Khan struggled to understand for how long he fell. His proficiency with the Lightning-demon style had stepped on the competent level, granting him incredible agility and ability to preserve balance. However, he couldn't deploy those skills when the ground shattered as soon as his feet touched it.
The underground world of the regions filled with tunnels was incredibly frail. It turned out that only the surface had retained a stable structure, but everything under it had the same texture as thin glass. A simple impact was enough to make large patches shatter into countless pieces.
Khan failed to find a stable foothold multiple times as everything around him crumbled. Waterfalls made of dirt and ground fell together with him and clouded his vision. His eyes burnt, but he forced himself not to close them. He was worried about his situation, but he also hated how he couldn't get to his girlfriend falling only a few meters from him.
