According to the original text: Xiao Li's flying knife was built by a blacksmith in Daye in two hours. It is three inches and seven minutes long and as thin as a cicada's wing. -You can make one every two hours. It can be said that this flying knife is unique in technology except for being thinner. The reason why it can rank third in the weapon spectrum is entirely because the person who uses this knife is Li Xunhuan.

As for the flying knife in Li Xunhuan's hand, it is described in the book as follows: Li Xunhuan once flew the knife 76 times, causing 5 1 person to die and 25 people to be injured. Although his flying knife is accurate, he has never killed anyone by mistake. 100% hit. As for whether the fatal blow takes effect, it depends on the target attribute. Xiao Li's flying knife can do this only because of its sharp weapon or high martial arts? Gu long has also given the answer: "no one knows where his flying knife is, and no one knows how it came from, in the sky and underground." No one can imagine the speed and strength of the knife before it is fired ... you will never find anyone to replace it.
