The Blade Company secured the honor of launching the 100th missile. Xia Zhuo and his comrades rushed to the First Company's barracks to celebrate, enraging the First Company soldiers who doused them with buckets of water. While everyone reveled, Ouyang Jun remained somber. Political Instructor Shao Shuai urged him to wait until after the 100th missile launch, but Ouyang Jun couldn't bear the torment of rumors any longer. Ouyang Jun goes to the brigade headquarters and voluntarily admits his mistake to the political commissar. He deceived both his father and his superiors, hoping the brigade will discipline him. Due to the launch mission, the 270th Brigade needs to replace the launch vehicle. Lang Yongcheng is reluctant to see his beloved vehicle retire, growing more and more depressed each day. Lin Anbang and Xia Zhuo are deeply concerned.
