Lu Han traveled to the Qin Dynasty and became an unpopular prince. The old aristocratic forces headed by the prime minister obstructed him at every turn for fear of damaging their interests. At this time, the border war was urgent and the Qin State was facing a crisis. Lu Han needed to integrate all forces in a short period of time to deal with internal and external troubles. When promoting legal reforms, he was caught in a dilemma: whether to stick to modern legal concepts or compromise with the old aristocracy. At the same time, the strict hierarchical system and the exclusion of nobles restricted his actions. Some of the helper characters had misunderstandings with him due to their interests, and the attitude of the swinger characters made him in a dilemma in choosing his faction. Although Lu Han finally successfully implemented reforms and stabilized the situation in Qin, he lost his close friends in the power struggle and his victory was full of bitterness.
