The crown prince and princess study the plough, which is not a serious business.

In the ordinary landlord's house, the education of the children is the top priority, not to mention the emperor's house.

Those who can't be touched are resolutely not allowed to touch it, and obviously the plough stick or something belongs to one of the flags that can't be touched, and if this is known by the minister, I don't know how many people will play impeachment.

It's not enough to impeach, the main thing is to study the plough stick to damage your reputation, have you heard that the prince and princess have studied this thing?

It has never appeared in any dynasty.

This is simply setting a precedent.

Especially for Li Shimin, because of the change in Xuanwumen, this emperor was even more infamous early, so he paid more attention to fame.

He is now beginning to make up for his brain, and later generations have commented in the history books that he is not strict with his godson.

So Li Shimin, who got the news, had to run over quickly.

"Father~~!"

"The son of the emperor to meet his father!"

"Erchen has seen his father!"

Li Shimin arrived, and Sanxiao, who was frowning around two ploughsticks, hurriedly got up to salute.

"Father, Lizhi is about to go to find his father, Lizhi has a question that he doesn't understand and wants to ask his father. After saying hello, Li Lizhen trotted all the way to Li Shimin's side, stretched out her hand to hold one of Li Shimin's hands and began to shake it.

With cute and soft words, Li Shimin couldn't resist it.

"Father, Qingque also has a problem. ”

"Father, Gao Ming has a question and wants to ask. ”

Li Liqian's voice fell, and Li Chengqian and Li Tai also spoke one after another.

Naturally, their so-called questions are the same as Li Lizhen's, they all want to know the difference between Quyuan plough and Zhiyuan plow.

As for why these two people are interested in this kind of thing, shouldn't this be Li Liqian's homework.

Because Li Lizhi promised the two of them that as long as they could help her complete this homework, then the things she brought back from Liu Tianyu could be selected by the two.

It can be seen that Li Lizhi is not a cute and coquettish girl, she is actually a little clever ghost.

Liu Tianyu's big names Li Chengqian and Li Tai have long been like thunder, especially the stun gun in Li Lizhen's hand.

To be honest, the two of them have been angry with Li Li's stun gun for a long time.

It's just that I heard that thing was specially given by the immortal family for Li Li's self-defense, and even their old son Li Shimin didn't dare to fight the idea of that thing, so naturally they didn't dare to covet that thing.

But Li Lizhen doesn't just have a stun gun in her hands.

Let's not talk about other delicious foods, Li Chengqian and Li Tai tasted it once, and it is still unforgettable.

Nowadays, in addition to the place of the immortal Liu Tianyu, the only kind of delicious food is available to Li Lizhen.

On the side of the immortals, they don't dare to be delusional, so only their own sister is left.

Therefore, the two of them are quite concerned about Li Liqian's homework.

In the eyes of the two of them, as long as they help Li Lizhen complete their homework, then it doesn't matter who helps Li Lizhen solve it in the end, they also contribute, so Li Lizhen should give them some remuneration.

So now that Li Lizhi spoke, the two of them hurriedly helped.

"Oh, let's talk about it, what's wrong with Lizhi?" Listening to Li Li's delicate voice, Li Shimin couldn't help but have a smile on his face, he seemed to have forgotten what he was doing here, and bent down to look at Xiaoli and asked.

"Father, what is the difference between this plough and the previous plough. Li Lizhi pulled Li Shimin to the new plough and said loudly, and at this time, the emperor finally remembered the purpose of this trip.

Li Shimin's face couldn't help but stiffen slightly, do I also want to study the plow, but when he saw three pairs of expectant eyes, he just swallowed what he wanted to say.

Never mind!

After secretly saying something in his heart, he began to observe this plow, which seemed to be different from the plough he was used to.

"Father, the national teacher assigned a homework to Lizhi, that is, to find out what is the difference between this new plough and the previous plough, Lizhi came to ask Erchen and the fourth brother, but the sons, and the fourth brother did not know about farming, so they could not help Liqin, and asked the father to solve the doubts for the sons. Li Chengqian saw Li Shimin's face on the side, because Li Lizhi changed when he talked about the ploughstick, and immediately reacted that his Lao Tzu should be related to his brother and sister's research on the plough stick, and quickly explained to Li Shimin at the moment, after all, Li Chengqian actually knew that it was very inappropriate to study the plowstick as them.

"National Teacher~~!" Listening to Li Chengqian's explanation, Li Shimin had a score in his heart.

He believed that Liu Tianyu, an immortal, would not be untargeted, and it was impossible for Li Lizhi to study the plough stick for no reason.

There must be some meaning in this, Li Shimin couldn't help but pay three points to his heart at the moment, and he was also a lot more careful when he watched the plowstick. 、

And then the eggs.

Li Shimin is indeed stronger than Li Liqian, Li Chengqian, and Li Tai in terms of farming, but it is definitely not too strong, and the strength is limited, at most it is from the south wall to the north wall.

Therefore, after squatting on the ground and watching for about a quarter of an hour, Li Shimin could also see the difference between the two kinds of ploughsticks.

Seeing that his Lao Tzu was squatting down to study, Li Lizhen waited patiently until his Lao Tzu raised his head, Li Lizhi looked at him hopefully and asked, "Father, do you see something?"

In Li Lizhen's opinion, in addition to his own father, his father is the most powerful, almost omnipotent, and he will definitely be able to tie himself up.

However·····

Li Shimin raised his head very much, because he couldn't stand it after squatting and bowing his head for a long time, so he raised his head to soothe it, not because he had found the difference between the two kinds of ploughsticks.

But in the face of his daughter's inquiry, Li Shimin couldn't say that I didn't see anything, isn't this hurting my prestige.

Fortunately, Li Shimin is also anxious, thinking that the current problem is two types of ploughsticks, so what is the difference between the two types of ploughsticks, just try it.

At the moment, Li Shimin's words seemed to have a trace of certainty: "Since it is a plough, then go to farming and see, don't you know the difference?!"

The eyes of the three children present lit up when they heard this, because they were all in the palace, and there was no chance to go out at all, and as for where the palace had land for them to cultivate.

It's just that what they didn't notice was that their father's eyes seemed to be a little drifting, and in fact, Li Shimin had no confidence in his words.

He just felt that Liu Tianyu would not be untargeted, and there must be some point in assigning this kind of homework, but Li Shimin couldn't find the meaning of it.

Just now he seemed to be conclusive, but as he said just now, Li Shimin is anxious.

He was just an excuse to avoid embarrassment in front of his own children.

"Father, hurry up, let's go and give it a try. Little Lori Li Lizhi saw the hope of completing her homework, and her mouth was crispy at the moment.

"Okay, I'll let someone arrange it. "It is true that there are no ploughing cattle and no land in the palace for Li Lizhi to experiment with ploughsticks, but there is a place outside the palace, and although Li Shimin is also a little bottomless in his heart about 'try it to know the difference between the two ploughsticks', but Li Shimin's intuition told him that Liu Tianyu must have other meanings in arranging this role for Li Lizhen, and Li Shimin also has a plan to get a glimpse of this meaning, so he immediately arranged someone to prepare.

The order is given, and after a short time someone returns, everything is ready.

So, Li Shimin set off with three small radish heads.

Coming to the experimental field where everything was ready, Li Shimin ordered.

"Let people start plowing the land, I'm going to see how the two kinds of plows are different. ”

As Li Shimin's words fell, on a barren field not far away, four ploughing oxen began to move slowly in pairs, one using a curved plow and one using a straight plow.

And just from the beginning, those present saw some clues.

"The new plough seems to plough the ground faster. ”

Li Lizhi immediately showed a bright smile on her face after hearing this, she felt that this should be the answer her father wanted.

As for Li Chengqian and Li Tai, they also nodded, their faces were very happy, obviously they felt that Li Liqian had completed his homework, so they had a good fortune to reap.

Li Shimin on the side originally observed carefully, but gradually, his eyes began to focus, which was different from the observation of children.

Li Shimin could feel that the two ploughing oxen pulling the new plough seemed to have a relaxed and even leisurely look.

"Jun Xian, the new plough is reduced by a ploughing ox. After observing for a long time, Li Shimin said to his number one guard, with a hint of seriousness in his words.

"Yes, Your Majesty!" Li Junxian didn't ask why, and directly instructed, because he was born in the Li clan, so he didn't understand farming, but he did whatever His Majesty said.

That's right, Junxian, Li Junxian, is the Li Junxian who has a leg with Wu Zetian in some TV series.

Okay, it's a bit off-topic, Li Junxian or something will be talked about later, but now let's get back to the point.

It is said that Li Junxian made the new plough according to Li Shimin's order, that is, after Quyuan plough reduced one ploughing ox.

The new plough was not unable to work because of the lack of a cow, and the new plough could still plough the land, and at this moment, Li Shimin's eyes flashed with a fine light.

"If there is one less ploughing cow, how much manpower and material resources can Datang can reduce. ”

You must know that because of the scarcity of cultivated cattle, every spring ploughing in Datang is a big problem, and even some people have abandoned their fields because they can't get ploughing cattle.

And looking at the obvious appearance that a cow still has strength left, Li Shimin's eyes were bright and did not go out, and he couldn't help but continue to speak.

"Replace the new plow and replace it with someone to pull it up. ”

This time, Li Junxian also did not hesitate, and changed into a hundred horsemen to escort him.

Under Li Shimin's gaze, the guards slowly pulled the new plow, although the movement was a little slow, but it was only slower than the old plow.

Although it didn't take long for him to sweat profusely, the light in Li Shimin's eyes was getting brighter and brighter.

"Sure enough, I knew that the national teacher would not be untargeted!"

"God bless me, God bless Datang!"

"God bless me, God bless Datang!"

Li Shimin was excited, and kept muttering softly.

In the past, there were immortal seeds with extremely high yields, and now if this new plow, which can greatly save manpower and accumulate power, will spread all over the world, then how much food can be produced every year, there will not be so much famine in the world, and if there is no famine in the world, then how peaceful it should be.

"Speed sent someone to invite the eldest grandson Wuji, Du Ruhui, and Fang Xuanling to come here. After losing his mind for a long time, Li Shimin said loudly, if he was worried that the prince and princess would have a stigma for studying the ploughstick, then now it is completely unnecessary.

This is enough to benefit the future generations, and even enough to be famous for eternity, so that the world does not know how many people are grateful.

Now Li Shimin, who has just ascended the throne, urgently needs to prove himself and needs the recognition of the people of the world.

Now is the chance.

Of course, Li Shimin will not forget the initiator Liu Tianyu.

However, Li Shimin believes that since Liu Tianyu asked his daughter to take out this thing, the real meaning is to let himself popularize the new plow.

Therefore, Li Shimin's gratitude to Liu Tianyu is now three points stronger, and he has begun to think about how to thank the immortal who always surprises him.

Since he got out of the horns, Li Shimin no longer worries about whether the things he sent are worthy of the identity of an immortal.

Li Shimin's definition of himself now is very clear.

Just like the subordinates of later generations often brought some souvenirs to their bosses on business trips.

I don't ask how expensive the gift is, but I hope that this heart can be felt.

During this time, Li Shimin did this, and ran to Liu Tianyu every three or five times, and then pulled over with a car regardless of whether it was useful or not.

Just when Li Shimin was thinking about what he would give to Liu Tianyu, several important ministers of the court and the central government had already come in a hurry, but there was a trace of doubt on their faces, and they didn't know why Li Shimin summoned them, and why they were in the fields, and they couldn't figure it out along the way.

"Auxiliary, Keming, Xuan Ling, come and see what the difference is. After seeing the arrival of the three of them, Li Shimin retracted his thoughts, and said with a smile on his face, even the courtesy of the monarch and ministers was temporarily ignored by him, obviously he was very happy, which made the three of them a little confused, and they didn't know why Li Shimin was so happy.

However, when they saw the plough in the barren field and the excited prince on the side, the three of them had some strange expressions.

There is nothing to hide in the palace, and the princes and princesses have also heard about the ploughsticks, and they even know that there are already officials ready to impeach the prince and the princess on this matter.

And the most disturbing of the three is the eldest grandson Wuji, after all, the three princes and princesses are his nephews and nieces.

However, now Li Shimin seemed to be very happy, as if he didn't care at all about his son and daughter studying the plough stick, and the three of them couldn't help but pay attention to the plow stick that was plowing the field.

Speaking of farming, Fang Xuanling and Du Ruhui are obviously stronger than Li Shimin, and they are not strong from the south wall to the north wall, but they are really strong and proficient, after all, the household department has to calculate the number of cultivated cattle.

Therefore, they are still clear about the basic common sense of farming, such as the plough needs two oxen to pull.

So it only took a moment for them to realize that something was wrong.
