Liu Tan felt that the hot pot in his mouth was no longer fragrant, so he could only run with a frown to look at the cement road that he had high hopes for.
When he got there, the cracks in the cement road seemed to be laughing at him with their mouths wide open.
Liu Tan repeated to himself three times: "Keep calm", and only then did he restrain himself from overturning the table.
He was in a bad mood. Miao Rui and Bigo didn't dare to breathe loudly, not to mention the mute slaves beside them, who were already kneeling there trembling.
Liu Tan walked around, glanced at them, and said, "This matter has nothing to do with them. Let them get up first and tell them that they won't be punished."
Although Liu Tan seemed to know what went wrong, it was useless to force these mute slaves. Even if they were forced to death, they would not be able to explain why.
Liu Tan squatted beside the cracked cement and thought carefully for a long time. Then he looked up at the sun in the sky and asked, "Was it sunny the past few days?"
Miao Rui answered carefully: "Yes."
Liu Tan couldn't help but slap his head. He was really careless. Whenever he made models before, he would remember to let the cement dry in the shade and not put it in the sun. Once exposed to the sun, it would definitely crack.
But building a road is different from making a model yourself. You can move the model around, but you can only artificially create cloudy days for the road.
Liu Tan stood up, brushed off the nonexistent dirt, and said, "Do it again. When you're done, remember to cover the top with a layer of straw. Then spray it with a little water, not too much, just keep the straw moist."
This...should be considered as drying in the shade, right?
Liu Tan thought about it while going back to continue struggling with the quicklime.
The reason why he said he was competing with quicklime was because when he was making the self-heating hot pot, he suddenly thought of the hot pack. Although it was already spring, there was still a bit of a late spring chill. It was much more convenient to use it when going out than holding a hand warmer.
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 hot packs are obviously more prominent than them.
But this thing is not easy to make. Originally, the hot packs of later generations used primary batteries to speed up the oxidation reaction, thereby converting chemical energy into thermal energy, and then used other methods to keep warm.
Although quicklime can also generate heat, the high temperature is only instantaneous, difficult to control, and cannot maintain heat for a long time.
However, Liu Tan didn't know what was actually inside the hot pack, so he could only make a simple one using lime.
Even if he can't make a "genuine product", he doesn't feel regretful. After all, this thing is a process of continuous improvement. After all, he has limited manpower. What if someone sees this hot pack and has other ideas? He will just treat this thing as a starting point for discussion.
Liu Tan had no psychological burden about having almost forgotten all his chemical knowledge. After all, no one could have imagined that he would travel through time.
However, there is still a long distance between desire and realization, and this distance may be the Pacific Ocean or the Mariana Trench.
If you want to use quicklime to make a hot pack, there is a very serious problem - how to ensure that the heat generated by the quicklime when it comes into contact with water can be maintained at a temperature that the human body feels comfortable at and can keep warm for a long time.
In Liu Tan's imagination, the hot pack he made should have an adhesive backing, which can be attached to the body at will, and can warm wherever you want.
However, reality told him - don't even think about it.
First of all, he couldn't make the outer packaging. Secondly, water is a liquid and needs to be tightly sealed. Otherwise, if it is exposed when not needed and comes into contact with quicklime to generate heat, the heating patch will be useless.
Oh, the heating pad can no longer be used as a heating pad, it can only become a heater.
Because at this stage only metal can truly release water, it is difficult for any other material to do so, not to mention wood, which cannot be in contact with water for a long time.
Only by adding quicklime and water to the stove can physical isolation be achieved.
But if it is turned into a heater, then what is the point? This heater sounds much more troublesome than a hand warmer, and it may not last as long as a hand warmer.
Isn't he doing this for portability?
No, no, you still have to try harder. This kind of thing can be handed over to the people below.
Liu Tan not only handed it over to his subordinates, but also set a reward. Anyone who could solve the problem perfectly would get a golden pill. If there was something that Liu Tan took a fancy to during the process, there would also be a reward.
Standing nearby, Bi Gao asked, "Your Highness, this reward...isn't it too much?"
Liu Tan originally wanted to say it wasn't much. No matter how much money was paid to a person with brains and skills, it wouldn't be too much. Even if this person was a slave under him and wouldn't jump ship, he wanted to set an example. It would be best if he could promote it. These craftsmen might not understand science or be literate, but they had accumulated a lot of experience.
If one day Liu Tan really wants to establish a scientific system, these experiences will be very useful.
However, he soon realized that the reward was indeed inappropriate. To him, the gold pills were nothing. But in fact, when he first came here, he felt a little nervous when he saw so much gold in his hands. It was not because he felt there was danger, but because he was simply nervous because of the large amount of property in his hands.
Now he has gotten used to it, but for a slave, he might not even see a gold pill in his entire life, and even if he was given one, he might not be able to spend it - ordinary people have no time to trade with gold, most of them still use copper coins.
Liu Tan thought for a moment and said, "Then change it. If it can be solved, upgrade it and give me a room!"
Yes, even if they were all slaves, they were divided into different classes. There were always those who were doing well and those who were not. There was a legend that those high-ranking slaves were more prestigious than ordinary civilians, but I don’t know if it’s true.
Liu Tan did not dare to denaturalize slaves easily. After all, the regulations for denaturalizing slaves were very strict, and even if he was a prince, he could not do so.
There has never been another Wei Qing like Wei Qing in the five thousand years of Chinese history.
Although this reward is a bit high, it’s not a big deal, and it is easier to accept.
Although Liu Tan handed the matter over to his subordinates, he did not just ignore it. He got some quicklime and water, but before he could do anything, Miao Rui and Big Gao took him away!
It was really a fight. He once again confirmed that the two eunuchs Liu Che gave him must be quite skilled. After all, he was a man and he struggled very hard. However, neither of them moved from their hands to their bodies, making it seem as if his struggle was in vain.
Liu Tan sat in a safe area, looking at the quicklime and water on the table with a look of despair on his face: "If the amount is not large, this stuff is quite safe, really."
Miao Rui and Bi Gao looked at him with their eyes and their noses, and ignored him completely.
What else could Liu Tan do? He could only hand over the work to his subordinates.
He originally thought that even if he handed it over to his subordinates, it would take some time before any results could be achieved. Unexpectedly, two days later, Miao Rui came to report and said, "Your Highness, a madman has written a letter recommending himself, saying that he can help Your Highness solve a problem."
"Crazy student? What kind of crazy student?" Liu Tan became alert when he heard it.
Although it may be a bit of a stereotype, for some reason, every time Liu Tan heard the word "kuangsheng", he thought of Dongfang Shuo, especially the letter of self-recommendation, which sounded so familiar. Didn't Dongfang Shuo recommend himself by writing a letter in the beginning?
But at that time it was Liu Che himself who recruited capable people, but Liu Tan did not have any.
Miao Rui said, "This man's name is Wei Guan, and he's from Shuofang. He claims to have been studying since he was ten, learning swordsmanship since he was twelve, and traveling extensively since he was nineteen. Now, at twenty-one, he's dabbled in some unusual and ingenious skills. He heard about your highness's difficulties and came forward to recommend himself."
"Shuofang? Is it so far? 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 formula of things that have been made is kept secret. It is normal for someone to want it when they see a business opportunity. How could it be leaked if it has not been made?
Miao Rui immediately said, "I'll send someone to check right away."
Liu Tan thought for a moment and said, "Arrange for someone to investigate while asking him how he knew."
This is no small matter. The things he made before, whether it was white sugar or cuttings, were actually not very complicated, especially white sugar, which anyone could learn at a glance.
The simpler something is, the harder it is to keep it secret. Liu Tan began to consider whether to auction the recipe directly. Anyway, he now has more candy recipes.
As long as his shop always maintains the best quality and always has the newest things, he will not be afraid of competitors.
Just as Liu Tan was pondering this, Bi Gao returned and said, "Your Highness, that Wei Guan is being very arrogant. He said he would only speak when he sees Your Highness."
Liu Tan rolled his eyes and sneered, "Then let him go."
If you have read a lot of history books, you will know that this kind of pretentious and mysterious method is the favorite method of some scholars. It is probably aimed at the idea that those in power, who usually have people around them who are respectful, will be particularly interested in the sudden appearance of an arrogant person.
But sorry, Liu Tan is not such a person. On the contrary, he is a person who can be said to be half socially useless and he likes straightforward and frank people the most.
Well, except for Lu Xuan's straightforwardness.
To put it bluntly, Liu Tan made the hot pack on a whim. In fact, even if he used quicklime, it would not be perfect, so he was not obsessed with it.
His main concern now is the cement road. After artificial humidification, the cement road did not crack again after drying.
Liu Tan finally felt relieved and ordered people to dig a roadbed from the entrance of the manor to the main building complex.
Adhering to his magnanimous style, Liu Tan directly ordered people to dig a width wide enough for sixteen ox carts to be parked side by side at the same time.
While digging, he was thinking, should it be enough to pretend to be Liu Che's imperial carriage and Chen Ajiao's ceremonial carriage?
He had never seen the grand ceremony of the couple leaving the palace, but from what he had read in history books, it was a grand ceremony that could have occupied 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.
Well, it’s good to have land. You can build roads as wide as you want on your own land. Fortunately, there are no strict grade regulations for roads.
Just as he was happily waiting for the cement road to be paved, he suddenly remembered something very important - in the future, there will be gaps between all roads!
Liu Tan immediately gave the order for this matter, and then he was worried about how far the gap should be. He didn't know how far it should be.
Finally, it was decided that placing one line every mile should be about the same, but there was no concept of kilometers and miles at that time, so the final conversion was about thirty meters.
However, because of the road construction, Liu Tan stayed at the village for half a month. Half a month later, just when he had completed the inspection of the road, Chen Ajiao sent someone to tell him: Did you go crazy outside?
Liu Tan suddenly felt that the hot pot in his mouth was no longer fragrant, so he immediately packed up and left. Before leaving, he did not forget to ask someone to bring him a few more lime bags so that he could perform magic tricks for Chen Ajiao when he returned.
However, his car stopped as soon as it left the village. Liu Tan heard shouting outside and couldn't help but lift the car curtain and asked, "What's going on?"
Miao Rui came up and said, "Your Highness, that crazy guy came to stop the car."
Liu Tan was stunned for a moment: "Who?"
Miao Rui said, "Wei Guan is the one who volunteered to help His Highness solve his problems."
The author has something to say: Liu Tan: Man, are you trying to get my attention? Very good, go wherever it’s cool!
