"Father, do you understand the role of Beiting and Anxi to understand the importance of the river." Wang Fei interjected obediently.

"The children can be taught!" Wang Zhengjian happily stroked his long beard and continued: "The Beiting and Anxi armies are sitting in the west of the city, and the heart of Guanzhong is almost unheard of by swordsmen. However, Mobei can pass through Jinshan and Yili River into the river, and outflank Beiting from the northwest; Tubo can take the big and small Bolu and besiege Anxi in a roundabout way. If the Tang Dynasty stops at the west of the moraine, although it can suppress Mobei and Tubo, it cannot really weaken it. Only by completely controlling the river and completely cutting and encircling Mobei and Tubo can we forever stop the northwest border troubles and sit back and relax! ”

"This is also where our army has repeatedly fought with the Western Turks and Tibetans in the Suye River Valley for decades." Du Huan saw that Wang Zheng finished speaking, and added a sentence in time.

"I'm afraid it's an unexpected change when the big food is involved, right?" Wang Fei asked.

Wang Zheng glanced at Du Huan and nodded: "For the Great Food Country, our army's knowledge is indeed limited. When it first encountered the Great Eclipse decades ago, the political affairs hall thought that it was just a small country like the surname Zhaowujiu. Later, I learned that Dashi is also a big country with a territory of thousands of miles, which is really shocking. It's just that Hezhong is too far away from Chang'an, and in the hearts of the military and people in the mainland, they always think that Dashi is just a small country. In fact, looking at Moxi, that is, Liulang, he really understands the big food, and other people, including a certain one, are only half-understood. ”

"I don't deserve such praise from Duhu!" Du Huan hurriedly said: "I just think that although Huaxia is big, it may not necessarily be the center of the world. In the far west, there seems to be a vast expanse of land and country. We can't rest on our laurels and sit back and watch. ”

Wang Fei saw that Du Huan had such insight beyond the times, and couldn't help but sigh secretly: "It is really commendable that Judge Du was able to break through the limitations of Sinocentrism in the Tang Dynasty and see the world with open eyes!" ”

When he paid attention to the history of the Tang Dynasty in his previous life, Wang Fei's attention was on the emperors and generals, and he was not familiar with Du Huan's experience. He did not know that if the original time and space were developed, Du Huanhui would be transferred to the Anxi Protectorate by Gao Xianzhi in the tenth year of Tianbao (751), and participated in the Battle of Talas with the army.

Gao Xianzhi was defeated by Abu? After Muslim, Duhuan became a prisoner of war for the Great Cannibal. Because he can speak the language of the big food and has extraordinary knowledge, he is valued by the big cannibals and avoids the embarrassment of becoming a slave.

In the following eleven years, Du Huan lived and traveled in the country of Black Clothes and Great Food, and successively arrived in West Asia, North Africa and other places, until the first year of Baoying (762) returned to Guangzhou by merchant ship and returned to the Tang Dynasty.

After returning to Chang'an, Du Huan compiled the travelogues recorded for many years and wrote the book "Jing Xing Ji", but unfortunately it was lost later.

Only in the "General Dictionary" (written in 801) compiled by his uncle Du You quoted more than 1,500 words of the "Jing Xingji", so that future generations learned that during the Tang Dynasty, Chinese had traveled to North Africa. After that, when Chinese arrived in Africa, it was more than 600 years later, when Ming Chengzu sent Zheng He to the West.

However, the focus of traditional Chinese historical records has always been on the clothing, food, and daily life of the emperors and generals and the open and secret battles in the court.

Therefore, Wang Fei didn't know that this broad-minded and quick-thinking Judge Du should have had such a magnificent and ups and downs life experience. Of course, after the emergence of the traverser, the trend of the entire history is slowly but firmly deviating from the original track, and the trajectory of Du Huan's life will also change......

"The eastward march of the Great Food has made the already complicated chess game in the river even more chaotic. A few years ago, Mobei was divided and unable to look westward. Playing against those in the river, the Tang Dynasty, Tubo and the Great Food! Wang Zhengjian followed Fang Cai's train of thought and continued: "Because the land in the river is too far away, our army cannot afford to stay for a long time, so Fang supported the Tuqi Shi people to resist the Great Food and Tibet. Later, the ambition of the people gradually sprouted, and they wanted to get rid of the shackles of the Tang Dynasty; The big cannibals took the opportunity to encroach on Zhaowu and Tubo to press Xiao Bolu step by step. Such a change of situation led to the fact that our army was in a difficult situation in the river. In order to break this situation, the Sage and the Political Affairs Hall had the Anxi Army's expedition to Xiaobolu and the Beiting Army besieging Broken Leaf City, blocking the road to the north of Tubo to the middle of the river, and also eliminating the hidden danger of the Tuqi Shi people on both sides and three swords. ”

"Judging from the current signs, the Hui people are also eager to try and try to become opponents! This chaotic game of chess in the river will only be more difficult to play! Wang Fei had completely followed Wang Zhengjian's train of thought at the moment, and tried to express his thoughts.

Wang Zhengjian nodded approvingly and encouraged Wang Fei to continue.

"The expedition to Xiao Bolu and the siege of Tuqi Shi are all exquisite chess, but they cannot reverse the fundamental disadvantage of Datang." Wang Fei said carefully.

"What is the fundamental disadvantage?" Wang Zheng saw that the tiger's eyes were shining.

Wang Fei recalled the cycle of several losses and regains and gains in the Western Regions in history, and replied sonorously: "Hezhong is too far away from the heart of the Tang Dynasty, but Dashi, Tubo and Huifu are close and eyeing each other. ”

"It's not enough to just talk on paper and make judgments, Fei'er, let's talk about how to break the game." Wang Zhengjian was looking forward to it.

"The short-term strategy, following the example of Beiting and Anxi, opened the government and built the army. In the long run, immigrate to the real border and carry forward China. In his previous life, Wang Fei was well aware of the hardships and burdens of governing the Western Regions, and he also studied the gains and losses of governing the border in previous dynasties, and tried to think about the solution.

"How to attract immigrants? What is promoting China? Wang Zhengjian continued to ask about the school.

"The key to immigration is to lure them with profit. According to Judge Du, the trend of land annexation in the interior has become more and more intense, and the landless peasant households have fled in all directions and relied on the powerful and powerful, so that the government and military system cannot be maintained. Although the people of the mainland say that their homeland is difficult to leave, if they come out. According to Taiwan's decree, anyone who moves his family to the river will receive dozens or even hundreds of acres of land free of charge for each dingkou, and taxes will be reduced or exempted for the first three years. Wang Fei replied loudly, and his tone became more and more confident: "The first thing to govern the border is to win the people, and the people's aspirations seem to be chaotic, but in fact, there are traces. If we can vigorously promote the virtues of China in the river, fully promote the way of education, and use culture to transform the people of all directions, then. The will of the people can gradually become mine. ”

"Xiao Langjun's strategy coincides with what Du Hu thinks!" Du Huan smiled and praised: "Xiao Langjun, before the army started, Du Hu had ordered me to draft a chapter, if this expedition to the west went well, I suggested that the saint set up a new section in the river, supplemented by military tun and immigration strategies. ”

"It's just a precaution. But this intention is based on the victory of the Western Expedition. If the western expedition does not go well, it will be impossible to talk about it. Wang Zhengjian said lightly.

"Whether the Western Expedition can go smoothly or not does not depend entirely on our army." Du Huan said meaningfully.

"Liulang, although the victory or defeat is not determined by our army. But we must do our best and not slack off. Wang Zheng saw the right color.

"It's all about protecting the lesson!" Du Huan hurriedly replied: "I will do my best!" ”

"Fei'er, your insight is good." After explaining to Du Huan, Wang Zhengjian turned to Wang Fei and said: "But if a husband wants to make a difference, he can't just have knowledge, but also need to be down-to-earth, endure humiliation, and walk on foot." This process can be particularly arduous, and there are often pressures and temptations to give up. But as long as you think it's right, you must never give up on your pursuit! ”

Wang Fei nodded seriously, agreeing with his father's words.

"Easier said than done! Now you think you know and understand, but you don't really experience it, but it's still nothing. I hope you can still keep in mind the concept in your heart in the future! Wang Zhengjian said, with both expectation and some worry in his words......

After discussing the matter of returning to the border and governing the border, the army continued southward. The eagles and eagle slaves sent by the Hui were all assigned to the scout camp by Wang Zhengjian. The tame falcon can hunt all kinds of wild animals, which is very beneficial for scouts who often spy outside the barracks.

The fifty horses sent by the Hui people were very majestic, and Wang Zhengjian did not leave any of them, so he ordered all of them to be incorporated into the heavy cavalry to increase their combat strength.

Only the yellow fruit dismounted, because Prince Ye Hu pointed out that it was given to Wang Fei, and Wang Zheng saw that Wang Fei took it away.

After having Chi Yanhua, Wang Fei was reluctant to ride a low fruit to get off the horse, so he transferred the foal to Ayitengna. When he was in Tingzhou, he had long noticed that the Aitengna Riding Knight was not bad, but he had never had a suitable mount, so every time he traveled, he had to sit in the carriage all day.

"If I had been riding a horse instead of a car that day, things might have been very different! At least it won't be bloody......" Aitengna stroked the obedient fruit and dismounted, remembering the reunion with her brother again.

"Yiyue, you can give it a name." Wang Fei saw that Ayitengna's mood was a little low, so he had nothing to say.

"Well, the yellow horse is a hus, and this place is not far from Suye Shui. It's better to call it Su Yebi. Aitengna remembered her hometown and said in a low voice.

"Yiyue, don't be sad, you will definitely see Kudulu again!" Wang Fei comforted.

"Thank you, Xiaolang-kun." Aitengna said, holding back tears in her eyes. But what she thought to herself: "What if you see your brother?" What can I do? Where do we go from here? ”

On the second day of the fifth month, the 30,000 combined forces of the Beiting Army, the Shatuo Army, and the Huangjiasi Army arrived at Shattered Leaf City without hurry.

After arriving in Broken Leaf City, the Shatuo people were stationed in the pastures in the north of Suye Shui, and the soldiers and horses of Beiting were stationed on the plains in the south of Suye Water and the north of Broken Leaf City.

Six days later, the Hui prince Ye Hu and Dagan (the official position of the Hui general) led 10,000 cavalry to the Suye River Valley and chose to camp in the east of Broken Leaf City.

Around Broken Leaf City, the military camps are continuous, the people and horses are noisy, and the war is about to break out.

As for the discussion about the ambition of Hui and the importance of the river, Wang Fei kept it firmly in his heart and recorded it in his diary that day. At the same time, he also wrote down many ideas and plans for governing the frontier in his diary.

Decades later, when the Chinese civilization shone on the land in the river, Wang Fei accidentally turned out the diary of that year, found the immature handwriting he wrote back then, and burst into tears.

"Father, although this road is very hard, I haven't given up ......" Seeing the "bold words" written at that time, Wang Fei, whose heart was like a stone after experiencing a lot of rain, snow and frost, couldn't help but tremble.

At that time, Wang Zhengjian, who cared for him very much, was no longer by his side......

Hundreds of years later, Wang Fei's "Chronicles of the Western Expedition" was praised by historians, military scientists, and scholars as a brilliant masterpiece far beyond Caesar's "Gallic Wars". The school is divided into many branches, such as the Commentary School, the Suoyin School, the Commentary School, and the Fictional School, each of which insists on its own words and quarrels with each other.

At that time, the time-traveler had long since passed away, but the world he had changed and the achievements he had continued to do were still affecting everyone in the world......
