Chapter 207 Catapult Unit
Although the surface is very calm, Li Si is actually quite anxious in his heart. While thinking about the information about the Lei Guang insect demon given by Qin Qiong, he hurried straight to No. [-] Cemetery Street. Here, hundreds of craftsmen are busy making a group of Groups of spring steel sheets are assembled, and then gradually assembled into extra-large catapults.

In fact, this is Li Si's hole card, really, no mystery.

Because he had already tested it before, and the data obtained made him quite satisfied.

Based on the simple hourglass he made, he roughly calculated the time from launch to the landing of a 200-jin stone bomb, as well as the approximate distance, and then referred to the height drop of about [-] meters from the top of the mountain to the foot of the mountain. The final result is very likely Will blow up a Tiger tank.

He felt it was strong.

But now he felt a little overwhelmed.

"Ellende, don't rush to assemble the second one. Pick fifty of the most skilled craftsmen and add another fifty mules to the first catapult. In addition, arrange people. I want you to use the shortest possible time to give I melted and cast thirty solid iron balls weighing 1000 jin."

"Your Majesty, this will mess up the accuracy of the trebuchet. In addition, five hundred catties is already the limit that the spring steel can eject."

Blacksmith Erlund shouted in surprise.

"I know, I have a way."

Li Si said in a deep voice, his so-called method is to greatly strengthen the spring steel sheets. Of course, the supporting gears and bearings also need to be strengthened. It may be successful or it may not be successful, but it must be tried, just in case it works. Well, it's better than taking advantage of Qin Qiong.

Next, Li Si began to quantitatively and accurately strengthen the first catapult unit, especially the spring steel sheet. It must be ensured that the supernatural substances used are of the same type, and the number of reinforcements must also be consistent, otherwise accidents will easily occur.

After the strengthening was completed, the casting of the big iron balls was completed, and after polishing, Li Si immediately asked the coachman to drive a hundred mules slowly to pull the gears, and then through the power of the gears, groups of spring steel The sheet was stretched and bent, and everyone was terrified during this process, because the power accumulated on it was too terrifying.

"Your Majesty, the large gear set has turned 12 more times than before, and the small gear set has turned 36 times more than before, so that the bending of the spring steel sheet is pulled to the card slot, which means—maybe it is feasible. "

Erlund was so excited that his eyes glistened, because he had never seen steel with such good elasticity and toughness, and when he thought about the fact that the solid iron ball weighing one thousand catties was placed on it, he was really, really nervous.

If they were not careful, they would all have to die suddenly on the spot.

It took a full 5 minutes before the overall strengthened catapult unit entered the firing state, and on the other side, the large iron balls that had just been cast and were still hot were lifted one by one and put into the throwing part.

At the same time, Ye Bushou was carefully adjusting the ruler on the trebuchet, and a projection ruler comparison table was placed in front of him.

"Ruler 0, prepare to throw stones!"

Soon, the semaphore was played on the ground all night long, repeating, "Ruler 0, prepare to throw stones!"

300 meters away, the third Yebushou stood on the city wall and played the same semaphore.

800 meters away, a total of six nights are not closed, each with an interval of 100 meters, standing in a fan-shaped area, and playing semaphore.

On both sides of this area, there are still several Yebushou who are preparing to observe.

Their eyeballs are comparable to measuring rulers. The test shooting ruler of the trebuchet is their best skill. At present, the craftsmen have not yet developed a more precise control ruler, otherwise the trebuchet machine will be a trivial matter.

This is the meaning of the existence of special arms.

It can turn a simple thing into a miracle.

"emission!"

After receiving the information from the ranging team, Ye Bushou, who was in charge of the launch of the catapult crew, yelled. In an instant, behind him, two strong men, one violently pulled a huge metal wrench, and the other violently Push a gear device, this is a safety launch device made by Li Si, similar to clutch gear, you can switch between different spring steel sheet groups through the rotation of the gear.

This link alone saves a lot of manpower.

At the same time, it can also maximize the shooting accuracy, because the first spring steel plate group will be rotated by the central gear immediately after the ejection is completed, and it will enter the ready state. At this time, only one more group of people can pass through the clutch device. , switch it to the power storage gear set, after the power storage is completed, lock the safety card slot, and then continue to switch to the central gear set.

And the one hundred mules that have been charged can run non-stop, providing a steady stream of power.

"call!"

There was a violent sound of breaking through the air, and the iron ball was ejected by a huge force. It flew out of the underground launch hole in an instant, passed through the bunker, and flew up to a height of hundreds of meters. Only then did it draw a curved trajectory towards Fall to the predetermined area.

In the eyes of ordinary people, nothing can be seen, but in Ye Bushou's eyes, this iron ball is already very different.

"The height is between 130 meters and 150 meters, and the estimated landing point is between 700 and [-] meters!"

"The iron ball deviates to the north, and the wind is to the southeast!"

"Val, fly at an altitude of 150 meters and watch the wind speed!"

"The iron ball landed, and the projected straight-line distance was 54 meters longer than planned, and the vertical offset was 30 meters."

"The wind speed came out, and Weier said that at an altitude of 150 meters, the wind speed is five."

A series of semaphores were quickly gathered, and then passed to the bottom through the Yebubu observer above, and Li Si had already spread out the white paper, brushed and calculated for a while, and then gave the data needed by the Yebubu shooter.

In a short while, a new scale map was freshly released.

But this time it was not a random test shooting. At the foot of the mountain, Yebushou had already drawn a large circle on the ground, and then gave the location coordinates through the semaphore, which was then translated by the observer, and then quickly conveyed. It took less than ten seconds , the main operator has readjusted the scale of the trebuchet.

"emission!"

"call!"

With the violent rebound of the spring steel group, the iron ball flew into the air rapidly, and after a few seconds, the sound of the observation hand sounded.

"One hit!"

"The target is moving, moving one square for every count due east!"

This is a moving target, one count is one second, each count is one second, one frame is ten meters, one second is ten meters, these grandchildren, how about showing off their skills in front of Lao Tzu?
Li Si heaved a long sigh of relief, he no longer cared whether the third shot could hit or not, because if the target was the Lightning Insect Demon, he would definitely be able to hit it. In this regard, he can always trust the professionalism of these nights.

To be honest, asking them to be scouts is actually a waste of talent, they are simply the most powerful artillery.

Of course, this is because Li Si has never seen what real artillery looks like.

He did the mental calculation directly, and he smiled slightly. He was very satisfied with that terrifying damage figure. This is the correct way to open up extraordinary power.

However, this round of strengthening also used up almost [-] points of extraordinary substance.

"It would be great if we could use this extraordinary substance as a power source, but unfortunately I don't have this technology."

Li Si said with emotion that so far, he found that the highest utilization rate of extraordinary substances is destiny, with a utilization rate of more than 90.00%.

And if he uses it himself, whether it is preparing potions or strengthening equipment, the utilization rate will not be too high.

Therefore, Li Si infers that the utilization rate of supernatural substances determines the level of strength, and even the level of civilization, and it may also be related to the structure of Jiuchongtian.

Next, Li Si waited until all the [-] iron balls were tested, and quickly checked the degree of wear and tear of the spring steel sheets. If there were no reinforced steel sheets, he really couldn't check, but after using the extraordinary After material strengthening, he only needs to take a look to see the gap.

This can be regarded as a special boost brought to him by the Saber of Destiny.

It can be said that the induction of extraordinary matter is not bad at all.

"Not bad! According to this strength, these spring steel sheets can be fired at least fifty times before the enchantment enhancement effect is consumed. It's just a waste of ammunition."

Li Si thought helplessly, one iron ball needs a thousand catties, and he just ordered Erlund to cast thirty, which basically used up today's molten iron in the furnace.

If the iron ball cannot be recovered, then it will be troublesome.

Because the iron ball has a high density and a small volume, the wind resistance will also be much smaller, which can affect the accuracy.

Where can it compare to a stone ball, you don't have to worry about throwing it out.

It seems that this matter still has to trouble Boss Qin. A boss like him must have a lot of residual value.

About two hours later, Li Si's scalp suddenly felt a little numb. It seemed that countless steel needles pierced through the black mist in the distance, which made his whole thinking stagnate.

Until the Destiny Saber erupted with brilliant brilliance, mixed with the sunlight in the sky, and instantly formed a seven-color glazed shield, which was buckled upside down within a radius of thirty miles.

"Zizzizi!"

And at the moment when the colorful glazed shield was formed, countless black snakes collided with it, instantly burning and turning into nothingness.

A few seconds later, the little black snake disappeared, and the seven-color glazed shield also dissipated. It was just this wave that consumed Li Si's [-] points of extraordinary substance.

"Your Majesty, protect Your Majesty!"

When a faint voice came, Li Sicai seemed to come back to life, but he himself turned into a blood gourd.

But looking at other people, they didn't feel anything at all. Not only were they not attacked, but they didn't even see the seven-colored glazed shield.

"I am fine."

Li Si lamented in his heart, he suddenly realized that holding a weapon of destiny did not seem to be a good thing.

"Boom boom boom!"

The earth shook and the mountains shook, the magic wind rolled up, and the black mist stretched its teeth and claws. Accompanied by this movement, a huge monster with a height of more than [-] meters slowly climbed out of the black mist. It was really a mountain!

In the mountain city, everyone's eyes widened, and their hearts felt cold.

Even Qin Qiong yelled, it's hard, why is there a BOSS?

This level of Lei Guang Bug Demon is only one step away from becoming a female insect, and it is rarely seen on the frontal battlefield of the first heaven.

A few months ago, a main city of the fifth group of Mengyuan was forcibly pushed down by a whole nine thunder-light insect demon bosses.

Although there is only one head at the moment, it is definitely not something that can be contended with.

This Li Si is really a loser.

Gritting his teeth, Qin Qiong called out his nine-star war horse, took out his seven-star historical weapon, dressed neatly, and was about to lead his men to break through the formation and turn in.

Now he understands that although Li Si is bound and fused with the primary destiny, he has really become the primary target of the monsters.

However, just when he was about to rush out of the city, Qin Qiong jumped in front of his eyes. He could see vast and mighty formations in all directions. I don’t know how many monsters and monsters were lined up densely. This kind of force should at least be regarded as a main battle regiment. The mother worm sits in town.

"It's miserable!"

Qin Qiong's face turned pale in an instant, why is Lao Tzu so unlucky!With the female worm in charge, even if he wanted to break through, he would have no chance.

Even if he is careless, even his body will become a bug demon.
