(Thanks to ar, Zhuo Wei, and Thirteen Friends for their support, thank you!) In the early morning sunlight, above the Kaiyuan Hall of Zihui Palace in Luoyang, hundreds of civil and military officials shouted long live and congratulated each other. Yi Feng smiled and said, "All the ministers are safe." "If the officials have something to do, they will report, but if there is nothing to do, they will leave the court!" Pei Shiju, the minister of Huangmen, stepped forward and raised his wat to report: "Marshal Gao Jia, the deputy envoy to the Privy Council, led the Western Expeditionary Army. The coalition forces of Datou and Tuyuhun were defeated in Hexi. Datou was defeated and fled to the Western Regions. Murong Fuyun's country was destroyed and captured. Now the countries in the Western Regions are shaken. Gaochang and other countries have sent envoys to pay tribute and worship. Datou Khan and Dulan Khan They all sent envoys to request submission and ceased fighting. Now that the envoys from all parties have arrived in the capital, I don¡¯t know what your Majesty wants to do. " Tuyuhun was originally a branch of the Murong tribe of Xianbei. It has been located in the capital since the Western Jin Dynasty. The country was founded in the Qilian Mountains and the upper reaches of the Yellow River valley. In the Sui Dynasty, its nomadic range ranged from Xiping to the west of Linqiang City, to the east of Qiemo, to the south of Qilian, and to the north of the Snow Mountains. It was four thousand miles from east to west and two thousand miles from north to south, with the capital Fuqi City Forty-five miles west of Qinghai, as a country occupying thousands of miles of land, Tuyuhun is remote and mainly nomadic, but its population is not small. The largest mobilization of troops in the country reaches 80,000. According to Hu Almost all the people of the tribe are soldiers, and the total population of Tuyuhun exceeds 300,000. In order to stabilize the northwest region, the Sui Dynasty used all its strength to fight against the Turks. In the eleventh year of the founding of the Emperor, the daughter of the clan was granted the title of Guanghua Guangzhu and married to Tuyuhun Khan Murong Shifu. Later, Murong Shifu was killed by his brother, and Murong Fu Yun succeeded him. Khan, still married Princess Guanghua. It can be said that during the period of Emperor Gaozu, the relationship between Tuyuhun and the Sui Dynasty was pretty good through marriage. There are not many major conflicts between the two sides. But when Yang Xiu killed Emperor Gaozu and usurped the throne, in order to win over the Tibetan troops and borrow troops, he promised Tuyuhun many conditions, including treating the clan daughter as a princess and marrying Tuyuhun, and rewarding Tuyuhun with the Hehuang area that Tuyuhun had always longed for but could not get. The Hehuang area is the valley between Huangshui and the Yellow River to the west of Qinghai Lake. In a narrower sense, it specifically refers to the Huangshui River Valley. Although this area is not large, it is one of the few fertile areas in the Qinghai Lake area that is suitable for farming. Although Tuyuhun occupies an area of ??several thousand miles, most of it is very barren, which is why they only have a population of more than 300,000. If they can get the Hehuang area. If they develop over time, it won't be a problem for their population to exceed one million. Then Liu Xiu was defeated and committed suicide soon, and Yi Feng Shouchen proclaimed himself emperor, and naturally completely vetoed the previous transactions. Murong Fuyun found it extremely difficult to accept the loss and recovery of the Hehuang area. In order to preserve this fertile land. He finally joined forces with Datou and took advantage of the war between the Sui Dynasty and Goguryeo to invade Dunhuang. Originally, they did not really want to attack the Sui Dynasty, but they wanted to express their attitude. They wanted to blackmail the Sui Dynasty militarily, force the Sui Dynasty to negotiate peace with them, and maintain the division of power before the Northern Expedition. It's just that they mispredicted the situation. Yi Feng was simply not the kind of person who could be blackmailed. Or rather. Yi Feng was very clear about the entire situation and knew the strength of the enemy and ourselves very clearly, so he had long seen through that they were just bluffing and wanted to blackmail. To this. Yi Feng sent out an army for the Western Expedition. As expected, the two sides fought in Hexi. In this battle, although the combined forces of Tuyuhun and the Turks numbered more than 200,000, they were no longer as elite as they were before the Northern Expedition. After the Northern Expedition, Datou's strength was greatly reduced. The more than 100,000 troops who were barely scraped together were no longer elite. The fifty thousand soldiers and horses assembled by Tuyuhun could not change the final situation. The Western Expeditionary Army led by Gao Jia fought steadily in Hexi. This battle lasted for more than half a year. Finally, after the Sui army won the Battle of Liaodong, Yi Feng once again increased his troops in Hexi. With the arrival of new troops, Gao Jia seized many opportunities. They attacked on the way, first divided their troops to attack the territory of Tuyuhun, forcing Tuyuhun's army to return, and then intercepted it halfway, defeated the Tuyuhun army first, and then faced Datou. Datou was defeated by Dunhuang again and retreated to the Western Regions. Gao Jia took advantage of the situation and turned around and charged into Tuyuhun. After a rapid sweep, the royal city of Tuyuhun was breached, the Khan was captured alive, and the Tuyuhun kingdom was destroyed. The demise of Tuyuhun, which had been a country for nearly three hundred years during the Sui Dynasty, caused shock throughout the Western Regions. Among them, the most frightened one was Du Lan Yu Da Tou. In the Northern Expedition of Sui Dynasty, the Turks were severely defeated, but their vitality was only severely damaged, and they still had some strength. But immediately after the Sui Dynasty defeated Goguryeo in the east, Tuyuhun in the west, and defeated the Turks again, both Datou and Dulan felt that a disaster was coming. No one can contain the disruptive Sui Dynasty anymore. After quelling the civil strife and defeating Goguryeo and Tuyuhun, the next target for the Sui Dynasty must be the Turks. The countries in the Western Regions, such as Gaochang and Yiwu, which were originally dependent on the Turks, sent envoys to the Central Plains to pay tribute to the Sui Emperor. Even Dulan and Datou finally lowered their proud heads and sent out the mission. In addition to sending envoys, Datou and Dulan also sent their sons as hostages, and even sent their granddaughters and daughters to the Sui Dynasty with the delegation, hoping to avoid this disaster through marriage. Yi Feng said: "During the Kaihuang period, Emperor Gaozu attached great importance to the harmony with Tuyuhun, so he specially asked Lord Guanghuaguang to enter Tuyuhun and marry him. Then Murong Fuyun, the younger brother of Tuyuhun Khan, launched a rebellion and killed his brother to seize his throne. After taking the throne of Khan, he later colluded with Yang Xiu, and did not think about the Central Plains' reflection on Tuyuhun's benevolence for many years and his desire to seize our territory. After I succeeded to the throne, I remembered his first offense and ignored his faults. However, he thought I was weak. While we were at war with Goguryeo in the Sui Dynasty, we united with the Turks to invade Hexi again. Now that Fu Yun has been defeated and the country is destroyed, but the leader is trying to escape the disaster by relying on one more woman. How can it be so easy in the world? ? It is my intention not to allow the Turks to surrender." There was silence in the palace. Yi Feng continued, "Tuyuhun has been destroyed. I intend to take this opportunity to send troops to the north again to capture Datou and Dulan alive." The ministers were secretly frightened by the emperor's ambition. In just two years, the imperial court successively carried out the first eastward expedition to Goguryeo, then a large-scale northern expedition, then to quell the civil strife, then a second eastward expedition to Liaodong, then a westward expedition, and then sent troops to annihilate Tuyuhun, now that the Turks have surrendered, the emperor still refuses to agree and wants to launch a second Northern Expedition. In two years, this kind of war involving hundreds of thousands of people has been fought five times. It can be said that it has reached its limit. Yang Su came out and said, "Your Majesty, in the past two years, the imperial court has been on campaign. The soldiers have been fighting in all directions. They are fighting endlessly and are exhausted. It is also very difficult for the imperial court to supply food, grass and equipment. Now that Goguryeo, Turks, Western Regions, etc. have asked to surrender, do you agree temporarily? , let the soldiers and the people rest for a while, and then discuss it again?" Yi Feng looked at Su Wei, "What do you think, right servant?" Although Su Wei knew that the emperor wanted to fight, as a left servant, He also knew the situation of the imperial court very well. There would be another Northern Expedition, which would require mobilizing countless soldiers, horses and food. At that time, their Shangshu Province would be the most strenuous. Therefore, after hesitating again and again, he said truthfully, "The reason for the Northern Expedition was that the Turks had regained their strength after years of recuperation, especially Datou. Although they were located in a corner of the Western Region, they defeated Persia and stabilized the Western Region. Then they defeated the capital Lan and became a leader in one fell swoop. The Turks have been united for more than ten years, and Qidatou is very ambitious. If he does not take the initiative to attack the Northern Expedition while his rule over the Turks is not stable, it will be a big trouble in the future. However, the current situation is different from the original after all. In the Northern Expedition, the Turks had been severely defeated, their vitality was severely damaged, and most of them had surrendered. After the previous battle in Hexi, they were defeated again. Now the Turks were no longer a serious concern of the imperial court, so they could postpone sending troops. After all, the imperial court had used troops for many years. Not only are the soldiers and the people tired, but the government's finances have also been exhausted. This is also a very dangerous matter. It is necessary to recuperate the people's strength and wait for the lack of energy to recover before considering the Northern Expedition. " Both servants clearly opposed another Northern Expedition for the same reason. They are all similar. The troops are used too frequently, the government's finances are consumed too much, and the people are tired. After all, among the millions of troops of the imperial court, there are still hundreds of thousands of soldiers. These people are usually farmers, but they have to be drafted to the front line during war. Although they do not need to be paid military pay, they must also be given subsidies. More importantly, it will inevitably affect When it comes to family production with hundreds of thousands of soldiers, there is a lack of labor, and the family's farming will definitely be greatly affected. At the same time, hundreds of thousands of troops were mobilized to fight, and military salary, allowances, rewards and pensions were all huge figures, not to mention that every battle required multiple civilians to transport logistical supplies. In addition, the consumption of war was also huge, including food, grass, ordnance, as well as war horses and draft horses. In the Liaodong War, although the number of casualties was not large, the number of war horses and draft horses lost was hundreds of thousands. Of course, the imperial court now took over Liaodong, conquered Tuyuhun, and successively established three provinces: Liaodong, North Liaoning, and Qinghai. In addition to the previous three provinces of Liaoxi, Great Wall, and North Great Wall, the immigration and land reclamation plan in these six provinces cost countless money and food, and It is difficult to see results from these massive investments in the short term. The imperial court has a three-year tax-free tax policy for these six provinces to encourage people to immigrate. This also means that there will be no return on investment for at least three years. The imperial court's annual income is basically fixed. Fighting a war involving more than 100,000 people sometimes consumes several years of national reserves. With successive major battles, coupled with the immigration development of newly established provinces, the imperial court continues to invest. If you add in the several big projects that have arisen in the Central Plains, the capital construction plan, and the canal development plan, the money has really been sucked away like running water. The imperial court now has a deficit of more than 30 million. , 20 million bank loans and 10 million bonds, but this money has all been withdrawn. The meritorious rewards of the officers and soldiers of the Western Expedition have not yet been assessed. Once assessed, this will be a huge expenditure. Not to mention the Northern Expedition again, which will cost countless money and food. Where will the money come from? The imperial court had previously reset the titles, cleared out the titles, and recovered a lot of land, but compared with these expenses, it was just water. In short, the attitudes of the two servants, Yang Su and Su Wei, were very clear. Although financial problems were not the biggest obstacle to the Northern Expedition, they were indeed an avoidance issue.Difficulty opening. Unless the emperor can come up with another 20 to 30 million yuan, it would be better not to talk about another Northern Expedition. (To be continued)
