Remember [New] in a second! A total of people from five countries participated in the operation. When they arrived at the place, they knew that the exact mission was in an underground experiment base, where riots broke out, and they needed to rescue the experimenters.

And what they researched there was an illegal experiment, which belonged to the underground project conducted by the United States. At that time, the weapon they experimentally researched and researched at that time, as long as it was released, it was enough to destroy the existence of half of the earth. horrifying.

So that operation was also carried out under absolute secrecy. Frank who participated in the operation did not know how serious the matter was, but when they entered the laboratory to rescue the experimenters, one of the doctors was very abnormal and hugged a doctor tightly. box.

In the end, in desperation, he handed the box to Frank and asked Frank to take it out. At that time, Frank's goal was to take all the experimenters out. He didn't understand what this person was going to do.

However, just as they left the laboratory, a violent explosion suddenly occurred, and a group of masked armed men suddenly shot at them. At the same time as the explosion, these people also rushed up.

They didn't have time to react, and the powerful explosion shattered them to pieces. Those researchers were also killed and injured.

Frank's luck was better. At that time, he was blown into an abandoned pipeline and escaped the catastrophe. He vaguely heard the order from those people, which was to kill these researchers and not release them. any researcher.

They don't care about the soldiers who were killed, but they re-injured the wounded so that they could not fight back.

Frank hid in the pipe and watched all that indifferently. He watched his comrades fall one by one in front, but he didn't dare to make any sound.

At this time, he remembered that the box in his hand was given to him by the doctor before. What is it that is so insane that it wants to kill everyone.

But because of the violent explosion just now, the contents of the box were also damaged. Only half of the box was still in his hands, and the other half had been completely burned, and the documents inside were also destroyed.

Frank, according to the remaining half of the clues above, only roughly learned that there is a very powerful weapon that is also very destructive, and what they are studying is this project.

There is also half of the researcher's notes inside. Most of the things recorded in the notes have been destroyed, but some fragments can be seen imitated.

Probably because their research was very peaceful at the beginning. All five countries participated in the research, but after the research was completed later, everyone began to reveal their nature. After all, everyone wanted to obtain this powerful weapon and did not want to share it equally.

Disagreements arose later. The United States wanted to seize it directly because their military capabilities were number one at the time.

They have already sent people to take action twice, but they all ended in failure. After all, the defenses in the basement are also very strict.

After that, they turned their faces completely. In the end, in order to appease everyone, people from the five countries could only send their respective teams to take the experimenters out to study and temporarily stop. As for the research on weapons, we will talk about it later.
