Survival Paradox [Infinite]

"Plan B?"

Wei Chi subconsciously lowered his voice, as if he was imitating No. 9's voice, but also as a precursor to some kind of anger.

No. 9 on the radio smiled unconsciously: "A foolproof way to ensure that we will not be affected by zombies."

A Piao raised the screen: [Did you hear any sound? ]

The whistling electric sound of the radio above the head continued to sound, and besides that, there was a barely audible rattling sound under the highly tense nerves. If he hadn't been reminded, others would not have noticed it.

"It's the sound of rolling curtains falling." Xu Wei suddenly realized, "Where did it come from?"

Ah Piao covered her left ear with one hand and walked around, then suddenly knelt down and pressed her right ear to the ground.

[It is below! ]

"Below? One floor?"

Ah Piao typed affirmatively: [More than one place, near and far. ]

Gao Da was surprised: "Are they trying to seal themselves up?"

Xu Wei pondered: "Or seal us up..."

Wei Chi felt a kind of distortion, and he showed a painful expression again, as if a huge stone hit the head: "No, it should be both."

Gao Da recalled what he said before the 9th, and his facial features twitched: "What do you mean, do they want us to die?"

"Hahaha, did you guess it?" At the same time as the voice of No. 9, there were also chaotic footsteps, relying on the radio to pour down from the roof, "But it's too late! As long as we run to gate 15, you will clean up Pack up and lie down and wait to be greeted..."

His last words were overwhelmed by successive cheers and gasping exclamations, leaving only the sound of short breaths on the radio.

"What did he say?" Gouda asked.

许玮发出一声叹息：“15号登机口紧邻着封锁乘客的14号,也是通往9号出口的必经之路……他们在无人机主人选择之前把15号封起来,无人机主人就不可能选择他们。不然一旦15号登机口打开,丧尸进去就相当于把进入14号和9号的路彻底封死，不管是人还是钥匙都不可能进去,没有什么东西能威胁到他们,我们被将死了。之后他们只需要在原地等着熬不下去的钥匙持有人主动找他们就行了,毕竟光有钥匙没有门也不过是废品一件。”

"But who said you have to go in to be a threat?" Wei Chi said coolly.

"What do you mean?" The voice of No. 9 suddenly sounded. It seems that even though they ran to their destination, they did not neglect to monitor the situation of boarding gate 51.

"literal meaning."

"Ha." No. 9 laughed, and after he stopped running, his voice became more confident and prepared, "It's useless to bluff now, our planB is foolproof!"

"It's just a backup plan, as if it's some great patent." Wei Chi smiled lowly, but there was no trace of happiness in the laugh, "Do you think you are the only ones who have Plan B?"

As if a start signal had been received, there was a burst of violent coughing on the radio.

At the same time, several people exclaimed: "What kind of smell is this?"

The people around him also stared at him questioningly.

Wei Chi shrugged: "Probably hydrogen fluoride."

Xu Wei's eyes widened.

Gundam covered his mouth and nose quickly: "What? Poison gas?"

"Is it another quicksilver trick?"

Sanjo said jokingly, but different from his relaxed tone, a sense of fear that could not be ignored was brewing in his heart, and the stomach that was soothed by milk burned again, bringing a sharp stimulation.

Even though he didn't want to admit it, he couldn't help realizing that although it was the owner of the drone that designed them on the surface, since the 10-minute countdown or earlier, everything here has been controlled by Wei Chi.

Thinking back now, in their tit-for-tat conversation across the radio, Wei Chi seemed aggressive, but he never asked him a question.

When his question was ignored, he chose to wait in silence instead of continuing to press, which was very different from the way he used to coerce himself and Gundam with poison in order to get information.

If that kind of appearance is his normal appearance, then these 10 minutes of Wei Chi are more like giving them a chance than seeking answers.

"No, this time it's real." Just as Santiao expected but was afraid, Wei Chi replied lightly, "Hydrogen fluoride is poisonous at room temperature."

20 minutes ago, in the depths of the staff passage, Wei Chi and Fang Qingdi.

"Then use the control system to open it, okay?"

"It's possible, but it's very difficult. To use that computer...I don't know how to do it."

"If you don't, you have to."

The two returned to the fire control room, and Wei Chi found that Mr. Fang was indeed a real person, and if he said he couldn't do it, he really couldn't do it at all, and he didn't mix any water.

Fortunately, he still remembered to carry the operation manual with him, and Wei Chi operated the internal manual with characters printed smaller than ants on the iron pan, and finally opened the explosion-proof shutter that was tricked by Fang Qingdi's will-o'-the-wisp.

Fang Qingdi watched him reset the time for the roller shutter to close again: "Xiao Wei, what's the matter? Is there a fire outside? It doesn't matter if it happened, we all have automatic fire extinguishing systems, very advanced, wow One spray, and the fire goes out!"

Wei Chi tapped the last carriage return with the ring finger of his right hand, and the reflection of the screen flashed in his eyes: "Old Fang, is the automatic fire extinguishing system gas?"

"I don't know, it's in these jars behind this anyway." Fang Qingdi opened a curtain at the back of the control room. Behind the curtain was a small wire bed. Next to the bed was a small door with a yellow After the triangle sign is pushed open, there is an airtight space larger than the control room outside, inside which are neatly placed dozens of 180-liter special gas storage cylinders, standing in groups of two in metal cabinets.

The label on the cabinet is HFC-227ea/□□00, the Chinese name is heptafluoropropane.

Wei Chi walked in, the temperature was lower than the outside, but it was not a cold storage for gasification storage, it was just an ordinary storage room, and the cylinders and tanks were connected with one-way valves and high-pressure pipes, and dozens of pipes were directly connected into the roof ventilation duct.

"Mr. Fang, I have a request." Wei Chi said earnestly, "Please use will-o'-the-wisps to burn these jars until they are boiling hot."

"This... I have never tried to summon such a big fire." Fang Qingdi hesitated.

"Please." Wei Chi faced Fang Qingdi and bent down.

"Oh, I can't help it... I can only try it. Whether it should be a matter for the other side, it all depends on fate, you can't force it."

I saw Fang Qingdi open the thermos cup, buckle a sandwich from the inside of the lid, and a small square thing fell out. After unfolding, it was a piece of talisman paper.

"This is a good thing. I kept it with tea, so I brought this one with me." After Fang Qingdi finished speaking, he held the talisman paper on his fingertips and recited the mantra.

At first, it was just a fire bursting out from the center of the talisman paper like a small flame tapped by Fang Qingdi's fingertips, but as the incantation progressed, the flames on the talisman paper suddenly erupted, sweeping all the cylinders like a flood.

The whole room was enveloped in flames. Miraculously, Wei Chi didn't feel hot in it, but the thermometer on the cylinder was rising crazily, breaking through the critical value in just a second or two.

As a scientific researcher, seeing such a scene, Wei Chi did not feel his faith collapsed, but instead made him believe in the meaning and value of exploring the world.

For example, putting aside the fantasy surface and thinking about it in essence, the essence of summoning will-o'-the-wisps is to create heat energy, so where does this energy come from?

According to Fang Qingdi himself, this fire was borrowed from another world on the other side.

Isn't the world they are in now also another world?So, does the legend of the so-called underworld also have something to do with this?

If energy can be extracted from other worlds, will anti-entropy be formed in the extracted world?Wouldn't it be possible to turn back time...

"Xiao Wei, I'm a little dizzy." Fang Qingdi said suddenly, interrupting Wei Chi's thoughts.

Wei Chi turned his head and saw a layer of blue on the old man's face, he hurriedly said: "It's okay, Mr. Fang."

Fang Qingdi tore up the talisman paper, and the will-o'-the-wisps that filled the room disappeared in an instant.There was no trace of the place where the fire had been burned, as if the spectacular scene of the stove room just now had never existed.

The torn talisman paper fell to the ground, Fang Qingdi staggered back and was supported by Wei Chi.

"Old Fang, it's too late to rest, let's go out first."

"well."

Wei Chi carried Fang Qingdi, who was breathing unsteadily, out of the small room. When he walked out of the control room, the panting old man pointed to the computer on the console: "You don't have to... take care of that?"

"It's all done." Wei Chi said, the lights in the room behind him cast a deep shadow on his face through the door.

Fang Qingdi nodded: "Okay, okay, let's go outside, the fire doors are closed quickly, we can't catch up."

Wei Chi held Fang Qingdi out of the staff passage with half resistance and half pull. The old man, who was already close to collapse, glanced at the surreal sky outside, and passed out immediately.

"Fluorine what?" Number 9 asked loudly, his voice short and tense.

Wei Chi explained very patiently: "Heptafluoropropane is a commonly used gaseous chemical fire extinguishing agent. It is colorless, odorless, low-toxic, non-conductive, and does not pollute the protected object at room temperature. It will not cause damage to property and equipment. It is very good. The fire extinguishing gas is very stable... But after high temperature, it will be different. Heptafluoropropane will decompose into hydrogen fluoride, carbon monoxide and carbon dioxide. Among them, hydrogen fluoride has a pungent smell, and it will produce white smoke when exposed to air, which is poisonous to the human body."

"What?" Number 9 yelled tremblingly, "Stop it!"

"No, it's too late." Wei Chi turned his head and saw a distance behind them, the explosion-proof roller shutter between gates 47 and 48 was slowly falling.

There was a wailing scream on the radio.

“我设定的程序是，如果在51、52号登机口中间的防爆卷帘和防火门关闭情况下，落下47、48号中间的防爆卷帘，就会自动在全航站楼除了被隔绝的48到51号登机口以外释放经过高温的防火气体。”

This is the last safety lock. If the reason for expanding the isolation range is because of zombies breaking through or too many zombies and not enough space, then when the partition between 47 and 48 is put down, the door between 51 and 52 must be opened.On the contrary, if 51 and 52 are to be blocked again while 47 and 48 are still blocked, an extreme event must have occurred, so Wei Chi set up this insurance.

Listening to Wei Chi's words, No. 9 felt that everything in front of him was gradually plunged into darkness. He roared, "The whole terminal! Are you crazy? Thousands of people are locked up there!"

"Am I crazy? You are the ones who pressed the red button." Wei Chi still maintained a calm tone, as if none of this could touch his heartstrings, "If you just want to delay your own life, nothing will happen, But you still want to send us to die while you are alive, it is not me who released the poisonous gas, but your great PlanB."

Floating between his words, a faint breath of indifference made the supposedly frivolous sarcasm heavy and breathless.

But that's not the only reason No. 9 is out of breath.

Santiao lay on the ground and shouted, "Cover your nose! Don't breathe in!"

Men No. 2 and No. 7 tried to smash open the glass curtain wall with their fists.

No. 9 was lying on the drinking pool and frantically poured water on his face. He turned his head and shouted at No. 8, who was standing still, "Xu Lu! What are you doing? Come here!"

Girl No. 8 suddenly raised her head: "It's a girl."

"what?"

"The three on the opposite side, we heard the voice, all of them are men, right?" Woman No. 8 said tremblingly while holding up the photo dropped by the drone before, "So the one missing is a woman!"

"What's the use of talking about it now?" Number 9 cried out in despair.

His words melted in the gradually thickening poisonous gas. After the last murmur, which was either a sigh or a whimper, the handsome young man with ponytail fell limply on the ground like a leaking balloon, and fell unconscious.

with six others.
