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

Liu Tan felt that the hot pot in his mouth was no longer delicious, so he could only frown and run to see the concrete road he had given high hopes for.

Once there, the cracked cracks in the cement road laughed at him as if they were opening their mouths wide open.

Liu Tan silently said three times in his heart: Normal heart, that's why he held back and didn't lift the table.

He was in a bad mood, and neither Miao Rui nor Bi Gao dared to vent their anger, let alone the dumb slaves beside them, who were already kneeling there trembling at this moment.

Liu Tan took a look at them after going around and said, "This matter has nothing to do with them, let them get up first, tell them, they won't be punished."

Although Liu Tan did seem to know what went wrong, it was useless to force these dumb slaves, and they couldn't tell why even if they were forced to death.

Liu Tan squatted on the edge of the cracked concrete and thought about it for a long time, then looked up at the sun in the sky, then turned around and asked, "Did it be sunny the last few days?"

Miao Rui replied cautiously: "Yes."

Liu Tan couldn't help but slapped his head. He was really negligent. When he was making models and other games, he would always remember to let the cement dry in the shade and not put it in the sun. Once it is exposed to the sun, it will definitely crack.

But building roads is different from making models by yourself. You can move the models wherever you want, but roads can only be artificially made cloudy.

Liu Tan stood up and patted the non-existent soil on his body and said, "Do it again, and after finishing it, remember to cover the top with a layer of straw, and then spray a little water, don't spray too much, just keep the straw moist. "

So... it should be considered dry, right?

Liu Tan thought while going back to continue to compete with quicklime.

The reason why he said it was a competition with quicklime was because when he was making a self-heating hot pot, he suddenly thought of Nuan Baobao. Although it has already started in spring, it is still a bit cold in spring. It is much more convenient to use when going out than holding a hand stove.

Liu Tan felt as if he had opened a new door to making money. Compared with self-heating hot pots and cement roads, things like Nuanbao obviously had more presence than them.

It's just that this thing is not very easy to handle. Originally, the warm babies of later generations used primary batteries to speed up the oxidation reaction, thereby converting chemical energy into heat energy, and then used other methods to keep warm.

Although quicklime can also generate heat, it is an instant high temperature, which is not easy to control and cannot keep warm for a long time.

But Liu Tan didn't know what was in the real warm baby, so he could only make a simple one with lime.

Even if he can't produce a "genuine product", he doesn't feel regretful. Anyway, this thing is a process of continuous improvement. After all, he has limited manpower alone. In case someone sees this warm baby and has other ideas, he will treat it as a It's good to throw bricks and start jade.

Liu Tan has no psychological burden for forgetting almost all of his chemistry knowledge, after all, no one would have thought that he would time-travel, right?

However, there is still a long distance between the dream and the realization. This distance may be the Pacific Ocean or the Mariana Trench.

If you want to use quicklime to warm your baby, there is a very serious problem - how to ensure that the heat emitted by quicklime when it meets water can be kept at a comfortable temperature for the human body and can be kept warm for a long time.

In Liu Tan's imagination, the warm baby he made should have adhesive backing, which can be attached to the body at will, and the kind that can be warm wherever you want.

However, the reality told him - don't even think about it.

First of all, he can't get out the outer packaging, and secondly, water is a liquid, which needs to be tightly sealed. Otherwise, once it is exposed when it is not needed and meets quicklime to generate heat, the warm patch will be useless.

Oh, it is impossible to warm the stickers, it can only become a heater.

Because at this stage, only metal can really release water, and it is difficult for any other material, let alone wood, which cannot be exposed to water for a long time.

Only by heating the stove and putting quicklime and water at the same time can we truly achieve physical isolation.

But if it is turned into a heater, what else is he doing? This heater sounds like a lot more trouble than a hand stove, and it may not last as long as a hand stove.

Isn't he doing this just for portability?

No, no, I still have to work hard, this kind of thing can be handed over to the people below.

Not only did Liu Tan hand it over to the people below, but he also proposed a reward. Anyone who can solve it perfectly will get a golden pill. If there is something that Liu Tan likes during the process, there will be a reward.

Bi Gao stood beside him and asked: "Your Highness, this reward...is it too much?"

Liu Tan didn't want to say much at first, it's not too much to pay a talented person with brains and skills, even if this person is his slave, there will be no job-hopping incidents, but he wants to set a model, and it's best to be able to promote it , These craftsmen may not know what science is, nor may they be literate, but their experience accumulation is quite rich.

If one day Liu Tan really wants to form a scientific system, then these experiences will be very useful.

However, he soon realized that this reward was indeed inappropriate. To him, gold pills were nothing, but in fact, when he first crossed over, he would feel a little nervous when he saw so much gold in his hand, not because he thought it was dangerous. It's purely the mental tension caused by the large amount of property in his hands.

Now he is used to it, but for a slave, he may not be able to see a gold pill in his whole life, and even if he is given, he may not be able to spend it - common people trade with gold, most of them are copper coins .

Liu Tan thought for a while and said, "Then change it, if it can be solved, upgrade it, and give me a room!"

Yes, even if they are all slaves, they are divided into different ranks. There are always good and bad ones. It is said that those high-level slaves are more powerful than ordinary civilians. I don’t know if it is true.

Liu Tan didn't dare to release slaves easily, after all, the regulations for slaves' release from citizenship were actually very strict, even if he was a prince, he couldn't do it.

With the exception of Wei Qing, there has been no second Wei Qing in China for 5000 years.

Although this reward was a bit higher, it was nothing, and it was easier to accept.

Although Liu Tan entrusted the work to the people below, he didn't care about everything himself. He got some quicklime and water, but before he could do it himself, Miao Rui and Bi Gao took him away. up!

It was really a fight. He was sure once again that the two eunuchs Liu Che gave him must have good skills. After all, he was also a man, and he struggled very hard. As a result, the two eunuchs were completely motionless from their hands to their bodies, making him feel like Struggling with loneliness.

Liu Tan sat in a safe place and looked at the quicklime and water on the table with a look of unrequited love: "It's quite safe if the quantity is not large, really."

Miao Rui and Bi Gao looked at the nose and the heart, and ignored him at all.

What else can Liu Tan do?He can only leave things to the people below.

He originally thought that even if he handed it over to the people below, he would have to wait for a while before there would be any results, but he didn't expect that Miao Rui would come to report two days later and said, "Your Highness, there is a crazy student who recommended himself in a letter, saying that he can solve His Highness's worries and problems."

"Crazy life? What kind of crazy life?" Liu Tan became vigilant when he heard it.

Although it may be a bit stereotyped, but I don't know why, every time Liu Tan hears the word Kuangsheng, he thinks of Dongfang Shuo.

But at that time, it was Liu Che who recruited talented people himself, but Liu Tan didn't have one.

Miao Rui said: "This person's name is Kui Guan, and he is from Shuofang. He said that he studied at the age of ten, learned swordsmanship at the age of 12, and began to travel around the world at the age of 19. Now he is 21 years old. Come forward and recommend yourself."

"Shuofang? Is it so far away? No, how did he know what I was going to do?" Liu Tan frowned, his first reaction was that someone leaked his information.

However, the recipes of the things that have already been made are kept secret, and it is normal for someone to see the business opportunity, so how can the unmade things be leaked?

Miao Rui immediately said: "I will send someone to investigate."

Liu Tan thought for a while and said: "While arranging for someone to investigate, let someone ask him, how did you know?"

This is not a trivial matter. The things he made before, whether it is sugar or cuttings, are actually not very complicated, especially the sugar can be easily seen with just a glance.

The simpler things are, the harder it is to keep them secret. Liu Tan began to think about whether to auction off the recipes directly. Anyway, he now has more candy recipes.

As long as his store maintains the best quality and always has the freshest gadgets, he is not afraid of competitors.

When Liu Tan was thinking about this, Bi Gao came back and said, "Your Highness, that Kui Guan is so rampant that he will only speak when he sees His Highness."

Liu Tan rolled his eyes after hearing this, and sneered: "Then let him go."

If you have read too many history books, you will know that this method of pretending to be rampant and making mysteries is the favorite of some scholars. It is probably aimed at those who are usually respectful and respectful to those around them. Ideas of particular interest.

But I'm sorry, Liu Tan is not such a person. On the contrary, he, who can be said to be half a social waste, likes straightforward and straightforward people the most.

Uh, except for Lu Xuan's straightforwardness.

To put it bluntly, Liu Tan warmed the baby just on a whim. In fact, even using quicklime to make it out is not the most perfect, so he is not obsessed with it.

Now he is most concerned about the cement road, and after artificial humidification, the cement road did not crack after drying.

Only then did Liu Tan feel relieved and asked someone to dig a roadbed from the entrance of Zhuangzi to the main building complex.

Adhering to the majestic style, Liu Tan directly asked people to dig the width enough for sixteen ox carts to line up at the same time.

While digging, he was thinking, should Liu Che's Luanjia and Chen Ajiao's Yijia be enough?

He had never seen the grand occasion of the couple leaving the palace, but based on what he had seen in the history books, it was a grand event that could occupy the widest road in the imperial city.

Considering the width of the road in the imperial city, what he is digging now is basically twice the width of the road in the imperial city, so there should be no problem.

Hey, it’s good to have land, and you can make as wide a road as you want on your own land. Fortunately, there are no strict grade regulations in terms of roads.

While he was happily waiting for the concrete road to be paved, he suddenly remembered a very important thing - in the later generations, there will be gaps between all the roads!

Liu Tan was about to give instructions on this matter, and then he was worried about how far the gaps should be. He didn't know how far the gaps were.

In the end, it was decided that it should be about the same to put one line per mile, but now there is no concept of kilometers and miles, so the final conversion is about [-] feet.

However, because of the paving of the road, Liu Tan stayed on Zhuangzi for half a month. After half a month, he had just finished checking and accepting the road, and Chen Ajiao sent someone to spread the word: Are you crazy outside?

Liu Tan suddenly felt that the hot pot in his mouth was no longer fragrant, so he immediately packed up his things and left. Before he left, he didn't forget to ask someone to bring him a few more lime bags so that he could do magic tricks for Chen Ajiao when he went back.

It's just that his car stopped as soon as it got out of Zhuangzi. Liu Tan couldn't help but lift the curtain of the car when he heard the shouting outside and asked, "What's wrong?"

Miao Rui leaned forward and said, "Your Highness, that crazy student has come to stop the car."

Liu Tan was stunned for a moment: "Who?"

Miao Rui said: "Kai Guan is the one who recommended himself to help His Highness solve problems."

The author has something to say: Liu Tan: Man, are you trying to get my attention?Very good, let's stay where it is cool!
