Chapter 658: 604 studies four

Outside Black Castle, within a secluded timber yard, there was a square courtyard made of black rocks.

Li Chengyi carefully used stones coated with the powder of the Griffon Stone to build a special model that looked like a diamond but had an incredibly complex internal network of structures.

After thousands of tests, he finally recreated the special structure inside the Griffon's Heart.

And this was supposedly the key to the generation of electrical currents in the Griffon's Heart.

"What a marvelous structure...." Li Chengyi finally adhered a stone within the diamond, then stepped back to admire the asymmetrical yet harmonious special structure.

It was this structure that multiplied the electrical charge generated through friction.

Snowflakes fell from the sky, scattering on the ground around, landing on the surface of this wondrous structure.

But curiously, merely upon contact, the snowflakes began to melt as if they encountered heat.
