Datang Storyteller: Uncovering the Secret of Xuanwu Gate, Li Er was stunned

"Well, that's about the same."

Li Shimin nodded in satisfaction. It was already an extra favor for him to let Cui Ren listen to this here for free today.

He still wants to research it?
What if he doesn't exist?
Even if he hasn't researched it yet, Li Shimin knows it's a good thing just by hearing Qin Yu mention it.

What is Datang missing now?
A group of scholars.

The reason why the Tang Dynasty lacks scholars is entirely because there are no books in the court, and there is no way to let the children of poor families have books to read.

Even though Datang had started the imperial examination system, the selected talents still came from aristocratic families.

Although the children of the aristocratic family have good talents and studies, their disadvantages are also obvious.

On the one hand, they come from aristocratic families, and what they do is mainly based on the aristocratic family, and all they consider are the interests of the family. Compared with the family, the court and the monarch will be much less important.

On the other hand, they have a good living environment and have not experienced any hardships. When doing things, they can't think about things from the perspective of ordinary people.

To put it bluntly, I have never experienced the hardships of life, and I don't understand the sufferings of the people.

It is not an exaggeration to say that they do not work hard and do not distinguish between five grains.

This is also the reason why Li Shimin, who is diligent in government and loves the people, has not changed the plight of the people in Datang after several years.

Natural disasters are indeed one aspect, but man-made disasters are also included.

And most of this man-made disaster originated from the family.

Li Shimin is in the contradiction of relying on the aristocratic family and wanting to get rid of it quickly.

If it is said that books are the first thing that Datang lacked, then the second thing that is lacking is weapons.

In the past few years of his reign, Datang has never stopped fighting. Datang is the world that Li Shimin fought from horseback, so he naturally knows the importance of weapons.

If this gunpowder can be researched and used for war, then the strength of the Tang army will rise to a higher level.

Li Shimin felt extremely excited just thinking about it.

Not only Li Shimin was equally excited, but also Li Yuan, Li Chengqian, and Li Ke.

Men have blood in their bodies.

Especially as princes, they are naturally eager to make contributions.

Naturally, I also hope that the country will be strong.

Weapons and armies are the foundation of a country's prosperity.

"Brother-in-law, can you make all the things you said?"

Li Tai asked excitedly.

"Yes, brother-in-law, if we have these things, why are we afraid of Turks, Tuyuhun?"

Li Ke also looked excited.

Qin Yu smiled and said, "Since I can talk about it, someone has made it. If you know that there is nothing difficult in the world, it depends on your determination whether you can make it or not."

He didn't directly tell them that he could do it. Some things will be more precious and more cherished after they have been paid and then obtained.

When Li Chengqian heard this, he suddenly had a plan in his mind, and quickly stood up and said: "Father, my son is willing to be responsible for the research of gunpowder and printing."

Li Shimin looked at Li Chengqian, and seeing his eagerness for quick success, he was a little disappointed.

He, the prince, still doesn't know what he should do.

"Father, emperor and ministers are also willing."

Li Ke also stood up.

It is undeniable that whether it is printing or gunpowder, as long as the development is successful, it is a great contribution.

Not excited, how is it possible?

Li Shimin didn't speak, but looked at Qin Yu.

"What do you think?"

Qin Yu smiled, and kicked the ball back with a snap, "Your Majesty, it seems that it's not my turn to worry about this matter. Isn't it your business to appoint who is responsible for the research of gunpowder and movable type printing?"

Li Shimin choked.

"It's my business, but I want to hear your opinion. After all, we only know about these two things because of you. It is natural and reasonable for you to help me make this decision."

Qin Yu didn't refute, but nodded seriously, and said, "Since that's the case, I think it's better for His Majesty to be responsible for this matter, or let the Supreme Emperor be responsible, and the Crown Prince and the King of Shu will assist."

Li Shimin rejected Li Chengqian once, and wanted to refuse again, afraid of hurting his son's heart, so he let him be the bad guy.

How could Qin Yu let him get what he wanted?

Since you don't want to refuse, then both of you want it.

Anyway, if you just help from the side, you can neither get credit from the Lord nor offend others.

Although Qin Yu was not afraid of offending people at all, he still had to do something if he wanted to gain the approval of the King of Shu.

"That's it."

Li Shimin pondered for a moment, then finalized the matter.

Cui Ren was envious, and quickly stood up and said to Li Shimin: "Your Majesty, Cao Min is willing to lead the people to cooperate with Your Majesty."

Cui Ren is not stupid.

Gunpowder may not be much of a threat to them.

But movable type printing is definitely a bottom line for them.

Once developed, their business will suffer again, and it will shake the foundation.

Cui Ren also knew that he couldn't stop it. Instead of sitting still and waiting for death, it is better to take the initiative to develop it together with His Majesty. At that time, the aristocratic family will be able to participate in it, and the loss may be reduced.

Li Shimin frowned, but did not answer Cui Ren's words.

To be honest, in Li Shimin's mind, if they had movable type printing, they could completely suppress the aristocratic family. At that time, he would have no serious worries.

But now because of Qin Yu's relationship with the aristocratic family, Li Shimin hesitated.

And when he knew what kind of enemies Datang would face in the future, Li Shimin had suppressed his thoughts about the aristocratic family.

If you can join forces with the family, the effect will definitely be much better than turning against the family and increasing internal friction.

"Your Majesty, we have mature engraving and printing techniques in our hands and have sufficient experience. If we cooperate, the probability of success must be much higher."

Seeing Li Shimin hesitate, but did not refuse.

Cui Ren knew that he still had a chance, so he spoke up to fight for it again.

"Okay, then you and the emperor will be responsible for this matter together."

Cui Ren's words also gave Li Shimin a message that they want to cooperate.

That being the case, Li Shimin took advantage of the situation and agreed.

Qin Yu couldn't help but be a little surprised when Cui Ren said that they had mature engraving and printing techniques, "It seems that you are far more powerful than I imagined."

At first Qin Yu thought he was just an ordinary businessman, but later he found out that their business was quite big.

Now, Qin Yu found that they were far more powerful than he thought.

According to his understanding, Chaotang didn't know much about engraving and printing, but this Cui Ren actually had a mature technique.

This is obviously not simple.

Then contact Cui Ren's surname.

An answer immediately appeared.

"Are you from a family?"

"Yes, Mr. Qin, Cui Ren is the person in charge of the Qinghe Cui family in Chang'an City." Seeing that Qin Yu knew his identity, Cui Ren did not deny it, and honestly explained his details.

Qin Yu nodded, "No wonder that's the case. Then Lao Wang, Lao Li and Lao Zheng are also the heads of several other families?"

Cui Ren nodded awkwardly.

After all, it was a little embarrassing to be exposed for lying.

"I didn't hide it on purpose, please forgive me, sir."

Indeed, people like Cui Ren and Wang Gui did not hide anything. They thought that Qin Yu would know if they mentioned their names.

But who knew that Qin Yu didn't know them at all, and only regarded them as his fans.

And they themselves are not easy to expose, so they never talked about this matter.

"It's nothing, no need to apologize."

Qin Yu waved his hand and said indifferently.

He didn't hide his identity from the beginning, and used a fake name to fool him.

It was because he didn't know the other party's identity and mistook him for a simple fan.

I can't blame others at all.

If they were like Li Shimin, they would just use the title of second master to fool him.

Later, it was revealed that he was the king of Hejian County, Li Xiaogong.

This is blatant deception.

If Li Lizhi hadn't told him, Qin Yu didn't know how long it would be before he found out.

Li Shimin was also a little dumbfounded. He thought that his cooperation with the family was deliberately arranged by Qin Yu, but he didn't expect that Qin Yu didn't know the other party's identity at all.

This matter was arranged by accident.

But that's okay, with the research on printing, Chaotang and the family already have two cooperation projects.

This can be regarded as a win-win situation, and neither party will harm the interests of the other.

"Then this matter is settled like this, Qin Yu, please talk about these four great inventions carefully."

Li Shimin was completely interested.

He had a hunch that gunpowder and printing were so powerful, and the other Sinan, that is, the compass and papermaking should not be simple.

Qin Yu nodded, and began to popularize the four great inventions with Li Shimin and others.

After talking about gunpowder and printing in detail, Li Shimin and the others were taught how to use the compass.

"Speaking of this compass, sailing and survival in the wild must be mentioned. Needless to say, sailing is a vast sea, and the direction is difficult to distinguish. With this compass, you can determine the direction of sailing and make sure you will not deviate from the course."

"So the compass does matter."

After listening to Qin Yu, Li Tai said in agreement.

If Qin Yu didn't say it today, he really didn't know that sailing needed this thing.

"It's natural. Do you think sailing is just a matter of passion? Then you are too simple."

"Hey, brother-in-law, can you help me get out the compass? You said that if I lose it, my sister will not let you go."

Li Lizhi blushed, and reprimanded Li Tai, "Qing Que, what nonsense are you talking about, why did you lose it?"

"Hahaha... Sister, in order to ensure that I won't lose it, you have to help me persuade my brother-in-law to make sure he builds a compass for me."

"By the way, brother-in-law, you just mentioned the jungle, is it the same as sailing, you can use the compass to determine the direction?"

Li Tai's thinking is quite jumpy, one second he needs a compass, and the next second it becomes the use of a compass in the jungle.

Qin Yu nodded, "That's true. The main function of the compass is to help people identify the direction. Of course, there are also Feng Shui masters and fortune tellers who also use the compass as a compass to judge Feng Shui."

"In general, the compass is widely used." Qin Yu concluded.

As for the positioning system of later generations, he won't talk about it, anyway, they can't figure it out.
