They had seen a valley before, the valley was not big, it was backed by mountains, and the mountains on both sides were fairly steep.

In this way, once the enemy army came to attack, they could only attack from the front, and the width of the front was only more than 20 feet, so it was definitely not a problem for more than ten thousand elites of the Tang Dynasty to want to defend.

"The valley is not bad, but you have to understand one thing. If it is too easy to defend and difficult to attack, then how can Gao Yanshou bite our army so hard?"

"Only by showing a flaw in front of the enemy army and making them feel that they have a chance of victory, can Gao Yanshou's troops be dragged here to death."

"Furthermore, this place happens to be on the main route for our army to withdraw to Liaodong City. Our army could not withdraw in time, so we decided to stick to it and wait for help. It is reasonable and more reasonable. It can also dispel Gao Yanshou's doubts."

Facing the explanation of the Great Tang Army God who is holding the wisdom pearl, Cheng Chubi and Su Dingfang could only roll their eyes in unison and have nothing to say.

Li Jing pursed his lips, patted the dilapidated city wall rammed with earth, saw that Cheng Sanlang's eyeballs were dripping and turning around without making a sound, he couldn't help laughing.

"Cheng Sanlang, if you have any ideas, just tell me."

"Uncle, my nephew has counted the firearms His Majesty left for us before. If we want to hold here for a few days, there shouldn't be much problem."

"If uncle can trust my nephew, please ask my uncle to let my nephew lead the musket battalion to come here to set up, so that I can take care of my uncle at that time."

"Okay, since you have an idea, then do it yourself. At noon tomorrow at the latest, the Koguryo soldiers and horses led by Gao Yanshou will arrive at the camp. You don't have much time."

"In time." Cheng Chubi showed a confident and calm expression.

The forty cannons were all drawn by livestock, and the soldiers of the Musketeer Battalion commanded by Cheng Chubi were all military generals who came from the children of martial arts, and everyone had horses.

Moreover, during this period of time, under Xue Rengui's strict training, these musketeers were able to shoot targets no matter they were on a boat, on land, or on horseback.

This is why Cheng Chubi attaches so much importance to the Musket Battalion.

When Cheng Sanlang and the others escorted the forty cannons, they rushed to the entrance of the abandoned town day and night.

Gao Yanshou, the North Goguryeo Sasa, commanded 20,000 Goguryeo elite and 50,000 northern Mohe barbarian soldiers, and rushed towards the camp of the Tang Dynasty.

Gao Yanshou, who was nearly fifty years old, as a general of Goguryeo, originally wanted to stick to the rear of the city, but he couldn't resist the stern words of Nayuan Gai Suwen.

He had to bite the bullet, and he was responsible for entanglement with the main force of the Tang army, making it difficult for the main force of the Tang army to move south.

And let Na Gaohui really have the opportunity to unite the defenders of Najili City, Anshi City, and Jian'an City, and strive to wipe out all the soldiers and horses under the command of the governor of Natang State Yingzhou under Jian'an City.

Only by severely defeating the soldiers and horses of the Tang State can the morale of Goguryeo be restored. At the same time, the Tang State's conquest of Goguryeo this time does not have many troops.

As long as one finger can be cut off and Tang Guo understands Goguryeo's strength, Tang Guo will not dare to go deep alone, and can only do it step by step.

In that way, for Goguryeo, which occupies a favorable location, a protracted war is the most beneficial.

And when the forward of the army commanded by Gao Yanshou was less than five miles away from the camp of the Tang Kingdom, the forward general brought a piece of news that shocked him.

That is, after seeing the frequent appearance of Goguryeo's scouts, the Tang State Camp sent a large number of rangers to intercept and kill Goguryeo's scouts.

This is not over yet, the soldiers and horses of the Tang Dynasty stationed in the big camp actually started to withdraw from the big camp, and began to withdraw along the road to the opposite direction of Gao Yanshou's troops...

Such a move immediately aroused Gao Yanshou's suspicion, and immediately rushed to the forward.

But when he ran all the way surrounded by a crowd of cavalry, he finally arrived at the camp of the Tang army.

At this moment, the camp had been occupied by Goguryeo warriors, and Gao Yanshou looked at the chaotic and messy camp with a face full of astonishment.

Before he stayed here for too long, the scouts in front came again to report that there were no more than 10,000 Tang troops retreating, and most of them were infantry.

What's important is that they found something incredible on the way this Tang Guo soldier who was running in a hurry fled.

"Are you sure?!" Gao Yanshou's eyeballs immediately bulged, and he grabbed the subordinate who came back to report to him.

"I'm sure the general is sure that the extravagant car with incomparable wheel ratios fell sideways on the side of the road, and a lot of flags fell off, as well as that kind of exaggerated canopy..."

The leader of the detective cavalry asked his subordinates to put the flags and some miscellaneous decorations they had picked up on the ground. Jin Yanshou looked at those things, and his heart immediately became hot.

It's no wonder that the soldiers and horses of the Tang Dynasty had to withdraw as soon as they encountered their own forward army.

There is only one possibility, that is, the main force of the Tang Kingdom has already moved south, and the Great Tang Emperor will naturally sit in the rear.

Maybe he didn't expect that he would suddenly lead an army to appear here, and the emperor of the Tang Dynasty probably didn't have many soldiers around him.

That's why he fled away immediately, but he didn't expect that these treasures dropped on the way would be enough to reveal his identity.

Not only Gao Yanshou reacted, but the eyeballs of the Goguryeo generals beside him immediately turned red.

"Xu Sa, it's actually the emperor of the Tang Dynasty. It's just a stroke of luck for us to bump into a big fish."

"Nusa, the last general is willing to lead his troops and go after them first."

"Shut up, sir! Bring the map here." Gao Yanshou took a deep breath, controlled his emotions, and glanced at the ceremonial utensils used by the Emperor of the Tang Dynasty.

Soon, the map was unfolded in front of those Goguryeo generals and barbarian generals.

Gao Yanshou's gaze moved forward slowly along that road, while the general Noah beside him said in a low voice.

"Nusa, the direction they are evacuating now seems to want to retreat to Liaodong City."

Gao Yanshou narrowed his eyes~lightnovelpub.net~ and asked the striker again. "Dong Chun, how many troops does this Tang army have?"

"Xa, this Tang army has more than ten thousand soldiers and horses, most of them are infantry, and only a few cavalry."

Hearing this, Gao Yanshou smacked his mouth and glanced away.

"Dongchun, you immediately lead the cavalry of the headquarters to copy this road for the commander, and hurry up. You must be here to block Tang's retreat."

"Even if your soldiers and horses are dead, you must not take a step back, or you will come to see me."

"The general obeys orders." Dong Chun's heart trembled, and he quickly walked away after saluting to Gao Yanshou.

"Noah, you immediately lead the forwards to the commander to bite this Tang Jun and delay their speed. The commander will lead the main force to come."

With the issuance of military orders one by one, soon, the Goguryeo army, which originally wanted to delay the main force of the Tang army, was chasing after the retreating Tang soldiers like a pack of hungry wolves.
