The special forces in the base rushed out, and the soldiers at the head held bulletproof shields and quickly laid out a copper wall. Pen? Interesting? Pavilion wWw. ｂiquge。 The special forces behind the info opened fire on the car at the door.

The killers of the Reaper organization are all outlaws, although the plan to crash into it failed, and all four members of the lead car died, but they were not frightened by death, jumped out of the car with guns, and engaged in a fierce exchange of fire with the special forces.

Liu Yi and Su Anqu retreated to safety with the help of their comrades-in-arms, and the two hated these people who dared to attack, so they picked up their guns and joined the battle.

Taking advantage of the firefight, the two killers took out two grenade-sized objects not far from the feed mill, lifted the drainage manhole cover, and threw the things in.

As soon as the two grenade-sized objects were thrown in, they exploded, bursting into puffs of smoke with a faint fruity scent.

Below this manhole cover is not an ordinary sewer, but a ventilation hole in the underground research institute. The smoke quickly cleared, and the colorless gas dispersed through the central air conditioner under the vent towards the underground research facility.

Some of the researchers in the underground research institute panicked, and some didn't care at all, and continued to study, and all beings were in a different state. Even if the researcher was terrified, he knew that no one would be able to break through the underground research institute, and everyone would be able to keep their composure. Another alarm sounded in the underground research institute and all air conditioning systems were automatically turned off. The researcher's face finally changed!

Several researchers in the air-conditioned room smelled the smell of fruit and wondered who had eaten it! Then he immediately foamed at the mouth, and his body fell down with convulsions.

The military researcher at the underground research institute exclaimed: "Sarin gas, everyone don't breathe, leave immediately." ”

The gas alarm in the air-conditioning system was automatically turned on long ago, and while the air-conditioning system was closed, the poison gas was pumped to the pre-planned place of the building. Fortunately, this underground structure was originally built in accordance with the three standards of defense against nuclear attack, biological weapons, and chemical weapons. In the event of a chemical weapon, an alarm will be automatically issued and emergency treatment will be carried out.

Gas masks were available in the research room, and researchers picked them up, put them on, and ran. But even so, some people still fell to the ground after putting on gas masks, foaming at the mouth, blurred vision, and having difficulty breathing.

The doctor took atropine from the pharmacy, put on a gas mask and hazmat suit, and ran quickly to the research room. As long as atropine is injected and artificial respiration is performed, the poisoned person can be rescued within a few minutes and death can be avoided.

But when he ran to the research room, he found that several of the researchers who had fallen to the ground were dead, and the people wearing gas masks were all convulsive before they died. He hurriedly injected atropine into it, but it was of no avail, and atropine could not prevent the researcher's death.

This is not sarin, it is definitely not sarin gas.

The scientific name of sarin is isopropyl methofronate, which can paralyze the central nervous system of a person. It is a commonly used military agent and is classified as a nerve agent according to its nociceptive effect. During World War II, it was named "Nova VI". It can invade the human body through the respiratory tract or skin and mucous membranes, and is extremely lethal, even if a small amount is inhaled within a few minutes, it can be fatal.

However, sarin gas can be treated with atropine and oxime, although the gas may cause damage to nerves, brain and liver afterwards, but at least it can save life. But now atropine is ineffective, indicating that the poison gas is not sarin, but a more violent poison gas - Soman.

Soman is a colorless liquid with a faint fruity aroma, medium volatility, and its chemical name is isoethyl mefluorophosphate. Pure soman is a colorless liquid with a faint fruity aroma. Soluble in water and soluble in organic solvents. It can penetrate the skin and rubber products, and is easily adsorbed by porous substances. Inhalation toxicity is 2-4 times greater than sarin, and skin toxicity is 5-10 times greater than sarin. Its outstanding advantage is that the volatility is moderate, not only the primary cloud can easily reach lethal concentration, but it can be poisoned in just one minute. Regenerated clouds can also achieve a certain amount of damage, and will die after 20 minutes of exposure. Its most significant feature is that it is quick to poison and has no specific drug, so it is known as the most difficult poison to prevent.

Not to mention that chemical weapons are strictly prohibited by international organizations, even poison gas like Soman is definitely not something that ordinary terrorist organizations can obtain.

After all, sarin is a poison gas that is still easy to handle, after all, it was researched during World War II, and many countries were in turmoil, and a large number of chemical weapons were lost and flowed into the black market. For example, on March 20, 1995, Aum Shinrikyo released sarin gas on the camp subway in Tokyo, Japan, in the morning. The terrorist attackers released sarin gas on five trains on the third subway line, killing 13 people, poisoning nearly 6,000 people, and hospitalizing 1,036 people with serious injuries. On the day of the incident, several main subway lines around the seat of the Japanese government and the Diet were forced to close, affecting 26 subway stations and plunging traffic in Tokyo.

Thinking that sarin is so powerful, and other countries have stricter control of poison gas, it would be a joke if Soman could flow out again.

The doctors at the underground research institute were helpless against Soman's poison gas, because there was no special medicine, they were not prepared at all, and could only watch the researcher be tortured to death by the poison gas.

Fortunately, the air conditioning system automatically alarmed and automatically discharged the poison gas, otherwise, all the people in the underground research institute would have been poisoned by the poison gas, and none of them would have survived.

The researchers ran in panic, trying to run to the surface to avoid the threat of poison gas. They wore gas masks, still fearing that the gas would penetrate deep into their skin and lead a horrible death.

When the special forces on the ground heard what was happening underground, the whole small universe exploded. It's absolutely unbearable for these guys to kill the scientists they protect.

The killers rely on cars, and the special forces rely on shields, from the beginning of the two sides do not back down, to the current hole cards. The killer wants to enter the underground base and take out heavy weapons such as bazookas again, but the special forces are more powerful, and they have a large number of sniper rifles to kill people with bazookas.

In the face of sniper rifles, the killers simply did not dare to show their heads, and showing their heads was a death. And the special forces did not let them go because of this, and moved out two QLZ87 type 35mm automatic grenade launchers. Paired with armor-piercing anti-personnel shells, three cars and more than a dozen killers were sent to heaven in an instant.

This time, the killers couldn't stand it. They didn't have to wait for the support to come, they quickly drove away, and if they didn't run, their lives would have to be confessed here.

The special forces don't plan to let them go, whatever, run away after the fight, when this is the game hall! Several names of the underground research institute cannot be lost in vain. Dozens of special forces chased after them, while others continued to defend so as not to divert the tiger away from the mountain, and let the researchers go up to the ground to avoid poison gas damage.

These researchers are valuable assets, and the death of one of them is enough to make the heart ache.

The special forces chase the killer, contact the police and the military to intercept them on the road, and must wipe out all these crazy guys and eliminate no one left.

When Lin Dong and the people of the NFF organization received the news, it was just when there was a firefight, and the poison gas had not yet been released. As soon as they hung up the phone, they received another call to report the poison gas attack on the underground research institute.

Lin Dong is not calm! The underground research institute belongs to the Huayi Group, but whether it is construction or defense, it is operated by the military. Huayi Group mainly provides technical personnel. Experts from the military were also partly involved. The underground research institute was attacked, and the exhaust holes were exposed.

In order to prevent poison gas from being thrown, many exhaust holes were designed. Most of them are fake, and even if they are true, some are spare, and some are not connected to the main air conditioning port, but are only connected to a separate room. The fact that the enemy was able to accurately throw poison gas into the main exhaust duct of the air conditioner indicates that either the blueprints were exposed, or the enemy had already checked all the exhaust holes.

Underground research institutes, ventilation is key. If there was no oxygen, they would all die underground. But now that the enemy knows about the exhaust holes, if they continue to use the underground research institute, the enemy may also throw gas bombs, causing casualties.

For the safety of the researchers, as well as the safety of the potential formula, Director Kang and Lin Dong unanimously decided that all the researchers would temporarily go to the backup base to study.

A large number of troops were in charge of this escort, helicopter escort in the sky, and dozens of military vehicles on the ground to protect it, as long as anyone dared to try to storm the convoy protecting the researchers and formulas, they would be immediately struck by thunder, without the slightest discussion.

Director Kang felt that the assault had no practical use, and that the timing of the gas release was incorrect. If you had released the poison gas first, and then wait for the researchers to run to it, the results would have been much greater. And this wave of people is definitely with the people who framed Liao Fei, and they want to take advantage of Liao Fei's absence, through this temptation, to make Huayi Group make some kind of inappropriate move.

The other party is a poison gas threat and a tough attack, obviously mainly doing superficial things, just to make the potential formula move and save it in another place, so that it can be intercepted and killed halfway.

Director Kang sent dozens of military vehicles to protect it, which was full of special forces and special police, and there were helicopters in the sky.

Everyone thought that no one dared to move the convoy, but things were unexpected, when the convoy was driving fast on You'an Road, two white eyes were issued on both sides of the road, and as the rocket hit the two military vehicles at the head, there was also a Stinger missile in the house next to it that flew into the sky, instantly hitting Wuzhi-9, shooting down a helicopter gunship.

At the same time, the sound of machine guns rang out on both sides of the road, and more than 50 killers who were lying in ambush on the side of the road opened fire at the same time, injuring and killing dozens of soldiers with a single blow.

The special forces chased out of the underground research institute and the reinforcements from the previous military have all eliminated the attacking killers, and no one would have thought that there are still so many people here, as if the city was occupied by the enemy for a while. You can pull out hundreds of combat power casually.

Even if these fifty killers attacked suddenly and blew up a plane and two military vehicles, their good luck was here! There wasn't a helicopter in the sky, another gunship was aimed at the people below and pulled the cannon button.

Cannon shells were fired one after another, and if one hit, the man would be torn apart. The land is more like it has been plowed all over again.
