Linglong heart is a plot prop. Generally speaking, useless things, put in dry handbags, can play a direct role without being embedded in clothes. Not every gem can be put into a dry Kun bag. If you want to put gems, you need to synthesize them with rain flower stones (if you want to put higher-grade gems, you need to put higher-grade rain flower stones (that is, synthesize three five-color rain flower stones). In addition, every piece of jade is put into a treasure. Refined in a pot (depending on personal luck, I got a gem at random). I have already exploded that little treasure box you mentioned. The other three kinds of five-color rain flower stones have never been heard of = the higher the grade of nine-color rain flower stones, the better the gems you get.
