Hearing that Yang Lei thought of an idea, Chen Ziyang and him glanced at each other, both of them saw childhood memories from each other's eyes, and after looking at each other and smiling, the two knew that the idea that the two people came up with was the same.

In the winter of the Northeast region, there is a national love of sports, whether it is the elderly, adults or children are very popular, this sport does not have a professional name, the local vernacular is called playing slippery.

When winter comes, the ground is covered with a thick layer of snow, and the basic conditions for the development of this sport are in place, and the thick snow on the road has been compacted by pedestrians or vehicles after time precipitation.

In this way, the compacted snow layer is very thick, and it fits closely with the ground below, and there are no gaps in the middle of the snow layer. The surface of the snow is as if it has been polished, and it is unusually bright under the sun's rays, as if it has been coated with a layer of grease, and the surface of the snow is very smooth, which is perfect for making it slippery.

Children on and from school and passers-by will find a suitable layer of snow like this on the side of the road and run a few quick steps while keeping their legs straight together and gliding quickly across the smooth snow surface.

When a certain layer of snow is slid over a very large number of times, the snow on the road will become more and more compacted under the action of pressure and friction, and the surface will become smoother and smoother, and a layer of ice will slowly appear on the surface.

When the ice appears, that is, when skating is the happiest sport, the smooth ice surface is more conducive to skating, and it only takes a small amount of effort to skate far.

This sport is especially popular on slopes with slopes, and the downward slope allows the person who has skated to slide far. Even on some slopes with thick snow, the ice path that appears as a result of the slippery slope runs directly through the entire slope, allowing those who slide from the top to the bottom of the slope.

Sometimes the ice road is so long that people who stand on the ice road need to use all their strength to keep their legs straight, otherwise they will fall down in the process. A long ice road can make the skating person feel the leg swelling and pain, and the skating is also a considerable test of leg strength.

This kind of ice road that appears on the ice road brings different happiness to people who walk on foot in winter, and even some people who don't want to skate will involuntarily run two steps when they pass by and see the ice road, and slide handsomely on the ice road, or fall.

Playing a slippery sport has brought a lot of joy to people, but it also brought a lot of troubles to people. It is not easy to walk from the bottom of the slope to the top of the slope compared to the high-speed descent.

The coefficient of friction between the smooth snow and ice surface is very small, and pedestrians often fall due to slipping feet when going uphill, and every year some older people fall down while climbing and cause fractures.

Moreover, some of the steep slopes are not even climbable by cars, especially some heavy freight trucks, and it is almost impossible to climb on such slopes covered with thick snow and ice.

In order to solve this problem, the local people came up with a solution, which is to use coal ash and other things to spread on the slope or ice to directly increase the friction, and the problem is solved.

Although this is also a last resort for the safety of pedestrians and vehicles, there will always be some younger children who look very unhappy when they see adults spreading soot on the slope, which is the thing they hate the most, because it will ruin their rare happiness in winter.

Chen Ziyang knew that the method that Yang Lei came up with should be the same as what he had in mind, which was to lay something on the surface of these very smooth black stone slabs, so that the team could use these things to reach the opposite side. But there's no soot here, and I don't know what this kid came up with.

Hearing that Yang Lei had an idea to solve this problem, the others looked at him with curious eyes, which made Yang Lei feel very otherworldly. So he straightened his chest, which was already very high, and put on the appearance of a commander giving an order, and said in a loud voice:

"Now it's all at my command. Liu Cong, you find some people to go to the buildings below the steps to find some longer wooden sticks, the longer the better, the thicker the better, as long as you can carry them.

Then let some people find some sturdier and wider planks, I know you don't know what I want these things for, you send someone to get them all over, and then I'll tell you how to do it. ”

After saying this, Yang Lei put on an unfathomable expression of a worldly master, staring at the closed palace gate opposite, motionless, and almost wisp a goatee that he didn't exist with his hand.

Liu Cong has been in contact with Yang Lei a lot of times, he knows Yang Lei's virtue of pretending to be forked, and he doesn't feel disgusted, it's good to have an idea, it's better than these people falling on the surface of the black slate with a blue nose and swollen face, so he immediately organized his subordinates to search for the items Yang Lei needed in the building below.

There are countless buildings under the stairs, and there are a lot of timber in them, although some of them have decayed, but there are still a large part of them that are relatively well preserved, which is probably related to the dry environment here.

Soon, long thick wooden sticks and thick wooden planks were transported to the top of the steps, and Yang Lei was also busy, and hurriedly organized people to start building a wooden bridge above the square paved with black stone bricks.

Yang Lei's original idea was to use a few long wooden sticks to lay on these black stone slabs, and then lay some planks horizontally on top of them, so that a wooden bridge would be built on top of the stone slabs.

However, it is possible that the wooden bridge is not too stable, after all, the wooden bridge itself may also move laterally on the stone slabs left and right, and if the range of movement is too large, it is likely to directly cause the wooden bridge to slide down as a whole.

So when he saw that the wooden sticks that Liu Cong found that might have been used as beams before were very long, and the number was also very large, Yang Lei changed his mind. He discarded the planks they had found, and used only the long sticks.

The last step is slightly higher than the smooth black slate plane, and this piece of high place can be used to fix the wooden stick, which is stuck on this high step very stable and will not slide down, which also saves a lot of work in the construction of the wooden bridge.

Yang Lei commanded the others to pick out some of the longest wooden sticks, and then stuck them side by side on the steps, and he asked people to untie a few leggings, and used the gaiters to tie these wooden sticks tightly together, which looked like they were tied into a wooden row.

The sticks were all tied together, and the stability was greatly increased, even when laid on the very slippery surface of the black slate.

In order to prevent the lateral movement of the wooden raft left and right, Yang Lei also asked people to use two wooden sticks on the left and right sides to support it diagonally, so as to ensure the stability of the wooden row, and he asked two team members to step on the ends of the two oblique wooden sticks with their feet, so that the wooden raft spread on the black stone slab became more stable.

After the wooden raft was placed, Yang Lei stepped on it with his foot, and the entire wooden raft did not move at all. Because the wooden sticks that Liu Cong found were very long, the longest wooden stick in the wooden row was about to touch the palace gate opposite. As long as you stand at the farthest point of the wooden raft and jump hard, you can jump directly over the last two black stone bricks and jump directly to the gate of the palace.

Seeing that Yang Lei's method was feasible, the others all smiled. Then Yang Lei turned to Chen Ziyang and said, "Er Yang, you are my good brother, this idea was mine, you should support me, how about it?" You're the first to go up and give it a try. ”

Yang Lei's words almost didn't make Chen Ziyang so angry that he vomited blood, good guy, you can't think of me, I don't know if it can be done yet, so I thought about selling my brother first. However, since Yang Lei made this request, Chen Ziyang was not easy to refuse, so he was the first to step on the wooden row.

Whether it is said or not, these thick wooden sticks used for construction are very tight and heavy, and Chen Ziyang, who walked on the wooden raft, found that the bridge made of this wooden raft was much stronger than he imagined.

The first time he stepped on a slope paved with black stone slabs, Chen Ziyang felt that the angle of this slope was larger than he imagined, and it seemed that the arrangement of these black stone slabs was very exquisite, the purpose was to give people the illusion that this was a flat land, so as to underestimate the role of these black stone slabs.

And it turns out that the purpose of the people who built this black slate square has been achieved, and these black slabs have indeed caused the team to suffer a lot of losses.

Chen Ziyang, who walked steadily on the wooden raft for 20 meters, soon walked to the end of the wooden raft. The length of the thick sticks that Liu Cong found was uneven, and the last part of the wooden row was only three wooden sticks side by side, and then he took a few steps forward, and now the longest stick was under his feet.

The single-plank bridge is really difficult to walk, especially since it is already the end of the wooden raft, and there is no support near the longest wooden stick, Chen Ziyang, who is walking on it, feels that his feet are dangling, but he can barely maintain his balance.

Then he came to the farthest point of the wooden platoon. Standing here, Chen Ziyang only needed to leap forward to jump out of the range of the black slate.

"Eryang, you just stand there and don't move, if you stand there, you can make the wooden row more stable, and when all the other people walk onto the wooden row, you can jump over one by one." Yang Lei shouted loudly at Chen Ziyang.

Although Chen Ziyang was very depressed that Yang Lei had sold himself so thoroughly, he also had to admit that this kid's head was still very sufficient, and he deserved to study architecture. With yourself pressed against the end of the wooden card, the stability of the wooden bar will be greatly increased, especially in the second half, so that it will be much easier for others to try to pass.

Seeing Chen Ziyang safely walking to the end of the wooden row, the rest of the team was relieved, and stepped on it one after another under Yang Lei's arrangement.

The people who had fallen with blue noses and swollen faces before said that they didn't want to go up first, they volunteered to help in the rear, and helped Zhang Linfu and Guo Huaxing up first, and then helped up Daogu and Yasheng, Liu Cong and others followed.

When Jia Da stepped on the wooden raft with square steps, Chen Ziyang obviously felt that the wooden raft under his feet was much more stable, and it seemed that sometimes it was still very useful to be heavy.

Soon there were more than a dozen people standing on the wooden row, and when Chen Ziyang saw that it was almost there, he was about to turn around and jump in front of the gate of the palace. But just when he was about to exert his strength, he suddenly felt that the sky was spinning, and it was dark in front of him, and he felt that his body was slipping rapidly.

All the black stone slabs were flipped up at this moment, revealing pitch-black caverns underneath the black stone slabs. The entire raft was lifted up directly when the black stone slab was turned up, and Jada, who had just stepped on the raft, was directly flipped off the raft and rolled down the steps to the bottom.

Compared to Jada, who had a bruised nose and swollen face, the other people standing on the wooden raft were not so lucky. All of them flipped up with the rafts, one by one falling into the holes under the black stone slabs.

After a second, Chen Ziyang felt that his head was a little brighter, he thought that he had slipped down the slope, but by the light of the headlamp, he realized that he was sliding down a passage with black stone slabs on all sides.

These black slabs were exactly the same as the ones I had seen before, and they were all very smooth, so that they were falling faster and faster, and there was no place around them that could be used to borrow strength.

After hitting the black stone slabs on the left and right sides back and forth a few times, Chen Ziyang had no choice but to stretch out his arms to stabilize his body and let his body slide, because he found that he couldn't control the speed of the slide at all, even if he supported his hands and feet on the side wall, it was useless, these black stone slabs were too slippery.

No one thought that the black slate that had been stable before would turn over, Chen Ziyang secretly screamed in his heart, with this faster and faster downward speed, if there is a stone wall in front of him, his feet will fall directly, and the lightest result at that time will be that the two legs will be broken together, and if it is more serious, it may be directly killed.

The more he worried, the more he came, and by the light of the headlamp, Chen Ziyang saw a pointed object appear in the middle of this passage, and it turned out that the passage began to fork here.

In this place, the passage became a "human" shape, divided into two passages, left and right, and Chen Ziyang knew that he had to choose a passage, otherwise he would crash into the pointed stones.

At this time, a feeling appeared in his heart that one of these two passages should be a dead end, which would directly lead to the death of the people in the passage.

But because the speed of the slide was too fast, there was really not much time left for him to think, Chen Ziyang gritted his teeth, and he couldn't care so much, he twisted his body violently, turned to the right, and slid down against the passage on the right.
