Datang: Li Shimin begged me to rebel

Is this the brand new trebuchet?This projection distance is far beyond their previous traditional trebuchets. Li Daozong and An Xinggui have seen traditional trebuchets before. Traditional trebuchets can only have two-thirds of the range at most, or even closer.

Moreover, it is impossible for the thrown stones to reach such a heavy weight. The most important thing is, why is this trebuchet so accurate even though there is a long piece of soft rope in the middle? !Much more precise than their traditional way of placing stones in frames mounted on top of long poles.

"Quickly increase the weight! Load 70 kg of stone bombs, aim at the city wall, and test the damage to the city wall!" Several engineers in charge of projection quickly calculated a few times, and then said loudly.

"Yes!"

Several soldiers quickly began to operate, and soon a larger stone bomb was placed in the slide rail.When the two stone bombs were thrown out again with the terrifying sound of the trebuchet, this time they precisely hit the city wall below the tower.

Two huge clouds of smoke and dust soon appeared from the city wall in the distance, followed by two loud bangs of "boom" and "boom". Half of the stone bombs directly blasted two gaps in the top of the city wall.

The two huge gaps collapsed together with the female wall above, this power... simply!

"Advance, advance a distance of 50 meters! Test a 100-kilogram stone bomb!" The engineer in charge of the measurement was excited and shouted loudly.

Dozens of soldiers next to it immediately pulled a four-wheeled carriage with a special reinforced structure and pushed it directly under the weight box. Then they slowly lowered the weight box to the center of the carriage, and then released the link structure above the weight box.

Find a few more horses to pull the several-ton counterweight box directly away, and then start to push the remaining catapult structure forward.

Li Daozong and An Xinggui were a little stunned. In fact, the only difference between the counterweight trebuchet and the traditional large trebuchet is the addition of ropes and slide rails below, which in disguise extend the arm of the long pole. As for the small torsion trebuchet, that thing is powerful. If it is too small, it is often used mainly for killing.

And when their traditional large trebuchets were moving, the stones and breeding in the counterweight box must be taken out before they can be moved.

This... just dismantle the counterweight box and even breed it and transport it away?Although it is impossible to travel long distances, moving tens of meters to reinstall and use will save a lot of time.

Soon the large trebuchet was reassembled, this time with the largest stone projectile projected by the trebuchet, a 100kg stone projectile.

When the stone bomb was bombarded on the city wall again, two huge gaps appeared next to the two gaps just now. Although the city wall as a whole did not collapse, after all, the thickness of the Gaochang city wall was only about five meters, and even half of Chang'an City less than.

However, the thickness of five meters is not something that can be collapsed once or twice, but the collapse of the outside of the city wall is inevitable.

The four dense gaps have already produced a partial chain reaction, and a large piece of it collapsed directly in the middle, and the collapsed rubble piled up in the ditch under the city wall, filling up the ditch by a lot.

This power... is indeed several times greater than their previous power!As for the stone bomb, there are mountains around here, so there is no shortage at all.

"Stop for a moment and test the large siege crossbow!" The craftsman in charge of the test over there said loudly excitedly.

The trebuchet here stopped quickly, and two special carriages were pulled over. These two carriages were not pulling goods, but real three-bow large bed crossbows, and even the arms of the crossbows were thickened. The three bow arms are arranged two upright and one upside down.

The movable pulley block is also installed to lengthen the crossbow string to enhance the power!

When this thing was pulled out, Li Daozong and the others gasped. This thing...will die right next to it?Because Li Daozong had already seen the crossbow arrows it used, probably with thick adult arms, wooden arrow shafts, and iron arrowheads.

"Come, come, get the siege arrow, and try it out!" The test craftsman was obviously very excited, and said loudly.

Li Daozong noticed that the opponent replaced a sharp iron arrow with a round structure.

"What does this mean?" Li Daozong was a little curious, isn't the sharper the arrow, the better?

"We want to see if this kind of arrow can open a hole in the city gate if it shoots directly at the city gate. Because city gates are often wrapped with iron sheets and built with wood, with this kind of arrow, all the force of the crossbow will act on the iron sheet, No matter whether it can be shot through or not, it will cause huge damage to the structure of the city gate, if a few more arrows may be able to directly disintegrate the city gate!" The engineer said excitedly.

Li Daozong: "..." A road that was never imagined.

However, he also knew that these were all test tasks assigned by His Highness, so naturally he had no objections.

This bed crossbow is much faster than the trebuchet!Because of the addition of a movable pulley, it does not use a winch to wind up, of course it is also possible.But now, for the sake of speed, two horses are directly used to pull the crossbow string for fast winding.

Soon, when the two crossbow bolts were installed, they aimed directly at the gate of the capital of Gaochang, and then slammed the trigger.

There was a unique buzzing of the crossbow strings, and the terrifying crossbow bolts could not be caught by the naked eye, but the distance from the city gate was only more than 200 meters.

Then there was a "boom", and two loud noises came from the doorway.

Li Daozong immediately picked up his binoculars and looked over. When he saw the situation inside the doorway clearly, his whole face was very strange.

This thing...is it really feasible?

Because of the two city gates inside the gate hole, a hole the size of a washbasin has been broken in one of the city gates, and the parts that are not damaged are also deformed and distorted.

In addition, the crossbow arrows seemed to hit the edge of the door frame in the middle of a city gate, which is often the place where the iron cladding is thickest and strongest. The crossbow arrows did not shoot through the city gate, but there was a huge gap between the two city gates. , It should be that the latch structure behind the city gate was destroyed by a huge force. Although it was not completely damaged, it was not so tight anymore.

"Turn on the string! Try to shoot the city tower!" The engineer was very excited and shouted loudly.

The two crossbow arrows were directly put up again, still the spherical iron arrows just now, this time they aimed at the tower.

"Om" two more crossbow arrows were fired, but this time, I don't know if it was luck, one crossbow arrow directly hit a wooden load-bearing column on the outside of the tower.

There was a huge cracking sound of "Boom", and the wooden load-bearing column exploded directly, and then the structure of the tower that had just been smashed into a big hole by the trebuchet was destroyed. A small cloud of dust came out, and then collapsed directly to one side.

As for the other crossbow arrow, it passed directly through the tower.

"Hahahaha! This effect is what I want! Try changing the climbing arrow!"

"Yes!"

Brand new crossbows were wound up again, but this time Li Daozong noticed that these crossbows were no longer wooden shafts, although they had become thinner, they were pure iron shafts.

This time the crossbow was aimed directly at the city wall.

With a sound of "hum", Li Daozong immediately picked up the binoculars as the sound of the crossbow strings sounded, and two crossbow arrows had been deeply inserted into the city wall of Gaochang Kingdom.

If there are more of these... Soldiers can climb up directly by stepping on these crossbow bolts!

This is a natural ladder, and the enemy has no way to destroy it.

The engineers below were excitedly testing, but what Li Daozong and An Xinggui didn't know was that before they tested, Ju Zhisheng just wanted to come over to the city wall to see the situation, inspect it, and encourage the soldiers by the way.

But just as he stepped onto the city wall, a stone bomb just whizzed towards them, and then their tower was directly smashed out of a hole.

Ju Zhisheng was so scared that he fell to the ground with his ass, and the ministers around him were even more unbearable!

Then they quickly retreated to witness Datang's siege weapon test!

"Surrender! Surrender! Send people out! We surrendered!" Ju Zhisheng collapsed. It took only an hour or two before the city tower was destroyed and half of the city wall collapsed... Can they really hold on for 20 days? !

It's just that Ju Zhisheng didn't know what he was going to face next.
