On the north shore of Weishui in November, Weishui is choppy.

Luo Siye's handsome flag arrived and was erected high.

After breaking through the four counties in a row, the Eastern Expeditionary Army reached the north of Chang'an, which was only more than 30 miles away from Chang'an City at this time, and from a distance, it was already possible to see the huge city on the plain through the Wei River.

It is an international metropolis with a circumference of 72 miles.

But in the eyes of Heiye, that is only the goal of his revenge, for a period of time, he has been thinking about how to attack this city, how to attack this city, and now he is stabbing the enemy and saving his wife and children.

"Under the festival, Chang'an has nothing to defend, as long as we attack, we can take it at any time."

Chang'an City is too big, this is only 30 years old to build the capital, the outer Guo City is more than 70 miles, but until the collapse of the great cause, the outer Guo city wall of Chang'an City was barely completed, the previous more than 20 years, has been only a door and no wall.

But even if Chang'an City has a city wall at this time, such a huge city, but there are only 20,000 people in the city to defend it, which is not enough at all.

The larger the city, the more troops need to be defended, which is basic common sense.

And Chang'an City is built on the plain, there is no danger to defend, when the outer gateway of Guanzhong is broken, and the defense layer of the inner line is torn apart, Chang'an City is just a huge and unsafe city to defend.

At the height of the Sui Dynasty, there were more than 500,000 people in the city alone, including the guards and forbidden soldiers, the emperor's concubines and palace attendants in the court, as well as the hundreds of officials and family members in the city, as well as a large number of people, craftsmen, monks, and so on.

However, since the Sui Rebellion, the population of Chang'an City at this time has decreased greatly, but there are still more than 200,000 mouths in the city, and more than 20 counties outside Chang'an City still add up to hundreds of thousands of people.

"Wait."

Siye looked at Chang'an City Road.

He was still waiting, waiting for Li Yuan's reply.

He had already sent an envoy to Chang'an City to meet Li Yuan, give Li Yuan a chance, let him return the detained wife and children, and then wait for Li Yuan to surrender, so as to avoid a war.

Even if Luo Siye has full confidence that he can take Chang'an City in the shortest possible time.

It's just that Li Yuan hasn't replied.

Little by little, the patience of the heirs is dissipating.

In the city of Chang'an.

Li Yuan sighed for a long time.

Faced with Luo Siye's ultimatum, he was very hesitant.

He was unwilling and worked hard to get to this point.

"Da Lang, what do you say we should do now?"

"Father, the son has sent someone to transfer Xiaogong from Tongguan to lead the army back to help, as well as the soldiers and horses of Lantian."

Li Yuan shook his head and smiled bitterly.

Even if they are brought back, what can they do?

Luo Siye attacked all the way to the city of Chang'an, Chang'an had no danger to rely on, but Luo Siye was strong and strong.

"Father, Wang Shichong was besieged by Li Mi for a few years, and he didn't also defend Luoyang, I don't think we need to be afraid of Luo Siye." Li Yuanji, King of Qi, said.

Li Yuan thought to himself, back then, Wang Shichong guarded Luoyang, how could he compare with now. First, Wang Shichong was able to hold Luoyang, the key is that Wang Shichong had been mastering Luoyang and the surrounding defenses earlier, even if Li Mi's troops came to the city in the later period, but there were other surrounding forces that had been holding Li Mi back.

What's more, Li Mi's soldiers and horses are not strong, and they can't be compared with Luo Siye's Eastern Expeditionary Army at all.

"Father, we killed Luo Siye's son, even if he surrenders, he won't let us go, it's better to fight." Built Road.

Li Yuan smiled helplessly, "Okay, the defense of Chang'an will be handed over to the crown prince, and the king of Qi will assist you." ”

The third day of November.

Li Yuan ordered the beheading of Luo Siye's envoy, and threw the envoy's head into Weishui in front of the Qin army, so as to strengthen the heart of resisting Qin.

Luo Siye was furious.

Ordered the soldiers and horses to cross the Weishui.

On the fifth day of November, the Qin Eastern Expeditionary Army crossed the Wei River by pontoon bridges in many places and surrounded Chang'an City.

After the siege of the city, Luo Siye issued a military order, strictly prohibiting all soldiers from leaving the camp without authorization, and not entering the nearby villages to loot and loot.

At this time, under the city of Chang'an, the three major clusters of the Eastern Expeditionary Army, 200,000 troops have arrived under the city, and about half of the more than half of the horses are still under the four counties.

Luo Siye spent ten days building siege equipment and persuading the soldiers and civilians in Chang'an City to surrender.

On November 15, the whole army began to attack the city, adopting the method of besieging the city on all sides, with 200,000 troops attacking the city together, and Li Yuan's 20,000 forbidden troops defending on all sides, overstretched.

On the third day of the attack, Hou Junji, the general of the Hexi Army, was the first to climb the head of Chang'an City and stand on his feet.

The constant Qin army jumped to the top of the city.

In the afternoon, Hou Jun Xinji, who had captured a section of the city wall, led his army into the city, captured an outer city gate, and opened it to lead the Qin army into the city. The Tang army retreated to Miyagi, but it only held out for half a day.

When it was about to get dark, Li Yuan set fire to the palace room in the palace and set himself and Taiji Palace on fire.

The Qin army extinguished the fire, Taiji Palace burned down half of it, but Li Yuan burned it to ashes, and before he died, he also dragged his wife and daughter to the funeral.

Looking at his wife and children turned to ashes, the heir industry burned with anger.

He ordered to search for Li Tang, Yu Jiancheng, Yuan Ji and others, and kill them all.

Li Yuan's infant son was not let go.

A night of hunting.

At dawn, the sun rose, and the soldiers of the heir were waiting for the order, and the soldiers finally put away their swords and soldiers and closed the camp.

On the third day after Chang'an City was captured, Huang Junhan, Dugu Huaien, and Li Zhongwen led 30,000 troops from Qizhou.

At this time, the soldiers and horses of Li Xiaogong of Tongguan and Li Shenfu of Lantian Pass, who were ordered to be the king of Qin, were always isolated outside Beijing and could not get close to Chang'an City.

The city of Chang'an was broken, and the heir sent an envoy to the Baqiao camp.

"What about His Majesty the Emperor?"

"I lit myself on fire and burned it to ashes." The messenger said.

"What about His Royal Highness the Prince?"

"After the city was broken, he hid in a green building, resisted when he was searched and discovered, and was beheaded on the spot."

"What about His Royal Highness King Qi?"

"Fleeing from the city, being hunted down, refusing to surrender, being shot by arrows."

·······

Li Xiaogong's face was ashen, "What do you want us to do now?" ”

"Surrender on the spot and give up resistance."

"What does Luo Siye plan to do with us, as well as our soldiers?"

"Together with Li Shentong and Li Daozong, you will be imprisoned first, and then you will listen to Emperor Hou's will. As for your soldiers and horses, as long as they are willing to surrender and join them, then they can neither be pursued nor sent home. ”

Li Shenfu asked, "Is my brother okay?" Is Chang'an City okay? ”

"Li Shentong was only slightly injured, Li Daozong was seriously injured, but he couldn't die, as for Chang'an City, you can rest assured, neither slaughtered the city nor killed innocents indiscriminately, and now it has settled down."

Li Xiaogong sighed, "I am willing to surrender." ”

"Surrender!" Li Shenfu also said helplessly.

The two of them had tens of thousands of soldiers and horses, and they abandoned their weapons and joined them.
