Chapter 2218: Mysterious Great Formation!

The Snake-man King and others also looked toward the Great Formation.

It was acceptable that this formation could stop their own people.

But unexpectedly, it was even able to block the attacks of the Merfolk King, which somewhat surprised them.

"Again!"

The Merfolk King coldly shouted, and once more swung his huge spear, summoning even more energy to slam into the formation!

The nearly thousand-feet-long huge spear flashed with a dazzling blue light, heavily crashing down!

Boom!

Accompanied by the sound of thunderous roars like rolling thunder!

The entire formation, even the entire main island, shook!

Even several nearby smaller islands trembled!

Waves surged in the sea, creating a spectacular sight!

People on the main island were so frightened that they trembled, and many were shaken so much that they fell to the ground!

However, under the second assault!

Suddenly, the Great Formation flickered with a dazzling golden light!

The next second!

"Roar, roar, roar!"
