Ye Ying, an ordinary modern person, traveled back to the Ming Dynasty due to a car accident and possessed a young Taoist priest from Longhu Mountain. On the way down the mountain, he rescued the proprietress Nan Shengjin who also traveled through time, and the two relied on each other in a strange era. They rescued Zhu Xiongying, and later because of the cure of Queen Ma, Ye Ying and Nan Shengjin were granted marriage by Zhu Yuanzhang. After getting married, Yeying was well aware of the shortcomings of the Ming Dynasty, and he and Nan Shengjin were determined to use modern knowledge and technology to reform. However, the powerful factions obstructed them in every possible way due to their damaged interests. Yeying is faced with a dilemma: whether to abandon the bottom line and make radical reforms, or to stick to principles and advance steadily. He chose the latter, but lost his best friend. Under heavy pressure, Ye Ying relied on his firm belief to lead everyone to compete with the powerful, and finally succeeded in changing the Ming Dynasty. After his success, he and Nan Shengjin retired to Taoism to enjoy peace and quiet.
