Xu Qilin didn’t say what a national pillar industry is, what is related to national economy and people’s livelihood, and what is export and foreign exchange entrepreneurship? People in the Tang Dynasty didn’t understand it either.

And it is naturally his only one who can see such a broad prospect from a small cotton and think so far.

Even if His Majesty Li Er allowed him to grow cotton, he thought of the common people having cotton coats in winter and single coats in summer.

The three-day picking finally ended, and the bundles of cotton were transported to the workshop. The migrant workers who had enough food and drink and made money also returned home to live with satisfaction.

However, local people who grow cotton are not idle yet. The cotton poles can be chopped and composted, and will be high-quality biological fertilizers; they can also be fermented and become livestock feed; and they can even be made of industrial paper.

The technology of orange stem and weed composting is probably the most widely used. From the large number of printing of "Practical Agricultural Books" in Dayingku this spring to the court's distribution to local officials, many places have begun to be used in the territory of the Tang Dynasty.

Coal is also gradually being promoted everywhere, which greatly reduces the use of orange stems as firewood, which is the lowest utilization value.

The changes were not obvious at the beginning, with few farmers using them and immature operations. However, with the widespread application, the yield of grain per mu of Datang will reach a new height in three to five years.

This does not count the other new technologies and diversified operations involved in the farm book. If you master it and apply it well, farmers' income will be higher.

The harvest of cotton means that Xu Qilin has completed another major event this year. Although he is going to go to Gaochang with the army, that will happen next year.

His Majesty Li Er had just issued an order, ordering Hou Junji to be the chief general of the Jiaohedao marching army, and his generals including Niu Jinda, Xue Wanjun, as well as ethnic minority generals Ashinaser and Qibirheli to begin mobilizing the government troops and ethnic minority vassals.

Although the imperial edict was issued, the transportation and mobilization capabilities in ancient times could not be overestimated. It would take at least several months for the 150,000 troops, plus 50,000 or 60,000 civilian craftsmen to gather all of them and store enough food, grass and supplies.

In other words, it will be next summer to formally dispatch the confrontation.

Xu Qilin calculated very clearly, but the arrival of His Majesty Li Er's letter gave him a discount on his enjoyment time.

As the important place in the Hexi Corridor, Ganzhou must pass through the army that conquered Gaochang. Some preparations must be done, such as the transfer, transportation, storage and storage of grain, grass and materials.

His Majesty Li Er did not have a clear rule, but just asked Xu Qilin to plan and prepare the corresponding equipment and supplies for the army.

In addition, the management and management of other places in Hexi will be smoother if they can develop like Ganzhou, conquering Gaochang and controlling the Western Regions.

Xu Qilin agreed with this. He agreed to take office before because of this consideration.

But his official position was in Ganzhou, and his development in the first year was crucial, and he couldn't leave his body and care about other places. It happened that His Majesty Li Er asked, and he was not stingy with his intelligence.

To the west of Ganzhou is Suzhou, Jiuquan, Dunhuang, Shazhou and Guazhou in later generations. It is the starting point for entering the desert Gobi and attacking Gaochang.

To the east is Liangzhou, the Wuwei area in later generations, which is the main throat entering Guanzhong.

Xu Qilin felt that the stall was too big and too much was not suitable, and the results would not be effective quickly. The main reason was the population, and it could only be done by one place.

Needless to say, Jiuquan was a famous irrigated agricultural area in the northwest inland, and it was the most important commercial grain base and concentrated economic crop production area in the northwest region.

As long as there is enough manpower, grain and cotton to grow in large quantities, it is enough for this place to become rich and develop.

As the gateway to protect Chang'an and control the Western Regions, Wuwei has been the military and political and cultural center of the northwest region for a long time. It has been a major center for trade and trade between China and the West in the Han Dynasty.

This point is similar to Zhangye, but in later generations, Zhangye had Danxia, ​​Jiuquan had satellites, and Dunhuang had Mogao Grottoes. But when it comes to Wuwei, they can't remember anything that can be found.

Of course, if the Wuwei of later generations was still called Liangzhou, the well-known "Liangzhou Ci" might have become a place name tag.

But now, Xu Qilin has thought of a way to make Suzhou and Liangzhou develop leapfrog. Of course, including Ganzhou, how can you not consider your own place?

That’s right, it was just taking advantage of the opportunity to conquer Gaochang to invite tens of thousands of soldiers to reclaim the land and plow the spring farming.

It is not difficult to operate. Let the soldiers of the palace seize the time and arrive at Suzhou, Ganzhou and Liangzhou before spring plowing. After farming, they will leave the customs and head towards Gaochang.

Tens of thousands of Guanzhong soldiers were all from farmers, and they could cultivate hundreds of thousands of acres of land in just a few days.

Don’t think that these hundreds of thousands of acres of land are contributions to the local area, and are also extremely beneficial to the conquest of Gaochang’s army.

You think, the conquest army must carry at least several months of food and supplies, and cannot always think about putting food on the enemy, that is the only way to ensure the insurance.

The war will end in the summer and it will probably be after autumn. This is still an optimistic estimate. At that time, the food in Hexi will be harvested and the supply will be provided nearby. Wouldn't it be more convenient and faster, and it can also reduce the transportation volume of the army.

Xu Qilin believed that His Majesty Li Er could agree, but he still calculated and listed the estimated data. It not only supported the army's combat in the Western Regions, but also provided long-term garrisons in the Western Regions.

This is not only an immediate consideration, but also involves the Tang army's strategy in the Western Regions. It is just to let tens of thousands of soldiers come early and do farm work for more than ten days.

How could His Majesty Li Er not understand such a simple input-output ratio? Maybe he would also intend to leave the government soldiers in Su, Gan and Liang after the war, and settle down on the spot!

As for the specific development of Su and Liangzhou, Xu Qilin thinks that Ganzhou's experience can be completely referenced. Combined with the local characteristics of Su and Liangzhou, it is a good answer.

Xu Qilin thought and wrote, but suddenly stopped writing again. He felt that he had replied all of them so quickly, which seemed very unserious. One place has its own characteristics. If you don’t go to investigate or do not conduct on-site investigation, isn’t it too perfunctory?

Although I know that these are correct, others seem to be working behind closed doors.

After thinking for a while, Xu Qilin only reported the matter of asking the soldiers to participate in spring plowing. He would leave other suggestions first and wait for a while before posting them.

It’s good to take advantage of the cool autumn weather to visit Suzhou, and it’s just a tourist.

Thinking of this, Xu Qilin couldn't help but smile, turned to Scarlett and said, "Closing it out, and taking you out for a trip while it's not cold or hot."

Scarlett agreed happily, just so obedient.

Ajiani blinked her eyes, as if she didn't mean to take her. After a while, she came over and brought the skinned apples to show her respect, and asked with her smile: "Alang, can you take me with me too?"

Xu Qilin looked at him with his eyes slanted and said, "Be careful when eating outside, don't embarrass someone."

"It must, it must. Alang is at ease." A Jiani nodded repeatedly, but she always just agreed and forgot her temperament when she turned around, which made Xu Qilin have no tricks.

…………………

Yumen Pass was first placed when Emperor Wu of Han opened the Western Regions roads and set up the four counties in Hexi. It was named after the roads when jade was imported from the Western Regions, and it belonged to the jurisdiction of Dunhuang. Another important pass, Yangguan, was also in Longle County, Dunhuang.

At that time, the Central Plains and the Western Regions all took two passes, which were important military passes and major traffic routes on the Silk Road.

One is "the spring breeze does not cross the Yumen Pass", and the other is "I advise you to have a glass of wine", which means that after passing these two passes, it is desolation and bitter cold.

Dunhuang, also known as Sand Case, vividly illustrates the characteristics of this place: an oasis in the vast sandy beach.

It is said that the energetic Huo Qubing defeated the Huns and occupied the Hexi Corridor, and the pursuit stopped here. As a result, there was a very meaningful name - Grand Glory, namely Dunhuang.

But from ancient times to the present, even an important pass faces a major problem, that is, desolation, which can be described in one word - bitter cold.

Yellow sand is everywhere, deserted, and even wild animals are rare. If Wang Fangyi hadn't been interested, Xu Qilin would have been too lazy to go so far.

"Next year, thousands of troops will come out of the pass and conquer Gaochang." Wang Fangyi was a little excited and excited, pointing at the vast sea of ​​sand, as if he saw the large army marching to cover the sky and the sun.

Xu Qilin shrugged his shoulders and tidied up the curtains that blocked the wind and sand. The image was a bit fictitious, but it didn't get confused or eat sand!

In fact, he has another purpose here, but it is not known to Wang Fangyi.

"I've seen it, let's go to Yumen County!" Xu Qilin turned to the official and guide sent by Suzhou and said, "Is this still the name?"

"Return to Xu Cheng." The official immediately bowed his hand and replied: "Yumen County was abolished in the first year of Zhenguan and is now called Kuaiji County."

Xu Qilin nodded and said, "It is said that stone paint is produced there, also called stone fat water, but it is true?"

Stone paint, stone fat water, or oil, was originally discovered in Yumen County, Suzhou. According to the Tang Dynasty County Chronicles, stone paint, stone fat water, and water greasy water floated on it, like lacquer, and was made of paste trucks and lamps, which was extremely bright.

From the Han Dynasty to the Qing Dynasty, local people used oil to light lamps in Yumen, Jiuquan and other places.

By the Song Dynasty, oil was even processed into a solid substance, called a stone candle. It was lit for a long time, and one stone candle could support three candles.

However, because the smoke produced by oil combustion is relatively thick, that is, "everything is dark". Therefore, it has not been widely used.

Of course, ancient oil did not have any high-tech mining technology, and the people basically "scrape oil". They used grass or cocktail hair to scoop on the water and then put it in cans.

Xu Qilin didn't want to exploit oil on a large scale, nor did he have the technology or tools. However, it is also very useful to acquire some.

"What Xu Cheng said is not bad." The official said: "There are mountains in the south of the county, and the stones are filled with springs, which are extremely bright."

The water and oil were mixed, Xu Qilin touched his chin and had some thoughts.

Wang Fangyi finally appreciated the scenery of the desert, turned his horse's head and came to Xu Qilin. He heard him pick up the stone paint and asked curiously: "Xu Cheng, what's strange about this stone paint?"

Xu Qilin smiled, clamped his horse's belly, and said as he walked: "If it can be mined in large quantities, it will be of endless use. But now it seems that it is not practical. I want to buy a batch and study it first."

Wang Fangyi nodded and said, "I haven't heard of it yet, let alone seen it, which is just open to my eyes."

In the leeward in front, two slender women rode on horseback and waved to Xu Qilin.

That's right, Scarlett and Ajiani have learned to ride horses. Although the horses are a little short and gentle, Xu Qilin is very satisfied with this.

…………………

Chang'an, Qianqiu Palace.

His Majesty Li Er was watching Xu Qilin's report, and his suggestions were basically approved.

There were a lot of wastelands that the Tang Dynasty had to be reclaimed, and there were in the south of the Yangtze River, and the conditions for profit were even more abundant in Hexi. However, the management and development of Hexi had deeper considerations and had extraordinary value for the exploration of the Western Regions.

Therefore, human and material resources are tilted towards Hexi, but it is not because Xu Qilin is favored.

His Majesty Li Er agrees with Suzhou and Ganzhou to develop grain and cotton and adopt similar models. The success of Ganzhou has proved that the experience is correct, and it is normal to apply it.

What's more, if the conquest of Gaochang goes smoothly, how to deal with it will be closely related to the development of Hexi.

His Majesty Li Er had not revealed his true thoughts at this time, that is, at least he had to restore the Western Regions to the state of Han Dynasty.

Therefore, many ministers believed that this was a conquest of a country that was not a minister. Due to the long road, after the victory, most of them had to restore the country and become kings like the Eastern Turks surrendered.

If Hexi is a strong backing and logistics supply base, His Majesty Li Er could destroy his country and establish a prefecture and county, and bring Gaochang into the territory of the Tang Dynasty. When the ministers gave advice, he also had the confidence and reason to refute it.

Once Gaochang is incorporated into the territory, it will have to fight against the Western Turks for a long time in the Western Regions. It is not possible to have fewer troops stationed. His Majesty Li Er is also thinking about rebuilding the Western Regions Protectorate in the Han Dynasty!

Moreover, His Majesty Li Er had already thought of his name and set up the Anxi Protectorate Palace after he captured Gaochang.

Therefore, Xu Qilin's report was undoubtedly approved. As for what Xu Qilin said, he set out to Su and Liangzhou for investigation and investigation, His Majesty Li Er praised it even more.

This kid is quite concerned about doing things, doing it as he says, not afraid of the wind and sand in the northwest and the hard work of trekking.

His Majesty Li Er finished his approval in the memorial, picked up another memorial and pondered.

This memorial was written by Suzhou Governor Chen Fangbi, who requested to be released due to illness. Just like Ban Chao was in the Western Regions for a long time and missed his hometown when he was old, Chen Fangbi hoped to return to his hometown alive before he died.

After thirty years of his hometown, I only wish to be born in Yumen Pass. Compared with Ban Chao, Chen Fangbi is far inferior.

But His Majesty Li Er was not angry. Chen Fangbi's memorial was too timely. He was worried that there was no way to go, and a sticky bean bag fell from the sky.
