The Eighth Weapon

When martial arts master Mr. Gu Long ranked martial arts weapons, he only listed seven types, leaving out a powerful and real weapon. Of course, this is not his fault, because that story has been submerged in the long river of history for more than a thousand years. It was not until the beginning of this century that an ancient artifact was accidentally unearthed, and that period of history came to light. Li Cunxiao, the best shot in the world, was defeated by another shot, shocking the government and the public. The resulting honesty and conspiracy, desirelessness and greed, kindness and cruelty, benevolence and hatred run through the story. Which one is right and which one is wrong? Please comment.
