He's Cultivating?

Klaus continued to revel in the feeling that he almost forgot about the test as a whole. He quickly realized that if he wanted more benefits, then he needed to increase the quality of cold entering his body. Without a second thought, the lights on the carvings, which had stopped on the Seventh floor for almost a minute, soared. From the Seventh floor all the way to the Tenth floor in nothing more than a second.

"How's this possible?!"

A young lady closed her mouth in shock. It's not that getting to the Tenth floor was impossible, after all, multiple people have achieved that today. What was crazy was how Klaus suddenly went from the Seventh to the Tenth floor in an instant was unheard of.
