Pang Tianchong has been practicing martial arts in the mountains for nineteen years. Due to his unkindness, his master sent him to the city for training. When he first arrived in the city, he accidentally soiled the dress of Dai Qianxue, the president of Daikang Group. He was unable to pay the compensation, so he used his work to pay off the debt and became a security guard for the group. He used his strong skills to fight off bad people, met the old lady of the Luo family while helping others, and then found his lost family members. However, he learned that his father had been framed by the leader of the Zhuo Group. While guarding Dai Qianxue, Pang Tianchong investigated the truth and finally brought Zhuo and his son to justice. While spending time with Dai Qianxue day and night, the two gradually fell in love. In the end, when Pang Tianchong broke through the bottleneck of martial arts, he chose to stay in the world to protect his loved ones, and truly understood the warmth, warmth and true feelings of the world.
