In fact, Li Shimin didn't know that there was still a big gap between the thinking of modern people and that of ancient people, and what seemed normal to them changed in Li Chengqian's eyes. However, Li Chengqian's opinion, in his eyes, and even in the eyes of many people, is just an unwarranted nerve, after all, when a person is out of touch with a society, it can only be this person who is wrong.

Sighing, Li Chengqian said helplessly: "Father, what the son said may be a bit childish, and it may also be very weird, if it's not right, you should just not hear it." Governing the country is actually no different from running a family, the difference is that the main body of the family fills the mouths of parents, wives and children, and the emperor wants to fill the mouths of the people of the world. It is said that diligence and thrift are virtues, so why should we waste money on this gratuitous thing? Erchen knows that the coming of all countries has made you the top emperor in this land, and compared to your dragon, the king of Goryeo and the king of Silla are just ants.

But ah, for the sake of this name, you are willing to pay a lot of money and goods to reward those envoys? Datang has been a neutral country since a hundred battles, especially you, who have fought in all directions, and you should be the one who knows the relationship between people and between forces. When did there ever ever be a real surrender between the two countries? Even if it's my Tang Dynasty, don't the local people always think about rebellion?

In the same way, the hearts of non-Wu people must be different, Tuyuhun and Western Turks, these guys are just giving some gifts, saying a few unbeneficial, and they can get a lot of rewards? If you would be angry, you're clearly an enemy. Since our Datang is an existence that they dare not provoke, then it is good to accept their tribute with peace of mind, and be guilty of paying so much for the sake of the face of the so-called Celestial Empire? ”

During Li Chengqian's speech, Li Shimin just listened and did not say a word.

After Li Chengqian finished speaking, he smiled and said: "I think you have something dissatisfied with me, it seems that there is, but it's not so serious, boy, I still shouldn't let you run around, your horizons are broadened, but your mind is a lot narrower." As far as you say, it's really petty. It's just a few rewards, which make you value it so much? ”

Li Chengqian smiled bitterly: "Father thinks that his sons will value these rewards? Although most of the money in the East Palace has been handed over to Lingnan and the bank, the family is still there, and to be honest, I really don't look down on these things. However, it's one thing to look at it or not, and it's another thing to give it or not. Erchen asked Ju Gong to find an excuse to keep the Tuguhun envoys in Chang'an, and did not allow them to return until February. Aside from the rest, Tuyuhun alone will make you realize how worthless it is for you to reward the Gentiles. ”

"That's why you asked Tang Jian to stay Tuyuhun? Do you think Tuyuhun will make a move on our Datang? Why do they dare? ”

"It's because you don't dare that you have to do it, and now is the time for you to be honored as the Heavenly Khan again, even if something bad happens at this juncture, they will assume that you will pretend not to know. If you don't believe it, let's make a bet, if Tuyuhun really does something to Datang, you can't leave Beijing for three years, how about it? ”

"Then what if Tuyuhun doesn't move his troops?"

"The sons are in charge, and they will pay to sponsor your trip, and Wei Zheng and they have their own sons and daughters, how about it?"

With three high-fives, the agreement between the emperor and the crown prince was reached.

Standing up, Li Shimin sneered: "I am waiting for the day when you will pay for my trip, I really can't think of any reason for Tuyuhun to send troops to the Tang Dynasty." ”

Li Chengqian, who achieved his goal, also smiled and said: "Erchen is waiting for the day when you will no longer reward foreign countries, and this bet will be won!" ”

The door of the temple opened, and the first person to enter was the eldest grandson.

She saw very clearly that the emperor's anger was very strong, and the prince's son had no intention of compromising, she was afraid that the father and son would quarrel.

But after entering the main hall, the scene made her scratch her head. Whether it is the emperor or the crown prince, they are all smiling at this time, not a disguise, but really cheerful from the heart.

What happened?

"What happened?"

The same puzzle is Li Tai, this guy doesn't look at the emperor and queen is always hippie and smiling, but he has an indescribable fear of the emperor's father, in his opinion, the prince and brother who dare to argue with his father and emperor are simply bunkers.

"Okay, why do you ask so much, honestly study your strength, don't say anything else, just the aspect of strength, if you study it thoroughly, you can leave a name in history with this."

After coming out of Li Yuan's Da'an Palace, Li Tai began to inquire about what was happening in the Liangyi Palace, like a paparazzi, annoying.

"How many things can be researched by research power? I've only discovered that forces in different directions are able to produce different effects, and the numbers in the period, and it's likely that there is a relationship, and I'm trying to express that relationship. After that, what else can you do? Research power, can it still make people fly? ”

After complaining, Li Tai looked up at the crown prince's brother, and saw that the prince's brother showed not a helpless expression, but approval, and the whole person trembled.

"No, I'll just say, can you really fly?"

Patting Li Tai on the shoulder, Li Chengqian smiled and said, "I'll tell you, I can really fly, although I haven't tried it, but it works in theory." ”

Li Tai, who heard this, opened his mouth and tried several times, but he couldn't speak.

Can people fly? This.... This.... Is it possible?

If someone else said it, Li Tai would definitely think it was just a fantasy and a trick to deceive people. But it was the imperial brother who said this, and he didn't think that the imperial brother would lie to himself idlely. In his impression, as long as the imperial brother affirms, it will definitely become a reality, even if it is with an uncertain tone, it will most likely be the same. And as long as the royal brother is sure that it is impossible, then such a thing will never happen.

Since the imperial brother said that most of the research power can make people fly, it is almost certain that it is indeed possible. Even if it fails once or twice, it will definitely work in the end!

Thinking that he would one day be able to fly, wander above the white clouds, bid farewell to Chang'an, and stay in the East China Sea at dusk, Li Tai trembled with excitement.

"Brother Huang, tell me, how do you fly? There is no need to study any strength, as long as we can fly, our brothers can shine in the annals of history, and those civil and military generals will defeat Rome, and they will not be as beautiful as our brothers! ”

Patting off Li Tai's hand that was so excited that he grabbed the placket of his clothes, Li Chengqian said helplessly: "What I said about flying is just a simple departure from the ground, if you want to really get more and more every day, you still need a lot of experience accumulation, and you can't do it without a thorough study." So, you'd better go for a down-to-earth study and tell you directly how boring the results are? When you reach a dead end, and it is difficult to get in, it's not too late to come to my brother again! ”

Seeing that the imperial brother said this, Li Tai could only keep his mouth shut.

Although the process of searching for the truth fascinated him, it also made him extremely painful. This time is different from the past, to be honest, the thirst to get the truth directly is not at the same level at all compared to the excitement of exploring by yourself.

Playing tricks has always been Li Tai's strongest method, and at the gate of Da'an Palace, Li Tai sat on the ground with his buttocks, hugged Li Chengqian's thighs and cried directly.

"No, you're a fool!"

In the face of Li Tai's shameless attack, Li Chengqian was really helpless.

There is such a thing as face, which has never been in Li Tai's dictionary, this guy is a person who will do whatever it takes to achieve his goals.

"I don't care, Brother Huang, tell me quickly, I really want to know!"

While screaming, Li Tai looked up at Li Chengqian's reaction, not caring at all that his actions had attracted the attention of many people.

The guards at the gate of Da'an Palace are better, they are all Jin Wuwei's old hands, and they have long learned to see out of sight. And the pedestrians on the street, seeing this scene, slowed down one after another, wanting to see what was going on.

Facing the pointing and pointing of passers-by, Li Chengqian really couldn't stand it, and wanted to pull Li Tai up, but he didn't move, so he could only smile bitterly: "Okay, let's go, go to the East Palace, I'll tell you." ”

Seeing that the imperial brother finally relented, Li Tai immediately stood up and closed his mouth.

Seeing the change in Li Tai's neat expression, although Li Chengqian wanted to turn his face and deny people, he just thought about it. If he didn't admit it, it was estimated that Li Tai would be lying on the ground. For this bastard brother, Li Chengqian really doesn't know what to do.

New Year's greetings can only be in the morning, and although the afternoon is the same, it will give people an undignified feeling. Originally, Li Chengqian planned to go to Gao Shilian's mansion when he came out of Da'an Palace, but now he can only postpone it until the second year of junior high school.

The East Palace on the first day of the new year is much more deserted than the Imperial Palace, after all, hundreds of officials will visit the emperor, but they will not take the initiative to visit the prince. was found to be in collusion with the prince, and there was no need to mix in the court.

Since Su Yuan married to the East Palace, Li Tai has rarely come over. Although the brothers are close, they must be avoided. Don't look at Li Tai's shamelessness, but he will never take a step beyond Lei Chi in these things.

After entering the study, Li Tai impatiently walked to the desk and took the initiative to find things such as paper and pens and Li Chengqian's self-made triangular compass.

I thought I could draw, but Li Chengqian threw these things aside, leaving Li Tai confused.

After making it to the chair, Li Chengqian cocked Erlang's legs and said with a smile: "Qingque, come, my brother will test you, do you know what man-made things can fly into the sky?" ”

Li Tai also found a chair to sit down, and replied without hesitation: "Paper kites, bows and arrows, stones thrown by trebuchets, and more... Kong Ming lantern! ”

The brothers have been together for a long time, and they understand each other better, as far as Li Tai knows,

Li Chengqian nodded and said: "You are right, these things can fly into the sky, but if you calculate carefully, bows and arrows and stones do not count, because they only appear in the air for a short time, and if people want to fly, they can't be thrown out on a crossbow or trebuchet." Therefore, paper kites and Kong Ming lanterns are the most stable flights. In fact, if you want to fly, it's very simple, just build a Kong Ming lantern, as far as I guess...."

"How is this possible, Kong Ming Lantern can indeed fly into the sky, but how can it fly with people?"

Without waiting for Li Chengqian to finish speaking, Li Tai jumped up directly, when he was in the Qin Palace, the three brothers of Kong Ming Lantern had not played, but how could that thing take people flying? When on the ground, a person can hold it with just one finger.

Wait, one hand can hold it?

What if you made the Kong Ming lantern bigger?

Seeing Li Tai suddenly quiet down, Li Chengqian knew that he had an idea.

That's right, Kong Ming lanterns can't fly with people, but wouldn't it be nice to increase the size of Kong Ming lanterns?

The more Li Tai thought about it, the more feasible he felt, and he even had the idea of going back to the academy to give it a try.

Holding back his impatience, Li Tai knew that even if he went to experiment now, most of them would fail.

"Brother Huang, do you think it's feasible?"

Facing Li Tai's longing eyes, Li Chengqian nodded: "It's feasible, but you'd better find the fire cloth." This thing is a necessity for a large Kong Ming lantern. I asked a lot of businessmen, and they all said that we don't have this thing in the Central Plains, plus Gaochang blocked the trade route, and I haven't seen it for a long time. But I guess, we also have this thing in Datang, but I don't know where it is. ”

For the sake of asbestos, Li Chengqian still checked a lot of ancient books. After several confirmations, it was determined that the so-called fire raccoon cloth was asbestos. As early as the Western Zhou Dynasty, Xirong Huohuan cloth as a rare foreign object tribute to Zhou Tianzi, "Liezi Tang Wen" contains: "King Mu of Zhou conquered Xirong, Xirong offered the sword of Kun Xuan, the cloth of Huohuan, Huanzhi must be thrown into the fire, the cloth is the color of fire, the dirt is the color of the cloth, out of the fire and vibrate, Haoran is suspicious of snow." Such a description must be asbestos.

In the Eastern Han Dynasty, the general Liang Ji also got a piece of fire Huan cloth clothes from the Western Regions, according to the "Fu Zi" cloud: "When the elder said Han Huan, Liang Ji made a single cloth of Huo Huan, meeting guests, and in front of the courtiers of the wine minister, he feinted to lose the glass of wine and stained it, hoping to be hypocritically angry, undressing and burning, and the cloth was on fire, and it was as blazing as it was, as if burning the cloth, and the dirt was extinguished, and it was white and white, like water. ”

Li Chengqian never thought that asbestos was used to make ready-to-wear clothes in the Central Plains, thinking that when he was picking up lime slag, he accidentally touched the asbestos on the asbestos tiles of the factory, and his hands were swollen for several days. Seeing the records in the ancient books, he couldn't help but mourn silently for the Zhou Tianzi and the general Liang Ji, how stupid it must be to wear this dress on his body, his hands are like this, let alone wearing it on his body....

"Brother Huang, do you think the record of Huohuan cloth is true? Is there really such a thing as a fire raccoon cloth? ”

Li Tai has liked Bo Wei books since he was a child, and he is no stranger to Huo Huanbu.

Li Chengqian nodded and said: "There shouldn't be any fakes, even if some miscellaneous books are forgotten, books like "Fu Zi" and "Liezi Tang Wen" will not easily deceive people." Before this, I have ordered the caravan to go to the Western Regions to search, and if we find the finished product, we can make Kong Ming lanterns that carry people to the sky, and the things that carry people, of course, cannot be pasted with paper, I think thick silk is a good choice, you might as well go back and do experiments. ”

Rubbing his hands excitedly, Li Tai didn't care that this was the first day of the Lunar New Year, so he rushed out excitedly, and directly ordered his head of the guard to summon the masters of the engineering college.

After sending Li Tai away, Li Chengqian began to prepare a letter to Yanzhou Assassin. If you want to make a hot air balloon, gasoline as a fuel is essential. In fact, as early as the Yin Shang period, the Chinese people had already discovered oil, and the Five Dynasties and Ten Kingdoms even called it "fierce fire oil" and used it for military purposes. The "Notes on the Book of Water" of the Northern Wei Dynasty recorded the relevant matters related to refining lubricating oil in stone grease water. However, this thing did not attract widespread attention, and it is estimated that even the author of the Water Sutra Note did not know that what he steamed out as waste was the most powerful thing in the resin water.

Whether used as fuel or as an incendiary bomb, gasoline is an extremely useful thing.

Like gunpowder workshops, oil fields have to be regulated as strategic resources. The oil fields in Yanzhou must be under the supervision of the Hundred Cavalry Division and under the control of the Ministry of War.

It was already afternoon when the letter was written, but a bowl of hot rice with meat sauce was still on the table. Even if she gets the identity of Liangdi, Xiuxiu still often does what only palace maids do.

looked up at the door, and sure enough, I saw Xiuxiu, as well as Ashina Xue. Ashina Xue is learning embroidery from Xiuxiu, but she, a Turkic woman, is now learning embroidery, no matter what, she can't subdue the embroidery needle, and from time to time she will prick her hand, because she is afraid of disturbing him, she can only scream silently.

Li Chengqian, who couldn't cry or laugh, walked to the door, pulled off the embroidered bandage, and said to Ashinaxue: "The content of these books in "Female Commandments" admonishes the women of the Han family, what are you doing as a Turkic girl learning these things, aren't you looking for guilt for yourself!" ”

Ashina Xue forced back the bandage and said hatefully: "It's just embroidery, what's so difficult, I can learn to ride a horse and shoot arrows, and I can't learn this?" ”

After only two embroideries, the tip of the needle pierced his hand again, and Ashina Xue suddenly screamed.

For her behavior of seeking abuse, Li Chengqian will not dissuade her twice. Although Yichun Beiyuan has pastures and sheep and horses, she will still feel bored after living for a long time, and it is good that she can find some other interests.

Seeing that Su Yuan was not there, Li Chengqian asked Xiuxiu: "Where is Yuanyuan?" ”

Xiuxiu raised her head and said with a smile: "After King Wei left, Sister Su came over, saw that you were in the office, and after guarding for a while, she returned to the Guangtian Palace, and she always had to take care of the flowers and plants in her room." ”

Li Chengqian nodded and didn't say anything more. If you live in the palace for a long time, you always have to find something to do. Just like himself, the reason why he is so angry with the emperor for what he has done is that there is actually nothing to do. As long as people are idle, they become nervous. Now that there is a distraction from oil and hot air balloons, who cares how the emperor is a loser.

Anyway, the current Tang Dynasty is still his Li Shimin's Tang Dynasty, and it is he, the emperor, who is responsible for the damage.

But then again, it's just a reward for outsiders with Datang's money and materials, even if it's a meat bun beating a dog and then being bitten back, at most it will be despised by the subjects.

It's not a big deal.

Suffer a long memory!
