Dry cement production refers to a process in which the raw materials required for the production of cement are crushed and then sent to the preheating tower and rotary kiln for calcination with fans. Han Nuo, a mechanical engineer, is currently moving bricks for a company that specializes in the design of dry process cement production lines. His main business is the design of the preheating tower.

The sun was very strong on this day, and the wind was a little noisy, so Han Nuo climbed to the top of the preheating tower alone with his bag on his back. This is the first time he has climbed this equipment, the preheating tower is 63 meters high, there is no elevator or other lifting devices, and he can only step on the spiral steel ladder that has just been welded step by step. One morning, climb up and walk down again, and you can have lunch. So he walked with a slow step, his eyes glancing across the heat-up tower.

That's another tower-like piece of equipment called a humidification tower. The humidification tower is more than thirty meters high, much shorter than the preheating tower, but the people working on that equipment are obviously more dangerous than Han Nuo.

It was a welder, welding an access ladder on the outside of the humidification tower. He would weld the angles one by one to the outer surface of the cylindrical device to form a spiral staircase, and then weld the patterned steel plates and handrails in turn.

Han Nuo looked at the bold welder, and goosebumps broke out all over his body. Because the other party is walking on the ground on the angle steel, as if there is a staircase under his feet.

For such scenes, Han Nuo is not uncommon. But he couldn't imagine himself doing the same thing, after all, just imagining falling from a height of tens of meters was enough to make people weak.

However, Han Nuo was a little unlucky today. He came to the construction site this time mainly to solve a design problem on the equipment, according to the project department colleagues stationed on the site, the preheating tower is basically completed, so he chose to travel to this place where birds don't today.

But when he stood in front of the penultimate staircase, Han Nuo silently cursed his colleagues in the project department several times in his heart. The staircase in front of him, although there were complete steps, and the steps were also paved with patterned steel plates, there were no guardrails. For Han Nuo, this is undoubtedly like a moat.

Han Nuo hesitated for a while, the steps in front of him were fine, but the turntable in the middle of the stairs that was only one square meter square really frightened him. He weighed in his heart that if he didn't go on this trip, he might need to travel to the construction site once, and because the work was not completed on schedule, he might be scolded by the boss. But if you go up, if something happens, you will have everything to rest.

In the end, the anxiety of being scolded by the boss overcame the fear of the unknown, and Han Nuo decided to give it a try, in case of any danger, he immediately lay down, and then climbed down with both hands and feet. After making a decision, he fastened the buckle in the middle of the backpack strap and stepped on the ladder step by step.

As he walked up step by step, Han Nuo began to relax, he didn't expect that he could also walk on this ladder as he walked on the ground. But apparently he had no idea how high he could overcome, especially when he finally stood on that turntable.

Because of the climb, he kept looking up at the top, and he was not afraid at all. But as soon as I stood on the turntable, a gust of wind suddenly blew. The wind may not feel like much on the ground, but anyone who has ever flown a kite knows that when a kite flies to a height of tens of meters, sometimes such a gust of wind is enough to tear the kite string.

So this gust of wind made Han Nuo stumble, he stood in place and steadied for a moment, and then casually glanced to the side. This glance didn't matter, the feeling of looking down on the ground from a high altitude directly made Han Nuo feel his hands and feet weak, and he suddenly became a little dizzy. Han Nuo didn't have a fear of heights, but for a moment, he felt that his body was being blown from side to side by the wind, and he didn't know if he was shaking or if he had an illusion in his brain.

But Han Nuo knew how dangerous he was now, after all, he was at an altitude of sixty meters, and if he couldn't control his balance immediately, he might have to explain here. He wanted to squat down immediately and let the blood flow into the brain as much as possible, so that the cerebellum, which is responsible for balance, could adjust as soon as possible. But the body did not obey the call, a small squatting action, he felt that it took him half an hour.

This approach is somewhat useful, if it weren't for what happened next, Han Nuo would have had a chance to climb down with both hands and feet.

But I only heard a loud "bang", and I don't know what smashed on the equipment above Han Nuo's head. The last time I heard this sound, it was that the flange of the manhole was not welded firmly, and it fell directly from a height of more than 40 meters, and landed on a platform below, and then a scaffolding fastener on the platform bounced up and smashed on the helmet of a worker below. The workers were dizzy and dizzy, and when they took off their hard hats, they found that their half-bald scalps had all turned red.

Han Nuo subconsciously glanced in the direction of the sound coming from above, and saw a strange disc-shaped object rolling down the last flight of stairs. It looked like a flange, but he didn't have the impression that there was such a round flange above the device. He worked hard in his head, and finally confirmed that his position was the only way for the disc-shaped object to roll down, but because of the weakness of his hands and feet, he did not have the strength to dodge it.

Sometimes life is like this, you accurately predict the trajectory of misfortune, but you can't avoid it.

In the next second, Han Nuo was already flying in the air, holding the strange disc-shaped object in his arms.

Han Nuo had had that kind of dream of falling from a high altitude countless times, and that real feeling of falling could wake him up every time. But this time, Han Nuo didn't wake up smoothly, he felt that he had been falling, and at the same time, the legendary marquee appeared in his brain. In the flash of light, he quickly browsed his life from birth to the present.

He felt that his life was imperfect, firstly, the game he had just cleared last week did not have a perfect ending, and secondly, he had not been able to become a man in the true sense. The only chance in his life that he could get off the list was when a girl handed him a note that said "Hello", and Han Nuo replied "You're okay", so there was no follow-up.

Thinking of this, Han Nuo raised the disc-shaped object in his arms with some annoyance, he wanted to see the true face of this thing before he fell to the ground and fell into a mess of mud-like objects. As a result, the moment his gaze touched this object, a dazzling light appeared, making Han Nuo have to close his eyes.

After a few moments, Han Nuo opened his eyes and found himself lying on a mudflat, surrounded by the gurgling river. Han Nuo didn't get up immediately, but took a good look around with his five senses.

He could clearly see strange plants on both sides of the river, some bright purple flowers dotted among them. The sound of running water is soft, as if the river is not flowing with water but some more viscous liquid, and the smell is different from the fragrance of the earth, and there is a pungent smell. Han Nuo closed his eyes and thought for a moment, and began to believe that he had arrived at Lethe.

He got up without any pain in his body, which made him even more convinced that he was already a revenant. He still agrees with such a death, after all, there is no pain. But what made him strange was that in addition to hearing and smelling, he could also feel the senses of touch, and the soft touch of the mudflats under his feet seemed to be the same as when he was alive.

Han Nuo scratched his head, took a step back, and found himself stepping on something hard, he looked down and pulled it out of the mudflat, and found that it was the disc-shaped object that had sent him into the world. He took the thing in his hand and examined it for a while, then went to the river and washed the disc.

In the process of washing, Han Nuo was surprised to find that the disc had inexplicably become smaller, and it had shrunk to a diameter of only about ten centimeters. The surface of the disc was engraved with some strange pattern, and although it was less than half a centimeter thick, Han Nuo could feel that it was hollow. And its material doesn't look like metal, and it doesn't look like plastic, it looks like it's integrated from the outside, but it feels like there's something mysterious inside. Han Nuo stared at it for a long time, rubbing his forehead, guessing that it might be some kind of handicraft made with three-dimensional printing.

Thinking of this, Han Nuo suddenly came to his senses. If he became a dead soul, why did this foreign object follow him into the underworld of the Yin Dynasty? He touched his back again, but the backpack was still there, and he looked at his body again, but he didn't expect to bring his clothes and shoes over. This development is obviously different from the continuation of life in the afterlife, could it be that you have crossed over?

Han Nuo took off his backpack and took out the contents to feel it. The book still feels like that, and the pen can draw traces on the hand, and the handwriting can be washed off with the liquid in the river. All of this is enough to prove one thing, that is, this should be a physical, objective world. These discoveries made Han Nuo a little relieved, but he didn't expect that his life did not end there.

But what is this place? Han Nuo looked up at his surroundings, there were no animals, only lush vegetation. The mudflats where I am located seem to be alluvial tidal flats formed by this river. He reached out and picked up the liquid from the river, wanting to taste the "water". But a familiar feeling came through his head and made him give up on the idea.

Hanno is a cycling enthusiast, so he knows a little bit about survival in the wild. The first of these is that you should not drink raw water in the wild. This is because raw water may contain animal carcasses or excrement, and the bacteria contained in it may make drinkers sick. The first time Han Nuo had diarrhea in the wild was when he drank water from a seemingly clear stream, but the E. coli in it made him almost dehydrated.

And Han Nuo once again confirmed the surrounding environment on one side, the absence of animals is very suspicious, and there are no fish and shrimp in the river, which makes him confirm once again that the liquid in the river must not be suitable for his own drinking.

Being in an unfamiliar wild environment, Han Nuo knew that the most important thing at this time was not to figure out where this place was, but to get out of this place as soon as possible and find traces of inhabitation. After all, this place is so unknown, and many things do not conform to the common sense of the earth. He washed the clothes on his body with river water, but fortunately he was wearing a jacket today, the surface was not wet, and the backpack on his body was also a waterproof backpack, so the mud on his body was quickly washed away, and the person was much refreshed.

So Han Nuo began to walk downstream in the direction of the river, which was also the knowledge he had learned from some of his fellow travelers. When people get lost in the wild, they can follow the water, because places where there is water are often inhabited. He didn't know if that common sense was applicable here, but he had to do it. And the reason why he went downstream was simply because he didn't want to face the sun, after all, for him now, it is necessary to reduce the water consumption in his body as much as possible before ensuring safe drinking water.

However, Han Nuo's luck was not too bad, and after walking less than two miles, he picked up a hat on the ground. This hat looks similar to the hat Han Nuo has seen, and it seems to be made of bamboo strips, and the surface is also covered with a layer of bamboo shoot shells, which can be very good for rain. The only downside is that the headband of the hat is a bit big, and it seems that its previous owner is a guy with a head bigger than himself, so when Han Nuo wears the hat, the headband will get stuck in the part of his eye.

However, for a mechanical engineer, a small modification can overcome this difficulty. He first found some stalks on the plants next to him, and then braided them haphazardly. But I have to say that as an engineer who lives on computers all year round, he is indeed a handicap. Although the hat that he had transformed could be worn on his head, he slid off as he walked.

Han Nuo threw the hat aside in some irritation, suspecting that its previous owner had abandoned it for this reason. He pulled up the hat of his jacket and continued on his way, as if an invention from the civilized world would work better.

However, after a few moments, Han Nuo returned, picked up the hat again, embedded the disc-shaped object in his backpack in the headband, and used it to stop the hat from sliding. This time, he succeeded, and the texture of the disc was not bad on his head, and it would not make people feel bad. And after wearing the hat, the sun no longer burns the jacket.

After about two hours of walking, Han Nuo still couldn't find any traces of inhabitation. He was a little drumming in his heart, after all, if the direction was wrong, every step was more wrong. Annoyed, he kicked at a pebble beneath his feet, which bounced off the ground a few times before concentrating a dwarf plant and knocking off a fruit that looked like a date on top of the plant.

Seeing this, Han Nuo immediately ran towards the fruit, which was a multicolored fruit with a distorted rainbow-like color on the surface. Han Nuo held this fruit and made it difficult again. After all, in common sense, the more bizarre the color of the plant, the greater the chance of poison. He didn't dare to eat it, and he couldn't bear to throw it away, after all, it was the first fruit-like object he had seen so far. The plants on both sides of the river, though luxuriant, seem to be mostly stem-like plants resembling reeds, with no fruits, and the rest are unknown weeds, and they don't know what to eat.

Han Nuo, who had put the fruit in his pocket, glanced at the plant that had dropped the fruit just now, but found that the plant was gone. He looked at the pebble that was kicked away by himself and was stunned, feeling that it was not simple, but he couldn't say what the problem was, after all, in this unfamiliar environment, all common sense could no longer be applied.

In this way, Han Nuo walked in the direction of the river for almost four hours, and the sun gradually became less hot. However, judging from the light and shadow, the sun is still early to set. And he found that under the sunshine of this world, people have two shadows. This phenomenon can only explain one problem, there are two light sources.

Han Nuo didn't think about checking this issue, but the sunlight was too dazzling, and when he looked at the direction of the sun with his naked eye, he could only see snow white no matter what, so he broke off this thought.

If he continued to walk and could not find any signs of human habitation before the sun went down, Han Nuo would probably have to choose the direction to leave the river. After all, to survive in the wild, safety comes first. I don't know if there are beasts of prey in this world, but there are tall trees, and on the outside of those reed-like plants, you can occasionally see a few. From the beginning, Han Nuo planned to find a tree to climb up and spend the night if night fell.

However, at this moment, Han Nuo unexpectedly discovered that there was a wooden bridge about a kilometer or so in the distance. This discovery made him a little ecstatic. Mr. Lu Xun said that there is no road in the world, and when there are more people, there is a road. If there is a bridge, it means that there are people coming and going, and if there are people coming and going, it means that there are many people walking, and there must be a road.

Thinking of this, Han Nuo quickened his pace. Sure enough, he saw a sign of someone stepping out of the bridge, and looking out along the track, there were two rows of tall trees growing densely on either side, dividing the wall of reed-like plants into a passageway. Han Nuo looked at the road on the left, which seemed to lead to a mountain peak, and the road on the right led to the bottom of the mountain.

Now there are two choices in front of Han Nuo, one is to go up the mountain and the other is to go down the mountain. There are two possibilities, one is that the mountain is inhabited, and this road is a passage for mountain people to go down the mountain to obtain supplies. The second is that there is no one living on this mountain, and people just use this road to go up the mountain to cut firewood or carry out other production activities. Han Nuo chose the road down the mountain on the right, after all, no matter how he chose, the mountain should be inhabited.

This time, Hanno was lucky, as he did see a dilapidated house two hours later, and at this time, the sun was about to set.
