"Retreat!" the immortal army general yelled frantically at the top of his lungs from afar. Only someone out of their mind would stay behind to fight for their life against this dense colony of sand crystal thunder ants that stretched as far as the eye could see. Even though sand crystal thunder ants possessed greater strength than ordinary sand thunder ants and slightly higher intelligence, this intelligence was, in reality, extremely limited. There was absolutely no need to stay behind and fight these sand crystal thunder ants to the death. Not to mention that if this immortal army stayed behind to fight this boundless swarm of sand crystal thunder ants, death was virtually certain.
Even if they could fight off these ant colonies, what possible meaning would it hold for them if a portion of the immortal army survived at the cost of heavy casualties? It would serve no purpose whatsoever.
Yet even though the lead immortal army general wanted to retreat, he despairingly discovered that the retreat route behind them had also been flooded by a massive surge of ant colonies. Or rather, these ant colonies had originally been a single gargantuan swarm; but once their numbers reached a certain scale, they behaved just like a tidal wave. Some currents were blocked by mountain ranges and temporarily stalled, while currents in other places pressed forward on smooth terrain, naturally and without any human guidance flowing around to the rear of the mountains.
What this immortal army faced at the moment was roughly this very situation.
The ocean-like swarm of sand crystal thunder ants swept without any fanfare across the surroundings of the immortal army before them. Tens of thousands of Mingluo immortal soldiers formed a battle formation, and the defensive barrier they projected kept the ant colonies at bay.
