The old policeman, Uncle Shi, revealed to Xu Xiao that Lin Guo emphasized that the reason behind the Municipal Public Security Bureau was that his daughter died unfortunately and his wife divorced him because of this.In order to change the environment, Lin Guoqiang applied to the organization and obtained approval from the province.But when Xu Xiao further asked Lin Guoqiang's daughter about the cause of death, Uncle Shi remained silent.

In order to obtain clues, Xu Xiao considered asking Chen Nan to try to communicate with Ding Dang.He brought Chen Nan to Lin Guoqiang's house. Chen Nan planned to use psychological skills to help Ding Dang recall the scene that night in order to find clues to the case.Lin Guoqiang was worried that doing so would cause greater harm to Ding Dang and hoped to proceed step by step, but Xu Xiao believed that the key was to catch the murderer as soon as possible.

With Chen Nan's help, Ding Dang began to recall, but her body felt uncomfortable due to excessive tension.Chen Nan expressed his admiration for Ding Dang's courage.Lin Guoqiang understood Ding Dang's emotional changes, after all, she had lived in the trunk with a broken body.Regarding the murderer's behavior, Xu Xiao speculated that the murderer might have had time to bury his body because he was eager to find his next target.

Chen Nan proposed to explore clues through scene reappearance, but Lin Guoqiang believed that this was too cruel to Ding Dang.Xu Xiao insisted that procrastination would only give the murderer more chances to commit the crime.In order to train Ding Dang's courage, Lin Guoqiang took her to the dim building to find the cat and took the opportunity to mention that the crime scene would be repeated to inspire her memory.

Ding Dang became dependent on Lin Guoqiang and wanted to continue to stay.Everyone quickly arranged to imitate the scene of Ding Dang being arrested, but Ding Dang did not recall any useful clues, and Xu Xiao was disappointed.Despite the success of several tests, Lin Guoqiang still hoped that Ding Dang would stay because he found that Ding Dang had begun to actively learn and make breakfast.

However, Xu Xiao was wary of Ding Dang and believed that it was dangerous for her to stay by her side.He mentioned Ding Dang's bad history in the past, pointing out that she was a lazy girl who was a lazy girl and might be Lin Guoqiang's next target.Lin Guoqiang didn't care about this, and even revealed that Ding Dang had confessed everything and secretly read his daughter's diary, knowing that he liked to eat dumplings filled with radish.Although Xu Xiao insisted that Ding Dang would not learn well, Lin Guoqiang decided to give Ding another chance out of fatherly love.
