Great Earthen Wall

A huge wall rose from the earth. It was many miles thick and tall, and it spread through the battlefield. 
Countless runes floated across the wall. Thanks to the runes, the earthen wall actually gave off a metallic luster. A heavy aura came from it that made it seem like an invincible city wall.
Long Chen smiled. After becoming rank nine Celestials, Li Qi and Song Mingyuan's earth energy had grown even purer. This wall's defensive power was startling.
Countless Golden Tail Underground Centipedes came crashing out of the ground. This wall didn't just seal the sky, it also sealed the ground beneath it. They were unable to pass.
