"Boom!"

A stone as big as a millstone fell from the sky, but luckily it didn't hit anyone, but the loud noise made by the stone in contact with the wall was still terrifying.

If such a big stone hit a person, wouldn't it turn into a ball of flesh in an instant?

The defenders of Biduobao were frightened, and they all shrank behind the walls, not daring to show their faces.

Jaaisi, who was outside the wall, was very satisfied with the test firing of the trebuchet, and burst out laughing.

He slightly turned his head and praised: "Captain Doug, the technology you brought is really useful! I have been suffering from being unable to fight against the thunder hammer of the rebels. Now that I have created such a sharp weapon, it is not inferior to them."

The mercenary captain wearing a cloak on the side smiled slightly: "My lord, I'm flattered. But I would like to see what kind of magical weapon you are talking about [Thunder Hammer], and I hope they will hit it a few times."

Jiaai Si pointed at Bidowburg with a whip: "Here! That black thing on the wall is that, but... Hehe, it seems that without Greiman, the rest of the idiots can't play anymore, in vain Such a good weapon."

Before the attack, he took scouts to inspect Bidowburg carefully. There was no flag of the Greiman family or the Garnard family erected on the wall, but the flags of other families in the coalition army were all available. It seems that these two boys were indeed caught up in the territory, and their father's strategy really worked.

The mercenary captain Doug looked along the direction Jayce pointed. Even though he had excellent eyesight, he could only vaguely see at this distance.

He asked: "Master Viscount, after the battle is over, this [Thunder Hammer]..."

Jia Aisi smiled: "Don't worry, as long as you fight hard, half of you will naturally be indispensable."

"Thank you, my lord! Hey, we in the mercenary business like to collect some novel weapon research, and the more we know, the more security we have."

"Hmph, when you take down this castle, let alone Thunder Hammer, I'm still waiting to give you more things..."

…

While Jayce was talking with the mercenary captain, the lords of the coalition army were hiding in the strongest tower and losing their temper.

"Trash! Idiot! Being suppressed so quickly!"

"Once the instructor leaves, you don't know anything?"

When the instructors sent by Paul taught gunnery, they only slightly mentioned not to let the gunpowder get wet. This is common sense in the Arda army, so they didn't pay much attention to it.

Unexpectedly, the gunner selected by the coalition forces was completely immersed in the great power of the artillery. The instructor's sentence "don't let the gunpowder get wet" entered from the left ear and then came out from the right ear.

Before the Kent family's army arrived, the artillery instructors withdrew to Arda along with the transport company responsible for transporting the supplies. Paul didn't want his precious artillery to stay in such a dangerous place where his own army could not support.

The new rookie artillerymen of the coalition forces took out all the gunpowder used for firing from the warehouse and piled them under the city wall on their own.

Unfortunately, shortly before the arrival of the Kent army, a moderate rain fell over Pittburgh.

When the Kent army placed the catapults, the coalition lords confidently ordered their artillery to take the lead and blast them to pieces before the catapults were ready.

Then, under the eyes of everyone, the four artillery pieces that were supposed to have outstanding performance... misfired!

It was only then that everyone remembered that gunpowder should never get wet!

Without the help of artillery, the coalition forces could only watch helplessly as the trebuchets of the Kent army were ready, throwing stones the size of millstones on their heads again and again.

"Ah! Ah! What are you doing?"

Viscount Johnston took out his sword and waved it around in the air! It seems that he is so angry that he wants to kill someone! Several officers in charge of the artillery knelt on the ground tremblingly.

But the viscount restrained himself. These officers and soldiers who learned how to handle artillery are very precious, and they are trusted people in various families.

Earl Parker shouted angrily with a gloomy face: "Hurry up and take the gunpowder to dry while the sun is out."

Earl Malcolm also waved his fist fiercely: "If something goes wrong again, be careful with your heads."

Several artillery officers immediately rushed away with their heads in their hands.

The lords were speechless, and Derrick said leisurely, "We can only hold on for a while. Fortunately, we still have a dozen boxes of grenades."

…

Just as the war was rekindled in Biduobao, Arda's army's [Operation Overlord] also started.

On the river north of Yuwei Town, four sailing warships lined up, their black muzzles staring at the town.

Although it is called a town, it can be regarded as a small city in terms of scale. The city wall on the north side is built along the river, and there are water gates on it, the outer river and the artificial waterway inside the city.

Schroeder stood on the flagship deck, holding up the binoculars calmly and looking into the town, beside him were Alman and Tirpitz.

The commanders of the two fleets looked a little anxious, Tirpitz kept mumbling "why haven't you come back", and Arman looked at his pocket watch from time to time.

Just as they were waiting anxiously, the water gate on the city wall opened, and a small city came out~lightnovelpub.net~ and came straight to the flagship.

After the boat was posted on the board, an officer climbed onto the deck and came to Schroeder.

"Unfortunately, Viscount Solo Carter did not accept our persuasion! This is his reply letter."

Schroeder finally opened the envelope, read the reply letter carefully, and then handed it over to Tirpitz and Yarman.

Tirpitz was furious after reading it. Although the wording in the letter was more tactful, he scolded Paul Greiman for joining the [injustice] side and [betraying] the new Duke.

"Master Schroeder, let's start the attack. Claude and Baron Andrew have already landed at the west gate, and they are waiting for your order."

Schroeder took out his pocket watch and nodded.

"start to act!"

Following his order, the four battleships immediately became noisy.

Less than a minute later, a huge roar sounded from the south-facing side of the warships.

In an instant, Yuwei Town was baptized by dozens of shells.

Some shells knocked down the city wall, splashing bricks and stones, and the soldiers on the wall suffered.

Some shells crossed the city wall and knocked down the houses in the town. The red-hot shells ignited a raging fire after touching combustibles.

"It's Thunder Hammer! It's the legendary Thunder Hammer!"

"Quick! Hurry up and counterattack with the ballista!"

The defenders on the top of the wall were either huddled behind the wall in fright, or scurrying around like headless flies.

The soldiers in charge of operating the ballista bravely stayed beside the ballista, turning the torque winch with all their might so that they could shoot farther.

The officer in charge shouted, "Launch!"

The torsion spring drives the arm of the crossbow to drive the bowstring, and the four thick crossbow arrows are shot out quickly, flying towards the fleet of Arda...
