This is the first time, and it is also the first time that Xun Yu and others have felt how tragic the damage caused by the stones fired by the thunderbolt is, and how much psychological pressure is caused to them as the defenders of the city.

When attacking Yecheng, Qin Feng used a trebuchet to beat Li Tong and the Cao army at that time, Li Tong and the Cao army at that time were both dead, and the Cao army of Xu Du felt the power of the thunderbolt for the first time, and the soldiers were frightened crazy one by one, and many people were looking for safe hiding spots around the city wall, but there were people everywhere.

The stones fell on the outside of the city wall, the whole wall was shaking, the stones were smashed on the city wall, the exploded rubble flew everywhere, and many Cao soldiers were shot into large bags and small bags by the rubble, screaming again and again.

There are also many sergeants who were directly hit by big stones, and were smashed into meat and mud stones on the spot and continued to roll, causing continuous casualties, some were directly run over by big stones, some were crushed into meat cakes, and some were crushed hands and feet.

The rubble flying everywhere made Xun Yu and the others hide in the city tower and dare not come out, and the sergeants on the city wall hugged their heads directly, and their bodies were smashed by the rubble.

On the city wall, some of the battlements were hit by stones and collapsed on the spot.

With a "clang", a pot of boiling water was smashed, and the boiling water and iron pieces flew wildly, only making the surrounding sergeants scream.

Before the battle officially began, the defenders suffered considerable casualties.

Seeing that the stones had been smashed out in more than a dozen waves, Xu Shu ordered the siege equipment to set up crossbow arrows.

At the sound of the command, arm-thick crossbow arrows were shot out by the bed crossbows, and these crossbow arrows were powerful and fast, and they were easily nailed to the city walls, not to kill the enemy, but to be used by the siege soldiers as a way to climb the walls.

"Qi Qi military division, the crossbow bolt has been fired!" The sergeant of the siege equipment battalion came to report.

Xu Shu saw that the defenders on the city wall were still hiding and did not dare to take the lead, and immediately ordered: "The first wave of siege begins, set up wooden ladders and lay planks to build river bridges, and the cloud echelon will follow!" ”

The herald conveyed the order, and the drums and flags simultaneously conveyed the order to the siege to the soldiers in front.

"Rush—" Rows of sergeants roared forward in groups of four, all of whom were strong warriors, not only wearing thick bamboo armor, but also wearing shields on their chests.

After rushing into the range of bows and arrows, the defenders on the city wall stuck out their heads to look, and the guards immediately ordered the arrows to be released.

"Whoosh ······" One arrow after another was fired, most of them landed on the ground, a few hit the planks, and some of the arrows still hit the front sergeant, but they were blocked by shields and bamboo armor, and were not harmed.

These people rushed to the moat, begged the people in front to quickly squat on the ground and press the front of the wooden ladder to the ground, and the people behind quickly pushed the wooden ladder up, and the wooden ladder was erected, and then fell down and crossed the moat, and the planks were sent by the sergeant behind to lay on the wooden ladder piece by piece.

In an instant, the planks on the moat were half-laid by the Flame Sergeant.

Xun Yu and the others on the city wall were dumbfounded, laying a wooden bridge over the moat was so fast, these soldiers were definitely not ordinary soldiers, they cooperated so tightly, without long-term training, it was absolutely impossible to do this.

"Shoot them, shoot them, you can't let them lay the bridge, shoot them!"

Waves of arrows rained down from the walls, and despite the Flame Sergeants' well-trained and well-trained shields and other things to protect themselves, many of them were shot and fell.

When Xu Shu, who was in the distance, saw it, he ordered: "Two teams of sergeants with large shields went over to block the front to block the arrows for the sergeants who laid the wooden ladders and planks!" ”

The order was given, and soon two groups of sergeants rushed to the city wall with large shields, and these men stepped on wooden ladders to cross the moat and put the two large shields on top of each other, trying to block the arrows from the wall for the sergeants behind them.

In the past, the besieging army had to cross the moat, either by using the sergeant to pick up the soil to fill the moat, or by driving the people to use baskets to fill the moat, most siege battles were to drive the nearby people to pick up soil to fill the moat, the defenders were generally unwilling to waste arrows to shoot the people, and could only let the people fill the moat, so the moat could only play a role in delaying the siege time when many enemy troops attacked the city.

If it was a garrison general who received the news in advance, he might have thought of this, and implemented the policy of fortifying the walls and clearing the wilderness in advance, moving the people, grain, and livestock into the city, and even poisoning the water source, so that the besieging troops could not get anything useful, and they could not catch the people to work as meat shields.

When the Flame Army completely laid the plank bridge on the moat, the casualties paid could be said to be minimal, which made Xun Yu and the others on the city wall stunned, they had seen a lot of siege battles, and they had never seen any side of the army be able to solve the obstacle of the moat so easily and at a very small cost.

In the distance, Xu Shu waved his hand: "The cloud echelon and the sword and shield soldiers can go up, rush over in turn, and the connection must be done!" ”

"Rush—" Men in groups of two rushed towards the city wall with ladders, followed by a large number of sword and shield soldiers.

The sergeants with the big shields in front of them put the big shields in front of them, covering most of their heads and bodies, and turned around and shouted, "Follow me!" ”

These sergeants carrying the ladders followed behind the shields, and with the protection of these shields, the damage rate caused to them by the arrows shot down from the city was greatly reduced, although some people were inevitably shot in the legs and feet, and the blow was not fatal.

Rushing to the city wall, the big shield soldiers immediately put the big shield on top of their heads, and the city continued to shoot arrows, smashing down ten stones, and the big shield was smashed with a bang.

Bunkers were erected, and the sergeants below pulled the bottom outward, and the iron hook at the top of the ladder was hooked to the city wall.

"Rush—" The sword and shield soldiers rushed over with small shields and steel knives.

From this moment on, the siege battle officially began, some sergeants with a shield in one hand, a steel knife in their mouths, the other hand with their legs and feet kept climbing up, while some sergeants began to climb the thick crossbow arrows on the city wall, these crossbow arrows were like thick stakes, very strong, enough to bear the weight of a person.

As a result, the soldiers of the Flame Army climbed densely on the city wall like ants.

The Flame Army showed such elite combat quality at the beginning, which scared Xun Yu and the others, and they had never experienced a siege battle of this intensity, so they stuck their heads out and saw that the outer walls of the city wall were all densely packed with Flame Army climbing rapidly.

"Hurry up and release the arrow—" Xiahoudun issued a poignant command.

However, the Flame Army was not unprepared, how could it be possible to completely expose these climbing sergeants to danger, and the archers who followed rushed over in large numbers and fired arrows at the battlements at the head of the city.

"Ahh
