Qin Xiaotian, the son of Qin Shiming, the former boss of the Great World, returned to the Great World three years after he was released from prison. He wanted to find out the truth about the tragic death of his parents. In the process, he found his lost brothers and sisters one by one, wanting to avenge his parents together. Only the third sister Xuehua believed that we should not take revenge on each other, but should focus on the overall situation. When the country and the nation are in danger, we should not only have personal grudges. Revenge began. Seeing his family being hurt because of hatred, Qin Xiaotian felt more and more strongly that his original intention was wrong. His younger brothers Xiaowu, Xiaowen and others failed to give up hatred after all. Qin Xiaotian was desperate, and Xuehua encouraged his brother to let go of hatred and do meaningful things for the country and the nation. When the Anti-Japanese War broke out, Qin Xiaotian faced the muzzle of the gun on the battlefield and rescued the wounded, hoping to let his younger brothers and sisters let go of hatred and join hands to fight against the invaders. The Qin brothers and sisters finally understood their brother, let go of hatred, and joined forces with their former enemies to resist foreign enemies.
