Shadow waiter was one hundred meters above his head, observing the surrounding environment, while David was wearing a 'camouflage cloth' and running fast.
He did not choose to enter the Zerg-occupied area from the direction of the fourth frontline base. On the one hand, he did not want to kill too many third-level Zergs in this area. This time he needed the blood of a large number of third-level Zergs.
If he hunts and kills the third-level Zerg in the Zerg-occupied area outside the fourth frontline base, based on his efficiency, it is estimated that it will be difficult to find the third-level Zerg to kill when he comes out with four extraordinary people next time.
On the other hand, if David made any major moves in the Zerg-occupied area outside the fourth frontline base, he was worried that the fifth-level Zerg 'Half-body Spider Queen' would be suspicious.
Although David also knew that the 'Half-length Spider Queen' would most likely not attach so much importance to him, he did not dare to relax in the slightest.
Shadow waiter's observation range is very far, and David saw a third-level Zerg 'phantom millipede' eight kilometers away through Shadow waiter's eyes.
This third-level zerg acting alone is the best hunting target for David.
David lightened his feet and walked in the direction of the 'Phantom Millipede'.
The 'phantom millipede' was eating, and looked up from time to time to look around, seemingly very vigilant.
Its food is a small unmanned aerial vehicle. It is estimated that after the small unmanned aerial vehicle was shot down, the energy source in it attracted this 'phantom millipede'.
The hard shell of the drone was easily bitten open under the third-grade teeth of the 'Phantom Millipede', exposing the components inside.
The 'Phantom Millipede' took the components inside as snacks, ate it in one bite, and soon ate the internal energy source. It swallowed the energy source directly, and closed its eyes as if enjoying the energy surge in the energy source a feeling of.
The Zerg's food is very mixed, any high-energy substance can become their food, and ordinary Zerg can use any substance as food.
The 'Phantom Millipede' eats relatively delicately. Humans or low-level Zerg are its normal hunting food, and such high-energy items are tooth-beating offerings.
Just as the 'Phantom Millipede' closed its eyes and enjoyed it, a figure suddenly sprang out from the ground under it, and that was David.
After David got close to the 'Phantom Millipede' for three hundred meters, he used 'Underground Sneak' to enter the ground.
Although he has the ability to kill the 'Phantom Millipede' face to face, it doesn't mean that the way of fighting is safe.
David's flaws are obvious. Super equipment and various natural abilities allow him to burst out the damage of the first-level fourth-level Zerg, but his defense cannot even resist the attacks of the third-level Zerg.
Therefore, David will not fight face-to-face with the third-level Zerg unless it is absolutely necessary.
Of course, if someone is there to assist him, he can safely use his own strengths to easily kill the third-level Zerg.
But in such a solo operation now, an underground sneak attack is the most correct choice.
Use 'Underground Stealth' to come behind the 'Phantom Millipede', and then open the 'Spiritual Ax Technique' to connect the spiritual thread to the body of the 'Phantom Millipede'.
There was no one around, so David could safely and boldly use the fifth-grade ax blade.
When the 'Phantom Millipede' felt the danger, a golden ax light swept across, and the head of the 'Phantom Millipede' flew up. During the whole process, this 'Phantom Millipede' didn't even have a chance to fight back.
At the moment when the head of the 'Phantom Millipede' flew up, David took out the vat he had prepared earlier from the space bag.
He put the vat on the neck of the 'Phantom Millipede', and a large amount of green blood flowed into the vat.
This vat was made by David according to the size of the 'Assassin Mantis' body. If you want to fill the vat with the blood of the third-level Zerg, this is not something that one or two third-level Zerg can do.
After bleeding, David decomposed and put away the two pieces of reinforced meat behind the 'Phantom Millipede', as well as the third-grade materials such as teeth and claws.
Then he used the talent ability of 'Underground Stealth' to bury the body of 'Phantom Millipede' underground.
If the corpse of a third-level Zerg is thrown here, it may be discovered by the Zerg, but if a third-level Zerg disappears, it is difficult for the Zerg to find it.
Shadow Waiter lifted off again, and David continued walking towards the krypton crystal mine on the map.
He is a bit pity, if he can own a top krypton crystal mine of his own, he can use the 'pregnant crystal' to cultivate the 'perfect grade krypton crystal' by himself.
David knew that at least in the federation, it would be very difficult to do this. If the 'pregnant stone' was used to affect the krypton crystal mine, the staff in the krypton crystal mine would definitely see the clues.
Even if these staff members are working for him, there is a great possibility that they will tell about the anomaly, and his 'pregnant spar' may not be guaranteed by then.
Besides, I don't know how long it will take to cultivate a "perfect grade kryptonite" with a "pregnant crystal", but it's better to go to these nine krypton crystal mines to snatch them.
It might be wrong to say 'snatch'. David's method should be called stealing. With his talent, it shouldn't be difficult to steal the 'perfect kryptonite'.
After a day, David came to the first target, a krypton crystal mine 500 kilometers away from the defense line.
From a distance, he saw a large number of caves on the ground. This kind of cave was very familiar to him, and it was the lair of the 'ghost-faced spider'.
The nests of these 'ghost-faced spiders' surround the valley in the middle. These 'ghost-faced spiders' are covered with spider silk around the nests. Anyone who steps on the spider silk will startle the 'ghost-faced spiders'.
There are as many as 10,000 'ghost-faced spiders' here. Once it is alarmed, even Chaofan will be very troublesome, not to mention that there is a fourth-level Zerg here mentioned on the federal map.
David frowned, he didn't like these 'ghost-faced spiders' that burrowed underground, he felt that these 'ghost-faced spiders' invaded his area.
Wherever he went before, he could act freely as long as he entered the ground, but the situation ahead was complicated. He could only hope that the 'ghost-faced spider' would not make its lair ten meters deep underground.
A group of 'iron-winged bats' flew from the sky in the distance, causing David to immediately lower his body and let the 'camouflage cloth' perfectly hide his figure.
The group of 'Iron Wing Bats' flew over the nest of 'Ghost Face Spider', and some of the 'Iron Wing Bats' even landed on the ground to rest.
Just when David thought that the two Zergs would fight, who would have thought that the 'ghost-faced spider' seemed to have not found the 'iron-winged bat'.
This is absolutely abnormal, 'Iron Winged Bats' are extremely xenophobic Zerg, they will drive out other Zerg in their territory, and 'Ghost Face Spider' will not tolerate other Zerg standing on their spider silk.
There is only one possibility. The 'ghost-faced spider' and the 'iron-winged bat' are a community. Combined with the krypton crystal mine here, it is not difficult to guess that they are all the guardians of the krypton crystal mine.
Neither the sky nor the ground can be entered quietly. David opened the 'underground sneak', and then his body submerged into the ground and entered the ground.
Shadow waiter was not above the ground this time, but underground to explore the environment ahead for David.
The 'ghost-faced spider''s lair has laid a labyrinth-like burrow underground in front of it. The 'ghost-faced spider''s lairs are all interconnected, not as simple as on the ground, but underground is a huge project.
During Shadow Waiter's investigation, the walls of these 'ghost-faced spiders' lairs are covered with spider silk. As long as they come into contact with the walls of these underground lairs, the 'ghost-faced spiders' will find them.
You must know that the walking method of the 'Ghost Face Spider' relies on special limbs, which is completely different from ordinary contact.
David drew a simple underground map on the visor based on Shadow Waiter's investigation ahead.
He carefully avoided the caves of the 'ghost-faced spiders'. In these burrows, there were 'ghost-faced spiders'.
The 'Ghost Face Spider''s lair is very deep, more than ten meters, which makes David have to sneak outside the complex underground maze.
This complicated environment made it impossible for David to pass quickly, so he could only sneak for one minute, then rest and wait for five minutes.
This distance of about three kilometers took David a full hour.
When he found that there was no complex underground labyrinth ahead, David knew that he had passed the 'Ghost Face Spider''s lair area.
Shadow Waiter then left the ground and returned to the ground.
Sure enough, there were no more holes on the ground ahead, and David saw a large number of 'Burst Jets', among which there were many elite-level 'Burst Jets'.
It can be imagined that once it wants to approach here from the air, it will first be attacked by the 'Iron Winged Bat Bug', and then the 'Burst Jet Bug' will concentrate its energy on attacking the sky target.
With the concentrated attack power of so many 'explosive jet bugs', even Chaofan couldn't bear it.
David didn't dare to leave the ground at this time. Don't look at the fact that these 'explosive jet bugs' have no melee ability, but as long as one is killed, it will explode immediately. Even a secret assassination will alarm the Zerg here.
The helpless David can only continue to sneak underground, but this time he can pass quickly.
Next, David saw that there were six 'armor-piercing beetles' and six 'giant pincer flame worms' at the entrance of the valley, blocking the passage leading to the valley.
Under Shadow Waiter's observation, the rest of the places are covered with spider silk, I believe those places will be discovered even if you try to get close to them, let alone pass through.
David continued to look inward, he was a little curious, there are so many Zerg guards in this krypton crystal mine, and how much Zerg value the 'perfect krypton crystal'.
He mentally felt the big bucket in the space bag. After five hundred kilometers, he killed as many as seven third-level Zerg, and the blood of these seven third-level Zerg was in this big bucket.
Soaked in blood is the corpse of that 'Assassin Mantis', and a strange pattern is on the corpse of 'Assassin Mantis'.
It's a pity that this is in the space bag. David originally thought that the preliminary treatment of the corpse of the 'Assassin Mantis' could be completed in the space bag, but he was wrong. The patterns and blood in the space items are still and have no effect.
Shaking his head, David thought whether he found the 'Perfect Grade Kryptonite' here or not, he still needed to find a place to take out the vat and let the 'Assassin Mantis' corpse complete the first step.
David sneaked in again. The defenses here are indeed very tight, but these defenses are based on visible enemies. If David sneaks in silently from the ground, he will not be able to find them.
David entered the valley very easily. The valley was very empty, only some mining ants were working.
Mining ants are just a first-class Zerg, they have no fighting power, but they are the best miners, they can work tirelessly, and their food is just useless leftovers from minerals.
This is the first time for David to see the top-level krypton crystal mine of Battle Star. The minerals here are completely different from the krypton crystal mine of Guardian Star.
On the ground in the valley, exposed krypton crystal ores can be seen everywhere, and there are many top krypton crystal ores in these krypton crystal ores.
How much kryptonite can be produced in such a large valley, David was shocked.
The job of the mining ants is to dig out the krypton crystal ore with sufficient energy, and then send it to one place to pile up.
The shadow waiter sent a reminder, David quickly put his mind into the shadow waiter, and through the eyes of the shadow waiter, he saw a cave at the end of the valley.
David didn't think that the 'perfect kryptonite' would be produced in the open area of this valley. If it was produced here, the fourth-level Zerg would stay here.
No fourth-level Zerg was seen in the valley, so of course the fourth-level Zerg was in the cave ahead.
David continued to 'sneak underground'. He felt the countless krypton crystal ores around him. The krypton crystal ores here had obviously not been mined too much, otherwise there would not be so many krypton crystal ores left underground.
And the number of mining ants is not much, only some krypton crystal ores exposed on the surface and with sufficient energy are mined away.
According to David's estimate, the reason why the krypton crystal ore here is not mined in a large area is probably because of the "perfect grade kryptonite". According to David's estimate, the production of "perfect grade kryptonite" is likely to be These krypton crystal ores are required to exist.
Otherwise, given the Zerg's thirst for energy, no matter how large the krypton crystal mine is, it will only take a short time to be dug out.
The growth of Zerg needs energy, and the energy contained in ordinary krypton crystal mine is exactly what most Zerg need.
David continued to move forward, but he stopped when he was still a hundred meters away from the entrance of the cave.
Because when he was about 100 meters away, his head felt dizzy, and the crystal outside the soul fortress seemed to be shaking constantly as if it was being attacked.
This is a kind of spiritual attack, and such a strong mental attack must be issued by a very powerful fourth-level Zerg.
David didn't expect that what he thought was a simple stealing operation would be blocked when he reached the door.
He didn't dare to force his way in either. Maybe his soul fortress could withstand spiritual attacks, but when he really suffered spiritual attacks, he couldn't keep his hidden breath.
Then David will have to face this terrible fourth-level Zerg that can use its mental unconsciousness to attack hundreds of meters around it while it is still in the cave. The Zerg is almost born to restrain an existence like him.
