What can I get by killing Wei Zi's fire curse?

You have a certain chance to get it when you kill the highest day star. According to my personal experience, if no one or baby kneels, the chance is higher, especially if you can't see it (that is, it is higher than 15, find someone to demonstrate how to kill it). Among them, the wooden elephant-the highest day star, the golden elephant-the earth star, the earth elephant-the four elephants of the true king, and the fire elephant-the ghost of the underworld? , water symbol-Daoxing (that is, 28 stars).
