My apocalyptic heroine has come true

The brother and sister who followed closely behind glanced at each other.

They had also seen the mutant wolf lying on the ground.

The appearance of this kind of thing in the wilderness is a nightmare for some shelters with weak defenses and leaky walls.

"GP-2, even close to level 3."

Shi Yi walked forward and took out a short dagger from his waist.

The wolf's head had been separated from the body, but Shi Yi still squatted down, held the dagger and stabbed it hard into the broken spinal cord in the head.

The wolf's paws, which had been blown to pieces, flapped their wings instinctively a few times before it died completely.

"Do you know these species?"

Xia Xiaochi on the side asked curiously.

Although Xia Xiaochi herself also had the habit of finishing off the enemy, she mostly stabbed the head or heart. She had never seen a technique like this one that stabbed the spine.

"Spinewolves, that's what the hunters call them... They're above GP-2. Besides their formidable physique and aggressive nature, their greatest characteristic is that when they lose their heads, their spinal cords become exposed and harden into a 'second brain.' This second brain not only allows them to completely control their bodies and continue their killing spree, but also ignores all pain. Often, they're at their strongest when they're headless."

Having said that, Shi Yi glanced at the broken body of the wolf.

Apparently, before it could make a second kill, more firepower had already shattered its body.

"This type of mutant species often resurrects from the dead. If you want to prevent this from happening, pierce the weapon into their spinal cord. After killing the spinal nerves, they will die completely." Shi Yi turned around and said to Xia Xiaochi.

Xia Xiaochi nodded seriously.

She has no experience in this area and really needs to learn more.

"How do you know so much about this... Do the residents of Shelter 2737 often come into contact with this mutant species?"

Xia Xiaochi squatted down, smashed the wolf's head open and stuffed it into a sack, then asked casually.

Upon hearing this, Shi Yi shook his head helplessly.

"Of course, the residents of ordinary shelters wouldn't know about this mutant species..."

"My sister used to be a hunter!" Shi Si on the other side answered quickly.

Xia Xiaochi was a little surprised, and then he re-examined the woman in front of him.

The woman looked young, probably around 2737 or . Judging by her attire yesterday, Xia Xiaochi assumed she was a miner from Vault .

Now it seems that the muscle lines she has gained through regular exercise were not obtained from mining.

"...Before, I was mainly responsible for logistics."

Shi Yi felt a little embarrassed when Xia Xiaochi looked at her like that.

"Shi Si and I are refugees... We weren't originally residents of Shelter 2737. We've been here for about five or six years."

"Escape?" Xia Xiaochi blinked when he heard that.

There have been countless disasters in the wasteland, and things like "escape" are actually not uncommon.

"Well... a lot has happened."

Shi Yi smoothed the short hair beside her ears and nodded slightly.

at this time.

"Buzzing..."

A small unmanned reconnaissance aircraft approached.

The reconnaissance plane's camera was aimed at Shi Yi's face, and a man's clear and textured voice came out of the speaker.

"What do you mean by GP level? Please tell me in detail."

Shi Yi opened her eyes slightly and looked at the small drone.

This is... the owner of the Ark Shelter?

Chapter 89 Genetic Pollution (46K)

In the Ark Shelter.

The woman sat upright on a plastic chair. In front of her was a long square table with a bottle of vitamin water and some candies on it.

This is the only thing in the Ark Shelter that can be used to entertain "guests".

Xia Xiaochi, sitting across the table, also sat dignifiedly.

She took out a piece of yellowed paper and a charcoal pencil, looking as if she was going to study seriously.

The unmanned reconnaissance aircraft hovered quietly above the two men's heads.

On the other side of the screen, Fang Ming was wearing a Bluetooth headset, holding onto the railings of the wall with both hands, and moving forward with difficulty.

His body's muscle strength is now sufficient to support him to stand up.

However, this standing position didn't last long, and Fang Ming still had to rely heavily on his arms to support his body. The doctor said that after two weeks of recovery, Fang Ming would be able to switch to a different exercise method and walk solely with crutches.

By then, Fang Ming will be able to go to more places.

Every few steps, Fang Ming would stop and rest for a few minutes.

His reliance on the strength of his arms prevented him from looking at his phone while walking, so he could only use the monitoring system of the unmanned reconnaissance aircraft to learn about what was happening in the Ark Shelter.

If Fang Ming wants to talk to people around the shelter, he just needs to press the Bluetooth headset.

To outsiders, it looked like Fang Ming was talking on the phone with his "online girlfriend". As long as they were not allowed to hear the details of the conversation, it would not arouse the suspicion of passers-by.

"Reporting to the commander, Shi Yi is now sitting in front of me wearing a gray long-sleeved shirt... She picked up the vitamin water and took a sip."

"Sir, her breasts are huge."

Fang Ming: “???”

"...I asked you to describe the scene, but I didn't ask you to describe it in such detail."

Fang Ming almost let go of the railing.

Xia Xiaochi knew that Fang Ming was busy at the moment and could not observe with his eyes, so he was very considerate and used words to describe the current situation to Fang Ming.

"G..."

Shi Yi opened her lips slightly and squeezed out a syllable.

She felt uneasy in front of Administrator No. 001.

She had already discussed this with Shi Si before coming to the Ark Shelter.

Demonstrate your 'worth' at all costs and stay in the Ark Shelter.

Shelter 2737 was not a place for them to settle down, and now the shelter was facing potential danger, and the shelter manager did not seem reliable at all.

So, they are looking for new ways out.

The Ark Shelter is their only way out at this stage.

Before Xia Xiaochi could speak, Shi Yi spoke first.

When Xia Xiaochi heard this, his gaze on her chest suddenly shrank and he said in disbelief.

"G...it's actually this big?!"

Fang Ming: "..."

Fang Ming held onto the railing with one hand and silently took his cell phone out of his trouser pocket.

He had seen this woman Shi Yi on his phone yesterday.

But obviously, the other person was not introducing himself or herself about his or her body shape.

Shi Yi cleared his throat and said seriously:

"Master Administrator, you want to know the biological level of the mutant species, right?"

"Uh-huh."

Xia Xiaochi retracted the expression on his face and picked up the black charcoal pencil again.

"I do have a good understanding of the hierarchy of mutant species."

Shi Yi held the bottle of drinking water in her hand and said seriously:

"Ordinary scavengers don't categorize mutant species, but for hunters and some researchers, the biological level of mutant species is very important... On Earth, we mainly categorize them into a three-dimensional hierarchy: depth of biological mutation, ecological niche dominance, and level of quantum consciousness."

"Using acronyms... GP: Depth of Biological Variation, E: Ecological Niche Dominance, Q: Quantum Level of Consciousness."

"The higher the GP value, the higher the genetic pollution index, and the higher the relative degree of biological variation. This directly affects their combat effectiveness and is also the most important point."

"The second is E, ecological niche dominance. This value is of little use to us as a reference, because most of the mutant species we encounter are at the E0 or E1 level, that is, independent individuals acting alone, and they have basically no ecological dominance."

"As for Q, you can think of this value as the 'level of intelligence of a creature.' When a creature becomes exceptionally intelligent, you should be wary... However, this situation is quite rare. Mutated species are generally not intelligent due to innate genetic defects."

Shi Yi finished speaking patiently, and waited until Xia Xiaochi in front of her finished taking notes before she continued.

"Take the most common mutant gray rat at night, for example. Its three-dimensional ranking is GP-0-E1-Q1. The reason is as follows: its mutation depth is very low, with a genetic purity of 99.8%, so GP is 0. E1 is because they live in groups, but they have neither a 'ruler' nor the 'ability to act collectively,' so their impact on the ecosystem is 1, second only to those lone rangers. Finally, Q1, gray rats are almost brainless, but they also act according to their own desires. They are slightly better than completely mindless slime mold spores, so they are Q1."

"It's a very complicated classification..."

Xia Xiaochi, who was studying seriously, followed suit and finished writing the last stroke.

If the biological level of mutant species was simply 0-100, it would be much simpler.

I didn’t expect that there are three dimensions, each with its own characteristics.

But...this division also has its advantages.

Next, you only need to know the biological level of the corresponding species, and you can quickly determine their characteristics based on the level index.

"It's not complicated actually," Shi Yi said as he peeled a candy and put it in his mouth.

"Even I don't often use the E and Q values. GP is the most important... The genetic pollution index directly determines the degree of abnormality."

After hearing this, Xia Xiaochi nodded and took notes carefully.

"You just said... the genetic purity of the gray mouse is 99.8%?" Xia Xiaochi asked.

Shi Yi brushed her short hair and nodded, "Yes, the genetic pollution level of the gray rat is only 0.2."

"Just 0.2 can make them become like that? Their original appearance should be only the size of a palm, right?!" Xia Xiaochi said in surprise.
