Shen Qiyun, the daughter of a wealthy family, changed her surname to "Lin" to participate in the competition in a low-key manner, and reached the finals with her almost miraculous swordsmanship. Just before the championship night, her dark history of being banned from the competition was a hot topic, and the entire Internet denounced her as a "sports worm". Only the cold-faced coach Jiang Zhao silently wiped the blood off the tip of her sword. When her former mentor Qi Yan exerted pressure in the name of justice, her half-sister Lin Jiawei manipulated public opinion, retired handyman Chen Sui handed over the recording left by her mother, and reporter Zhou Tingzheng held original evidence that could subvert the entire fencing system - she finally understood that this was not a championship battle, but a fair trial that her mother had paid for with her life.
