I followed Zhao Tiesuo's finger and looked at the chimney on the top of the big clock, I don't know if he said that he climbed out of the chimney, but it is really hard to say where the chimney leads.

I asked Zhao Tiesuo: "Brother Zhao, you're not kidding, are you?" Climb the chimney? The chimney doesn't know where it leads, and if it leads to the ground, how high does it have to be? ”

Zhao Tiesuo didn't answer me in a hurry, but walked towards the boiler that was no longer running, and went in from the big bell that was just enough to drill through a person's window, looked up, and said to us outside: "It must be able to get out, if the hot gas is not discharged to the ground, then in a small space, it will definitely cause high pressure, and even explosion and collapse. ”

I don't agree with him, but I don't disagree, I would rather see the chimney go to the ground. But another question arises, how can such a high chimney, with our limbs, hold out?

So I said to Zhao Tiesuo again: "Brother Zhao, come out quickly, it's impossible, who can climb to such a high chimney with your two strokes?" We're not Santa Claus. ”

Zhao Tie locked it inside and said, "No problem, there is a ladder inside." ”

As soon as I heard this, was there really a play? Seeing is believing, and I also climbed in through that small window, but the posture was not as graceful as Zhao Tiesuo's. When I got inside, I saw that I could actually go up, and there was a U-shaped iron ladder that extended upwards in the chimney. However, the bottom of the chimney, that is, the top of the bell, was more than two meters above the ground, and it was very difficult to climb the first ladder.

I looked at Zhao Tiesuo and said, "Brother Zhao, how can you go up here?" Zhao Tiesuo said: "Don't worry, I have a way." ”

He first asked me to pick him up to the U-shaped ladder above, and then climbed up with the strength of his arms. When he had climbed up, he said to me, "Let everyone else in." ”

I looked through the window and beckoned the four people outside to climb in, except for Sister Hua's posture, I didn't see it better than me, especially the fat brother, who was still the most strenuous one.

During the time when everyone was climbing in, Zhao Tiesuo was on it, returning the bullets of the shotgun, tying the iron ladder with the strap of the shotgun, letting the shotgun hang straight down, and then said to me: "Try, can you come up with the gun?" ”

After the gun hung down, it was actually very low, I didn't have much effort to hold the gun body, I easily followed the gun, climbed up the iron ladder, and said happily after going up: "Brother Zhao, you really have two hits, this trick of using a gun as a ladder, we who have never even played with a gun, really can't think of it." ”

Zhao Tiesuo said: "I am in the reconnaissance company in the army, and there are a lot of strange tricks that you have not seen, and I want to learn to go back and teach you." ”

Zhao Tiesuo got out of the way, I climbed up along the iron ladder, and Yan Qiu and Sister Hua came up from behind, followed by Lu Shan, Lu Shan was a little difficult when she came up, and Zhao Tiesuo hung upside down and pulled her up. In the end, the fat brother climbed up very smoothly.

I took the lead at the top, Zhao Tiesuo and Fat Brother were at the tail end, and we began to climb up the chimney.

The inside of the chimney was very dark, and the iron ladder stretched very high above, and it was so dark that nothing could be seen. In the dark, we can only make sure that everyone is still safe by chatting with each other, the power of the flashlight is insufficient, and we are afraid of encountering something urgent, so I put it in my pocket and no longer continue to use it, and I can only see a little blue light on the fat brother's wrist.

At the beginning, Yan Qiu, who was behind her, also discussed with me, and she said: "In any case, it is impossible to imagine that the Chinese in the Eastern Han Dynasty have already mastered power generation technology, and if it were not for the advent of electrical equipment, it is estimated that it would have been popularized long ago." ”

I dispelled her suspicions and jokingly said to her, "Didn't you say that too?" 800 years before Cao Cao's time, the Greeks had already discovered the phenomenon of electricity, if our ancestors also discovered it at the same time, then it took 800 years to study, and it may not have been studied without any results. What's more, we have the most intelligent genes in the world. ”

Yan Qiu listened to my words, and said thoughtfully: "Well, according to your analysis, there is some truth. Then it was a period of silent thinking.

The chimney is indeed very high, at first there was a concept of time, I knew how long I had climbed, but then I felt that there was no end to this chimney, and my body was left with numb climbing, and my brain was already blank. Six people crawled and stopped, resting and repeating mechanical movements.

With a tired spirit, I pretended to be relaxed and teased Sister Hua and said, "Old lady Hua, do you remember how many stepladders you climbed?" ”

Sister Hua below said angrily: "Your kid has also learned to regulate your sister now, right?" So much, who is sick? Also remember. When I go out, I will clean you up and let you be no bigger or less with your sister here. ”

As soon as Sister Hua's words fell, I was punished. I was supposed to climb up smoothly, but my head hit the top all of a sudden, and I was dizzy. When I looked up, I found that we had unconsciously climbed to the top, but the situation at the top was not optimistic, because there was an iron lid on it, and I tried to push it with my hands, but there was no reflection. If this climbs any further, I'd rather let go and talk about it in the next life.

They asked me about the above.

Like a deflated ball, I said to them, "There's no road up there, and there's a cover, and it's very tightly covered." ”

Zhao Tiesuo's voice came from below, and he said, "Zhanxiao, you try, the lid will definitely be opened." ”

I shouted at Zhao Tiesuo below: "Impossible, right? Brother Zhao, why don't you climb up and take a look? It's so tightly covered that you can't push it open. ”

Zhao Tiesuo said: "I can't push it open, that's because there is water on it, and our chimney mouth is under the water." You see the iron ladder and chimney walls around it, they are all rusty. ”

I took out my flashlight and looked at it, and my hands were already covered with reddish-brown rust. I turned off my flashlight and put it back in my pants pocket. Holding the iron ladder with one hand, and pushing the lid on the top of the head with the other, the lid can be pushed, and it is fixed on one side, and the other side can be pushed open.

I pushed it with all my might, and the lid immediately opened, and a very rapid stream of water poured in through the crack, pouring cold on me.

I hurriedly let go, let the lid cover again, and then turned on the flashlight to see the situation of the people below, everyone below was affected, but Yan Qiu and I were even more wet, from above, Yan Qiu was really bumpy, and I couldn't help but be happy.

Yan Qiu looked up and found me above, staring at her with lustful eyes, and said angrily: "Hurry up and go out, I want to see you later." ”

When she said this, I felt my face burn and went back to study the iron lid.

I didn't do it, I pushed hard, and I climbed up against the coming water, and quickly drilled out, and the lid behind me was tightly closed as I drilled out.

Only then did I realize that the design of the chimney lid is actually to open and close downstream, and there is a hinge structure on the other side. When the heat comes up and the lid is lifted, the gas stops the water from backing up and draining out. The lid can be opened at an angle of no more than 90 degrees, so that if there is no hot air lift, the lid will be covered by the water rushing downstream.

The water around me was fast, but I could already feel the sunlight coming down so clearly that I couldn't open my eyes. Now I'm pretty sure I'm in a big river.

With the last of my strength, I swam to the surface of the river, and then swam to the shore, and when I climbed to the shore, I was already weak, and I lay on the shore with my eyes closed, breathing in the air outside, enjoying the illumination of my eyes.

In a moment the voices of the others came, and from the voices they could discern were not missing, and they all lay down beside me.

Thinking about this journey, it was really bumpy, some from the unknown world, some from other groups of people, but we all passed the test. My knowledge has also improved a lot, I have seen a lot of things that I have never seen before, and I have learned a lot of knowledge that I have never touched before. To put it bluntly, it's really a bit worthwhile, like attending a bizarre garden party.

Thinking of this, I closed my eyes and laughed, and this laughter contained the ridicule of what happened to me, and the relief that I came out alive.

The people around me also laughed heartily along with me.

I don't know what they laughed at, but I could hear it, and they were all laughing happily.

Only the fat brother who didn't understand the amorous feelings, lying there and said innocently: "You say, we have crossed over?" Or is it back to its original position? ”
