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

Liu Tan felt that if he guessed correctly, the little savage that Liu Ju said should be referring to the young man next to Liu Che.

And that boy said that there is a beauty hidden in the emperor's dormitory... Could it be because he came out of Liu Che's dormitory before such a rumor spread?

Seeing Liu Tan's expression was a bit strange, Liu Ju couldn't help asking, "What's wrong?"

Liu Tan bulged his cheeks: "I went to talk to my father that day, but it was too late and I didn't have time to come back, so I stayed at my father's place. When I went back in the morning, I met a stick and asked me who I was."

Liu Ju: ...

OK, case solved.

Liu Tan looked at him strangely and asked, "Why do you suddenly care about such things?"

Liu Ju has always ignored Liu Che's harem, why is he so curious this time?

The corner of Liu Ju's mouth twitched: "All the palaces are saying that the father really asked for the favor of the immortal."

Everyone's logic is simple: if it wasn't for a fairy, why would a mysterious beauty suddenly appear?Besides, except for that little savage who accidentally met it, no one else has ever seen it. Except for the immortal, who can do it without a trace?

If it wasn't about the gods, Liu Ju wouldn't care about his father's harem, at most he would care about whether his father would give him an extra brother.

However, up to now, even if his father gave him another younger brother, it seems that there is no problem. Who still remembers Lao Qi now?

Liu Tan's head got dizzy when he heard it: "I've been free all day and have nothing to do, right? Are you still spreading rumors?"

Liu Ju thought for a while and couldn't help laughing: "Okay, I have to go, it's sunny outside, you should go back quickly."

Liu Tan had no choice but to feel that these people were really too idle. Unfortunately, even so, he had nothing to do with them. After all, it was Liu Che's harem who spread the rumors. , No, he can't, but his mother can.

As soon as Liu Tan turned his footsteps, he turned his head and was ready to go to his mother to complain.

When he got there, Chen Ajiao was teasing the Seventh Prince.

She is also a bit bored now. Although some people used the Seventh Prince to do things before, but the child didn't understand, she would not be angry with the child, especially Liu Che didn't take this son seriously at all, and Chen Ajiao didn't care much. Holding the child to her now is just like being a little pet.

When Liu Tan came over, she was still a little surprised: "Hey, is this out of customs?"

Liu Tan: ...

How come no matter who sees him, he always says the same thing.

Liu Zheng was also like this just now. He calculated the time and felt that he hadn't been busy for too long.

Chen Ajiao patted the seat beside her and said, "Come, come and sit."

When Liu Tan walked over, he took a special look at the Seventh Prince, and found that the child looked pretty good, with black eyes, plump and very round, but also kind of cute.

After he sat down, Chen Ajiao asked: "Who made you unhappy?"

Liu Tan felt that he was becoming more and more justified in complaining now. He directly complained about the magical operation of the harem. When Chen Ajiao heard that there was another young boy beside Liu Che, her expression was still calm, but after hearing the development behind Leaning forward and backward with a smile, the Seventh Prince also followed her example.

Liu Tan said with black lines all over his head, "Mother's queen!"

Chen Ajiao touched Liu Tan's face and said, "That little barbarian has some discernment."

Her son is just good looking.

Liu Tan was helpless, and deeply felt that he was just making fun of Chen Ajiao.

Just when he was about to say that those people were too busy and asked Chen Ajiao to find something for them to do, Chen Ajiao suddenly said casually: "You don't need to worry about this matter, just let it reach your father's ears."

Liu Tan looked at Chen Ajiao, turned his eyes and asked, "Does the queen mother want to teach that person a lesson?"

Well, he couldn't say the word "little barbarian". After all, Lu Xuan is also from the Western Regions. It feels like he has scolded Lu Xuan.

Chen Ajiao patted Liu Tan's head and said, "He? What is he? I want to deal with the people behind him."

Liu Tan was surprised: "The person behind him?"

Chen Ajiao was helpless: "Little fool, do you think he appeared out of thin air? If no one contributed, how could he appear beside your royal father?"

Liu Tan directly ignored Chen Ajiao's complaints and asked, "Who? Is there anyone else who dares to attack the emperor? I really don't know how to live or die."

Do you really think that you can control Liu Che by presenting a beauty to Liu Che?There are so many people who have presented beauties to Liu Che over the years, how many of them have fulfilled their wishes?

Oh, the only winner is probably Princess Yang Xinchang, after all, the beauty she offered gave birth to the eldest son and crown prince, but even so, Princess Yang Xinchang has never been able to interfere in the government.

Liu Che has been in power for so many years, and I really think he is a fool to think that he is like those foolish kings who will not be kings soon after seeing beauties.

What's more, the person offered by the other party was still a man, and he didn't even have a chance to fight, and he didn't know what the point was.

Could it be that he still wants to have Liu Che's true love?

Chen Ajiao seemed to know that he was complaining in her heart, and said, "Don't underestimate that little barbarian, he is the great witch of Baiyue."

Liu Tan was taken aback: "Huh?"

Chen Ajiao said: "It is said that there is a group of people in Baiyue who are born with longevity. They not only live long, but also don't age easily. It is said that most of them maintain their youthful appearance until they die."

Liu Tan was full of question marks when he heard it, why didn't he know there was such a place?

In the later generations, I heard about the Longevity Village, but the average age in the Longevity Village is only a little longer, and it is not like a teenager until death.

He couldn't help asking: "Who made up the story again?"

Chen Ajiao said: "Who knows? It doesn't matter whether others believe it or not, as long as your father believes it or not?"

Well, what his mother said makes sense, no matter whether others believe it or not, as long as Liu Che believes it, then others have to believe it, oh, except Liu Tan.

After Chen Ajiao finished speaking, she saw that Liu Tan's expression became very cold, and her whole temperament changed, as if she had entered a fighting state.

She couldn't help asking in surprise: "What?"

Liu Tan snorted and said, "Don't do anything, prepare to crack down on fakes!"

Knowing that he dared to do this in Chang'an, is it because he was not hard enough in cracking down on counterfeiting before?

Chen Ajiao pressed his shoulder and said, "Why are you in a hurry? This so-called great witch is different from those alchemists before. It is said that he is really capable. Don't worry about confronting him, so as not to suffer."

Liu Tan hesitated for a moment and turned his head to ask, "Father...do you really believe it?"

Chen Ajiao looked indifferent: "He didn't tell me, who knows?"

Male pets are not included in the harem sequence, even if Liu Che accepts a hundred or eighty, he doesn't need to tell Chen Ajiao.

However, Liu Tan also understood why what the great witch said immediately spread throughout the palace, even Liu Zheng knew about it.

Obviously this is the new favorite, and everyone is fawning on her.

It's right for Chen Ajiao to ignore it for the time being, anyway, she won't get any benefits, she is living a leisurely life now, why bother to go into this muddy water?

Only Liu Tan was worried that Liu Che would be cheated again, so after thinking about it, he said, "The queen mother sent someone to help Erchen keep an eye on him."

Chen Ajiao smiled: "Okay, but you don't have to worry, the binoculars you presented to your father before obviously made him more interested. It is said that the little barbarian hasn't been summoned much these days."

Liu Tan was a little surprised: "I saw him swimming in the lake with the emperor before."

Chen Ajiao laughed and said, "Didn't he post it himself?"

Liu Tan raised his eyebrows: "That's it."

That's simple, if he fiddled with something more, the so-called great witch would not be able to produce results for a while, and Liu Che would naturally stop talking to him.

To be honest, Liu Tan's appearance has whetted Liu Che's appetite.

In the past, whether Liu Che was looking for immortals or praying, even if he didn't get feedback, he didn't feel much. Instead, he thought that this was normal. Immortals, how could they be so easy to see?

As a result, now Liu Tan has given Liu Che new hope, he can go to the stars, Liu Che very simply believes that going to heaven is equivalent to becoming a fairy.

As long as Liu Tan can give Liu Che more hope, does Liu Che care whether he is a big witch or not?

Liu Tan rolled up his sleeves and was ready to study how to make a hot air balloon.

He hadn't planned to do this before, mainly because it was too energy-intensive. He had too many things before, so where would he have time to do such flashy things?

In his eyes, the hot air balloon is at most an entertainment item. If it is practical, it is really not very good, let alone it can be used in war. This thing is not flexible enough. If it does not fly high enough, the opponent will shoot a round Basically, the hot air balloon is useless. If it flies high enough... not to mention how much fuel it consumes, but what else can you see at that height?

But now, with a telescope, it is really useful.

Taking a ten thousand step back, even if it is useless, he has given Liu Che an explanation. Anyway, Liu Che has money-although he said before that he didn't want money, but Liu Che still had money sent to him, and he went straight to the car by car. Sending, the standard is based on filling all the warehouses of Suiyu Palace and his palace.

King of the North, there is no shortage of money!

There are two difficulties in hot air balloons. The first is the material used to make the main balloon. It must be strong enough to be airtight and not too heavy. The second is the fuel.

Or the most important thing is the fuel problem. According to the previous fuels, burning wood is obviously not good, and neither is carbon. These things cannot reach a sufficient temperature. Coal is fine, but it is too heavy. How much does a hot air balloon weigh?If it is too heavy, how can it go to the sky?

But now this problem has been solved in advance-artificial oil.

The difference between man-made oil and natural oil is invisible to Liu Tan at present, that is, the output of man-made oil is not enough now, but if the man-made oil production is higher, Liu Tan dares to let the big man enter the industrial age ahead of schedule.

It's a pity that only one man-made oil is not enough. To climb the technological tree, the overall technological development of the entire society must be fully developed.

Of course, it should still be possible to set up a hot air balloon for Liu Che to play with now.

After the most difficult fuel problem was solved, it was the materials used to make the main part of the hot air balloon that made Liu Tan a little bald.
