Under Qu Jianghe's pressing step by step, Qiu Jianshe finally let go. Qu Jianghe chased after the victory, saying that he had caught Zhao Mingliang. But Qiu Jianshe was full of disbelief, because he thought it was impossible for the police to catch him. Qu Jianghe took the opportunity to shout, trying to break Qiu Jianshe's psychological defense. But at this moment, Qu Jianghe's daughter, Qiyue, called and said anxiously that Grandpa was missing.
After work, Qu Jianghe hurried back. At the same time, Qiyue and Meng Chuansheng were also looking around the community. The three met in the square, and then found Qu Jianghe's father among a bunch of uncles and aunts. Qu's father proposed to hire a nanny to cook at home, so that he can come out and dance square dances as he likes. Meng Chuansheng agreed and said he would pay for it. Qu Jianghe quickly refused, saying that the nanny fee should be paid by himself.
Seeing Zhao Mingliang leave, Sheng Liya quietly sneaked into his house, as if looking for something. Unexpectedly, Zhao Mingliang turned back suddenly and took something from the safe. Here, Yan Ge called Qu Jianghe, asked about Qiu Jianshe, and asked him to prepare himself for the investigation. Qu Jianghe was giggling, and promised Yan Ge that there would be progress within three days. Before he finished speaking, a strange phone call came in. The other party claimed to have a drawing from six years ago and invited Qu Jianghe to meet alone in the afternoon. Qu Jianghe wanted to ask something else, but the other party hung up the phone decisively.
Qu Jianghe hurriedly drove to the meeting place designated by the other party, but bumped into a tricycle on the way. He got out of the car to check, and found that it was Chen Chunfeng, the nanny who had just been hired, and her husband Luo Hai who had been hit. Qu Jianghe called 120, planning to go to the appointment first. But Luo Hai hugged his thigh and refused to let him go. Qu Jianghe had no choice but to let Zhuoyue come over.
Finally freed, Qu Jianghe hurriedly drove away. Walking halfway, he saw Zhao Mingliang's body with his own eyes. Here, before Qu Jianghe could figure out what was going on, he received a call saying that the provincial department had asked to release Qiu Jianshe. Qu Jianghe slammed on the accelerator and finally rushed back to the police station before Qiu Jianshe left. He wanted to stop Qiu Jianshe, but Yan Ge stopped him.
After preliminary inspection, it was found that Zhao Mingliang's car rolled over due to brake failure, and there were a series of numbers written in blood inside the car. Whether this was man-made or an accident, and what this string of numbers meant, the police were at a loss for a while. After that, Qu Jianghe found Sun Jiaqiang again and revealed that Zhao Mingliang had died. Sun Jiaqiang frowned, but opened the door anyway. At this point, Sun Jiaqiang told Qu Jianghe what happened six years ago.
Six years ago, Sun Jiaqiang got the list of missing miners, but after a while, the list and files disappeared. After the incident, other miners at the construction site left Jinchuan City soon. After all these years, no family members came to her. Therefore, no one is sure whether there is anyone in the mine.
Zhuo Liang thought of Chen Chunfeng and Luo Hai, and suspected that they were holding Qu Jianghe back on purpose. But the address of Qu Jianghe's car crash is far from the place of Zhao Mingliang's car accident. Ma Xiaolu feels that the two incidents are not directly related. However, Zhuo Liang felt that all the coincidences were carefully arranged, and he always felt that the couple was not simple.
Qu Jianghe looked at the string of numbers, but couldn't figure it out after thinking about it. Just then, someone knocked on the door. Qu Jianghe opened the door and found that the person who came was a woman. He recognized the woman's eyes. It was the woman who had her purse stolen by a thief on the street that day.
