To this day, Guan Hongyu has still not been able to reveal the true face of the mastermind behind the scenes, but he recalled the meeting between his brother Guan Hongfeng and Chi Wenjiang before his death, and he couldn't help but become suspicious of Chi Wenjiang.Qu Xian advised Guan Hongyu to calmly reflect on whether there were other incidents between Guan Hongfeng and Chi Wenjiang's meeting and his death.After repeated verification, Quxian confirmed that Chi Wenjiang had no connection with criminal organizations.

Qu Xian was willing to risk his life to guarantee Chi Wenjiang's innocence, and was deeply saddened by Guan Hongfeng's sacrifice, which also caused ripples in Guan Hongyu's heart.Later, Guan Hongyu returned to the police station as his brother, proposed his resignation to Zheng Qi, and handed over all the information he obtained from his investigation.He went to the forensic examination room alone, while Han Bin watched silently.

Guan Hongyu endured his grief and uncovered the white cloth, and found that the brothers' secret gestures were hidden in his brother's burnt hands. This gesture guided him that the mastermind behind the scenes was Shi Guangling.Zheng Qi quickly reported to his superiors and worked hard to get reinstatement for the Changfeng detachment.

At the same time, all members of the detachment acted quickly to arrest him.Qu Xian prepared a pistol for Guan Hongyu.In the end, Wei Dong, Wang Mingzhen and others were arrested one after another.Shi Guangling met Guan Hongyu by chance while shopping with his wife. Guan Hongyu took the opportunity to test Shi Guangling, and Shi Guangling exposed his flaws.Faced with this scene, Shi Guangling simply took off his disguise, but Guan Hongyu was attacked by his men and fainted.

In another scene, Babyface found a pistol from Guan Hongyu. Shi Guangling used the gun to threaten Guan Hongyu and claimed that his son Guan Taotie was in his hands.Because Zhou Xun was unable to contact Guan Hongyu, Zheng Qi took the risk to sign the gun application form and went to the city bureau to seek support.Before leaving, he handed over the deployment power to Zhou Xun and emphasized two major principles: one is to protect the children and “Guan Hongfeng”, and the other is to catch all the bad guys.

At Guan Hongyu's request, Shi Guangling had someone bring the child.Guan Hongyu looked at his son excitedly and kissed his cheek.However, Shi Guangling ordered his men to abandon the child after getting the USB flash drive.

That night, everyone gathered at Huixiang Temple, and Shi Guangling took Guan Hongyu away alone.He knew that Guan Hongyu was deceitful, but he didn't care. As long as the people who knew the whereabouts of the USB flash drive were eliminated, no one would know his secret.

Guan Hongyu heard Shi Guangling's intention. It turned out that he asked Ni Jun to get the USB flash drive just as a pretense. In fact, he put the bomb in the cabinet to attract the attention of the police.Ni Jun was surrounded by the police as soon as he completed the arrangement. Shi Guangling thought that the plan was perfect, but he did not expect that it was Zheng Qi who answered the phone.

Shi Guangling thought he could control Guan Hongyu with the child in his hands, but he didn't know that Qu Xian had rescued the child, and his high-tech methods were also cracked by the detachment's technical department.It turned out that Guan Hongyu secretly placed the locator while kissing the child, and Quxian found the child accordingly.

At this time, there was loud gunfire outside. Shi Guangling was shocked and wanted to shoot, but found that the magazine was empty. It turned out that the bullet had a location hidden in it.Guan Hongyu originally planned to sacrifice himself. Even if Shi Guangling did not shoot, he would use this gun to end Shi Guangling's life.

Zhou Shutong and Shang Kai fought fiercely, and others arrived in time.Zhou Shutong rescued Guan Hongyu and shot Shi Guangling to death.Guan Hongyu broke free, was injured and pursued Shang Kai to the rooftop.He originally wanted to use the steel string to avenge his brother, but he remembered his brother's teachings and finally gave up.

In the end, Shi Guangling's gang and its illegal members were severely punished by law.Zhou Xun and Guan Hongyu stood on the rooftop and analyzed the reason why Guan Hongfeng's call was interrupted.It is Zhou Xun's great fortune to work with Pun.Guan Hongyu paid homage to his brother's tomb, and Guan Hongyu's name was engraved on the tombstone, but he will continue to move forward as his brother, pursuing justice and fairness.
