Episode 7 recap: The latest developments on the driver responsible for the car accident involving Liu Xiao Yu.

Tan Jing Tian has fully disclosed his suspicions regarding Tan Jing Tian. He suspects Professor Tang because as his long-time mentor and student, Professor Tang would be familiar with Liu Xiao Yu's daily habits. The only person who could provide an alibi for Professor Tang that night is his wife, Li Guo, but given their relationship, such an alibi would not be considered credible.

Moreover, as a acquaintance of Professor Tang, it would not be surprising for him to enter Jilayou's home freely. However, Tan Jing Tian currently does not have any direct or indirect evidence to implicate Professor Tang, so he has had to let him return to China first. Tan Jing Tian also cannot understand why an entomology professor would want to harm Jilayou.

After returning to China, Tan Jing Tian was picked up by a police officer friend and went to the crime scene. Whether at home or abroad, Tan Jing Tian can use his expertise to help the police solve cases.

A famous local sculptor, Lin Meifeng, was stung to death by bees. Lin Meifeng had been raising bees and creating beehive sculptures for many years, so Tan Jing Tian believes he would have understood bee behavior and should not have been attacked by them. Tan Jing Tian went directly into the beehive without any protective gear and emerged unharmed, shocking the police but reassuring them after his explanation.

It seems Lin Meifeng was not wearing any protection because the bees would not harm him. Based on the information provided by Lin Meifeng's wife, the police chief Ru realized there were suspicious circumstances, and it appears to be a premeditated murder. Lin Meifeng's wife said that during their wedding photo shoot a month ago, Lin Meifeng had been stung by bees but was fine after simple treatment.

Following her account, Tan Jing Tian had the police officer Xiao take him around the area, worried that evidence may have been disturbed. Tan Jing Tian did make an important discovery - a green veil. Lin Meifeng's wife confirmed he was color blind, and the green veil was the only one at the scene, strongly suggesting this was a premeditated murder, shocking his wife.

The lighting lamps in the death scene tent were covered with green cloth, the friend of the wife of Lin Meifeng confirmed that all the lamps in the tents at the scene were covered with red cloth. Because bees are red-blind, and according to their habits, they need to be fed at night, so all the lamps need to be covered with red cloth, because red light is black to the bees and will not disturb them.

If the cloth was changed in color, when the deceased went to see the bees at night and turned on the light, it is easy to imagine that the bees would be disturbed. But the deceased did not notice the abnormality of the lamp cover cloth because he was color blind.

The investigation into Jiravu's social relationships revealed new information - Jiravu was a profligate scoundrel who used his family's wealth and painting skills to attract many young girls, even to the extent that some girls committed suicide because of him. Therefore, Jiravu's death this time was very likely an act of revenge.

The new information they discovered was that Tina, the daughter of Wen Ren who hit and killed Liu Xiao Yu, was once a student of Jiravu, and the two had a relationship. Later, Tina discovered that Jiravu was dating multiple girls at the same time, and she was deeply heartbroken, eventually committing suicide at home. The coincidences were too much - Wen Ren and Jiravu had a grudge, and Wen Ren had mistakenly hit and killed Liu Xiao Yu, there must be a connection here.

However, on the night Jiravu died, Wen Ren was working at the night market and many people could provide him with an alibi. The detective decided to arrest Wen Ren first, but when Wen Ren was being questioned, he was very surprised about Jiravu's death and felt it was his retribution. The detective and the investigator were about to believe him, until a video from Wen Ren's phone on the night of Jiravu's death was discovered, and then they realized they had been deceived by Wen Ren.
