Chapter 432: Each Shows Their Ingenious Trick

This was the twentieth year since the Silkworm Demon Emperor returned from the Human Realm to the Spirit Realm.

Inside a luxurious Cave Mansion.

The ruddy-faced Silkworm Demon Emperor was counting Spirit Crystals in his hand before handing them to a man with snow-white skin and two antennae on his forehead.

"Black Butterfly Brother, this is your interest. A total of fifty thousand Spirit Crystals, ten years of investment, and that's five hundred Spirit Crystals. As for the principal sum, you'll have to wait a century before it can be turned around. You know that mining a Spirit Crystal Mine requires a huge initial investment."

The man, known as Black Butterfly, was a moth that had transformed into a demon after a million years of painstaking Cultivation, finally reaching the Demon Emperor Realm.
