Roots & Dragon
As the fight progressed, the pull of the Cursed Seals grew stronger. Michael's insides felt like burning as the Cursed Seals demanded to be activated, their power unleashed, and their terror rapidly spreading through the Origin Expanse.
Since the day Michael learned more about the Cursed Seals, he could feel their presence within him more easily. He could manifest them at will and unleash their power at once. However, Michael didn't want to do that. It was not necessary to unleash the Cursed Seals. They were dangerous, and it was not unlikely that he would lose his mind mid-battle.
Michael was not willing to manifest the Cursed Seals if it was not desperately required, or if he was not in a safe environment to experiment and study the Cursed Seals.
The burning sensation of the Cursed Seals bothered him a little bit, but Michael didn't have any time to complain. He was focused on the situation ahead because he had underestimated the strength of his enemies.
