Compared with the University of Chicago, the guards here are much stricter. Such a large number of scientists must be well protected. Just outside the venue where they held a meeting, there were more than a dozen policemen carrying guns and ammunition, and even at the commanding heights on the roof opposite, there were snipers.

Scientists are the most precious asset for any country.

Now, these scientists are determining the future of the United States. They want to build a laboratory here, integrate the resources of several universities, work together to conduct research on nuclear bombs here.

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

This person is very thin so that he can slowly crawl in the ventilation duct, but there is a burden on his head.

The rubber product covered his entire face, with only the two lenses in front allowing him to see what was happening outside, and there was a large filter can under his mouth.

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

He was very careful every time he acted, without making a sound. Finally, he stopped. Through a blind below, he could see the light below, and there was a meeting in there!

He carefully took out a small bottle from his body with his rubber gloves, and gently turned on the switch. Inside, the colorless and odorless gas slowly evaporated.

He crawled hard again and retreated in the ventilation duct. It was impossible. He could only continue to climb forward and climb to the room at the corner of the corridor before he could come out.

At the same time, he had to speed up because the poisonous gas was too powerful and would kill all the people below in just a few minutes.

During World War I, poison gas was used on a large scale, and even Hitler was a victim of poison gas, causing temporary blindness to the eyes.

However, in World War II, there were no large-scale use of poison gas, because World War I had already made people realize that poison gas war was a way of losing both sides, and even if the wind direction suddenly changed, they would be in trouble.

Therefore, no one is dedicated to developing new poison gases. Only the islanders still have a special liking for it.

Just two years ago, researchers from Farbourne, G. Schrader, O. Ambrose, G. Lüdiger, and Van Del Linde first discovered a by-product of a new type of insecticide, which is very toxic, so they named the poison "sarin" with the five letters in the surnames of the four people on their side.

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

Now, Germany is only used by agents because it is the latest development. Even if it takes action, there is no direct evidence, which shows that it was done by Germany.

The poisonous gas is slowly spreading.

Generally speaking, industrially manufactured sarin is light yellow or yellow-brown, and has the aroma of fruits. However, pure sarin is absolutely colorless and tasteless, killing people invisibly.

"Since we all agree to establish a laboratory here, we must be quick," Oppenheimer said in the conference room. "I suggest that our research institutions at several universities will be relocated within a month. This will definitely become a paradise for scientists across the United States. Here, a doctorate is nothing."

After Oppenheimer said this, everyone present laughed, but at this moment, Oppenheimer felt why he was breathless?

He wanted to continue talking, but he couldn't help but breathe twice. Then, he felt that the more he breathed, the less he could get up. His feet were also unstable. With a thud, they fell to the ground. Then, their legs began to twitch violently.

"Hurry, call someone..." Oppenheimer said, before he could finish his words, he could no longer speak, or he could not breathe at all now.

After he breathed in sarin, the acetylcholinesterase in his body was irreversibly inhibited, his pupils began to shrink, his breathing was difficult, his bronchials were shrinking, and he was twitching involuntarily.

At this time, the others present also reacted the same way. Everyone realized what was going on. They wanted to call for help, but no one could shout out.

To protect them, there are guards outside who guard them, but for the sake of confidentiality, their rooms are soundproof. After all, the guards are not completely reliable, at least they cannot hear what they shouldn't have heard.

But now, this has had a counterproductive effect. They wanted to call for help from outside, but no one could make a sound!

When sarin poisoning occurs, it will suffocate and die within a few minutes. It is a neurological poisonous gas and has a very powerful lethality. Even if it is rescued, this poisonous gas can damage the nerves, brain and liver, causing countless sequelae and complications, and eventually causing people to die from this complication.

And now, the people present died in pain and walked very quickly...

Half an hour later, Robert's secretary hurried over.

"I have urgent information to inform Secretary Robert." The secretary said, holding a document just sent by the White House.

A terrible explosion occurred at one of our bases, and that base is connected with these scientists!

After checking his ID, the guard let it go. The secretary was stunned when he opened the door.

All in the room were dead!

The secretary rushed inside, but after walking a few steps, he fell down. The guards outside reacted and quickly put on gas masks and walked in. Unfortunately, he no longer had to call an ambulance.

The entire scene was blocked. FBI agents investigated for several days, but they did not even know what poison they were among the people.

………

"This is definitely not an accident, it is completely premeditated!" At the White House, bad news came almost like a revolving lamp, which made all the American senior officials stunned.

Roosevelt was angry.

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

It is obvious that this is aimed at the Manhattan plan in the United States. At this moment, the Manhattan plan is in trouble and even has the risk of miscarriage.

Who did it? It’s either an island country or a Germany! These two countries will not watch the development of nuclear weapons by the United States.
