At the end of the order, the three armourers came together carrying a large wooden box, and after walking behind the Wu Shi Shi gun, they pried open the large wooden box, revealing the true face of the large wooden box, which contained only a large black metal oval object except for several thick layers of straw.

This is the new type of shell!

At first, Zheng Yue believed that when the round shell exploded for the first time in the barrel, the explosion energy was released to the barrel, and the energy could not be compressed at the bottom of the barrel, so that the barrel was under great pressure, and the pressure on the barrel was large, the faster the barrel was lost, and the thrust generated by the shell could not hit the shell farther.

After Zheng Yue put forward this idea, Fang Zi gave him support and asked him to try to develop a new type of cannonball, and gave him a group of gunpowder armorers to study a new type of cannonball together, and finally in less than ten days, Zheng Yue developed a rice-shaped cannonball!

This kind of rice-grained shell does not need to ignite the fuse in advance, it does not have a fuse, and it does not need to be stuffed from the top of the barrel, and a kind of rear-entry projectile pushing device is designed directly under the barrel, and then the shell is stuffed into the device, and the shell is ignited with a relatively thick firing pin, and the firing pin quickly hits the bottom of the shell, and generates pressure to the bottom of the shell, thereby igniting the gunpowder at the bottom of the gun.

In this way, the pressure generated by the cannonball can be compressed at the bottom of the cannonball, just like a person's feet are concentrated on a point to step on and jump, which can greatly increase the range of the cannonball, and this kind of cannonball has been tested and the test effect is very good.

Let's take a recently tested artillery as an example, Wu Shi No. 3 artillery, Wu Shi No. 3 artillery is used with this kind of shell, flat fire can shoot 400 steps, the longest range of 1,200 steps, originally Wu Shi No. 3 artillery has been considered a successful test, but the service life is too short, continuous shelling 20 times, the barrel is not wasted, the gun carriage is wasted, it is precisely because of this that the gun carriage of Wu Shi Shi gun has become so large, and two oblique large iron brackets and more than 1,000 pounds of large iron wheels are added.

This is only a new device visible on the outside, and there are also a lot of absorbing and buffering parts added to the inside of the artillery, so to speak, the internal parts of a Wu Shi Shi gun are as high as more than 300, and if someone wants to imitate it, they can't make a drawing for them.

The industrial gap between the Great Qin Dynasty and the countries is too big, the Great Qin already has a preliminary industrial system, and many places that require a lot of manpower no longer need a lot of manpower, only a few people need to control the machinery, and the countries are still in the era when manpower is king.

After the big wooden box was opened, a strong armorer held the cannonball with both hands, this cannonball was about forty pounds, absolutely big, and at the same time as the armorer held the cannonball, another armorer opened the rear-entry bullet pushing device, and then the armorer holding the cannonball stuffed the cannonball into the barrel and locked the projectile pushing device.

Everything is ready and waiting to be fired!

"Target 500 steps away from the wall, fire!" Fang Zi shouted solemnly!

As the words fell, the two armourers pulled a thick rope and pulled hard, a firing device that touched the firing pin through the circlip and ignited the gunpowder at the bottom of the shell!

"Boom!"

The body of the Wu Shi Shi artillery shook, and a thick layer of dust shook around the artillery, and the dust instantly enveloped the whole body of the artillery, and also blocked the twenty armorers including Fang Zi, and at the moment when the dust was raised, the barrel of the four-finger and two-section caliber spewed out a furious flame, and then an invisible shell burst out from the muzzle of the gun, shooting towards the target five hundred steps away!

"Boom-"

There was a violent bang, and the high wall five hundred steps away was instantly shrouded in firelight, and then a blazing heat wave carried billowing smoke and dust swept away, even the armorers standing five hundred steps away could clearly feel the violent shaking from the earth, and they were also blown back by the heat wave carrying billowing smoke and dust.

This explosion, within a radius of five miles can feel a strong tremor, within a radius of ten miles, can hear the roaring explosion, fortunately this radius of twenty miles is no man's land, otherwise, it will attract hundreds of people to watch, some people who believe in God will also mistakenly think that the gods descend to earth.

After about a few tens of breaths dissipated, the smoke and heat wave were blown away by nature, and the weapons test site returned to calm, and everyone looked at it, only to see that the wall 500 steps away had been blown to slag, leaving only the blackened scorched earth within a radius of 30 steps from the center of the explosion.

Seeing this scene, Fang Zi, who had been nervous, breathed a sigh of relief, and a faint smile appeared on the corner of his mouth.

The power of the shells is up to standard, and the range is up to the mark!

"It's too powerful!"

"If artillery enters the war, it will be an unbeatable force!"

"The world is so big, there is no zone that can stop my Great Qin King's Division, Great Qin is expected to be unified, and the world is the same!"

"Ladies and gentlemen, we will become celebrities who promote the development of history, and the future history books will have our names, and the hegemony of Great Qin will also have our credit!"

"Long live Great Qin! Great Qin is invincible! ”

The faces of the armorers could not hide their excitement, and they all danced and cheered.

As an armourer, there is no happiest moment than the moment when the weapon test is successful!

Fang Zi retracted the smile on his face and shouted solemnly: "Okay, don't be too happy, check the status of the Wu Shixian artillery, and prepare for the second artillery test!" ”

"Howler!" The armorers cheered again, and then began to check the condition of the various parts of the Woods.

"Qi Yu Fang order, the barrel is slightly heated, negligible, there is no abnormality in appearance, and continuous shelling can be carried out!"

"The artillery carriage is intact!"

"The order is given, the parts are in good condition, and they can be shelled continuously!"

"Enlightenment Fang Order,.....

After checking the status of various parts of the artillery, the armorers reported to Fang Ling one after another, and when they heard that there was no abnormality in the various parts, the smiles on the faces of the armorers became even stronger, as if they saw the moment when the artillery was completely formed!

"The results of the first test of the Wu Shi Shi gun: the gun carriage is intact; The barrel is slightly heated, and it can carry out continuous and heavy shelling; There is no abnormality in the condition of the parts! Zheng Yue summarized the situation reported by the armorers, and then informed Fang Zi.

Fang Zi nodded with satisfaction, and then began a series of continuous shelling by flat fire, trying to test the hit deviation of flat fire, that is, calculating accuracy!

"Boom-"

"Boom-"

Bursts of roaring sound resounded endlessly in the weapons test site, blasting out one after another blackened scorched earth craters.

PS: "Brothers, all the orders go, all the orders go, each of your full orders is the greatest support for the author!" ”
