Bang!!

A violent explosion erupted in the middle of the swarm's vanguard, and a giant lizard with a flower-like crown leaped out of the pile of jumping insects that the bombed man was flipping on his back.

The corolla on the head of this weird creature secretes an extremely explosive gas when it is attacked, and the explosion of this gas is so powerful that it can easily knock an Exterminator to the ground.

"Spear hunter!" A mother worm hissed loudly.

Dozens of bloodletting spears flew out of the group of ranged troops behind it, and in an instant, the Corolla Lizard was firmly pinned to the ground.

This lizard is just the most insignificant of the intractable creatures that the swarm encounters after entering the center of the mysterious dunes, and before that, there is a giant stone giant disguised as a green mesa trying to sneak up on the exterminator who passes by in the front row!

If it weren't for the monitoring king insects in the sky that sensed the life signals that were rapidly active in the "mesa" in advance, I am afraid that a whole team of more than fifty exterminators would have disappeared in the sneak attack of the stone giants immediately.

Even so, it took a full ten minutes for the swarm to besiege, consuming hundreds of poisonous blast insects and countless saboteurs' shells before the giant stone man was dismantled into rubble all over the ground with the help of the thunder beast and the fire support of the Air Force Heavy Artillery Governor.

Ever since the Zerg forces entered the heart of the mysterious dunes, their advance has become slower and slower.

The more you go towards the central area, the more strange and powerful creatures there are.

And there was the blood-red gauze mist that had been permeating the swarm, and the ominous mist seemed to be nothing, and it was of no other use than to hinder the careful detection of the Surveillance King Worm, but the two Zerg high-ranking commanders were a little uneasy about it.

Zagara ordered the swarm of toadstools in his team to spray the fungus mist all the way to cover the Zerg troops, trying not to let any Zerg units come into contact with the blood-red mist.

In addition, a stronger and stronger psionic energy fluctuation also came from the central area of the dune, and this psionic energy fluctuation itself was very stable, like the breath of something, all together and extremely regular.

High in the sky, Stokoff's First Fleet of Swarms monitored the central area of the dunes, and through the observation of the King Worms, it judged that the source of the red mist was less than two kilometers in front of the swarm.

But the two-kilometer journey was so difficult, and as the swarm went deeper, the creatures they encountered grew in size.

The stone giants even began to appear in groups, attacking the swarm forces in groups of three or five, and Zagala had to gather most of the thunder beasts to deal with these behemoths that reached fifty or sixty meters tall.

In addition to this stone giant, there is also a giant creature that can be invisible in the veil fog that has been harassing the rear troops of the swarm, these ghost things themselves can be completely invisible, and they also hide their bodies in those veil fog that can shield detection, making the detection of them very dull.

The Shadow Worm troops in the swarm were dispatched by Zagala to deal with these invisible monsters, and from time to time there would be a loud roar and a terrible hiss of the Shadow Worms in the surrounding veil.

After a few hours, the swarm had once again advanced about a kilometer or so, and by this time the intensity of their attack had completely increased to the level of war, and all kinds of strange and bizarre creatures were constantly pouring out of the mist, and their strange abilities brought great obstacles to the swarm.

At the same time, the swarm space in the air also began to be attacked continuously, and a large number of giant flying creatures emerged from the veil fog, and launched a crazy attack in groups towards the interception network formed by the alien dragons.

The heavy artillery governors above the clouds fired non-stop, providing fire support to the swarms on the ground and in the air, and the hive lords also released a large number of hive bugs all the time in an attempt to relieve the pressure on the ground troops.

The swarm troops are like a person who has stepped into a quagmire, and every meter they move forward requires most of their strength.

The ground forces led by Zagala have already suffered tens of thousands of battle losses, not counting the unit consumption generated by the self-detonation of the poisonous blasters.

The state of the Air Force can only be said to be slightly better, thanks to the strong firepower of the Heavy Artillery Governors and the excellent anti-aircraft capabilities of the Corruptors, the losses of the Air Force have just exceeded 10,000.

But the remaining kilometer turned out to be so difficult that Zagala had to have the Mother Worms divide the Swarm forces into separate formations and give individual orders to strengthen the Swarm's ability to advance.

The number of stone giants has increased from dozens to hundreds of swarms at a time, and they stand tenaciously in front of the battlefield like a thick wall, hindering the advance of the swarm.

The battle between the Shadow Worms and the Invisible Behemoths in the Veil of Fog has also reached its peak, and the number of Shadow Worms in the mind of the main nest is rapidly losing out at a rate of dozens per minute.

At the same time, the true colors of those invisible behemoths were finally exposed to the swarm.

It was a behemoth that looked like a chameleon, but had six heads, and was more than 20 meters long and more than 10 meters tall.

The single-molecule blades of the Shadow Worms can inflict lethal damage on these guys, but these giant chameleons can kill a Shadow Worm with every tongue sticking out.

In addition to these two obstacles, there is a long-range monster that can throw plasma balls in the veil, this monster seems to live near the center of the mysterious sand dunes, and the plasma balls they shoot are extremely destructive, smashing on the nanolocust shield of the host of the swarm can splash a large number of ripples every time.

The Zerg Air Force is facing a much more complex obstacle, with the most striking thing being a disgusting creature that looks like a flying slug, in addition to the strange variety of birds.

These soft-bodied flying creatures with winged sheaths are so resistant to blows that even the infected's main cannon requires three full shots to completely wipe them out.

Moreover, the slime on these flying slugs also seems to have strong energy resistance, and the high-temperature plasma of the heavy artillery governor's secondary cannon needs to burn on them for more than ten seconds before it can completely kill them.

These flying slugs attack by spraying an extremely viscous and rapidly solidifying dark green slurry at the target, which, once sprayed on the flying unit, can solidify in a matter of seconds, enveloping the opponent in an amber ball of crystalline fat, causing the opponent to lose the ability to fly and fall to the ground into splinters.

However, fortunately, the large space biological warships of the Zerg have empty slots for the swarm hosts, and the nano locust shields released by the swarm hosts in these empty slots can effectively resist the amber slime of the flying slugs.

However, small creatures such as Allosaurus and Prowler, however, are more troublesome, as they are largely unable to withstand the attacks of the Flying Slugs, so they can only dodge with speed.

In such a difficult situation, the swarm is still stubbornly and slowly moving forward, the huge number base makes the swarm completely not afraid of the life-for-life play, and no matter how many creatures in the mysterious sand dunes are, there is always a limit.

Finally, after a full six hours, the swarm finally broke through the strange creatures and entered the true core of the mysterious sand dunes when it was already completely dark.

As the swarm burst out of the mist, the first thing that caught their eye was a giant black slab about the size of a heavy cannon governor!
