Compared with the University of Chicago, the guards here are much stricter, such a large number of scientists, it must be well protected, just outside the venue where they are meeting, there are more than a dozen armed policemen, and even snipers on the commanding heights of the opposite building.

Scientists are the most valuable asset to any country.

Now, these scientists are determining the future of the American nation, and they want to build a laboratory here, integrate the resources of several universities, and work together to conduct nuclear bomb research here.

They didn't know that at this moment, just above their heads, in the ventilation duct, a person, was crawling gently.

The man's body was thin enough to allow him to crawl slowly in the ventilation tunnel, but he wore a burden on his head.

The rubber products covered his entire face, only the two lenses on the front allowed him to see the outside, and under the mouth, there was a large filter.

Those who are familiar with it will know that this thing is a gas mask!

He was careful not to make the slightest sound in every move, and finally, he stopped, and through one of the blinds below, he could see the light below, and inside, a meeting was going on!

With his rubber-gloved hands, he carefully took out a small bottle from his body, gently turned on the switch, and inside, the colorless and odorless gas slowly volatilized.

He crawled again with difficulty, back in the ventilation tunnel, which was impossible, and he had to continue to crawl forward to the room around the corner of the hallway before he could get out.

At the same time, he had to speed up, because the poison gas was so powerful that it would kill all the people below in a matter of minutes.

During World War I, poison gas was used on a large scale, and even Hitler was a victim of poison gas, resulting in temporary blindness of his eyes.

However, in World War II, there was no large-scale use of poison gas, because World War I had made people realize that poison gas warfare was a lose-lose way of fighting, and even if the wind direction changed abruptly, they would be unlucky.

Therefore, no one is concentrating on the development of new poison gases anymore, and only the people of the island countries still have a soft spot for it.

Just two years ago, researchers G. Schrader, O. Ambrose, G. Lüdiger, Van Schrader, Farben in Germany, and Van Anderson, researchers from Farben in Germany, G. Schrader, O. Ambrose, G. Lüdigger, Van Ander, Francis. Bender? For the first time, Linde discovered a by-product of a new type of insecticide that was so toxic that they named it "Sarin" after the five letters of their four surnames.

Yes, this is the famous sarin gas! It was only in World War II that no one used it, and it was not until after the war that this poison began to be produced around the world. The US military code name GB, the Soviet army code name P-35.

And now, Germany is only used by agents, because it is the latest development, and even if it is done, there is no direct evidence that Germany did it.

The poisonous gas is already slowly spreading.

Generally speaking, industrially manufactured sarin is pale yellow or yellow-brown and has the aroma of fruit, but pure sarin is absolutely colorless and odorless, killing people invisibly.

"Now that we've all agreed to set up a lab here, we'll have to hurry." In the conference room, Oppenheimer said: "I propose that the research institutes of several of our universities be relocated within a month, and this will definitely become a paradise for our scientists in the United States, where PhDs are nothing." ”

After Oppenheimer said this, everyone present laughed, but at this moment, Oppenheimer felt that he was a little out of breath?

He wanted to continue talking, but he couldn't help but take two big breaths, and then he felt that the more he breathed, the more he couldn't breathe, and his feet were unstable, and he fell to the ground with a pop, and then his legs began to twitch violently.

Oppenheimer's words were not finished, he could no longer speak, or rather, he could not breathe at all now.

When he breathed sarin, the acetylcholinesterase in his body was irreversibly inhibited, his pupils began to shrink, he had difficulty breathing, his bronchial tubes were narrowing, and he was convulsing involuntarily.

At this time, everyone else present also reacted in the same way, everyone realized what was happening, they wanted to call for help, but no one could shout.

In order to protect them, there is a force of guards guarding them outside, however, for the sake of secrecy, their rooms are soundproofed, after all, the guards are not completely reliable, at least not to let them hear what they shouldn't hear.

And now, this is the opposite, they want to call for help outside, but no one can make a sound!

When sarin poisoning, it will suffocate to death within a few minutes, it is a nerve gas, the lethality is quite powerful, even if it is rescued, this poison gas can also cause damage to the nerves, brain and liver, causing countless sequelae and complications, and finally let people die of this complication.

And now, the people present, died painfully and walked very fast ...

Half an hour later, Robert's secretary hurriedly walked over.

"I have urgent information to inform Secretary Robert." The secretary said, holding in his hand a document that had just been sent by the White House.

A terrible explosion occurred in one of your bases, and that base is connected to these scientists!

After checking his documents, the guards let him go, and the secretary was dumbfounded when he pushed the door open.

The room was full of dead people!

The secretary pulled his legs and rushed inside, but after walking a few steps, he fell down, and the guards outside reacted, quickly put on gas masks, and walked in, but unfortunately, there was no need to call an ambulance.

The entire scene was cordoned off, and FBI agents investigated for several days without catching the killer, and they didn't even know what kind of poison was among these people.

………

"It certainly wasn't an accident, it was completely premeditated!" In the White House, one bad news after another came almost like a marquee, making the top leaders of the United States all dumbfounded.

Roosevelt was furious.

When he was woken up from his sleep, it was an explosion at the Oak Ridge base, and when he arrived in the conference room, more murders were reported.

Obviously, this is the Manhattan Project for the United States, and at this moment, the Manhattan Project is hurting the muscles and bones, and there is even a risk of miscarriage.

Who did this to you? It's not an island country, it's Germany! These two countries will not watch the United States develop nuclear weapons.

Wait, how did the US nuclear program leak?
