Datang: I was tricked by the system

"Your Majesty, what is the secret weapon you are talking about? This mountain range is so huge that it would take too much manpower and financial resources to dig it open." Lu Ziyu rode on a horse and walked side by side with Li Yi, watching the mountains while walking. Asked looking at the mountains in the distance.

She really couldn't think of anything that could easily cut through the mountains. Even the mechanism researched by the Hou Mo family would not have such power.

This time, they didn't go back the same way, but planned to follow the route planned by Li Yi, and it was convenient for Li Yi to make some modifications to the drawings according to the actual situation.

Hearing Lu Ziyu's words, Li Yi smiled mysteriously, "You will know when the time comes. Although it is difficult to dig mountains, it can save a lot of time when you actually walk."

When marching and fighting, fighter planes are also very important.

Once this road is repaired, the benefits will be unimaginable.

What he wants to do is not just to dig tunnels, but to build a wide and flat concrete road, similar to the highways of later generations, but the specifics have to be determined according to the actual situation.

As for the secret weapon, it is actually just something like explosives.

Li Yi didn't want to use these things for war, but there was nothing wrong with digging roads.

Of course, the specifics have to be completed after this trip, and after the complete route has been planned, then the people of the Mohist school will work together to develop a suitable machine.

It is not impossible to rely on manpower alone, but it is too difficult.

Departing from Longyou, Li Yi took Xue Rengui, Shan Xian, Lu Ziyu and others, and arrived in Mongolia after half a month. Ge Qing had already received the news and arranged for reception.

Along the way, Li Yi changed the names of Tuyuhun, Tubo, and Western Turks directly according to the names of later generations.

Qinghai, Tibet, Xinjiang, and the original East Turkic territory were changed to Mongolia, with provinces as units, divided into cities and counties, and assigned personnel management according to levels.

After five years of development, Youtang has no shortage of these talents. Along the way, after Li Yi confirmed these, Jia Xu and Chen Jinbai directly selected a group of talents from Youtang's academy who had just graduated and admitted them, and arranged them Take office.

Where the route is determined, after the officials take office, people can be arranged to start work.

"Reporting to Your Majesty, I have just received a letter from the Dahe family, please read it."

Ge Qing knelt on the ground and said, originally this news was to be sent back to Youzhou, but Li Yi had already come in person, so naturally there was no need to send it back.

Li Yi took the letter, opened it and read it.

Frowning lightly, he asked, "Did the Dahe family make any changes?"

"I have been keeping people watching the border, but nothing has changed." Ge Qing replied truthfully. With the development of You Tang, more troops were stationed at the border, in order to prevent the recurrence of something like Xue Yantuo last time.

At this moment, upon hearing Li Yi's question, Ge Qing's face became a bit solemn.

Xue Rengui and Shan Xian looked at each other, then looked at Li Yi and asked, "But what's the problem with the Dahe family?"

"That's not true, it's just that they don't want to pay tribute to Datang, and want to switch to me, Youtang."

Li Yi said lightly.

"Why is this?"

"The weasel must have no good intentions to pay a visit to the chicken."

"Not only that, after half a month, they will send a mission to bring the daughter of the Chang Mohui of the Dahe Clan Alliance to marry me, You Tang." Li Yi added nonchalantly.

"And relatives?"

Both Xue Rengui and Shan Xian were very surprised, "They are not willing to pay tribute to the Tang Dynasty, so why are they willing to marry the alliance leader's daughter? Isn't this not worth the candle?"

Shan Xian nodded, "There are indeed some problems. Could it be that they feel that Datang is far away from them and out of reach, so they shifted their attention to Youtang?"

"It's also possible that I, You Tang, is powerful and want to benefit from my You Tang."

Li Yi took a sip of the buttered tea on the table, and said, "Don't bother to guess, what kind of medicine they sell in the gourd, you will know when the time comes."

As soon as Li Yi finished speaking, a soldier came in from outside the tent, clasped his fists and said, "Your Majesty, a group of foreigners came outside who said they were the envoys of the Dahe clan and wanted to see Mr. Ge."

"messenger?"

The expression on Li Yi's face was a bit playful.

"Let them come in." The letter said it would take half a month, but they came at this time, it seemed urgent.

Not long after Li Yi made arrangements, the guards came in with a group of emissaries wearing left lapel gowns, round collars and narrow sleeves, and weird hairstyles.

Shan Xian and Xue Rengui were very surprised when they met the people of the Dahe Alliance for the first time, especially when they saw their hairstyles, they couldn't help laughing.

The hair on the top of these people's heads is all shaved, and only a small amount of hair is left on the temples or the forehead for decoration. Some have a row of short hair in front of the forehead; Hair is trimmed and arranged into various shapes before falling down to the shoulders.

It looks really uncomfortable.

"I didn't expect people from the Dahe Alliance to look so strange."

"Well, it's a little...funny..."

Shan Xian and Xue Rengui whispered.

Li Yi took a look at them, but he was not surprised. The Dahe Alliance is mainly composed of Khitan people, and their customs are like this, so there is nothing surprising.

"Your Excellency must be Mr. Ge." The leading man saluted Li Yi and said in Chinese that was not very fluent.

Ge Qing stood up and said to the leader: "Ge Qing from a certain family, the person in front of you is His Majesty Yihuang from Youtang."

The man was shocked when he heard this, and then quickly saluted Li Yi.

"Xiao Ye pays homage to His Majesty Emperor Yi."

Originally, they just wanted to meet Ge Qing and let Ge Qing send a message, but they didn't expect Li Yi to be here, which saved them a lot of trouble.

Li Yi nodded, "I don't know what you are talking about when you come to my Youtang?" Without friendship, Li Yi didn't bother to talk nonsense with them, so he asked directly.

Xiao Ye was stunned for a moment, and then said respectfully: "Xiao Ye was ordered by the leader of the alliance to come to see His Majesty. My Dahe Clan Alliance is willing to make friends with His Majesty and pay tribute every year, and the leader of the alliance is also willing to send Our princess is married to Your Majesty."

Li Yi nodded, playing with the teacup in his hand, and asked after a while: "What about the conditions?"

Li Yi never believed in the fact that there was nothing wrong with the heavens. The Dahe Alliance suddenly wanted to pay tribute to Youtang and marry the alliance leader's daughter. If he had no intention, he would not believe a word.

"This……"

Xiao Ye didn't expect Li Yi to be so direct, which made it difficult for him to ask.

"There are no conditions, we are just willing to make friends with His Majesty and become allies."

The arc of Li Yi's mouth widened a bit, but the coldness in his eyes became more and more serious, "If this is your sincerity, please go back."
