Episode 8 recap: Wu Liang was killed.

Guan Zhixuan and Peng Yingqi had just finished dinner when they saw a car speeding by. They quickly chased after it and called in some colleagues. The speeding car was stopped, and Peng Yingqi was asked to take a breathalyzer test, but she was not over the limit.Xu Guoxian met with Officer Dai and told him about Wu Liang's recent situation - Wu Liang was about to have a 5 million yuan transaction, and if they could catch him this time, Xu would no longer need to go undercover. Officer Dai told Xu to be careful.

When the time came for Wu Liang's transaction, Officer Dai was coordinating the operation, and Peng Yingqi's team had the area surrounded. Peng Yingqi was observing the situation from a building across the street with binoculars. They were waiting to catch Wu Liang red-handed. Wu Liang arrived with the money, and a child brought a bag of drugs. Xu Guoxian signaled that everything was ready, and Officer Dai told Peng Yingqi's team to move in.

Unexpectedly, Chen Zuoyao had already arrived across the street and tried to kill Wu Liang. The bullet hit the person doing the drug deal instead. Peng Yingqi's team rushed in, but Wu Liang managed to flee. Xu Guoxian tried to run away but was caught by Guan Zhixuan and Peng Yingqi.

A body was brought out of the building, and Peng Yingqi recognized it as Wu Liang. The forensic doctor, Dr. Fan, told Peng Yingqi that Wu Liang had been shot three times - twice in the legs with abrasions on the knees, likely to make him kneel, and the final shot to the forehead.

Peng Yingqi told Guan Zhixuan that she didn't think Xu Guoxian was the killer, because the first two shots and the final shot were separated by a time interval, suggesting the killer had a strong hatred for Wu Liang, which Xu Guoxian did not seem to have. The forensic doctor had also expressed a similar opinion.

The officers told Xu Guoxian to turn off the surveillance cameras. Xu Guoxian felt that now that Wu Liang was dead, he should be able to retire. Officer Dai asked Xu Guoxian to write down the address of Wu Liang's warehouse, as he would have someone investigate it. Guan Zhixuan's team went on patrol and discovered that Fanqie and his associates were about to make a transaction.

Fanqie gave the goods to Zhang Dong, saying it was a new product and asking Zhang Dong to give feedback after trying it. Lin Xueер came to the anti-crime unit, as Peng Yingqi had called her in - Wu Liang's last phone call before his death was to Lin Xueер, and there had also been two other calls in the past few days.

Lin Xueер said she did not know the person Peng Yingqi mentioned, but a real estate agent named Mr. Zhong had contacted her about looking at a house. It was Officer Dai's birthday, and Xu Guoxian gave him a brand new watch as a gift. Officer Dai said they had investigated the 7 locations Xu provided, and the total assets were only around 10 million, although it was reported that Wu Liang had 10 billion in assets.

Xu Guoxian wanted to be reinstated, but with his situation, he would first have to do a year of patrol duty before being allowed to transfer to the criminal investigation department. Xu Guoxian ran into Lin Xueер at a bar, as they were old classmates, and they had dinner and drinks together. As they were leaving, a group of people came to attack Lin Xueер, and Xu Guoxian pushed her away and fought with them. Lin Xueер quickly drove Xu Guoxian away.

Lin Xueер didn't know if she had offended someone, so she asked if she could stay with Xu Guoxian for a while. Xu Guoxian agreed, and when they got back, Lin Xueер locked the door, turned off her phone, and removed the SIM card.
