Merlin regarded the Frost Lord coldly. Unless he had no other choice, he would not break the seal on the fourth form of Darkness Eye. He knew that once the seal was opened, he would have to use the power of the Maxims to constantly suppress the fourth form of Darkness Eye. Once the power of the Maxims was exhausted, Merlin would no longer be able to suppress Darkness Eye.
Nevertheless, improving his body was also an important quest because if he succeeded in cultivating Glacier Country, Merlin would possess two types of special Pandora Demon Abilities. By then, even if Merlin was only able to wield its third form, Glacier Country would suppress everything in its surrounding when it descended. Should the opponent be too strong to be suppressed, his abilities would still be considerably weakened.
