Chapter 1222 Reverse Operation (First and Bigger Chapter, Please Give Me a Monthly Vote)

Xia Chujian said: "What's the difference between one and many? Qilu, don't worry about it, just kill them!"

Although Qilu said that the bioelectricity of these Zergs is exactly the same, Xia Chujian feels that her feelings about these Zergs are not exactly the same.

She can feel more maliciousness in some Zergs, but she can only feel ordinary maliciousness in some Zergs.

But without exception, they all have the same maliciousness and instinct of creatures seeing food and toys.

Xia Chujian can't stand it.

Her mechanical arm raised, and the Judge No. 1 sniper rifle began to harvest lives like a sickle in the hands of the god of death.

Xia Chujian took this opportunity to start shooting in this spacious energy room.

After a few gunshots, at least twenty Zerg nest builders died under her gun.

Without exception, at the beginning, the shells of these Zerg nest builders looked intact, but the inside had exploded into a ball of flesh and blood!

Then, the shells were soon stained by black matter and finally completely carbonized!

There were about four or five hundred Zerg nest builders in the energy room.

Xia Chujian killed the Zerg nest builder who had the most malice towards her, and then killed twenty of the strongest and tallest Zerg nest builders. The remaining Zerg nest builders finally came to their senses.

They were still at a loss, and didn't know what to do. They could only curl up their bodies instinctively.

Suddenly, the ground in the spacious energy room was 80 centimeters higher...

Xia Chujian: "..."

There was no fluctuation in her heart, and she even wanted to laugh.

But after taking a closer look at the current state of these Zerg nest builders, she felt that it was indeed tricky.

Because now, they have retracted their tentacles.

The whole body was like a whole piece of stone, and there was no breakthrough point.

Xia Chujian changed the bullet without saying a word.

She pressed a black-silver bullet into the barrel of the sniper rifle.

Click!

With a gunshot, the black-silver bullet shot at the Zerg nest builder closest to her.

The black-silver bullet exploded on the shell of the Zerg Nest Builder, and then the black mist quickly spread to the entire body.

Then, the shell of the Zerg Nest Builder seemed to soften, like hard soil gradually turning into black mud.

Five minutes later, the entire Zerg Nest Builder was completely dissolved by the black-silver bullet.

After the black-silver bullet was dissolved, a lot of it was also consumed.

Xia Chujian waited for another fifteen minutes, and the remaining black-silver bullet liquid dissolved the three Zerg Nest Builders next to the previous Zerg Nest Builder.

Looking at this "price ratio", Xia Chujian shook his head and said regretfully: "It took 20 minutes for a black silver bullet to dissolve four Zerg nest builders."

"The efficiency is too low."

"Qilu, why do you think so? This Zerg nest builder is harder to dissolve than the relic species?"

Qilu said: "Master, it should be the influence of the Zerg shell."

"The relic species are all carbon-based organisms, and they don't have shells like Zerg nest builders. So the black silver bullet can target their biological characteristics and dissolve quickly."

"At present, the main obstacle to fighting against the Zerg is their shell."

"This stone shell does not seem to be a product of this world."

"Compared with the insect shell in the Beichen galaxy, the gene chain is already very different."

As Qilu spoke, he showed Xia Chujian a simple biological gene chain analysis he had just done on the eyepiece display.

Xia Chujian was amazed and said, "Qilu, I didn't expect you to do genetic testing!"

Qilu said proudly in his childish voice, "Master, Qilu seems to have evolved! The database has been unlocked more!"

Xia Chujian praised it, "Come on, Qilu!"

Qilu's childish voice was loud and excited, "Thank you for the compliment, Master! Qilu will definitely work harder!"

Xia Chujian just said it casually.

Her attention was still on those Zerg nest builders.

If these guys were determined to play this "turtle" policy, then for a while, humans really couldn't do anything about them.

Xia Chujian showed her long dagger made of crocodile dragon teeth again.

She flew up, walked in the air, and the dagger in her hand flashed a bright knife light, and swung down.

The crocodile dragon tooth dagger, which was more powerful than a sniper bullet, could indeed cut the Zerg nest builder.

Although they have curled themselves up, their bodies are all covered with gray stone shells, but in front of Xia Chujian's crocodile dragon tooth dagger, the stone will be cut in half!

However, Xia Chujian can feel an indescribable sense of obstruction, a feeling that she doesn't have when cutting stones with her crocodile dragon dagger.

She took some effort to cut off the head of a low-level Zerg nest builder.

If this were on the battlefield, she would have been surrounded by other Zergs long ago. She would definitely not be like the low-level Zergs in this room, who only know how to curl themselves up, so they are completely unfeasible to kill enemies on the battlefield.

And after cutting off a Zerg nest builder, Xia Chujian found that her spotless dagger seemed to be a little darker than before.

She felt a little distressed and hurriedly put away the crocodile dragon tooth dagger.

She thought that this dagger could indeed deal with this kind of Zerg nest builder, but the efficiency was not high, and it did not meet the mass destruction effect she needed.

Then how to deal with these Zerg nest builders with hard shells?

Do we have to use high-yield explosives to solve the problem like we did before in space?

But these Zerg are not in separate starships, but in the basement of the manor.

If high-yield explosives were used here, the manor would be wiped out.

The manor is gone, and they have to stay in that narrow aircraft. They may not be able to move in this place for a month, a year, or several years.

Xia Chujian intuitively didn't want to do this.

Therefore, she did not want to continue using high-yield explosives to deal with these Zerg.

And it's not as airtight as a starship.

If the operation is improper and one or two of these Zerg escape, then her sin will be great...

So is there any way to solve it once and for all?

Xia Chujian observed carefully.

She noticed that when these lowly insect nesters curled up, their shells looked like rocks.

And the shape is quite regular, square and square.

They all stacked up, so the ground was eighty centimeters higher!

I don’t know how much explosives would be used to create such a Zerg shell...

Xia Chujian squinted his eyes, as if he remembered something.

Is this seemingly airtight shell really that "dense"?

What kind of thing would it take to penetrate these stone-like shells?

She has killed these Zerg species and knows that they have a hard outer shell but are actually carbon-based organisms inside.

As long as they are carbon-based organisms, there is nothing that human weapons cannot deal with.

Now the human race's war against the Zerg seems to be losing ground, mainly because of their outer shell...

Xia Chujian stared at the "ground" with hatred, thinking that even crab shells can be peeled off to eat crab meat, and you bugs are just large proteins with shells!

However, it seems that only the softest and softest things can handle the most difficult and hard things.

No matter how hard the rock is, doesn’t it still have holes?

It's just that the holes are very small, and gas can penetrate them.

gas……

In the flash of lightning, Xia Chujian thought of her method of dealing with the ship of nesters in the starship.

What if we do the reverse operation?

She suddenly asked: "Qilu, these Zerg nest builders, they don't actually breathe oxygen, right?"

After a while, Qilu said, "Probably not. The oxygen content on that starship was so low that it was negligible."

"At the time we thought the oxygen-producing equipment on the starship was broken."

Xia Chujian nodded repeatedly: "Yes, yes! I felt something was wrong at that time."

"Because those Zerg nesters don't seem to need to breathe oxygen to survive at all!"

There was almost no oxygen in the cargo compartment of the spacecraft at that time, but the Zerg nesters could still sit together and move around freely.

Qilu added: "Before we entered this basement room, the small nuclear fusion engine here was not started."

"A big hole was also punched through the roof, and the fully enclosed self-circulation system of the entire manor was completely destroyed. Therefore, the air inside the manor is the same as the air outside the manor."

"The air here on the asteroid has very low oxygen content, but these Zerg nesters have no problem at all."

"From this perspective, these Zerg nest builders, unlike the creatures in the Beichen Galaxy, do not mainly rely on oxygen for breathing."

Xia Chujian nodded: "I think so too."

"With my rudimentary biological knowledge, I know that there are anaerobic bacteria among bacteria."

Qilu said: "There are also many types of anaerobic bacteria."

"Obligate anaerobic bacteria are extremely sensitive to oxygen, which is toxic to them and can only survive in an oxygen-free environment."

"Facultative anaerobic bacteria can grow in both aerobic and anaerobic environments, and are very tenacious in their adaptability to the environment."

“There are also aerobic-tolerant anaerobic bacteria and microaerophilic bacteria.”

"Aerotolerant anaerobic bacteria do not depend on oxygen, but can survive in an aerobic environment and will not be killed by oxygen."

"Microaerophilic bacteria are special. They need extremely low concentrations of oxygen to survive and cannot grow under the oxygen levels in the normal atmosphere of the Beichen Galaxy."

"If the oxygen concentration is too high, it can also inhibit or kill them."

"What kind of anaerobic bacteria does the owner think these insect nest builders are similar to?"

The corner of Xia Chujian's mouth twitched, thinking to herself that her biological knowledge was really very superficial.

She only remembered that there was anaerobic category among bacteria, but did not remember that under this category, there were many different subdivisions.

Xia Chujian said: "What if they are not anaerobic at all? Of course, oxygen is definitely not the main gas they breathe, because they can survive freely in almost an oxygen-free environment."

"You see they can be directly exposed to the asteroid's atmospheric environment and survive for such a long time."

"There is no need for this manor's fully enclosed self-circulating oxygen production system."

"It doesn't matter to them whether the roof is repaired or not."

A thought suddenly came to Xia Chujian's mind: Since it doesn't matter to these low-level Zerg nest builders whether the roof is repaired or not, why do they have to work so hard to transport those building materials thousands of miles away?

Before she had time to think carefully, she heard Qilu talking and suddenly forgot what she was thinking.

Qilu said: "So they are similar to oxygen-tolerant anaerobic bacteria?"

Xia Chujian came back to his senses and said deeply, "Isn't that right? You'll know after you try it."

A bad smile appeared on her face: "Qilu, tell me, what will be the consequences if we increase the oxygen input to this energy room?"

Qi Lu's childish voice became excited: "You can give it a try!"

Xia Chujian immediately drove his Xuannv Qingyao Titanium Mech to the center of the energy room.

There was a room surrounded by transparent glass.

Xia Chujian placed the mechanical palm on the glass.

Qilu immediately analyzed: "Master, the strength of this glass is very hard, reaching the strength of diamond."

"In a sense, this is a diamond with not very high purity."

"The instrument inside is a small nuclear fusion engine."

"As long as it is turned on, the fully enclosed self-circulating system of the entire manor will start working again."

"Including the oxygen production system."

Xia Chujian asked: "Where is the oxygen production system?"

Qilu said: "...It should be in the next room."

"Qilu can detect that there are many rooms here with various instruments."

Xia Chujian said: "Are there so many Zerg nest builders next door?"

Qilu said: "I haven't detected it."

Xia Chujian said: "Will it be like now, they rolled themselves into stone, without revealing any breath of life, so you can't detect it?"

Qilu said: "...Master, it's not impossible."

Xia Chujian said: "That's fine, don't worry about them, we will act according to the plan."

As she said, she had asked Qilu to open the diamond glass door with a code and walked in.

It was also Qilu who operated her mecha arm to start the small nuclear fusion engine.

Then, the lights in the entire energy room were bright, much brighter than the faint light from the white stone before.

Xia Chujian closed the door here and went to the next room.

The floor of the next room was not 80 centimeters higher than the outside of the room, so Xia Chujian judged that the floor here was real ground, not the Zerg nest builder.

In addition, Qi Lu did not detect any biological life fluctuation signals, which also gave her some confidence.

Xia Chujian quickly found the oxygen generator here. After starting it, she found a plastic pipe with a diameter of 10 centimeters in the room and connected it to the oxygen generator.

There were many kinds of tubular objects in this room, like a warehouse for stacking spare pipe equipment.

It was just a bargain for Xia Chujian.

She started the mechanical arm of the mecha, switched the front end of the arm to a drill, drilled a hole in the wall, and directly connected this pipe to the opposite energy room.

The next step was to turn on the oxygen generator in this room to the maximum!

More huge amounts of oxygen were transported to the energy room next door.

Soon, Xia Chujian could hear the sound of violent collisions, roars, and scuffling sounds coming from the next room.

Xia Chujian's heart skipped a beat and he said, "...Is it done?"

"Are these Zerg nest builders really not adapted to an environment with particularly rich oxygen content?!"
