West was in disbelief when he watched Lawrend ascend to become a Sub-God. He didn't know that Lawrend was just a Divine Mage. He saw the sea of laws that Lawrend used to create his own world. At this point, it was very clear that he was no match for him.
The truth of life hurt West. He grew up lacking talent. He even had to sacrifice the whole world just to become a Divine Mage. Talent was not something he had, but persistence he did.
Unfortunately for him, he couldn't become a Sub-God with just persistence. He did everything he could, but there was nothing he could do if becoming a Sub-God required talent.
Even that old man in the Human World became a Divine Mage on his own. It was so unfair, but West was confident that if he couldn't become a Sub-God, then no one else could. It was all true until Lawrend showed up.
He became powerful with great momentum and became a Sub-God right before his eyes.
