Slashing The Stronghold, Worn-out Planet Zi

With Planet Zi in the center, countless defense lines were built across a 7 lightyears radius. Among them, there were eighteen strongholds that stood out and were known across the galaxy.

In order to attack Planet Zi, one must first go through all eighteen of the strongholds.

Ancient Frost Strong Hold, which was the first in the line of eighteen, and its owner was a Grand Daoist Celestial. He stood on the walls of the stronghold and gazed upon the armada of bandits with a disdainful look.

"Ignorant fools trying to attack Planet Zi? They are ahead of themselves. There are eighteen defense lines across 7 lightyears and you scoundrels won't even make it through the first one!" the owner of Ancient Frost Stronghold, Ancient Frost Daoist Celestial, said.

Planet Zi devoted a lot of effort and resources to building the eighteen strongholds. Each of them was equipped with countless formation seals that made them indestructible.
