Stone Castle City, standing on the bank of the Huangshui River.

It was a small city that could accommodate no more than 50,000 soldiers and civilians.

However, it is a very important barrier in the western part of the Central Plains.

As for why.

Mainly because of the topography of Stone Castle City.

The stone castle city is built on the mountain, backed by the mountains, and in front of it is the Loess Plain.

Less than 100 paces away from the city walls, there is a trail about 300 paces long.

If you want to attack the city, you must first pass this path.

And the size of this trail can only accommodate two or three hundred people at most for siege warfare.

It is impossible to develop the advantage in troops, which is why thousands of Tuyuhun soldiers rushed last time, but they were blocked by less than 2,000 soldiers.

From this point of view, the military position here is enough to show.

If Tuyuhun occupies this place, he can use Shibao City as a stronghold and continue to expand eastward.

The Tang Dynasty, on the other hand, could expand westward if they occupied it.

If it is placed in other dynasties, this place is like a chicken rib.

After all, the land to the east is the real fertile land.

The land in the west is barren, especially Tuyuhun is still a high-altitude area.

No one cares about their turf.

If it were in other dynasties, with the current aggressive political concept of Murong Fuyun, he might really be able to make Tuyuhun bigger and stronger.

It's a pity that they met Li Shimin.

Li Shimin was one of the few emperors who defeated the strong enemies in the east and north and turned to the west.

Because of this, the status of the military base of Stone Fort City is even more important.

……

When night falls, the sky is full of stars.

Two sentinels, one of them gossiping.

"You said this is all the case, why are you still keeping vigil? Could it be that he is afraid that a wild beast will attack the city? ”

The other chuckled and said, "Are you prepared, in case the enemy comes to attack the city, let's be prepared." ”

Hearing this, the sentry on the opposite side said nonchalantly: "Attack the city of a hammer." ”

"Now that General Duan and General Li have led people to their nest, how can they still have that ability?"

It was also when the two were chatting.

In the faint moonlight, dense figures had slowly poured out from the shallow hills in the east, heading straight for Stone Castle City.

Thousands of soldiers slowly advanced in the faint moonlight.

As they got closer to Stone Castle City, so did their speed.

It was when these people were less than two hundred steps away from Stone Castle City.

The two sentinels finally realized that something was wrong.

When he saw the figure under the city wall, one of them hurriedly shot the warning arrow into the sky.

With a piercing chirp, the Stone Castle City suddenly began to be noisy.

The two sentries did not dare to hesitate, and after shooting the arrows, they hurriedly wanted to close the city gate.

But the two of them, without even touching the edge of the city gate, were shot into hedgehogs by flying arrows.

Immediately afterwards, groups of Tuyuhun soldiers burst out with a shout and entered the city.

Datang is still too careless in the end.

They never imagined that the enemy army, which had been being chased and beaten by their own side, would suddenly reach the rear.

Many Tang soldiers were awakened from their sleep.

By the time they rushed out of the barracks, the enemy was already in sight.

Tang Bing didn't say a word, picked up the steel knife in his hand and fought with the enemy.

……

Inside the Castle Lord's Mansion.

The soldiers of the Qianzi Battalion and the elites brought by Li Tingxue also gathered.

Li Chengqian was also dragged out of the bed by Li Tingxue.

Now, in the Stone Castle City, except for the City Lord's Mansion, there are earth-shattering shouts of killing everywhere.

No matter how slow Li Chengqian's reaction was, he knew that there was an enemy army coming to sneak attack.

They never thought that there would be such a thing as an enemy attack.

The soldiers were basically taken away by Li Tao and Duan Zhixuan.

Even if Li Chengqian and Li Tingxue's guards are added, there are only 23,400 people in total.

And how many enemy troops there are, until now there is no accurate statement.

Li Chengqian had never experienced such a scene.

At that time, I was so scared that I didn't know what to do.

"Sister, what should we do now......"

"What else can I do?"

Li Tingxue sighed and said: "The number of enemy troops is unknown, so we can only kill them for the time being, and wait until the army comes back in the future to recover Shibao City." ”

After speaking, Li Tingxue immediately made a decision and ordered: "Everyone will go out of the city with me." ”

After speaking, she held a knife in one hand and Li Chengqian in the other.

With the team, they rushed towards the city gate.

Outside, there was already chaos, and soldiers fighting could be seen everywhere.

The Qianzi battalion and Li Tingxue's escort battalion were not spared, but they collided with the enemy's large force as soon as they went out.

There were two thousand men on their side, and the enemy army was even more.

After the two armies were in one place, the whole street suddenly became chaotic.

Cheng Huailiang and Changsun Chong are both at the forefront.

Cheng Huailiang himself comes from a family of military generals, and he has good martial arts skills.

Changsun Chong is an underestimated person in his eyes, and at this moment, there is a hint of inappropriateness in drawing a knife to fight against the enemy.

It's just that the battlefield is so big, how big a splash can the two of them make?

Most of the Qianzi battalion under Li Chengqian is a new army, and few of them have actually been on the battlefield.

Although the armor is bright, it looks majestic on weekdays.

But when it comes to real fighting, they're no different from embroidered pillows.

Often, one or two people had to be killed in battle in exchange for the death of one enemy.

Looking at these, the guys who used to chat with themselves died one by one in front of their eyes.

Li Chengqian's eyes were dull, as if he was stupid.

Cheng Huailiang, who was covered in blood, rushed to Li Chengqian: "Your Highness, the county lord, there are too many enemies, and the brothers can't stand it anymore." ”

Li Tingxue gritted her teeth and directly pushed Li Chengqian onto Cheng Huailiang's body.

"Promise me that you will take him out."

Hearing this, Cheng Huailiang was obviously stunned, and looked at Li Tingxue with a puzzled face.

Then, he was also relieved, and said with a smile: "County Lord, let's come." ”

"You can't, I can only do this."

Li Tingxue only said this sentence to Cheng Huailiang.

At this time, Li Chengqian also suddenly came back to his senses: "Sister, what do you want to do, don't do stupid things......"

"Your life is more important than your sister."

Li Tingxue glanced at Li Chengqian gently.

It doesn't matter what he says, no matter how he stops it.

She only waved the war knife in her hand violently and shouted: "Zuo Yiwei! Nine deaths without regrets! ”

As the words fell, she led more than a dozen people to kill towards the densest place of the crowd like suicide.

Immediately after that, the more than 1,000 guards also erupted in shouts at the same time.

"Zuo Yiwei, nine deaths without regrets!"

Subsequently, they rushed to the place where the crowd was most dense, as if they were suicidal.

They completely used their lives to open a bloody way for Li Chengqian's killing.

It was not until this time that Li Chengqian knew.

It turned out that Li Tingxue's guard battalion was Zuo Yiwei, the prince's pro-army who disappeared after the Xuanwumen Incident......

Seeing that he was still distracted, Cheng Huailiang couldn't care so much.

The diameter clamped him under the armpit, and he jumped on a frightened warhorse galloping over.

Cheng Huailiang took a deep look at Li Tingxue, who was fighting with his life in the crowd.

then escorted Li Chengqian all the way out of Shibao City.

And Li Chengqian kept looking at Li Tingxue in the crowd, and shouted his sister heartbreakingly......
