As for the train, whether it is as magical as the King of Shu said, Wei Zheng still has doubts.

However, the King of Shu really hasn't bragged about it.

Regarding this problem, Wei Zheng decided not to dwell on it.

After all, such a controversy would be meaningless until the railroad was built and the train was built.

In that case, then simply leave this matter to the emperor to decide.

Immediately after, Wei Zheng asked the second question.

"Is the window of the teaching building of Yizhou University inlaid with crystal? How much do these crystals cost? Isn't this money too wasteful? ”

Hearing Wei Zheng's question, Li Su smiled and said, "Zheng Guogong, the windows of the teaching building are not inlaid with crystal, but glass. In fact, even the mirrors are made of glass. The cost of glass is much lower than that of crystal. ”

Of course, it is much lower, and as for how much lower, Li Su did not say it.

And Wei Zheng, I heard that it is actually glass, which is the raw material for making mirrors.

Actually, I didn't think it would be any lower than crystals.

However, he did not continue to dwell on this matter.

Instead, he directly asked his third question: "Your Highness, I wonder what is the use of the physics and chemistry subjects taught in your Yizhou University?" The imperial examination does not test these two subjects at all, and teaching these knowledge to schoolchildren is not a waste of time and misleading people's children? ”

It is also thanks to the fact that these two disciplines were opened by the King of Shu, and the King of Shu has created miracles many times.

Otherwise, Wei Zheng would inevitably reprimand these two disciplines as crooked and heretical.

However, since this was said by the King of Shu, even Wei Zheng did not dare to say so.

And Li Su couldn't help frowning slightly after hearing Wei Zheng's question.

Are physics and chemistry useful?

Nature is useful, and it is of great use.

However, in Datang, it is difficult to explain clearly.

Therefore, Li Su said to Wei Zheng lightly: "Zheng Guogong, the two disciplines of physics and chemistry are naturally useful. It will take five years at most, and it will be reflected. ”

In the face of Li Su's explanation, Wei Zheng frowned slightly, expressing his unacceptability.

However, he didn't say much.

As a messenger, the purpose of his visit is to find out the truth of the matter.

As for how to adjudicate, after going back, it is up to the emperor to decide.

And so far, Wei Zheng's task can be regarded as a successful completion.

Next, Li Su set up a banquet and prepared to wash the dust for Wei Zheng.

However, he was categorically rejected by Wei Zheng.

Wei Zheng directly bid farewell to the King of Shu, left the Mansion of the King of Shu, and lived in the post station.

On the second day, Wei Zheng returned the same way and prepared to return to Chang'an to resume his life.

However, before leaving, I bought a set of three-character scriptures, hundred family names and thousand-character texts.

Among these three books, except for the thousand-character text, it is an enlightenment book that has existed for a long time.

Like the three-character classic and the hundred family names, they were all written by the king of Shu.

Wei Zheng believes that the significance of these two books is no weaker than that of a thousand-character text.

In particular, the three-character classic is more suitable for enlightenment than the thousand-character text, and this kind of book is best promoted throughout the Tang Dynasty.

It's just that it's really not easy to achieve the point where everyone learns like Yizhou.

……

Not to mention Wei Zheng's sleeping in the open all the way, day and night.

said that on this day, Wu Meiniang came to find Li Su and proposed that she had an idea.

It turned out that the work of farming was carried out in an orderly manner by Wu Meiniang.

And now, it is even more rational to use manpower and decentralize power.

At present, the whole farming is on the right track.

Wu Meiniang only needs to listen to the reports of a few people under her command on a regular basis.

And Wu Meiniang, who made time to make time, came to Li Su this time because she had nothing to do, and she had a new idea.

After not seeing her for a while, Li Su found that Wu Meiniang was quietly changing.

It seems that because she has tens of thousands of mercenaries in her hands, Wu Meiniang, unconsciously, has some more high-ranking people's breath.

The temperament of a strong woman is gradually getting stronger.

Coupled with her beautiful appearance and charming temperament, it is even more charming.

And it seems that during this time, they haven't seen each other much, and Wu Meiniang and him have become a lot more estranged.

Thinking of this, Li Su smiled slightly, and directly reached out to grab Wu Meiniang's soft and hugged her into his arms.

Wu Meiniang's body stiffened slightly, and then she smiled like a flower, stretched out her jade arms, and hugged Li Su's waist.

"Mei Niang, it seems that I haven't talked to you for a long time? Did you miss me? ”

"Well, Mei Niang misses you! I wonder if Your Highness misses me? ”

Li Su smiled and said, "Why not?" This king thinks about you day and night, thinks about what you think, can't eat chopsticks, can't swallow bowls! ”

At the beginning of hearing Li Su's words, Wu Meiniang was still moved in her heart.

But soon it will be aftertaste, can't eat chopsticks and swallow the bowl?

You can't eat it in the first place, okay?

Thinking of this, Wu Meiniang was suddenly angry, and couldn't help but stretch out her little fist and beat Li Su's chest one by one.

"Mei Niang, I don't know if you came to me, what's the matter?"

Hearing Li Su's question, Wu Meiniang was still angry, and couldn't help but pout and said, "Isn't there anything wrong, can't you come to Your Highness?" ”

Li Su couldn't help laughing and said: "Now that your subordinates are in charge of tens of thousands of farmers, this king doesn't believe it, you are looking for this king for the wind and snow!" Say, what is the matter with you looking for this king? If you dare not tell the truth, then the king is going to spank the ass? ”

Let's say it, Li Su looked at Wu Meiniang's buttocks with bad intentions.

Wu Meiniang couldn't help but be warmed up by Li Su's pretty face, and hurriedly said, "Your Highness, it's like this." Now the railway has not been repaired. And if you want to repair the railway, I'm afraid it will take another year and a half. ”

"And if the railway is not repaired in a day, it will be difficult to transport materials from the outside world. This time was wasted. So, my thought is, during this time, can we do business with Nanzhao, Tubo and Tuyuhun? ”

After Wu Meiniang finished speaking, she couldn't help but feel apprehensive.

Because trading with foreigners is an extremely sensitive matter.

If one does not do well, there is a possibility of being suspected of collaborating with the enemy.

If the King of Shu was not Li Su, Wu Meiniang would not dare to make such a suggestion.

Even if the king of Shu is Li Su, Wu Meiniang is still worried in her heart.

And Li Su, hearing Wu Meiniang's suggestion, couldn't help but secretly praise it in her heart.

Because, this idea happens to be what Li Su wants to do next.

In the next step, Li Su not only had to do business with these foreigners.

Even the preparation and the technology of building roads were taught to them.

Unexpectedly, Wu Meiniang actually thought of going with him.

However, Li Su is still preparing to take the test for Wu Meiniang.
