Shadow Game in Jiangcheng

In the neon-lit city of Jiangcheng, the birthplace of the national secret 'Deep Sea' project, foreign espionage organization 'Viper' sets its sights. Lu Zheng, leader of the National Security's 'Rock' operation team, infiltrates Jiangcheng as a journalist and forms a temporary partnership with Xia Wanxing, an intelligence officer disguised as a multinational PR director. From mutual suspicion to life-and-death trust, they work together to protect core researcher Shen Zhiyan. Lu Zheng discovers that his opponent is Chen Mo, a former police academy classmate now leading Viper in Jiangcheng, who turned rogue due to his father's wrongful case and is obsessed with surpassing him. Xia Wanxing is also trapped: her best friend Su Man is actually a Viper informant, and her brother's illness becomes leverage against her. Decrypting codes, rooting out moles, and thwarting assassinations, the team treads on thin ice. As the investigation deepens, the truth behind Xia Wanxing's father Xia Mingyuan's 'fake death' emerges—he is actually 'Old Gun', a mole within Viper. More shockingly, the identity of Viper's top leader 'Ghost' is linked to Jiangcheng Chamber of Commerce president Gao Tianyang and the deceased project initiator Zhang Jingzhi. Amid neon lights and silent gunfire, faith stands firm between life and death, as a final showdown over national secrets and personal fates unfolds in Jiangcheng.
