On the third night after the "stone skin worm" nest was bombed, a pair of hate eyes were watching outside the base of SRA combat Academy.

If we say that all the actions of the former "stone skin worm" kings are for the sake of the ethnic group, in order to get a more perfect evolutionary possibility, we must obtain "pregnant crystal stone".

Now the only idea of the stone skin worm king is to kill. This is the nature of the Zerg, especially when there is only hatred in their hearts.

The choice of the king of "stone skin worm" is very simple. The base of SRA combat academy has not been built well. The infrastructure project is too large. Although there is a very professional team in construction, it will take some time to complete.

Before that, the entire SRA combat academy base had only basic level scanning and defense capabilities.

So the stone skin worm King chose this place to carry out its first revenge. The dark night gave the Zerg the best cover. Without a large scanning device, the temporary defense system was much less effective.

The king of the stone skin worm disappeared to the ground. In the past three days, it built an underground passage of five meters in width and height.

Even for the king of the stone skin worm, this project is not easy. For three days, it has been consuming mutation energy, then resting and recovering, and then consuming and recovering.

It is hatred that supports the king of the stone skin worm. It has built a wide passage from a hidden place 20 kilometers away from the base of SRA combat academy to the base near the Academy.

The reason why the channel was not directly dug into kryptonite is that the first project of SRA combat academy is to bring the whole kryptonite mine into a professional safety system.

This safety system is specially designed for kryptonite. It is a special safety system developed by the federal government to protect kryptonite. With the energy support of kryptonite, it can resist the invasion of kryptonite from underground and send out an alarm at the same time.

The king of "stone skin worm" has inherited memory, and higher wisdom has made it understand the habits of the Federation.

"When the college base is established, we will be able to kill Zerg every day to exchange for points, just like the students of alidia first college, cardor college and volgo college, and have a continuous source of cultivation resources!" A student wearing exoskeleton armor at the battle Academy of SRA said with vision to his companions.

The treatment of SRA combat academy is good. Grade I fortified meat is almost a large supply, and grade II fortified meat can also be applied to the academy when necessary.

But this kind of treatment is relative. Compared with the ordinary colleges, the SRA combat academy, which has been invested with massive resources in the SRA star region, is naturally excellent, but it is much different from the colleges that have the real base of the Academy.

For example, the students of the first college of alidiya can exchange the three-level fortified meat at any time as long as they have the points, not to mention the secondary fortified meat. This is the advantage of having the college base.

So the students of SRA combat college are very envious of the students of these colleges, and now they are about to have their own academy base, which makes them very excited.

Especially in recent years, the college often organized them to clean up the nearby Zerg, and the students had a good harvest, which made the students have strong expectations for the base.

"It's said that those colleges can exchange for a third level fortified meat as long as 100 points, which is produced by Level 3 Zerg, which is extraordinary and can be killed. When can I use level 3 fortified meat?" His companion also said with emotion.

Two of their student beetles are in charge of guarding the base. Although they have temporary scanning devices, the tradition of SRA combat academy requires students to take turns to guard the base.

Two student beetles stand on the defense wall, which is 20 meters high and is made of alloy. This is the first defense line of the base that has not yet been built.

They are responsible for the guard of the 100 meter defense wall. As long as they stand on the defense wall, the light outside the defense wall will light up the area of several kilometers outside into daylight, and any Zerg approaching will be found.

Because it is a base that has not yet been fully constructed, the defense system of the base is some defensive missiles, but because there is no special large scanning device for the base, the attack distance of the defense missile is only 10 kilometers.

This is the defense system of the second level Zerg, and the first level Zerg is inspired by the extraordinary guard of the base, so that the first level Zerg can't get close to it.

Of course, this is also a temporary measure. After the base is completed, it will be replaced by a more reasonable and perfect defense system.

The task of the two students is to find some special Zerg. Because of the incomplete scanning device, some Zerg with special ability may avoid scanning.

This requires the students on duty to be able to find out and make judgment, can destroy themselves, or call on the standby combat Beetle team.

When two student beetles were dreaming about the future, two white lights flashed across the ground in the distance, then appeared beside the two student beetles, and then their bodies shook.

Two student beetles look at each other's chest claws, which belong to Zerg weapons.They wanted to sound an alarm, but another claw had penetrated their unsealed armor.

Two student beetles fall to the ground, revealing two "Leaping flash insects" behind them. Although they are first-class Zerg, they have extremely strong jumping ability and good attack power. They have absolute advantages in raiding fixed targets at night.

After killing two student beetles, the two "jumping flash insects" jump again. Their targets are several high defensive missile launchers.

After the two "Leaping lightning insects", a large number of "jumping lightning insects" appeared. Their targets are also the defense missile launchers and various defense facilities of the SRA combat Academy.

The temporary scanning device at the base of SRA combat academy does not have the ability to scan inside, only 10 kilometers outside the base. Therefore, the "Leaping lightning worm" that intruded into the base was not detected by the scanning device and did not give an alarm.

This is the disadvantage of not having built a base, which could have been made up by the on duty beetles, but who would have thought that the on duty beetles would be killed in an instant and would have no time to send out the alarm signal.

"Boom It was an explosion after the missile launcher was destroyed.

After this explosion, it is a continuous explosion.

Although the defense missile is very powerful, its body is extremely fragile. Ordinary alloy and energy thrust engine will explode as long as it is broken.

The first explosion made the base awake. Draper, who was in the temporary office, ran out of the building for the first time. He saw the flickering "flickering insects" in the night.

"Zerg attack, all people immediately respond to the enemy with armor!" Draiper's extraordinary force called out as he loaded his body with green light "extraordinary armor.".

His voice penetrated through the building and reached everyone's ears.

Although SRA combat academy has little experience in fighting with Zerg, there are not many battles. Although it is a temporary gathering at night, they all rush out of the dormitory very quickly.

It also has something to do with the fact that this is the guardian star. Every student will put his or her exoskeleton armored container beside him. The danger of the guardian star and the requirements of the college make them do so.

So when the base's few defense facilities were destroyed, the student beetles formed a battle array, ready to attack the "jumping flash bug.".

Draiper's extraordinary speed is very fast. In order to speed, he only used the third level sword, and killed three "jumping flash insects" in a short time.

They did not choose to fight. After completing the task of destroying the defense facilities, they immediately jumped out of the defense wall and left in the distance.

Even with draiper's extraordinary speed, it would be a bit of trouble to hunt down the "jumping flash bug". In addition, the sudden emergence of Zerg made him dare not leave the base to pursue and kill.

"Don't worry about the" jumping flash insects ". Immediately guard the defense wall and guard against the attack of Zerg!" Draiper stopped the student beetle's pursuit in a loud voice and ordered.

At this time, both Anne Lin and Klaus were coming. They were standing beside Draper in "extraordinary armor".

Dozens of holes appeared on the ground in front of the defense wall that had just been attacked, and countless "corrosion mutant larvae" rushed out.

"Corrosion mutant larvae" have no strong jumping ability, so they can't rush to the defense wall. They hit the defense wall heavily with their bodies. In an instant, their bodies burst open, and the corrosive liquid flows on the defense wall, making bursts of hissing sound.

A series of eroded holes appeared on the defense wall, and the "corrosion mutant larvae" in the back continued to make the holes enlarged enough for the "corrosion mutant larvae" behind to rush through.

"Damn it, it's another move. We have to send out a call for help. The king of the stone skin worm is coming!" Exclaimed Claus, with an extraordinary, gloomy face.

In the previous "King hunting" campaign, he was the only one who participated in the battle of the stone skin worm king. He had seen the attack method of "corroding mutant larvae".

Because of this familiarity, and because of the Zerg's overintelligence, Klaus understood that this was an attack directed by the king of the stone skin worm.

Klaus knew very well how terrible the king of "stone skin worm" was. He knew that even if he joined hands with two extraordinary people around him, it would be difficult to defeat him.

In particular, the base's defense weapons were destroyed, so that the base's weapons to deal with the "stone skin worm" King were useless.

At this time, the students of SRA combat academy showed their excellent fighting quality and immediately changed their formation to defensive and counterattack formation in the face of "corrosive mutation larvae".

The big shield beetle is in front of the beetle to block the "corrosion mutant larvae", while the spear beetle at the back is responsible for cleaning up the protruding "corrosion mutant larvae".

The "corrosive mutant larvae" are not strong, or very weak. The only weapon of this weak class of Zerg is to use the corrosive liquid in the body to hurt the enemy.

However, this kind of corrosive liquid is ineffective for grade materials, which makes it not a threat to the class A.As long as it is not directly drenched on the body by the corrosive liquid of "corrosive mutant larvae", there will be no danger.

The three extraordinary men did not participate in the battle. They were suspended in the air, staring at the war, looking for the traces of the king of the stone skin worm.

The king of "stone skin worm" is their opponent. If the king of "stone skin worm" fights with the students, it will be a unilateral massacre.

As more and more students participated in the battle, the scene stabilized.

Some students took the disinfectant water that had been prepared for a long time from the warehouse and sprayed the corrosive liquid on the ground with spraying device.

In the last "King hunt" campaign, the king of the stone skin worm used the corrosive liquid of the "corrosive mutant larvae" to burn, killing two extraordinary people and injuring several extraordinary people. This tactic had no effect.

On the second day after that battle, a large amount of disinfectant water for the corrosive fluid of "corrosion variant larvae" was stored in the warehouses of various college bases.

Just as the Zerg understand the federal humans through inheritance, the federal humans also know the Zerg very well. All kinds of Zerg means have corresponding response measures.

It's just that there are too many Zerg attacks to prepare for every response, but it can also ensure that the Zerg's methods can only have one effect.

Just like now, with the spray of disinfectant water, the corrosive liquid on the ground will melt into ordinary water as soon as snow meets fire.

In the cave in front of the defense wall, another swarm of Zerg came out. This time, it was no longer "corrupting mutant larvae", but "exploding poison and attacking beetles.".

It is a kind of one-time consumption of beetles.

"Everyone switch the internal circulation system, turn on the spray system!" A tutor has appeared to direct the students.

One by one, the "poison blast beetle" hit the big shield beetle's shield, and then exploded, turning into a poisonous fog.

It's just that the spar combat academy has been prepared for a long time. The spray system is the cleaning system for the exterior wall of the base. Because the water of the guardian star is very precious, this spray system is specially prepared for special situations like this.

At this time, of course, SRA combat academy would not be stingy with water. The spray system was originally prepared for the petrochemical gas of the king of the stone skin worm. Although we don't know whether it is useful, it can prevent the petrochemical gas from combining with other smog and cannot be distinguished.

The poison of "exploding poison attacking the beetle" didn't work. As soon as the poison mist rose, it was washed away by the spray of water mist.

The student beetles are not completely without casualties. Some weaker big shield beetles, after being exposed to the explosion of the "explosive poison impact beetle" for many times, will be knocked down by the "explosive poison impact beetle" as long as they are unable to hold the big shield and lose their defensive position.

When a big shield beetle is injured or dead, a big shield beetle will arrive quickly. The student beetle has no time to grieve. The only thing they have to do is to kill the Zerg in front of them.
