Second and third senior brother with hearts as stifled as their big senior brother’s

Regarding the blood demon core, Song Shuhang had once speculated that it could be recharged using the blood bone or blood pearls. However, he'd never got the chance to try it out.

And now, with this prompt that he got from the beam of light, it appeared that his speculation was spot on.

When he took out the blood demon core, blood bone, and blood demon pearls, they were simultaneously enveloped by the beam of light. The beam of light was like a processing machine. After the raw materials were input, it began to work.

Under the influence of the beam of light, the power in the blood bone and blood demon pearls was extracted.

The blood demon pearls had a structure similar to spirit stones. They were a product of Senior White, and could be used directly. The blood bone was what remained after the unfortunate blood demon had died, and contained a special power that belonged exclusively to cosmic demons.
