Chapter 587: A Strike

"I don't know but I suggest being cautious." Yun Wanli chose his words carefully. He opened up two extra swirls and two more beast kings came out. Both beast kings had bloodlines of the Ocean State and were currently at their prime.

One of the two beast kings was Cracking Rock Dragon, a rare kind. Such a dragon subspecies lived underground where thick layers of rocks gathered; being quite strong in defense was a distinctive trait.

The other one was a Winged Wind Listener. It was about six to seven meters long and looked like an insect, with sharp claws at the end of each limb. Even though small-sized, it possessed great energy and was able to move with agility.

It was said that a Winged Wing Listener could reach a speed that was twenty times the speed of sound; it could travel faster than the best fighter plane of the time.

Another trait was its listening ability, being able to pick up noises a hundred thousand meters away.
