The gradual contouring of the apparatus caused the defenders inside the castle to panic, and the long wooden arms revealed its trebuchet nature.

And this trebuchet is different from the trebuchet that was common in siege before, and it looks much more complicated than that trebuchet.

In fact, it was true, that the trebuchet had been designed by William over the course of four years, using his measmerical knowledge of physics from his previous life.

Of course, it was impossible to spend four years designing such a thing, and through desperate recollection, he finally came up with the design drawings of the trebuchet and the waterwheel, and planned the basic construction of canals and roads that would increase food production on a large scale.

The trebuchet is based on the design of the return cannon in the previous life, and uses torque to achieve the use of stone throwing, so it seems that the structure is complicated.

Moreover, the number of such trebuchets is not small, and this expedition to William brought out all the trebuchets in the territory, a full eighty.

Eighty trebuchets that can shoot powerful stones into castles or city walls without stopping.

The trebuchet may not give much advantage to the enemy, but it must be said that this weapon is capable of inflicting an unparalleled blow on the enemy's period.

If you are faced with this kind of fear for a long time, and you don't know when you will be hit by a stone and die, it is easy to cause a mental breakdown.

It is also normal for morale to collapse at that time.

Eighty trebuchets were formed in two teams, each lined up with four chambers, and were preparing for launch.

William had tested that the effective range of the trebuchet was about three kilometers, so it was completely free from the threat of enemy archers.

Looking at the defenders on the city walls, who had become scarce at the sight of the arrival of trebuchets, William gave the order.

"Reload!"

This round was just a test shot, and they placed rocks bigger than a human head in them.

Since William also applied gear technology to trebuchets, the operation of trebuchets was very simple, and there was no need for more than a dozen people to operate them at the same time.

As long as two people, you can rely on gear technology to manipulate this trebuchet well, from which it can be seen that technology is the first force.

"Launch!"

William drew his sword and gave the order for the trebuchet to fire.

"Whoosh!"

There was a sound of arrows breaking through the air, and stones larger than a human head were blasted away from the walls of the net under the impetus of the trebuchet.

"Bang bang!"

There was a collision sound, and there were not many stones that really hit the city wall, only a dozen, and this was just the first round of test firing.

The slingers would look for a firing point during the test shots, then lock on to an angle where they could hit the enemy's walls, and shoot from that angle all the time.

After remembering the position and angle, even the shot after the reset is much more accurate.

Only one stone hit the top of the enemy's walls, causing them about four or five casualties.

Despite the fact that the number of casualties is small, the deterrent they create far exceeds that of other weapons.

Just imagine the terrifying experience of a dense body of stones whistling over your head, and you don't know when the stones will fall on your head.

"Reload, prepare a round of tanks!"

Following William's orders, the soldiers placed a jar of refined oil from a clay pot on the robotic arm, lit the oil on the top of the tank, and began to aim in the direction of the enemy.

"Launch!"

There was a round of fire, and a full ninety oil canisters with the light of fire flew and the enemy's walls roared away.

Many oil canisters exploded on the enemy's walls in this way, and the stone walls burned weakly, but even so, there were still more than two dozen oil canisters that smashed accurately into the place where the enemy stood.

The oil in the tank burst open, and a small deflagration began under the ignition of the flames, and burned along with the oil to the entire city wall.

This round of projection caused more than 200 casualties to the enemy, and although there were not many armed infantry inside, only a dozen or so, the deterrent and morale blow to the enemy was incomparably huge.

In this way, within a few days, William carried out hundreds of rounds of bombardment of Issamdenburg, and even several trebuchets collapsed.

The Earl of Cansville stood at the top of the main castle, watching the bombardment of his own army outside the castle, in fact, he was also a little anxious.

In the past few days, the bombardment has caused more than 800 casualties among his men, including dozens of trained armed infantrymen.

It also caused great damage to the morale of the soldiers, and at this time the castle was full of panic, and rumors spread in the castle.

"Do you have an order?"

In a dark room in Issamdenburg, a beautiful woman dressed as a maid looked at a man with a mask and asked.

"Yes, I came to bring you an order from an adult!"

As he spoke, the man pulled out what resembled a letter from inside his clothes.

The woman took it without thinking, looked at the contents inside, couldn't help frowning, and said, "This task is too difficult!" ”

"Does it have to be done?"

"Yes!" The man with the mask said firmly, with a frenzy in his eyes: "You must know, Ariel, the Earl has led the army beyond Issamdenburg, and we must do our part for the great Earl, do you understand?" ”

As he spoke, the man's tone became more and more agitated, and it was clear that he was one of William's diehards.

After hearing this, the woman was obviously impatient, and said: "I know, I know, I really don't know why you people in Denlenburg are so fanatical about this Earl William, I admit that he is very good, but not so!" ”

"Enough!" The man scolded all his life, obviously very dissatisfied with the attitude of the woman, and said: "Lord Earl is the pillar of all of us, and I will not allow you to say that about him!" ”

The woman looked helpless when she heard this, but she was used to this situation, so she could only say helplessly: "Okay, okay, I will go and serve the world's greatest, wise, merciful, and heroic Earl William now!" ”

At this time, William issued an order to Urimu.

He looked at the Hulimu in front of him and said, "Hulimu, you take your light cavalry and my light cavalry to plunder together, as my light cavalry commander, I hope you can implement the three-light policy!" ”

He laughed, he was also very fond of this kind of errand, and after agreeing, he took seven hundred light cavalry and left the camp with the sound of light and crisp horses' hooves.

"Is it really good for us to do this?"

Norwen asked with some hesitation.

"It doesn't matter, if the enemy really cares, they will go out of the city to fight a decisive battle with us, and if the enemy doesn't care, just so we can make another deal!"

"We won't suffer any losses, anyway, I won't lose a lot of my troops!" William said, looking at the walls of Issamdenburg.
