"It turns out that levels do not represent the power one possesses, just like my Invisibility Rune. Although it is a fourth-tier skill, it lacks the might expected of a fourth-tier skill.

However, for combat skills, the level system should still serve as a measurement," Zhang Chen thought, as a Jade Talisman appeared in his palm, and in the next moment his figure disappeared from the stone cavern, leaving Sparrowhawk beside him baffled.
Moving in an invisible state, Zhang Chen perceived the flow of air, which made him all the more satisfied: "Although the issues of air flow and dynamic collisions remain unresolved, as long as I'm not in a crowded place, it's not a big problem."
