Dou Rong is Wang Mang's last years, occupy the five counties of Hexi to protect themselves, Guangwu Emperor Liu Xiu called the emperor, Dou Rong decided to return to the Han Dynasty, was awarded by Liu Xiu as Liangzhou Mu, from the hustle and bustle, was named An Fenghou, "Dou Rong returned to the Han" has also become a famous allusion, talked about.

An Xinggui used Dou Rong, who also occupied the land west of the river, to persuade Li Liang at this time, which can be said to be both appropriate and convincing.

However, at this time, Li Liang was unwilling to surrender to the Tang Dynasty, and he said unhappily: "With the strength of the mountains and rivers in the Hexi region, although they are strong, what can they do with me?" You came from Chang'an, did you lobby specifically for Li Tang? ”

After An Xinggui saw Li Liang's expression, he knew that even if he persuaded again, it was useless, so he hurriedly apologized to Li Liang and said: "When the minister hears that the rich and noble do not return to his hometown, it is like a brocade cloth traveling at night, and the whole family of the minister is subject to the honor of His Majesty, how can he be willing to belong to the Tang Dynasty?" The previous words were just to present my thoughts, and it is up to you, Your Majesty, whether it will work or not. ”

After Li Liang listened to An Xinggui's words, his face softened slightly, but after An Xinggui retreated, he immediately secretly united with his brother An Xiuren and prepared to attack Li Liang.

After Li Yin led the army to Jincheng, he immediately began to arrange the troops.

At this time, Li Liang asked Shangshu's left servant to shoot Cao Zhen with more than 100,000 troops, and went to the border to confront Li Yin, while he was in the capital Guzang City.

However, not long after Cao Zhen left Wuwei with his troops, there was an urgent report that Fu Yun, the Khan of Tuyuhun, sent troops to attack Hexi County, and almost at the same time, Cao Qiong, the Xirong envoy of the former Sui Dynasty, also entangled many rogues, bandits, and rebel forces, and launched an invasion of Hexi together.

These forces, each of which is not a lot of people, but the total number is close to 20,000 people, and at this time, they are attacking together, the momentum is very huge, and it directly threatens the flank of the Hexi region.

Li Liang didn't dare to underestimate it, and immediately personally led 80,000 troops out of the capital, intending to solve the quick battle and solve Fu Yun and Cao Qiong, the clowns who jumped off the beam in his eyes.

An Xinggui and An Xiuren brothers each found an excuse and continued to stay in Guzang City, not although Li Rail went out to fight, at this time, Guzang City, after Shangshu's left servant shot Cao Zhen and Li Rail successively led the troops away, it has become quite empty, with only more than 20,000 people defending, of which more than 8,000 people can be controlled by the An family.

The day after Li Rail led his troops to leave Guzang City, An Xinggui and An Xiuren brothers entangled the slave soldiers of the An family and the soldiers of Guzang City under their control, and suddenly attacked, attacked and killed some officials and generals who were still loyal to Li Rail, and then waved their troops to capture the palace of Liangguo and various city gates, and controlled Guzang City in their hands.

Subsequently, An Xinggui publicized the news of the rebellion in Guzang City to Li Liang and Cao Zhen to disrupt the morale of the two armies.

After Li Liang learned the news, he was immediately shocked, and he couldn't control the people who were invading Hexi, Fu Yun, Cao Qiong and others, so he immediately transferred the army and fought back against Guzang City, after all, he could lose other cities, even the imperial capital.

After hurriedly returning to Guzang City, Li Liang let people scold under the city for a while, and after seeing that An Xinggui and An Xiuren brothers did not show the slightest sign of surrender, they immediately commanded the army to attack the city.

After three days of attack and defense by both sides, Guzang City was already in danger, Li Liang couldn't help but be overjoyed when he saw victory in sight, but at this moment, he suddenly heard a thunderous sound behind the army, and the rear army became a little disordered.

"What's going on!" Li Liang shouted loudly to the left and right.

"Your Majesty...... Your Majesty, it seems to be the army of the Tang Dynasty......" The guards beside Li Liang said tremblingly, and stretched out his hand to point to the dragon flag moving in the wind in the distance.

"Why did Li Tang's army appear here? Cao Zhen was defeated so quickly? Li Liang's heart had completely become a little flustered at this time.

Soon after the Tang army appeared, it immediately launched an attack on Li Rail's army, and for a while, shouting to kill the heavens, Li Rail's rear army turned on their backs for a while, and they were powerless to resist.

"Your Majesty, let's retreat first, and then make plans, otherwise it will be too late!" Some close ministers shouted to Li Liang anxiously.

The morale of Li Liang's army was not high, and he was already a little tired after storming the city for three days in a row, how could he resist the sudden attack of the Tang army at this time?

Besides, they are still facing the most elite troops of the Tang Dynasty under the command of Li Yin, the king of Jin!

"The whole army retreats to Fanhe City!" Li Liang made this decision with a pale face.

Fanhe City is the closest big city to Guzang, the capital of Liangguo, in the northwest of Guzang City, after Li Liang made the order to withdraw his troops, he fled to the northwest with his army.

When he learned that An Xinggui had captured Guzang, the capital of Liangguo, Li Yin sent an envoy to recruit Cao Zhen, the left servant of Liangguo Shangshu who was confronting him, Cao Zhen did not agree, but he did not directly object, and respectfully sent Li Yin's envoy out of the camp.

Then, Cao Zhen led his army and withdrew to Baishan in the southwest of Wudu County, where he set up camp and completely gave way for Li Yinxi to enter Guzang.

Cao Zhen did this, on the surface, he planned not to help each other, if Li Yin could defeat Li Rail, he would surrender to Li Yin, if Li Yin could not defeat Li Rail, then he had to continue to be a courtier back to Liangguo.

So, Li Yin entered Wudu County unimpeded and went straight to Guzang City to kill.

When the army was preparing to march west, Fang Xuanling was a little worried that Cao Zhen was playing some conspiracy, in case he came to attack from behind, it would not be good.

Although Li Yin felt that it was unlikely that Cao Zhen would do this, he was careful to sail the Ten Thousand Years Boat, and still let Su Dingfang take more than 10,000 men and horses to ambush the troops halfway.

Although Cao Zhen did not intend to attack Li Yin, some of his subordinates were still loyal to Li Liang, and at dawn he led more than 20,000 horses out of the camp and killed Li Yin's army, but was defeated by Su Dingfang's ambush......

If Li Yin hadn't heard Fang Xuanling's words, he was afraid that the situation would be very different at this time.

When Li Rail fled to Fanhe City with his army, Li Yin also took advantage of the victory to pursue, Li Rail's more than 80,000 troops, killed, surrendered, and scattered, when entering Fanhe City, there were less than 40,000 people around, and the morale of the army was extremely low.

After Li Yin led the army to surround Fanhe City, he asked people to go to the city and proclaim loudly: "The Tang Dynasty is only here to destroy the cruel and unscrupulous Li Rail, and those who dare to help him will be killed by the three clans, and those who abandon the city and surrender will have the same title as before, and they will be hired!" ”
