The rumbling sound of killing pierced through the darkness and penetrated into the ears of Cai Jun at the head of the city.

It blends with the boulders that hit the city from time to time, and the sound of spears merges, like a whistling autumn wind, with a chill to the bone!

Under the city, in the Yan cavalry, there are strong soldiers who turn over and jump off the war horse, carry the head knife on their backs, grasp the crossbow in their hands, illuminate the ground with torches at the head of the city, and with the help of the torches swaying light, they move forward and move under the city wall.

In fright, Wang Hongyan broke out in cold sweat on his forehead, clutched the hilt of his sword tightly, and his head popped out, and then the torches of the city wall gasped for fire, and his eyes paid attention to the city wall.

When the Yan army was attacking the city and suppressing the Cai army, when the counterattack at the east gate was lax, a large number of Yan troops took the opportunity to approach!

Looking at it, Wang Hongyan was puzzled, the Yan army moved forward, there were neither siege vehicles nor ladders, how to attack the city.

rushed forward without any scruples, is it killing yourself?

Boom!

In contemplation, a boulder fell from the air, which happened to hit the battlement where Wang Hongyan was hiding, and the battlement vibrated violently, shaking Wang Hongyan's scalp numb.

couldn't help but panic, couldn't help but lean on the inside of the city wall, and his body took the initiative to shrink down along the inside of the city wall.

"What the hell are these bastards going to do?" Wang Hongyan leaned against the city wall, panting, and couldn't help but scold!

Under the city wall, a large number of Yan troops under the cover of siege equipment did not spend much effort, and easily reached the bottom of the east gate!

They quickly grabbed the spear that pierced into the wall, and quickly climbed along the wall towards the city!

For a while, there seemed to be countless geckos on the head of the city, shuttling quickly!

The Yan army is well-trained, physically strong, and has a four-zhang high city wall, when there is no external force to stop it, for them, it is like a gecko strolling, it is easy!

In the corridor of the city wall, Wang Hongyan was panicked in his heart, and he couldn't guess what Yan Jun meant, and his heart became more and more panicked!

Frightened and hesitant, he sent the defenders around him to get up and monitor the movements of the Yan army.

Two defenders in a row, who had just shown their heads, were shot through by inexplicable cold arrows under the city wall, killed on the spot, and fell off the city!

The defenders were inexplicably shot by cold arrows, which deepened Wang Hongyan's sense of crisis more and more, and he couldn't guess where the cold arrows came from when Yan Jun was six or seven hundred steps away!

In contemplation, Wang Hongyan only felt that the firelight in front of him was moving, and he didn't have time to think, and the torch inserted at the head of the city was knocked to the ground and splashed a little spark on the ground.

"Kill!"

The sparks in the aisle had not yet dispersed, and Wang Hongyan suddenly heard a shout of killing in his ears!

The voice came out, and a black-armored Yan soldier jumped into the city wall from the battlement,

The moment the soles of his feet landed, the armor all over his body made a crisp sound, and the Yan army was a fine soldier, holding a crossbow in his hand, shooting the enemies who were approaching from all sides.

Pull out the ring head knife and protect yourself!

One!

Two!

Three!

…….

In the blink of an eye, in the corridor of the city wall, dozens of Yan soldiers wearing iron armor appeared, quickly gathering on the city wall, and the number was increasing!

For a while, in the corridor of the city wall, there was a mess, although the number of Yan troops was small, they were still fierce and fierce, and they fought quickly to create opportunities for the follow-up arrival of the Yan army.

Wang Hongyan witnessed the Yan army appear inside the city wall, although he couldn't guess how the Yan army entered the city.

But it is very clear that when the Yan army enters the city, the situation will become worse and worse!

Hurriedly grabbed the short sword and shouted to the Cai army on all sides: "Hurry up, clear the defenders at the head of the city!" ”

A few days ago, he patted his chest and assured Cao Rong that the city of Mocheng was thick and the city could be defended by his army for two or three months.

Now it is only five or six days from that day, and he was attacked by the Yan army, if the emperor knew about it, he would be beheaded immediately to show the public.

The Cai army defending the city was also panicked, the iron-clad Yan army was like a heavenly soldier descending on the city wall, quickly hugging the group, when the troops were dealing with the weak, the Yan army united with each other, relying on the advantage of the crossbow, clearing the surrounding area close to the Cai army!

In addition, a steady stream of Yan troops, along the spear at the head of the city, climbed to the head of the city, and constantly expanded their advantages.

Cai Jun suffered a change, cowered and surrounded him, and strangled a few Yan troops!

"Kill!"

"Kill!"

Fan Changming personally led nearly a hundred Yan troops, and when he appeared on the city wall, he suddenly jumped down from the wall battlement, and a roar came out of his mouth.

When he landed, he drew out the ring head knife and slashed a approaching Cai Jun, the blade fell to the ground, and Cai Jun died tragically on the spot!

The momentum of the Yan army was like a rainbow and unstoppable, Wang Hongyan fought against the Yan army for the first time and was deeply shocked.

Don't dare to delay a little, hurriedly gather the defenders on all sides, quickly encircle and suppress the Yan army, and strive to quickly strangle the other party when the number of Yan troops is scarce!

At this moment, Lin Dongsheng led 10,000 Yan troops to stay under the city wall, in addition to sending siege vehicles to hit the city gate, he ordered the remaining troops to quickly approach the east gate of Mocheng, and with the rain of crossbow arrows, shoot the Cai army from the north gate, and reduce the pressure of Fan Changming and the Yan army that continued to climb over the city wall as much as possible!

Almost at the same time, the West Gate of Mocheng, Hou Yan Xu, and Zhang Guodong led 20,000 troops, adopting the same tactics as the Yan army of Ximen, and also quickly climbed the city wall.

Inside the corridor of the city wall, the battle is in full swing!

The north gate of Mocheng!

Hou Mingfeng, Zhang Yansong led 10,000 iron horsemen, standing quietly a mile away from the city!

With the light illuminated by the torches at the head of the city, Hou Mingfeng and Zhang Yansong could vaguely witness the changes of Cai's army within the city wall.

In addition, there are Yan army spies close to the north gate, and the defense of the Cai army at the north gate has changed, and it has been transmitted back in a steady stream.

In Hou Mingfeng's deployment, no matter how fierce and miserable the battle is at the east gate and west gate of Mocheng!

The attack at the north gate is the core of Hou Mingfeng's deployment!

When the spies informed Hou Mingfeng, at the east and west gates, Fan Changming, Lin Dongsheng, Hou Yanxu, and Zhang Guodong led the Yan army to climb the city wall.

Cai Jun, who was stationed at the north gate, carried defensive equipment and quickly headed towards the east and west city gates.

At present, the defense of the north gate of Mocheng is the most empty, and the number of defenders is far lower than when the city was attacked three days ago.

Hou Mingfeng judged the situation and decided to send troops to attack the north gate!

The ring-headed knife was slowly drawn from its scabbard, making a squeaking sound, as if the killing god was roaring!

The knife was unsheathed, Hou Mingfeng quickly raised the ring head knife, exhaled a long breath, and suddenly shouted: "The whole army is attacking!" ”

"Yes!" Waiting for the swallow to ride, when he heard the order, he let out a deafening roar from his mouth.

Standing swallow ride, act fast!

However, the Yan cavalry of this 10,000-strong army, except for carrying two siege vehicles, did not carry any extra siege equipment!

However, dozens of Yan soldiers in the forward were holding wood and carrying fire oil.

These people, when the army was advancing, set out in advance, with the help of the dim lights at the head of the city, and quickly groped at the north gate of Mocheng when the attention of the defenders at the head of the city was diverted.

Quickly put the timber under the city gate, put oil on it, and the whole army quickly set it on fire.

Whew, the fire ignited, and soon the smoke billowed from the north gate, and the flames burned rapidly.

At the head of the north gate, Li Anheng, the deputy general of Cai Jun, smelled the smoke for the first time when the billowing smoke rose, and when he stretched out his head to look under the city, he suddenly encountered a messy rain of arrows!

In a panic, he hurriedly waved his short sword, avoided the rain of arrows, retracted his head, and couldn't help but be shocked into a cold sweat.

At this time, in the chaos of the city, I don't know who suddenly shouted: "Enemy attack, enemy attack!" ”

The enemy attacked, Li Anheng's thoughts were completely clear, and he suddenly panicked, and hurriedly ordered the defenders to fight!

Recently, the Yan army has attacked continuously, but they have never approached the city wall, let alone dare to light a fire under the city wall.

Not long ago, the East and West City Gates were fiercely attacked by the Yan army, and a large number of defenders of the North Gate, which should have been impregnable, were mobilized to the East and West City Gates, making the defense of the North Gate much lax.

Now, a large number of Yan troops appeared, and there was a fire under the city gate, Li Anheng realized that the north gate could not help but be attacked by the enemy, and the Yan army also planned to burn the city gate, taking advantage of the lax defense of the north gate to kill in the city!

Suddenly, Li Anheng only felt that the pressure on his shoulders was very high.

It seems that Cai Guo's life and death are all entrusted to his shoulders.

However, the North Gate also has its own advantages, in order to hold the Mocheng, resist the Yan army at the North Gate, and wait for the arrival of Wu Yue reinforcements, the emperor ordered the soldiers to defend the city and build the defense of the Mocheng City like an iron bucket.

Because the North Gate has been attacked by the Yan Army many times before, the North Gate has become the top priority of the defense of Mocheng!

Although a large number of defenders were mobilized and a large number of bed crossbows were dismantled and transported to the east and west gates, hundreds of bed crossbows were still erected in the corridor of the north gate city wall, equipped with boiling water, bundles of arrows, and ready to attack the defenders.

Hearing of the enemy attack, Li Anheng hurriedly ordered Cai Jun to fight, and in a panic, Cai Jun hurriedly grabbed the longbow and arrows, stood at the head of the city, looked around, and searched for the traces of the Yan army!

In addition, many defenders, quickly gathered, ignoring the billowing smoke from under the city gate, regardless of the Yan army in rows of arrows and fire, risking their lives, the boiling water prepared by the city wall in advance, quickly poured down from the city wall.

It's a pity that the firewood with fire oil added to it, once it is ignited, the fire is very large, and the Cai Jun above the city wall does not dare to approach the center of the city gate at all.

Otherwise, the flames will burn, and an overwhelming heat wave will rush in, which will quickly force people to retreat.
