Tuyuhun's first siege of the city was defeated by the wolf's tooth slap, and thousands of daredevils dropped nearly 100 corpses and retreated to the military formation.

However, Murong Yong was not discouraged, but arranged for the second batch of soldiers to prepare.

Moments later, more than two hundred Turkic archers appeared in the Tuyuhun siege team.

The siege began, and it seemed no different from before.

But when the wolf's tooth swatter reappeared, the Turkic archers bent their bows and arrows.

They didn't shoot the defenders, but the ropes tied to the wolf's fangs.

You don't have to shoot them all, you only need to hit one, and the square wooden board will lose its balance.

"Kill!!"

The selected Turkic archers, there is no doubt about the accuracy, when the wolf's tooth slap tilted, the soldier at the front of the ladder jumped up with a loud shout, regardless of the feathered arrows shot down from above, clung to the wolf's tooth slap, and dragged it to the city with all his strength.

The soldiers in the back did the same, some clinging to the wolf's fangs and pulling the legs of the allies above in order to drag the damn thing out of the wall.

How could the sword and shield soldiers on the city wall have such a strong force to pull so many enemy soldiers, and seeing that they were about to be dragged off the city wall with the wolf tooth pat, they quickly let go of their hands.

Boom!

There were several loud bangs, and the wolf teeth on the head of the city fell one after another.

The Tuyuhun soldiers who were lying on it patted their butts with good luck and got up quickly, and those who were unlucky either fell to death or were killed by arrows.

"Kill!"

There was another shout, and the Tuyuhun siege team rushed to the ladder, and the Turkic iron cavalry as cover was dispatched again, raining down pieces of arrows on the city.

The sword and shield soldiers were no less impressive, with war shields on their heads, spears and arrows, killing the enemy outside the city walls one after another.

The fight was fierce.

Sitting firmly under the city gate building, Yang Shuang listened to the casualties from everywhere without impatience, and turned his head to look at Shi Da and Lu Xiaobu.

"When the third wave of siege is over, change the defense!"

"Understood, big brother!" The two turned to leave.

Yang Shuang thought that the other party would attack the city at noon, but he did not arrange to eat in advance.

It's not arrogance, but enough confidence in Yangguan's defense.

The siege was not a continuous oppression, and all the troops rushed up in one go.

Rather, it is to probe, probe, and probe, and then carry out a general attack when it is perceived that the defender is not physically strong, or that the troops are insufficient.

When more than half of the second group of siege troops were killed and wounded, there was a sound of gold in the distance.

The Tuyuhun soldiers, who were blocked in the middle of the ladder, retreated in an orderly manner with large shields.

A rain of arrows rained down on the city, taking away several unlucky ghosts who were seriously injured and had difficulty moving.

After two accumulations, less than 30 of them were wounded and disabled, and 700 corpses were left behind by the enemy.

The results were counted, but Yang Shuang was not very satisfied.

There are no skills in this battle, and there are no various anti-heaven technologies, but as the strongest pass on your side, the casualty ratio of one to thirty is really a bit high.

You must know that the sword and shield soldiers are all fused with the soul of the soldier, and in terms of combat power alone, they will absolutely crush the opponent.

"Kill!"

Outside the pass, the shouting of killing sounded again, and the third group of siege teams rushed in, leaving no time for Yang Shuang to think about it at all.

After the first two attritions, the ladder was seriously damaged, so in this siege, the opponent once again added ten newly made wooden shelves.

It is still the Turkic long-range suppression, the shooters below are covering, and the Tuyuhun soldiers are the main attackers.

The two sides are deadlocked, and the time has been moved to the afternoon.

However, it didn't take long for Murong Yong, who was on horseback and staring at the battlefield, to suddenly straighten up.

"Up?!"

Ah Bo and Murong Fuyun beside him shook their heads, and immediately followed their fingers to look ahead.

The third group of siege troops numbered as many as 3,000 men, even if they were distributed around twenty ladders, which seemed quite large.

Originally, it was like a dumpling falling down their own soldiers, but at this time, there were already several people stuck in the battlement.

Another moment passed, and the soldier stuck in the battlement had already stepped into the wall on one leg!

"Up!"

Anyone will take a good opportunity!

Therefore, Murong Yong did not hesitate to wave the flag and launch a general attack with the 20,000 soldiers and horses behind him.

"Second brother think twice!" Murong Fuyun couldn't stop it, and with a worried face, he left behind five thousand soldiers and horses under his command.

Although Apo was expressionless, he quietly conveyed the order to the back, ready to attack the city at any time!

For Yang Shuang, Yangguan is just a pass, but for the Turks and Tuyuhun, it is a strategic position.

Tuyuhun got it, looking north at Dunhuang!

If Apo gets it, he will be able to control the Silk Road from Xiliang to the Western Regions, and he can also cut off the connection between the Great Sui and the Western Regions!

"The Sui army has no strength, rushed to the city wall, rewarded ten catties of refined salt, and ten beautiful concubines!" Murong Yong had no doubts about the weakness of the Sui army.

It is just a small fortress at the border pass, even if the garrison is mobilized, judging from the current situation of the Sui army, it is impossible to exceed 3,000.

What's more, Yang Shuang fled in a hurry, and his own side chased even faster, and the Yangguan defenders didn't have much time to deploy fortifications at all.

Besides, after two degrees of attrition, he also figured out that the defensive strength of Yangguan was nothing more than sword and shield soldiers and archers.

"Kill !!"

Seeing the army rushing behind him, the soldiers on the ladder were immediately excited, shields and guns blocked, and dozens of people climbed the city wall.

The flags that were originally evenly distributed on both sides of the wall battlement were also scattered at this moment.

Murong Yongfei dismounted, stood under the city wall and urged the soldiers to continue to rush upward.

The people who went up were first half a hundred, then hundreds, and then more than a thousand!

"Up!"

Murong Yong was very excited, he broke the border pass of the Sui army in one day, and he thought that he would definitely become famous after this battle!

At this time, the besieging soldiers no longer needed shields, and all of them held their weapons in one hand and rushed up the ladder with the other.

When the more than 3,000 people who were besieging the city all climbed the city wall, Murong Yong thought that he should almost rush into the pass!

Otherwise, how could the small city wall fit so many people?

Thinking of this, he took a few steps and stepped up the ladder to the battlement.

"Shhh

Seeing the above scene clearly, Murong gasped.

What a wide wall!

Compared with the two or three meters wide city walls in Longxi and the surrounding areas of Wuwei County, the Yangguan city wall is comparable to the official road in the Central Plains, and it is more than ten meters wide!

No matter how you look at it, it looks like two walls overlapping in parallel!

Parallel coincidence ?!

Why did they build two walls?

Thinking together, Murong Yong was vigilant.

At this time, one south and one north, under the feet of the Tuyuhun soldiers who were in a stalemate with the Sui army, there was a tooth-sore metal twisting sound, and then, a deafening earth-shattering sound spread throughout the battlefield.

Gala la boom!

In Yangguan, on both sides of the city wall, two teams composed of nearly a hundred war horses, commanded by Shi Da and Lu Xiaobu, pulled two huge gears.

The gears are made of wood as a whole, wrapped in heavy iron, and the evenly dense canine teeth clench on countless pulley sets.

These pulleys are located within the northern wall, but to the south are large horizontal wooden pillars.

If anyone climbs into the southern wall through these wooden pillars, they will be horrified to find that they are holding the passage of the southern wall.

And below the passage, there are densely packed, countless spears glowing with cold light!

As the war horse pulled the gears hard, driving the pulley block, the horizontal wooden column rolled, and the end of the "T" shape suddenly tilted.

In Murong Yong's eyes, the passage of the city wall close to him was slowly cracking!

When he saw the cold glow below under the scorching sun through the gap, his eyes darkened, and he fell down.
