Why did Jun Chen hurt justice in a just way?

On the road of justice, Jun Chen hurt the cause of justice, because the Qin family hurt the people that Chen Jun cared about. According to relevant public information, the Qin family hurt people who care. Early the next morning, Zhu Baolai told Tianyi that the Yamato Hall had moved away. As soon as people arrived at the Yamato Hall, they saw Mingjuan and Sean's bodies being hung as soon as they entered the door. Xuan Ming cried with her sister Mingjuan in her arms. Tianyi recalled Sean's words: Don't save yourself, live a good life with Tianyi, and she burst into tears. Watanabe and others disguised themselves as ordinary people and went to Duolun with stolen treasures. Watanabe remembered that Tianyi had threatened himself, and now he was a little scared, so he dismounted and took the path, leaving Zhengcang to lead the team. Tianyi and others put Mingjuan and Chen Xiang's bodies in the Qin ancestral hall, and Tianyi took out the whistle she held tightly before she died and a small note written by Chen Xiang in blood.
