(Recommend the legend of brocade, the book of my friend Hu family's eldest young master, although the number of words is not much, but the writing is more fine, if you are interested, you can take a look!) )

The Xia army and the Tubo army combined also had more than 700,000 people, and compared with the determination of the Tubo to open up the land, the Xia State was largely under the idea of training, and of course, there was no lack of the meaning of leading the Tubo army to a decisive battle at a low altitude.

The news of the war between Tibet and the Xia army relieved many people of the Sui Empire, but just when the war between the two sides was in full swing, Yang Guang, the Yang Emperor of the Sui Dynasty, finally decided to go north to recover the land south of the Great Wall in one fell swoop.

Yang Guang had long been preparing to arrange for the army to go north, but his degree of secrecy about the Sui army was still very good, not only when the army went north, they marched at night and hid during the day, but even set up roadblocks in various places under the pretext of guarding against Xia Guo's meticulous work, preventing Xia Guo from getting news soon.

In the autumn of the forty-sixth year of the Xia calendar, Yu Zhongwen and Wang Rengong respectively led a large army to cross the border into the territory of the Xia State, and behind them there was a second group of more than 300,000 troops organized by Yang Guang, which was mainly used to support Yu Zhongwen.

At this time, Yang Guang's eastern capital only retained 100,000 troops, which can be said to have taken out all the power in his hands, in order not to be murdered by the Guanlong Xianbei military aristocratic group, Yang Guang even sent his own trusted general Xue Ju to lead 20,000 elite soldiers to Hongnong County, firmly controlling the two checkpoints of Tongguan and Hangu Pass.

In addition, Yang Guang also defended Hedong County with Xue Shixiong, defended Xingyang County with the general Wei Meng, and defended the eastern capital Luoyang with the leader of the forbidden army, Yu Wenhua, and other counties of the Sui Empire were guarded by the trusted generals of Emperor Yang of Sui, which can be said to protect himself safely and steadily.

Yang Guang is very confident on the surface, but in fact, he is very inferior in his heart, especially after the defeat of the Liaodong War, it has brought him an infinite shadow, even if he has more than one million Sui troops again, but he still feels uneasy in his heart, after all, the Sui army was still defeated by nearly two million people in the Liaodong battlefield alone.

If you count all the forces mobilized by the Sui army and the Turks mobilized by the entire Sui Empire at that time, then the entire army of the Sui Empire reached almost three million people, so Yang Guang's current army was still too far behind.

After the defeat of the Sui Empire, the people of the Sui Empire, who were mainly self-cultivated farmers, suffered heavy losses, and now that the land annexation within the Sui Empire is developing rapidly, where are the people willing to join the army?

The people of Guanzhong were the main force in the war last time, and at this time, the young and strong people in the entire Guanzhong lost too much, the yeoman farmers in Guandong were unwilling to join the army, the military nobles of Guanlong Xianbei were unwilling to support, and the Guandong Shi clan would definitely not be able to take out all their servants to fill the big hole of the Sui army.

Therefore, in the next few months, the Sui army only recruited less than 100,000 young men, far from the scale of one million people required by Yang Guang.

In order to complete Yang Guang's task, officials from all over the country led troops to forcibly recruit young and strong, and a large number of people in the Sui Empire who were unwilling to join the army had to be forcibly brought to the army to become soldiers of the army.

However, there are also a large number of people who are unwilling to sell their lives have fled to the mountains and forests, which has made the bandits from all walks of life who were already very powerful before further development, and the bandits in some places in Taihang Mountain even have tens of thousands of people, although they are full of old and weak women and children, but they are already very terrifying.

Yu Zhongwen and Wang Rengong's good news kept coming, and the Sui army suddenly went north to find that Boling County and Lou Fu County in the north were actually empty, whether it was the countryside or the city, it seemed that they had been abandoned by the Xia army, and the Sui army actually captured these two places without much effort.

The morale of the soldiers of the Sui army was immediately boosted, but Yu Zhongwen, Wang Rengong and Yang Guang were not in a good mood, because they knew that Xia Guo must have discovered his plan a long time ago, otherwise how could they withdraw all the people and troops in advance, if this is the case, it is likely that this military operation will have an unfavorable situation.

Really!

When Wang Rengong led 200,000 Sui troops to Yanmen County, suddenly 200,000 Xia troops appeared opposite the Sui army, and what surprised them even more was that they didn't know when another 100,000 Xia troops appeared from behind the Sui army, cutting off their retreat.

It can be said that even if Wang Rengong, a general with a strong military strategy, firmly guards his camp, he will reappear in the defeat of Liaodong within a month due to food shortage.

Wang Rengong is indeed a famous general, with 200,000 Sui troops and the Xia army to fight without a victory, that is, under the desperate resistance of the Xia army, they can't break out of the encirclement, and the number of the Xia army continues to increase as time goes by, and what makes them even more depressed is that the Xia army still comes to fight with them with a wheel.

More than a dozen messengers desperately broke through the siege, and in the end only two groups succeeded in delivering the letter to Luoyang, Yang Guangguang was taken aback, and immediately urgently ordered Shi Wansui, who was resisting the Xia army in Henan in the upper county of the Great Wall in Guanzhong, and urgently ordered him to quickly cross the Yellow River to the east to rescue Wang Rengong's army.

However, at this moment, Shi Wansui sent an urgent report, the 200,000 Xia troops who were originally stationed in Shuofang suddenly went south to Koubian at this time, and there was actually a posture to take Guanzhong, and Yang Yichen was stationed in Jincheng County at this time to guard against the threat of the Xia army and Tubo and could not leave at all.

Yang Guang's anxious regiment turned, Yu Zhongwen had also fought with the Xia army in Shanggu County at this time, Yu Zhongwen, who had learned the previous lesson, took the camp step by step this time, after meeting the 300,000 troops supported by Yang Guang, Yu Zhongwen already had 600,000 troops in his hands to protect himself, but he was unable to rescue Wang Rengong.

Thinking about it, Yang Guang never dared to trust the Guanlong Xianbei military aristocratic group, after all, it had been very unpleasant between himself and the Guanlong Xianbei military group in recent years, but soon he thought of an excellent candidate, that is, his cousin Li Yuan.

Li Yuan advised Yang Jian not to ignore the threat of Tubo at the same time as Yang Jian's all-out attack on the Xia State, for which he also specially requested to go to Longyou to serve, and successively served as the county guard of Hanyang County, Tianshui County, Longxi County and other places, and was very well received by the local people during his tenure.

Although Li Yuan is currently only the Taishou of Longxi County, after losing the four counties of Tuyuhun such as Xiping County, Lintao County and Jincheng County are the first line of defense of the Sui Empire to the outside world, while the wealthy Longxi County is the most favorable backup for Lintao County and Jincheng County.

If Jincheng County and Lintao County do not have too much arable land, the grain is simply not enough to feed the local hundreds of thousands of Sui troops, if there is no food and materials from Longxi County, Lintao and Jincheng will not become the most stable front line, in addition, Longxi is also a springboard for attacking Guanzhong, so the strategic location of Longxi County is very important.

Li Yuan, as the grandson of Li Hu, one of the Eight Pillars of the Western Wei Dynasty and the Northern Zhou Dynasty, had a close relationship with the Guanlong Xianbei military aristocracy, and Li Yuan's mother was the sister of Yang Guang's mother Dugu, so Yang Jian and Yang Guang trusted this ability, outstanding appearance, and kind relatives.

After Yang Guang appointed Li Yuan as the deputy commander of the Hedong march, he recruited government soldiers and young men from the land of Guanzhong again, plus a part of the Sui army stationed in Chang'an, Guanzhong, to form an army of 150,000 people, and quickly marched north from Fenglingdu to support Wang Rengong.

Xia Guo seems to have known every order of Yang Guang for a long time, just when Li Yuan had just crossed the Yellow River and headed north, the Xia army launched a fierce attack on Wang Rengong's troops in the encirclement, and when Li Yuan led his army to reach Taiyuan County in a hurry, Wang Rengong's headquarters had been completely destroyed.

So Li Yuan justifiably became the commander of the Hedong march army and took over the defense of Taiyuan County, and the Xia army did not continue to attack Taiyuan County in the south, so both Sui and Xia focused their main efforts on Shanggu County, where Yu Zhongwen was already in a full-scale battle with the Xia army.

Because the Xia State gradually recovered a large number of troops after the end of the Liaodong War, and the Xia army that fought against the Sui army in the area of Zhuo County and Shanggu County was only 500,000 people, so the war between the two sides did not progress quickly.

Of course, this also has something to do with Xia Guo's use of Sui Jun as a sparring partner to a large extent.

Xia has now become the most powerful empire in the world, and there has been no major war in the five years since Wang Ze became emperor, which is very bad for the Xia army, after all, the army can only grow into a real army in iron and fire.

It seems that the Xia Army is still prestigious, and no enemy dares to fight against the Xia Army, but that is because the Xia Army still has a large number of veterans and grassroots officers who have been killed step by step in decades of continuous battles, and they are the real backbone of the Xia Army.

With the retirement of veterans in the future, a large number of recruits who have not experienced the war continue to enter the army, even if the Xia State has not relaxed the training of the army at all, but after a long time without war, the combat effectiveness of the army will inevitably decline, and only through continuous war can the combat effectiveness of the army be guaranteed to remain strong.

This is also one of the reasons why Xia Guo is reluctant to defeat the Sui army quickly, after all, such a good sparring partner is still too difficult to find, even if the Tubo people can fight with Xia Jun in Xiping County and Hexi Corridor, it is also because Xia Guo has the idea of sparring partners.

In addition, there is another reason, that is, the Xia Kingdom hopes to continue to consume the vitality of Tibet in the low-altitude areas, after all, Tibet is a sparsely populated country, and according to intelligence, the population of the entire Tibet will definitely not exceed two million.

This is still after calculating the entire population of Tubo after its annexation of Tuyuhun, which means that Tubo has a maximum of 500,000 young and strong men, so if one of Tubo's young and strong men consumes, his strength will be reduced by one point.

In fact, Tubo Zanpu Nangri Zanzan's plan could also guess Xia Guo's plan, but he didn't have any way, after all, the Tubo people had just become strong, and the accumulated heritage was not enough.

The Tubo people are now poor and white, and they have nothing but a bad life, so even if he watches the heroic Tubo warriors die on the battlefield, he can only insist on fighting against the Xia people, and he is blocked that the Xia army cannot fight on the plateau for a long time.

In addition to insisting on fighting the Xia army, Nangri Ronzan also had the idea of making peace with the Sui Empire, which had the financial resources and powerful technology that made him salivate.

If you can take the opportunity to make peace with the Sui Empire to obtain a large number of craftsmen and military technology, then Tubo's national strength will get a great jump, and it is not a problem to help Xia Guo contain his Yangtong, Zhangxiong, and Dongqiang women at present.

In the original history, before his death, he regretfully said to Songtsen Gampo that the thing he looked forward to the most was to make peace with China, so that Tibet could become the most powerful empire.

The facts also proved the analysis of Nangri on praise, although the Tibetan people before Songtsen Gampo married Princess Wencheng could threaten the Tang Dynasty, it was only one of the many countries on the plateau.

After marrying Princess Wencheng and gaining a large number of craftsman skills, Tubo not only quickly conquered other countries on the plateau, but also became a superpower capable of defeating the Tang Dynasty.

Soon, Nangri Lunzan sent an envoy again to ask Emperor Yang Guang of Sui to marry the princess.
