The crushing pressure kept smashing Cain's mind and spirit, urging him to rest, but he knew that if he did that for even a second, his mind would turn off and he would never wake up, so no matter what, he kept resisting.
Hours went by, and Cain's body trembled more and more, his entire body soaked in cold sweat as blood leaked from his ears, eyes, nose, and mouth. No matter how painful and exhausting it was, he kept enduring, every second his willpower growing larger and the evolution advancing.
After thirty hours, the last wisp of that metallic gray fire vanished inside Cain, only for a willpower that burned like a sun to emerge from his eyes the next second, and inside the power to hold an entire world could be felt.
Cain's eyes glowed with such intensity that it felt as if they could replace the light of the sun in the sky. He raised his hand and gently clenched his fist, immediately causing cracks to appear in the fabric of space around him.
