Samuel did not know about what was going on, and that the city Lord had already returned. Instead, he was still venturing in the wilderness, hunting more monsters in order to gain much more energy.
Each and every time that he killed a monster that was in the middle stages of the nine star rank, he immediately refined the energy. That way, his strength continuously increased with each monster that he killed.
This rate of development was something that had never been experienced in this world before. And if someone really heard about this, they would definitely be completely shocked.
It was a good thing that Samuel decided not to use the energy to increase his own level. Otherwise, with the amount of energy that he had managed to gather till this time, he would have already reached the nine star rank, and perhaps might have already reached the peak stage of the nine star rank.
