The oldest in the village school is Huang Lei, although he is not the strongest, but he has somehow become the eldest brother of others, anyway, they all say that he feels quite safe by Huang Lei's side, he is quite honest and reliable, and he is a straight man, and he has no bad intentions.

So when the class meeting was held in the afternoon, the head teacher An Ruxue directly appointed Huang Lei as the class leader, which made him quite embarrassed, but no one else had any opinions, and the matter was settled.

After the class meeting, Gu Tao then started the class, and in this class, except for ten students, including the five golden flowers and An Ruxue, they all sat inside to listen, because they didn't know anything about the so-called firewall system, An Ruxue still heard of it, but the others were just blind.

"I'll answer the noon question first."

Gu Tao supported the podium with both hands, black jeans with a white shirt, a little old-fashioned but his temperament suddenly became taller, and he really looked like a teacher.

"Why do I say that if the Incheon gas incident happened to us, it would be put down within five minutes?"

The large and small students in the audience listened carefully and carefully, but saw that Gu Tao took out a fully open piece of paper at this time and hung it on the blackboard: "Lean forward a little, the words on it are a little small, you can't read clearly." ”

After the sound of tables and chairs moving, everyone sat around the podium, and then they saw that the entire city map of Incheon was densely drawn on this piece of paper, and it was also marked with pens of various colors.

Gu Tao picked up the whip and pointed to a red dot: "Let me tell you the whole process of the Incheon incident first. First, a truck was found at this point that had been left vacant on the side of the road, and the truck exploded with it. ”

He said of the explosion with a whip that circled the point representing the truck: "The initial explosion affected an area of 500 square meters, but soon these toxic substances began to volatilize, the area was about 1,700 square meters, and the wind direction at night was from west to east, two to three levels, and the maximum area of influence was six meters per second. And depending on the air temperature and pressure and the specific gravity of volatiles, it affects a height of up to 30 meters. That is, it is a circular area that moves at six meters per second and expands by thirty percent per minute. ”

"Although these substances are volatile, they are relatively stable, and only a very small amount can cause human poisoning, so people in this area can't escape." Gu Tao's whip pointed to the second layer of the city map, which was a circle drawn with a blue line, and the whole was about two square kilometers: "This area has the highest concentration, and it is too late to react. ”

"But what happened after that, because the South Korean side didn't have a corresponding emergency response system, they could only let these toxic substances spread everywhere with the direction of the wind, and soon half of the city was enveloped in it." Gu Tao pointed to the third, very large circle: "When we arrived here, there was already a riot in the city, and it continued to move westward with the direction of the wind, and soon spread to the whole city. ”

"But isn't everyone poisoned? Of course not, even in the end, the proportion of poisoned people is only 30 percent, but these 30 percent people are already nearly one million people. The maximum limit for the level of riot in a city is 8 percent. What do you mean? That is, a city of 10 million people, 800,000 people riot, then the city can be counted as falling. By this time, 12 percent of the population in Incheon had fallen into chaos. ”

"What is the state of the 12 percent? Zombie state, but I'm going to correct it, they are not zombies, they can be treated. But at that time, in the absence of an antidote, the 12 percent of the population who had rioted due to poisoning began to fall into a state of madness. Panic began to spread, and there were a large number of deaths, not only among ordinary people but also among the rioters. At this point, the South Korean military began to move, but it was too late, and in the absence of heavy firepower, hundreds of thousands of rioters and headless flight fugitives would smash any force to pieces. You'll all laugh at the fact that in this incident, of all the factors that led to death, the stampede was the number one, reaching a staggering 74 percent. ”

The students below didn't laugh, they just gasped, they thought that most of the deaths were weapons or the tearing of those infected, but they didn't expect that such a large percentage of them were trampled to death...... Seventy-four, that is, 600,000 people were trampled to death.

It's not quite what you think.

"Then came the fall of the city, but the rate of infection slowed down accordingly, as the virus ring moved into the suburbs and headed for Seoul. At this time, between Seoul and Incheon, the South Korean government began bombing the area, forcibly blowing away the poison ring with artificial strong convective weather. But by this time Inchon was finished, and the poisoners began to attack something they saw, and the whole city went into purgatory. When I was in the past, the only thing I could do was to gather the survivors, and the higher the building, the safer it was, because the poisoned people were not so smart, it was easy to get lost in the upper floors, and according to biological instinct, the poisoned people were not willing to climb the building to consume too much energy. Gu Tao pointed to some areas of the indication: "The proportion of survivors is still very large, they are either hiding at home or gathering together to resist and fight back and wait for rescue. ”

By the afternoon of the next day, the city had stabilized, large rescue teams were stationed in the city, and survivors and the dead and wounded were being helped and treated. From the incident to the end of the Red Alert, it was nineteen hours and seven minutes. In those 19 hours, more than 800,000 people died. ”

After Gu Tao explained the entire schematic diagram, he coughed and replaced it with a schematic diagram of SH: "This is one of the densely populated cities in the entire Chinese. If the Incheon incident had happened here, almost 30 percent of the people would have been affected without the firewall, and the exact number would have been 7.5 million, which would not have been less than the death rate in Incheon, depending on the size of the city. This would be an unprecedented catastrophe, a huge humanitarian catastrophe that would make the whole world tremble. ”

Then Gu Tao pointed to a red dot with a whip: "But we have a firewall system." For example, if we take this as the origin of the explosion, within seven seconds after its explosion, the drone arrives at the scene and begins to evaluate the explosion, analyze the water and air samples, and begin to inform the headquarters of the composition of the poison, the headquarters begins to assemble the antidote, and the prevention and control team will also be dispatched, and then a condensation bomb will explode in the air to project 400 million cubic meters of water down, forming short-term heavy precipitation, and the reloading will arrive in the form of an airdrop in about three minutes. Begin to contain the rioters and the second condensing bomb will carry a large amount of antidote, and then the prevention and control forces will arrive at the scene, conduct guidance and communication, and cooperate with heavy equipment to suppress the riot. When the third atomizing bomb is dropped, everyone on the scene will fall asleep indiscriminately, and this area will become a dead silence, and ordinary anti-chemical warfare troops will enter the battlefield and begin to clean up one by one. In this way, even in the most prosperous areas, the poisoning rate will be suppressed at 0.4 percent. But if you want to say whether there will be casualties, there will be, God can clear the customs without injury, but the red line of 5,000 people and more than 7 million people, this is a different concept. ”

Gu Tao continued: "This is the power of the firewall system, just like antivirus software, it may not have the ability to contain the invasion of viruses, but it can stifle viruses in the initial state before they cause serious consequences. In addition, the firewall system has a very significant feature, the denser its network, the stronger the capability. When every node is able to communicate with each other, it is at its most powerful, and it can even resist and predict any behavior that may bring disaster. That's an overview of the firewall system, is it strong? It's really terrifyingly strong, but do you say it's easy to build? It's really not easy. A large amount of energy, personnel, materials, and a long period of training, research and development, and sorting are not something that can be done by one or two people, but something that can only be completed with the cooperation of the entire human group. And do you know who built the first node of the human firewall? ”

An Ruxue thought for a while and shook her head silently: "Who is it?" ”

"The Gu Sect Master you have in mind." Gu Tao was cheeky and hehe: "He established the first, second, third and fourth nodes, counting Incheon, there are already four nodes." ”

"How many are there?" Chen Xing asked, holding her chin.

Gu Tao thought for a while: "Fourteen thousand four hundred and fifty-two." ”

“……”

“……”

“……”

It's a little bit more in quantity...... But after this incident, I am afraid that many places will take the initiative to ask for it, just like the South Korean authorities, and if the later effect is good, I am afraid that South Korea will agree to build more than one base after tasting the sweetness, which can be regarded as the first step to go abroad.

And Gu Tao also had something he didn't explain just now, that is, the firewall system is multi-compatible, from nuclear bombs to sword immortals, from demons to magicians, no one refuses. And judging from the simulated content, this model is the strongest and most efficient.

In the human world, this is known as the Firewall Project. And in the secret world, after Gu Tao thought hard for the past few days, he decided to set the name of the sect as the heavenly guard, which is handsome and stylish! When I went out, I heard that Kunlun was more than a criticism. And the crowd that participated in the discussion, not a single one did not agree, and they all felt that this name was bright and audible!
