After the New Year's greetings in the first few years, Li Chengqian moved to the college and studied hot air balloons with Li Tai.

I have to say that Li Tai runs the engineering school very similarly, whether he wants wood products or iron products, he can delegate them to top craftsmen to make them. These craftsmen are not simply affiliated with the College of Engineering, they have been bought by Li Tai, and they are theoretically from the Wei Palace.

From the smallest Kong Ming lantern experiment, when the size of the Kong Ming lantern is enough to fit a person, finally reached the limit, although the papier-mâché lantern is already very light, but there is no stable fire source, always fly not high and fall.

But this did not hit Li Tai's confidence, because from the beginning of a small piece of candle, the current Kong Ming lantern has been able to carry a lamp to the sky, and experiments have proved that the larger the volume of the Kong Ming lantern, the larger the object that can fly. After the proportions change, it will definitely be able to fly with people.

"Brother Huang, I dare to really believe that people can fly now, in fact, it is just to make a large Kong Ming lantern, why didn't people think of it before!"

Li Chengqian said angrily: "Do you think everyone has time to think about whether people can fly!" People are creatures that seek advantages and avoid disadvantages, and countless people have fallen on the sky, so in theory, flying has become an impossible thing to achieve. Because of this, as long as future generations think of flying into the sky, they will take it for granted that it is impossible, and if they want to break through the cage, they need not only pure courage, but may also have to be a little ignorant. ”

Li Tai nodded, he agreed with this truth.

"Let's pause the experiment, wait for the fire cloth to be found, and besides, the problem of power still needs to be solved. Qingque, you can't expect to send people to the sky with candles, the letter from the East Palace to Yanzhou Thorn Shi has been sent, and only when Yanzhou's stone grease water is mined can you get the power to support the hot air balloon to take off. Moreover, before that, we have to study the fire device well, without a continuous supply of flames, the hot air balloon still can't fly! ”

Li Tai scratched his head, instructed the craftsmen to dispose of the Kong Ming lantern that had fallen, and then turned around and said, "Brother Huang, I have always wanted to ask, why is the Kong Ming lantern that takes people to the sky called a hot air balloon?" Like the bridge I oversaw, how good would it be to name it after the king's name or name? You see, according to legend, Kong Ming Lantern was invented by Kong Ming, not only because of the story of the Three Kingdoms, but with this, Zhuge Liang also spread his reputation to the present.

This thing you made is definitely more powerful than the Kong Ming lantern that prays for, even so, it is better to call it a Gao Ming lantern, and directly compare Zhuge Liang to it. ”

As soon as Li Tai said this, the surrounding craftsmen also nodded again and again, and even praised the name of the prince for being passed down for eternity.

For such a scene, Li Chengqian really doesn't have a lot of cold, maybe the emperor's father can accept the congratulations of the ministers without changing his face.

"Okay, what a bright lamp, do things simply, what we are going to make is to take off with heat, and the upper part will also be a sphere, how appropriate it is to call a hot air balloon, as long as the world knows that this thing was conceived by the prince Li Chengqian, it is good, there is really no need to name it with my words."

Resolutely rejecting Li Tai's idea, the brothers walked out of the courtyard of the engineering college and prepared to go back to their respective homes.

Li Ke is now preparing for the big wedding in the mansion, although Concubine Yang helps him, but he is not the eldest son, and Concubine Yang is not the queen, so he can't use the Internal Affairs Mansion as a donkey, so it takes a long time to prepare.

At least before Li Ke's wedding, Li Chengqian was not ready to return to Chang'an. If his prediction is correct, soon the emperor will enter a period of rage, although he made a bet with him and sounded the alarm, but the person who predicted in advance often does not reap gratitude, but complains. Like what:

Why didn't you try to persuade me more?

Why don't you just whip me!

....

Etcetera.

Throughout the first month, except for the great court meeting that he had to attend and the fixed greetings, Li Chengqian did not make do with the emperor at all.

Such days lasted until the twentieth day of the first month, or the twenty-eighth day of the first month to be exact. The imperial court, which had just begun to come out of the New Year's Festival, had not yet completely recovered its normal track when it received an urgent report from Feng Ang in Lingnan. The clans of Dongwangdong and Xiwangdong in Gongzhou Province rebelled. A few years ago, the chieftain and patriarch of that area entered Chang'an for the Hajj and received a lot of rewards, but after the year, it was estimated that he had just returned to his own tribe and rebelled.

The rebellion of the bureaucrats is not noticeable, the bureaucrats have never returned to their hearts, and the court is not so much to restrain them, but to occupy this land and beware of others coming to rob them. Anyway, it won't be developed for a while, so it's better to just leave it alone.

The court doesn't care if the clans don't return to their hearts, because even if they rebel, they just need to put down the chaos. And Gongzhou Road is close to Lingnan, as long as Feng Ang orders are given to quell the rebellion. As for the 100,000 urgency mentioned in Feng An's letter, no one took it to heart. As the overlord of Lingnan for so many years, it would be strange if the Feng family was rebelled by several tribes. The reason why the situation is particularly serious is just for the sake of good narrative in the future.

The courtiers didn't care, and Li Shimin, as the emperor, didn't care. In his opinion, it was just that when he was managing the clan, he had changed from Wynne's means to being powerful, and although he had rewarded them with something last year, the situation was not enough to regret it.

Because of this incident, Li Shimin wrote a private letter and handed it to Li Jian, asking him to send it to the prince's residence in the college.

After reading the letter, Li Chengqian was still expressionless and wrote a reply, but he never mentioned the gambling contract, but only introduced what he was going to do in the academy. After all, if the prince leaves the palace and doesn't return, there must be a reason. Although it sounds ridiculous to study Feitian, with Li Tai's evidence, there will be no trouble.

In this way, Li Chengqian completely hid himself. He didn't even take the initiative to inquire about the news of Chang'an, but supervised the brocade craftsmen to make the balloon balloon.

A few days after the imperial court ordered Lingnan Feng Ang to decide on his own to attack and quell the rebellion, the urgent report of Hongling from Biansai was sent to Chang'an.

Murong Fuyun, the khan of the Tuyuhun tribe, actually sent troops to loot Shanzhou, and when the border army of the Tang Dynasty reacted and was ready to fight to the death, they had no intention of occupying land at all, grabbed some grain, cattle and sheep, and returned to the territory of Tuyuhun. Because they left in a hurry, they didn't even plunder the border people of the Tang Dynasty as herdsmen.

Li Shimin, who learned the news, immediately tore up the Hongling emergency report, and without saying anything, he directly ordered all the envoys of Tuyuhun to be executed, and Wei Zheng and others tried to persuade them to no avail.

If it weren't for the prince asking Tang Jian to find an excuse to leave the Tuyuhun envoys behind, according to the time calculation, the Tuyuhun envoys would have just gotten together with their border army and returned to Tuyuhun territory together.

was about to make the finished product of the No. 1 hot air balloon, but before Li Chengqian could see the finished product with his own eyes, he was tied back to Chang'an by Li Jian.

That's right, it's tied.

"Li Jian, let me tell you, you can do whatever you want now with your father's orders, and when you settle accounts with you in the future, you will be affected!"

Li Chengqian, who was tied into a wooden stake, couldn't resist at all while lying in the carriage, although he was still very oriented towards His Royal Highness the Prince, but Li Jian took out the emperor's imperial gold medal, and Li Chengqian could only let the guards scatter.

Li Jian smiled and said, "Your Highness, do you still have the bad luck of looking for slaves and maids?" You don't know, it's almost noisy in the court now. His Majesty wanted to send troops to recruit Tuyuhun, and the generals collectively supported it, shouting that this moment was the time for the lord to humiliate the ministers. However, the ministers resolutely disagreed to send troops, saying that they had just destroyed Gaochang, how could they do anything to Tuyuhun? Tuyuhun is not a small country like Gaochang, and if it really mobilizes troops, the scale is comparable to the Eastern Turkic War.

Just when everyone was arguing, it turned out that Ju Guogong, the Qing of Honglu Temple, exposed your advice, and now everyone turned their attention to you. Don't talk about them, even the slaves and maids are very curious, how are you sure that Tuyuhun will use troops against the Tang Dynasty? I guessed so accurately, it happened to be the first month. ”

Li Chengqian, who was tied up, really didn't know what to say, did I want to tell you that there is a browser called Baidu, a book called "Zizhi Tongjian", and a book called "Old Tang Book"?

However, he also thought that the original event would not have happened, after all, although the time was the same as the eighth year of Zhenguan, but history had obviously changed because of his appearance. Even Gaochang perished six years earlier than in serious history.

However, now it seems that the plundering of Shanzhou is obviously in Tuyuhun's schedule, and it has not changed because of the appearance of gunpowder weapons. Or rather, they just have the idea of provocation, by the way to see the power of gunpowder weapons.

However, they were disappointed, although when the Gaochang was quelled, the Tang Dynasty dispatched gunpowder weapons, but this weapon has not yet been completely armed to the border army. The personnel of the Emperor's secret organization were not yet in place, and it was impossible to distribute such a deadly thing as gunpowder weapons. And the troops of Longyou Dao, because of the need to guard the Gaochang area, are very scattered, and there are no effective troops around Shanzhou, so they can succeed.

There are not many people who can ignore the palace ban and drive directly to the Taiji Hall in a carriage, even if it is Li Chengqian, he usually does not do such an arrogant thing.

However, when the carriage arrived in front of the Taiji Palace, Li Jian had no intention of loosening the tie, Li Chengqian wanted to bite his tongue and commit suicide.

The dignified prince, like the game he had hunted, was skewered with a wooden pole and carried away by two eunuchs.

Such a scene, even if the face is thicker than the city wall, has to collapse.

The person on the top of the stairs wanted to vomit, but finally entered the Taiji Hall and was placed on the ground before he was finally untied.

Before regaining his freedom, Li Chengqian wanted to find Li Jian to use his fists to theorize. However, when he heard the cold snort of the emperor's father, he could only bend down honestly and give his hand.

The court hall that "noisy fryer" in Li Jian's mouth was as quiet as death at this time. When saluting, Li Chengqian looked around, and saw that everyone was looking at what was cultivating, even Wei Zheng looked like he had nothing to do with himself.

Li Shimin's voice without emotional fluctuations sounded: "His Royal Highness the Crown Prince has such a big temper, why, I asked Li Jian to tie you up, and you still have complaints?" ”

"Back to the father, the sons dare not dare, the father has an order, even if the sons and daughters climb, they will crawl over."

In the past few years, Li Chengqian has also known the emperor's father better, this person has countless Oscar statuettes, and he is a very recuperating actor. Joy and anger are invisible, and they are skills he has long learned. And at this time, there was no fluctuation in his voice, which indicated his mood. The more angry you are, the calmer you become. It was so calm that it resembled a mechanical sound, which only meant that his lungs were about to explode.

At this point, the fool continues to be tough, and it is the best choice to bend down and admit it directly.

"Well, it's still filial piety. Anyway, I'll believe your nonsense, but tell me clearly, why did you predict Tuyuhun's movements? Also, how do you know for sure that time is now? Don't tell me it's a coincidence, there are so many coincidences in this world! ”

Seeing that the emperor finally asked, the civil and military forces of the Manchu Dynasty stared at the prince, and they were also very curious about the answer to the question. The prince's foresight is like a hexagram. However, along the way of hexagrams, most of them deceive people, and I haven't seen anyone who is sure of everything. As for Yuan Tiangang's so-called magic, that is, ordinary people and low-level officials are just good. The real high-ranking officials, including the parties Wang Qi and others, did not really believe it.

There are no coincidences that can be coincidental to this extent! This is the consensus of all. Therefore, everyone is curious about how the prince predicted it.

The eyes of everyone in the entire hall were focused on themselves, which made Li Chengqian feel a great pressure.

At this time, he realized that the sight was really stinging.

With a sigh, Li Chengqian could only say: "Returning to my father, it's actually very simple, just speculate on the unknown according to the known conditions." First of all, the Eastern Turks were overthrown, and although the Western Turks were also steppe peoples, they were more willing to plunder the countries in the Western Regions than to plunder the Tang Dynasty. Among Datang's current neighbors, only Tuyuhun and Tubo dare to do it against Datang without worrying about the consequences, and even Xue Yantuo does not dare.

Gunpowder weapons are indeed the unparalleled weapons of war, but without seeing its power in detail, the leaders of the enemy country will not give up. Compared to waiting, taking the initiative is a good choice for them. Of course, this speculation is not unwarranted. Erchen asked the king of Hejian, when my Tang Dynasty attacked Gaochang, although Tuyuhun and the Western Turks did not send troops to help, they still set up heavy troops on their own borders. Seeing that the Tang Dynasty was approaching, the Western Turks chose to flee from the wind, although Tuyuhun also temporarily avoided the edge, but then the army pressed up again. Because of this, Erchen deduced that Tuyuhun might risk the disapproval to provoke the Tang Dynasty.

Although Gaochang is a small country, Gaochang was destroyed by the Tang Army, which is still shocking enough. Because of this, even some countries that do not border the Tang Dynasty pay tribute to the Tang Dynasty and follow the trend to present you with the title of Heavenly Khan. It is the most glorious time for Datang, even if something happens to Koubian, in order to maintain its image, Datang may not directly ask for guilt. This is the idea of Tuyuhun Khan.

Push yourself and others. After taking on the role of Murong Fuyun, Erchen came to such a conclusion. If something is wrong, please laugh it off! ”

The words were finished, but there was still silence in the hall.

The prince's explanation, how to say it, sounds like that, but there is always a sense of disobedience.

Indeed, according to the prince's statement, such a result can be deduced, but it is still too accurate, right?

Also thinking the same way is Li Shimin, he found that he really can't see through the prince. If it is really as the prince said, all this was deduced by him, then his ability to deduce things is comparable to that of Fang Moudu.

I can only say that my old Li family's bloodline is really excellent?

Not interested in dwelling on this matter anymore, Li Shimin coughed lightly before saying, "I called you over today just to ask your opinion on Tuyuhun matter." The generals were all in favor of sending troops to recruit no ministers, but the ministers felt that they had destroyed Gaochang and attacked Tuguhun, which was a reckless force. The two sides were arguing, and I didn't know what to do, so I called you over. Tell me, what do you think should be done? ”

What to do? It's my business.

Obviously feeling the blazing gaze of the generals and ministers, Li Chengqian didn't know what to say.

The confrontation between civil and military forces is a common pattern in politics. Now the two sides are in dispute, and the emperor, as the arbiter, always has to choose one side. However, now the emperor's father threw this hot potato into his hands.

The prince is different from the emperor, no matter what choice the emperor makes, it should be, the prince's words, that is, purely supporting one side, choosing a military general, it is bound to offend the ministers; Choosing Wenchen is bound to attract the eyes of the generals.

It is difficult to be small between the two majors, even if it is the prince, in front of the two groups of civil and military, it is also very small.

At this time, you have to make a choice, when you can't do it, you will be despised by both parties.

After thinking for a while, Li Chengqian arched his hand and said: "Erchen's suggestion is that the troops should not be used first, no matter what, the current money and grain in the treasury should not be used again, in order to prevent possible disasters, sending troops can only be done when the money and food are sufficient enough." However, Tuyuhun did such a stupid thing, but it can't be just left at that. Erchen felt that his father should take the lead in drafting an edict reprimanding Tuyuhun and ordering Murong Fuyun, the Khan of Tuyuhun, to enter the court to ask for guilt. As for this edict, it should also be jointly signed by our generals of the Tang Dynasty, so that the deterrent effect is enough.

What Shanzhou lost was only grain, cattle, sheep and property, and none of the residents even died, so it was not a loss to deal with it in this way. ”

After saying this sentence with a clear conscience, Li Chengqian didn't even have the face to look at the general.

At the moment, it is estimated that there is only one way to reprimand them. Not to mention that Gaochang's troops have consumed a lot of the treasury, even the remaining troops of Gaochang Xintu are still consuming the treasury. Moreover, the eighth year of Zhenguan is a year of many disasters and difficulties, and there is no place for Datang from south to north and east to west. Where you need money, you go to the sea.

For the sake of temporary face, there is no way to rescue when a disaster occurs in the mainland, in Li Chengqian's view, it is the most terrible thing.

Therefore, in the final analysis, his speech is still biased towards Wenchen's side.

As for the joint name or something, it's just a means to comfort the generals.
