Two months ago, Miao Jiang.

In the face of Li Maozhen's 12 mountains that could not survive when he asked for help, after Yuan Tiangang came to Miaojiang, it was like a group of people, not only publicly announcing that Chi Li was a rebel and a sinner in Miaojiang, but also actively helped Yuan Tiangang search for his whereabouts.

With the cooperation of the Twelve Mountains, Chi Li was killed by Yuan Tiangang after hiding for half a month, and the soldiers and gods he refined were all destroyed by the Long Xiang army.

May of the third year of Datang Tianji.

The more than 10,000 Longxiang troops who will be driven back were still handed over by Yu Fei to Li Maozhen and Guo Wei to command, and set off from Changshan as a partial division to cut off the back road of the Liao army.

On May 23, the Tang and Liao sides met in Weizhou, and although Fu Yanqing, the envoy of the Tianxiong Army, who was the head of the land, was extremely angry with Yu Fei's move to cut the domain, he was extremely carried by the Qing in the face of foreign enemies, and beheaded the Liao envoy who came to persuade him to surrender, and sent his head to Yu Fei.

In the context of Pinglu, Yiwu and other feudal towns one after another to take refuge in the Liao State, Fu Yanqing's action is extremely rare.

Yu Fei also reciprocated the favor by sealing Fu Yanqing as the king of Yiyang County and temporarily leading the Tianxiong army.

Since June, Yu Fei has led a large army to fight with the Liao lord Yelu Deguang in Weibo, and the Liao State, which has suffered a loss, faces Yu Fei, although his troops are several times that of Yu Fei, but he seems cautious and never rushes forward.

And when Yu Fei and Liao fought in Weibo, Li Yu of the Southern Tang Dynasty also ushered in a special guest.

"Your Majesty, now Li Fei is fighting with the million-strong army of the Liao State in Weibo, at this time, as long as Your Majesty's Northern Expedition defeats Bianliang, you can cut off the back road of Li Fei's army, as soon as Li Fei dies, the whole world will be Your Majesty's, Your Majesty should not hesitate."

Li Yu watched Li Siyuan talk eloquently, and couldn't help but fall into deep thought, and only said after a while:

"If Li Fei is defeated, won't the Khitan million-strong army take advantage of the situation to seize the Central Plains? Isn't that a national sinner? ”

Li Siyuan smiled and said:

"The Khitan is just a Hu person, occupying Yanyun is already the limit, he dares to peep into the position of the emperor of the Central Plains, which is the time of his defeat."

"Oh?"

Li Yu was puzzled, looked at Li Siyuan and waited for him to explain.

Li Siyuan bowed before saying:

"Your Majesty, please see, the Khitan went south twice, it seems to be overwhelming, but there are prerequisites, the first time is that Xiao Wang's son-in-law led the way, and many knots made one eye open and one eye closed, and this time it was Li Fei who made a faint move, and the world was not yet sitting, so he was in a hurry to cut the domain, which led to the dissatisfaction of many knots, which allowed the Khitan to come to Weibo without hindrance."

"As long as the Liao lord dares to peep into the throne of the Central Plains, he will inevitably be counterattacked, how many Khitan people are there, and how many Han people are there? Those knots are not vegetarians either. Your Majesty can rest assured. ”

Li Yu nodded and shook his head:

"It's still inappropriate, now that the country is unstable, there are still many people loyal to Yang Pu, and there is Wu Yue to contain it, once I leave, I'm afraid there will be big changes, inappropriate, inappropriate."

Li Siyuan heard Li Yu say this, pretended to be thoughtful, and said after a while:

"That sent a general to lead the troops?"

Li Yu just shook his head and said, "It's not appropriate."

At this time, Li Siyuan suddenly sighed and said:

"It seems that Your Majesty doesn't believe in Xiao Wang, just let Li Fei's shaft win the world, Your Majesty take care, the foreign minister has left."

Li Yu just smiled and watched Li Siyuan's performance, Li Siyuan said that he was going to leave, but his feet never moved.

"Okay, Li Siyuan, you don't have to play it anymore, I can also tell you the bottom, my Tang Dynasty does not have the power to unify the world for the time being, even if Li Fei dies, it will be a wedding dress for nothing, if you want to borrow soldiers, I can give you 20,000 soldiers, but after you succeed, I want Xiangyang and Bashu."

Li Siyuan also suddenly laughed at this time:

"Your Majesty has such a big appetite, this is to sit down in the southeast according to the Yangtze River natural risk. Good... Xiao Wang agreed. ”

......

In September of the third year of the opening of the Tang Dynasty, it has been a year since Yu Fei sent troops from Chang'an, and he has been in a tug of war with the Liao lord Yelu Deguang in Weibo for more than three months.

The soldiers and horses of Taiyuan and Luoyang also joined Yu Fei one after another, and the number of troops also reached 180,000, and the gap with the Liao army was less than double.

And Yelu Deguang has been defeated in the past three months, and the morale inspired by avenging the first emperor has been exhausted, plus there are more and more soldiers and horses in the Tang army, and he began to have the idea of retreating, but he has been dissuaded by Shi Jingjiao, saying that the big change is imminent, and the Tang army will be completely annihilated immediately.

That's what kept Yerod light going.

October 13 of the third year of the opening of the Tang Dynasty.

Li Siyuan took 20,000 soldiers and horses borrowed from the Southern Tang Dynasty, set out from Hefei, went out day and night, and after more than ten days of marching, came to Bianliang, relying on the fine work left in Bianliang to open the city, captured Bianliang in one fell swoop, and cut off Yu Fei's logistics.

In the camp of Wei Bo's Tang Army, as the messenger sent back the news of Bianliang, everyone in the big tent was a little flustered, even Wang Yanzhang, who had experienced a hundred battles, was no exception.

"Your Majesty retreat, let's go back to Taiyuan first, and fight again next year."

Everyone in the tent heard Wang Yanzhang's words, and they all nodded, it is indeed the best policy to retreat to Taiyuan with grain and grass.

Yu Fei couldn't deny it, just looked at the map in front of him.

At this moment, a somewhat immature voice sounded.

"Congratulations, Your Majesty, the fighter plane has arrived, and the defeat of the Liao State is imminent."

Yu Fei looked at Chai Rong, who was only fourteen years old, and said with a smile:

"Oh? All the generals want to retire, how dare you speak wildly, you little halberd? ”

After Chai Rong bowed, he said:

"Your Majesty, the elite of our army is several times that of the enemy, Your Majesty is wise and does not know how many high Liao lords, we have been entangled here, but because the Liao lord is timid and does not dare to fight a decisive battle, this has been tugging and seeing, and now our army's grain road is cut off, the Liao lord will lead a large army to attack, as long as our army is not chaotic, the Liao soldiers are definitely not our army's opponents, how is this not an opportunity to break the enemy?"

Everyone looked at each other, only Yu Fei suddenly laughed and said:

"Okay, at such a young age, you have such insight and courage."

After praising Chai Rong, Yu Fei stood up and shouted:

"The people will obey."

"The last will be..."

"Wang Yanzhang, you will take 10,000 cavalry to the Liao army camp tonight to provoke, it will not dare to come out, after the sky is completely dark, you will go east to temporarily go to PY to station, and after the Liao army leaves, you will take Bozhou to cut off his back road."

"The last will obey."

Yu Fei nodded, glanced at everyone in the tent again, and said:

"The rest of the generals, tonight the third watch camp will go to Xiangzhou."

"The last will obey."

......

On October 15, the third year of the opening of the Tang Dynasty, the grain route of the Tang army was cut off, and Emperor Shizu led the army to withdraw to Xiangzhou, and the Liao lord Yelu Deguang led a million troops in a vain attempt to swallow up the 170,000 Tang army.

The two sides fought in Xiangzhou for two days, the Liao army was defeated, and Yelu Deguang led the army to retreat to Bozhou, not wanting Bozhou to be occupied by the king of Nanping and Wang Yanzhang, so he had no choice but to continue to retreat north.

And Emperor Shizu pursued and killed all the way, killing countless prisoners.

When the Liao lord retreated to Youzhou, he found that Youzhou had been lost, and was once again pursued and killed by Guo Wei, the king of Pingyang County, and Li Maozhen, the king of Qi, the uncle of the country, and was finally beheaded on the bank of the Lushui River.

At this point, the vitality of the Liao State was greatly damaged, so it could only abandon its ancestral land, move westward, away from the Tang Dynasty, and finally re-establish the country in the west of Central Asia, known as Western Liao in history.

In January of the fourth year of the opening of the Tang Dynasty, the Tang army broke through Bianliang again, the traitor Li Siyuan burned the Bianliang Palace, self-immolation and died, and the rest of the rebellious Jiedu envoys were also destroyed one by one within half a year, which lasted a year and a half, and the Tang Dynasty officially unified the north.

In the whole world, only the Southern Tang Dynasty, the Southern Han Dynasty, and Wu Yue have not yet been unified.
