After capturing Xingtang Mansion, the Wu army did not stop there, but took advantage of the great victory to continue to attack north.

In the next three months, the Wu army was like a bamboo, successively capturing the three major feudal towns of Henghai, Zhenzhou and Dingzhou, and Fu Xi, Ren Yuan, and Wang Du surrendered to Wu one after another.

However, in these three months of war, the Wu army also suffered great losses, and the soldiers were tired, and at this time winter had arrived, and the Wu army, which was mainly southerners, felt uncomfortable with the cold winter in the north, so the offensive of the Wu army was temporarily stopped.

Li Cunqiao's eldest son, Li Jiqi, the king of Wei, took this opportunity to ascend the throne in Taiyuan with the support of Meng Zhixiang and others, and established the Northern Tang Dynasty.

It's a pity that the people's hearts are in turmoil at this time, and the territory that the Northern Tang Dynasty can control is only the ten states around Taiyuan, and its strength cannot be compared with the previous Later Tang Dynasty.

In February of the following year, after the cold winter had passed, spring came again.

The Wu army attacked north again, and the target was Shi Jingjiao, the envoy of Lulong Jiedu, who was entrenched in Youzhou.

In the face of the large-scale attack of the Wu army, Shi Jingjiao knew that it was difficult to resist with his own strength, so he sent people to ask the Khitans for help and called him a tribute.

At this time, the competition between the Khitan, Yelu Bei and Yelu Deguang was already in a critical period, and he did not want to cause side effects, but Shulu, who actually controlled the power of the Khitan, realized that if Wu was allowed to seize Youzhou and complete the unification, then the Khitan life would not be easy in the future.

Therefore, after the law, he overrode public opinion and sent 30,000 elite horsemen into Youzhou to rescue.

When the Khitan cavalry arrived in Youzhou, the Wu army had been storming under Youzhou for more than a month, the soldiers were already tired, and the enemy reinforcements arrived, in order to prevent accidents, Li Chengding, the commander of the Wu army, ordered to retreat.

Yang Wu was not dissatisfied with Li Chengding's order.

He is not Song Taizong, and he will not do anything about remote command in Luoyang, he has always only controlled the overall situation of the war in front, and entrusted the specific implementation to the generals in front.

Since Li Chengding thought that he wanted to withdraw from the army, it must be forced by the situation and had to retreat.

Of course, although the Wu army retreated, this did not mean that Shi Jingjiao should be spared.

In July of that year, 10,000 Wu troops and 5,000 soldiers of the forbidden army landed near Yuguan in the western Liaoning corridor, and built a new city on the basis of the old city.

This Yuguan north leans on the mountain, the south is bordered by the sea, the distance is not more than a few miles, the terrain is very dangerous, the Sui Kaihuang three years was built here to build the Yuguan City, since then it has been an important town of the border pass, there are heavy troops stationed.

However, in the Jin period, after Li Cunqiao seized Youzhou, Zhou Dewei, a veteran who was responsible for guarding Youzhou, relied on his courage and did not repair his border preparations, which led to the abandonment of Yuguan, and the Khitans had no worries about the future, and since then they have been in the army every year.

At this time, the Wu army landed here and built a new city, and the news spread, which immediately caused great panic in Shi Jingjiao.

After realizing that the actions of the Wu army would pose a great threat to him, Shi Jingjiao mobilized troops on the one hand, and sent people to ask the Khitans for help on the other hand, and stated the stakes.

In August of this year, Shi Jingjiao sent an army of 30,000 and a combined Khitan army of 50,000 to arrive at Yuguan.

However, at this time, Yuguan had already built a new fortified city, which had a large amount of grain and grass in reserve, and more importantly, dozens of artillery pieces were placed on the city wall, and the defense was strong enough to make people fearful.

The 5,000-foot army under the command of Liu Renzhen, the general of the Wu army, was responsible for guarding Yuguan, although there were not many troops, but all of them were the most elite soldiers.

In the face of the attack of Shi Jingjiao's army and the Khitan coalition army, Liu Renzhen was not in a hurry and relied on the strong city to resist.

In the following ten months, the combined forces of Shi Jingjiao and the Khitan besieged Yuguan, and the army attacked the city day and night.

However, the Wu army relied on sea ships and could be constantly supplied; Moreover, Liu Renzhen was well versed in the way of defending the city, although he was surrounded by the enemy, he was calm and calm, and kept the city as stable as Mount Tai.

The combined forces of Shi Jingjiao and the Khitans not only failed to break through the Yuguan, but suffered numerous losses under the pass.

Until June of the following year, 20,000 elite Wu troops came from the sea, landed directly behind Shi Jingjiao and the Khitan coalition army, and joined forces with the defenders in the city to defeat the enemy.

The Wu army then pursued the enemy to Liucheng, where they engaged the enemy, again won a great victory, and captured Pingzhou to the north.

By the time the remnants of the coalition army finally fled back to Youzhou, the number of troops was less than 5,000.

After this fiasco, Shi Jingjiao's vitality was greatly damaged, and the Khitans suffered heavy losses, Yelubei took this opportunity to lash out in the country, pointing out that Shu Luping rashly interfered in the war in the Central Plains and brought disaster to the Khitan.

In July, Li Chengding once again led a large army against Shi Jingjiao, but this time, the Khitans had just experienced a crushing defeat, so no reinforcements were sent.

And Shi Jingjiao's main force had been wiped out before this, so the Wu army fought extremely smoothly along the way, and by September, Shi Jingjiao's territory had been captured, and only Youzhou was still in Shi Jingjiao's hands.

However, at this time, Shi Jingjiao also understood that the general trend had gone, so he asked the Wu army to surrender, but Yang Wu refused his request to surrender on the grounds that Shi Jingjiao colluded with the Khitans to bring disaster to the Central Plains, and ordered the Wu army to attack the city.

In October, the Wu army broke through Youzhou, and Shi Jingjiao and his whole family set themselves on fire in the mansion and died.

Then, the Wu army continued to the west, launching attacks on Datong, Daizhou, Ulzhou and other places, and the forces in these places, including the Fuzhou Zhejia and the Linzhou Yang family, surrendered to the Wu army.

At this point, the sixteen states of Yanyun, which originally fell into the hands of the Khitan and had a great impact on the Central Plains, were completely occupied by the Wu army, and the defense line of the Wu army in the north was formed.

Next, the Wu army set its sights on the Northern Tang regime, which was entrenched in Taiyuan.

The strength of the Northern Tang Dynasty was far from being comparable to that of the Later Tang Dynasty, and in the face of the attack of the Wu army, it was quickly impossible to parry, and by August of the 23rd year of Wuyi, Li Jiqi saw that the general trend had gone, and finally surrendered to the Wu State.

At this point, since the Middle Tang Dynasty, the situation of the division of the world's feudal towns and endless battles has finally moved towards unification in the hands of Yang Wu.

For the next twenty years, Yang Wu continued to recuperate and develop production, while at the same time working to eliminate the effects of the secession of the feudal towns.

Han Zhu, the envoy of Shuofang Jiedu, and Li Congyi, the envoy of Fengxiang Jiedu, both spontaneously wrote to Wu after the unification of the world, requesting internal relocation and handing over the power in their hands; Only Xiazhou's determination of the difficult festival made Li Renfu not take any action.

In the twenty-sixth year of Wuyi (933), Li Renfu died of illness in Xiazhou, and his son Li Yichao inherited the power, and at the same time sent an envoy to Luoyang, hoping to get Yang Wu's canonization.

However, Yang Wu was originally eyeing Xiazhou, where is he willing to let Li Yichao succeed him now? Therefore, Yang Wu issued an edict asking Li Yichao to come to Luoyang in person to meet him.

Li Yichao was worried that he would be imprisoned after arriving in Luoyang and would not be able to return to Xiazhou, so he did not dare to come in person, but only sent his son to come, and at the same time made a big deal in Luoyang to buy the powerful people in the court, hoping that they would help to talk about the item, so that Li Yichao could succeed to the throne smoothly.

However, this matter was inquired into by Cheng Zong, the new commander of the Long Sword Capital, and reported it to Yang Wu.

After learning the news, Yang Wu was immediately furious, and on the one hand ordered a thorough investigation of the matter, on the other hand, he ordered Liu Renzhen to lead an army of 60,000 to conquer Xiazhou.

The city of Xiazhou is extremely strong, so it is rumored that it was built by Helian Bobo; And the party Xiang Tuoba clan has been in Xiazhou for a long time and has long been entrenched, so this time the battle of the Wu army did not go well, and even the whole process was very difficult.

On the one hand, Li Yichao relied on Jiancheng to resist, and on the other hand, he recruited party tribes and plundered the grain road of the Wu army day and night, and the military rations of the Wu army were transported from Guanzhong to Xiazhou, and they were attacked and harassed along the way, with great losses, and the consumption of money and grain was even more incalculable.

In the face of such a situation, Yang Wu still did not give up, and once again ordered to send 60,000 elite soldiers, recruited 100,000 people, and was specifically responsible for transporting grain and grass, and sent someone to pass on the edict to Liu Renzhen, asking him not to think about the rear, and to break through Xiazhou and exterminate the Tuoba clan.

This siege battle was not much better than the siege of Yang Liu back then, and it lasted for more than half a year.

Although Li Yichao exhausted his means, he was finally defeated in the face of the absolute power of Wu State.

In the twenty-seventh year of Wuyi, the Wu army broke through Xiazhou and captured all the Dangxiang Tuoba clans to Luoyang to show the public.

Next, in order to further eliminate the influence of the Tuoba clan, Yang Wu ordered Liu Renzhen to be the northwest economic strategy, and continued to lead the army to clean up the party tribe that had helped Li Yichao during the siege, and after a bloody massacre, the foundation of the Tuoba clan was finally completely severed.

By the time of the 30th year of Wuyi, the population of Wu had exceeded 40 million, and the annual income of the state treasury exceeded 30 million.

The abundant fiscal revenue ensured that Wu had enough national strength to expand abroad.

After eliminating the envoys of the Xiazhou Dingnan Festival, the state of Wu continued to attack westward, recovering the Hexi corridor, and the Guiyi army led by Zhang Yichao's descendants surrendered to the state of Wu.

Next, the Wu army continued to the west, extending its power back to the Western Regions and Qinghai, and the countries of the Western Regions sent envoys to Luoyang to meet each other, just as they did when the Tang Dynasty was prosperous.

In addition to expanding westward, Wu also did not forget its overseas territories, although Wu did not continue to expand overseas territories in recent years, but the original territory has been greatly developed in the past 20 years.

Many new seaport cities appeared overseas, further promoting the prosperity of overseas trade, and customs revenue became an important source of finance for the state of Wu.

Of course, in terms of foreign affairs, the most important war of Wu was the war with the Khitans.

In order to eliminate the threat of the Khitan, Wu launched five large-scale conquests, using a maximum of 200,000 troops, even if the number of troops was small, there were 50,000 or 60,000 troops.

In these five wars, the Wu army was not smooth sailing, but had failures, even fiascos, and the biggest loss was the third dispatch.

In the 33rd year of Wuyi, Yang Wu ordered Li Chengding and Liu Renzhen to lead 60,000 troops out of Yuguan and enter the Khitan, but they were ambushed by the Khitans, and the two armies were defeated, losing nearly 20,000 soldiers.

Such a defeat was completely unacceptable to Wu State, and only three months later, Yang Wu, who was embarrassed and angry, ordered to conquer the Khitan again, which was the fourth expedition to the Khitan.

And this time, Yang Wu not only dispatched an unprecedented 200,000 army, but also decided to personally lead the army.

After the 200,000 troops set out from Yuguan and penetrated more than 800 miles behind enemy lines, the scouts finally found out that the Khitan lord Yelu Deguang was in Songmo Mansion at this time.

So Yang Wu ordered Li Chengding to continue to lead the infantry army to Songmo Mansion, and he himself led 20,000 cavalry, no one took off his armor, his horse did not leave the saddle, and he sneaked all the way.

At this time, the Khitan army had just defeated the Wu army a few months ago, so everyone from Yelu Deguang to ordinary soldiers did not expect the Wu army to come back so soon, so they did not have any defense against the actions of the Wu army.

A few days later, the cavalry led by Yang Wu quietly appeared behind the Khitan army and launched a surprise attack, Yelud was caught off guard and fled in a hurry with thousands of cavalry, but crashed into the ambush of Li Chengding's troops, and finally escaped with only a few dozen people in embarrassment.

In this decisive battle, the Wu army won a complete victory, capturing more than 200 Khitan nobles, capturing more than 80,000 ordinary soldiers, and capturing nearly one million horses, cattle, alpacas, and sheep, but its own casualties were negligible.

Such a gorgeous victory made Yang Wu's prestige further shake the United States, but the Khitan, who suffered a heavy defeat, was greatly damaged, and after that, he was no longer able to fight Wu in the front.

The Khitans' raids on the Central Plains also stopped for several years, and did not reappear until a few years later, but at that time, the Wu army launched the fifth war against the Khitans, and also won a great victory, and continued to maintain strong pressure on the Khitans.
