บท 163: Mysterious System

Rain was in awe of what had just happened.

He had never experienced anything like it before, and he was struggling to make sense of the incredible surge of power that had flowed through his body.

As the warm glow faded, he looked down at his hands, which had been subtly transformed by the energy.

He flexed his fingers experimentally, marveling at how strong and nimble they felt.

"Wow," he breathed, "I can't believe it. I actually reached B-rank." 

According to his estimations, it would have took around one or two months to make a breakthrough. 

"I guess now I can explore the island more and quickly leave it." 

A feeling of pride and accomplishment welled up within him, washing away the last remnants of doubt and fear that had been holding him back.

For so long, he had felt weak and helpless, trapped on this isolated island with no hope of escape.
