The whole city is my old attack

"This is your current situation where the whole city is infected by [ghost virus]."

In the car, the system elf projected a light screen, and was analyzing the current situation with Chu Feng and the others. On the screen was a map of the city's virus infection risk made by it, and the high-risk areas were in critical red:

"First of all, the hospital in Xicheng was the starting point of the virus outbreak, and then we found that the ghost attacking Lin Lan in the hospital was 7-year-old Xie Shiyu, indicating that the red-bellied mosquito flew into the elementary school next to the hospital and bit at least A little Xie."

Chu Feng looked at the risk map of the whole city, and the entire elementary school area was also marked red.

System Elf: "The role in primary school is Xie Shiyu, who is 7-12 years old. Among them, 50% of primary school Xiao Xie goes home to sleep at night, and the other 50% of primary school Xiao Xie boards at school. After being bitten, Xiao Xie carries [ghost shadow Virus], first of all, it is transmitted to the characters who are boarding at the school. This is also unfortunate, and the 50% who go home to sleep are still safe.”

In Chu Feng's memory, when he was in elementary school, he played with Xie Shiyu not only at school, but also near his home.So 50% of primary school Xiaoxie returned to the residential building.The residential building and the elementary school campus are separated by three blocks, and are currently in the yellow medium-risk area.

"There is another very bad news to tell you, master."

The system elf hovered in front of the light screen, pointing at Dongcheng with his dumb hair: "Because the virus first broke out from the hospital in Xicheng, and Dr. Xie's combat power in Xicheng was shown to be infinite, we all guessed that he would be the main body, so I think the East Side is definitely safer. But—"

The little elf pointed to Dongcheng, No. 25 Fenghua Road. This point was marked in very dangerous red:

"This is the only store in the city that currently has purple eustoma flowers. The doctor went here to buy flowers tonight."

Next to this flower shop is Dongcheng Junior High School, where Xiao Xie, who is 13-15 years old, is there.

System elf: "I checked the traces of the boss of this flower shop, Xie. After he got in touch with Dr. Xie, he went to the junior high school to deliver flowers. The school is currently organizing a school celebration."

The entire junior high school is red and becomes a high-risk area.Chu Feng frowned slightly. The next door to this junior high school is the high school.

Xiao Xie, who is the weakest in the kindergarten, is currently placed in the dormitory of the high school.

"Is there any risk of infection in high school?" Chu Feng asked.

"It's hard to say, because we don't know where [the main body] is now. The main body that was most suspected before was Dr. Xie. It turned out that he was not, and the main body was someone else."

The system elf clicks on the screen, and the mouse turns into a dark blood-red paint bucket, which is poured in the middle of the high school:

"[Ghost virus] is centered on [the main body], and spreads like a spider web, very fast. Assuming that the [main body] is in the high school, the area where the [main body] is located will become the most severely infected area."

Click [Undo] on the system elf, and the high and middle parts will return to the original yellow-medium risk, the elf:

"So our task is still: do everything possible to find out [the main body]! Dear little master, do you have any doubts about who is the main body?"

Chu Feng was silent, Xiaoba Xie in high school and President Xie in the commercial street should not have low combat power.But... can it really be taller than Dr. Xie?

"I'm not sure." Chu Feng said.

If they rashly decide who is the main body this time, it will waste a lot of time and energy, and it will delay the progress even more.

"I have a question." Lin Lan raised her hand, "If, I mean, if Xie Xiaoba is the most powerful person in the city and is the main body, how did the virus spread? The virus first broke out from Xicheng Hospital At that time, Dr. Xie probably hadn't bought flowers yet, that is to say, the entire East City should be safe. How did Xie Xiaoba get infected with the virus?"

"If Xie Xiaoba is the main body, then he may have been infected from the very beginning."

The system pulls up a document [Reversal Conjecture of Ghosting Virus Transmission Mode and Its Deconstruction Method], and zooms in on a transmission diagram in the document:

"Ghost virus is a game virus, which is different from the virus in reality. Although we all look like people in the game, we have no biological structure in essence. Everyone is code. Including all the buildings and streets in your dream city , scenery, are actually data codes.”

The code analysis diagram of Chu Feng's dream city appeared on the light screen, each building street, each transparent stickman, all floating in the body with rows of ice blue digital code sequences.The system elf explained:

"In the beginning, a red-bellied mosquito carried a line of [ghost virus] code and bit your little Xie in the kindergarten."

The light screen is showing a dynamic slideshow, a line of red [ghost virus] code, entering the body of a particularly small transparent stickman...

"This string of virus codes has entered the data sequence of kindergarten Xiaoxie, and Xiaoxie is in your Dream City database, so it is equivalent to this line of virus codes invading your Dream City's general database. It will quickly remove all data Find the character with the strongest combat power in the code, copy an electrical signal, and send it over—"

On the light screen, the red [Ghost Virus] code instantly turned into two, one stayed in Xiaoxie's body in the kindergarten, and the other flew out and flew into the [Main Body] with the highest combat power.

System elf: "The propagation speed of electromagnetic waves is the speed of light. That is to say, at the moment when Xiao Xie in the kindergarten was bitten, the copied virus electric signal was sent out, and a certain character with the highest combat power in your city immediately got sick. Now, it becomes the [body] of the virus. Fortunately, this virus only emits electrical signals to spread at the speed of light when it is looking for the body to parasitize. When it infects other characters, it is not the speed of light, nor is it 100% infected .”

The system elf continued to demonstrate on the light screen. The data sequence of the kindergarten Xiaoxie with the virus code in his body was disordered at first, and then gradually adjusted. This string of red codes was thrown out of the body——

"The character's own data sequence has a certain degree of exclusivity, just like the immune system of a real human body, which can spontaneously eliminate abnormal data sequences. Because you rescued Xie from the fire in the kindergarten, the possibility of being killed has dropped to 1%, so the immune system in his body The data immunity has been improved, and after being infected by the virus code, it will spontaneously expel this string of abnormal sequences."

——So even though Xiao Xie from the kindergarten was bitten, she didn't get sick.

System elf: "However, after the fire, you sent Xiao Xie from the kindergarten to the hospital for treatment, so this string of virus codes was passed on to Dr. Xie, and then passed on to others by Dr. Xie, continuously adding value. Since Dr. Xie is not the main body, you In a certain place in Dream City, there is another [ontology], who is continuously spreading this virus to the characters around [ontology]."

"The current situation is almost like this." The system elf in front of the light screen looks like a little teacher, and the bristling hair on his head looks like a pointer. "Do you have any questions?"

Chu Feng: "This game virus is infecting the data sequences in my city?"

System: "Yes."

Chu Feng: "So non-character data sequences, such as streets and buildings, may be infected?"

"Yes." The system elf said, "Do you remember that when you first entered the hospital, you found that the lights on the first floor were broken, flickering like ghost movies, and the second and third floors were all in darkness. Then It is the consequence of the building sequence being infected, and the building will become a little... abnormal."

Lin Lan: "Based on this, other non-character [creatures] in the city may also be infected? For example, cats, dogs, and birds."

System: "Yes. Animals will also become... more abnormal like the building sequence. The specific aspect of the abnormality depends on the specific data sequence."

"I understand!" Lin Lan suddenly realized, and shouted, "We have always fallen into a misunderstanding, thinking that the character with the highest combat power must be a certain character. In fact, is it possible that the top combat power is [animal], such as an animal? cat!"

The black system elf drooped speechlessly: "That's it, if my master raises Mancheng [Lin Lan], with your level of combat power of 5, I would indeed suggest that my master turn his attention to searching for the cats in the city." Cats and dogs, because you may indeed not be able to beat a cat. But since my master raises [Xie Shiyu]... you know."

Lin Lan: "...Thank you, I was offended."

Chu Feng: "Is it possible that the main body is [building]?"

"Impossible." The system elf said: "[Ghost virus] needs active data flow to add value, and the best host is a living thing. It may invade the data sequence of [building], but it will never Take the [building] as the body. Therefore, the [body] is still the most powerful character [Xie Shiyu] in your dream city. Please don’t be disturbed by other thoughts, the most important thing for us is to grasp the [body]!"

X: "Can this virus infect players?"

——Chu Feng had come into contact with Xiao Xie from the kindergarten who was bitten by mosquitoes, and Dr. Xie who was infected.

System elf: "It's possible, but the possibility is low. Just in case, my defense code is just finished! I'll eat it for my dear little master later."

Lin Lan: "What about me? What should I do? I came to the hospital to tell fairy tales to brother Xie, and then I was bitten by a mosquito!"

The unlucky Lin Lan was infected with [Ghost Shadow Virus], and ghost shadow Lin Lan appeared. The water gun Xiaoyu fell off the cliff with the ghost shadow and died together. Chu Feng changed his choice with regret medicine, and killed ghost shadow Lin Lan in the hospital.But the [ghost virus] on Lin Lan's body was not removed.

System elf: "I am very sympathetic to your experience, but there is no other way. Those who are infected have to accept their fate. When you start to have dizziness, nausea and other adverse symptoms, you will pop out of [Dream City], and you will be fine when you return to reality. !"

Lin Lan: "..."

Chu Feng: "Can this defense code be given to all the characters in the city?"

"I'm sorry I can't. If I could do this, I would have done it a long time ago." The system elf took out a green capsule of defense code and handed it to Chu Feng:

"The player sequence is different from the character sequence. Your player sequence is open, because you often come in and out of the game, so I can implant defense codes. The character sequence is fully closed, and there is no way to implant defense codes. Think To get rid of the virus, we can only find [the main body].”

Chu Feng ate the green capsule of the defense code, and glanced at the X beside him:

"What about him?"

X was a little surprised that player Chu Feng would care about him.

"I'm fine," he said.

System: "The regulator's data sequence is the most unbreakable! Viruses will not infect the regulator, please rest assured, the game company and the regulator center will always protect your safety!"

Chu Feng: "..."

System: "Do you have any special doubts about which Xiaoxie has a particularly high combat power? Any clues are fine."

"He was in high school." Chu Feng said, "During his time in high school... he didn't have a good life."

"High school." The system circled the key points of Dongcheng High School on the map: "Is there any more? Combat power is linked to the mental power of the host. It doesn't have to be older, and it may be younger."

Chu Feng thought for a while, then shook his head.When Xie Shiyu was young, Chu Feng was also a little Chu Feng, and his observation skills were not as sharp as when he was an adult. Moreover, his memory was too long, so he couldn't recall many details now.

System: "Then... let me conduct an extensive search and investigation first. Do you have any other ideas?"

X: "Can you find it through the combat power ranking?"

The main body of [Ghost Virus] is the character with the highest combat power. In order to cover up this ranking, the virus will encrypt the rankings of the characters with the highest combat power.

X: "The codes for those characters may have a few more characters than other characters."

The system elf raised the stupid hair on his head blusterily!

"Damn, why didn't I think of that!"

Chu Feng: ...

Lin Lan: "This is a good way! As expected of a master. System! Try it quickly."

The system elf beeped and tapped the code on the light screen for analysis: "This method is really good! Doctor Xie's character code does have one more encrypted character than other common characters!"

Lin Lan: "Quick, who is the multi-character character in the next code?"

"Don't rush me!" The system elf is processing a huge calculation program, "Master Dreaming City has a lot of data, and the actual screening will take some time. Moreover, the virus may confuse us, and the characters who do not have such high combat power , deliberately encrypted, making us mistake him for [Ontology].”

Lin Lan: "No matter what, it's better than looking for a needle in a haystack all over the city. First catch all the guys with extra characters in the code, these Xie brothers are all key suspects, and then we will catch a real [ Ontology]! Cousin, what do you think of this battle plan?"

Chu Feng: "Yes."

System elf: "Then leave it to me! I will analyze the city's data codes tonight, and try to draw up a list of [main body suspects] tomorrow morning!"

It's getting late tonight, it's almost time to quit the game.Lin Lan glanced at her cousin, then at God X sitting next to her, then at the ice sculpture Doctor Xie lying next to her...

Lin Lan thought, it would be better for him to withdraw from the gunpowder field first.

beep—

Lin Lan's brainwaves were disconnected.

The system elf closed his eyes and was quietly analyzing the data.

There was a gentle night breeze, and there was silence in the car.

Chu Feng was going to stay and spend the night with Dr. Xie. He froze Dr. Xie, and when he thawed it later, he didn't know how much mood he would lose. He needed to comfort him.

——But X hasn't left yet, Chu Feng is waiting for him to leave.

Tick, tick, time passed by.

X sat beside him like a statue, showing no intention of leaving.

Chu Feng finally couldn't help it, and coughed lightly:

"Aren't you... going back to rest?"

Anyone with a little social experience can tell that this is driving away customers.

X: "It's okay. I slept in during the day."

X seemed completely unable to understand the subtext of Chu Feng's chasing customers, and even asked him with an innocent face:

"Why don't you go back?"

Chu Feng: "..."

The system seems to have heard their conversation. The black elf opened his eyes and said purely:

"Oh! My master can't leave yet, I want to teach him to activate the defense code!"

Chu Feng: "Isn't this code enough to eat the capsule?"

"No, you still need to activate. Know the specific binding of target cell-receptor protein? Biological one. The mechanism of this defense code is similar to that. The defense code is like a specific protein, a piece of plasticine, it must You need to combine with the virus code first, mold this piece of 'defensive plasticine' into the shape of the virus code, the next time the virus invades your body, this piece of 'defensive plasticine' will rush up to combine with the virus code, and then Initiate the self-destruct sequence. That's the defense."

Chu Feng: "Speak simply."

System Elf: "To put it simply, it is the defense code in your body, which needs to be combined with the virus code first."

Chu Feng: "So?"

"Uh..." The elf looked at X, hesitated for a moment, and then looked at the master: "So, you need...to find an infected character and make...well, contact."

Chu Feng:?

System elf: "Okay, let me be straight, master, you can't leave tonight, you have to go to sleep with Dr. Xie."

——Complete the specific combination of codes and activate the defense effect.

X: ...

The night wind blows, bringing a bit of coolness.

Chu Feng turned his head and looked at X:

"Are you ready to go now?"
