This cannot be considered a mistake.

Everyone experiences birth, old age, sickness and death, and viruses are no different. From birth to death, there are great changes in the organs of the body. But Sibo didn't understand: why would it be so much easier to conduct research with the freshly obtained samples than it had been at the new Beijing base?

The difference is too great. From the characteristics of the virus to the cellular changes of the infected target, the two samples are like coming from two planets. At the time of the new Beijing, Sibo only had ordinary "B" level permissions. All research on virus samples can only be carried out in a common experimental area, and cannot be carried to a personal laboratory for further analysis. Despite this, the virus data of the samples at that time was memorized by Sibo. Comparing before and after, he was surprised to find that the living samples obtained so far were very different, and it was simply something else.

Things are a bit of a coincidence.

Through Su Hailong's relationship, when Sibo was "gotten" from the new Beijing base, the virus crisis broke out in full force. During that time, Skber spent time in cars and airplanes. He simply didn't have the time and opportunity to go out, and there was no way that the soldiers accompanying him would turn the door to hunt down the walking corpse for him to get a sample. As for the research work, everything will not start until after arriving at the Northwest Base. At that time, the situation was very chaotic, the northwest region was vast and sparsely populated, Su Hailong was busy gathering the remnants, and various affairs of the base also needed to be straightened out.

Spiro himself is also responsible———— he has always believed that the characteristics of the virus will not change, and has always used the relevant data brought out by the new Beijing base as the basis for research. This situation lasted for more than two months, and it was only later that Spiro made a request for research equipment. Su Hailong sent people to search between several military bases and cities, which delayed for another part of the time...... In short, before coming into contact with these living samples sent by Liu Tianming's team, Sibo never thought that there would be any difference.

"The foundation of my research is based on existing living samples. In other words, based on the current living corpse samples, I am sure that I will be able to create an immunity agent in less than ten days. ”

Regardless of whether Tian Guangyao understood what he wanted to say, Sibo said the point of the problem: "This medicine is only effective for the living samples handed in by Liu Tianming and them. If it's the kind of virus that the new Beijing base is studying, I don't think it's going to be very useful. ”

"You mean, these are two completely different viruses?" Tian Guangyao asked uncertainly.

Sibo's face showed an extremely rare solemnity: "Perhaps, we have made a mistake in the direction of research from the beginning. I'm talking about the new Beijing base. I don't know exactly where they got the virus samples, but as things stand, the difference is really big. ”

Spiro is not arbitrary. He did not directly deny the research results of the new Beijing base, but only speculated in vague words. After all, a lot of things are not as simple as they seem. Especially at a time like this, there is no point in arguing about what is right and which is wrong.

Tian Guangyao was thinking about the same question.

Viruses and immune agents, two things are important. If it had been a few hours earlier, Sibo's inference would have been placed on the desk of General Su Hailong, the commander of the Northwest Base, in the form of a document. It's too late to say anything. Su Hailong's life and death are uncertain now, and the base is also in chaos. Even himself and Sibo were trapped in an underground shelter.

The word "out" is very simple to say, but it is very difficult to do in practice.

When Sibo didn't say anything about the development process of the immune agent, Tian Guangyao was just thinking about controlling the scale and intensity of the battle, and on the premise of trying not to attract the attention of the giant flying insects outside, get some food back and rescue more people from the base.

Now the situation is completely different. If Sibo could really create an immunity agent in ten days, things would have gone in a very different direction. The horror of viruses and giant insects are two different concepts. The former will turn humans into monsters, while the latter, although they feed on humans, will not parasitize, causing infection and mutation.

Even a death threat can be lifted. Based on this alone, Tian Guangyao felt that he had a reason to kill.

In the chaos, Tian Guangyao never counted the number of people who fled into the underground shelter. He stood up, pointed to the head and nodded: plus Su Hailong, the base commander who was seriously injured and unconscious, there were fifty-five in total. Removing the severed limbs, bleeding too much, and the men who had to stay behind to take care of them, there were thirty-seven more capable of fighting.

The shelter was stocked with a large number of weapons, and there was no shortage of ammunition. Aside from drinking water and electricity, this is by far the best news.

"I'll try to make sure the passage between here and the lab is as safe as possible."

Tian Guangyao returned to Sibo's side, lowered his voice, and said seriously: "We are not without opportunities. Listen to me, your lab is located right next to the mechanical repair shop. There is a set of automated air defense equipment, which was an experimental device that NORINCO brought in to test before the outbreak of the virus. ”

Sibo felt the fluid flow in his veins accelerating: "You mean, you can use that automatic air defense system to deal with bugs?" ”

Tian Guangyao nodded: "There are a total of sixteen four-pack multi-barreled cannons, and the reserve ammunition for one base is as much as 50,000 rounds. The system was supposed to be shipped to the southern test site, but then the virus broke out and things were delayed. The base was understaffed, and General Su ordered the system to be installed in several important locations. The mechanical maintenance workshop was assigned four cannons. If we're lucky, we'll be able to follow the passage all the way to the lab. Be careful not to get separated. You follow us, and I'll kill all the bugs that stand in your way and turn them into the most disgusting in the world. ”

Sibo was eager to try: "Let's do it now?" ”

"You have to be mentally prepared."

Tian Guangyao advised: "It's best to bring as much water as possible." You'll have to take care of the food, too. Also, as soon as you enter the lab, you close the passage. You're the only one in there, and the short-range communicator should work. Anyway, I'll be out there to help you keep those bed bugs at bay. ”

Sibo glanced at him: "A week? ”

"Ten days."

Tian Guangyao followed the time-limited standard that Sibo had said before. He viciously threatened, "If you don't get the immunity potion out by then, I'll throw you to those bugs and let you ferment in their stomachs." ”

Sibo smiled: "Don't worry! We're going to win this battle for sure. They're nothing. Don't forget, we are human beings and have a much higher evolutionary level than they are. Otherwise, the master who rules the whole world will turn into a bug. ”

After a few minutes, the people were ready to line up in attack formation on either side of the huge round-arched gates.

This is a floodgate controlled by the power system. In order to prevent a possible crisis, Tian Guangyao dragged two heavy machine guns from the underground warehouse and placed them near the gate, where they were operated by several soldiers who were not too seriously injured, and the thick black muzzle of the gun was pointed at the gate.

Under the watchful gaze of the people, the circular steel gate parted little by little towards the two sides. Although it was less than half a minute, people felt that time was extremely slow, and the fear and heaviness that were firmly suppressed in their hearts gradually increased.

The floodgates finally opened.

The arched circular passage was empty, and there was not a single figure in sight.

No bugs.

Reinforced concrete and alloy floors and walls were splattered with blood. There were countless messy red footprints left on the ground. It was left behind when people fled to shelters. Trails of blood stretch from the corner of the passage in the distance, connecting the space inside and outside the separated steel gates, recalling the scene full of death and gore in people's minds.

Although he had some doubts, Tian Guangyao did not take it lightly. He walked ahead with a grenade launcher in his hand, followed closely by several heavily armed soldiers. There is not much space in the passage, and four or five people can just form a suppression team with rapid firepower. According to Tian Guangyao's previous arrangement, the distance between the front and rear of such an attack team was about thirty meters. In this way, people covered each other and slowly walked out of the passage with bated breath.

Along the straight slope, Tian Guangyao walked all the way out of the underground shelter.

Heavy dark clouds were dispersing, and a pale blue appeared in the sky.

The empty base looked chaotic. The wreckage of the plane at the airfield in the distance was so striking that more than a dozen military vehicles were flipped on their side. Some had exploded, and the flames were mixed with black smoke, like giant pythons, stretching and shrinking towards the sky, spitting snake letters. Fragments from the explosion were everywhere, and broken glass flew from somewhere, reflecting an eerie dazzling light on the ground.

There were no bodies, and no wounded were to be seen. Except for the "hula-la" sound in the wind amid the flames and mechanical wreckage, the entire base was silent.

Sibo stepped forward from behind, holding an assault rifle. He stopped more than ten meters in front of Tian Guangyao, bent down, picked up something from the ground, and looked at it carefully.

Tian Guangyao did not let his guard down. He maintained a tense state of muscles ready to attack, and quickly ran to Sibo's side: "What did you find?" ”

Sibo spread his right hand: "This is what they left behind." ”

In the palm of his hand, a brownish-black fragment lay down.

Very hard, about three millimeters thick. The surface is covered with dense fine lines. They are distributed in a regular manner, feeling like blood vessels marked in red on a schematic diagram of the human body in a medical book, but with a larger gap. These fine lines are slightly lighter in color than the fragments themselves. The pieces give a hard and brittle feeling.

This is the body fragment left behind by a giant insect. A bullet is not fatal to them, but it can leave something behind them. This piece is supposed to come from their wings, or some other part of their body.

The expression on Sibo's face was very dazed, and he stood there and muttered, "Where did these bugs come from?" Why are they leaving? "To find this site, please search for "6 Mao" or enter the URL:.
