Li Su was almost sure that the poems recited by Shangguan Tingzhi must have been copied by Shangguan Yi in the letters held by the person who received them, and it was by no means that his own poems had been widely circulated to such a point.

You must know that Shangguanyi's family is very poor.

When he went to Chang'an to catch the exam, he didn't even have enough money for accommodation and food.

Li Su's poems, first, may not be so fast.

Second, even if it is circulated, it is also circulated among Shilin, how can it reach the ears of Shangguan Tingzhi, a little child?

However, Li Su was not disgusted by Shangguanyi's hand.

Anyway, Shangguanyi's personality is still credible, and besides, Li Yu is actually confident enough to be able to control him.

……

On this day, a very inconspicuous incident occurred in the Tang Dynasty.

Tang Taizong Li Shimin recalled Du Yan, who was exiled due to being implicated by the hidden prince Li Jiancheng, from Wangzhou, and then Du Yan recommended a talent to Li Shimin, Yuan Tiangang.

claimed that Yuan Tiangang was a prodigy in Shudi.

Du Yan's words aroused Li Shimin's curiosity, so Li Shimin summoned Yuan Tiangang to Chang'an for an audience.

When Li Chunfeng, who was located in the Taishi Bureau, learned about this, he was immediately excited.

It turned out that Li Chunfeng had been admiring Yuan Tiangang for a long time, and he had always been stingy when he saw him.

And if Yuan Tiangang can enter Chang'an this time, Li Chunfeng can just ask him for advice.

Li Chunfeng had a great doubt in his heart, suffering from the fact that there was no one to talk about, and no one to consult.

It's really good that Yuan Tiangang can come.

It turns out that Li Chunfeng's divination ability is also rare in the world, and when he has nothing to do, he has also calculated the evolution of future generations after the Tang Dynasty.

But just this year, he was surprised to find that all the results of his original divination had been overturned.

Li Chunfeng does not believe in evil, and he has calculated it several times in a row.

For example, in his original calculation, after Li Shimin, Datang will inevitably produce an empress surnamed Wu.

But this year, this hexagram is completely invisible.

Other hexagrams have also become confusing and obscure.

Therefore, Li Chunfeng felt that it seemed that someone had performed the technique of changing his life against the sky, and he forcibly pushed the luck of the entire Tang Dynasty into the unknown.

But who exactly has such magical powers, Li Chunfeng is secretive, and he can't guess at all.

It's really good that Yuan Tiangang can come this time, and you can just ask him for advice.

……

In King Liang's mansion, Cheng Chuliang and a few other friends suddenly discovered the football game in the army, which was love at first sight.

A few guys immediately left the field to form a team of their own, and of course, the result was that they were bullied by those soldiers very badly.

Then Cheng Chuliang was not convinced, and asked Li Su to ask for skills.

Li Su smiled slightly, you are not as old as those soldiers, your strength is not as strong as theirs, and your skills are not as good as others, what can you do to win the game?

However, Li Su had no choice but to give them an idea: "First of all, you must form a fixed team, right?" Only by working together can we win. ”

"Secondly, you have to form a formation. Let's say you need to find a full-time goalkeeper. Find four more defenders and focus on defending. Four center forwards, forming the first line of defense in the middle line, can connect the upper and lower lines. There are also two strikers who are waiting in the opposing half, and as soon as they receive the ball, they can shoot immediately! ”

In fact, Li Su is just an amateur and doesn't understand advanced tactics at all.

It's just a little bit of a routine that is basically known to everyone in later generations.

However, this is definitely an epoch-making change for a football game that is just emerging and does not even have a goalkeeper.

After listening to Li Su's skills, Cheng Chuliang nodded excitedly.

Then he shouted directly at his friends to leave and prepare to form a team.

Li Su is too lazy to take care of this goods, and now Li Su is preparing for the construction of the fiefdom in the future.

Now, Li Su has a new understanding of his pit system.

With this system, almost all high-tech products can be redeemed.

But it is simply impossible to rely on the system mall to directly make Datang a thousand years ahead of the progress at once.

For example, as long as the loser has enough value, he can buy a car, or even a train and a plane in the mall.

But Li Su estimated that even if he defeated the entire Datang, he would be able to buy a few hundred cars at most.

And, after buying these cars, nothing else can be done.

Can thousands of cars directly push Datang forward with thousands of years of technology? The answer is definitely no.

Therefore, if you want to develop Datang, you must develop science and technology in Datang.

Mall, at best, is an auxiliary.

In order to develop science and technology, it is necessary to find suitable scientific and technological talents, and then set up new schools to disseminate modern science in large quantities.

And now, Li Su is preparing future science textbooks.

In later generations, textbooks for elementary school and university students and even graduate and doctoral students can be purchased.

But you can't just use it.

A lot of things have to be changed accordingly.

Moreover, Li Su must also take into account Datang's receptivity.

The courses that Li Su is going to do now include seven courses, including physics, chemistry, astronomy, geography, biology, mathematics, and medicine.

At present, the mathematics teacher has been found, it is Mr. Wang Xiaotong of arithmetic, and the medical teacher also has it, Sun Simiao, the king of medicine.

However, teachers of physics, chemistry, astronomy, geography, and biology have not been found.

Li Su was also in a hurry, so he could only sort out these textbooks first.

And, for the construction of the fiefdom in the future, Li Su began to plan.

Since he was born as a traverser, if he can't make a feat that shocks future generations, wouldn't he lose the face of the traversal? What is the difference between salted fish?

……

At this time, in the land of Qinghe, as well as the area near Qinghe, there were suddenly cheap books for sale.

Exquisite paper, exquisite engraving, and an annotated version of the exam book, the price of one book is only 500 wen!

This price directly stunned those poor students.

Is it really that cheap?

Not to mention the annotated version of the exam book, even if it is an ordinary version, which one does not cost two or three times?

And the annotated version is not sold at all, and they may not even be able to borrow it.

So, after those poor students heard this price, they were almost crazy with joy.

I hurriedly sold my property or borrowed money to buy books.

If they had to put it on hold, even if they sold their property, they wouldn't be able to afford a copy.

For a while, Qinghe and the surrounding area, this annotated version of the exam book was selling like crazy.

Not only that, but booksellers from other regions are rushing to wholesale when they hear the news.
