"I hope so, too, but we'd better verify it. Lin Rui looked at the drawings, turned his head and glanced at him and said, "In almost all underground facilities, ventilation is the primary problem. The ventilation ducts in the conference room go straight to the outside of this building, so it should be good. ”

The black bodyguard nodded, "Yes." However, it is impossible for these ventilation ducts to infiltrate any enemies. Because the building was built with safety in mind, the ventilation ducts were designed to be very narrow and long, with a height of only a dozen centimeters and a width of more than a meter. In this case, it is impossible for someone to sneak through the guò ventilation ducts. Unless that person can squeeze himself and stuff himself in. The rest of the bodyguards laughed as well.

They all felt a little redundant about Lin Rui's unnecessary worries, although Lin Rui and the others had really made them feel powerful before, but they always thought that they had been working here for several years and were obviously more familiar with the situation here. So I was a little unimpressed with Lin Rui's opinion.

Lin Rui thought for a moment and said, "Maybe they don't have to come in at all." Let's go, take us to see those vents outside the building. I think if they really had a plan, they would have been able to find some traces. ”

"But there are dozens of these vents, scattered around the building. I don't quite understand what we're looking for......" the black bodyguard hesitated.

"Then look for them one by one. When you actually see it, you'll understand what I mean. Lin Rui took the architectural drawings and walked in front. The black bodyguard was a little worried, "But in less than an hour, the meeting is about to start, and several generals of the military have already arrived." If we leave now......"

"Don't worry, there's our guys watching upstairs, and it's going to be okay for now. But like you said, we'd better take care of this before the meeting starts. Lin Rui nodded and said, "Let's go, we're pressed for time." ”

Coming to the outside of the military government office building, Lin Rui and Peng Lefeng followed those bodyguards to check all the way. These vents are set up very discreetly, and they are really small. Generally, it is close to the surrounding green flower beds, and some are close to the ground, so you can't tell that this is a ventilation duct if you don't care. People can't get into it at all, and even a child can't squeeze into it at a height of more than ten centimeters.

The black bodyguards shrugged and said, "This is one of them, vents like this, there are a dozen more in the vicinity, and there are a dozen on the other side of the building." The entire underground facility relies on these ventilation facilities to keep the air circulating. ”

Lin Rui nodded after looking at it, then squatted down and reached in with his hand to touch it, frowning slightly, he seemed to have touched something like dead grass. The ventilation duct itself is relatively close to the ground, so it is normal for some dead grass to be blown in. However, there seems to be a lot of dead grass, and it doesn't look like ordinary grass. Lin Rui pulled out some and looked at it, put it in front of his nose and sniffed it, and said with a slight smile, "It's dried kelp." ”

"Kelp?" Peng Lefeng said in a daze, "What does this mean?"

Lin Rui turned to the black bodyguard and said, "Let your people seal off this perimeter first and check the ventilation ducts one by one." Find out if there is a similar situation. The black bodyguard didn't know what he meant, but he listened to him anyway, and checked all the ventilation ducts one by one, except for a few pipe entrances, and the rest of the pipe entrances seemed to have this kind of kelp like hay leaves.

The black bodyguard himself felt a little scratched, he didn't know what it was. He couldn't tell why the dried kelp-like plant filled the vent.

Lin Rui looked at the neatly manicured lawn nearby, and said lightly, "Is there a new gardener or gardener or something recently?"

"It's not very clear, you wouldn't suspect that someone was sneaking in pretending to be a gardener or gardener, but even if there were new gardeners or gardeners, they wouldn't have access to the building. As soon as they approach the building, they are blocked. If they could not give a normal reason for approaching the building, they would even be shot on the spot. The black bodyguard frowned.

"But they're moving around here. Lin Rui nodded. "I don't think you know what these kelps do, do you need me to explain them to you?"

"I really don't know. The black bodyguard frowned.

Lin Rui nodded and said, "These dried kelps are bandaged into a long and narrow shape and placed at the mouth of the ventilation pipe, as long as they come into contact with water. The kelp, which was originally dry, would immediately swell and completely block some of the ventilation ducts. And a gardener and gardener watering this lawn, this should be quite normal, no one will doubt it, right?"

"This ...... Do you mean that the enemy pretended to be a gardener and completely sealed the vents with these dried kelp, in an attempt to suffocate the people in the underground buildings? After all, they didn't seal them all, do they want to suffocate people, but there are still a few left, and there are no blocked vents?" the black bodyguard said inexplicably.

"Who said he must be suffocating the people below. Compared to nerve gas, the rate of suffocation from hypoxia is too slow. The reason why this person sealed part of the vent was to avoid air circulation and reduce the concentration of poisonous gases. Lin Rui said slowly.

"Nerve gas!" the black bodyguard said in shock.

"Tabun Salin Soman and the famous VX are dangerous poison gases that can kill people invisibly and silently. Most nerve gases are even fatally as low as 10 milligrams. Lin Rui said slowly, "You only need to pour a small amount into the vent to let the poisonous gas spread in the basement." And in that enclosed space, it only takes a few minutes for the poison gas to reach lethal concentrations, and the generals who are meeting below are still unaware. In a few minutes, no one will be spared. ”

The black bodyguard's face was dripping with sweat, and he said in a trembling voice, "But isn't chemical gas internationally prohibited?"

"There are many things that are banned internationally, including the prohibition of the illegal use of child scouting. But how many people do you see complying? How many African children take to the battlefield every day with automatic weapons in the midst of wars and chaos in Africa? And it's not used on a large scale, and at most dozens of people are poisoned. Who will pursue it, and even if it does, who will prove that these things are related to General Dunby's Alliance for the Liberation of Freedom?"

Lin Rui sneered, "Besides, once Harlot and his generals are dead. General Dunby's capture of Santujak was only expected. When the time comes, who will question the victory over a winner? Don't forget, history is written only by the winners. ”
