The expansion of the college was imperative, and originally the college was close to the Weishui side, and the gate of the college was facing south, just to leave enough space for subsequent expansion. Even if the college itself is counted, the College of Engineering was able to expand again thanks to the work of cement and the curved plow. This time, as long as the Ministry of Industry and the craftsmen who will be the supervisors and the weapons supervisors are famous, they will be able to come to the engineering college for a few months every year to communicate.

The progress of science is in the collision of ideas, you guard the family handicraft, he guards the ancestral handicraft, and it is still the same for a hundred years.

Teaching and educating people is the long-cherished wish of the more than 200 old gentlemen of the college, and it is also what they are good at. But it's really hard for them to let them make money for the academy.

"Starting from Chang'an, the implementation of one state after another, and after all the states have built schools, they will continue to push one county after another, and one day, the people of the whole Tang Dynasty will be literate!"

Seeing that the prince said heroically, Yang Du could only selectively forget the long time of this process for the time being.

A journey of a thousand miles begins with a single step!

Looking at the students who were kicked out of the classroom by the gentlemen after class, and still reading with books, Yang Du's heart immediately warmed. These students are the hope of the college. As pioneers, these old men must lay a foundation for future generations to persevere!

"Your Highness, the old man will go back to class."

After sending Yang Du away, Li Chengqian touched his rumbling stomach and also went to the cafeteria.

Today's cafeteria is much more lively than usual, the chef in the back kitchen is so busy that his feet don't touch the ground, no matter how much rice is steamed, it is not enough, and the chef who is making the spoon can't hold his right arm, and now he is using his left arm.

The nobles were better, and it was the first time that the common people had eaten in the cafeteria of the academy. In the past, every day before the holiday, students would bring a whole day's meals home, either to share with their younger siblings or to honor their parents. After Li Gang learned about this, he added a tough rule, that is, on the morning of the holiday, students were allowed to bring a packed fresh meal in the cafeteria to eat "on the road".

Now the old man is not gone, but this rule is still there.

The food of the academy is naturally the envy of ordinary families, because there is a farm directly supplied at the back, and the most important thing in the canteen is meat, plus the braised pork ribs and other dishes are still from the East Palace, and the meals in ordinary restaurants can't be compared.

Many people came to the academy for the first time, and they were a little restrained at first, but after hearing that the rule here is to eat as much as they can, they completely let go.

The nobles are naturally different, as the big financiers of the academy, they eat on the second floor, or a variety of dishes.

No one thinks that this arrangement is wrong, and the people at the bottom of this era have not yet learned to demand justice.

The private rooms on the second floor were originally intended for the old gentlemen, but because they preferred to eat with the students, now they can only be used as a place for the college to entertain guests.

Seeing the prince go upstairs, Fang Xuanling came over with a glass of wine and said with a smile: "I only knew that the widow had learned well, but I didn't know how it was, but now there is a parent-teacher conference, which makes the old man's face shine!" ”

People like Lao Fang will not come over and talk useless nonsense unless it is necessary.

Li Chengqian is naturally clear about this.

Arching his hand, Li Chengqian smiled and said: "If you have anything to say, it's better to say it directly, although I am wearing formal clothes today, you still treat me as the vice president of the college." ”

"The old man heard that the academy spends a lot of money a year, and the Donggong family supports it, so I'm afraid I can't do it. In the end, it is a good thing to teach and educate people, the Fang family is ready to sponsor the college, I don't know what His Highness wants? ”

Looking at the fox-like Fang Xuanling, Li Chengqian didn't know what to say.

This old thing, even wants to take a stake in the academy? In the end, he is a person with a vicious eye! Teaching and educating people is a cause of great merit, and if it is related to this, it can promote the prestige of the family. As long as the academy continues to develop, it will always become a key department of Datang, and if any family is tied to the academy, it will be like getting a gold medal for avoiding death. After all, the real reason why the royal family didn't dare to really attack the five surnames was because they were "famous families".

However, in this case, wouldn't it be necessary to give them dividends at that time?

That's not going to work!

"Fang Xiang is joking, although the East Palace is not big, it is no problem to support the academy, besides, even if the East Palace can't hold it, I can still ask my father for help, right?"

Seeing that the crown prince moved out of the emperor, Fang Xuanling could only sigh and give up this plan.

No one dares to take a piece of the royal industry, and he Fang Xuanling is the same.

The eldest grandson Wuji has a lot of face today, but because of the arrogant performance in the conference hall, he is now being "toasted" by a large group of people. Although he knew that these people had bad intentions, he could only drink it all the time.

Not to disturb the interest of these nobles, Li Chengqian found a secluded box, asked for a meal, and ate with Zhang Yun Yutai.

"Sit down! How can anyone eat standing up? ”

The two of them were eating standing in front of him, and Li Chengqian felt very unaccustomed.

Zhang Yun sighed and said, "You still don't care about your status like this, Yu Tai and I are subordinates, how can we have the qualifications to eat at the same table with you?" ”

Yu Tai smiled and said: "If it's in the barracks, the subordinates don't care, but now in the academy, you are still wearing formal clothes, and there is no shortage of imperial historians outside the box, it is no longer appropriate to see the two of us eating with you, if you are still sitting, you will not be impeached, Zhang Yun no one dares to impeach, I am old Yu Ke will be unlucky." ”

Seeing that the two of them insisted, Li Chengqian could only sigh. Although he has been the crown prince for five years, he is still not superior. But fortunately, many times his persistence will be understood as a means to win people's hearts, but no one has ever doubted it.

After lunch, it's time to leave. There is nothing for him to do here in the academy, and if he doesn't return to the East Palace, it is estimated that he will be cleared back by the hundreds of officials outside. Without Mr. Li Gang, he has no freedom now.

Therefore, it is not easy to be an emperor, trapped within the palace walls, and easily unable to move. As for the crown prince, it is even more bitter, because even if he becomes the emperor, he is just a different place of detention.

Instead of riding in a car, I rode a horse. Although the crown prince lost the battle with the Xuanjia army, Li Chengqian still equipped one of them with a good horse, Ashina Helu, who is now living in the horse farm in the East Palace. As a Turk, he liked to herd and raise horses, and although he was always watched, he felt that he had gained some freedom and was satisfied with his treatment.

Especially after learning that he would be able to return to the Turks in a few years, he completely gave up the idea of escaping.

Now that Ye Hu is in the Turks, it is indeed not a good time to go back, he just hopes that the forces that his father has dismissed will not all die out.

Li Chengqian had just arrived at Chongming Gate when he was stopped by a half-old girl.

It is Li Liqing, the princess of Changle.

Afraid that the war horse would bump into this girl, Li Chengqian, who was far away, stopped the horse, jumped down, and led the horse over.

"Stinky girl, who told you could stand in front of the main entrance? What should I do if I am hit by a horse? ”

Handing over the war horse to the guards who came over, Li Chengqian reached out and knocked on Li Liqian's head.

Li Lizhi immediately pursed her lips and said, "Brother Huang, you stink, you have such a beautiful hairpin, why don't you give it to Su Yuan and give it to me?" He also said that he would not give it until I grew up, I think you want to give all the good ones to your daughter-in-law in advance! ”

Li Chengqian immediately covered her mouth: "How do you know that my fiancée is Su Yuan's?" Have you met? ”

Breaking away from Li Chengqian's hand, Li Lizhi muttered: "The queen mother took me there, and after we met, the queen mother let us chat, and she chatted with the mother of the Su family." I see that the hairpin on her head is very good-looking, and it is still shiny when the sun shines, which is better than the glass! I don't care, I want one too! ”

didn't know how to tell her about the reel, Li Chengqian could only say helplessly: "Aren't you still young, don't worry, the same hairpin brother is still here, and there is always your share." But you can't use a hairpin yet, it's okay for my brother to give you a bottle of perfume, as long as you spray it on your body, it will become fragrant. Xiangxiang's little beauty, anyone who sees it will like it. ”

"Really?"

Hearing that there was something else, Li Lizhi immediately stopped pouting. She also knew that she was not old enough to wear a hairpin, and she was only here for a benefit today.

"Of course it's true, but good things can't be given to you in vain, the next time the queen mother takes you to Su's house, you have to help my brother send something over..."

After the obscene uncle made Li Li happy, Li Chengqian instructed the guards to go to the auction house to get a few perfumes and diamond hairpins.

As early as when he was worried about the bottomless pit of the college's construction, he came up with a brilliant way to make money.

There is no market for diamonds in Datang, and women prefer gemstones.

Although Hu Zi likes it, this thing is not worth much in the eyes of Hu Shang. Because of this, the caravans in the Western Regions have been collecting diamonds with all their might for a while.

If the color is poor, it will be sent to the glass workshop to be used as a glass knife, and if there is a natural mirror, it will be made into jewelry.

As for perfumes, when I was studying aromatic hydrocarbons in high school chemistry, my chemistry teacher mentioned it. Perfume is simple to make, and it is simpler to use than incense, so there is no reason why it will not be liked by women in Chang'an. Judging from the fact that a piece of ambergris was auctioned off at a very high price at the last auction, it seems that the money of Datang women is also very profitable!

However, good products always need a suitable marketing plan, although these two things have been produced, Li Chengqian is still ready to hold back again, at least, he has to pull the queen to help promote it.

After giving Changle a bottle of perfume and instructing her to bring a bottle to Su Yuan next time, Li Chengqian took the remaining perfume and hairpin to the Liangyi Hall to ask to see the eldest grandson.

There is a reason why I chose today, I specially asked Zhang Yun about it, usually at the end of the month, the emperor will not stay in the Liangyi Palace, and will be driven by the queen to the Ganlu Palace, or where the other concubines will go.

When a woman has menstruation, husband and wife cannot have sex together, which is a sick rule in many large families. Although the emperor didn't care, the eldest grandson strongly urged him to comply.

The Liangyi Palace, which is not the palace of the king of Hades without the emperor's presence, walked into the palace gate, and after the peace was finished, Li Chengqian naturally sat down next to the eldest grandson and said: "I heard Changle say that you went to the Su family again, then you must know that the child is doing something wrong, and the son is acting recklessly, please punish the queen mother." ”

The eldest grandson slapped him angrily: "You still know how to ask for sin, although your father doesn't think so, it's not good to be known by others." But you have a lot more heart than your father, and the beautiful hairpin on Su's head was given to her by you. ”

"Queen Mother Mingjian, that one was indeed given to her by the child. I know you'll like it too, so I've prepared a few for you. ”

After speaking, Li Chengqian beckoned, and Zhang Yun sent the gift box over.

The box is made of sandalwood, and the inside is lined with black silk, which can better set off the brilliance of the diamond.

casually picked up a gift box, took out the diamond gold hairpin inside and looked at it, the eldest grandson smiled: "Fortunately, your child still knows the queen mother, but looking at your gift box, it must be bad again." I have never heard of this kind of gem, with your temperament, it is strange that it is not sold for a sky-high price! ”

Li Chengqian didn't expect his plan to be seen by his eldest grandson so quickly, so he could only confess and be lenient.

He took the perfume from another box, opened the bottle, and sprinkled a little bit on his palm before asking the eldest grandson to smell it.

After smelling it, closing his eyes and pondering for a long time, the eldest grandson was surprised: "This is the smell of osmanthus, what is this thing of yours?" ”

"Perfume can replace incense, saving time and effort, and not only osmanthus fragrance, as long as it is a smelly flower, it can generally be made into perfume. Mother, do you think this thing can be sold for a good price? ”

"It's good, but don't set the price too high. Cheng Qian, although you are in charge of the Wang family's incident, what you have done is still too despicable. Be careful during this time and don't leave a message for outsiders. Although your crown prince's position is as stable as Mount Tai, and your father and I will not change Qingque or other princes, your reputation is still very important. ”

Li Chengqian smiled: "Don't worry, the queen mother, the child naturally knows how to do it." ”

It's enough to do something drastic once. Just like a tiger in the mountains and forests, when necessary, it is okay to roar and tell the ill-intentioned kinders to get away, and if you are idle and have nothing to do, won't you scare the prey away?

It's the same when the crown prince is the same, he is usually kinder, smiles at everyone, maintains the appearance of "loyalty, kindness and benevolence", and when someone moves his mind, he will give a thunderous blow. In this way, it is better than blindly cowardly and blindly tough, I don't know how much.

For the child's filial piety, the eldest grandson naturally accepted it with peace of mind, and even gave a bottle of perfume to Yuzhang casually. It is rare to be a stepmother who can be the queen of her own mother.

Seeing Yu Zhang leave with a smile, Li Chengqian asked: "Queen Mother, did my father decide to marry Yu Zhang to the eldest grandson?" ”

The eldest grandson nodded: "It can only be Yuzhang, your father has found several Taoist priests, and they all say that Changle and Changsun Chong do not agree, and it can only be Yuzhang." However, Yuzhang is younger than Changle, so he has to wait for Changle's marriage to be finalized before he can reach her. ”

Li Chengqian nodded, perhaps, Changle could only exchange with Yu Zhang and marry into Tang Jian's family.

Although Tang Jian's status is very different from the identity of Changle's eldest daughter, it can only be like this for now. He had every reason to believe that the emperor's father had now allocated all his daughters, including those who were still nursing.

Now those who occupy high positions have become his old team, and the vote who supported him desperately during the Qin Wangfu period, he definitely needs to get closer. Marriage is the most useless and the best means.

"What do you think? So fascinating. ”

Hearing the voice of the eldest grandson, Li Chengqian realized that this was not the East Palace.

glanced at Li Zhi, who was gnawing on the dried fruit, and said: "I'm thinking about the pheasant slave, although Jinyang is the foundation of our Li family, but it is not Tongzhou Dayi, and the pheasant slave was named the king of Jin, is it too much different from Qingque?" ”

The eldest grandson nodded at Li Chengqian's head and said, "You are thinking wrong, do you think that Qingque has a lot of fiefdoms and is profitable, so it is better than the pheasant slave?" Not necessarily, Jinyang is the foundation of the Li family, the title of King of Jin, but it bears the fortune of the country. Do you think that when the pheasant slave was crowned king, there were no courtiers who objected? ”

Hearing what the eldest grandson said, Li Chengqian reacted, it seems that King Jin is really powerful?

Seeing that Li Zhi still had a whole bag of dried fruits in his left hand, Li Chengqian pretended to reach out to grab it, but who knew that Li Zhi reacted quickly, and ran away with the dried fruits.

"Bastard boy, be careful that my brother won't give you good things in the future!"

After laughing and scolding, he got up and said goodbye.

"Why are you in a hurry to leave, although there are two women in your East Palace, the queen mother doesn't seem to have moved them when she sees you!"

Although it is a bit unrestrained to talk about the relationship between men and women, the eldest grandson is the queen, so he is in charge of this.

Scratching his head, Li Chengqian said helplessly: "Mr. Sun said that it is best for men and women to have sex after the age of eighteen, otherwise it will be harmful to the body." In fact, it's a matter of three or five years, and you still have to wait if you want to hold your grandson. ”

In a word, the eldest grandson thinks about it, if there is no Sun Simiao, the prince is probably married at this time, as for the current situation, the princess will still be hidden?

However, thinking of the hardships of his own child, the eldest grandson gritted his teeth and said: "Although Xiuxiu is a palace maid, she is knowledgeable and courteous, and she is also very attentive to learning various etiquette. Now that you are not married, you have three women who are determined, and the queen mother still feels a little little, otherwise, how many will you choose? ”

Hearing this, Li Chengqian's hairs immediately rose. Although three wives and six concubines are the wishes of every man, but if there are more women, the relationship is not valuable. Although he is in the position of the crown prince, he has decided to accept the marriage arrangement painfully and happily. However, no matter how much it is, it will kill you!

Waving his hand again and again, Li Chengqian said: "It's better to say goodbye, Erchen can only watch now, isn't it torture for Erchen to choose so many concubines for Erchen, let's wait for Erchen to get married." ”

After saying that, he ran away as if fleeing.

Seeing Li Chengqian's reaction like Li Tai, the eldest grandson behind laughed.

As a parent, after all, you want to tease your child with this.
