Ray had too many skills to train on if he wanted to excel in his talents, yet he had no time for such luxury. He had six months for a way to kill the king of silence, yet he needed years and years of training. The answer came to him when he thought of parasite; he certainly stayed on a planet where time ran slower. Time itself didn't matter without resources to level up usually; however, he needed only time.
Going to space was an easy task for him, yet surviving on a bare planet with no life form was the hard part. Unlike Mars, Mercury had nothing for a human worth exploring, long days that could burn one human, and nights that froze to death.
Base stats only meant how strong he was; it barely had anything to do with his durability, which made the environment perfect for him to increase his physical conditions while training his magic.
