The order of the king of Donghu was issued.

Immediately, 10,000 Mongolian cavalry on horseback were assembled after sunset.

At the same time, on the Great Wall, the soldiers and civilians defending were also exhausted.

Almost all the soldiers and civilians were already exhausted and collapsed.

In the continuous fighting, they killed at least forty or fifty thousand Donghu people.

However, this also caused them to pay thousands of dead and wounded.

Moreover, the rest of the people and horses, how many people and horses have their bodies, are also wounded.

And most importantly.

They're so tired right now.

The Donghu people continued to attack.

So that the current city wall, guarding them, can't wait to fall down directly and sleep with him for three days and three nights.

When night falls.

There are quite a few people, even directly, who have fallen asleep.

But at this time.

Zhang Luo, the county guard, was wearing a copper armor and led a team of mighty soldiers to the city wall, inspecting the defense, and encouraging the guards who were guarding.

The women and children in the rear carried the prepared meals to the city wall and distributed them to the soldiers.

It was at this time.

Suddenly, there was a sound of horses' hooves in the air.

Immediately, Zhang Luo sensed that something was wrong.

He realized.

It's the soldiers of King Donghu, and they've been killed!

For a while, Zhang Luo immediately ordered to defend.

At the same time, in the dark.

Sections of the city wall.

Along the gentle slope formed by the accumulation of corpses, the Donghu cavalry rushed directly to the Great Wall, and then began to fight in the pile of people.

What I saw was Zhang Luo's shock for a while.

Slap his thigh again.

Secretly regretted it.

He should have sent people to pour fire oil into the pile of corpses outside the Great Wall.

Burn the corpses to the ground.

If it weren't for this, it wouldn't have allowed the Donghu people to take advantage of this opportunity to rush to the city wall.

Just when Zhang Luo regretted it to the extreme.

In the distance, King Donghu laughed.

"It seems that we will soon be able to break through the Yuyang County of the Qin people!"

"The warriors of Donghu, the fields and villages of the Qin people, the people of Lilu, and the women of the Qin people are opening their arms to us and killing me!"

"Kill!"

Thinking of the Qin people within the Great Wall, who could be plundered.

For a time, the Hun soldiers under the command of King Donghu.

Under the fortified city for a long time, the soldiers who had been in decline suddenly improved a lot.

The Great Wall defense line is precarious!

"The county guard, I can't hold it!"

"County guard, what should I do?"

"County guard, why don't we shrink the defense line and let these Donghu people into the Kou, let's stick to Yuyang County, anyway, the people nearby have already been evacuated, and the reinforcements led by the Nineteenth Prince will arrive soon, as long as we hold Yuyang County, the Donghu people will at most scourge the crops in the field!"

"That's right, the county guard, if you persist now, our manpower will be killed by the Donghu people sooner or later, and at that time, it will be said that it is the Great Wall, and Yuyang County will not be able to keep it!"

On the side, another general's voice sounded.

He was telling the truth.

At the moment, the hand-to-hand battle was encountered.

Great Qin's firearms and Great Qin's bombs are no longer useful.

And the Donghu people had a numerical advantage.

Moreover, they rushed under the Great Wall on horseback along the gentle slope formed by the corpses.

In such a situation.

Defend the Great Wall.

Sooner or later, all the staff will die in battle, so it is better to retreat to the county town of Yuyang County where the fortifications have been completed.

Anyway, the people nearby have already gathered in the county town.

Don't worry about safety at all!

As for the people of the hinterland?

Then don't worry!

Because, everyone knows that the army under the command of Win Changsheng is already very close to here, but it is only a few dozen miles, and it will be able to reach it tomorrow morning!

Hearing this, Zhang Luo gritted his teeth, and then said.

"That's all I can do, but when we retreat, I'll have to use a plan!"

As he spoke, Zhang Luo ordered.

"Pour all the fire oil under the Great Wall under the control of our army, and then, send a few dead soldiers, prepare to set fire, and leave all the bombs, as long as the fire oil is ignited, the bombs will go off, and at that time, the Donghu people will inevitably suffer heavy losses in the fire oil and bombs!"

"The county guard is wise!"

When the generals on the side heard this, their eyes lit up and they praised and said.

"Stop talking nonsense, hurry down and prepare!"

Zhang Luo urged impatiently.

In his opinion, now is not the time for his subordinates to slap him on the back.

Instead, stick to the Great Wall.

When defending against the enemy.

Who cares about listening to people's sycophants?

When the Qin army was arranging a retreat.

King Donghu, who was located in the distance, finally flashed with joy in his bloodshot eyes.

I only saw that the king of Donghu was retreating from the Qin army.

Wielding a scimitar, he urged his cavalry to occupy the entire section of the Great Wall as soon as possible.

Then, fight your way inside the Great Wall.

Squadrons of Donghu cavalry.

Poured into the Great Wall.

The Great Wall is very wide.

It can accommodate several horses side by side.

At this moment, when the Great Wall is crowded.

Hiding the dead in the pile of dead people.

But immediately, he took out the fire fold from his arms.

Immediately, he suddenly turned over and jumped off the Great Wall, but the fire fold in his hand was thrown on the ground of the Great Wall, and then, after falling heavily to the ground.

The soldier, whose leg was not broken, quickly took a step and fled to the county town in the distance.

And when they ran back to the county town for their lives.

Above the Great Wall.

With the fire fold fell to the ground.

The spilled oil.

It was ignited in an instant.

For a while, a fire burned in the air!

After the fire burned.

The Donghu soldiers above, the leather robes they were wearing, were also instantly ignited.

The horses, too, were scorched by the fire on the ground, and began to neigh violently, and rushed in all directions above the Great Wall.

At the same time, bombs were left on the ground.

Also at this moment, it is ignited.

Immediately, there was a booming bang.

Looking at the Donghu King in the distance, his heart was broken.

The reason is simple.

On the Great Wall at this time.

However, more than 10,000 Donghu cavalry are crowded!

And for now.

More than 10,000 Donghu cavalry.

and all of them were buried in the flames.

How can he not be angry?

And, most importantly.

above the burning of the oil.

On the Great Wall near here, the fire oil is combined with the corpse, and the flames that burn out are really not small.

The scorching heat wave can be felt far away.

They simply can't get any closer to the Great Wall.

In other words, at the moment, he can't send troops to the Great Wall, so he can only stand in vain on the grassland north of the Great Wall, look at the burning Great Wall in the distance, and curse one after another!
