When Ye Feng crossed the 20,000-meter platform, sprinting toward the 30,000-meter mark, he immediately realized that the difficulty had changed again.
Here, there was still the pressure of gravity and spiritual power, but in addition, there was now an attack from Wind Blades.
The strength of these oncoming Wind Blades was almost equivalent to an attack unleashed by a Fourth Order Wind Superpowered Being.
Although such attacks were still not much of a challenge for Sixth Order Prowess who could reach this point, the problem was that the Wind Blades were too dense.
These Wind Blades seemed endless, circling around Rule Mountain. A normal person would encounter an attack from a Wind Blade every meter they advanced.
Under such dense attacks, even Sixth Order Evolvers would undoubtedly face a tremendous burden.
