Feng Jin (played by Wang Gang) came to the Tianxia Escort Agency and spent a lot of money to hire Wang Zhenwei (played by Zhou Qunda) as a bodyguard, and the person he needed to protect was Feng Jin's goddaughter Shen Feiyan (played by Wu Xiaomin). Shen Feiyan's father Shen Rong (played by Ji Qilin) discovered that the moves used by Wang Zhenwei were the "Bawang Soul-Chasing Gun" that he had been pursuing for decades, so he invited Wang Zhenwei's father Wang Zhaoxing (played by Jiang David) to come to his house for a gathering. Who knew that the two had unclear grievances before, and they unexpectedly agreed to compete in martial arts at Shilipo. On the day of the competition, Shen Rong fell under Wang Zhaoxing's soul-chasing gun, and what puzzled Wang Zhaoxing was that his gun did not hit Shen Rong, which meant that someone was interfering and killing people with a borrowed knife. Wang Zhenwei protected his father's escape and surrendered himself because he firmly believed that his upright father would never do such a thing. Wang Zhenwei was thrown into jail, but fortunately he was rescued by Shen Feiyan and regained his freedom. He then began to investigate the truth of the incident.
