Before meeting May Su Chang, a dark organization in Japan was an aristocratic organization, belonging to the Japanese prince. On a secret mission, the prince died of negligence. This organization specializes in training children, teaching them all kinds of skills, and training all kinds of martial arts. It is regarded as a machine, which is born to perform tasks and controlled by special drugs.
Like Liu Fei, many of these children are poisoned by drugs. Years of drug poisoning led to mental retardation, so Liu Fei's intelligence remained at the childhood stage, which is why Liu Fei is so lovely.
When I met May Su Chang, Liu Fei was lying helpless in the street, and his insanity caused May Su Chang's pity. Therefore, Mei Su Chang took him back to Jiangzuomeng for adoption, and then Shao Ge, the owner of Langya Pavilion, helped Liu Fei to treat the disease and clean up all the toxins in his body. But his mental disability can't be restored to normal, so he looks silly and cute. As Mei's personal bodyguard, Liu Fei has the military function of defeating Xia Jianghe. Even if the Grand Commander Meng fights with him, it is difficult to subdue him, so it is not a problem for him to rank in the top 5 of Nirvana in Fire.
Abstract: Liu Fei's life experience was tragic, but he was very lucky to meet Mei Su Chang and Master Shao Ge like his brother. Liu Fei played by Leo is cute and naughty, and the trio of Jin Dong and Hugh is a very interesting combination.
Later, Liu Fei stayed in Langya Pavilion to accompany the owner of the small pavilion, because Mei Su Chang never came back after the war, which was a great pity. However, in the online drama version, Mei Su Chang did not die, but returned to Langya Mountain and Liu Fei to live with the owner of the small cabinet until she was old.
