Half a month later, ten thousand kilometers to the north of the Hundred Desolation Mountain, in a boundless red desert, a team of demon beasts was rushing at an amazingly high speed.
The demon beasts were all enormous in size. They were more than a hundred meters both in length and in width. The membranes all over their bodies bulged out, with pinky gas filled inside that made them look like balloons that were stitched together.
The gas stored inside the airbags was lighter than air, which made the beasts drift and fly in midair freely.
Such demon beasts were known as 'Land Whales'. Their prototype was the commonly-seen giant sandworms in the deserts of the Blood Demon Sector. The experts of the demon race refined and altered their genes over hundreds of years unceasingly. Finally, they developed airbags that were similar to the swimming bladder and could generate an exceedingly light gas naturally inside the body.
