"I don't know if we can occupy the entire Yellow River basin this time." Li Longji came back at noon today.

After eating, he wandered around to eliminate food, and Li Yi thought about Tubo.

In fact, it was Li Longji who was imagining, Li Yi didn't.

"Zhaling Lake and Ngoling Lake are the largest freshwater lakes over there, and if Tibet loses two lakes, it will lose even more land."

Li Yi mentioned the importance of the lake, and Tubo would be desperate.

At present, many of the soldiers in Tibet are tribes that obey the orders of the Tibetans, and they have no will to fight.

Tubo's own troops are still very capable of fighting.

There is a record in the Old Tang Dynasty Book: 'Go Lu Bo, blowing the lili and beating the drum is a play, and the bow and sword do not leave the body.

The strong and the lowly old, the mother worships the son, the son is the father, the one who goes in and out is in the front, and the old man is behind.

The military order is serious, and in every battle, the front team dies, and the rear team advances. Heavy soldiers died, and the evil disease died. The successive generations of war did not, thinking that the first door.

Those who are about to be defeated, hang the fox's tail at the head, show their cowardice like a fox, and the crowd will be favoritism, and their vulgar shame will be the next death. ’

It is said that the Tibetan people like to play chess with a grid, and the Li refers to the conch, blows the conch and beats the drum to play.

The prime of life is important, the old are low, the status of the mother is not as high as the son, and the son is arrogant in front of the father.

When they walk, they are all young people in front and old people in the back.

When the war is fought, the front is gone, and the back is advancing, and those who die in battle are the most important, and those who hate to die of illness are dying in battle, and every generation has died in battle, and this family is Jiamen.

Then there is the humiliation of the vanquished, which is second only to death.

This is the serious soldier of Tubo, who is strong, who dares to fight, who is respected.

If the two freshwater lakes at the source of the Yellow River were occupied by the Tang Dynasty, would they agree?

Li Longji stopped: "How will Guo Zhiyun respond?" ”

"Look at the battle situation, the battle situation is favorable to Datang, he should go to occupy it, and then count on the transportation of weapons in the back."

Li Yi guessed that if it were him, he wouldn't be able to think of any good way.

The area that needs to be defended is too large, and the troops in Tibet are fast.

In the absence of a fortified city to defend, the role of the military fortress is small.

But as long as there are enough monkeys and explosives bags, the Tibetan army will not be able to find a good way.

Li Longji stepped again: "Guerrilla, fight cavalry." ”

He thought of what the Tibetans would use to deal with it, scattering the cavalry and not forming together.

When the wind is in the upper hand, arrows are fired at the military village from a distance, including catapults.

Use the Sky Monkey to blow up the catapult to see who can support it, the catapult is money, and the Sky Monkey is also money.

However, the explosives package is easy to use, and the explosives package is used for mines, and the pipes are buried and buried outside the stockade.

Look at the enemy's cavalry running pattern and find the right time to ignite.

"There's also night fighting, I can't give all of our hot air balloons night vision devices. Put torches outside, you need to burn all night. Prepare more dried fruits, carrots, and pepper flakes. ”

Li Yi added that he was a person from the Tubo side, and he couldn't defeat the Tang scouts during the day, and there was no way to attack at night.

You can storm the military village at night, and it is impossible to put many people in a military village, concentrate superior forces, and fight a village while it is dark.

Your side will suffer heavy casualties, and at least you can knock down the stockade.

If you don't fight, it will be eaten by Datang, and there is still a chance to fight.

They even sent some soldiers to fight the villages, and some soldiers to kill the people and livestock grazing along the Yellow River and on the grasslands by the two lakes.

It's not a Shanhaiguan there, so there's no danger to defend.

Troops were transferred from behind, and one lake was more than 4,270 meters above sea level, and the other lake was more than 4,290 meters above sea level.

The soldiers in the back do not live in the plateau area, how many non-combat attrition will there be?

In normal times, the soldiers with good physique in the back may be able to withstand it, but they need more oxygen support to fight, and they didn't run many steps, and they fell first.

That's why his country had so few troops when it faced countries that didn't like to build toilets.

Especially in the beginning of the war, the local ethnic minorities have not yet fully integrated into the big family of the motherland.

Unlike later, most of the people who guarded there were ethnic minorities, and the rest of the soldiers had to be able to adapt to the plateau climate first.

For example, in the Wakhan Corridor, where the average altitude is more than 4,000 meters, the national army guarding it dares to say that it will not let one go out or let one in.

That's because people are Tajiks, highland peoples.

If there is a slight disaster there, the central government will be anxious and must help, counting on people to guard the border.

If altitude sickness is really so easy to overcome, why bother training on Taibai Mountain?

The amount of exercise in tourism is not the same as the amount of exercise in battle, go to the Potala Palace and try to run a 5,000-meter run there.

Li Longji's expression was solemn: "Transporting cement, no, build a kiln in the local area, and send Yulin Fei to guard it." For the time being, they will not exchange livestock, only the people of the Tang Dynasty. ”

"However, when they were asked to burn cement, they would not know the ratio of raw materials.

Leave them away while the raw materials are transported and loaded, and then let them come back when it's time to burn.

In fact, it's useless to know, they don't know where there is coal, and when we take some places, I will point out the location.

There is a place where the coal looks like a hill, and when you dig up the ground, the coal will flow down. ”

Li Yi felt that he was thinking too much, and told Tubo how to burn cement and what to burn in Tubo?

Wood? Hay? Cow dung?

Even if you don't hesitate to spend a lot of firewood to burn hard, how much cement can you burn? If you have that time, it is better to take ready-made materials directly like repairing the Potala Palace.

Hearing what Li Yi said, Li Longji suddenly thought about it: "Yes, others don't have coal, they can't plant well, the smelting process is not good, and they will burn cement?" ”

He smiled: "Brother Yi, let go of the cement factory and build it in various places, others are willing to learn and learn, at least we Datang people use it first." ”

"In that case, I can take 4,000 taels of honey, no, I will pay 20,000 taels of honey."

Li Yi instantly thought of the Wa Kingdom, and if there were more cement factories built, it would be impossible to keep it secret.

I don't care about the four thousand, and all the people who take care of the cement factory don't care either?

It is better to give 20,000 yuan a chance to meet, and then lead the Japanese people to visit the cement factory, and the cost of the visit is ......

When there was no cement, there were castles in the same country.

Without cement, wouldn't the Great Wall be repaired?

Li Longji looked at Li Yi and patted Li Yi on the shoulder: "With you, we Datang will not suffer." ”

Li Longji really couldn't figure it out, talking about the matter of Tubo, how did Li Yi think of making money from the Japanese Kingdom.

……

The envoys of the Wa Kingdom were always waiting, waiting for Li Yi to see them.

It's just that the left can't wait, and the right can't come, Li Yi doesn't seem to care about the four thousand pieces of honey.

"Is there no one to help deliver the message?" Shimodo Zhenbei began to be suspicious, suspecting that the people from Honglu Temple did not go to Li Yi.

"Less money?" Junichiro Takaki followed.

"A hundred is less?" Fujiwara Mayo believes that according to the current purchasing power of Chang'an in the Tang Dynasty, a hundred is a lot.

"Get him a meal." Abe Nakamaro gave the most direct way, and asked him sideways when he was eating.
