Li You said it up, and for a while he pouted.

When he noticed that everyone was staring at him, he quickly shut up and wanted to say something else to cover up the past.

He said: "Objects change lives, such as cement ......"

"Wait a minute." Li Shimin stopped him.

Li You pretended to be stupid and asked, "Father, what's the matter?" ”

Li Shimin asked: "What gunpowder did you just say, and what is the matter with hot weapons?" ”

Li You was very entangled, once such a thing as gunpowder came out, it would not only be able to change the form of war, but also have a greater impact on the social life of the entire human race.

As a foodie, in the Tang Dynasty, in the era of cold weapons like the Tang Dynasty, he lived a stable life as a top nobleman, and once the monster of gunpowder came out, it would change the structure of the world, including the current social hierarchy.

When a child picks up a gun and can easily kill a martial arts master who has been practicing hard for decades, people's ranks and values will change dramatically. He can't live a good life as a foodie.

The most important thing is that Li You has always thought that he can't control this kind of thing, so he didn't release this monster.

Li You thought for a while and said, "Father, the son is looking at it from the parchment scroll, and it says that when the Gewu develops to a certain extent, it will reach that point. However, there is no specific method described above, and this needs to be studied slowly in the future. ”

Li Jing said: "Your Majesty, the minister thinks that Gewu is indeed very useful. Over the years, His Royal Highness has invented many novel things through Gewu, which has brought significant changes to the Tang Dynasty.

For example, the method of salt production, as well as sugar, perfume, soap, alcohol, cement and high-yield grain, etc., have brought great benefits to Datang.

A novelty like a radio station was unheard of before, and I couldn't even think of it. Who would have thought that what happened thousands of miles away could be known in an instant through this device.

The minister suggested that the imperial court should vigorously develop Gewu, in a sense, Gewu is more important than expanding the territory. ”

Li Ji and Li Daozong also agreed.

Li Shimin nodded and said: "I have always had this idea, when Li You was only 16 years old, he said that if he went to the research institute, he would be able to double the financial income of the imperial court within three years, and the results have been realized." Over the years, Datang's wealth has increased more than tenfold.

As the saying goes, the country is rich and the people are strong. Only when the country is rich can the people be strong. Only when the country is rich can the imperial court have the money to build roads and water conservancy facilities, to recruit soldiers to improve equipment, etc. ”

At this point, he was silent for a moment, as if considering something important. Everyone saw him in a daze, and no one dared to disturb his train of thought, and they all waited for him silently

At this time, Li Shimin was making a decision in his heart that he wanted to do, but was a little hesitant.

Over the years, Li You has made great contributions to the imperial court. However, compared with other aspects of increasing the wealth of the imperial court, these achievements seem to be far inferior to the latter.

Li Shimin really wants to transfer Li You back, improve the structure of the research institute, and take full responsibility for the problems of people's livelihood.

Moreover, when encountering all kinds of major matters in the imperial court, Li You can put forward valuable suggestions.

To sum up, Li You's stay in Chang'an was more useful to the imperial court than his stay in the northwest.

However, this still involves a contradiction and dispute between princes. If Li You stays in Chang'an, what will Li Ke and the others think? Thinking of this, he suddenly thought of Li Tai again, from a personal point of view, Li Tai is even more loved by Li Shimin.

He really wanted to get Li Tai back now.

Because this matter is too complicated, Li Shimin hasn't thought about it for a while. So he said to Li You: "You go on." ”

Then the crowd continued to discuss the question of Gewu.

Ever since the telegraph was issued, Li Chengqian would make routine reports to Li Shimin every day. Li Shimin cared about the health of the eldest grandson Empress and often greeted her in telegrams. The calls he received were all healthy and safe, so he was also relieved.

Suddenly, one day, Li Tai sent someone to come, and he wrote a letter to Li Shimin saying that the first day was coming, and it was the queen mother who asked him to return to Chang'an.

If it was in normal times, Empress Changsun asked Li Tai to return to Chang'an, Li Shimin would definitely feel that there was a problem. At this time, it happened to be the first day, and a mother asked her son to come back for the New Year, which was nothing unusual.

So Li Shimin asked the visitor to go back and tell Li Tai that he would stay in Chang'an temporarily after he came back this time, and wait until he went back to meet him after fighting Goguryeo.

Li Tai was very clever and did not mention the physical condition of Empress Changsun, and he finally achieved his goal of staying in Chang'an.

Recently, Zhang Guigui has been like a Chinese New Year every day, and the supplies on the front line are relatively tight, but he has a way to get delicious and fun things from Li You to take care of Princess Suzy and win her favor.

Usually, he also went to play with Suzy, taught her to fight the landlord, and learned Korean with her.

On this day, Li You asked: "Precious, it's almost the New Year, send a telegram to the family, and report safety to your younger brothers and sisters." ”

Zhang Guigui has been only pursuing his love for Xiuzhi these days, and has temporarily forgotten his love for his wives and concubines at home. Hearing Li You say this, he said a little embarrassed: "Okay, I'll go over and send a telegram to my family." ”

Just as the first day was approaching, Li Chengqian made a special trip to send a lot of New Year's goods to the front line. Li Shimin was very happy and called back to praise his actions.

At this time, Li You proposed the measure that he had already implemented in the northwest region, and every soldier wrote a letter to his home before the first day to report his safety. Li Shimin thought that this method was very good, so he organized various departments to let those who were literate write letters to ordinary soldiers to report their safety.

At the same time, he also asked the political department to send good news to their families by the Eastern Expeditionary Army for those who had already been awarded meritorious service. This move caused a great sensation among the government and the opposition. It has enhanced the interaction between the military and the people, strengthened the relationship between the military and the people, and raised the morale of the officers and men.

In a blink of an eye, it was the first day, and Li You and Li Lizhi accompanied Li Shimin on the front line for the New Year.

With Li Shimin's approval, Li Ke, the king of Lingnan, also distributed a radio station.

On this day, Li Ke sent a good news to Li Shimin, the Southern Expeditionary Army broke the elephant army of Linyi State, captured the king of Linyi, occupied the capital of Linyi State, and Linyi State has been incorporated into the Tang Dynasty.

After the news was announced, the morale of the Eastern Expeditionary Army was greatly boosted.
