We looked away from the skeleton of the Tyrannosaurus rex and continued walking.

"I ...... I said you ...... Arrive...... Do you want to...... Leave...... Get out of here?! I...... We're not here...... Ginseng...... Visited. Hu Zaide said impatiently.

"We only need to understand the situation here before we can figure out how to get out of here, right? What else do you want? Put on wings and fly down? Cui Li's face showed a hint of disdain, and he said mockingly.

"Cui Li, what did you just say?" I seem to have something in mind.

"I just said: we have to understand the situation here before we can think of a way to get out of here, right? What else do you want? Put on wings and fly down? What's wrong? Cheng Yin, I'm just joking, don't take it seriously," Cui Li said.

Hu Zaide saw a corner of the exhibition hall with a few thick wooden boards, so he immediately walked over, took the wooden boards out, kept one for himself, and gave the rest to each of us.

"I ...... I...... I...... We...... Let's go, who knows that 'mystery man'...... Miscellaneous...... Miscellaneous...... What the...... Time...... Reappear. No...... However, in the ...... Before that, I ...... We have to be ...... sooner Can be guaranteed...... Protecting ...... Own East ...... Stuff. Hu Zaide pressed the plank tightly to his chest, looked around, and said with a nervous expression.

"Cheng Yin, it's too dangerous here. Let's get out of here. Li Ruina looked me in the eye, I nodded, put aside the wooden board that Hu Zaide had handed me, and continued to walk towards the interior of the exhibition hall.

November 6, 2021 at 12:35 a.m

Our group walked through the dinosaur skeleton display area and came to a solar energy control room. "This is the solar energy control room." I saw Li Ruina step forward and take a look at the parameters on the control room, and said excitedly: "[1] At present, the most promising solar thermal power generation system in the world can be roughly divided into: trough parabolic focusing system, central receiver or solar tower focusing system and disk parabolic focusing system. The three technically and economically feasible forms are: 30~80M focused parabolic trough solar thermal power generation technology (referred to as parabolic trough type); 30~200M POINT FOCUSED CENTRAL RECEIVER SOLAR THERMAL POWER GENERATION TECHNOLOGY (REFERRED TO AS CENTRAL RECEIVER); 7.5~25k point-focused parabolic disk solar thermal power generation technology (referred to as parabolic disk). 【1】

Obviously, the AFE Research Center uses a focused solar thermal power system.

[1] The heat transfer working fluid of the focused solar thermal power generation system is mainly water, water vapor and molten salt, etc., which can be heated to 450 degrees Celsius in the receiver and then used to generate electricity. In addition, the heat storage system of this power generation method can temporarily store heat energy for several hours to be used for peak demand. 【1】”

"I'm glad to know about solar energy, but I don't think it's the time to say this, the 'mystery man' is probably still somewhere in this AEF research center, and we'd better hurry up and find a place to get out of here." Cui Li said anxiously, but obviously Cui Li didn't think so when he saw the dinosaur skeleton before, he could only say that he was not interested in the field of solar energy.

We left the solar energy control room. Walking like the previous one is the research room that Zhang Xinran said.

"This lab houses AFE's research results? Zhang Xinran brought us here before. Xia Cheng said.

"That's right, this is the research center that Zhang Xinran said before." Li Ruina replied.

"I ...... We still ...... Or leave it alone...... What research data is available, AEF Inc. 1...... Will definitely ...... I'll figure it out myself, I'll ...... We're still fast...... Get out of here. "Hu Zaide just wants to get out of here as soon as possible.

"Wait a minute, we just opened the door of this research room before, and suddenly returned to the hall on the first floor, so wouldn't we be able to use this method to go back to the first floor now." Cui Li said happily.

"That'...... That's great, I ...... We're waiting...... What are you waiting for! Hu Zaide quickly ran towards the door of the research room, apparently his leg injury seemed to be completely healed by this time.

"Wait a minute!!" I was about to stop Hu Zaide, but he was already in front of the door of the research room.

But just as Hu Zaide was about to open the door of the research room, I pulled it back.

"Cheng Yin! You...... What are you doing...... What the! Cui Libu ...... Didn't you say it, open this ...... I ...... this door We can get out of here...... Here it is!! Hu shouted angrily at me, stammering, but I could hear his anger.

"No, I always feel that something is wrong, why the AEF research center suddenly shook and why it caught fire, all this is too strange, unless there is only one answer!!" I said.

"'Mystery man'," Lin Yun and the others said at the same time.

But while they were talking, the door of the research room opened by Hu Zaide just now suddenly appeared a wall of light filled with electricity.

"Looks like you're reacting pretty quickly!!" I don't know where the voice of the 'mysterious man' came from.

We looked left and right, and there was no 'mystery man' in sight.

"No wonder we didn't see you all the way, it turns out that you also came to the top floor of the AEF research center, but you want to surprise us?" I asked sternly.

The 'mystery man' sneered: "Yes, it's a pity that I don't know if you can see it." ”

It was at this time that suddenly several grenades appeared from around us.

"Run!! Come on!!! I shouted.

"Everyone, run in the direction of the exhibition hall!! Fast!!! Xia Cheng also shouted.

We quickly ran in the direction of the exhibition hall just now, and just as we were about to reach the exhibition hall, an explosion occurred in the direction of the research room.

As the minutes ticked by, we were exhausted, but luckily we didn't hear the 'mystery man' anymore, and he might have left the place.

While I was taking a short break, I heard a scream from behind.

"Lecturer Hu!" We all thought of Hu Zaide and quickly looked in the direction of Hu Zaide. I saw Hu Zaide rushing out of the aisle. He sat on the ground, pointed to the research room with a trembling hand, and stammered, "Fire...... Fire...... fire, the whole aisle is ...... It's on fire. ”

"Now...... How...... What to do, we ...... Finished...... We...... Finished....... Hu Zaide trembled and clenched his knees, his eyes revealing despair.

Li Ruina slowly walked to the side of the exhibition hall, one hand pressed against the glass window, the other hand tightly grasped her arm, and her eyes overflowed with tears of despair.

I, clenching my fists, watched the fire spread up little by little......

I closed my eyes.

The words of that day rang in my ears:

"Is it the world that determines our life and death? If the world is the one who decides our life and death, then let me kill the world and recreate an ending where none of us will die. ”

Yes, I said that I would kill the world and recreate an ending in which none of us would die. That day hasn't come yet, how can I be here?

I've seen enough despair, but I just want to live now.

Thinking of this, I couldn't help but shout out to them, "We're not done yet!" We're alive! Even if it's only 1% hopeful, we should try it, right? ”

"But what else can be done? We can't go any further. And there's no other way to get out of here, no! Without! Li Ruina said and lowered her head.

Li Ruina's words reminded me, and I suddenly remembered what I saw this morning: there was a farm opposite the five-story experimental base, which was facing the building, about 50 meters away from the building, and a huge white canvas was stretched on the top, as if to keep the fruits and vegetables inside.

"We can't go down, but we can fly out!" I pointed to the farm opposite.

"Fly out? From the glass windows here to the farm opposite? How can this be ......" Li Ruina just wanted to refute my words, but suddenly stopped, looked at the room on the right, and her eyes became different: "Maybe you can really give it a try." ”

"You're not crazy, are you? How is it possible to be so high? Cheng Yin: What I said before was really just a joke to put on wings and fly down, you must know that this is the real world, not a 'strange array', we are just ordinary people. Cui Li reminded repeatedly.

"Maybe it really can." Xia Cheng also agreed with our plan.

"You...... You don't ...... Not seriously, right? Hu Zaide looked disbelieving.

"We still have a chance, do you remember what I just said in the solar energy control room?" Li Ruina said.

"You said it, but what does this focused solar thermal power have to do with us flying out of here?" I couldn't help but interject.

"Of course it matters." Li Ruina took us to touch the button on the side and explained to me: "[1] The heat transfer fluids of the focused solar thermal power generation system are mainly water, water vapor and molten salt. [1] Water vapor can cause an explosion in five situations. [2] The first is the entry of a low-boiling liquid into a high-temperature system; The second is when hot and cold liquids are mixed and the temperature has exceeded the boiling point of one of the liquids; The third is that the high boiling point liquid in the stratified liquid is heated and the heat is transferred to the low boiling point liquid to vaporize; the fourth is the heating vaporization of the liquid under the closed layer; The fifth is that the liquid is in a superheated state within the system, and once the shell is ruptured, the liquid leaks, and the pressure drops, the superheated liquid will suddenly flash and cause an explosion. 【2】”

"So what kind of scenario do we use?" I asked.

Li Ruina smiled and said, "Let's adopt the fifth type. ”

She walked up to a steam controller marked with English letters, pointed to a line of signs on it, and said, "If I keep heating the liquid in this machine to make it overheated, and then attack it with a foreign object to break its shell, causing the liquid to leak and the pressure to drop, and never flash, that will cause an explosion."

"But even if it can cause an explosion, it won't blow us up safely and onto the farm." I asked, puzzled.

November 6, 2021 at 1:09 p.m

"Of course, it is not enough to rely on explosions, explosions are only an auxiliary effect. Look there. Li Rena pointed to the skull of the Tyrannosaurus rex in the dinosaur skeleton model area we had just passed.

Xia Cheng looked at the skull of the Tyrannosaurus rex and suddenly opened his eyes wide: "Li Ruina, it seems that what you said is not wrong. We do have a chance to get out of here. ”

"Xia Cheng, what kind of chance is there?" Cui Li said with a blank face.

Xia Cheng didn't pay attention to Cui Li's question, but ran directly to the Tyrannosaurus rex, knocking here and there. I saw him press a button on the Tyrannosaurus rex, and the Tyrannosaurus rex slowly swayed.

"Fruit...... Sure enough, this one swings at a constant speed. ”

At this time, I was also confused.

Xia Cheng hurriedly ran over and asked Lin Yun to take a pen and a small square piece of paper, and wrote on the paper:

The distance between the building and the farm is 50 meters, and if you want to fly over, the distance is about 60 meters, and the difference in height from the farm is about 12 meters. Although an object on Earth can move at the same speed in the horizontal direction, it will accelerate its fall in equal proportion due to gravity when falling, and the formula for calculating the time of falling from 12 meters is:

t=√2s÷g

t=time sought=?

g = acceleration due to gravity = 9.80665m/sec*sec

s = falling distance = 20m

Bringing these numbers into the formula yields the following:

t=√2×20÷9.80665=1.73s≈1…

That is, a fall from a height of 12 meters takes only 1... Second.

1.7s->60m=1s->35.29m

……

"That's not right." Xia Cheng crossed out the words on the paper again and wrote them again.

t=√2s÷g

t=time sought=?

g = acceleration due to gravity = 9.80665m/sec*sec

s = falling distance = 12m

Bringing these numbers into the formula yields the following:

t=√2×12÷9.80665=1.73s≈1.7s

In other words, it takes only 1.7 seconds to fall from a height of 12 meters.

1.7s->60m=1s->35.29m

……

……

At this point, it finally dawned on me that if we were riding on something at a constant speed, we would need to leap to the farm's white canvas in 1.7 seconds to avoid falling. But looking at the bulky Tyrannosaurus rex, even if it can move at a constant speed, it will definitely not reach a speed of 35.29m per second.

In the same way, a steam explosion can blow us away, but it can also leave us with no flesh and bones. So if the three of us hid in the skull of the Tyrannosaurus Rex and let the Tyrannosaurus Rex run all the way to the window, and then detonate it with steam, we might be able to leap from the top floor of the AEF Research Center to the white canvas at the top of the farm in 1.7 seconds.

"I see."

"You...... You...... You get the idea? ”

I nodded, looked at the steam controller, and frowned.
