While Sun Wukong was immersed in reading and sorting through thousands of books in the library, Dao of Heaven Eternal Coins were circulating widely throughout Huaguo Mountain.
The Dao of Heaven Eternal Coins were divided by Ao Yun into two main categories.
Dao of Heaven Coins and Eternal Coins.
Eternal Coins consist of black-patterned coins and red-patterned coins.
Dao of Heaven Coins are the silver-patterned coins and gold-patterned coins.
Among them, Eternal Coins were more common, while the number of gold-patterned and silver-patterned Dao of Heaven Coins was less, to prevent inflation, these coins, although also crafted in abundance by Ao Yun with the Cornucopia, were not released in large quantities.
However, despite the popularity of Eternal Coins and Dao of Heaven Coins, a problem became evident.
That was the convenience of circulation.
