Chapter 652

Only then did Zhi Keshi notice that there were two more than one person tall and the other one was about two people tall, and the other was almost two people tall, which naturally looked so inconspicuous compared to these four huge wooden towers.

"This is the No. 0 prototype, the counterweight weighs about 500 catties, and it can throw a five-pound object 80 steps away." Wang Yang walked not far away, pointed to the stone-throwing machine that was only more than one person high, and then pointed to another two-person high stone-throwing machine.

"This is the No. 1 prototype, and its counterweight weighs 1,500 pounds, and it can throw fifteen-pound objects to a distance of 180 steps."

"Counterweight, isn't that what you mean?" He walked closer and took a few looks, and pointed to one of the long poles of the stone-throwing machine, where a large wooden basket had fallen, and the basket was filled with heavy stones.

"Yes, this is the counterweight, relying on the fall of the counterweight, the other end of this long rod is raised into the sky, and the weight in the bag is thrown into the distance."

While he was explaining to Zhi Keshi, a green-robed official hurried over and reported to Wang Yangyu. "My lord, the previous heavy load test has been tested, and the maximum loading of the four stone throwers has reached a weight of 10,000 catties, and there are no problems with the structure of the stone thrower and the load-bearing base."

"Is there any deformation in the structure?" Wang Yang asked the green-robed official several more questions that Zhi Keshi couldn't understand, and then nodded with satisfaction.

"Since there is no problem with the weighting, then we can start testing the projectile, right?" Wang Yang asked.

"Of course, there is no problem, but how much weight does this counterweight need to be loaded? And how many objects do we need to throw? The green-robed official asked Wang Yang.

Wang Yang touched his chin and looked at the four stone throwers. "The No. 1 machine is loaded with 4,000 catties, the projectile is based on 60 catties, the No. 2 machine is loaded with 6,000 catties, the projectile is based on 90 catties, the No. 3 machine is loaded with 8,000 catties, and the No. 4 machine is loaded with 10,000 catties, and the projectile is increased according to the proportion of 2,000 catties and 30 catties for each additional balance hammer, understand? ……”

The green-robed official respectfully took the order, and soon the craftsmen, who had been mostly idle, began to get busy again.

The stones that had already been brought in from elsewhere were weighed and then added to the counterweights of the four stone throwers.

Soon, the No. 1 machine was loaded, and then, someone began to put the hanging rope on the cattle and horses that had been waiting aside, under the pull of these animal forces, the No. 1 machine was originally towering, like a flagpole piercing the sky, and the length of the throwing rod reached five zhang with the slow downfall of the balance hammer.

Finally landed on the other side of the stone thrower, and when the counterweight reached the standard height, someone soon rushed over and tied the thick hemp rope tightly.

The animal force that had completed the task was pulled aside, and at this time, a craftsman, with some difficulty, carried a stone that had been weighed and weighed about sixty pounds into the leather pocket at the top of the long pole.

"Huh, this head doesn't seem to be wooden?" At this time, Zhe Keshi seemed to notice that the top shaft of the club, which was about five feet long, showed a metallic luster.

"What is used there is a soft steel similar to the one used in our Great Song Yuan Yu crossbow, this kind of soft steel is not only lightweight, but also has excellent elasticity, and the head used to assemble it can also ensure the firmness and toughness of this throwing rod." Wang Yang nodded and pointed to the long throwing pole.

Not only the head position, but even the side of the shaft that is now facing the ground, is also nailed with pieces of mild steel, mainly because the elasticity of these woods is enough, but the toughness and strength are insufficient.

In the end, it was Wang Wushan, the most famous and clever weapon expert in the Great Song Dynasty, who had an idea, and found the Yuan You crossbow arm that had not yet been assembled, and used it to reinforce it.

"How far can this go? If a 60-pound stone block is smashed on the city wall, I am afraid that it will have to smash a crack or even a gap. Zhi Keshi couldn't help but look a little nervous, he was really looking forward to Wang Yang, a Wang official who was always able to surprise people, to invent a sharp long-range weapon.

After Wang Yang strode closer, he pulled out the war knife from his waist, took a deep breath, and then slashed fiercely at the hemp rope that held the balance hammer and could not fall.

The hemp rope naturally couldn't stop the sharp blade, and it broke in response. I saw that the balance hammer hanging high in the air for a while, and then it crashed down, and the five-zhang long throwing rod brought a screaming sound, and suddenly drew an arc and stood upright, and even tilted forward at the top of the throwing rod for more than ten degrees.

Even the naked eye could barely tell how the stone was thrown out of the leather pocket, and the only thing one could notice was the dark gray mottled stone, tumbling and flying into the distance, and after flying for some distance, it fell downward to the ground in an arc.

The splashed snow and mud were mixed together, and for safety reasons, no one dared to stand in the direction of the target range for the test, but Wang Yang still easily came to the conclusion, and the distance was at least about 170 to 180 meters.

The No. 2 machine, which weighed 6,000 pounds with a counterweight, threw the 90-pound stone farther away, and the visual distance was at least 200 meters.

The next No. 3 machine did a beautiful job, and the boulder weighing 120 catties flew in the sky for a distance, and finally fell to a position of about 240 meters.

Every time a boulder hits the ground, the craftsmen involved in making the heavy stone thrower can't help but cheer. At the very least, the range and power of this heavy catapult have left the catapults that used to be pulled by human power far behind.

Zhi Keshi was stunned to see the boulder that flew to the far distance, and then fell to the ground, splashing snow foam and mud and grass clippings, and for a long time, he slowly turned his head and looked at Wang Yang.

And Wang Yang once again walked to the stone thrower with a load capacity of 10,000 catties, took a deep breath, once again raised the war knife in his hand, and slashed down fiercely, and in an instant, the thick hemp rope was directly cut off.

Then, the stone weighing one hundred and fifty catties accelerated and drew a graceful arc in everyone's sight, soaring towards the sky.

The irregular stone rolled in the sky, flew, flew over a great distance, and finally, smashed down hard......
