Zhang Baogui shouted at the top of his throat for a long time, but he didn't hear any response below. So they moved Kongming lanterns and arrived not far from the general's mansion, and threw pots downwards, which caused another fire.

The generals below knew that if this continued, the city would definitely not be able to be defended. They finally made up their minds to open the city and surrender.

They sent a loud voice to shout to the air, begging the Tang army on the monsters in the air to stop setting fires, and they decided to surrender.

Since Li You, Niu Jinda and others took off, they were uneasy and worried about what situation they had in the air.

Not long after, when they saw the fires soaring into the sky in the city, they knew that Zhang Mougui and others had succeeded.

Not long after, the Goguryeo people on the city wall shouted outside the city, saying that they had decided to surrender and asked the Tang army outside the city not to shoot arrows.

Then, the city gate opened, and several Goguryeo people walked out of the city without weapons. Soon, they were taken to Li You and others by Tang soldiers.

Subsequently, the Goguryeo army drove out of the city according to the orders of the Tang army and lowered the weapons according to the designated location.

The generals of Niu Jinda were both excited and extremely emotional - this city with such a dangerous terrain and extremely strong terrain was actually defeated.

None of the Tang army was injured or killed.

This incident once again attracted the attention of the senior officials of the Tang Dynasty, especially Li Shimin. He believed that the power of investigating things that Li You mentioned was too powerful.

Li Shimin sent a telegram to Li Chengqian, asking him to report on the situation of Chang'an Industry and Commerce and Research Institute.

After sending someone to investigate, Li Chengqian made a detailed report to Li Shimin.

When Li Shimin heard that the institute had been dead in name only and the main personnel began to move to Northwest Road, Wu Xu had already gone to Northwest Road before, and Yuchi Baoqi has resigned from his position as Minister of Industry and Commerce, and no new progress has been made in industry and commerce, he discovered that the focus of the industry and commerce and research institute chaired by Li You had turned to Northwest Road.

At this time, Gao Jingming also sent a telegram.

Gao Jingming can contact Li You directly, but at this time, Li You is by Li Shimin's side, so Gao Jingming is not convenient to go past Li Shimin and contact Li You directly.

So he sent a telegram to Li Shiminyu, asking to contact Li You to discuss the issue of establishing relevant exchange rates after trading with Persia, Tubo and other countries.

Only then did Li Shimin realize that these things were inseparable from Li You. He believed that Li You was really too important to the court.

Li Shimin finally made up his mind to keep Li You in Chang'an and take full control of the matter of investigating things.

After receiving the battle report from Niu Jinda and others, Li Shimin immediately ordered Li You to return to the commander-in-chief of the Eastern Expedition Army.

Afterwards, Li Shimin met Li You alone.

Li Shimin said: "Li You, report the situation in Northwest Road to me again."

Since Li You returned from Northwest Road, he has reported the basic situation there to Li Shimin. He heard Li Shimin ask this, he was a little puzzled and was thinking about how to focus on reporting.

Seeing Li You hesitate, Li Shimin said: "Don't talk about other aspects of Northwest Road. Just focus on the industry and commerce there and the development of things you mentioned."

Li You reported in detail one by one.

Li Shimin is generally clear about the situation in Kabul. It is relatively barren and industry and commerce are relatively backward. However, Li You has not been there for a long time, but there has been huge changes there. The economic development situation has surpassed most cities in the mainland of the Tang Dynasty.

Li Shimin said: "I heard that you moved the Chang'an research institutes to Northwest Road."

Li You said frankly: "Yes, father, most of the projects in the institute need to be presided over by the sons. Although there is a telegram now, it still feels very inconvenient. Because some things are not seen with your own eyes and on-site research, it is impossible to make accurate judgments.

Erchen is now in charge of the Northwest Road, and put the research institute around him, which is convenient for research on things. Every time Erchen invents an achievement, he will be sent to Chang'an immediately."

Li Shimin asked about this without blaming Li You, and Li You did not think about this. The mutual trust between father and son has always been very good.

Li Shimin nodded and said, "I believe this. Through your research on investigating things over the years, especially the current radio communications, and the achievements made by using Kongming lanterns these two times. I think the role of developing investigating things is far better than an army of 100,000 or even a million.

Although the matter of going there from the northwest is also very important, I think the study of things will make greater contributions to the court. It can play a more positive role in benefiting the people and increasing wealth.

Therefore, I decided to let you return to Chang'an to preside over the business world and the matter of investigating things."

This result was beyond Li You's expectations and also made him feel embarrassed.

Li You is now thinking about being the king of the Northwest, the emperor is far away, and living his own comfortable life. Li Shimin's decision disrupted his plan.

So he decided to fight for it.

He said: "Father, the Northwest Road is facing the four major powers of Persia, India, Tubo and Dashi. The situation is very complicated, and it is difficult for people who are not familiar with the situation to deal with these countries. Therefore, it is more convenient to stay there.

For industry, commerce and research on things, Erchen can also take into account both the matters of staying in the northwest. Especially now that there is radio communication, you can communicate with Chang'an at any time for major matters. Therefore, Erchen thinks that staying there can still play the role of Erchen."

In the past, Li You left the northwest and left Chang'an, and Li Shimin agreed to do so, which was a helpless move. In order to stabilize the court and avoid the struggle between the princes, Li You left Chang'an first. Li Ke and other adult princes also left Chang'an one after another. The court was indeed much more stable and reduced a lot of internal friction.

However, Li Shimin found that without Li You, many things would be quite troublesome to solve. It is not that it would be impossible to leave Li You, but that with Li You, the solutions he came up with are simpler and easier and more effective. Moreover, some things are indeed impossible to proceed without Li You.

After Li Ke took over Linyi Kingdom, he sent a telegram to Li Shimin. He did not bury Li You's contribution and gave a detailed report on the treatment of the plague to Li Shimin.

Li Shimin thought that Li You was just a versatile talent, so it would be more convenient to stay by your side. Moreover, those princes, you have left Chang'an anyway. They cannot return to Chang'an without their own permission.

Even if Li You stayed in Chang'an, it would not break the balance in the court and would not have any destructive effect on the entire court.

Therefore, he made up his mind to keep Li You in Chang'an.

He said: "Don't have any other concerns. No matter what you do, your father will support you.

As for the matter of going northwest to the other side, now with radio and telegrams, Cheng Yaojin, Xue Rengui and others there, I believe there will be no big trouble. Therefore, you should stay in Chang'an. This matter is decided."

Li You was still moved by Li Shimin's trust in himself. But he didn't know what Empress Changsun Li Chengqian, Li Ke and others would do? And will those around them set obstacles for themselves in the future? He didn't want to fall back into an embarrassing situation like Chang'an again.

Li You thought it would be better to explain the situation clearly to Li Shimin, so he said all these concerns in his heart.

Li Shimin said a little unhappy: "Didn't I tell you? Don't worry. Do your own thing well, and your father will be your strong backing. Anyone who causes trouble for you will solve it for you."

Speaking of this, Li You really couldn't refuse. So he followed the order and said goodbye and left.

When he returned to his residence, he thought about it and felt that he should still take the initiative to avoid misunderstandings from Empress Changsun, Li Chengqian and others. So he sent a telegram to Li Chengqian and explained the story to him. He asked him to explain to Empress Changsun.

He also discovered the telegram from Li Ke, told the story of the matter, and told his true feelings.

Li Ke is now the King of Lingnan and lives a very comfortable life. He believes that Li You is talking about the truth, and he clearly stated that he has no opinion on this matter, and hopes that Li You can create more useful things to the court in investigating things.

He once again expressed his gratitude to Li You for his help. He hopes that he can communicate with Li You frequently in telegrams when encountering problems in the future, and hopes that Li You can help him solve problems at critical moments.

Li Ke's attitude made Li You very pleased.

After he came to the Tang Dynasty, he wanted to change the tragic situation caused by the struggle between the princes of the Tang Dynasty. Li Ke was one of the protagonists of the palace fighting, but now his attitude has changed like this. It has to be said that this is Li You's efforts that have received a huge reward.

So, what kind of attitude does Li Chengqian have?

And how would Empress Changsun, Changsun Wuji and others view this matter? 8)
