What is the ending of "rival" Lin Biao?

Lin Biao's last mission was a success. He met a national treasure in the scenic spot, but in the end they were caught in the French Open. The national treasure turned out to be Meng Qiang, director of a military research institute, which is the biggest goal of spy organizations.

Lin Biao met with the national treasure to exchange the last information, and Lin Biao disappeared. Finally, Li Tang guessed Lin Biao's foothold: it was about 20 minutes' drive from the place where he called, and the background sound of the phone was bus No.28. Duan Yingjiu found Bao Hua Garden according to the only clues, and found Lin Biao and Huashu Hotel by looking for street cameras.

Plot introduction:

Lin Yao threatened Li Tang with Li Xiaoman's life at the last minute. He always knew that Li Xiaoman was his own daughter, but he didn't care about this blood relationship.

A video recorded by Li Xiaoman defeated Li Tang's psychological defense. At the moment Duan Yingjiu brought me Li Xiaoman's videos and cases, I fully understood who could really help me, not Lin Yan and the cruel hand behind him, but Duan Yingjiu, Ding Xiaohe and Xiamen National Security Bureau. These people are broad-minded and so noble. I want to confess everything.
