Death Tornado.
This was also a Combination Skill of the Death Avatar.
However, it could only be used when there were roughly two to five Bone Dragon- or Ghost Dragon-type Death Avatars.
The Bone Dragon-type Death Avatars would spiral around one another, forming a tornado capable of tearing apart anything and breaking through defenses or Defense Shields ahead of them.
Of course, if the enemy had a body as large as a small mountain, it could also kill them in a single blow.
Gu Xi released two Death Avatar-Bone Dragons at this moment.
Apart from the mandatory Death Dragon Breath installation, these two Death Avatar-Bone Dragons were each fitted with completely different sets: Spark Nightmare Shadow and Extreme Cold Snow Layer.
The one with Spark Nightmare Shadow was slightly ahead, while the one with Extreme Cold Snow Layer was slightly behind.
As soon as the two appeared, they began circling continuously before Gu Xi. They spun faster and faster until they became a spiral formed from a dark-red beam and a bright-blue beam.
This spiral moved remarkably fast.
At first, it had not broken the sound barrier.
But once the Death Tornado was launched, its speed increased further and further. In the blink of an eye, the tornado had already reached sound speed.
At the same time, since both Death Avatars were in Undead Dragon form, their attack range was exceptionally long.
As long as Gu Xi stayed behind the two Death Avatars and had the Wyvern fly at a steady speed.
As the Death Avatars flew faster and faster, Gu Xi noticed something.
The two Death Avatars forming the Death Tornado were absorbing energy scattered through the surrounding heavens and earth.
In other words, if they continued flying like this, the Death Tornado's power would exceed Gu Xi's imagination.
