Sun and Moon Wasps

For the next six hours, Krune struggled like crazy as his hands began to shiver. Not only did he have to refine the spherical clay in the mysterious fire, but he also had to extract the excess essence generated from the village head, ensuring to not take any of his bloodline.

In other words, Krune required a lot of precise control, having no room for mistakes. Had Krune been younger, around 20-30 years old, this would have been a lot easier on him. Then again, it wasn't like he had such an option. 

Thus, he persisted stubbornly, finally beaming with a smile when the color of the flame changed once again. Throwing aside the tools, he used his hands, beginning to mold the clay-like substance. 

As the fire raged forth, the clay began to be compressed once again, gradually getting smaller and smaller. However, it still retained its original weight. So, Krune's hands were hurting a lot.
