"Why did Gong Li sigh?" Su Shichang asked suspiciously.

Li Jing sighed again and said: "The former Sui Dynasty's foreign conquest made the entire court panic, and every time the war was consuming national strength. ”

"That's Emperor Yang of the Sui Dynasty, the internal war must be attrition, the foreign war must be able to make money, or lay the foundation for the great development in the next few years, just spending money to fight, no matter whether you win or lose, it is a loss." Liu Mu did not politely belittle the former Sui a few words.

Li Jing asked, "So, if you conquer Goguryeo, how?" ”

"They also use levies, a bunch of sticks who can only wield sticks, and I use them to earn enough coins for our expedition sticks, and then I will beat them."

Su Shichang repeated Liu Mu's sentence on the stick and the coins of the expedition stick nine times in a row.

Suddenly, Su Shichang slapped the table violently: "Liu Concubine, the old man recommends you to be a leader." ”

Li Jing was stunned by Su Shichang so suddenly, it took a long time to come back to his senses, and slowly poured a cup of tea for Su Shichang: "Su Gong's love for talents and talent is admirable, but before this, His Royal Highness the King of Qin has recommended Liu Fei Ma three times. ”

Gong Chang Su laughed heartily after reacting, King Qin should now be renamed a saint.

The three of them were chatting, and suddenly someone banged on the door, and Li Jing ordered: "Come in." ”

The guard opened the door at this time, and Baoqin rushed in and rushed to Liu Mu's side: "Big, big thing." The Emperor is coming. ”

"What?" Liu Muxin said Li Yuan, you are not tired, you followed Lingnan before, and this will run to Saibei again, and sixty-year-old people don't know how to enjoy Qingfu at home.

Li Jing and Su Shichang immediately sorted out their clothes and trotted out to greet them.

Liu Mu also hurriedly followed.

But in front of the main courtyard garden outside, Li Yuan, who was dressed as an ordinary rich and noble, was standing there with a smile, and the little Khan of Tuli was lying in front of Li Yuan, as if he was saying something.

Li Jing and the others ran closer, and before they had time to give a salute, they heard Li Yuan say to Li Jing: "Pharmacist, hurry up and help him up on behalf of me, he wants to gather the strength of the whole clan to fight to the death with Jieli for the Tang Dynasty first, and I have received this intention." Since Erlang has appointed you to be the generalissimo of the Northern Expedition, you are in charge of these military affairs. ”

"Yes, the Emperor." Li Jing hurriedly responded.

Originally, Li Jing had already given up on the side of the Tuli Little Khan, but today he didn't expect that as soon as Li Yuan came, the Tuli Little Khan would immediately change, and it can only be said that this is the God bless Datang.

Of course, what Li Jing didn't know was that Liu Mu pulled everyone into the shares, which stimulated the little Khan of Tuli.

At this time, Li Yuan said to the little Khan of Tuli: "When we meet for the first time, I want to reward you." Oggi. ”

Liu Mu made a gesture to Baoqin: "Box No. 3, one box is coming." ”

Soon, Baoqin took a brocade box. The hug qin was not held, but handed it into the hands of a guard.

If he held the Qin and held the little Khan of Tuli, he would not dare to take it, the person in front of him who had the title of the Tang Dynasty and was the closest person to Liu Mu, he would not dare to be a maid in Baoqin.

The brocade box was opened, revealing six binoculars with adjustable copper and steel shells wrapped in fine sheepskin.

After the little Khan of Tuli thanked him, Li Jing took him away, and Li Jing had to explain the details of some strategic things to him.

A telescope wrapped in shark skin, Liu Mu took it from Baoqin and handed it to Li Yuan: "Father." ”

"It's finished?"

"No, I can only say that it can barely be used. Erchen estimated that it would take at least three years to see twenty miles. When the weather is good, I can barely see a figure ten miles away. ”

Li Yuan gave it a try, and in his eyes it was already a surprise.

It's much better than the original, not only is it costly, but it's only half as far away.

Without waiting for Li Yuan's praise, Liu Mu said again: "But Erchen still ordered someone to make a one that can be seen thirty miles away, which is not only bulky, but also very easy to break." ”

"Take a look." Li Yuan wanted to take a look.

Liu Mu ordered the men to stand guard on both sides of the city wall, and then set up the monocular, which was five feet long and as thick as a bowl. The cost of this thing is several times more expensive than the one given to Qin Qiong at the beginning, because the technology is not mature, and such a finished product was completed by luck, which is a gift to Li Jing's northern expedition.

Just looking at the assembly process, Li Yuan understood that this thing was not practical, and there was so much time for you to carefully tidy up these things when you were marching and fighting. But this represents a high-end craftsmanship and proves the value of the huge amount of research money that has been spent on the lens workshop over the years.

"It's good, remember to reward those craftsmen when you go back."

"Erchen understands."

Li Yuan helped the willow wood: "When the construction was in turmoil, you brought those soldiers who flew in the air." ”

"This ......" Liu Mu hesitated for a moment and said, "I brought it, only thirty people were brought, they were the strongest scouts, these people can fly in the air all day without falling down when the weather is good." But there is a big trouble that you will get lost if you fly far, and it is easy to lose sight of the direction. ”

At this time, there was no navigation, which is why Yanagi was hesitant to use these people.

In case that one falls in the Turks by accident, this is the leakage of Datang's high-end technology.

Li Yuan didn't ask any more, only said: "The matter of the war has been handed over to the pharmacist, and there are actually only two reasons why I came here. The first is that your second brother has just ascended to the throne, and he has no way to let go of his hands and feet when I am in Chang'an. Especially after he issued the edict of dismissal, many clans came to me to intercede. ”

"Erchen understands, it's not easy for the second brother."

"Yes, let him do it freely, and he will be a good emperor. Another reason is that I have heard Shubao's report, and Shubao thinks that the Hui people have a bold temperament and value love and righteousness. You think about it for your father, and promise them some benefits, and your father hopes that they will be with Datang sincerely. Li Yuan said another purpose for his visit.

In fact, to Liu Mu's ears, Li Yuan's trip is still paving the way for Li Shimin.

When the north is stable, Li Shimin can start the reform of the Tang Dynasty.

Liu Mu said in a low voice: "Father, what I want is not to be friendly forever, but to be Hui and Turkic, to become the Tang Hui and Tang Turks, and the Tang Dynasty is a great empire integrating many ethnic groups." It should be integrated. ”

"Blend in?" Li Yuan repeated these two words and smiled with satisfaction: "It seems that I am still old, you young people have ideas and courage, which is very good." ”

"Father, there is also a process for this integration, of course, according to your ideas, first friendly."

Li Yuan laughed heartily: "That is, you, you will really make people happy." ”

Liu Mu was very cheeky and answered: "If you can't even make people happy, how can the minister coax Princess Changping home." ”

Hahaha! Li Yuan laughed even louder.
