Episode 23 recap: Ji Dan Yang learned that his senior brother was murdered.

Bai Ming Han arrived at the warehouse but did not see Xue Lang in person. Xue Lang only contacted him through the phone. Xue Lang provided a code number, but Bai Ming Han felt that he couldn't just trust him based on that. Xue Lang claimed to have a higher rank than him and that he should simply follow orders, otherwise both he and his daughter would be in danger.

Bai Ming Han returned home and discovered that Bai Hui was not there, causing him great worry. Bai Hui and Zhang Ling went shopping and returned, mentioning that they brought something for Bai Ming Han. Bai Ming Han stated that if Bai Hui goes out, she must inform him.

Pang Hong Mei had a meal with Ji Dan Yang. Initially, she thought Ji Dan Yang had lost, but to her surprise, he had actually won, saving the project at least three years of time. Pang Hong Mei was also excited, realizing how capable Ji Dan Yang was. Previously, when she was in Hong Kong, she only wanted to complete the mission as soon as possible. Now, Ji Dan Yang appeared as a hero in her eyes, and all the grievances she had suffered before seemed unimportant.

Bai Hui also joined them and admitted she didn't know she had to be so concerned about others. Ji Dan Yang said that she should manage them the way her previous leaders managed her. The new nurses arrived, and Bai Hui explained the regulations to them. Luo Shanshan saw this and felt that Bai Hui had become strict, and she didn't even recognize her anymore.

Bai Hui expressed that if she wasn't strict with these people coming here, how could she manage them? They were still good friends, but things were different now. Pang Hong Mei and the others investigated in the workshop and found that the improper insertion of the steel wire rope caused the accident. Now, everyone in the workshop knows how to properly insert it. Pang Hong Mei noticed that someone was particularly skilled at it and believed that not everyone could do it so proficiently. They decided to investigate this aspect and found a total of 16 people.

Master Yang is a lathe worker, but he had previously won a championship in steel wire rope handling. It was confirmed that on that day, he was drinking at a fellow villager's place. They also examined the substance on the knife, which turned out to be a coolant. The footprints on the windowsill matched the size of Master Yang, which was size 42.

Pang Hong Mei came to find Master Yang, and Master Yang mentioned that Old Huo also joined them for drinks as they were all fellow villagers.

He Xi Wen had been locking herself in her room, and everyone thought she was emotionally affected. Ji Dan Yang brought roasted sweet potatoes to her. However, He Xi Wen was actually continuing her research, feeling that she couldn't fall behind. Pang Hong Mei discussed the investigation with Captain Chen, and he advised her to be mindful of her approach and not to undermine the workers' enthusiasm.

Wu Rui had injured his arm before, but now he was fine and could be discharged from the hospital. Someone came to inform that Wu Rui had an accident, and Bai Hui, who was receiving an intravenous drip, overheard it. Wu Rui took acetylene to make a lamp and went to the river to catch shrimp but got carried away by the current. Wu Rui explained that it was a common practice in their area, and he wanted to show filial piety to Master Niu, who loved eating shrimp.

Master Niu came up with the idea of using explosives for welding, and it proved to be effective. Pang Hong Mei reminded them to be cautious and ensure the proper quantity of explosives. They were now going to conduct a sealed cabin experiment, and He Xi Wen wanted to go in herself, believing she was the most suitable candidate. Ji Dan Yang brought a bracelet to Pang Hong Mei, promising to return her a string of beads.

Zhang Yan informed Ji Dan Yang that his senior brother was killed in the United States. Ji Dan Yang was deeply affected by the news and immersed himself in work, leaving Pang Hong Mei and others unable to help him. They all gathered in the workshop as they were about to conduct the sealed cabin experiment. He Xi Wen expressed her desire to go in, and Chu Gong agreed.

Bai Hui and her team were also present to provide medical services. He Xi Wen entered the sealed cabin, and according to the current data, she could stay inside for an hour and a half. Everyone was very nervous.
