White Clothes and Broken Blades

Everyone knows that the swordsmen in the dark night kill ruthlessly, but little do they know that in a corner of the island, there is an old friend in white who has retired to seclusion. He holds a razor in his hand that can cut hair in the world, and he has a hidden short blade that can cut through thousands of swords in the world. I originally wanted to stay away from disputes, mingle in the market, and live a stable life. However, the world is endlessly hunting, and grievances and grudges come to the door step by step. The white clothes rise again, and the broken blades come into being. This time, they are not for killing, but just to protect an island, wearing ordinary clothes.
