Li Yan's appearance was completely different from what Li Yuan imagined.

In Li Yuan's original conjecture, the image of a peerless fierce general who can see tens of thousands of troops on the battlefield into nothing, rush and kill at will, and easily take the head of the enemy's general is not like Li Yan.

That kind of person should be more than nine feet tall, with arms thicker than the waist of ordinary people, and weigh at least two miles of gold.

How can it be like Li Yan, although his height is outstanding, but he is not beyond the level of a normal person, and his figure is not particularly strong, wearing a dark blue robe, he can't see any muscles at all.

"Are you Li Yan?"

Li Yuan confirmed curiously, he was unable to match Li Yan's image with his record.

"Emperor Qiyu, the minister is indeed Li Yan."

Although he didn't know what Li Yuan was thinking, Li Yan didn't want to snub the emperor.

To be honest, Li Yan was very skeptical that this Emperor Taishang was sent by Li Shimin to arrest him or something.

After all, Li Yan's merits are almost reaching the level of the earthquake lord, coupled with the disturbance made by the Tiangong Academy yesterday, even if the emperor makes a blatant move, it is not impossible for the emperor to make a bold move, and the announcement of the Tiangong Academy involves a lot of benefits.

Always speculating on Li Shimin's thoughts with the greatest malice, this is the criterion that Li Yan has always implemented.

Li Yuan continued to observe carefully, according to Li Shimin's previous account, Li Yan should be seriously injured and his time is short.

It stands to reason that a person who has been seriously injured in this way should have a bloodless face, even if he is not bedridden all day long.

However, this Li Yan did not look depressed in the slightest, and looked very healthy.

Li Yuan didn't ask about this, but pretended not to find out, and continued to communicate with Li Yan.

"I just heard that there are a lot of magical creations in this Heavenly Academy, and my rebellious son dislikes me for staying in the palace and drives me out of the palace, so I came to this Heavenly Academy to have a look and increase my knowledge."

Li Yuan's words always maintained extreme dissatisfaction with Li Shimin, and expressed it very bluntly.

"Since the Emperor Taishang is interested in the Tiangong Academy, the ministers should take the Emperor Taishang to watch it."

Li Yan didn't seem to hear that Li Yuan was harming Li Shimin, and his words were quite cautious.

In Li Yan's cognition, Li Yuan's words may be indicated by Li Shimin, which is likely to be Li Shimin's temptation of himself.

Once Li Shimin realizes that he has the slightest disrespect for the imperial power, then what awaits Li Yan next may be the encirclement and suppression of the forbidden army.

This is the idea of speculating on the emperor with the greatest malice at all times!

Li Yan never regarded Li Shimin as a human being, in Li Yan's eyes, the emperor was a black machine with no feelings!

"Okay."

A smile tugged at the corner of Li Yuan's mouth.

He can see that Li Yan is very smart, and this sense of avoiding suspicion is the same as Li Jing's under Li Shimin.

If Li Yan was not injured, and all of this was pretended, then Li Yan would definitely be a person who could live for a long time, and he would not be too bad.

Li Yuan was very curious about how Li Yan's slightly incomplete acting deceived Li Shimin.

No matter how Li Shimin says, he is also a scheming man who can ascend to the throne, and the city government is not ordinarily deep.

While thinking about Li Yan's situation, he followed Li Yan into the Tiangong Academy.

As soon as he walked into the Tiangong Academy, Li Yuan saw a bunch of inexplicable things.

The first thing to do was the paper drying on the row of shelves.

After living in the deep palace for a long time in the past two years, Li Yuan's early pastime was only reading and writing, traveling on the water, and planning how to turn the tables in adversity by the way, until the end of spring this year, Li Yuan got the news that his last confidant was transferred out of Chang'an by Li Shimin, and he began to give up on himself and had a love of making villains to decompress.

Therefore, Li Yuan was more sensitive to paper than mechanical creations, and he walked straight to the area where the paper was dried by a bamboo frame.

"Good paper, good paper!"

Li Yuan took a piece of paper that had just been dried and began to sigh.

This paper is slightly yellowish, but the thickness and toughness are far greater than the paper on which Li Yuan usually writes.

Holding this piece of paper, Li Yuan felt that even if he was careless with ink when writing, and it was stained with several large balls of ink, this piece of paper would not be so easy to break.

If it weren't for the yellowish color of this paper and the rough surface, then its quality would far exceed that of tribute paper and be worthy of the title of a generation of famous paper.

"Ah, this ......"

The papermaker who was checking the color of the paper and drying the new experimental paper by the way looked a little embarrassed, he really didn't know how to explain it to the Emperor.

"What? Could it be that the paper you usually make is not as good as this one? I remember that is not what you said in the notice of the Tiangong Academy, right? ”

Li Yuan still remembered the notice of the Tiangong Institute that Li Shimin told him, and the notice clearly said that the paper of the Tiangong Institute was comparable to tribute paper, and the price of the paper was ninety percent lower than that of ordinary paper.

Li Yuan originally thought that what the Tiangong Academy was talking about was the kind of paper in front of him, but now judging from the face of the papermaker, it was obviously not the same meaning, and Li Yuan's heart was a little disappointed in an instant.

"Emperor Qiqi, this paper ...... It...... This ......"

The papermaker was a little speechless, and he didn't even know how to explain it to Li Yuan.

"But it doesn't hurt to say it."

Li Yuan waved his hand and signaled the papermaker not to think too much, anyway, according to the price in the notice, even if the quality of the paper produced by the Tiangong Institute on weekdays is worse than this, it is completely acceptable, this is still a matter that is beneficial to Datang and the future.

"Emperor Qiyu, this paper is called straw paper, the quality is very poor, it is made of cheap materials such as grass ash and straw, and the use is...... Be...... Swab your feet. ”

The papermaker finished explaining, and then hurriedly lowered his head, not daring to look at Li Yuan's face.

"Wipe ...... Buttock? ”

Li Yuan was stunned on the spot, paper is an item for reading and writing, how can it be used to wipe his stomach?

This is simply an unforgivable waste!

Rao is Li Yuan's Cheng Mansion unconsciously showed a little anger on his face, I'm afraid that the Academy of Engineers is not inflated this day? Think that with a Qin Guogong behind his back, he can act so recklessly?

Even the children of the royal family can't do such outrageous things!

"Your Majesty the Emperor is calm down, you may have some misunderstandings."

"This paper is called straw paper, counterfeiting is extremely cheap, you can buy dozens of pieces for a penny in the future, this paper seems to be strong, but it is difficult to write, it is extremely easy to blur ink, so it can only be used to do some cheap things."

Li Yan didn't expect Li Yuan's reaction to be so big, so why did he explain.

He didn't want to let Li Yuan make a plan just because of the straw paper, and when Li Yuan said anything to Li Shimin casually, Li Shimin would have to go crazy.

Li Yan didn't want to be forced to rebel yet, although for him, rebellion was simply a matter of hand, and those Xuanjiawei and Jinwuwei in the palace were not enough for Li Yan to fight with one hand......

“……”

Li Yuan was silent on the spot, dozens of dollars a penny?

This price is definitely the lowest price among the cheap prices, even ordinary people can afford it, and it seems that it is okay to use it to do some cheap things.

"Emperor Qi, this is the paper used to write."

The papermaker was afraid that Li Yuan would not believe it, so he hurriedly brought white paper and handed it to Li Yuan.

Li Yuan subconsciously took it and took it in his hand a few times.

This paper is harder than Xuanzhi, almost a fight with those papers of slightly worse quality in later generations, but from the first sense of taking over, Li Yuan immediately thought that this paper was better than Xuanzhou tribute paper!

At least it's hard to break during normal use, but I don't know how it feels like to write.

"This paper, not bad."

Li Yuan didn't comment on anything easily, fortunately, his expression just collapsed a little, and he didn't scold directly, otherwise he would lose face.

In this way, Li Yuan quietly put down the paper and turned around and walked towards the position of the other machinery.

The first thing Li Yuan saw was the running paper machine, which was running with a steam engine.

Due to Li Yan's wealth, the fuel used in this steam engine is high-grade coal, although the cost performance is extremely low, but the smoke and dust produced is much less than that of firewood, and all of it is discharged through the flue, and there is basically no smell in the Tiangong Academy.

In the future, if a businessman purchases steam-powered machinery, he will inevitably use dry firewood or inferior coal, and the smoke and dust will not be small, so Li Yan must control the amount and limit the place of use when selling the corresponding machinery in the future, so as not to turn Datang into the fog capital of London during the Industrial Revolution.

Facts have proved that in the early stage of civilization development, the environment will inevitably be sacrificed to a certain extent, but as long as the technology of the Tiangong Academy under Li Yan develops fast enough, the damage can be minimized.

Maybe in a few years, Wang Xiaoxi will really go to research the atomic bomb......

All in all, Datang's industrial revolution will be carried out under Li Yan's control, and it will never get out of control.

Li Yuan looked at the machine that was moving by himself, and did not make any comments, but was very agitated in his heart.

For the sake of face, Li Yuan chose to see more and talk less.

Li Yuan's look at it is half an hour, the territory of the Tiangong Institute is not large, and there are only a few finished machines, and the machinery that will appear in the exhibition in a month is still a drawing, and Li Yuan can't understand the pictures.

But there is one thing that Li Yuan still understands.

That is, Datang has the existence of Tiangong Academy, which is bound to develop quite rapidly.

Although Li Yuan didn't know what economy was and what reputation was, as the former ruler of the Tang Dynasty, he also saw some clues.

Li Yuan suddenly became a little vigilant, he always felt that Li Yan was a little dangerous, although he still didn't understand where this danger came from.

A few seconds later, Li Yuan suddenly let out another long sigh.

What's the use of being vigilant, he is not the emperor, Li Shimin's throne has long been secured, and there is basically no hope for him to turn the tables against the wind.

His so-called fighting and fighting with Li Shimin means that he has the idea of disgusting Li Shimin, who let Li Shimin's throne come unjustly.

"That's it, that's it, anyway, the world is the rebel, I don't need to worry about it."

Li Yuan shook his head and left the Tiangong Academy in a hurry, he did have a lot of insight this time, but he also sensed the hidden dangers, but unfortunately he was no longer the emperor, even if he wanted to solve the hidden dangers, he didn't have the power.

And Li Yuan also felt that even if he was the emperor, there was nothing he could do to solve this hidden danger.

Datang needs the existence of the Tiangong Academy, and the emperor cannot abandon this opportunity to let Datang take off because of the slightest danger possibility.

After Li Yuan left, Tiangong Academy returned to calm.

"Li Yan, what did you say the Emperor was here for? Is this idle boring? ”

Wang Xiaoxi asked curiously, she couldn't understand Li Yuan's behavior at all, she was just a genius girl in science and engineering, and she was not an EQ explosion.

"Nine times out of ten, the emperor sent it."

Li Yan didn't know much either, but he knew how to speculate on Li Shimin with the greatest malice.

If there is something I don't understand, it's that the emperor is calculating behind his back!

As long as he does not die, the emperor will not find a reason to make trouble.

As long as the emperor doesn't make trouble, he Li Yan will be able to experience and make achievements in the Tang Dynasty peacefully.

If he turns his face with the emperor, he will have to rebel, if he rebels, it will be very troublesome, Li Yan is most afraid of trouble, he just wants to get out of the immortal cultivation module as soon as possible, and then live forever.

Li Yan continued to teach the craftsmen, and according to Li Yan's plan, a month later, after the Tiangong Academy released the first batch of light industry machinery, all the craftsmen of the Tiangong Academy would be sent to the Tiangong Academy to train the second batch of members for the Tiangong Academy.

When the number of people who meet the basic requirements of Tiangong Institute reaches three digits, Li Yan will step by step to carry out the basic education popularization plan, temporarily slow down the industrial development, and continue to consolidate the foundation for the future.

To sum up, Li Yan's plan has only two cores, that is, industrial development drives the economy, and economic development provides a guarantee for the popularization of basic education.

"Take your math test in three days, get ready."

Before leaving the Tiangong Academy and returning home, Li Yan gave an order to the ten seeded players.

Exams are always the most intuitive way to test your true level.

Before sending this group of people to Tiangong Academy to be teachers, Li Yan naturally had to ensure that their own level passed, otherwise when they went to Tiangong Academy to mislead people's children, there would be a big problem.

……

After the day's chores were over, Li Yan was stable here, but Li Yuan continued to be irritable.

Since Li Shimin did not arrange for Li Yuan to sit in a sedan chair, Li Yuan had to run all the way back to the imperial city from the Tiangong Courtyard in the northeast corner of Chang'an, even if he entered the palace from the nearest Suzaku Gate, it was the distance from the midpoint to the corner on the edge of the rectangle, not much shorter than the diagonal.

"Rebel! Rebel! ”

Li Yuan cursed Li Shimin as he walked, and even the anxiety about Tiangong Academy in his heart just now was forgotten.

"When you two go back to the palace, make it clear to me that rebel, if you don't prepare a sedan chair for me tomorrow, then don't blame me for not being merciful!"

"When the time comes, there will be hundreds of heirs in the Tang Dynasty, and I want to see how he Li Shimin divides the seal!"

Li Yuan directly picked out the matter.

His busy work all day to create villains is not a simple hobby, this is his premeditated and planned way to take revenge on Li Shimin.

He is purposefully expanding the royal population and making Li Shimin anxious.

In exchange for more than ten years of anxiety of Li Shimin with his own kidney, this wave is absolutely blood-earning.

After listening to Li Yuan's words, the two guards were silent on the spot, they were a little panicked, they could be regarded as hearing the royal secrets, they would not be killed by the emperor, right? Probably not, right?
