Three years ago, the entire northern reconnaissance company was wiped out. The only survivor, Zhou Chenfeng, was publicly accused of being a deserter, his military badges were smashed, and he was demoted to the baggage train. He endured the humiliation and secretly collected evidence from old cases. Three years later, during an encounter, he led a baggage team to accidentally capture the enemy's frontline headquarters and intercepted a batch of encrypted documents and a military ledger. The account book clearly recorded the details of the betrayal of the company's position - the betrayer was actually the quartermaster Zhao Wujiu, and the acquiescence was the current division commander Han Xiao. Zhou Chenfeng did not say anything, but used the captured code book to pass a false information to the commander of the First Division Shen Tieyi, leading the main enemy force into the encirclement. Shen Tieyi saw Zhou Chenfeng's name on the battle merit list, brought up the old matter again, and demanded a thorough investigation. Zhao Wujiu jumped over the wall and tried to destroy the account books, but was nailed to death by military doctor Liu Jinghong using the remaining arrow clusters and poison samples from that year. When confronted in public, Zhou Chenfeng tore open his clothes, revealing the penetrating wound on his chest - it was the result of the 'transfer order' signed by Zhao Wujiu himself. Han Xiao collapsed on the spot, Shen Tieyi broke the tea cup and announced that Zhou Chenfeng was promoted to division commander. But Bai Zhi, the captured enemy intelligence officer, said softly during the escort: 'The account book is just the first page. You don't want to know who is supplying Zhao Wujiu behind the scenes? ' Zhou Chenfeng's pupils shrank suddenly—the end he thought was just the beginning of another war.
