In the process of carrying out the task, Zhu Ziming was unfortunately captured. During the trial, Zhu Ziming finally chickened out and defected. He became the devil's inside man and returned to the independent regiment.

Finally, internal and external collusion with the Japanese army destroyed the Li Yunlong Independent Regiment and killed 300 innocent villagers in Zhaojiayu. Later, when he followed Yamamoto's secret service team to Ping 'an County, he was stopped by Chu Yunfei, 358th Regiment of Jinsui Army, and was asked by Yamamoto to take part in the battle. While climbing, he was killed by other secret service members who fell off the rope.

Bright sword finale plot:

Shortly after Li Yunlong returned to the Nanjing Military Academy, he and Kong Jie and Ding Wei had some opinions about the superior leaders because of the title problem, so they didn't change their uniforms when they assembled. The dean severely criticized three people, who admitted their mistakes and asked to participate in the National Day military parade after completing their graduation thesis. Kong Jie talked about the Korean War when he was writing his paper, and he was deeply moved. All three generals were lost in thought.

Finally, Li Yunlong decided the title of his thesis: On Soldiers' Fighting Will-Spirit of Sword. Li Yunlong's thesis was well received by the college. On the eve of graduation, he was awarded the rank of Major General, Medal of Independence and Freedom, Medal of Bayi and Medal of Liberation. At the military parade in Tiananmen Square, Li Yunlong and his comrades slowly raised their right hands to salute the military flag.
