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

And it is impossible for the thrown stones to reach such a large weight, and the most important thing is that there is a long piece of soft rope in the middle of this trebuchet, why is it so accurate?! More precise than their traditional stones placed in a frame mounted on top of a long pole.

"Hurry up and add weight! Load a 70kg stone bullet, aim at the city wall, and test the damage to the city wall! Several engineers in charge of the projection quickly calculated a few times, and then spoke loudly.

"Yes!"

A few soldiers quickly began to operate, and soon an even larger stone projectile was placed in the slide. When the two stone projectiles were once again fired with the terrifying sound of trebuchets, this time they smashed precisely on the walls below the tower.

The city wall in the distance soon emitted two huge clouds of smoke and dust, and then two loud noises of "boom" and "boom" followed, and when the smoke and dust were blown away by the wind, Li Daozong and they saw that the stone bullet that just smashed on the upper part of the city wall directly blasted two gaps in the city wall.

The two huge gaps collapsed along with the female wall above, and the power was ...... Simply so!

"Push, push 50 meters away! Test 100 kg stone projectiles! The engineer in charge of the measurement was excited, and exhaled loudly.

Dozens of soldiers next to them immediately pulled a specially reinforced four-wheeled carriage over and pushed it directly under the weight box, and then they slowly lowered the weight box to the center of the carriage, and then untied the link structure on the weight box.

A few more horses were found to pull the multi-ton counterweight box straight away, and then began 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 that the rope and the slide rail below are added, which extends the long rod arm in disguise, as for the small torsion trebuchet, the power of that thing is too small, and it is often used to kill.

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

This...... Directly dismantle and transport the weight box with the breeding? Although it is impossible to travel long distances, it can save too much time by moving dozens of meters to reinstall and use.

Soon the large trebuchet was reassembled, and this time on the largest stone projectile projected by the trebuchet, 100 kg of stone projectile.

When the stone bullet 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 wall of Gaochang City was only about five meters, not even half of Chang'an City.

But the thickness of five meters is not something that can collapse once or twice, but the collapse of the outer side of the city wall is already inevitable.

The four dense gaps had already produced a partial chain reaction, with a large piece collapsing down in the middle, and the collapsed rubble piled up in the trench beneath the city wall, filling the trench quite a bit.

This power ...... It's really several times more powerful than before! As for the stone bullet thing, there are mountains all around here, and there is no shortage of it.

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

The trebuchet stopped quickly, and two special carriages were pulled over, not cargo, but real three-bow large bed crossbows, and even the crossbow arms were thickened, and the three bow arms were placed in two upside down.

It is also equipped with a movable pulley set to lengthen the crossbow string to increase the power!

When this thing was pulled out, Li Daozong and the others all gasped, this thing ...... You're going to die next to each other, right? Because Li Daozong had already seen the crossbow arrows it used, probably the thickness of an adult's arm, the wooden shaft, and the iron arrow.

"Come on, come on, go up the siege arrows, try the color!" The craftsman who tested it was obviously excited, and spoke directly and loudly.

Li Daozong noticed that the other party had replaced a crossbow arrow with a sharp iron arrow with a circular structure.

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

"We wanted to see if this kind of arrow could make a hole in the gate if it shot it directly. Because the city gate is often wrapped in iron sheets, built-in wood, using this kind of arrow, all the power of the crossbow arrows will act on the iron sheet, whether it can be shot through or not will cause huge damage to the structure of the city gate, if a few more arrows may make the city gate fall apart directly! The engineer said excitedly.

Li Daozong: The path that "......" never envisioned.

However, he also knew that this was a test task assigned by His Highness, so naturally he didn't have any opinions.

This crossbow is much faster than a trebuchet! Because of the addition of movable pulleys, it does not use a winch for winding, of course, it is also possible. Now, for the sake of speed, it is directly used to pull the crossbow string with two horses for fast winding.

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

A unique crossbow beep sounded, and the terrifying crossbow arrows could not be caught by the naked eye, but the distance from the city gate was only more than two hundred meters.

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

Li Daozong immediately picked up his binoculars and looked at it, and when he saw the situation inside the door clearly, his whole face was very strange.

This thing...... Is it really possible?

For one of the two gates in the hole had been broken with a hole the size of a basin, and the parts that were not broken were also a little deformed and distorted.

In addition, the crossbow arrows seem to have been shot at the edge of the door frame in the middle of a city gate, which is often the thickest and strongest place for clad iron, and the crossbow arrows did not penetrate the city gate, but there was a huge gap between the two city gates, and it should be that the latch structure behind the city gate was destroyed by a huge force, although it was not completely damaged, but it was not so tightly sealed.

"Wind! Try shooting the castle tower! The engineer was excited and shouted loudly.

The two crossbow arrows were directly put up again, still the same spherical iron arrows as before, and this time they were aimed at the castle tower.

"Hum" two more crossbow arrows were fired, but this time, I don't know if it was too lucky, one crossbow shot directly into a wooden load-bearing pillar on the outside of the castle tower.

A huge popping sound sounded, and the wooden load-bearing pillar exploded directly, and then the structure of the city tower that had just been smashed by the stone thrower with a big hole was destroyed, and under the stunned gaze of everyone, a small cloud of dust came out of the city tower, and then collapsed directly to one side.

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

"Hahahaha! That's what you want! Try replacing the climbing arrows! ”

"Yes!"

The brand-new crossbow bolts were wound again, but this time Li Daozong noticed that these crossbow arrows were no longer wooden shafts, although they had become thinner, but they were pure iron shafts.

This time the bolts were aimed directly at the walls.

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

If there were more of that...... Soldiers can climb up with these bolts!

This is a natural ladder, and the enemy can't 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 morale of the army by the way.

But just as he stepped on the city wall, a stone bullet just whizzed, and then their tower was smashed directly out of a hole.

was so frightened that Ju Zhisheng's whole ass fell to the ground, and the ministers around him were even more unbearable!

Then they quickly retreated, and witnessed Datang's siege weapon test on the side!

"Surrender! Surrender! Send someone out! We surrendered! "Ju Zhisheng collapsed, and it was only an hour or two before the city tower was destroyed and half of the city wall collapsed...... Can they really hold out for twenty days?!

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