Liu Wenbing survived the disaster and said he was lucky. However, after he survived from the brink of death, Liu Wenbing made some changes. Take his view on "retro tracks" as an example, it was completely different from the previous one.

In fact, after Liu Wenbing experienced two life and death tests, he felt a vague sense of defiance and change his fate. He certainly did not realize it himself, but his confidence naturally improved. Liu Wenbing, who was not strong in his personality, also had a strong mindset. The heroic spirit of "man conquering nature" in his subconscious began to rise. Liu Wenbing seemed to feel that many things in the world can actually be subverted.

"Retro rails" are a bit weird, even a bit against the historical trend, at least unscientific! Before that, Liu Wenbing simply thought that such a choice was completely short-sighted. But now, Liu Wenbing always said that "the right one is the best", claiming that at the moment, "retro rails" can be called the most suitable carat road solution, no one.

Liu Wenbing completely turned to the retro style of the road. Tang Kai was very excited, Han Huanzhang was very excited. Ma Fen could only smile bitterly, mom! Liu Wenbing got sick and his mind was so funny! Wang Feng was not very fierce in his opposition at first, but now he has become a role in making soy sauce on this issue.

But no matter what, whether it is against or agree, the "retro rail" test project personally arrested by Han Huanzhang has been paved. This is a 500-meter ring rail, which fully considers the turning radius. The rail is made of concrete, and the middle of the entire rail is high and the sides are low. I don't know what the design effect is. The cement is hardening now and it will be tested in five or six days.

In terms of creativity, it comes from Tang Kai, but the host is Han Huanzhang. In this process, Han Huanzhang did not add his own private work. Of course, the specific implementation is Guo Huazhang. In terms of execution ability, no one can compare with Guo Huazhang, and even Biao Dafa is inferior to him.

But Bu Dafa had no interest in fighting with Guo Huazhang at all. He was addicted to playing arson during this period!

There is also a considerable technical content in arson in tropical rainforests. The climate here is humid, and humanely it is "dry fire", which is not bad! With dry firewood, the fire can be burned immediately. Unfortunately, although the plants here are lush, they are not suitable for firewood. They are either unable to burn at all, or they are troublesome, and there is also a lot of smoke. A small forest caught fire, and a radius of more than ten miles was shrouded in smoke. The whole sky was black and black, and people could not be seen clearly from a few meters away.

"Brother, why is this attitude comparable to the sandstorm in Beijing? It is said that killing and setting fire is the profession of this guy named Bu, but I didn't expect that the professional arson did not pay attention to the technical content when setting fires." Tang Kai complained.

"Hehe, I think this visual effect is very good. The poem says 'The lonely smoke in the desert', and the visual effect is amazing! 'The rain forest is smoky', haha, no one is not fucked by the smoke, my fuck, the visual effect is so spectacular, but the smoke effect is so fucking."

When he heard Han Huanzhang's bad artistic tone, Ma Fen was very dissatisfied:

"Bad! It's also a visual effect! You can see everything clearly! Visually! How can that passage be said? The farthest distance in the world is holding your hand but not seeing your face. This is talking about the haze in later generations. If I want to say, haze is a fart! Compared to this, it's simply weak."

"Director Ma, I think it's better to smoke the thick smoke. It's nothing. To eradicate malaria, you have to smoke it like this, and smoke all the harmful insects, especially the hateful mosquitoes, to death. This is why I am Lao Liu." Although Liu Wenbing survived death, he was really scared of the malaria parasites that spread malaria. He knew that it was impossible to burn all the mosquitoes with one fire, but at least one fire after another, it would have some mosquito-killing effects.

The smoke became thicker and more intense. The arson area was separated by seven or eight kilometers, but the smoke rolled in and seemed to be about to spread to the sea soon.

The four people ran out of the smoke and finally could see each other's faces clearly. The three of them had smoke and dust on their faces, and their eyes were red like rabbits, with their images particularly funny. Tang Kai laughed first, and then the four of them laughed together.

The fire there went through a period of thick smoke brewing. At this moment, it gradually became a fire. The smoke was no longer as fierce as before. The fire in this area of ​​mountains and forests turned to the prairie fire stage. However, the tropical weather changed as soon as it changed, and suddenly it started to rain without any warning. The sky was covered by thick smoke. It was already impossible to tell whether it was sunny or cloudy, and it was even more impossible to see the dark clouds coming.

The rain is getting heavier and heavier, and the sky becomes like the nighttime in the haze formed by smoke, rain fog and steam.

Not long after, the fire was extinguished by a heavy rain. When the sea breeze blew, the smoke slowly dissipated. After a long time, only wisps of residual smoke were left in the distance, and it was hard to tell whether it was smoke or steam.

Cutting down, setting fire, cutting down, this is the work that Bu Dafa led to do. Anyway, time is not so urgent. If the heavy rain extinguishes the forest fire, it will be better to burn it again. In the environment of tropical rainforest, there is no dry season in a completely meaningful sense, and it is impossible to burn a fire into a prairie fire, and it will only burn it one by one. In two months, no matter how difficult it is to burn it, it can still burn a field that runs through the east and west coasts.

As soon as the heavy rain stopped, the smoke from the Isthmus began to rage again, and the days passed by little by little in the smoke.

On this day, Long Jiu has arrived.

"Good! It's half the distance, Director Ma?" Ma Fen was the initiator of the arson. Long Jiu looked at it in the faint smoke, and a burnt field stretched inland, which really made people feel very fulfilled. Long Jiu still wanted to admire Ma Fen.

"Haha, this is nothing. There are more than ten days left, and it is probably only through the world. The arson has no technical content and is not as popular as the 'Greek Rail' created by Dr. Tang and Korean artists. Long Jiu, I am a minority now. You won't agree with them doing it nonsense, right?"

“What is 'Greek Rail'?”

Long Jiu was a little confused.

So, Long Jiu was taken to the ring rail test yard.

The five time travelers who were advancing west were all accompanying each other, and the one who commanded the test drive was Guo Huazhang.

A circular track with both sides of the middle raised that Longjiu saw was flush with the ground.

Walking on the side of the rail, Tang Kai pointed at the rail and introduced:

"You see, the two rails are cast separately, and the shape of the rail is L-shaped. Because it is a test rail, the thickness is only 15 cm, the width is 28 cm, the width of the flat part is 20 cm, the height of the rail is 8 cm, and the width of the rail is 8 cm, and the wheels of the carriage are limited by the 8 cm convex rail, so they can only rotate on this 20 cm flat path."

When Long Jiu looked at it, these were two L-section cement lumps with angle steel styles? Arranged opposite to each other, it was a section of rail. The other parts of the rail were filled with soil, and the middle was filled with soil, and the height was just flush with the rails at eight centimeters high. From the cross section, it was a wide and short boss that was higher than the reference plane and eight centimeters higher than the reference plane. The main component of the boss was two L-shaped concrete components, and the middle was filled with soil, which was that simple. As for why the soil was filled to the same height, there was a reason - this design had an advantage, that was, it would not produce water in the middle.

The rail part is made of concrete, and the others are filled with soil. Well, it saves cement.

"One meter L-shaped track has 0.05 cubic concrete on one side. If it is double-sided, 0.1 cubic concrete on one meter track is still very economical." Tang Kai studied business administration and thought that the "retro rail" he created was economically cost-effective.

"Oh, I don't know how to run?"

Having tried it before, Tang Kai was of course full of confidence. As soon as Tang Kai made a gesture, the driver over there understood and immediately blew the whip. The carriage that had been waiting on the rails began to gallop.

This is a horse-drawn carriage, which uses traditional wooden wheels. The four hooves of the towed horse flew over the raised road surface in the middle. The two wheels of the carriage are embedded in the rails and rotate rapidly, and it looks not slow.

"Let's go, try getting in the car and sitting." Han Huanzhang came over and warmly invited Long Jiu to get in the car and sitting.

The carriage ran for two laps and stopped. Long Jiu was very excited and got on the car with Han Huanzhang to take the test ride.

This is a traditional carriage with almost no shock absorption mechanism. The feeling of bumpiness when the carriage runs is still very obvious, and you may feel the rushing left and right. This should be caused by the collision between the wheels and the rails when turning. Despite this, Long Jiu felt that it felt much better than riding a carriage on a dirt road.

"How is it? It's okay! How many kilometers can you run?"

"This track has to turn at all times. If you can't run fast, you can get the most 35 kilometers. If you are on the formal track, it would be easy to run 45 kilometers per hour."

"Well, it's not bad! If this rail carriage is equipped with shock absorbers or something, I believe the comfort level can be further improved."

In fact, Long Jiu came to transport food and grass and military funds this time. Because he received news that the three of them had malaria, he came here in person.

The reason why some military funds were sent this time was mainly to prevent the King of True Wax from sending troops to the Isthmus of Kra. The Krais is nominally a territory of True Wax. Although the jurisdiction is not only equivalent to the "limitation" of the Song Dynasty, small-scale incidents are like the last small conflict of hundreds of people killed or injured. It is estimated that the King of True Wax has no time to take care of it, but if there is a big stir, the King of True Wax must also send troops to come. In order to make the King of True Wax have no time to look west, Chen Liang had already incited Chameng to swing the sword westward. It is estimated that the King of True Wax is already nervously preparing for the attack on Chameng.

When I came here, I saw that the three guys with malaria had recovered as before. The arson in the Isthmus of Kra has also been successfully opened. It seems that the natives here have already surrendered after being added with carrots.

Judging from this situation, there will be no real soldiers and horses invading each other for a while.

It seems the situation is good.

But unexpectedly, before other things were communicated properly, Long Jiu was pulled into the whirlpool of rail transit first.

What’s funny is that Long Jiu searched for a memory in his mind and said it to the other five time travelers:

"Do you know? There was an archaeological discovery in Nanyang in the 21st century, claiming to be more valuable than Terracotta Warriors. Hehe, it is said that because of this archaeological discovery, experts claim that Qinchidao is actually a rail transit that uses wood as rails. There are sleepers under it and wooden tracks are mounted. It is said that the design of this wooden track is still very advanced."

"Brave!" Tang Kai naturally didn't believe it.

"This is true, there are pictures and truths. I have seen it online. How about it? The Qin Dynasty was able to use wood to make tracks. It is said that the effect is very good. How about we try using wood to make tracks here?"

This time, another new idea came out. Ma Fen is an orthodox modern road and railway advocate, and is now a typical minority. Wang Feng is a so-called man. These two people found that there are more and more retro ideas.

Of course, Long Jiu just talks about it. Long Jiu is very good at being a human being. First of all, Long Jiu is not opposed to rail transit, but is very supportive. To be honest, this demonstration track gives Long Jiu a very good impression. Well, he is worthy of being a person who came here in later generations, and the demonstration project is done well.

However, it is obvious that more money is invested in building the rails. The owner of the investment is of course the time travel group. This is mainly Mao Geng, and the other is West China Company, which is Chen Liang. In addition, if we can do some fundraising to build roads, it would be even better.

Long Jiu felt that there is a lot of detail about how to write reports and how to make articles. Experience in later generations shows that if the report is well written and written, the concepts must be written with concepts and demonstration projects, and if the demonstration projects have demonstration projects, you can "go to the department to make money", which is the only way to deceive the state's allocation.

Therefore, a copy for Chief Mao was a carefully packaged "Greek Rail" improvement plan. Long Jiu said that Chief Mao learned everything Western learning, and of course it would be more loud to play the Greek sign. Han Huanzhang deeply agreed with this. At least in his mind, Greek art was very sacred.

One copy for Chen Liang was the improvement plan for "Qinchi Road Rail". This is because Chen Liang belongs to a typical imperial and Han school, so he naturally played the "ancestor" sign and made him more interested.

Unexpectedly, this caused a big debate, whether there was a "wooden track road" in the Qin Dynasty!
