After the other party explained what "Yun" was all about, he almost didn't hesitate to join.
The imperial court had killed the entire Si family, including his own family. With such a deep-seated grudge, how could he not seek revenge?
Once he joined "Yun," he dedicated himself entirely to planning for his master. During that time, "Yun" had grown significantly, and he successfully secured an opportunity to carry out a mission in the capital city.
The plan to expand the "Yun" faction to the capital city was, in fact, his idea. Initially, Master Yun only wanted to tighten his grip on his own territory, but ambitious men couldn't resist the temptation of power. Eventually, Master Yun wavered.
Over the course of a year or so, their power had been developing smoothly, and no one even knew about the existence of such a clandestine force in the capital city.
