『Ding! Congratulation. You have killed 300 Children of Nightmare』
『Obtained 3 thousand units of dark energy.』
As Roy read the words that scrolled across his screen, his heart swelled with joy. He had earned 3 thousand units of dark energy, a reward well-deserved for his hard-fought battles against the insidious denizens of this dark and twisted realm. This much could be converted into 300 units of mental energy.
Previously, he didn't understand its value, but after the talk with the Obsidian Overlord in the World of Nightmare, he realized how valuable it was.
Mental energy was another name for the Power of the Sun and Moon.
It could be used to wipe out the consciousness of a power with a weak soul!
He couldn't use it as he was yet to open his sea of consciousness. But he already had a method to open it. It was mentioned in the secret tome.
『Earned a low-level resistance against the pull of Nightmare』
