Kill Someone in Ten Steps and Leave No Trace in a Thousand Miles

I have three swords, one is called the emperor's sword, the second is called the princes' sword, and the third is called the common people's sword. I have three paths, one is the king's path, the other is the minister's path, and the third is the chivalrous path. The Emperor's Sword lays down millions of corpses and bleeds thousands of miles, which is the way of kingship. Use the sword of the princes to conquer cities and territories, serve the country with loyalty, and serve as a minister. The commoner's sword can kill people in ten steps and leave no one behind for thousands of miles. This is the way of chivalry.
