The "Celestial Master Gold 天師金" is an exclusive magic series specially consecrated at the headquarter altar. Anyone can purchase these at a very affordable price and do any magic with these "preloaded" magical papers. In short, they serve like a prepaid credit card but instead of money it is the magical powers. All you need to do is to use them by writing your intentions on the back and then activate them by burning or slapping them depending on your situation. Read the 101 guide to learn how to use them!
