Zhao Yu judged that Yuxi Timur must invade the south, not just based on intuition, not to say that he had been planning for a long time, and even did not hesitate to drive Yangzhou to lay a trap. He had done so much, in fact, he still couldn't completely conclude in his heart that he would be in the plan, but a few days ago, he received a piece of information from the bureau that he decided that his plan was successful, and Yuxi Timur finally got into his trap.

The information collected by the bureau will be divided into several levels according to its importance, and the scope of circulation will be demarcated according to this, which is done out of the need for secrecy, because Zhao knows that he can place spies on his opponent's side, and the opponent is also likely to place spies on his side; The second is out of the protection of spies, after all, there are some contents that allow people with intentions to deduce the source of information from them, and find out the initiator accordingly.

What Zhao Yu obtained was a top-secret piece of information, the content of which was the conversation of Yuxi Timur at a military conference convened by Gaoyou, but this information did not completely record every word he said, and did not even explain his troop deployment at the meeting. This shows that the spy has a low status in the Mongolian army, and is not qualified to participate in such high-level meetings, and is probably only a low-level servant, or a soldier on duty outside the tent, so he cannot stay in the tent all the time, and what he hears is only a few words, which is incomplete.

However, a few words about the 'national capital' of Yuxi Timur were recorded, and it was through these few sentences that Zhao Yu deduced his judgment that he would definitely cross the Yangtze River and invade the south, and regarded him as a powerful opponent at present. Because his vision at the strategic level has gone beyond the category of a military general, and even beyond those in high positions in the court, he can see the potential crisis that is enough to destroy a country, and hopes to eliminate the hidden danger through his own plan.

For the knowledge of Yuxi Timur, Zhao Hao couldn't help but raise his vigilance, the current people may not understand the deep meaning, but he is very clear as a later generation. As far as the current Xinjiang region is concerned, the Yuan court still has not fully occupied it, and there are still many areas controlled by the Haidu forces, but although it has united many forces to try to fully control this region, it is difficult to succeed, and it is defeated under Kublai Khan's policy of tuntian.

Haidu can be said to be the most stubborn enemy of Kublai Khan's life. In order to maintain its own defense line, it specially sent more than 20,000 people to garrison the tuntian team in Xinjiang and reclaimed more than one million acres of land, which also enabled the Yuan court to control the underground strength of Xinjiang, so the success of the tuntian even determined the success or failure of Kublai Khan's foreign war, and in the end the Yuan court had no choice but to retreat in Xinjiang, and the Haidu changed tactics and sabotaged its policy in Xinjiang Tuntian, resulting in the loss of land.

The strategy of planting grain in the tuntian fields and then obtaining military rations in the tuntian fields to achieve the goal of holding the border defense is not the exclusive domain of the Han people, and there are precedents to follow. During the Tang Dynasty, the Tibetan tribes that arose in the Lhasa River Valley originated from the farming tribes of the Lhasa River Valley, who were the first to discover and cultivate barley. The history of the unification of Tibet is also the history of the continuous annexation and integration of other surrounding tribes by the Tubo people who worked in agriculture. In addition, there were few Turkic "Great Khans" in Tibet, and the Tibetan customs and culture were generally accepted in the areas conquered by the Tibetans.

In addition, after the fall of the Yuan Dynasty, the cities built on the grasslands in the past were increasingly deserted due to the lack of food supplies from the interior, leaving only a decadent scene for future generations to mourn. The Mongols did not write poems about the sorrow of the ruins, but used their actions to recreate the glory of their ancestors, and Altan Khan was one of them.

Altan Khan launched many military campaigns against the Ming Dynasty during the Jiajing period, and even once came to the city of Beijing, trying to restore the former glory of the grassland. He also established a number of cities on the grasslands, the largest of which is now Hohhot. In order to build these cities, Altan Khan used great manpower and material resources, including some Han Chinese who were captured by his open and secret tricks. In terms of military ability, Altan Khan was not inferior to Nurhachi, nor inferior to his ancestor Kublai Khan, and he even formed a musket unit, but in the end he failed to reproduce the glory of his ancestors.

The success or failure of these heroes is that some people realize it, or they don't realize it: with grain that can be stored, the nomads have the material basis for a long-term confrontation with the Central Plains Dynasty. Apparently Yuxi Timur was aware of this, and although he did not yet know where Genjie was, he had realized the important role of food for a country, and realized that the current economic chaos in the country was due to problems in the steppe centered on the Horin forest.

After Kublai Khan seized the Central Plains, he moved the ruling center to Dadu, but Helin is the place of Mongolia and is still the political center of the country, and the Mongolian steppe often has snow disasters and droughts during the Yuan Dynasty. And as an important part of the political system of the Yuan court, the main princes of the Kuritai Assembly also stayed in the grassland, in order to stabilize these princes and nobles, the establishment of the 'gift system', there are many kinds of gifts, such as ascending to the pole, pro-government, longevity, emblem, enjoyment, promotion, canonization, military merits, weddings and funerals, etc. But in either case, it was to give these royal nobles, and a large number of servants were rewarded with gold and silver, which increased the financial burden of the state.

Similarly, maintaining a post station from Horin to the khanates and the Central Plains for the sake of the steppes was costly and cumbersome, as were the salaries of the officials who managed the steppes and the post stations. Therefore, in order to maintain the stability of the hinterland, the wealth that the imperial court conveys to Helin every year accounts for a large part of the national tax revenue. The current chaos is precisely because the imperial court lost the rich Jiangnan region, which led to a great reduction in taxes, and it is unable to bear this heavy burden, and the only way to solve this problem is to retake Jiangnan......

"Since they are going to cross the river, we must also cooperate well!" Tan Fei's judgment coincided with his own, and he smiled.

"Your Majesty's intention is to delay the attack on Yangzhou?" Tan Fei asked.

"No, we will rush to attack Yangzhou City, but we will ......" Zhao Yu smiled and pouted.

"Your Majesty's intention is to attack but not break, but to make a statement that you are determined to win!" Tan Fei understood what the little emperor meant after thinking about it for a while, and said softly.

"It is precisely in this way that the doubts of Yuxi Timur can be completely dispelled, so that he can cross the river with confidence." Zhao Yu nodded.

"Your Majesty, Yuxi Timur has concentrated the troops of the two Duwanhu Prefectures this time, about 100,000 people. However, the forces set up by our ambush seem to be slightly insufficient, and these people will break into the south of the Yangtze River, and once they break through the encirclement, they will inevitably cause turmoil. Tan Fei frowned.

"Well, that's exactly what you're talking about. I didn't expect Yuxi Timur to be so resolute, regardless of the danger of losing the two Huai, he used all his elite soldiers for the southern invasion! Zhao Yu previously estimated that under the posture of his army crossing north and approaching the city, Yuxi Timur would adopt the strategy of encircling Wei to save Zhao and send troops to the south to threaten Lin'an in order to force himself to retreat. At present, its action is no longer to relieve the siege of Yangzhou, but to take advantage of the emptiness of his rear to copy his own nest, you must know that the troops used by Boyan to destroy the Song Dynasty were only more than 200,000.

"Your Majesty, for the sake of safety, my subordinates think that since our goal of luring the enemy has been achieved, it is better to make a surprise attack with all our strength when the enemy is preparing to cross south, and annihilate the enemy in Bandu. There is no need to wait for the enemy to penetrate deep into the south of the Yangtze River and then ambush and encircle and annihilate him. Tan Fei said.

"With your strategy, it is safe, although you cannot achieve the strategic goal of capturing Yangzhou, you can also complete the strategic goal of destroying most of the enemy's living forces." Zhao Hao pondered for a moment, touched his chin and said thoughtfully, "But if we withdraw our troops and attack the enemy in Nandu instead, how to transfer, how to receive the enemy, how to break the back, there are many difficulties, and we even face the danger of being attacked by the enemy in the field." ”

"The subordinates are just talking nonsense, everything still needs to be decided by His Majesty!" Tan Fei knew that the little emperor's worries were not unreasonable, if he wanted to quietly leave the land of Yangzhou, and quietly rushed to another battlefield, and he had to march long distances in the enemy's territory, it was almost impossible not to be discovered by the enemy. At the same time, it is very likely that they will be attacked by enemy cavalry during the march, and at that time there will be no camp to rely on, and there will be no terrain to use, and if you have to engage the enemy in a field state, defeat will be a disaster, so you do not want to interfere with Your Majesty's train of thought.

"What is the situation in Yangzhou now? They have suffered such a great defeat, and I am afraid that they will not dare to fight us again! Zhao Yu understood that the adjustment of the battle plan should take into account all aspects, although the war was urgent, it could not be rushed, and many things still needed to be discussed with the generals, so he temporarily gave up asking questions.

"The enemy army was defeated, and Chen Dutong took advantage of the chaos to seize the old site of Baoyou City, completely cutting off the connection with the north, they can only rely on the city for the time being, where do they dare to fight!" Tan Fei said with a smile, "According to the report of the spies in the city, Badu said that he was sick after the defeat, and handed over the military and political affairs in the city to Ma Shao, the right minister of the province. ”

"Oh, it's a bit unexpected that the king of Zhennan in the city didn't take the opportunity to take over the military power and preside over the defense of the city!" As early as before the outbreak of the war, not only did the Affairs Bureau send spies, but also the Military Intelligence Department of the Privy Council and the Jiyi Division of the Military Department, and even the various ministries involved in the war sent spies to sneak into the city to find out the news, so the sources of information are multifaceted, but no matter which one obtains the information, it will be summarized to the Imperial Front Office, so that Zhao Yu can understand the situation in time. He suddenly remembered that his old enemy Huan Jie was also in Yangzhou, and he should be the highest knighthood in the city at the moment, but he did not preside over the war, which made him feel surprised.

"Hehe, I'm afraid that Huan Du will avoid His Majesty, how dare he fight against His Majesty!" Tan Fei listened and looked at the little emperor, and said with a dumb smile. He knew that as early as Qiongzhou, the biggest enemy facing the Xing Dynasty at that time was the army under the command of Zhennan Wang Tuhuan, but several major battles were defeated, not to mention the disgrace, and he also lost the favor of Kublai Khan.

"This is in response to the sentence that enemies don't get together, if you can capture him alive this time, it will also set a precedent for my dynasty!" Zhao Hao also laughed.

In Zhao Hao's eyes, the two are really a pair of enemies, and after he inherited the throne, Tuhuan was also named the king of Zhennan, and presided over the military and political affairs of Jiangnan with the assistance of Ali Hague. However, several attacks on Qiong failed, and the losses were heavy. And the order to conquer Annam was put on his own behalf, which indirectly led to the death of Instigating Du and Li Heng, which angered Kublai Khan and was punished by not being seen for life.

Fortunately, Kublai Khan died soon after, and in order to gain the support of the Jiangnan forces, Zhenjin wantonly wooed and gave him many privileges and promises. But when he returned from the funeral, he found that Jiangnan had changed hands, and he had nowhere to go. And there is no use value, the earlier promise is gone, fortunately, the real gold has not been wiped out, and it was sent to Yangzhou to preside over the two Huai military and be responsible for the salt tax.

Although Huan Tu was allowed to preside over the two Huai military, his power was greatly weakened, and he could not fully control the right to transfer troops as before, and only exercised the right to supervise the Yuan army in Jianghuai and other places, and only the five hundred cowardly Xue army subordinate to the palace could be mobilized, so in fact he was only the commander of the Jianghuai army in name, and in fact the control of the army was still in the Privy Council of the Imperial Court and the Duwanhu Mansion.

However, real gold has not been disadvantaged, and everyone knows that as long as it is stained with salt, the official position is fat. Because Yangzhou is close to the sea and the river, and has the convenience of canals, it has always been the distribution center for salt transportation from the south to the north. After the loss of the salt works in the south of the Yangtze River, Yangzhou's position became more prominent, and most of the sea salt produced by the surrounding salt factories was transported from Yangzhou to various places. With the power to manage the salt industry, Tuhuan naturally would not let go of the opportunity, and soon gathered a huge amount of wealth, if it weren't for the Song Army's small days of besieging the city in Beidu!

"Your Majesty, I'm afraid it's the treasury of the Zhennan Palace!" Seeing the little emperor's obscene smile, Tan Fei realized that His Majesty was not very interested in whether he could capture the defeated general of his subordinates, but was worried about the countless gold and silver treasures in the Zhennan Palace, and couldn't help but quip.

"Hehe, I just don't know which one is richer in his family or the thief, I haven't raided the prince's house yet!" In front of his own people, Zhao Yu did not hide his 'greed for money' nature, with a smile on his face, and he almost said with a slapstick on the corner of his mouth.

"Your Majesty rest assured, as long as Yangzhou City is conquered, your subordinates will definitely seize the palace first, and let Your Majesty go to check it." Tan Fei also really promised with a salute.

"Huh!" Zhao Yu laughed dryly twice, and turned to the topic again, "Ma Shao is a Confucian scholar, and he has no experience in the army, so he is afraid that he will be in charge of military affairs, and he is only afraid that he will be in charge. ”

"Your Majesty, it is reported that it doesn't look like he's pretending to be sick, saying that he has 'nail removal wind', and he is very sick and is already bedridden!" Tan Fei shook his head and said.

"Removing the armor, there is really this disease in the world, I just think it is a legend!" Zhao Yu was stunned when he heard it. In his previous life, he listened to the commentary, and he often heard this word, but no one could tell what kind of disease it was, so he only thought that the commentator made it up.

"Your Majesty, armor removal is a common disease in the army, but it is rare in our army, and Your Majesty may not have heard of it......" Tan Fei was also surprised, His Majesty is known as the 'divine doctor', why didn't he know about this disease, so he explained.
