Hello! In this case, you'd better not take it, because the brave have the function of protecting you from disaster. If it has been fine and accidentally damaged a small piece, it means that you have fallen into a disaster, and your warrior helped you stop the disaster and was injured! As for how to preserve it: it's best to put it away in a small box and put it in a cupboard, because it can ward off evil spirits and attract wealth and can't be eroded by dirty air. Put it in Nanping or silk bags and put it in a clean place! I hope I can help you!
