Five years ago, in order to repay Jiang's father for adopting him, Jiang Xiaobei was imprisoned for Jiang Tian's crime. Jiang's father promised that he would help take care of his fiancée. Five years later, Jiang Xiaobei became a war lord. When he returned, he found that his fiancée Qin Muxue had become infamous and was kicked out of the Jiang family. Jiang Xiaobei investigated and learned that Jiang Tian coveted Qin Muxue's beauty, and if he couldn't get it, he spread rumors and slandered Qin Muxue for having an affair. Jiang Xiaobei made a strong comeback. He wanted to prepare the most luxurious wedding for Qin Muxue. He concealed his identity, designed wedding dresses and bought luxury cars along the way. He was ridiculed many times because of his simple clothes, but he took revenge on them all. Finally, in front of the city's dignitaries, Jiang Xiaobei explained the truth of the day and severely punished the Jiang family. Amid the cheers of the crowd, Jiang Xiaobei and Qin Muxue embraced each other deeply and promised to spend their lives together.
