As Fang Yiai complained, the hot climate and strong sunshine in the desert are a big problem, but it is not difficult to solve.

The first is the dazzling sunshine.

Although Li forgot to worry about making glass now, he was unable to match the 150000 troops of the western expedition with a pair of sunglasses because of the inefficient production capacity of making glass by hand.

But this is not difficult. Just prepare black gauze and let the sergeants cover their eyes with a thin layer of gauze, which can effectively block the sun.

As for sunscreen, we can only learn from Arabs.

The head scarf made of white linen is not only sunscreen, but also windproof.

Li forgets to worry about these two things. He is going to find two veterans Niu JINDA and Xue Wanjun later to prepare the black yarn and headscarf for the sergeants. He can solve some problems more or less.

But the most important thing is the water source needed by the army to enter the desert, which Li forget worry can do nothing about.

In addition to letting the camel team bring more water, Li forgets worry and has no other way to change water out of thin air.

In this way, a very important problem is highlighted, that is, the number of camels prepared for the army is far from enough.

In order to cooperate with the western expedition army, Dunhuang county has already prepared 20000 or 30000 camels for the army and hundreds of experienced guides under the order of Li Er.

A camel can carry three stones of goods. A day's March requires a thousand camels to supply supplies.

Twenty thousand camels can only meet the needs of 150000 troops to cross the desert for 20 days.

However, after a simple calculation, Li Qieyou was shocked to find that if the camel team had to carry four-wheel carriage accessories, as well as enough water, as well as all kinds of luggage and horse materials... It seems that the remaining 10000 camels are not enough to support the 150000 army.

Unless the carrying capacity of clear water is reduced, it will be a disaster if the army loses its way and misses the few oases in the desert.

To figure this out, Li forgets worry and has no time to continue grinding his teeth with the dandies. He hurried to find Niu JINDA to discuss the matter.

Niu JINDA and Xue Wanjun, two veterans, were silent after hearing Li forgetful's words.

They have led the army for many years. They don't know how many battles they have experienced, but they have never been in contact with the desert, let alone what to pay attention to when marching in the desert.

Niu JINDA sighed, "chief manager, if you say so, it's a big problem. Now it's impossible to recruit more camel teams. Your majesty and the Imperial Hall have worked hard to recruit these camel teams for the army."

Niu JINDA and Xue Wanjun are very stubborn. They must call Li forgetful's official position, which makes him very unaccustomed. But the two veterans insisted, and he could only accept it reluctantly.

Li forgot to worry and nodded. He knew that Niu JINDA was good.

With the national strength of the Tang Dynasty, although it is not impossible to recruit more camels, it also takes time. It is not possible to recruit tens of thousands of camels in a moment and a half.

Xue Wanjun pondered and said, "if not, reduce some water. I asked the guides. There are many oases in the desert that have water sources to supply the army."

Li forgot to worry and shook his head: "I'm afraid it's wrong! If you lose your way and can't find an oasis, wouldn't you be trapped in a Jedi?"

His remark was not alarmist.

In the era of no satellite navigation, getting lost is really a normal thing.

Li Guang went to Mobei to attack the Xiongnu. Because he got lost, he almost delayed his fighter.

Moreover, the sand dunes in the desert will be blown by the wind to change their position or even move. Even those oases may be buried by dust storms. It would be too unsafe to place the drinking water of 150000 troops on the desert oasis.

Moreover, even if there is water source in the oasis in the desert, its water source scale is limited. I'm afraid it's also very difficult to provide drinking water for 150000 people.

Xue Wanjun and Niu JINDA looked at each other and nodded silently. They knew that Li forgetful was right.

The three men were silent for a while, but Li forgot his worries and made up his mind: "Uncle Niu and manager Xue, now it seems that we have to divide our troops. Manager Xue leads 20000 vanguards and 10000 baggage soldiers to go first. I lead 30000 troops and 20000 baggage soldiers to follow manager Xue. The other 30000 troops and those baggage soldiers will stay in Dunhuang County temporarily. After we cross the desert, the camel team will return, and uncle Niu will lead the rest of the troops to cross the desert."

Of the 150000 troops in the western expedition, there are only 80000 soldiers. The rest 70000 are baggage soldiers, medical soldiers and civilian men and craftsmen who are responsible for transporting logistics.

He and Xue Wanjun led only 80000 troops, and those camel teams were enough to supply the needs of the army without any problem.

Niu JINDA nodded and shook his head: "the chief manager said to divide the troops, but it is reasonable, and the last general agreed. But how about asking the chief manager to sit in Dunhuang county and lead the rear army? The chief manager is relieved, and there will be no problem with a general and chief Xue."

Li forget worry must admit that Niu JINDA's proposal is too tempting.

If you can stay in Dunhuang County, it is naturally better than eating sand in the desert.

But the temptation belongs to the temptation. Li forgets worry and can only bite his teeth and decline Niu JINDA's kindness.

As the general manager of the western expedition, it would be disgraceful for him to stay in Dunhuang county.

Li Qieyou shook his head and said with a smile, "Uncle Niu, I'd better lead the army. I think with the strength of the countries in the western regions, I can't wait for my nephew to cross the desert. Manager Xue has leveled Gaochang country."

Niu JINDA listened to what he said. It's really the same truth after careful thinking.

Whether Li forgets worry or Niu JINDA, Xue Wanjun thinks that going to the western regions is actually more like an armed March. With the combat effectiveness of the Tang army, there is no difficulty in leveling the western regions.

Li forget worry also won't think foolishly, really just hit Gaochang City, he can go back to Chang'an.

Fighting Gaochang was just an excuse for the Tang Dynasty to conquer the western regions.

After Gaochang was conquered by the Tang army, the army will certainly attack everywhere to conquer Khotan, kuizi, Wusun and other countries until the establishment of Anxi capital protectorate.

As for the pretext of conquering the western countries, it is not a trouble.

Just like the story of the big gray wolf and the little white rabbit, "I told you not to wear a hat!" is also a good excuse.

In short, the law of the jungle, Li forgets worry, but he doesn't think it's wrong to destroy the western countries under this absurd excuse.

After all, in some ways, bringing the western regions under the jurisdiction of the Tang Dynasty may not be a bad thing for the people of the western regions.

Moreover, Li forget worry is not a "virgin", and there will be no psychological burden.

Now he just wants the army to quickly pass through the Tengger Desert, conquer Gaochang, take Gaochang as the center, lay a large enough land, establish a perfect logistics supply line, and then return to Chang'an.

After the three discussed, Niu JINDA and Xue Wanjun went to prepare themselves.

A few days later, the western expedition army, who had enough spirit, began to pull out of the camp and move towards the vast desert
