that caution was necessary and that they needed to gather more detailed information before formulating a detailed battle plan in order to achieve success. Luo Xiang Qian personally went to see Old Fan and encouraged him to speak boldly about the situation in Longtan. Old Fan was worried that the Liberation Army would not be able to defeat the bandits and that the bandits would retaliate against him and his family, so he had some concerns.

Luo Xiang Qian assured him that the Liberation Army keeps its promises and that they will not withdraw without completely eliminating the bandits this time. Old Fan then provided detailed information about the Mountain Trolls to the soldiers. Luo Xiang Qian and everyone else immediately devised a battle plan to surround and eliminate the bandits.

When it was time for the attack on Longtan Cave, Zhang Biao and Luo Xiang Qian had a heated argument. In the end, Zhang Biao, being a local, successfully convinced Luo Xiang Qian.

Led by Old Fan, Zhang Biao and several local soldiers disguised themselves as villagers delivering provisions to the bandits. The Mountain Trolls didn't suspect anything when they heard Zhang Biao and the others speaking like locals. However, the cunning Li Muyang noticed something unusual and shouted that these people were all Liberation Army soldiers. He and his men retreated into the cave to resist.

Zhang Biao immediately led his soldiers to engage in a fierce battle with the bandits, while Luo Xiang Qian and the rest of the troops arrived soon after. With the powerful and energetic assault of the Vanguard Company, the Mountain Trolls and their subordinates were killed, but Li Muyang managed to escape. This operation to eliminate the bandits completely eradicated the Mountain Trolls' armed forces that had been entrenched in the Neijiang area for many years, laying the foundation for the safety of the Chengdu-Chongqing Railway.

Major Ma praised Luo Xiang Qian and the others on behalf of the superiors. The current phase of the road construction mission for the military engineering unit is to collect sleepers. The Vanguard Company was allocated 10,000 sleepers, but in order to surpass the Eighth Company, Luo Xiang Qian specifically requested an additional 20,000 sleepers from Major Ma.

After returning to the company, Luo Xiang Qian still felt some pressure. On one hand, there was the task of collecting sleepers, which had a tight deadline and was challenging. On the other hand, the work of building the roadbed could not be delayed. Wu Qiang found it amusing to see Luo Xiang Qian struggling and told him that as long as they relied on the local government and the people, they would be able to successfully complete the task of collecting sleepers.

The cadres of the Vanguard Company were assigned their tasks. Luo Xiang Qian and Zhang Biao led a group of people to collect sleepers, while Wu Qiang and Sha Kai stayed at the construction site to meet the deadline. After mobilization, the local military and civilians were filled with enthusiasm, actively participating in the collection of sleepers. The villagers donated coffins, wooden furniture, and other materials. During the collection process, Zhang Biao and his soldiers had a conflict with the local villagers. Luo Xiang Qian arrived in time to handle the situation properly and gained the positive support of the villagers.

In a very short period of time, the task of collecting 120,000 sleepers in the Neijiang area was completed. Along the entire railway line, a total of 1.2 million sleepers were successfully collected.
