They both reached the ninth floor, so they were ranked by time, with faster times earning higher ranks.
The reward for the ninth floor was a 41-speed Pet Launcher, which was an extremely premium item for an average Mutator.
Lin Shen wanted the Pet Launcher, but he was not very interested in the Crystal-based Creatures within the tower.
The nine Crystal-based Creatures inside the tower were not mutants, simply ordinary Crystal Bases.
They seemed so formidable only because each level of the tower was an environment most advantageous to them.
In such environments, their Strength could be maximized.
In those kinds of environments, even a Mutated Crystal Base may not necessarily be their match.
For instance, the second layer had a high-temperature environment, guarded by a Hot Rock Giant. The hotter the environment, the harder the body of the Hot Rock Giant became, and in such high temperatures, ordinary mutants couldn't defeat the Hot Rock Giant.
