Xu's fortune telling

In which episode of Infiltration did Lao Yang defect?

Infiltrating Lao Yang is not betrayal. Lao Yang has always been loyal to the Party and has never defected. Xu Zhongyi entered the hidden underground fortifications of Qi Gongzi alone, and fought with Qi Gongzi. Xu Zhongyi was soon at a disadvantage. Immediately, the two men raised their guns and formed a stalemate. As Xu Zhongyi persuaded Qi Gongzi to face the reality, he handed over the infiltration plan.

Zhao suddenly arrived and shot him from behind. Zhao Zhi pulled up Qi Gongzi and turned to flee. Xu Zhongyi, who fell to the ground, shot hard and killed Zhao Zhi. At this critical juncture, Yang Kecheng and Gu arrived with a group of soldiers, killed Qi Gongzi, and finally intercepted the infiltration plan.

Infiltration finale

Xu Zhongyi finally got together with Gu. In the infiltration finale, Gu was heartbroken after being injured. After learning that Xu Zhongyi might spend the rest of his life in a wheelchair, he decided to stay with him. In the end, Sha Yi and Yu Yue are a pair of "tell the judge" and "comrades in arms in distress". After many hardships, everything will be fine.
