Mu Xing's thoughts were simple; Ma Rude couldn't protect his family with his own abilities, so he could only rely on the slight advantage he gained when he initially surrendered, hoping that it would be enough to protect the Ma Family in the future.
However, this premise required that Ma Rude should not continue to make mistakes. If he stubbornly persisted in his current path, it would eventually endanger his family, and by that time, even if he were willing, Mu Xing would be powerless.
Mu Xing wanted to follow and find Ma Rude's residence so that he could persuade him to admit his guilt and try to reduce his punishment. However, when he found Ma Rude, instead of talking, Ma Rude tried to kill him immediately, and Mu Xing barely escaped with his life.
After listening, Su Xinyi looked at Mu Xing, whose expression was full of sorrow. She thought it was best to let him think it over by himself.
