The king of the iron winged bat bug discovered the high-speed defense missile, which sent out a high-frequency sound wave to the high-speed defense missile.

In the channel where it sends out high-frequency sound waves, the interior of two high-speed defense missiles is impacted by high-frequency sound waves. This is just an ordinary type of defense missile, and no special isolation technology is adopted. The two high-speed defense missiles lose their driving force and fall downward.

However, the defense system launched 50 high-speed defense missiles, which of course was launched after judging the strength of the group of "iron winged bat insects".

According to the level of understanding of all Zerg by the interstellar Federation, there is a set of the most strict judgment method of combat power. How to achieve the most reasonable defense is the core of this judgment.

Because the speed of defending the back at high speed is too fast, the king of iron winged bat can't make a second attack at all.

If the king of the iron winged bat moves alone, it can escape at its speed. In the end, it is not deep enough to enter the safe area. With its strong body of level 3 Zerg, it can leave the safe area before it is fatally injured.

As long as they get out of the safe area, high-speed defense missiles will not work.

A defensive missile like this works only within the range of a scanning device.

Only the attack missile can break away from the scanning device and use its built-in scanning device to pursue the enemy.

Twenty second-class "iron winged bats" have also found danger, but they have no time to respond. They can only use iron wings to protect their bodies and protect the population behind them.

The first 20 high-speed defense missiles found 20 second-class "iron winged bat insects". The iron wings that can resist the attack of second-class weapons did not have any effect in front of the terrifying high-speed defense missiles.

After hitting the target, the high-speed defense missile detonates immediately and envelops the target in high temperature.

Twenty second-class "iron winged bat insects" hardly struggle to turn into fireballs. The violent explosion of 20 high-speed defense missiles at the same time also turned the whole area into a sea of fire.

Although the fire affected the line of sight, the scanning device of the defense system was not affected. The subsequent high-speed defense missiles flew into the sea of fire and hit the "iron winged bat insects" one by one.

With more fire rising, David's exoskeleton armor kept coming from behind, and the impact was so severe that he could only use the skills of the master sniper. He used the spirit in his body to form several spiritual channels, transferring the impact behind him to the underground.

Fortunately, his custom exoskeleton armor uses level 3 armor, although he is constantly attacked, it does not hurt his body.

Master Leo also heard the sound coming from David's exoskeleton armor, which could still be heard clearly in the explosion, indicating the violence of the attack.

From this moment on, master Leo really regarded David as a friend. A warrior who can block attacks for his comrades in battle will definitely let any beetle regard him as a close friend.

Master Leo did not say any words of thanks at the moment, and this kind of salvation need not be expressed in words.

When he met a group of iron winged bats, David saved him first. In addition, this time, he owed David too much.

In the sea of fire, the king of "iron winged bat insect" was almost crazy, and its population was completely destroyed in an instant.

It fully withstood the attack of two high-speed defense missiles, leaving many wounds on its body, and even a crack in its proud iron wing.

In the blood lineage of the iron winged bat bug, there is a detailed description of the weapon attack mode of the interstellar Federation. It immediately judges that this is not something it can deal with. When it knows that it can't, it turns around and runs away.

Several high-speed defense missiles chased the king of the iron winged bat bug. The king turned his head to record a high-frequency sound wave, and the number of high-speed defense missiles chasing it was reduced by half.

The king of the "iron winged bat insect" tried his best to shrink his body in the air and wrapped his body with his iron wings.

A high-speed defense missile hit the king of the iron winged bat insect. The fierce explosion and strong destructive force caused several deep visible bone injuries on the king's body.

And the king of the iron winged bat insect also took advantage of this blast wave and flew out like a ball.

At this time, the king's body just flew over a safe area of 200 kilometers. The remaining high-speed defense missiles suddenly lost their targets and then exploded and disintegrated in the air.

"Leo, here you are. I'll go and have a look." When David saw the end of the battle, of course he had to collect the soul of the iron winged bat bug as soon as possible, he told master Leo.

As he turned around, master Leo saw the green glow on top of the custom-made exoskeleton armor behind David's back, which was being covered by an auto recovering coating.

Master Leo can't help but sigh, this is to have a good relationship with master Mckintosh, only then can master Macintosh use grade three materials to make customized exoskeleton armor armor for David.There was no other thought in master Leo's mind. Perhaps it was because he was like this, or because he was in the college all the year round, and he did not have the evil heart of the outside world.

He decided to keep the secret for David. In the end, David revealed the secret to protect him.

"David, wait for me. I'll go and see it too!" He stood up and said as he ran with his feet.

At a distance of 3000 meters, David arrived quickly. The attack effect of high-speed defense missiles is so good that only some ashes of corpses can be seen in this area, even the remains of corpses can not be seen.

No wonder defensive missiles will not be used as a last resort. In this case, there is no way to save useful resources.

The shadow servant absorbed the soul of the iron winged bat insect, but David saw the fleeing King King through the shadow servant's eyes in the air.

There are several huge wounds on the body of the king of the iron winged bat insect. Due to the extensive damage of the iron wing, the speed of the king of the iron winged bat insect was greatly affected, and the flying posture in the air was somewhat skewed.

David knows that the king of the iron winged bat is terrible, but the more terrifying the Zerg is, the more likely he is to have a special sphere of knowledge.

David did not know that this was the king of the iron winged bat. He only knew that it must be very strong and could escape under the attack of high-speed defense missiles.

After making a judgment in his heart, David soared into the air and ran after him in the direction of the king of the iron winged bat insect.

His speed was not fast. He just used his shadow to observe the distant king of the iron winged bat insect from a higher altitude. His body was trying to distance himself from the king as much as possible.

"Leo, help me take back the three second level Zerg corpses that have been thrown outside, and I'll go after the escaped iron winged bat bug!" David didn't forget to ask Master Leo before tracking.

"Be careful. I suspect it's a king of iron winged bat insects. If it is, it's a Zerg close to level 3!" Master Leo watched David's figure fly away, only to remind him finally.

I saw David wave to him, and soon disappeared into sight.

Master Leo shook his head and ran quickly towards the place where he had left three second level Zerg corpses.

Fortunately, perhaps because of the "iron winged bat" group, the bodies of the three second class Zerg have not been found by the rest of the Zerg or the beetles, and are still in place.

Master Leo looked at the bodies of the three second level Zerg, and couldn't help laughing bitterly. It seems that he will lose face today.

He threw all three second level Zerg corpses on his body, which almost completely covered his body. It was really embarrassing to transport the three second level Zerg corpses in this way.

But master Leo was very lucky. He met a group of students shortly after entering the safe area.

They came to check the defense missile attack situation, just met master Leo.

Master Leo used his tutor's identity to issue a task to this group of students, asking them to help transport the three second level Zerg corpses. Of course, the students were very excited.

It's a great pride to be able to work with master Leo, one of the most powerful warriors in the Academy, even if it's transporting Zerg corpses.

A trace of David's mind was in the shadow servant's body. Through the shadow servant's eyes, he saw that the king of the iron winged bat insect did not stop, but moved forward.

The aura of the king of the iron winged bat bug made the Zerg along the way get out of the way.

The king was obviously seriously injured, but he did not stop to rest, but kept flying.

Two and a half hours later, David found himself farther and farther away from the base.

David looks at the possible direction of the king of the iron winged bat on the map displayed by the armor. If the king of the iron winged bat is too far away from the base, whether David will continue to track is a question.

After passing a mountain peak, the king of the iron winged bat flies down, which makes David feel relieved.

Behind the peak is a deep valley, and the king of the "iron winged bat insect" descends to the bottom.

David took out the "camouflage cloth" and put it on his body. He approached the edge of the valley carefully. At this time, his breath and spirit were all restrained. He used the "silent sneak" technique to make his feet even more silent.

In the deep valley, there are gray brown stones on the surface, and the king of "iron winged bat insect" disappears behind one of the very large stones.

"There's a hole in it!" David immediately understood that this might be a nest for the king of the iron winged bat insect.

After checking the map again, the distance between here and the base is 530 kilometers, which is very far.

At least on the map provided by the base, the description of this area is very simple, only the general land type, and there is no other annotation.

This shows that the map information here is drawn by reconnaissance satellites or other aircrafts in the long distance in the air, without field investigation.This makes David have to be more careful, his spirit is highly concentrated, the shadow attendant is also constantly exploring around, even underground.

Strangely, the location here is obviously very suitable for the Zerg to live in, but there is no one of the Zerg. No matter on the ground or underground, the shadow guards have not found anything.

David began to sneak down the valley, saying it was because of the camouflage cloth on his body. As long as he moved slowly, he could have a certain hiding effect. Once David was completely stationary, he could achieve optical invisibility.

In addition, the master sniper's skill of hiding his breath and spirit is almost the same as that of real invisibility.

After more than ten minutes, David finally approached the stone where the king of the iron winged bat disappeared.

The shadow servant first saw the hole behind the stone, which was surrounded by four huge stones, and covered it with stones, so that the hole could be found only through the gap between the stones.

David was very curious about what the group of "iron winged bats" would hide such a hole.

When the shadow servant entered the cave, an ordinary first-class "iron winged bat insect" was hanging upside down on the top of the cave, which should be to protect the cave entrance.

The shadow waiter continued to look inward, and saw a long passage. David, who was sharing the vision with the shadow attendant, was suddenly shocked.

There are some special rocks in the channel. David has seen this kind of rock before, but this kind of ordinary rock is common rock near kryptonite, which has the function of hiding the energy fluctuation of krypton crystal.

It is this kind of rock that prevents the interstellar Federation from using scanning instruments to find kryptonite, which can only be explored manually.

This has also created a professional prospecting profession. The discovery of each kryptonite will bring great wealth to the corresponding forces, and at the same time, the prospectors will get huge rewards.

Generally speaking, the prospector who discovers kryptonite can get a certain proportion of the income of kryptonite. Of course, this can also be seen from the strength of the prospector. More forces will only give the prospector some basic rewards.

David doesn't know if there is kryptonite here, that is, there is kryptonite, and what its scale is. So far, he has only seen the rocks associated with kryptonite.

If you want to keep going inside, you have to get rid of this "iron winged bat insect.".

The iron winged bat bug has the ability of high-frequency sound waves. David is worried that if he attacks, the "iron winged bat insect" can alert his companions in the cave in a way he does not understand before he dies.

David now has two options. One is to go back and report to the college, so that the college can send someone to deal with it.

It's very safe to do so, but David will lose the light sphere of knowledge that the iron winged bat king may have. At the same time, there is no detailed kryptonite data, which will greatly reduce his harvest.

Second, he went into the cave himself and ventured to explore. There were some risks in such an action, especially the king of the iron winged bat insect.

After a moment's hesitation, David made a decision!
