But gradually, his joy faded away. Although he was absorbing the Zombie Crystal Cores, he found that the Water Element Crystal Core he had devoured was gradually weakening. Since it wasn't a Crystal Core that he had awakened on his own, there was no way to strengthen it by absorbing Zombie Crystal Cores. The cores he absorbed could only slightly slow down the decay of the Water Element Crystal Core.

He tricked the young girl into going out to kill more superpower users, but when she agreed and returned, not only did she not bring back any superpower users' Crystal Cores, she also came back severely injured!
When he saw her tiny frame curled up in a filthy blanket, he was initially terrified. But soon after, that terror gradually dissipated, turning into greed.
