Ancient Invasion [End Times]

The day after the invasion·“…the invasion has begun.”

"When are you going back to the compound?" Cheng Sheng looked at Duan Yi and asked casually.

"I won't go back for the time being. I have a mission." Duan Yi walked to the window of Cheng Sheng's office.

Looking outside, there is a large playground downstairs. Several classes of students are taking physical education classes, occupying most of the playground.

——This is less than one-tenth of the number of people in this school.

Duan Yi looked at the students outside the window and said, "If an outbreak occurs, such a school, with such a dense population, will become the first difficult city."

"If it breaks out, there will be no difference between the first, second, and countless troubled cities." Cheng Sheng maneuvered the wheelchair to slide to Duan Yi's side, looked out the window with him, and said.

Duan Yi wanted to say something, but the communicator on his waist issued a warning of emergency martial law.

A screeching horn means nothing good is going on.

Duan Yi glanced at the digital code display on the top, and quickly connected to the communication device: "897493 code name Deathstroke, please instruct."

"At the Himalaya base, an unknown creature was found approaching yesterday and was killed. You need to identify these people."

Duan Yi frowned: "Yes."

The scene replay of the scene was projected on the communication screen——

Four people wearing snow military uniforms appeared in the distance of the Himalayan military research base.

The speed at which they moved was increasing at a speed visible to the naked eye, as if they had adapted to this environment.

The sentry at the gate fired a warning shot and asked the four people who were approaching quickly to report their ID codes and mission codes, but no one responded.

——Those four people rushed forward with bare hands!

Their skills are still a little stiff, but they can be seen to have a tacit understanding, and their movements are crisp and sharp, pointing at the vital points.

The soldier on guard panicked for a moment, and subconsciously raised his hand to block, but he didn't expect that the extremely thick protective clothing and the large piece of flesh on his arm were torn off by one of them.

The soldier let out a scream, and hastily fired his guns in defense. Seeing this, the surrounding sentries responded quickly and fired their guns as cover.

Those four people were shot several times in a row, which is enough to kill an ordinary person, but they were not affected at all, and they did not show any intention of stopping the attack.

Four people swarmed up to the wounded soldier. Amidst the gunshots and flames, only the sound of biting and chewing could be heard mixed with the soldier's screams, which gradually faded away.

Cheng Sheng looked at the scene in the projection, his breathing was a little rough, and his palms were cold.

In the projection, the four people raised their heads from the soldier. All four faces were covered with blood and flesh without exception. There was even a sentry around him who couldn't bear it and bent over and retched.

"Stand up! Take your gun to defend! Keep an eye on your target! Damn it!" Cheng Sheng heard someone shouting in the video, followed by a series of screams and screams.

The scene became more and more chaotic, and panic, uneasiness, and despair spread outside the base——

"Guns are useless!"

"It can't be killed at all!"

"God, what kind of monster is this..."

"what should we do!"

The surviving sentinels began to retreat towards the gate of the base, but they did not expect the gate to be closed—they were left outside.

Cheng Sheng clenched his fists. This move was expected—a large number of viruses and biochemicals were stored in the research base, and the risk of a small gun fight was unacceptable—but it was still unacceptable.

At the same time, Cheng Sheng felt a rush of vigor and danger suddenly surged from his side, which made the hairs on the back of his neck stand on end.

He looked over subconsciously, and saw Duan Yi staring at the screen with a cold face, his jaw and muscles tensed, like a wild beast ready to go, making people feel unparalleled danger.

The sentinels who were locked outside the base gate began to despair. The bullets seemed to only stop and hinder the movements of the four people, but could not essentially stop their attack.

It wasn't until the heads of the four people were blown apart by the gun that they fell down. All the surviving sentries were scratched and bitten to pieces.

The gate of the base opened slowly, and someone rushed out carrying a stretcher from inside, and carried back the few surviving sentries.

The video was finally fixed on the camouflage uniforms of the four people, their code numbers were embroidered on the chests, and some of them fell out of the silver necklaces in their necks, and the numbers engraved on them were also consistent with the numbers on the camouflage uniforms.

"Colonel Duan Yi, are these your soldiers?" An impersonal question came from the cold communicator.

Duan Yi looked away from the screen, took a deep breath of cold air, and replied coldly: "Yes."

"Find out exactly why they're the way they are."

"Yes."

"Disband."

"Wait a minute, major general, I want to ask, can their bodies be transported back?" Duan Yi said.

"Dismissed, Colonel. We need anatomical analysis."

"Yes."

Communication hangs up.

Duan Yi clenched his fists, his face darkened, one side was his own soldiers, the other side was orders and the overall situation.

"Duan Yi, how long has it been since those four people disappeared?" Cheng Sheng seemed to have withdrawn from the emotion in the video, he asked calmly, while operating the wheelchair to slide to a whiteboard, he started with a marker pen in his hand. calculate.

Duan Yi took a deep breath, calmed down, and walked to Cheng Sheng's side: "Four days."

He watched Cheng Sheng write equations and calculation rules that he couldn't understand on the whiteboard, paused and added: "It's been three days since the heartbeat appeared."

Cheng Sheng nodded: "The iron box of their mission did not appear in the video - I hope it was just lost - but assuming that there was a problem with the iron box that caused the four of them to become what they are now, then the four of them are typical The virus-infected person is also the only one who used to be a live carrier."

Cheng Sheng's eyes turned to Duan Yi, and the very familiar eagerness that was often seen in the research compound flashed in his eyes.

He muttered to himself: "If only those four people were in my hands..."

He will use the fastest speed to test, isolate diseased strains, research...

"Doctor." Duan Yi interrupted Cheng Sheng and reminded.

Cheng Sheng clicked his tongue regretfully, then returned to his senses and continued to explain what he was writing now——

"RO, the basic reproduction number, means how many healthy people an infected person will spread to. Among them, R means the speed at which the virus reproduces. The larger the R, the more aggressive the resistance and measures we need to do. "

Cheng Sheng wrote dense blackboard writing on the whiteboard quickly, and at the same time gave examples to Duan Yi, like a few treasures, speaking at a fast speed:

"During the 17th and 18th centuries, smallpox was prevalent in Europe, and the death toll reached 6 million. Historians at the time fearfully called it the accomplice of death, but the basic infection number of smallpox was only 3."

"Further ahead, the Black Death, which was prevalent in the 14th century, ran rampant for three centuries, killing one-third of the European population at that time. Its basic infection number was 4-6."

Cheng Sheng was writing on the blackboard while remembering, and unconsciously tapped on the armrest of the wheelchair with the other hand, his emotions seemed to become inexplicably high.

"Before, when I was conducting infection simulations in the biological laboratory, the basic infection number of the virus we discovered under the glacier was estimated at..."

He quickly calculated: "...more than 7. Every time this number increases by one point, the risk and the scope of infection will increase exponentially."

The more dangerous things bring people fear, but also excitement.

"Of course, this value is affected by many factors. Just the cultivation and simulation calculation in a laboratory does not mean anything, but it is enough to sound the alarm for everyone."

He paused, with a bit of sarcasm in his words: "If they believe me."

To use the words of other people at that meeting who refuted him, it is—instead of listening to a young Ph.D. who studies paleontological viruses on the prediction of future epidemic development trends, it is better to listen to what real experienced experts say. Said.

"If your subordinates are infected with the virus in the box, if the few surviving sentries are also infected due to blood, scratches or air... various factors, then the speed at which the Himalayan base is completely infected Only two days at most."

Duan Yi frowned. What Cheng Sheng said almost required the entire base to be evacuated or abandoned. This was impossible, not to mention that it was originally a biological research base.

"They have their own professional research team, and they know how to isolate the virus," Duan Yi said.

"They must do the highest degree of isolation." Cheng Sheng emphasized the word "highest", couldn't help but raise his voice, and pointed to the disappearing projection screen, "However, in the video just now, those who came out to lift The person on the stretcher didn't even wear any isolation suits or protective goggles."

"If they only have such a sense of protection in BSL-4, then the virus will leak out sooner or later—sticking to their leather shoes, sticking to their coats..." Cheng Sheng took a deep breath, lowered his voice, but It also brings a kind of creepy chill.

Duan Yi frowned when he heard the words. He didn't understand the spread of viruses, but he believed in Cheng Sheng.

He took a deep look at Cheng Sheng, quickly contacted the base, and made a video call: "Major General, 897493 is codenamed Deathstroke."

Cheng Sheng actually didn't expect to be able to persuade Duan Yi so easily.

After all, a soldier of Duan Yi's level knows very well that without any substantial evidence, he cannot issue a warning.This kind of rules and regulations, like obeying instructions, should be engraved in the blood.

Cheng Sheng squinted his eyes, like a cat whose fur has been smoothed out.

"Report the situation, Colonel." The major general at the other end of the video said.

"According to our doctor's analysis of the research virus here, the base needs to adopt the highest isolation measures." Duan Yi said.

"We have taken..."

Cheng Sheng cut off the other party's words: "Not only those four corpses, but also those sentinels."

The major general on the opposite side suddenly lowered his face: "Colonel, who is this? Our call must be kept strictly confidential..."

"He is Dr. Cheng Sheng, a Ph.D. in the study of paleontological viruses..."

"Secret your call." Just as Duan Yi opened his mouth to explain, Cheng Sheng's impatience reached the extreme.

The face of the major general on the opposite side became a little exciting in an instant.

Cheng Sheng ordered very forcefully, "Listen well, not only the laboratory for autopsy needs the highest security isolation measures, but also the few sentries who survived the injury and all the healthy soldiers who have come into contact with them need to be isolated separately , Avoid appearing in crowded restaurants, training camps and other places.”

"What did you say?" The major general frowned. "Are you implying it's contagious?"

"I'm making it clear that this is a high infection." Cheng Sheng cursed in a low voice, "Now, immediately, do as I say."

"Wait, what basis do you have?" The major general asked, "It is impossible for us to do such a useless and labor-intensive isolation because of a hypothesis that is not supported by data..."

Before he finished speaking, the door behind the major general was roughly pushed open, and a soldier's panicked face appeared in the video: "Major general! The base has been attacked!"

"What?!" The major general turned his head sharply, "Who was attacked?"

He had just finished asking when a face quietly appeared behind the young soldier.

There were still visible, blackened scratches on that face—one of the Sentinels who survived that day.

Before the major general had time to remind the soldier, the sentry grabbed the soldier by the neck.

The sentinel's fingernails seemed to have undergone some kind of mutation, becoming long and sharp. With just one click, they easily cut open the young soldier's throat and blood vessels, and blood spattered on the major general's face without warning.

The young soldier's eyes were wide open, blood was foaming from his mouth, and he tried to speak but couldn't utter a word.

The major general took a deep breath, and he looked over the door. It wasn't just his side that had this situation—the outbreak seemed to happen only in a flash, and the entire base was already in turmoil.

He hastily picked up his gun and rushed out.

The communicator is still on.

Through the connected video communication, Duan Yi and Cheng Sheng saw those bloody and primitive killings in their entirety.

Gunshots, screams, and cries for help rang out.

"...The invasion has already begun." Cheng Sheng took a deep breath, and said to himself, "What you see now is the latest virus, Pandora."
