Skeletons

All the illusions could not be broken through by external forces, even with the help of the Clarity Stone. As Merlin rested, he realized that he had been in Darkness Void for a long time, and the Clarity Stone that was once the size of an egg, was gradually getting smaller.

This would mean that the strange scent that the Clarity Stone gave off would not be contained for long. Perhaps one day the Clarity Stone would be completely exhausted and by that time if Merlin could not rely on his own strength, he could have been lost in Darkness Void forever.

"Faith. I must have a strong sense of faith in order to combat obstacles and break through this illusion!"

This time, Merlin was more determined. The illusion was not that terrifying as it only affected him on a spiritual level. That was why no external forces would affect the illusion.

However, as long as he had a firm belief, no illusion could get to him.
