After practicing in seclusion for ten years, "Ghost" Yunqing, the miracle doctor of Qingfeng Mountain, came down the mountain and came to Rongcheng in accordance with his mother's last wish. On her way down the mountain, Yunqing met the second young master of the Ye family for the first time, Ye Hannian, who was being chased by men in black, and she came to the rescue. Ye Hannian fell in love with Yun Qing at first sight. In a hurry, Ye Hannian didn't have time to ask Yun Qing's real name, and only remembered the birthmark on Yun Qing's neck. At the same time, Yunqing's grandmother, the old lady of the Yun family, forced Yunqing to fulfill her engagement in order to cling to the Ye family. Yunqing refused to break off the engagement, but the Yun family broke up her house and expelled her father.
