After two days and nights of preparation, three groups of handymen prepared the timber according to Arrod's request, and the craftsmen made twenty wooden pillars with axes in proportion. Ten of them are 2.6 meters long, and the other ten are 5.5 meters long, the short ones are pillars, the long ones are piggybacks, 400 leather cords made of animal skins, and there are fragments of end wood with holes chiseled in the middle.

"Honorable lord, what is this?" Looking at the siege machine in front of him, an old craftsman asked in a hoarse voice, he had never seen such a weapon in his life working for the nobles.

"Whirlwind cannon." Arrod's eyes were red, and he looked tiredly at the lever principle formed by the power of the person pulling the piso, and threw about 2 kilograms of stones out of a hundred-meter whirlwind cannon, if it weren't for the lack of skilled craftsmen in time, Arold felt that the Roman catapult or Xiangfan cannon should be the most effective weapon against the castle, but the knights of Duke Mason could not break through the city wall several times, not because the city wall was very tall, the reason was that the archers and defenders on the city wall were relatively tenacious, While the Whirlwind Cannon may be less effective against the walls, it is more lethal against the archers and defenders on the walls.

"Arold, are you really sure you can take the castle with these things?" At this time, Baron Wendell and Yves came to Arold's side, and they looked at the pillar-like instruments, and did not understand how such things could have broken through Göttingenburg.

"Yves led our men to erect obstacles with shields a hundred meters from the castle." Arold did not know how lethal the Tornado Cannon would be to the castles of the medieval nobles, so he tried to shorten the distance at which the Whirlwind Cannon would be maximized.

"Alright, Arrod, I'll do it right away." Ifzhi said that Arrod's whimsical ideas had helped them several times, so he didn't ask anything anymore, anyway, he couldn't understand this kind of thing, so he called his armed servants to collect the shields, and erected the shields one by one at a distance of a hundred meters from the castle, and the guards on the walls of Göttingenburg saw that many people with shields suddenly came out of the Duke of Mason's position, and immediately became nervous and hurriedly bent their bows and arrows, and several anxious archers were impatient to shoot the arrows in their hands, The arrows swept over the heads of the armed servants in an arc, and several more were stuck in their shields, which they hurried to the rear.

"What are these guys doing?" The archers looked at the shields in the open space below the city, and the armed servants from under the shields galloped away like rabbits, a move that was completely unexpected for them.

"Don't let your guard down." Earl Ulrisi's lieutenant drew his sword and shouted to the defenders, confident that they would be able to repel the Masons' attack under the protection of the walls, though his mind was full of doubts.

"Yes." The soldiers, armed with spears and pointed iron helmets, thick linen shirts and trousers, and woolen shawls on their left shoulders, leaned their shields against the battlements, and pointed the tips of their spears at the outside of the city wall like hedgehogs, and looked at the thick formation that had been established on the wall, and the adjutant nodded with satisfaction, he thought that even all the knights of Duke Mason would not be able to attack it.

At this moment, the early morning sun rose from the edge of the forest outside the castle, and the sun shone on the city wall, and the people on the city wall felt that their eyes were a little uncomfortable, and they had to squint their eyes to look at the city wall, and some people's eyes couldn't help but be stung by the sun and shed tears. At the same moment, in the Duke Mason's position, the nobles saw Arrod followed by many handymen and craftsmen, and these sleepy-eyed nobles looked at the wooden pillars held by the handymen and craftsmen, and they yawned and asked each other what they were, but no one knew what they were.

"Hey, bitch, what are you taking?" A nobleman, holding a glass of wine, wearing chain mail and a smock, and one foot on a stake by the extinguished campfire, asked curiously to a handyman.

"Yes, yes, my lordship, I don't know what to do, but I've heard that it's a siege thing." The handyman hurriedly bowed and showed a flattering smile, but his mouth was full of rotten teeth, which made people unable to raise a good impression.

"Siege equipment, Haluha." Listening to the answer of the miscellaneous servant, the nobleman Ha Lu Ha Da Lu laughed, everyone knows that the wooden stake used to hit the city gate must be thick enough, well, just like the thing under himself, Ha Lu Ha, but this Ah Ruo, who has not grown any hair, has used something, and someone should teach him basic military knowledge.

"He's crazy, hahaha." The other nobles also shook their heads, and what Arold had done was completely beyond their comprehension and knowledge, and they couldn't help but feel sorry for the Duke of Mason for believing the wrong person.

"Send a detachment of handymen to dig a row of ten pits behind the shields, about ten paces apart from each other." Arold didn't care about the ridicule of the nobles, he picked up the drawings and carefully measured the distance between the castle and the whirlwind cannon, Baron Wendell also followed behind his second son, the newly promoted old baron was ready to fight side by side with his son, this was the first important battle of the Wendell family, Baron Wendell was full of confidence in his second son, of course, this confidence was based on Arrod's several times for the family.

A group of handymen braved the arrows from the walls above their heads and began to dig a pit behind the shields that had been erected earlier, which was much safer than having them rush to the castle with ladders, so that ten deep pits were dug ten paces apart, and Arold commanded the remaining handymen to insert a third of the ten cupolas, and a half of the two small pillars beside them, into the earth.

"Father and our armed servants are guarding around the whirlwind cannon to prevent the enemy from going out of the city and destroying it." Arold squinted his eyes and watched the movement on Göttingen Castle, he knew that the enemy still did not understand what he wanted to do, but once the whirlwind cannon was in effect, the commander in the city would definitely desperately want to destroy these weapons that could bring great damage to the castle, so Arold arranged for his family's armed forces to guard the side early.

The Cyclone Cannon is a medium-sized catapult weapon, and because if you want to build a heavy Tornado, you have to use harder metals such as iron in important parts, so the Cyclone Cannon is only a combination of wood and has limited capabilities, but even this flexibility is one of the advantages of the Cyclone.

"Piggyback, fifty miscellaneous men per whirlwind." Arold mobilized another 400 miscellaneous servants from the logistics camp, anyway, there were a lot of miscellaneous servants in the logistics camp of Duke Mason, and there were still women who wanted to join in the case of not enough, in the eyes of the Germans, it was very common for women to join the battlefield, and Arold refused the request of these women, because in his opinion, it was better for the war to let the women go away.

"God, what is this?" When the ten whirlwind cannons were loaded, the nobles of Duke Mason could almost stuff an apple with their mouths wide open, and they saw that these had forty leather cords like a woman's hair at one end, and a linen rope was tied on the other side, and the head of the rope was attached to a leather bag, and a stone of about 2 kilograms was placed in the leather bag.

"Are the Masons doing some kind of witchcraft?" The eyes of the adjutant and the soldiers on the battlements of Göttingen Castle widened at the sight of the row of tornado cannons stuck in the dirt, and the soldiers were only terrified of the hair-like pisos, and the adjutant, as a military nobleman, had a vague feeling that these things would pose a threat to the walls he was defending.

"Go and invite Lord Earl Ulrichie, the Masons seem to have some new tricks." The adjutant wiped his cheeks with the leather gloves on his hands, and he felt beads of sweat trickle down his helmet, and it wasn't very hot at this time.

"What about Arrod now?" Eves asked Arold with a puffed chest.

"Let's have a whirlwind cannon try." Arold gestured to a whirlwind cannon in the center.

"Whoosh~~." The whirlwind cannon's attendants, under the direction of Arold, put a stone in their skins, and then each of the forty servants grabbed a leather cord, and they yanked at Arold's slogan, and the stones in the leather pouches were thrown out of the coffin and flew over the open space between the castle and the shield under the effect of the lever principle, and landed under the base of the city wall with a snap, without causing any harm to the people on the wall.

"No, you have to listen to my slogan." Arold frowned, he saw that some of these untrained handymen were dragging early, some were late, and some were even standing there stupidly and motionless, because of the uneven force, so the first shell actually missed, which made Arold a little annoyed, and he shouted loudly.

"Damn it, whoever doesn't act under orders, I'll cut off his head." Yves was also furious, and he drew his sword and roared at the handymen, who nodded in fear at the sound of his roar.

"One more time, one, two, three drag~~~." Arold also knew the reason why Lu Daoci was not in charge of the army, he also drew his sword and shouted a slogan in his mouth, and swung his sword violently at Lu Xia at the third sound.

"Whoosh~~~, Ping." This time, the forty miscellaneous servants pulled the piso with all their might, and the stone flew out with a whoosh, and struck it against the walls of Göttingenburg, only to hear a muffled sound, and the stone hit the head of a spear soldier with a shield, and the soldier's head was like a watermelon that had been hit, and the red juice splashed everywhere, and the iron helmet on the soldier's head showed a bowl-sized depression.
