A team of fast horses left Chang'an City and ran out of the speed of sprinting.

After one-third of a quarter of an hour, the team arrived at the post station, and the leader immediately shouted: "Six, urgent report."

The people at the post station used the fastest speed to pull out six horses, and six people changed their horses, and they accelerated their start, and more than a dozen breaths reached the fastest speed of the horse.

Another third of the moment, the second station arrived and shouted the same.

There were many good post stations in Jingzhao Mansion. In half an hour, six people who were eager to report ran out for more than 110 miles.

This is because changing horses is delayed, otherwise it will be faster.

The person who sent the emergency report did not feel tired at all, but was very excited and too satisfying.

An hour passed, and the news rushed out of the boundary of Jingzhao Prefecture and ran northwest.

The stations in Anxi Protectorate were not all built, and the team of senders ran for eleven days.

After running for more than half of the way, I met Shiliyiyi.

Otherwise, if you have to run for half a month, if you change them to ten miles and one post, it would be slow to get to the place in six days.

The current team is the way they came to Liangzhou, which is more than 1,700 miles away.

At this time, there were still two hours before dark, and the team wanted to arrive in Qinzhou when it was completely dark.

Then, when it was dark, I picked up a kerosene lamp and slowed down from Qinzhou to travel at night, and arrived in Jincheng, Lanzhou in the second half of the night.

At night, I walked through the Water Station to cross the Yellow River. After getting ashore, it was still slower, and it was almost dawn.

After running for more than three hours, at about noon, I delivered the letter to Liangzhou.

It’s so fast, the longer the day, the faster the speed. People are really tired from running for a day and a night, but they can persist.

The six people kept whipping, not afraid of exhaustion at all. The horse probably didn't get enough to run, so they went to the next place.

The person who sent the letter from Anxi Protectorate was sleeping soundly. He didn't eat, but just drank a bowl of soup.

They changed horses but not people. They ran for eleven days and twenty people, afraid that someone would intercept them on the road.

They were asleep, and apprentices from the Imperial Medical Department were massaged to relieve muscle fatigue.

I didn’t have this treatment before, and everyone didn’t think that the person who sent the express newspaper needed a massage, just take a nap.

Now it has changed, it must be good to the soldiers. Anyway, the apprentice needs to practice, and there is a master at the side to give guidance.

Normally, it is still uncomfortable to sleep and it takes several days to take a rest.

Now everyone's brows are stretched, but they don't snore. They are massaged. The snoring person stops as soon as they touch it.

They had straws inserted into their noses and oxygen bags to replenish oxygen.

The apprentice who was massaged changed the towels and wet towels.

The towel that was replaced was thrown into the basin of water. During a few breaths, a basin of water turned black.

The master is teaching the person who is pressing points, lines, and surfaces. The body of the person who is reporting the message is just right.

If you didn’t press a place, the towel was opened, and that place would be darker than the side.

People who are sleeping hard still don’t know that they have enjoyed an oxygen massage and even have a bath.

"I am as expected, Guo Zhiyun will be able to launch an offensive in five days." Bi Gou placed a map in front of him, a map given by Li Yi.

Su Feng looked at it together: "Looking at it for two days, unless the local army is not ready."

"This is a mountain, three mountains, Guzang Nanshan, Jinshan, and Daxue Mountain, you need to take a detour." Bi Gou pointed to the name of the mountain range on the map and said.

He asked someone to take a thick, big dictionary-like thing and look for it.

"Look, there is an introduction to the mountains, relative heights, and river valley situation." Bi Gou asked Su Yang to look at it.

Su Feng took a look and nodded: "It takes five days. After going around, you can make a breakthrough."

Song Jing pointed to the map: "There are troops stationed in the west of Daxue Mountain. This year's supply is good. Some troops are circling around. The troops west of Daxue Mountain fight directly. The news spreads for two days."

"The positions are all very good." After Su Feng finished speaking, he saw the two of them looking at him in surprise and laughed awkwardly.

He felt that he was idiotic when he was speaking, so would the governor not know the local situation?

Ensure that you can choose a place that is easy to defend and difficult to attack, such as the previous battle of defense of Songzhou, where there is a river behind Songzhou. If you have to cross the river after defeating Songzhou, you will have to fight.

If you don’t fight, just cross the river. Songzhou sends troops to chase you and fight, and you can cross the river halfway.

Therefore, if you cannot catch Songzhou in Tubo, you will never cross the river, otherwise you will be attacked by the Tang army.

If there was no river, the cavalry rushed over and there would be no time for Songzhou to chase him, so they would go around the city.

When Tubo attacked Liangzhou, he first attacked the garrisons of Daxue Mountain. If he wanted to attack the garrisons of Daxue Mountain, he had to cross a river called Haomen River.

Haomen River is the mainstream of Huangshui River, and Huangshui River enters the Yellow River.

This is the position you choose, let’s fight. After that, you will still fight halfway through, even if you pay a heavy price, you will defeat the army of the Tang Dynasty.

After that, will you climb over the snow-capped mountains? If you don’t climb over, take a detour. If you go around, the Longyou Jiedushi, which is very close to you, won’t you hit you behind?

In fact, there is still an army stationed in the west of Haomen River, and the entire place cannot be defeated.

That's why the Liangzhou poem written by Wang Wei was created, where the desert was lonely smoke and the long river was round.

On the beacon tower of the Tang Dynasty, lonely smoke represents peace, and a pillar of smoke rises to indicate that there is no war.

Song Jing said two days ago that Liangzhou sent the attack orders to the troops west of Daxue Mountain and sent troops from there.

Su Feng figured it out, suddenly was stunned, and after a moment, he spoke out: "According to this point, Li Yijue has made great achievements."

He thought of a steamer, which was easy to reverse the current, and even from Chang'an, he could deliver things to the front even through the Yellow River.

He finally knew how powerful the ship was, and what the Hukou Waterfall could be navigated.

The ship is slow, but it can be built more and delivers things to the front continuously.

Is there any local specialty in the area ahead? I load it on the ship and come back downstream.

Not only did it provide supplies to the front line, it also solved the living conditions of local people and ensured that the income of the people was greatly increased.

The local things cannot be transported out, so they are thrown away, including fruits, animal skins, and wild medicinal materials.

What is needed is an official team that can make profits from the Yellow River and help the frontline a lot.

"What is Xiao Yi's credit for working for his own family? When can he build a bigger kite and fly the things directly over, I will be convinced."

Bi Gou started to show himself again, I am the most powerful.

...

"San brother, look, there is less than thirty miles between these two rivers. If you dig it up and connect it, you don't have to walk through the Hukou Waterfall."

Li Yi showed Li Longji the map in Zhuangzi. The Long River is connected to the Wei River, and there is a river above it.

That river connects to the Yellow River and has a canal mouth.

It is a much closer distance than the Hukou Waterfall, and the artificial canal.

Li Longji pointed to the location on the map: "There are mountains."

"It saves more effort when you have mountains. The valley naturally flows, opening up and down. There is no need to dig the valley. The river is not very wide, so it is absolutely fine to take a ship."

Li Yi is not afraid of mountains. There are mountains and valleys. How many trunks are there in Xinjiang? The mountains across the mountain blow it up.

"Is there any danger?" Li Longji worried that someone would die.

"Death-inmates, they either die or work. When they are dug up, the death penalty will become imprisonment. They will earn it no matter how much they say." Li Yi has someone to choose.
