"Let's go in!"
The Thunder Clan's Clan Chief shouted and led everyone toward the huge lightning vortex.
Almost at the same time, the people from the Lightning Zerg race, the Lightning race, the Black Thunder Clan, and the other three races also flew towards the huge lightning vortex.

In front of them was an endless lightning.

When they reacted, they realized that they had already appeared on an ancient ruin.
In the sky above the ruins, there were dark clouds that were as black as mountains.
Almost at the same time, they saw three other groups of people.
