Two minutes later, a group of hundreds of zergs poured into the cavern at the other end of the bottleneck passage ahead.

Almost without hesitation, the three Zerg rushed into the bottleneck passage.

What is surprising is that it was not the expected tank worm that rushed into the passage, but three sharp knife worms.

Among the three sharp knife insects, two were down-to-earth and charged side by side, and the other actually climbed the cave wall, and the eight long legs firmly grasped the rock wall, and rushed over with their heads and feet.

Barrian's reaction was also extremely fast, and he immediately stopped the attack of the Ranger and the Dark Ranger**, and ordered a group of spellcasters to use a first-level spell point to kill the sharp knife worms of the two heavily armored professionals who had crossed the passage from the top of the cave wall.

Ignorant of the fear of their comrades, the Zerg rushed in one after the other, beyond the reach of the heavily-armored professionals blocking the passage.

Since they could only rush in one by one, they were killed one by one by the casters.

Under Barrian's orders, two warriors with relatively high strength rushed into the passage and dragged out the corpses of the dead knife worms, so as not to block the retreat of the heavy armor professionals who blocked the passage one after another.

Some spellcasters who have cast spells are ordered by Barian to meditate or pray in place to restore their spell slots.

For a third-level mage, it is no longer difficult to enter a meditative state during battle, especially when there are more than twenty powerful warriors around to protect them.

Level 3 mage, build a very familiar level 1 spell, one minute is enough.

In this way, more than a dozen casters take turns casting spells, and the four rangers use the arrows of thorns to block the top passage. Plus a few martial artists and some fighters who are skilled in throwing hunt the fish that slipped through the net, and finally add Barrian's rescue. The three-meter-diameter bottleneck channel was blocked without leakage.

Some spellcasters, under Barrian's deployment, were able to spare time. Restore a portion of the spell slots in turn, although the speed of recovery cannot keep up with the speed of consumption, but this undoubtedly greatly strengthens the caster's most lacking endurance, if this situation continues, before the caster's spell slots are exhausted, it is even enough to destroy more than half of the bugs, if this can be done, the space soldier may not have no hope of victory.

This discovery boosted the morale of the space soldiers.

Just when the morale of the space warriors was at a height, there was a sudden rumbling noise in the cave opposite. Apparently the tank bugs are violently digging into the mountain wall again.

The soldiers who had just been lifted up were suddenly panicked and shaken.

At this time, Bai Qi, who had been outside the team, that is, did not attack or participate in the defense, finally spoke, "Don't worry, the stone wall on the front is more than ten meters thick, even if it is a tank worm, don't think about getting through it for an hour or two." ”

After hearing Bai Qi's words, everyone calmed down again.

Pacified the space soldiers. Bai Qi took out the complex topographic mapper and turned it on, and after a moment, he shook his head in disappointment.

Don't send out tank bugs. Relying on the knife worm alone, it was impossible to shake the two third-level heavy armor professionals who were blocked in the passage, and the sharp knife worm that pounced on the top of the cave. It's just a matter of sending him to death, five minutes later. The two power-type warriors had already pulled out nearly forty corpses of sharp knife insects from the passage, already exhausted and panting.

The offensive of the knife worm is finally not so resolute.

At this time. Bai Qi, who had been squatting at the entrance of the passage and doing nothing, took out something that looked a bit like a mobile phone.

He gently pressed the button on the side of the "phone", and a small capsule-shaped particle ejected from the front of the "phone".

When the capsule particles ejected three meters away from the front end of the mobile phone, the shell cracked in half and bounced out, and a small mechanical mosquito suddenly stretched out.

The mechanical mosquito flapped its wings and quickly mastered its balance.

After the "mobile phone" in Bai Qi's hand popped up the mechanical mosquito, the mobile phone screen suddenly lit up, and a simple operation interface appeared on the screen, as well as the vision of the mosquito.

Bai Qi manipulated the mosquitoes to fly through the passage and came to the cave where the Zerg were entrenched on the opposite side.

At the beginning of the battle, Bai Qi had tried to use the complex terrain mapper to observe the entrenched Zerg in the opposite cave and find the location of the brain worm, but he was soon disappointed to find that the mapper could not scan the figure of the brain worm at all.

The so-called brain worm is the kind of strange insect with spherical shape that Bai Qi found in the daytime battle, and Bai Qi deduced that this new insect should be an existence with extremely strong mental power and extremely high intelligence.

In the past, although Bai Qi knew that the Zerg had a certain amount of wisdom, he was always a little rigid, and he would never have thought of a surprise attack like today, and this time they were ambushed, I am afraid that it was the credit of this brain worm.

Although Bai Qi was disappointed in this point, he didn't think it was too strange, since the stealth mosquito of the Zerg can be invisible to human radar, it is not surprising that this brain worm can be invisible to the mapper, the working principle of the mapper is actually similar to that of radar, it can emit a special electromagnetic wave that can penetrate various media, and then the instrument can accurately analyze the surrounding situation through the reflection of the wave.

Since the complex topographic mapper was ineffective, Bai Qi could only use another high-tech reconnaissance item.

Using some support technology items does not lower the mission and playthrough evaluation.

Bai Qixin took out this thing that looks like a mobile phone, the full name is called "Mechanical Mosquito Detector" There are four miniature mechanical mosquitoes in this box, after ejecting out, the field of vision of the mechanical mosquito can be shared on the screen on the front of the box, and it can also control the flight direction of the mechanical mosquito through the simple control system on the touch screen.

Bai Qi controlled the mechanical mosquito to hover in the cave where the Zerg was entrenched for a while, and soon found three brain worms that were protected by layers of tank worms and sharp knife worms.

Psychic suggestion of the brain worm does not work on the mechanical mosquito.

After finding the exact location of the brain worm, Bai Qi commanded the mechanical mosquito to circle in the air a few times, remembering the distribution of the zerg in the cave opposite.

Perhaps because of the success of Bai Qi's previous decapitation operation, this time, the three brain worms protected themselves extremely tightly, and the three Zerg teams, a total of thirty tank worms, half of them were protected around the brain worms.

The other half of the tank bugs were busy on the walls around the cave.

Instead of banging on the walls of the cave in the direction where the Space Soldier was, the tank bugs were banging on the walls on either side of the cave.

Bai Qi was not surprised by this, the mountain wall facing the space soldier was more than ten meters thick, and it was almost impossible to smash through the hard stone mountain wall behind it, even for tank insects.

Brain worms not only have extremely high intelligence, but also have the ability to scan mental power, and they can easily detect this.

The walls on both sides of the cave are much thinner, the thinnest part is only three meters thick, smash through the cave wall here, and then bypass the two thick walls in front of it, go around the cave where the space soldiers are, look for weak points and smash through the wall to break in. With the intelligence of brain worms that are even more intelligent than ordinary humans, it is easy to make such a judgment. (To be continued......)
