After the Black Dragon rolled to the South, it rolled to the North. The North was where li Xianyu and the others were.
Because of its huge size, it was difficult for it to get up again after falling down, because the time it took to get up was enough for li Xianyu and the others to escape.
Moreover, rolling and killing people with his body was much better than using his ability to kill. The pain was like personally crushing a plastic bubble.
BOOM!
The earth cracked, and walls made of soil and stone Rose up, blocking the Black Dragon's path.
Tian Hao's eyes were bloodshot. With his ability, he had to erect a wall that could be used as a dam to stop a giant dragon that was nearly 200 meters long. It was very exhausting.
But fortunately, he was not alone. The storm had turned into hailstones, and they were burning in pain as they hit him.
