The ingredients contained in this hot spring have a significant skin-beautifying effect, and it has been famous since ancient times for giving you translucent, beautiful skin. So the owner of the inn came up with an idea to condense the skin-beautifying ingredients of the hot spring into a single pill and sell it as a supplement. When he actually made it and drank it, lo and behold! It really did make his body transparent, causing a commotion! This was the birth of a divine supplement that could only be sold on the dark web! If you drink this, you can do anything you want! You can have sex as much as you want! And no one will find out. Because he's invisible.
