David recruited Shadow Master, who took out the third-level heavy axe from the space item and held it in his hand.

This was his worst plan, just in case of mistakes, and he quickly killed the "Iron Winged Batworm" guarding the goal after making a mistake.

David led out the "Sleeping Pattern" from the wall of the Soul Fortress. The "Sleeping Pattern" was not fast and slowly flew into the cave entrance.

At the same time, the Shadow Assistant also flew into the cave entrance. David relied on the Shadow Assistant's eyes to control the "Sleeping Pattern" and flew towards the "Iron Winged Batworm".

Obviously, this "Iron-winged Batworm" did not expect anyone to plot against it. It has always maintained a sound wave conduction around it. In the range of the sound wave, any creature will appear, it will be discovered.

So don’t look at the ‘Iron Winged Batworm’, but in fact it knows everything around it.

This is a talented ability, in a dark environment, using sound waves instead of eyes.

However, this kind of talent ability can only be effective on entities. Whether it is the "Sleeping Pattern" or the Shadow Master, this kind of talent ability cannot be discovered.

The "Sleeping Pattern" flew into the body of the "Iron-winged Batworm". It was obvious that this first-level "Iron-winged Batworm" did not have too strong soul strength, and even the "Sleeping Pattern" could not be discovered, let alone resisting the "Sleeping Pattern".

After a minute, the "Iron Winged Batworm" opened its iron wings and opened its eyes to look around. David walked directly into the entrance of the cave, and the "Iron Winged Batworm" seemed to have not seen David.

At this time, a strange connection was created between the "Iron-winged Batworm" and David. The "sleeping pattern" in the soul of the "Iron-winged Batworm" had long been transformed into the "bewitching pattern" after this minute. This "Iron-winged Batworm" became David's puppet.

David did not bring this 'Iron Winged Batworm', but left it here.

David walked twenty meters along the passageway facing the hole, and no "iron-winged batworm" appeared at this distance.

After twenty meters, the space suddenly became clear, and a space of about thousands of cubic meters appeared.

This is a huge cave. It was originally supposed to be dark and dull, but some light spots on the cave walls made the cave clear.

The shadow servant flew to a light spot, but saw the true body of the light spot, which was a Krypton crystal source ore, with very good quality.

The light spots here are krypton crystal source ores, which provide light for this space.

There are dozens of cave entrances on the walls of the cave. There are no "iron-winged batworms" in the cave, but you can see some traces of life left by "iron-winged batworms".

The bottom of the cave is full of various bones, some excrement, etc. If David had not had an air filtration system with customized exoskeleton armor, he would have probably been fumigated by the smell in the cave.

David looked at dozens of holes and his face looked a little ugly. He had been delaying a lot of time before, giving the "Iron-winged Batworm" a little breathing time. If he searched the holes one by one, it is very likely that when he found the "Iron-winged Batworm" king, the "Iron-winged Batworm" king would have recovered most of his injuries.

At that time, it will be hard to say whether he will kill the king of "Iron Winged Batworm" or the king of "Iron Winged Batworm" to kill him.

Just when David was anxious, Xiaobai, who was in the customized exoskeleton armor, suddenly twisted his body.

David's spirit is connected. You should know that Xiaobai is very quiet on weekdays and usually does not disturb David. When he moves now, he should have discovered something.

Sure enough, Xiaobai warned David, and there was a breath that made it extremely afraid of him nearby.

"Xiaobai, do you know the direction of this breath?" David tried to ask through his spirit.

Xiaobai immediately passed on a direction to David, and there was a hole in that direction.

David soothes Xiaobai with his spirit, then rises into the air and flies towards the hole.

Of course, the Shadow Master flew over one step earlier and discovered any possible dangers for David in advance before being forty meters away from him.

When he flew to this cave, David immediately sensed the strong energy aura of Krypton crystal. With the restrained nature of Krypton crystal energy, being able to have such a strong energy aura can only show that the number of Krypton crystals here has reached a very terrifying level.

When Shadow Master entered the entrance of the cave, he saw that the walls of the cave were filled with dense krypton crystal source mines, which were countless times denser than the big hole outside.

No wonder there is such a strong energy aura of Krypton crystal. There are so many Krypton crystal source ore, which also gives David confidence that this is the cave of the king of the "Iron Winged Batworm".

The Shadow Master looked inward and didn't have to look for it anymore. Just two hundred meters inside, the "Iron Winged Batworm" king was stuffing a piece of Krypton crystal source mine into the import.

At this time, the "Iron Winged Batworm" king had much better injuries than before, especially the damage on the pair of iron wings was gone.

As a flying Zerg, the king of ‘Iron Winged Batworm’ instinctively takes healing over the most important iron wings to it, so it can repair the iron wings as fast as possible.

If David hadn't seen the extremely deep wounds on the King of Iron Winged Batworm', he would have turned around and left now.

No matter how much wealth you have or how tempting the knowledge of the "Iron Winged Batworm" king, it is far less important than your own life.

After taking a piece of Krypton Crystal Source Order, the king of ‘Iron Winged Bat Worm’ seemed not satisfied yet, so he picked up a piece of Krypton Crystal Source Order and swallowed it again. Only then did he hang his body upside down, and relaxed his whole body and began to digest Krypton Crystal Source Order to speed up the healing of his injuries.

This group of "iron-winged bat insects" have not been here for a long time. If it had been a long time, they would have been discovered by the college base long ago. How could the college base allow such a dangerous Zerg group to settle down here?

That's why this Krypton crystal ore has not been mined much.

Although the Zerg's devouring ability is extremely powerful, only a small number of particularly powerful "Iron Winged Batworms" can swallow the Krypton crystal source ore.

The other "iron-winged batworms" still need to be passively absorbed in the Krypton crystal energy environment to grow slowly.

The king of the "Iron-winged Batworm" returned here as soon as possible after the tribe was destroyed. The reason was that there was hope for the tribe here. A group of insect eggs with the gene inheritance of the "Iron-winged Batworm" are here, waiting to hatch at any time.

The king of ‘Iron Winged Bat Worm’ needs to return here to protect these insect eggs. Without its protection, the rest of the Zerg will be targeted at any time.

The distance from the entrance of the cave to the king of "Iron Winged Batworm" is 200 meters. To be honest, this is not a particularly good sniper distance.

The distance is wide and there is no sniping position, so it is impossible to snipe at all, so if David wants to snipe, he can only be at the entrance of this cave.

Fortunately, the "Iron Winged Batworm" king's body was hanging upside down and motionless, which was a static target for David.

Only two hundred meters away, David was wearing a "camouflage cloth" and carefully descended to the entrance of the hole, then lay on the ground. He placed the third-level heavy axe aside and removed the customized super-caliber sniper rifle behind him.

David knew that he had only one chance, and at a distance of two hundred meters, the "Iron Winged Batworm" king would never give him a second chance.

Gently pressing the third-level sniper bullet, David looked at the king of "Iron Winged Batworm" through the sniper lens.

Although the "Iron-winged Batworm" king's body was wrapped in its iron wings and his body was not visible, David had long recorded the wounds on the "Iron-winged Batworm" king's body.

At this time, in David's observation, he could directly judge the wound behind the iron wing of the "Iron Winged Batworm" King through comparison, and find the best sniper position.

Originally, sniping the head was the best choice, but David was worried that this "Iron Winged Batworm" was already a third-level Zerg. In this way, under the multiple protection of its skin and bones and iron wings, and this distance was not the best sniping distance. Even if you use a third-level sniper bullet, David was not confident that he could penetrate so many defenses and destroy his head.

In David's mind, a straight line was drawn from the sniper position to the heart of the king of the "Iron Winged Batworm". On this straight line, there was only one layer of protection for the iron wings. The skin there had been long damaged and avoided the bones.

This time, David did not even block the sound of the customized super-caliber sniper rifle. He thought of the particularly eye-catching ears of the king of "Iron Winged Batworm". The position of his sniping and the position of the king of "Iron Winged Batworm" is two hundred meters away, but there is almost a straight passage in the middle, which is very convenient for sound transmission.

There was a loud "boom", but the faster than the sound was the third-grade sniper bullet fired. The speed of the third-grade sniper bullet was much faster than the sound.

The sniper bullet jumped over a distance of 200 meters from the moment it left the sniper barrel and appeared outside the iron wings of the king of "Iron Winged Batworm".

The king of the "Iron Winged Batworm" actually maintained sound wave conduction, but it was injured, so the sound wave conduction was controlled within a range of 100 meters.

This is also the reason for having confidence in the safety of this nest. There are "Iron Winged Batworm" guards outside. If there is an enemy, it will make a special sound and it will be received immediately.

When the third-level sniper bullet entered one hundred meters, the "Iron Winged Batworm" king woke up. Before it could move its body, the third-level sniper bullet hit its iron wings.

The iron wings could not defend themselves. After the third-level sniper bullet was consumed, it shot a small hole in the iron wings and continued to shoot towards the body of the king of "Iron Wings Batworm".

As David expected, the third-level sniper bullet shot into muscles without skin protection, passed between the bones, entered the chest cavity, and hit the heart.

Half of the heart of the "Iron Winged Batworm" king was shot and turned into a piece of blood and minced meat.

The third-level sniper bullet passed through the muscles and then stuck into the bones after the "Iron Winged Batworm" king.

David's judgment was correct, because it was not the best shooting distance for customized super-caliber sniper rifles. This third-level sniper bullet did not fully reach the optimal speed point, and its power was not fully utilized.

Therefore, this third-level sniper bullet cannot even penetrate the body of the "Iron Winged Batworm" king, which shows this.

However, the results of the battle were still good. David was sure that this sniper successfully hit the heart of the king of "Iron Winged Batworm".

"Squeak!" Out of David's expectation, the king of the "Iron Winged Batworm" did not die immediately, but instead used all his strength to make a wave of screams.

This wave of calls was a sound wave attack inspired by the king of "Iron-winged Batworm". David could almost see a transparent ripples rushing towards David with the king of "Iron-winged Batworm" as the starting point.

It was at this time that the sniper sound of customized super-caliber sniper rifles also spread through the hole to the king of "Iron Winged Batworm".

Two sound waves collided, and the sniper sound of customized super-caliber sniper rifles was instantly dispersed, and transparent ripples continued to rush towards David.

David could not retreat at this moment. He didn't understand why the "Iron Winged Batworm" king's heart had been hit, so he still had the strength to attack.

The speed of transparent ripples is too fast, and he doesn't have much time to retreat, not to mention that once he gives in, the king of "Iron Winged Batworm" may have a chance to ease, and there may be a second and third attack.

In addition, this is the nest of the "Iron-winged Batworm", David cannot guarantee how many "Iron-winged Batworms" there are. This sound will definitely attract the rest of the "Iron-winged Batworms".

David threw down his customized super-caliber sniper rifle, grabbed the third-level heavy axe, and rushed towards the transparent ripple.

The half-step perfect level mastery of the heavy axe allowed David to see some gaps in the transparent ripples when he was about to collide with the transparent ripples, and he instinctively cut down with a heavy axe.

The third-level heavy axe slashed in through the largest gap, and the transparent ripples were divided into two, rushing past David.

David's whole body was shocked, and he felt that the bones in his body seemed to be dissipating. He almost had no hesitation. A bottle of "Immortal Holy Water" was injected into his body.

David probably is the only one who can use the "Holy Water of Immortality" as a healing potion.

Anyone from the Interstellar Federation would wish to strangle David to death when he saw David using the "Holy Water of Immortality". This is an extreme waste.

The "Elderless Holy Water" entered the body, and the body, which had lost its strength, was washed away by a warm energy, and regained its strength again.

Compared to David's body, his soul was not greatly affected. The worst impact was split by his slight perfect-level heavy axe. In addition, the two protections of the soul fortress and the soul crystal in his soul made his soul not hurt.

The only regret is that David's soul crystal that had been condensed for many days broke. Fortunately, as long as David continues to practice the "Crystal Meditation Method", he can recover.

Outside David's soul fortress, the crystal barrier turned into a few starlights during the impact, and the remaining sound waves hit the soul fortress, and the sound waves themselves turned into a slight energy dissipated.

The collision between David and the high-frequency sonic attack was only one second. Although David looked very relaxed in this second, no matter whether he lacked the half-step perfect level heavy axe to master, the "Underage Holy Water" or the powerful soul fortress, it would cause him to be severely injured or even die in this wave of high-frequency sonic attack.
