Before Melgor took the gold coin out from his sleeve, Ren Xiaosu had never seen the currency of the Kingdom of Sorcerers before. This was because he had no need for it.
In some myths, coins were a representation of fate.
It was not that coins had some kind of special meaning to them but that people had a habit of tossing a coin to decide their fate.
For example, a person might toss a coin to decide whether to go left or right or whether to have supper or not. There were even examples of people tossing a coin to decide whether to be a good or bad person. Such decisions were made on a whim.
The tossed coin would ring pleasantly as it spun in midair, and by the time it landed, some people's fates would be decided.
Ren Xiaosu held the gold coin from Melgor and smiled without saying a word. So it turned out the people he was looking for were both on this coin.
Wasn't this such a coincidence?
