It's getting late.

Luo Cheng's eyes raised slightly, and he said loudly: "It's almost time, let's start." ”

"Drumming."

"Siege."

Luo Cheng's order was simple and clear, but it gave people an inexplicable confidence.

With the sound of drums, the morale of the army was boosted, and the battle began immediately.

As Luo Cheng said, he arranged for three groups of people to enter Chang'an City, with Jiang Song, Yuwen Chengdu, and Pei Yuanqing as the main generals, and one person attacked a city wall, leaving Li Yuan's exit.

Circumference is a routine since ancient times, and Luo Cheng naturally knows it.

In addition to the powerful generals of the three roads, generals such as Qin Qiong are also in the army. Such a battle is not only a charge, but also a good time to make achievements, and no one will choose to stay out of it.

Of course, Luo Cheng was not ready to make a move in person.

As the commander of the three armies, when he focuses on protecting himself, it does not mean that he can't do it at all, but the current situation has not yet reached the time for him to do it, after all, there is only one Li Yuanba.

Jiang Song attacked the east, Yuwen Chengdu attacked the north, and Pei Yuanqing attacked the south. With the continuous sound of drums, the three people and horses marched together, and they had already killed outside Chang'an City.

Jiang Song stood in front of the army, looking at the heavily guarded city tower, his eyes flickering slightly. He lifted the spear in his hand, and the original breezy and cloudy body was revealed, and the great momentum was revealed, which was extremely amazing.

Since it was all here, Jiang Song naturally had no reason to retreat, and the war was about to break out. Whatever the purpose, he will do his best to defeat the defenders.

"All the soldiers listened to the order and began to attack the city!"

Jiang Song let out a cold snort, announcing that the real battle had begun.

He took the lead, with a spear in hand, a soldier supporting the ladder charge, and siege engines and other equipment.

At this moment, the entire Chang'an City was covered with clouds, and the dim dusk scenery made people panic.

……

The huge movement outside the city, it is naturally impossible for everyone in the city to be unaware.

As the defenders' urgent report came, Li Yuan learned the news as soon as possible.

"The enemy army has begun to attack the city, this is the time when my Tang Dynasty is at stake, quickly go and gather the four people of Jiancheng and Shimin, and go to the city tower with me to help in the battle, and we must not let the enemy army break through Chang'an." Li Yuan's face was slightly gloomy, and he said in a loud voice.

With Li Yuan's order, the guards did not dare to delay, and hurriedly went to find Li Shimin's brothers. Now that time is urgent, if we delay for a few more moments, I am afraid that it will affect the overall situation, and the relationship is critical.

After being notified by the guards, Li Shimin and the others did not dare to delay, so they rushed to the city tower as soon as possible. Li Yuan had already dispatched troops and horses to gallop to the aid of the Quartet, and he also watched the battle from the city tower.

Seeing Li Shimin's brothers coming, he said: "The enemy's momentum is amazing, I am afraid that they want to break through Chang'an in one fell swoop, today is the time for the life and death of my Tang Dynasty, and I must not slack off." ”

Li Shimin and the others all said yes, and they all came to this point, how could they continue to make trouble. Even Li Jiancheng glanced at Li Shimin deeply and stopped talking.

Now is obviously not the time to make trouble, once Luo Cheng breaks through Chang'an, everyone present will have to be cool. This is not a matter of one person, even if Li Jiancheng is quite dissatisfied with Li Shimin, it is important to save his life.

Li Yuan nodded and said to Li Shimin: "Shimin, you let Yuanba prepare." Later, the big war will start, and I'm afraid he will have to make a move, so don't delay time. ”

This request is reasonable, and Li Shimin is as comfortable as he says.

The defense of the city on all sides has long been arranged, and now that the enemy army has begun to attack, they cannot change it.

After the arrangements were made, Li Yuan looked at the enemy army outside the city, this was the eastern city wall, and the main general outside the city was Jiang Song. Tens of thousands of elite divisions were waiting for them, and even Li Yuan felt a lot of pressure.

Strictly speaking, this is the first time Li Yuan has seen the real Yanyun elite. Previously, it was just the Snapdragon Army plus the coalition forces of various anti-kings, and the combat power shown was nothing more than that.

"The enemy is really fierce...... But my Datang soldiers and horses are not vegetarians, you should go all out to let the enemy know that my Datang cannot be bullied. Li Yuan paused and said loudly.

In fact, Li Yuan didn't have a bottom in his heart, and the pressure on him from the enemy army was too great. But he is the emperor of the Tang Dynasty, if even he shows his decline, there is no need to fight this battle.

Although the chance is slim, no one can be sure that Li Tang will lose, Li Yuan still wants to try. He wasn't willing to settle for it, and the situation didn't allow him to do that.

In addition, Li Yuan is not without a way out, he can fight here and make a decision after the battle situation is clear.

Li Shimin's previous reminder had already raised his vigilance, and there was a story of the three holes of the cunning rabbit since ancient times. Now that Li Yuan is in an embarrassing situation, he naturally has to find a way out for himself.

If Chang'an is broken, other places may not be able to hold on, and the only choice can only be outside the plug. Although Li Yuan was still a little unwilling, in such a dangerous situation, he had to make a decision.

Li Yuan did this very secretly, because he did not tell others, even Li Shimin and others did not know. After all, this is not a glorious deed, and it is better that fewer people know about it.

If the situation is really not good, Li Yuan's move is far-sighted.

Clearing the thoughts in his heart, Li Yuan continued to look outside the city, and at this moment, Jiang Song had already led people to charge. It is to be expected that a major war will start from here, and the enemy army will attack from three sides.

Li Yuan naturally understood the principle of missing one of the three in this way, but once the situation began to tilt, he could only kill from the West Gate. Even if there was an ambush by Yan Yun among them, he had to go there, and there was no other way.

Like Li Yuan, Li Shimin also looked at the outside of the city with a slightly gloomy face, the enemy army was in such a posture as soon as he came, could it be that he wanted to break through Chang'an in one fell swoop, but Chang'an was different from Tongguan.

Compared with others, Li Shimin undoubtedly knows more about Luo Cheng. Although Luo Cheng is very strong, he will never do something that he is not sure of, which shows a problem, Luo Cheng must have other preparations.

Relying solely on the three-way army and these ladder engineering vehicles, it was impossible to break through their defense line. Unless Luo Cheng has other preparations, and these are all existences that Li Shimin and others don't know.

Slowly exhaling a breath of turbidity, Li Shimin forcibly calmed himself down. The worst outcome has not yet appeared, which means that you still have a chance, and if you think too much, you will be suspected of unfounded worry.

At the same time, Jiang Song had already led Yan Yun's elite siege.

The defensive line arranged by the defenders had been broken through by them one by one, and the ladders were erected on the city walls, and many soldiers struggled to climb them, wanting to kill the castle tower and snatch the battle merits.

Even if they were eager to fight, the army still did not lose order, and everything was going on in an orderly manner.

The beating of the drums continued, and the rousing sound boosted morale.

Luo Cheng's eyes were also focused on the city wall, he knew very well that this was just the beginning, the real show was still to come, and he must be able to give Li Yuan a great surprise.
