Xue Hua stood at the exit of the passage and looked at the sandworm queen in a daze, but the insect swarm would not follow him in a daze.

The order to attack has been given, and seeing that this guy is so big, he must be very resistant to beating, so the insect mother is relieved to boldly let the insect swarm let go of her hands and feet to fight to death.

However, just as the swarm was about to rush forward, the sandworm queen lying on the ground suddenly raised her body and let out a silent roar, and the sound waves formed a sound wave that swept in all directions, slamming into the black stone walls around the room.

Some of the obelisk-shaped stone bricks in the stone walls cracked, revealing clumps of disgusting pink biological tissue.

The surface of the biological tissue fluctuated very rapidly, and then several exits to the outer oasis appeared on the surface of the tissue.

Immediately afterward, countless insect monsters such as death beetles, eagers, and sandworms frantically poured in from those exits, and Xue Hua even saw a flash of dark gold color in them.

"This is the creature's last means of defense, those exposed biological tissues should be part of the creature's brain, most of its brain tissue is underground, but the body of the aboveground part is strangely the main nerve center, its brain tissue is very huge, has wrapped the entire area, these black stone bricks should be some kind of growth inhibition device, to ensure that it will not be crushed alive by its own brain tissue......"

Abbather sat on the back of the cockroach, walked up to Xue Hua, and explained to him in a slow voice.

Crushed to death by his own brain tissue......

What is this... What a humiliating death!

Xue Hua often saw such a sentence on the Internet in his previous life, called "The brain is a good thing, but it's a pity that you don't have it." ”

However, for this sandworm queen, the "brain" seems to be too much~

It can be seen that there are too many brains, and it is not necessarily a good thing, we must learn to look at problems with dialectical thinking......

Ahem... It's far away~

However, since this thing can use sonic means to control the monsters in the oasis, Xue Hua is very curious, why didn't it use this ability to stop them from advancing before?

He looked at Abbathhar suspiciously, and asked the question in the mind of the main nest.

"The creature is too large to move due to its brain roots, so it should only be used to defend against intruders who have already reached its original location.

There is a price to be paid for using this method, and the price is to destroy those growth inhibition facilities.

If these growth inhibition devices are destroyed, the creature will be overwhelmed by its growing brain tissue for the rest of the day, so this defense can only be used as a last resort. ”

Abbather quickly answered Xue Hua's question in the mind of the main nest.

"I see, which means that even if we don't do anything and walk away now, this thing will kill itself?"

Xue Hua nodded and asked.

"Once the creature activates its last defenses, it shuts down all nerve node pathways, leaving the intruder with no way back but to be killed by the influx of enemies and buried with it in this unknown subterranean facility."

Abbathhar explained in an emotionless voice.

"Hold the grass! Is it a self-detonating device? Xue Hua was startled and hurriedly turned around, only to find that the door of the passage that had been opened by Abbather when they came had indeed been re-sealed.

However, Xue Hua didn't panic much, because the consequences that Abbather said were only for those unlucky people who inadvertently broke into here, but for the swarm, no matter how many monsters poured in, it was just a dish.

After all, with his continuous support behind him, I really don't know how to lose this battle.

As more and more monsters poured into this small space, the swarm finally began to engage in a head-to-head battle with the swarm.

The stinging snakes were the first to launch the first round of attacks, and the destructive explosive spines rained down on the front row of the monster group, and the fastest moving death beetles and water and fertilizer warriors were suddenly attacked, although the explosive spines of the stingers were not very penetrating, but they were not something that the thin shells on their bodies could resist.

So, after a burst of "sparks with lightning", a big hole suddenly opened up in front of the surging monster group.

And at this moment, the piercing roar of the alien dragons also sounded in the sky above the combat area, due to the high altitude of this area, Xue Hua had just released hundreds of alien dragons to support the battlefield, but their main opponent now was a cluster of eagers who could also fly in the air.

This time, among the monsters summoned by the Mother of Sandworms, the number of Desirers was the largest, and a large group of black and green people poured out of the exits opened in those brain tissues, and soon filled the entire battlefield airspace.

Allosaurus works well against these little bugs, and the blade worms they spit out can kill all the bugs in a line as they fly.

But the number of eagers was too much, and Xue Hua had no choice but to continue to send a group of alien dragons, and then turned some of the attack targets of the stinging snakes to the air, which barely suppressed the ferocious arrogance of the eagers.

On the ground battlefield, because the scope of the battlefield was too narrow, the swarm forces could not be used, and Xue Hua did not dare to let Isha use "orbital bombardment" to clear the area, for fear that one would accidentally blow up the fat mother of the sandworm to death.

Therefore, the swarm can only adopt defensive advance tactics for the time being, and slowly move closer to the direction where the mother of sandworms is located.

As for the Thunder Beast, the ultimate weapon of the Zerg Land Battle, Xue Hua did not release them, the reason was that the space was too small, the body length of a Thunder Beast was tens of meters, and Xue Hua made a slight visual inspection, the length of the entire battlefield was only tens of meters, even if the Thunder Beast was released, this space would greatly affect their strength.

However, in the advancing tactics of the swarm, a kind of Zerg unit that Xue Hua had rarely noticed before exerted extremely strong destructive power.

This unit is the mutant of the Stinging Serpent, the Lurker.

These bugs, which dive underground to attack, are generally used as defenses, as they do not move underground like cockroaches.

Due to problems with the structure of the body, they cannot do it even with forced displacement underground.

In terms of the battles that Xue Hua's swarm has experienced, since their appearance, there has been no defensive battle that can allow them to show their advantages, so Xue Hua is also a little ignorant of this kind of Zerg class that was originally called "ground thorn" in the game.

However, the battle that is going on now has made Xue Hua see their value.

These creatures with six curved, sharp digging legs can easily dig through the seemingly hard black stone floors, then burrow into the ground, using rows of high-density telescopic spikes to kill the monsters that rush at the swarm.

The fragile defenses of the monsters could not stop the lurkers from attacking from the ground, and every time a group of lurkers attacked, a square area in the mob group would be splashed with green blood in a very neat manner.

The Lurkers follow in the footsteps of the swarm in a cycle of stealth-kill-emerger-move-dive, and their lethality leaves even the front-row melee units of the swarm with nothing to do.

Seeing that the lurkers were so violent, Xue Hua was not conservative, and he ordered the worm mother to expand the defense circle of the insect swarm and accelerate the speed so that he had space to deploy saboteurs behind the battlefield.

The insect mother took the order, and the defensive front of the insect swarm suddenly expanded outward, and under the cover of the lurkers and stinging snakes, the action monsters of the insect swarm were powerless to stop it.

However, just as the insect swarm began to approach the vicinity of the Mother of Sand Worms, the top exterminators were suddenly dyed with a green veil, and at the same time, Xue Hua saw in the mind of the main nest that the life indicators of the more than ten exterminators who had suddenly become green were rapidly declining, and soon dropped to a very dangerous level.

Xue Hua immediately realized what this was, so he hurriedly told the exterminators to retreat backwards, and asked the mother worm to come forward for treatment.

At the same time, he was also very shocked in his heart.

He knew that the mother of sandworms had a toxin aura, but he didn't expect that this guy's toxin would have such a powerful effect on the swarm?

You must know that the Zerg units already carry various deadly viruses in their bodies, and even some units, such as the Corrupted, are simply developed from cancerous cells.

What kind of toxins can such organisms do to help them?

Just when Xue Hua was very surprised, Abbather once again answered his question in the mind of the main nest.
