On the eve of the liberation, our party's "underground" worker Liu Kehao successfully infiltrated the Shenyang station of the Nationalist Party's Confidential Bureau. In Shenyang, Liu Kehao not only won the trust of the station chief Xu Yinchu with his extraordinary personal ability and charisma, but also captured the heart of "Military United Flower" Lin Jing. However, Liu Kehao was well aware of his identity and mission, so he always dodged and skillfully avoided Lin Jing's advances and pursuit.
