Lin Chen, once the captain of China's top special forces "Dragon Teeth", codenamed "Lone Wolf", was a king of soldiers who frightened the enemy. His fighting skills and reconnaissance skills were second to none in the army. The person he trusted the most was his comrade and brother who lived and died together - Zhao Feng, codenamed "Falcon". The two worked together in a tacit understanding and had completed countless impossible tasks together. They were the golden partner envied by everyone in the army.
However, a top-secret mission codenamed "Thunder" completely shattered this brotherhood. During the mission, Lin Chen encountered a fatal betrayal and the whole team was wiped out. He was the only one who survived, but was falsely accused of treason and was seriously injured and ruined. He was forced to retire from the army and returned to the city incognito. While avoiding pursuit, he secretly traced the truth about the betrayer and vowed to avenge his dead brother.,,,,,
