Just when the mutated larvae were still ten meters away from the city wall, holes opened up at the bottom of the city wall, and rows of flames spewed out.
The mutated larvae let out a shrill cry, and kept rolling in the fire.
But at such a short distance, the speed of the mutated larvae is not fast, so naturally there is no way to avoid it.
Once the flame attached to the special combustion accelerant is ignited, it cannot be extinguished, and the body of the mutated larvae and the nearby ground have become a sea of flames.
The mutated larvae that could not get close to the city wall began to explode, but in the flames, the effect of the corrosive liquid in their bodies was greatly reduced. Most of the corrosive liquid was vaporized by the flame before it fell to the ground.
The fire burned for five minutes. After the flames were extinguished, there was not a single corrosion mutant larva at the base of the city wall, only the corroded metal ground remained.
This is still a proper response, and the mutated larvae were not allowed to explode beside the city wall, otherwise these larvae without combat effectiveness would definitely bring huge troubles to the city defense.
David was a little surprised. During this process, none of the first-level Zerg outside the city attacked the city, as if they were waiting for something.
He couldn't help but think of the relevant knowledge mentioned that the Zerg is also an intelligent race, but not all Zerg have wisdom, and the higher the level of the Zerg, the higher the intelligence.
Among the first-level Zerg, it is also possible to alienate intelligent Zerg with a higher degree of intelligence.
He didn't know if this was the case outside the city, or if a more terrifying second-level Zerg had appeared.
Of course, there are city defenses. If the second-level Zerg directly attacks the city defense, it will also pay a huge price. Very few second-level Zerg do this.
Like a heavy laser cannon, if you want to cause damage to the second-level Zerg, you need to continue to attack it.
With the faster speed and stronger defense of the second-level Zerg, it is almost difficult for the heavy laser cannon to lock it.
Only when the second-level Zerg is close to the city defense, multiple heavy laser cannons attack at the same time can achieve the effect.
"Warning, spatial fluctuations are detected, activate the city energy shield!" The city defense system automatically issued a warning.
The shadow waiter in the air saw that inside the city wall, a transparent energy grid covered the entire city, and then the energy grid made a noise of energy flow, and the grid of the energy grid slowly disappeared, forming a completely transparent energy shield .
"This is the legendary energy shield!" David looked at the energy shield that looked like a huge soap bubble in the sun through the eyes of Shadow Waiter, and he was amazed at the technology in this world.
To activate the energy shield to defend a city, the energy required is naturally massive, which requires a lot of krypton crystals, which will be a huge loss for Perrin City.
Therefore, the energy shield will not be activated in normal times, and even in David's memory, he has never seen the energy shield activated in Perrin City.
Now the energy shield has started, which means that great danger is coming.
After the energy shield is opened, it does not include the scope of the city wall, and the city defense system is arranged outside the energy shield.
It is said that except for one specific weapon, most heavy weapons cannot shoot outwards from the inside of the energy shield, which also makes the city defense system completely lose its combat effectiveness once it is protected by the energy shield.
This is the result no one wants to see. If the safety of a city is placed on the energy shield, if the energy of the shield is consumed, the entire city will be completely breached.
Shadow Waiter watched from the sky, trying to find out the source of the danger.
At this time, a famous soldier jumped up from the passage of the city wall. They held various weapons and stood on the city wall in an orderly manner.
The head is covered by a completely sealed helmet. David can't see the expressions of these soldiers, but he can tell that these are soldiers of the army. All the soldiers are wearing the exoskeleton armor of the land lion. Military marine exoskeleton armor.
Even in it, he found five soldiers holding second-grade weapons.
"Attention, the space wormhole will open at any time. Our task is to defend the city wall. Behind us is our home, our relatives, and the soldiers of the Federation will never back down!" Lieutenant Elmer also wore a land giant lion exoskeleton Armor, he said in a low voice through the exoskeleton armor's loudspeaker.
This is not only for the soldiers, but also for other soldiers on the defensive wall.
David saw the military rank on the land lion exoskeleton armor, the rank of lieutenant plus wearing the military land giant lion exoskeleton armor, he immediately knew who it was.
This is Daly's father, and he is also the captain of the Soldier Squadron of the City Defense Brigade.
He counted again, and the hundred or so military soldiers here happened to be the entire squadron.
It seems that the Perrin City Defense Brigade sent out the entire military squadron.
It's just that David didn't know what the space wormhole Lieutenant Elmer was talking about was. Shadow waiter looked around and didn't see any Zergs appearing.
Just when he was observing through Shadow Waiter's field of vision, he suddenly felt a strong strange energy fluctuation, which was Shadow Waiter's innate perception, and its position was five meters above the city wall, which was a thousand meters away from No. 5 control room.
Shadow Waiter looked in that direction, and the military apparently discovered the specific location of the space wormhole through some device. The two nearest heavy laser cannons turned their huge cannons and aimed at that location.
Then two dazzling light beams were sent out, piercing through the air, passing through the position of the strange energy fluctuations.
But a brighter light came on, but fortunately, Shadow Waiter didn't have all kinds of glaring feelings towards the light, no matter how bright the light was, it didn't affect it.
At this moment, the two laser beams seemed to have lost their light. In Shadow Waiter's field of vision, the surroundings became pitch black due to the appearance of space wormholes.
This is actually just an illusion, because the space wormhole is too bright when it appears.
The space wormhole only lit up for less than a second, then stabilized, and the strong light disappeared, and a water-ripple-like hole appeared in the air, and the surroundings of the hole emitted blue light.
The two lasers continued to attack, but did not affect the appearance of the space wormhole.
As soon as the space wormhole stabilized, Shadow Waiter, who was far away, heard a huge buzzing sound, and then flew out of the space wormhole with a pair of transparent wings, an ugly head and knife-like forelimbs. Flying Zerg.
"It's tearing flying insects, pay attention to formation!" Lieutenant Elmer ordered loudly.
The tearing flying insect is a first-level flying Zerg that acts in groups. Although it is not the most powerful existence among the first-level Zerg, its speed is the fastest.
Coupled with its flying ability, the tearing insect has become the most difficult first-level Zerg to deal with.
The first tearing insect was hit by two laser beams as soon as it flew out of the space wormhole. The powerful insect shell could not resist the continuous attack of heavy laser cannons. The consequences of this frontal hit made this tearing insect The wings on the back of the flying insects were vaporized, and the shells on their bodies also turned scorched black.
But its tenacious vitality made it instinctively want to highlight the range of the laser beam. Just when the tearing insect successfully highlighted the attack of two laser beams, a second-level battle ax with a faint blue light came from the tearing flying insect. Chop off the worm's body, splitting it in two.
It was Lieutenant Elmer who made the shot. Just now, he kicked his feet hard on the ground, tearing apart the flying insects and just as soon as he escaped from the laser beam, the second-grade heavy ax in his hand completed the fatal blow with the momentum.
"Good!" All the soldiers cheered loudly.
The first-level Zerg is not so easy to deal with. Even if they are well-trained, they need the cooperation of five soldiers to kill the first-level Zerg without injury.
Of course, the reason why the tearing insect was fatally hit by Lieutenant Elmer, the soldiers all knew that it was due to the heavy damage from two laser beams, but it was right to be able to kill a first-level Zerg from the very beginning. Great boost in morale.
Contrary to the excitement of the soldiers, Lieutenant Elmer was not at all happy. This time, some Zerg in space chose Perrin City, which was the worst result.
He didn't know how many Zergs would appear next. Although he scanned the space wormhole, he didn't know whether he could block the Zergs' invasion by relying on his hundred soldiers.
As for those civilian soldiers, he didn't expect that unless they were soldiers who had retired from the army and returned home, their real combat effectiveness against the Zerg was far inferior to that of army soldiers.
