The pressure on the defenders in the city was clearly greater.

However, the methods of the Grass Thistle Mountain Rebels are not limited to this.

They brought out the ballistas again.

The ballista fired arrows at a speed far faster than the fireballs thrown by the trebuchet.

In addition, the arrow is tied to a powder cartridge, and after it is ignited, it is a sharp weapon to urge life.

The foundation building monks of the state capital army could only block some of the ballista arrows, and the rest fell near the siege equipment, and then found the explosion, which blew the siege equipment to pieces, and the soldiers carrying the siege equipment also suffered heavy casualties.

Then the ballistas on the walls targeted the monks who built the foundation.

Ballista arrows burst into the air, forcing the foundation-building monks to be cautious.

The trebuchets who were no longer targeted were frantically harvesting their lives, and the soldiers who had transformed into cultivators had little room to resist in front of the big fireballs and boulders smashed by the trebuchets, even if they formed a defensive formation, they were also bombarded by the big fireballs and boulders, and the defensive shield was smashed to pieces, and the soldiers who condensed the defensive formation all flew upside down.

The war has entered a fever pitch.

The besieging side will always bear more casualties.

However, Wei Yuxiao's expression was only rational, without the slightest woman's kindness.

Envoy Li stood aside, equally without mercy, and even felt that this bloody scene made his heart a little excited.

When the eastern, western, and southern city walls were in full swing, in the direction of the northern city walls, special forces under the command of Dong Poison King began to act.

All of them were dressed in black clothes and black pants, black scarves and black hats, and their whole bodies were completely integrated into the night, digging tunnels in the trenches hundreds of meters outside the northern city wall.

At this time, the war was in full swing, and everyone's attention was attracted by the war, and the defenders of Dong Poison did not use Tingweng (an ancient tool buried in the ground to eavesdrop on the surrounding movements, which could be used to prevent the enemy from digging tunnels in the defense of the city).

In order to cooperate with this operation and interfere with the possible existence of Tingweng, Li Envoy asked people to dig tunnels in all directions of Changping County at the same time, and if there was Tingweng in the city, it would be difficult to distinguish which direction was digging.

In fact, the Grass Thistle Mountain Rebels have long known that the enemy army will dig tunnels at the northern city wall.

Originally, they waited for the enemy army to dig into the city, and then set fire to the enemy troops in the tunnels.

However, King Dong couldn't wait, so when the special forces dug under the city wall and did not cross the root of the wall into the city, he ordered the soldiers to dig up.

Eventually, the entire special forces appeared under the northern wall through the tunnels, and threw canisters filled with toxic smoke into the city.

Bang bang!

Jars cracked in the city one after another, and billowing poisonous smoke spread across the city walls.

Fortunately, Lu Pei arranged a large number of scarecrows on the city wall, reducing the number of defenders on the city wall, so that not many people were affected by the poisonous smoke.

At the same time, a small force that Lu Pei had already arranged involved the mechanism on the scarecrow, causing the scarecrow to fall uniformly.

Wearing the best gas masks in the city, this small unit took refuge in the dark chambers that had been prepared in the city walls once the mission was complete.

This is Lu Pei's caution, he understands that the enemy army sneaks into the northern city wall, whether he enters the city or not, he will definitely deal with the defenders on the city wall first, prepare an extra retreat for himself, and also open the city gate and let more enemy troops in.

Therefore, he was worried that if the scarecrow did not fall, it would make Dong Poison King's troops suspicious, and he missed the opportunity to give Dong Poison King a head-on blow or even kill the other party in the city, so he carefully arranged this small army.

But the enemy army began to attack from outside the city, which did not match the information from Wei Yuxiao, and it was still unexpected by Wu Liuer and others.

Lu Pei immediately sent a flag order to the small army, not to enter the dark room, but to hide directly under the battlements, waiting for the enemy army to come up the wall.

At the same time, he also arranged for his troops to secretly ascend the city wall, and this battle may have to be solved directly on the city wall.

Seeing that his trick had been successful, King Dong ordered the special forces to start climbing over the wall.

Iron claws with ropes were thrown by them, stuck on the walls, and climbed up the ropes.

The entire special force has already swallowed the antidote and will not be affected by the poisonous smoke.

However, the troops who arrived in the city were not so lucky, and the inferior gas masks they used were still effective against the smoke, but not all of them were capable of facing the smoke.

Some of the soldiers began to feel slightly dizzy, but in the current situation, they could not report their problems to the top, so they could only stubbornly go up, thinking that it was just smoke, and it was a big deal to go up to the city wall first, and then report to their superiors if they could evacuate later.

Unfortunately, this thought has left their lives on the brink of death.

When Dong Poison King's special troops climbed the city wall, the soldiers hiding under the battlements immediately jumped out to give them a head-on blow.

Before the soldiers of the special forces could reach the city walls, they had already fallen from the sky and turned into corpses.

Dong Poison King came to his senses at this time and fell into a trap.

So he did not hesitate to order the withdrawal, not caring at all about the soldiers who remained on the ropes.

He turned and ran, taking advantage of the darkness of the night, he quickly burrowed back into the tunnel, and then ordered the tunnel to be blocked, regardless of the subordinates who remained on the tunnel.

The soldiers who remained under the walls fled in a chaotic manner, showing their ugliness.

The soldiers on the rope slid down the rope quickly, and the soldiers below fell to the ground, and some were used as meat pads, and finally trampled to death at the feet of their own people.

The soldiers who had not yet climbed the rope tried to return to the tunnel, only to find that the tunnel entrance had collapsed, leaving only a deep pit in place, leaving them with no way to escape.

They had no choice but to run wild in the wilderness, but where could they escape the arrows shot from the walls.

Many people fell to the ground after being hit by an arrow, and those who were lucky could drag their injured bodies to continue to escape, and they could not stand up again after being hit by an arrow.

At this moment, the gates of the northern city opened.

The cavalry of the Grass Thistle Mountain Rebels poured out from the city gates, chasing down the soldiers who had fled from the desert.

Although this battle failed to catch the turtle in the urn, it also gave the enemy a counterattack ruthlessly, so that the enemy's dream of a night attack was completely shattered.

The victory belonged to the Grass Ji Mountain Righteous Army, and many of the special troops brought out by King Dong Poison died under the blades of the cavalry.

But this victory was also painful.

Many of the soldiers who had climbed the city wall to meet the enemy were either dead or crippled when they walked down the wall.

At this time, Lu Pei, who was in charge of the command, realized that what Dong Poison King threw was not smoke at all, but poison.

He regretted that he had taken the information for granted, thinking it was smoke and not treating it as deadly poisonous smoke.

It's a waste of being so cautious on weekdays, but in the end I still miscalculated.

Often walking by the river, there is always a time when there are wet shoes, this is the second time he has wet shoes, the last time was a failure under Tang Xiao's hands, and now he is working hard for Tang Xiao, but he has handed in such a result, how to explain to Tang Xiao!
