The loudness of the trumpets and the sound of the war drums can determine the size of the enemy's advance.

However, in order to prevent the opponent from cheating, the general in charge of the war will send lookouts and scouts to ascertain the opponent's strength before the war begins.

Kou Ji just deduced from the sound of the horn that Xiao Pidi was leading 80,000 Liao soldiers to attack the city.

However, Di Qing saw with his own eyes the 80,000 Liao soldiers pressing down in front of Yangguan Pass in a dark mass.

Eighty thousand Liao soldiers formed a neat military formation and advanced towards Yangguan step by step. They looked quite powerful.

Almost all the military strategies learned by the generals of the Liao Kingdom were derived from the Central Plains. Therefore, when the Liao soldiers set up military formations and attacked cities, they were very similar to the Song army.

The Forbidden Army officers on top of the city looked at the Liao soldiers outside the city, indifferent.

The Black Khan looked at the military formation outside the city, feeling a little frightened.

They were used to seeing swarms of sieges.

But I have never seen such a siege scene where the Liao soldiers maintained a neat military formation and advanced forward.

The Heihan people don't know whether the Liao soldiers who set up their military formations to attack the city are powerful or not.

But the neat military formation put up by the Liao soldiers looked really good, and it somewhat frightened the Black Khans on the city wall.

Di Qing stood behind the Black Khan. When he saw the Black Khan turning around frequently with fear in his eyes, he guessed that the Black Khan might have been frightened by the opponent's military formation.

"Bang the drum!"

Di Qing shouted loudly, and hundreds of large drums were beaten at the same time. The dull and heavy sound of the drums gave the Black Khan people some sense of security.

One drum is more than half.

The Forbidden Army soldiers beat their chests with the hilts of their swords, making a uniform sound of gold and iron clashing.

"Tiger!"

"Tiger!"

"Tiger!"

"..."

A high-pitched roar suddenly rang in the ears of the black man.

The roar gave off a fierce aura.

The Heihan people were shocked when they heard this.

The fear brought to them by the Liao soldiers was swept away in an instant.

Because they knew it, their slave masters sent a stronger army to stand behind them.

They will not lose this battle, and they will not necessarily die.

"oh!"

The Black Khan didn't know what his motives were, but after the soldiers of the imperial army finished shouting, they started shouting in confusion.

It seems that he is emboldening himself through roaring.

It also seemed to be responding to the shouts of the Forbidden Army soldiers and expressing their loyalty to the slave owners.

When Di Qing saw this, he couldn't laugh or cry.

The momentum that the Forbidden Army soldiers had just gathered was completely destroyed by them in an instant.

However, Di Qing could see what the Black Khans were thinking, so he couldn't blame them.

Kou Ji and Li Di didn't know when they reached the top of the city and witnessed with their own eyes the shouts of the Forbidden Army soldiers and the random shouts of the Black Khans.

Li Di frowned as he listened to the shouting of those black men, and commented in a low voice, "A bunch of rabble..."

Kou Ji did not comment on the black people, but walked towards Di Qing.

Di Qing saw Kou Ji and Li Di and hurried forward to greet them.

"Brother... Mr. Li..."

Kou Ji didn't wait for Di Qing to finish the ceremony, then waved his hand and said: "You don't have to worry about us two, just pretend that we have never appeared."

Speaking of this, Kou Ji asked: "When did you send the Tiger Character Army to the Yongxing Army?"

If Kou Ji remembers correctly, using tiger as a nickname and shouting the word tiger are the favorite things of the tiger-character army.

Di Qing smiled and said: "I have some soldiers under my command who have been following me since the reorganization of the Tiger Character Army. When they reorganize and train their troops, they like to use the tactics of the Tiger Character Army.

Over time, it became like this.”

Kou Ji nodded and said nothing more.

When the Liao soldiers officially launched their attack on Yangguan, Kou Ji and Li Di left the city wall.

The two of them ran to the top of the city and wandered around, doing it on the spur of the moment.

In order not to interfere with Di Qing's command of the battle, the two of them wisely climbed down the city wall when the battle started.

From beginning to end, neither of them gave any instructions on the military affairs on the city wall.

This was unimaginable before.

In the past, those who monitored the army or the important ministers who were in charge of the army always had to show off themselves before going to war.

Either he was dictating the military affairs, or he was pulling a few people out to kill the sacrificial flag, in order to show off his authority to the soldiers.

When Kou Ji and Li Di descended from the city, the arrows of the Liao soldiers floated up to Yangguan.

The reason why the arrow is used is because after the arrow is shot, it is affected by the wind and the accuracy is not so good.

The arrows fired by the Liao soldiers were dense and numerous.

The Black Khans lay on the crenels, holding up their shields to resist the arrows of the Liao soldiers.

Arrows came down like rain, and before long, many arrows were inserted into the shields in the hands of the Black Khan soldiers.

Seeing this, Di Qing frowned slightly and prepared to order the Black Khans to fight back.

But before he could say anything, the Heihan man took advantage of the opportunity for the Liao soldiers to bend their bows and set up arrows to fire the second round. He controlled a hundred tigers to run together, used crossbows and heavy crossbows, and shot at the Liao soldiers.

Di Qing was slightly stunned when he saw this.

After thinking about it for a while, I understood what the Black Khans were doing.

Although the Black Khans are now reduced to prisoners of war and slaves, they were born as soldiers and have some instincts as soldiers.

There was also rain of arrows when attacking the city in the west.

Therefore, the Black Khan people knew that when the arrows rained down, they should avoid their sharp edges.

I also know that after the sharp edge has passed, I need to find the right opportunity to counterattack.

The Black Khans and Liao soldiers used bows, crossbows, crossbows and other equipment to kill each other.

The cry of killing instantly filled the entire Yangguan.

The Liao soldiers carried their crossbows and arrows to the top of the city, cut off the suspension bridge, and began to attack the city.

All kinds of siege equipment were used on Yangguan Pass.

The Liao soldiers pushed the siege chisel and beat hard on the city gate.

The city gate was smashed into wooden pits one after another.

At the gate of the city is a stone wall built with stones. The stone wall is estimated to be four feet thick.

It was simply impossible for the Liao soldiers to attack the city and break open the gate of Yangguan.

Kou Ji had already decided that he would spend a month or two with the troops of the Black Khan Dynasty and the Liao soldiers, and wait for the Liao Emperor Yelu Longxu to lead the Liao soldiers south, and wait for Qingtang to send troops before he would counterattack.

After Di Qing learned about this, he decisively ordered people to dig rocks to block the door.

Anyway, we have to stay in Yangguan and not go out to fight back. If the door is blocked, it will not have any impact on the war.

The Liao soldiers did not know that the Yangguan gate they were attacking had long been blocked by a stone wall, and they were still hammering hard.

Other Liao soldiers carried ladders and pushed siege vehicles, and climbed up to the top of the city.

Under the guidance of Song Bing, the Black Khans pushed rolling logs, stones, gold juice and other objects down the city.

Because there are enough rolling logs, stones, and gold juice.

So Black Khan people don’t have to save.

A huge number of rolling logs, stones, and gold juice descended on the city, posing a huge obstacle to the Liao soldiers' attack on the city.

The Liao soldiers launched four or five charges in a row, but failed to reach the top of the city.

Xiao Pidi had been following the battle from behind. After seeing no artillery or muskets appearing, he frowned.

Xiao Pidi recruited a private soldier and ordered the private soldier to investigate the situation.

After investigating for a long time, the soldiers came back to report.

"General, the soldiers at the front say that the enemies against them are all Black Khans. So far, no trace of Song soldiers has been seen."

After Xiao Pidi listened to the report of his soldiers, he sat on the horse and froze for a long time.
