David called back the shadow waiter, and the shadow waiter took the third-level heavy ax out of the space item, and David held it in his hand.
This was his worst plan just in case. After making a mistake, he quickly killed the 'Iron Winged Bat Worm' who was guarding the goal.
David pulled out the 'slumber pattern' from the wall of the soul fortress, and the 'slumber pattern' flew slowly into the cave entrance at a slow speed.
At the same time, the shadow waiter also flew into the entrance of the cave, and David relied on the shadow waiter's eyes to control the 'Slumber Pattern' to fly towards the 'Iron Wing Bat Worm'.
Apparently, this 'Iron Winged Bat' didn't expect that someone would plot against it. It has always maintained a sound wave transmission around it, and within the range of the sound wave, as long as any creature appears, it will be discovered by it.
So don't look at the 'Iron Winged Bat' not looking around, but in fact it knows everything around it.
This is a natural ability, in a dark environment, using sound waves instead of eyes.
But this innate ability can only have effects on entities, whether it is the 'Slumber Pattern' or Shadow Waiter, they cannot be detected by this innate ability.
The 'slumbering pattern' flew into the body of the 'Iron Winged Bat'. Obviously, this first-level 'Iron Winged Bat' did not have too much soul strength, and even the 'slumbering pattern' could not be found, let alone Resist the 'slumber pattern'.
After a minute, the 'Iron Wing Bat Worm' opened its iron wings and opened its eyes to look around, and David walked directly into the cave at this time, the 'Iron Wing Bat Worm' didn't seem to see David.
At this time, there was a strange connection between the 'Iron Winged Bat Worm' and David, and the 'sleeping pattern' in the soul of the 'Iron Winged Bat Worm' had long been transformed into a 'bewitching pattern' after this minute ', this 'Iron Winged Bat' became David's puppet.
David did not take this 'Iron Winged Bat', but left it here.
Along the inward passage of the cave, David walked 20 meters, and there was no 'iron-winged bat insect' in this distance.
After passing twenty meters, the space suddenly opened up, and a space about thousands of cubic meters appeared.
This is a huge cave. Originally, it should be dark and dark, but some light spots on the walls of the cave make the cave bright.
Shadow waiter flew to a spot of light, but saw the real body of the spot, it was a piece of krypton crystal source mine, the quality was very good.
The light spots here are all krypton source ores, and these krypton source ores provide light for this space.
On the wall of the cave, there are dozens of openings. There is also no 'Iron Winged Bat' in the cave, but some traces of life left by the 'Iron Winged Bat' can be seen.
The bottom of the cave is full of various bones, excrement, etc. If David hadn't had an air filtration system with a custom-made exoskeleton armor, he would have been overwhelmed by the smell in the cave by now.
David looked at the dozens of holes, his face was a little ugly. He had delayed a lot of time before, giving the king of the 'Iron Winged Bat Worm' a little time to breathe. When he found the king of the 'Iron Winged Bat', the king of 'Iron Winged Bat' recovered most of his injuries.
At that time, it is difficult to say whether he will kill the king of the 'Iron Winged Bat' or the king of 'Iron Winged Bat' will kill him.
Just when David was anxious, Xiaobai in the custom-made exoskeleton suddenly twisted his body.
David connected mentally. You must know that Xiaobai is very quiet on weekdays, and usually doesn't disturb David. If he moves now, he should have discovered something.
Sure enough, Xiaobai issued a warning to David, and there was an aura that made him extremely afraid.
"Xiaobai, do you know the direction of this breath?" David tried to ask mentally.
Xiaobai immediately passed a direction to David, and there happened to be a hole in that direction.
David calmed Xiaobai mentally, then soared into the air and flew towards the entrance of the cave.
Of course, Shadow Servant flew over one step earlier, discovering any possible danger for David in advance forty meters away.
Flying to the entrance of this cave, David immediately sensed the thick krypton crystal energy breath. With the restrained nature of krypton crystal energy, being able to have such a strong energy breath can only show that the number of krypton crystals here has reached a very terrifying level .
When Shadow Waiter entered the entrance of the cave, he saw that the cave wall was densely packed with krypton crystal source mines, which were countless times denser than the big cave outside.
It is no wonder that there is such a strong atmosphere of krypton crystal energy. There are so many krypton crystal source mines, which also makes David confident that this is the cave of the king of the 'Iron Winged Bat Worm'.
The shadow waiter looked inward, and there was no need to search any further. Just two hundred meters inside, the king of the 'Iron Winged Bat Worm' was stuffing a piece of krypton crystal source into the entrance.
At this time, the king of the 'Iron Winged Bat Worm' was in much better condition than before, especially the damage on the pair of iron wings was gone.
As a flying Zerg, the king of the 'Iron Wing Bat Bug' instinctively prioritizes treatment over the most important iron wing, so the iron wing can be repaired the fastest.
If David hadn't seen that the deep wounds on the king of the 'Iron Winged Bat Worm' hadn't healed yet, he would have turned his head and left right now.
No matter how much wealth one has, or how alluring the light ball of knowledge of the king of the 'Iron Wing Bat Bug' is, it is far less important than one's own life.
The king of 'Iron Wing Bat Worm' seemed not satisfied after taking a piece of krypton crystal source ore, so he picked up another piece of krypton crystal source ore and swallowed it again, then hung his body upside down, relaxed his whole body and began to digest krypton crystal Source ore, speed up the healing of injuries.
This group of 'iron-winged bats' has not been here for a long time. If it had been a long time, they would have been discovered by the academy base long ago. How could the academy base allow such a dangerous group of insects to settle here.
It is also true that this krypton crystal mine has not been mined much.
Although the Zerg's devouring ability is extremely powerful, only a small number of particularly powerful 'iron-winged bats' can swallow the krypton source ore.
The rest of the 'iron-winged bats' still need to be passively absorbed in the krypton crystal energy environment in order to grow slowly.
The king of the 'Iron Winged Bat' returned here immediately after the group was wiped out. The reason is that there is hope for the group here. A batch of eggs with the genetic inheritance of the 'Iron Winged Bat' are here, waiting to hatch at any time .
The king of the 'Iron Winged Bat Bug' needs to return here to guard the eggs. Without its guardianship, this place will be targeted by the rest of the Zerg at any time.
The distance from the entrance of the cave to the king of the 'Iron Winged Bat Worm' is 200 meters. To be honest, this is not a particularly good sniping distance.
There is no sniper position at a distance, so it is impossible to snipe at all, so if David wants to snipe, he can only be at the entrance of the cave.
Fortunately, the king of the 'Iron Winged Bat Worm' hung upside down and remained motionless. For David, this was a stationary target.
Only two hundred meters away, David was wearing a 'camouflage cloth', carefully lowered to the entrance of the cave, and then lying on the ground, he put the third-grade heavy ax aside, and took off the custom-made super-large-caliber sniper rifle behind him.
David knew that he only had one chance. With a distance of two hundred meters, the king of the 'Iron Wing Bat Worm' would never give him a second chance.
Gently pressing the third-grade sniper bullet, David looked at the king of the 'Iron Winged Bat Worm' through the sniper scope.
Although the king of the 'Iron Winged Bat' is covered by its iron wings and his body cannot be seen, David has already recorded the wounds on the 'Iron Winged Bat'.
At this time, under David's observation, he could directly judge the wound behind the Iron Wing of the 'Iron Winged Bat Worm' King through comparison, and find the best sniper position.
Originally, sniping its head was the best choice, but David worried that this 'Iron Winged Bat' was already a third-level Zerg, so under the multiple protections of its skin, bones and iron wings, this distance is not the best Even with a third-grade sniper bullet, David is not confident that he can 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 'Iron Winged Bat Worm' king. On this straight line, only the iron wing is protected. Bones are avoided.
This time David didn't even block the sound of the custom-made super-large caliber sniper rifle. He thought of the particularly eye-catching ears of the king of the 'Iron Wing Bat Worm'. Two hundred meters, but there is almost a straight passage in the middle, which is very convenient for sound transmission.
There was a loud "boom", but the third-grade sniper bullet was fired faster than the sound, and the speed of the third-grade sniper bullet was much faster than the sound.
The sniper bullet jumped over a distance of 200 meters the moment it left the sniper barrel, and appeared outside the iron wings of the 'Iron Wing Bat Worm' King.
The king of the 'Iron Winged Bat Worm' has actually maintained sound wave transmission all the time, but it was injured, so he controlled the sound wave transmission within a range of 100 meters.
This is also the reason for the confidence in the safety of this lair. There are 'Iron Winged Bats' guarding outside. If there is an enemy, it will make a special sound, and it can receive it immediately.
When the third-grade sniper bullet entered one hundred meters, the king of the 'Iron Winged Bat Worm' woke up. Before he could move his body, the third-grade sniper bullet hit its iron wing.
The Iron Wing was unable to defend. After the third-grade sniper bullet consumed some of its impact, it punched a small hole in the Iron Wing and continued to shoot towards the body of the 'Iron Wing Bat Worm' king.
As David expected, the third-grade sniper bullet shot into the muscle without skin protection, passed between the bones, entered the chest cavity, and hit the heart again.
Half of the heart of the king of the 'Iron Winged Bat Worm' was shot and turned into a piece of bloody flesh.
The third-grade sniper bullet passed through the muscle behind the king of the 'Iron Winged Bat Worm' and then got stuck in the bone.
David's judgment was right, because it wasn't the best shooting distance for a custom-made super-large-caliber sniper rifle. This third-grade sniper bullet didn't fully reach the optimal speed point, nor did it fully exert its power.
So this third-grade sniper bullet could not even completely penetrate the body of the king of the 'Iron Winged Bat Worm', which shows this point.
But the results are good, David can be sure that this time the sniper successfully hit the heart of the 'Iron Winged Bat Worm' King.
"Squeak!" Contrary to David's expectations, the king of the 'Iron Winged Bat Worm' did not die immediately, but let out a wave of screams with all his strength.
This wave of screams is the sonic attack of the 'Iron Winged Bat' king with all his strength, and David can almost see a transparent ripple coming towards David starting from the 'Iron Winged Bat'.
At this time, the sniping sound of the custom-made super-large-caliber sniper rifle also reached the king of the 'Iron Winged Bat Worm' through the entrance of the cave.
The two sound waves collided, and the sniping sound of the customized super-caliber sniper rifle was instantly dispersed, and the transparent ripples continued to rush towards David.
David couldn't retreat now, he didn't understand why the king of the 'Iron Winged Bat Worm' had been hit in the heart, why he still had the strength to attack.
The speed of the transparent ripples is too fast, even if he wants to retreat, he won't be able to come in time, not to mention that once he retreats, maybe the king of the 'Iron Winged Batworm' will have a chance to relax, maybe there will be a second and third time attack.
In addition, this is the lair of the 'Iron Winged Bat'. David can't guarantee how many 'Iron Winged Bats' there are. This kind of noise will definitely attract the rest of the 'Iron Winged Bats'.
David threw down the customized super-large-caliber sniper rifle, grabbed the third-grade heavy axe, and rushed towards the transparent ripples.
The half-step perfect mastery of the heavy ax made David see some gaps in the transparent ripples when he was about to collide with the transparent ripples, and he instinctively struck down with a heavy axe.
The third-grade heavy ax pierced through the largest gap, and the transparent ripples were divided into two, rushing past David.
David's whole body was shaken, he felt that the bones of his whole body were about to fall apart, almost without any hesitation, a bottle of 'Holy Water of Immortality' was poured into his body.
David is probably the only one who can use the 'Holy Water of Immortality' as a healing potion.
Anyone from the Interstellar Federation would want to strangle David if they saw David using the 'Holy Water of Immortality' like this. This is an extreme waste.
The 'Holy Water of Immortality' entered the body, and the body that had lost its strength was washed by a wave of warm energy and regained its strength.
Compared with David's body, his soul did not suffer much impact. The most serious impact was split by his half-point perfect level heavy axe, coupled with the double protection of the soul fortress and soul crystal in his soul. , so that his soul was not hurt.
The only pity is that David's soul crystal, which he had condensed for many days, was broken. Fortunately, as long as David continues to practice the 'crystal meditation method', he can recover it again.
Outside David's soul fortress, the crystal barrier turned into a little bit of starlight and dissipated in the impact, and the remaining sound waves impacted on the soul fortress, and the sound waves themselves turned into traces of energy and dissipated.
The collision process between David and the high-frequency sonic attack was only one second. During this second, although David looked relaxed, in fact, no matter whether he lacked half a step to master the perfect heavy axe, the 'Eternal Holy Water' and Any one of the powerful soul fortresses would cause him to be seriously injured or even die in this wave of high-frequency sound wave attack.
