"My old Cheng ......"

The two ladies explained the incident to Li Yan, and begged Li Yan to save the lives of the 30,000 Tang troops and Cheng Yanjin.

They knew that it was not the imperial court that could save Cheng Biting Jin now, but the Dingbei Marquis who could defeat tens of thousands of elite soldiers in Cheng Biting Jin's mouth alone.

"The imperial court's reinforcements to Shanzhou were ambushed halfway? Liangzhou mutiny? Xue Yantuo and Tuguhun will meet outside the city of Shanzhou? ”

After Li Yan heard this, his brows immediately furrowed.

According to the original historical development, in the second year of Zhenguan, the relationship between Xue Yantuo and Tuguhun and the Tang Dynasty should not deteriorate.

Li Yan couldn't figure out the reason why these two countries suddenly invaded Datang for a while.

"Don't worry, I'll go!"

Although he couldn't figure out the reason, Li Yan didn't hesitate at all.

Regardless of the 30,000 army and Cheng Yanjin, Li Jing, and the situation of Zhang Dazhu and others in this army, Li Yan could not choose to sit back and watch all this happen.

Li Yan immediately ordered the subordinates of the Beihou Mansion to bring his war horse, and at the same time, Li Yan also returned to the room to change into a battle armor, and picked up the Fang Tian painting halberd that he hadn't touched for a long time.

A few minutes later, Li Yan set off quickly from the Dingbei Hou Mansion and headed all the way towards the west gate of Chang'an.

……

The person guarding the west gate of Chang'an today happened to be Li Yan's old acquaintance Shen Chao, who looked all the way in the direction of the city.

Judging from his contact with Li Yan these two times, this Marquis of Dingbei may have to ask His Majesty for instructions and personally go to the front line to rescue.

Sure enough, there was a faint sound of horses' hooves in the city, but what puzzled Shen Chao was that the sound of horses' hooves seemed to be only a war horse, could it be that this was not Dingbei Hou preparing to lead people to the expedition?

After a few breaths, Shen Chao saw the face of the comer, it was Li Yan who was fully armed.

"Li Xianhou went to Shanzhou to support according to His Majesty's orders?"

Shen Chao, as a soldier guarding the city gate, naturally had to ask clearly.

"Open the gates!"

Li Yan didn't have time to ink, he was afraid that he would see Zhang Dazhu and them on the battlefield when he was one step late.

"Yes!"

Seeing that Li Yan was so eager, Shen Chao didn't dare to ask in detail, he thought that Li Yan had got Li Shimin's will, so he had to urgently go to Shanzhou to help.

The city gate was quickly opened, and Li Yan quickly rode out of the city and traveled all the way west.

"Brother Chao, we haven't seen the paperwork! If you open the city gate like this, will you be held accountable? ”

The defenders on duty with Shen Chao asked.

"Since the Marquis of Dingbei went out of the city so openly, he must have received His Majesty's will, and the reason why he did not issue a document must be that the war is urgent and cannot be delayed."

Shen Chao didn't think that Li Yan would go out of the city during the curfew this time, and there was still no corresponding procedure, he thought that he was acting smartly.

"I see."

The defenders on duty with Shen Chao nodded thoughtfully, it seemed that they still lacked tempering, and they didn't even think about such a simple thing.

However......

After a stick of incense, the sound of horses' hooves came from the city again.

Wei Chigong led a Xuanjia army of 1,500 people from the direction of the imperial city.

"The old man was ordered by His Majesty to lead his troops to Shanzhou to relieve the siege and open the city gate quickly!"

Wei Chigong held high the holy decree and shouted urgently.

"Yes!"

Shen Chao didn't dare to slack off, and immediately helped open the city gate and let Wei Chi Gong and others pass.

When everyone left, Shen Chao looked into the distance with a little blindfolding.

Since the Xuanjia Army led by the Duke of E is the support force appointed by His Majesty, doesn't it mean that Li Yan, who rode out of the city alone before, has no documents?

Anyone with a brain can figure it out, His Majesty will not send two groups of people to support one after the other, especially one of them is Li Yan's solo ride!

"It's over! Dingbei Hou has no paperwork! ”

Shen Chao woke up like a dream and broke out in a cold sweat.

Although he had told Li Yan before that it was enough to go out of the city to register on the night shift, he also had to go to the city guard to go through the procedures temporarily.

The current situation is that he let others out of the city without any paperwork!

This is a violation!

Once exposed, then he will be punished with more than ten or twenty military sticks, and if the military department is held responsible, he may not be able to save his head!

So, Shen Chao decisively chose ......

"Xiaoliang, we haven't seen Dingbei Hou today! Dingbei Hou is out of the city in the daytime! And then it never returned! You remember! ”

Shen Chao decisively chose to conceal it, anyway, there were only the two of them on duty during this time period, and others didn't know about Li Yan's departure from the city.

“？？？”

The defenders called Xiaoliang were full of question marks, and they still hadn't figured out what was going on......

……

Li Yanke didn't know what was happening behind him, and he didn't know that Cheng Yanjin had followed him with the most elite Xuanjia Iron Horse in Datang, and was also on the way to Shanzhou to support.

Li Yan only knows now that Chang'an is about 1,600 miles away from Shanzhou.

Briefly estimate the normal marching speed of the army, and the time it will take for the battle report to return.

The army was supposed to have been ambushed after twelve or three days of marching, and then the messengers who broke through took two or three days to bring the news back to Chang'an.

(The time has been adjusted, and the previous article has been revised)

According to the speed of the rapid march of about 70 miles a day, the army was obviously far from reaching Shanzhou, and was ambushed at most at a distance of eight or nine hundred miles.

In other words, the place where the ambush took place should be in the territory of Lanzhou!

That is to say, now on the northwest border of the Tang Dynasty, there are already five continents such as Shanzhou, Lanzhou, Liangzhou, Ganzhou, and Shazhou in crisis!

If Tuguhun and Xue Yantuo were more courageous, maybe this battlefield might go deeper, and it was possible for the battle to spread to Ningzhou!

In such a battle situation, it is conceivable that the number of troops dispatched by the local government is at least twice as high as the Tang Army that went to support, not to mention more than 60,000 people!

"No! Gotta hurry! Otherwise, don't talk about Zhang Dazhu and them, it is possible that the Tang Army will be annihilated! ”

Thinking of this, Li Yan couldn't be calm at all, he didn't want to see Zhang Dazhu and the others die on the battlefield, and he didn't want to see the thriving face of the Tang Dynasty destroyed by aliens!

Therefore, Li Yan decisively entered "My World" and used all his gold mines, synthesized gold grains, made golden carrots, and used potions to quickly reproduce and accelerate horses.

With no regard for the cost, in just one hour, the acceleration horse has bred the fourth generation!

Li Yan exhausted his experience reserves, extracted them, and changed his mount!

The fourth generation of acceleration horses, with a maximum speed of 300 kilometers per hour!

Under normal conditions, the speed can be stable to 200 kilometers per hour!

At such a speed, once it soars, it will directly explode the speed of modern ordinary vehicles galloping on the highway!

"Full speed, run!"

Li Yan took the reins fiercely, picked up the whip and gave the war horse.

The speed is at the limit in an instant!

The wind blew on Li Yan's face, and Li Yan's physique exceeded the limits of the human body, and it was a little difficult to maintain balance, so he could only lie slightly on the horse's back.

The speed of every little thing of 300 kilometers burst out in an instant, and a man and a horse seemed to turn into a violent wind, quickly approaching the direction of the battlefield.

At this moment, an hour had passed since Li Yan left Chang'an, and he had already traveled more than two hundred miles away from Chang'an.

Counting the speed after changing mounts now, Li Yan will arrive at the battlefield in two hours!

……

At the same time, the city of Lanzhou.

Li Jing had already led his army into the city.

He never imagined that when they were still hundreds of miles away from Shanzhou, they were ambushed.

What's even more terrifying is that it was Xue Yantuo's army who ambushed them!

"Damn! Shanzhou is afraid that it is dangerous. ”

Li Jing stood at the head of the city and clenched his fists.

Since he joined the army, he has never fought such an aggrieved war.

The entire 30,000 army led by him lost thousands of people in the first ambush, and then fortunately, Li Jing reacted quickly and chose to retreat to Lanzhou, which was able to stabilize the battle situation.

It's just that Li Jing knows that once Shanzhou is broken and the main force of Tuguhun's army arrives, and they achieve a real rendezvous with Xue Yantuo, Lanzhou will not be able to stop them from continuing to move forward.

At that time, Datang will be in danger!

Just when Li Jing had a headache, the thick dark clouds in the sky accidentally dispersed a little, revealing a little moonlight, and the corner of his eye suddenly noticed that something was wrong under the city!

A group of Xue Yantuo's soldiers have already touched the city at some point! And still with a siege ladder!

"Enemy attack! Defend the city! ”

Li Jing roared at the tired soldiers on the city wall with a single voice.

Now there are no defensive equipment in the city, and the reserves of rolling wood and rockfall hot oil are insufficient, once Xue Yantuo's people are allowed to set up siege ladders, this Lanzhou City will not be so easy to defend.

"Archer, release the arrow!"

"Sword and shield hand, ready to go up at any time."

Li Jing was very helpless, these siege and defense battles were both tough battles, and there were not many tactics that could be used, which was basically a confrontation between troops and morale.

Therefore, even if Li Jing is known as the god of the Tang Dynasty, it is very difficult to tactically counter Xue Yantuo's army, and he can only personally command to boost morale and delay time.

"Kill!"

When Xue Yantuo saw that the night attack was revealed, he no longer concealed it and directly began to rush and kill.

They carried a rain of arrows to set up a siege ladder, and a group of muscular Xue Yantuo people were not afraid of death to resist the foot of the ladder, so that the army began to attack the city head-on!

"Storm the walls! The Tang army has been holding out for two days, and they won't be able to hold out for long! ”

Under the city, Lama Zhi roared excitedly, he was the main general of Xue Yantuo in this battle, and he was also the nephew of Xue Yantuo Zhenzhu Khan Yinan.

Originally, according to the results of the discussion between Yi Nan and the Murong clan of the Tuguhun royal family, they just wanted to go deep into the hinterland of the Tang Dynasty and obtain the magical crop called potatoes.

In fact, the two sides do not want to have too much contradiction with Datang.

However, when Dumozhi came to Datang as the main general, he suddenly found that Datang's border defense was quite empty.

Such a situation directly aroused the ambition of Timach!

He wanted to work with Murong Shun, the eldest prince of Tuguhun's expedition, to bite off a piece of meat on Datang!

Even if it were possible, Dumozhi would like to fight all the way to Chang'an, capture Li Shimin alive, and occupy the entire Central Plains!

It can be said that ambition has dominated Yamachi, and the current situation of the war has given him great confidence.

"Siege! Returner, die! ”

He personally commanded the battle, and he wanted to capture Lanzhou before the Tuguhun people conquered Shanzhou.

As long as the city of Lanzhou is broken, he will be able to go all the way east, and the army will go straight to Chang'an!

The plan seemed to be going quite smoothly, and a large number of Xue Yantuo soldiers attacked the city.

"General, the last general asks to take people out of the city and destroy their siege equipment!"

The battle damage on the city wall became more and more serious, and Zhang Dazhu seemed to think of something, and suddenly took the initiative to ask for his life.

"Nonsense! I know that you want to defend against Li Yan and want to stop the siege by destroying the siege ladder, but you are not Li Yan, if you take people out of the city, there is no possibility of survival! ”

Before Li Jing could react, Cheng Yanjin rejected Zhang Dazhu's proposal.

"General, count us in! A few of us rushed out together, with a hundred people, and we will be able to break through the siege ladder! ”

The next moment, Ge Dahai and the others also stood up.

They all thought of the scene where Li Yan destroyed the siege ladder with one hand, and figured out that the hope of really defending Lanzhou City and delaying time was to destroy the other party's siege equipment.

Seeing this situation, Li Jing was thoughtful.

The war has been going on for so long, and Li Jing has actually known the skills of Zhang Dazhu's group of people for a long time.

Among them, the trio led by Ge Dahai is superb in riding, and also has a strange beast (pig) with extremely fast speed

And Zhang Dazhu and the others are strong in physique and extraordinary in force, if they are superb in martial arts, they are even comparable to the group of generals standing in the court.

If these nine people led people out of the city, they might really be able to destroy the siege ladder of Xue Yantuo's army.

Of course, as long as they leave the city, they must be gone.

"If you go out of the city, you may not be able to come back."

Li Jing calmly explained the truth to Zhang Dazhu and others.

"If you can't come back, you won't come back!"

"As long as we don't disgrace the boss, we are satisfied!"

"As long as we let us out, we will definitely destroy the siege ladder, and then kill another hundred and eighty barbarians, we will make a lot of money!"

The attitude of Zhang Dazhu and the others was extremely resolute, they would rather go out of the city and fight for their lives than wait for death in the city.

"Go! Remember, you must destroy the siege ladder! ”

Li Jing made a decision.

It was undoubtedly cost-effective to exchange the price of Zhang Dazhu's nine men and 100 other soldiers to form a death squad in exchange for the hope that Lanzhou could hold on for another day or even more days.

Sometimes, as a general, you should have this kind of cold-blooded and decisiveness.

"Sword and shield hands up! Archers empty the city gates near the enemy army! ”

In order to let Zhang Dazhu and the others get out of the city smoothly, Li Jing quickly arranged it, and a large number of arrows began to shoot, which quickly reduced the number of Xue Yantuo people near the city gate by more than seventy.

Inside the city gate, Zhang Dazhu and nine people led the newly formed hundred-person death squad to the city gate.

"After drying these two bottles of medicine, go out and kill the enemy!"

"This is given by the boss, drink it, and we will still be under the boss in the next life!"

"!"

The nine people took out the potion that Li Yan gave them and drank two of them directly.

The names of these two potions are the Acceleration Potion and the Strength Potion, respectively.

"Open the gates and kill them!"

With an order, the city gate slowly opened, and the hundred-person death squad went out of the city in an instant!
