Although Zhang Lisheng was still trying to mystify things up by comparing the sand monster to a human and predicted the death of the spiritual monster, he would never imagine the Gold Core as a human heart.
After all, every native Chinese who was born and grew up in China knew that the mystical creatures had a complete set of organs, so it was impossible for the Gold Core to be their hearts.
However, if one looked at it from another perspective, the demon in the mythical legend would transform back to their original state if they lost the Gold Core. In other words, the animal demon would transform back into an animal beast while the tree demon would transform back into a tree.
