"Rumble..."
At the very center of the crimson sea of fire, the fire dragon absorbed the surrounding fire-attribute spiritual power.
It grew taller and taller.
Finally, it reached a hundred zhang.
But what reached its peak was bound to decline.
Once the fire dragon reached a hundred zhang, the terrifying fire-attribute power upon it surged outward like a mighty tide with an explosive bang.

"To use the tide power, we have to enter at precisely the right
