Chapter 157: Powerful Energy Undulations. The Situation Was Critical

"Not good!"

"This is bad!"

Looking at the huge water ball that was gradually expanding, Yi and the other four Water Elemental Guards' expressions changed. They also knew the power of this water ball. It could definitely kill all of them!

"Don't hesitate anymore! Quickly cast the pentagram formation!" Yi shouted loudly. The current situation didn't allow them to think any longer. The only way to solve this was this!

The other four nodded their heads.

"Pentagram formation, form!" Yi shouted and a strange symbol immediately lit up under their feet.

In the next second, five water balls flew out from the center of the formation and were distributed at five different angles.

"Pentagram formation, activate!"

Following Yi's last shout, these water balls suddenly emitted an intense light and began to spin rapidly.

Waves of water elemental ripples spread out, instantly enveloping the entire space.

"Roar!"
