After entering the sea, he successfully slaughtered two huge mystic-rank sea kings. This scared everyone in unit 18. Only then did they realize that Lin Xuan had already advanced from yellow-rank to mystic-rank, but he was also able to subdue sea kings now. Now that he had advanced to mystic-rank, killing mystic-rank was a piece of cake... What the h*ll!
It was not that they did not know how strong a mystic-rank was. After all, they had a good understanding of their own strength. They were also clear about the strength of the sea kings in the dungeon, although there would be errors between individuals, there was not much difference in their overall strength.
This was because the sea kings were huge, much bigger than the mystic-rank monsters in the real world. This also led to the difference in health, physique, and strength. The sea kings were much stronger. Moreover, the vast majority of the dungeon was in the sea.
