Zhao Lin, a retired special forces soldier, is now a secret agent and goes deep behind enemy lines alone. Leng Shuang, codenamed "Ice Blade", is a top female sniper who performs top-secret missions. The two met unexpectedly and were involved in a major arms smuggling case. Clues point to high-level traitors, and the truth is layer upon layer of mystery. From confrontation to joining forces, breaking out of life and death, pretending to be a couple and sneaking into the enemy camp. Fierce fighting at the pier, cargo ships jumping into the sea, and mountain village raids were all dangerous. Former comrades betrayed, trust collapsed, and the price was heavy. Capital chains, biological and chemical weapons, and international conspiracies emerged one after another. Ten winds and clouds, a sea of counterattacks, and two shadows will eventually pierce the darkness before dawn.
