I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Che was a little surprised when he received Liu Tan's letter. It had been more than seven days since Liu Tan wrote a letter last time. Counting the messenger's journey, it can even be said that Liu Tan almost sent two letters. letter.

He remembered that the last time something like this happened was when the Xiongnu Zuo Dawei sent envoys to request internal and external cooperation to kill Shanyu Wushilu, and Liu Tan wanted to kill Shanyu first.

Thinking of this, Liu Che's expression suddenly became a little subtle. Although he was very happy when his son wrote to him, but...everything happened, even Liu Che couldn't handle it.

In the final analysis, the big man's control over the Western Regions was too weak, and Liu Tan felt that Liu Che had a feeling that everything happened there.

Liu Che is middle-aged and has been emperor for so many years, there are not many things that can make him feel this way.

So he looked at the letter on the desk, stared at it for a long time, and then slowly opened the letter.

Then he was almost broken by the first sentence.

Originally, Liu Che was leaning on the back of the throne chair to read slowly, but when he saw the first sentence, he sat up straight, and then his eyes were fixed on the gold mine, unable to extricate himself.

He suddenly remembered that it seemed that a huge box was sent along with this letter.

Liu Che originally thought that it was Liu Tan who found some beautiful stones, or some local specialties, but according to the letter, it might be a huge piece of dog's head gold!

Liu Che turned to Bu Fan and said, "Go and get the box that Tan'er sent back, and by the way, bring... the Shaofu."

Liu Che originally wanted Bu Fan to recruit Da Sinong, after all, this kind of matter should be in charge of Da Sinong, but after thinking about it, he still asked people to recruit the Shaofu.

According to the laws of the Han Dynasty, gold mines discovered must be nationalized, but there is one group that is relatively exception-the royal family.

After all, the whole world belongs to their family, and no one can say anything if Liu Che wants to take the gold mine as his own.

Bu Fan immediately asked for the box to be brought up, and at the same time asked for the Shaofu to be summoned.

The box came faster than Shaofu, and it was opened in front of Liu Che. The dog's head gold that was simply placed inside shone with dazzling light. Liu Che had seen the world before, but dog's head gold was very rare, even if it was not pure gold. It is irresistible to its charm.

Just one point is enough to make Liu Che like it—natural formation.

Liu Che looked at it carefully for a long time and suddenly said, "This piece of gold...doesn't it look like a horse's leg?"

Bu Fan bent down and said, "It does look like a horse's leg."

Liu Che was happy: "Okay, okay, this is a warning from the heavens. The group of envoys who were selected to be sent to Dawan before can leave."

Liu Che has always been haunted by the sweaty BMW. He had already selected an envoy to go to Dawan. The reason why he didn't let him go was because he wanted to wait for Liu Tan to come back and ask about the situation in the Western Regions.

It's just that now Liu Che estimates that his son may not come back in the short term, not to mention that Liu Tan sent someone to send over the newly drawn map of the Western Regions. At that time, the situation was urgent, and Liu Che would not be too harsh.

After Bu Fan heard this, he immediately went down to deliver the order. At this time Shaofu Ji Hang came quickly, saluted Liu Che and said, "I pay homage to Your Majesty."

Liu Che said: "Tan'er discovered a gold mine in the Western Regions. The size of the gold mine is not yet known. You quickly select experienced people to go to the Western Regions to assist the Fifth Prince in mining."

The Shaofu was still wondering why the emperor suddenly summoned him. The vernal equinox has passed, and the summer solstice is still far away. There are no major festivals that require the Shaofu to be busy.

Then he was caught off guard by Liu Che. After listening to it, his brain was a little unresponsive, and he was stunned for a few seconds before he stammered, "Fifth... His Highness... discovered the gold mine?"

Liu Che admired Ji Hang's bewildered expression, and finally felt more balanced. He nodded and said indifferently, "Tan'er is lucky, but the location is a bit remote, so there must be no mistakes in choosing someone quickly."

Ji Hang replied dumbly, and after he exited the hall, he was exposed to the sunlight outside before reacting, and then gasped.

A gold mine was discovered in the Western Regions, what did the Fifth Prince do?

There are very few gold mines exposed on the ground. According to His Majesty's order, it is speculated that they were not discovered from the ground, otherwise you can judge one or two by looking at the ground, so... the fifth prince went to the Western Regions to dig three feet ?

Ji Hang left with full of doubts.

Liu Che is still admiring his horse leg gold, um, even if Liu Tan calls it dog head gold, Liu Che still stubbornly thinks that it is horse leg gold, this is God's sign that the trip to Dawan in exchange for sweat horses will be very smooth .

After appreciating it, Liu Che began to think about how to deal with this gold mine.

In fact, Liu Tan has written very clearly before that the city was built mainly for this time, and the main reason for building it so well is that the big man may need to use it in the future, so as to avoid temporary construction of the city, and even if it goes well, it is not a good idea to send troops to stay permanently in the future what is the problem.

Sending troops to Liu Che basically never thought about it. It is too close to the Cheshi Kingdom, too close to the Xiongnu, and it is not safe to be closer than the surrendered city. Let Liu Tan take refuge in Xiaowusun first.

But the gold mine... Liu Che thought about it for a while, and felt that it still depends on how Liu Tan fights this time.

If you can frighten Jieguo, deter Cheshiguo, and make Cheshiguo dare not go to the Xiongnu for help, then you can still send people to garrison, if you can't, you have to evacuate.

Liu Che decided to dig the mine first, dig as much as he can, and if he can't, destroy it and don't let the people of the Western Regions know!

Then he was a little worried, he always felt that Liu Tan's painting style was different from other people's.

He said before that Liu Tan was like Wei Qing, but now he feels that he needs to take that back.

Back then, Wei Qing fought as soon as he said he wanted to fight, with a clear goal and quick action. When he came to Liu Tan's place, he said he was going to fight a long time ago, but what are he doing now?Still building the city!

For a while, Liu Che didn't know whether to send troops to continue to support, so he could only order Yangguan to pay attention to support at all times. As for the large number of troops... let's forget it for the time being. Every movement of soldiers will cost sky-high military expenses. Hold on, as for Liu Tan paying for it... Forget it, how can his little money support the army to go out?

Liu Che was happy and sad for a while.

Liu Tan didn't know at all that he worried Liu Che enough. After learning that Liu Che had sent experienced craftsmen over, he began to build the city boldly again.

After designing the underground sewage problem, Liu Tan went to the construction site to take a look.

At this time, the construction site is laying pile foundations bit by bit. Because there are many rocks and the land is not flat, the pile foundations cannot be standardized and all are the same. As a result, the length of the pile foundation can only be designed according to the terrain, so as to ensure that the ground of the city is absolutely flat.

Because there are tents to cover, many large braziers are burning in the construction site for lighting.

Even if the temperature in the Western Regions is not as high as that in the Central Plains, Liu Tan is still terribly hot in what can be considered a confined space.

Standing on the top and looking around, he always felt that this scene seemed familiar and made him feel very close and familiar. After thinking about it for a long time, he suddenly realized that this is what the archaeological site of later generations looks like.

In later generations, salvage excavations would cover a shed in order to protect cultural relics, and now they have a bit of that flavor here.

Liu Tan not only checked the information to see such photos back then, but even went to the archaeological site along with the fun, it is strange if he is not familiar with it.

After watching the progress, he casually scanned and found that there were many beddings in the corner of the tent, so he couldn't help but turn his head to look at Jiang Chong: "Are you letting everyone rush to work day and night?"

Jiang Chong followed Liu Tan's gaze and saw the bedding. He knew Liu Tan's temperament at least now, and said immediately: "Many people sleep here at night, mainly because the wind and sand in the past few days are not small. Many people They all felt that it was safer inside than a tent.”

Could it be unsafe? With so many woods used as the skeleton, and the pile foundations are also deep, the entire tent can almost be built as strong as possible. In the event of wind and sand, the stability must be stronger than that of a small tent.

Liu Tan was a little helpless: "This is not a place for people to sleep. I know it's crowded now, but I have to tell them that this tent is not foolproof. If it collapses, ordinary tents still have a chance to escape. , bumps and bumps may kill you.”

Jiang Chong said in a low voice: "Your Highness, the wind and sand that can overturn this tent, even if people survive and go out, I'm afraid it will be very dangerous."

They had seen how terrifying the sandstorm in the Gobi was. A horse had been given the reins but was not tied up. When they looked for it the next day, only a horse carcass was left in the sand.

It is said that this is a case of good luck. If you are not lucky, if you fall into the quicksand, you will not be alive or dead.

Liu Tan didn't say anything after hearing this. As long as a house is not built in this dilapidated place, it will be unsafe for a day.

So he is very urgent now. After walking around for a while, he turned around and started to think—what about the sewage facilities?

Using underground drainage can definitely make the city more tidy, but there is a very serious problem with underground drainage, that is, how to get the drainage pipes?

He does now have the big killer cement that transcends time and space, but the problem is that it is still very difficult to shape the cement into a pipe.

The biggest problem is that there is no model, and it is definitely inappropriate to let people do it now, and their transportation methods are also very primitive. If the drainage pipe is too large, it cannot be transported.

Liu Tan sat there thinking for a long time, and finally found that there seemed to be only one way - let cement act as a binder, and glue the stones together to form a circular pipe shape.

In this way, it is possible to directly build a little bit at the place where the pipeline needs to be laid, but this kind of operation is not easy, because now the stones in their hands are basically dug out from the ground, and there was no rule when they dug it. What it looks like, so they are made in different sizes and shapes.

It is very difficult to bring these shapeless stones together to form a circular pipe without leaking or leaking.

Liu Tan sighed, and while fiddling with the sand in his hands, he wondered if Huo Guang would beat him violently if he made this request.

After all, Huo Guang has lost weight visible to the naked eye since following him on his mission to the Western Regions. If this continues, he wonders if the Huo family will feel that he has abused Huo Guang when he returns to Chang'an?

When Huo Guang came in, he happened to see Liu Tanzheng building a miniature city with bricks, stones and tiles bit by bit.

Of course, the city now only has foundations, which seem to be about the same as their current progress, but in fact, if you look closely, you can already see some circular pipes interspersed between the pile foundations.

Seeing his frowning expression, Huo Guang's heart sank, he was too afraid of Liu Tan's expression.

Usually Liu Tan will have this kind of expression, which means that he has encountered a problem, and what Liu Tan can think of after encountering a problem, and what solution he can come up with is basically completely uncontrollable.

Huo Guang first put down the things in his hands and asked, "Your Highness...but what difficulties did you encounter?"

Liu Tan was lying on the desk without any image at this time, and he didn't sit up when he saw Huo Guang coming. Anyway, he was very familiar with him, and Huo Guang probably could accept his sitting without a face.

He raised his eyes to look at Huo Guang and said, "Tell me...how are these pipes going to be laid?"

Huo Guang is already used to the new words that Liu Tan pops up from time to time, and he is immune to them. In fact, this is not the point. He quickly asked, "Your Highness, if you have any difficulties, you can tell them directly."

But don't think of something new after a slap in the head.

After Liu Tan talked about the difficulties, Huo Guang resolutely said: "This is no problem, Your Highness, don't worry."

Compared with Liu Tan's tossing, this is a trivial matter.

Liu Tan looked at Huo Guang with some doubts: "Really? But... how can these fragmented stones be made to be round? How can they be guaranteed to fit perfectly? How can..."

Huo Guang took a deep breath: "I don't need to worry about this, Your Highness!"

Liu Tan blinked, okay, he decided to trust Huo Guang, after all, Huo Guang is really capable, and if he is not sure, he will not promise easily.

But in fact, even a gentleman like Huo Guang couldn't help but learn to lie when facing Liu Tan, and he didn't have any psychological burden.

He really couldn't accept Liu Tan's sudden whim, if it wasn't for...he should have returned to Chang'an by now!

However, Huo Guang really did not lie to Liu Tan. The wisdom of the ancient people of the flower planters cannot be underestimated. After all, there was no clear scientific system in ancient times, but they once led the world in various inventions and creations.

On the third day since Liu Tan was worried, the masses of wise people came up with a solution - it doesn't matter if there is no model, they can make the inner core.

Anyway, it was originally a round pipe, and the inside needed to be hollow, so they simply found a two-person hugging tree that hadn't completely dried out, peeled off the outer bark completely, and then covered it on the wood, and then used it a little bit on the outside of the tree. Patchwork of stones and cement is laid.

The main reason why it is not air-dried is to ensure the integrity of the bark, so that the trees inside can be pulled out smoothly after the cement dries.

As for the bark inside, it's easy to clean up. Find a thinner piece of wood, sprinkle it with sand and gravel and scratch it down a little bit. They can even put a layer on the outermost layer without worrying about the bark. Cement, so that the inside can be guaranteed to be smooth.

Liu Tan stood in place and looked at the drain pipe that everyone had made. Huo Guang smiled and asked, "Your Highness, can I use it?"

Liu Tan said with emotion: "It's not only possible, it's simply too possible."

It seems that as long as there are no scientific difficulties in the future, he can completely leave it to the people below. After all, his experience in some aspects cannot support him to engage in such a large project. The consequences of forcing himself are insomnia and hair loss.

This is really helpless, he doesn't want to delay for too long, he just wants to build the city as soon as possible, so when encountering difficulties, he forces himself to think of a way all night, so as not to lose his hair.

If this continues, he suspects that when he can return to Chang'an, he will really be bald.

Fortunately, before he became bald, the construction of the city was still very smooth, and the city wall was not completely made of cement, but was paved with stones, using cement as a coagulant.

Originally, Liu Tan was worried that the quicklime would not be enough, but now he found that the quicklime might be enough, but the stone... could only rob the nearby river valley.

After starting to build the city, when the city wall reached a certain height, the tents began to be dismantled.

And on the day when the tents are completely dismantled, it means that there is basically no problem with the outer city walls. As for the inside... let's go in and use tents to make ends meet while building houses.

Huo Guang was obviously more impatient than Liu Tan, so he approached him directly and said, "Your Highness, you can send troops now, and it's okay to develop slowly here in the future."

At that time, Liu Tan had already started thinking about whether to build a few public toilets, and then connect the sewage facilities to underground pipes.

However, this idea is a bit unrealistic, because water must be available to connect underground pipes, but the most scarce thing in the Western Regions is water.

When Huo Guang said this, although Liu Tan regretted that the city only had a prototype just now, he also felt that it was not good to procrastinate, so he said, "Everyone have a good night's rest today, and tomorrow we will study how to fight."

After Liu Tan said this, Li Buyan suddenly rushed in from outside and said, "Your Highness, Your Highness, something serious has happened."

Liu Tan looked up at him: "What?"

Li Buyan couldn't breathe: "Little Kunmi led people to attack Huhu, and now he has captured King Huhu, and is looking for you to ask you to deal with King Huhu."

Liu Tan:? ? ? ?Is this guy crazy?
