The masked man in black cut off the communication after finishing talking. Lin Rui was a little annoyed and threw the communicator on the table. "Damn, they are not threatened at all."

It can be clearly seen on the monitor screen that the militants still walked to the door and began to crack the electronic lock.

"Boss, the situation is not so good. The guy who opened the door is a master." Sergey looked at the monitor display channel, "From his approach, the technology is not bad. That door won't last long."

Jonathan, who had not spoken, suddenly whispered, "You should know the final terms of the security plan. Once the situation is irreparable, you should perform the cleaning procedure."

Lin Rui turned to look at him. In fact, Lin Rui knew the final terms of the plan. That refers to the situation where there is a high degree of threat in the laboratory and it is irreversible.

Security personnel must implement the final cleaning plan. This final cleaning plan is not only to destroy the virus, but also to kill all researchers and destroy the entire laboratory.

As the final clause of the security plan, this clause is not documented, but it must be fulfilled. This is a requirement of the military.

Lin Rui shook his head, "I haven't reached that point yet."

"But they will open the door soon. We may not have time by then." Jonathan looked at him.

"Resolving to do this is two different things from having to do it." Lin Rui shook his head. "I won't do this until the last step."

"But, what if this last step is really pushed?" Jonathan asked rhetorically.

"If it's the last step, I know what to do." Lin Rui nodded.

Jonathan nodded and said nothing.

At this time, sausage hurried over, "The situation is not so good. The air intake of the basement fresh air system is blocked by poison. And there is smoke in multiple places. They should set fire outside."

"Damn it, I know what the surprise they are talking about." Lin Rui was suddenly startled, "The fresh air system in the laboratory uses the air intake and exhaust ports to bring fresh air from outside into the underground facilities.

They sealed all the air inlets and ignited them at the exhaust. The temperature of the flame will **** up the air in the basement. And combustion consumes a lot of oxygen in the air.

This will lead to a decrease in the oxygen content of the air in the entire underground facility, causing us to become hypoxic. Maybe before they open the door, we will be unconscious due to lack of oxygen. "

"Damn, they are going to suffocate us in this **** basement." Sergey's face changed slightly. "I don't want to suffocate to death."

"The laboratory has a large number of protective clothing. These protective clothing are fully isolated and have a separate oxygen supply. They can only be used for a temporary emergency." Laura said immediately.

"Tell all the researchers and staff to closely monitor the oxygen content. Once hypoxia, all of them are replaced with isolation protective clothing. This can help us support for a while." Lin Rui whispered.

"A piece of protective clothing can probably provide less than an hour of oxygen content. Moreover, if the staff plus the researchers, plus all the security personnel, the number of protective clothing is far from enough." Hancock shook his head.

Lin Rui picked up the communicator and continued to contact the secret society militants outside.

"How is it? Have you enjoyed the surprise I prepared for you?" The black masked man asked coldly.

"Blocking the inlet of the fresh air system and setting a fire at the outlet of the exhaust pipe consumes excess oxygen. This is indeed very powerful.

But since you threaten us so much, I don't plan to keep the virus. You must have collected a lot of intelligence in order to attack this laboratory. There should also be a lot of information collected on security.

So I think you should know what does the final plan and cleaning procedure mean?

I have been trying to solve this matter at the least cost, but if I really push me to this point, then there really is no good ending.

I will destroy all viruses and shoot every researcher. Let you get nothing at all. "Lin Rui said sharply.

"Dare you?!" the black masked man said angrily.

"There is nothing to be afraid of. If you are timid, you will not take this task." Lin Rui said calmly, "You now have two choices, let the fresh air system return to normal, or I will perform the final cleaning procedure."

"Damn, you..." The black masked man was furious, but he was helpless. If the virus is destroyed, he can also make up for it by capturing researchers.

But if the virus is destroyed, even the researchers will be eliminated. Then even if his mission was a complete failure.

Moreover, he did not doubt that the other party would do this. Because the information they got was written very clearly, he knew the final security plan. What does the cleaning procedure mean?

Once the other party really did this, then this action would be a complete failure.

The black-clothed masked man finally compromised. He waved his hand to remove the sandbag blocking the ventilation duct and extinguish the fire at the duct's exhaust.

"I did everything you promised. But my patience is exhausted. I won't give you any more time." The black masked man looked at the surveillance camera, "Since you are going to continue fighting with me, Then we will fight to the end. To tell you the truth, there will be at most five minutes left. The door will open and my commando team is ready."

"If you dare to launch an assault, I dare to stop it immediately. Don't forget, in the underground facility, you don't have armored vehicles and helicopter support.

You can attack, but there is not much chance of winning? "Lin Rui sneered.

"In this case, let's make a bet. Don't move those viruses and researchers. See if we can get in." The black masked man sneered.

"It's not necessarily." Lin Rui sneered. "But I promise you that we will not move those viruses and researchers for the time being. Even if you open the door, you may not be able to rush in.

If you can get rid of us before I implement the final cleaning plan, count your skills.

If you can't, you still go from where to go, at least you can save your life. "

"Yes, it's the first time I have met a stinky and hard guy like you." The black masked man looked at him and nodded.

"After the mission fails, go back and ask Red Baron, he will tell you who I am." Lin Rui said coldly, "You are not wronged by a small character like you in my hands."

"In the end, I won't be able to speak big words, the door will be opened soon." The black-clothed masked man said coldly.

"Really? The door is about to open, and my bullet has been loaded. If there is a kind, let go." Lin Rui said viciously.

His ferocious aura suffocated the black-clothed and masked militant leader of the secret society.
