The Eighteenth Route's campaign against Dong was not in harmony with the hearts of the princes, and they stood still. Dong Zhuo took the opportunity to coerce the emperor and moved his capital to Chang'an. One day during the banquet, Sikong and Zhang Wen were beheaded for no reason, and the civil and military officials of the Manchu Dynasty turned pale with horror.

Situ Wangyun wanted to get rid of Dong Zhuo, but he had no good plan. He was worried about state affairs and had trouble falling asleep, so he came to the garden alone and found the diva Diaochan sighing at the moon in the garden. When he learned that Diao Chan was worried about the people, he set up a "serial plan" with her: first marry Diao Chan to Lv Bu, and then offer it to Dong Zhuo, separating their father and son, and prompting Lv Bu to kill Dong Zhuo.

Lu Bu came back from hunting and met Diao Chan by the stream. He was intoxicated by seeing Diao Chan's beauty. Wang Yun invited Lu Bu to the mansion and promised to send Diao Chan to Lu Bu as a concubine. "Choose a good day sooner or later and send it to the general's residence."

Taking advantage of Lu Bu's chance to escort the chariots to Meiwu, Wang Yun offered Diao Chan to Dong Zhuo.
