The Gonggong faction developed a process of modifying the crossbow, fixing a smoothbore barrel on the crossbow, loading a bullet, and installing a sliding guide rail behind the barrel, on which a sliding sleeve firing pin was installed, and when closed with the barrel, it was exactly on the same axis.

Use the power of the crossbow winding to hook the crossbow machine, when the crossbow machine is loosened, the bowstring drives the sleeve firing pin and hits the primer, which not only has an airtight effect, but also completes a shot at the same time, and the bowstring can be restored to a relaxed state when it is not used.

The barrel is made of a small-caliber seamless steel tube to form a smoothbore bore, and depending on the size of the crossbow, you can choose between pistol bullets and intermediate power rounds.

This design is suitable for the transformation of most crossbows in various countries, without re-production, only a slight modification, and even as long as the accessories and simple tools are provided, so that carpenters from various countries can build according to the drawings, and can be mass-produced.

Due to the use of ready-made small-caliber thick-walled seamless steel pipes and rotary body parts, the production is extremely convenient, and the problem of firepower is basically solved.

Of course, since it is a smoothbore barrel, there is definitely no guarantee of accuracy, but it is better than not having it, and of course it can be matched with rifled barrels if there are conditions.

In addition, it was suggested that the caliber of the heavy machine gun being studied and designed should be changed to 155 millimeters (about 14 millimeters), because they found that most of the axillary rifles were of 155 millimeter caliber, and if the caliber of this caliber was unified, the rifle captured from the axillary man could be used by humans after the firing pin was replaced, but the implication was that the Gang faction intended to use the captured arms to sell them for money. The transformation of the crossbow is obviously also to make money, to put it mildly, it is to make the princes' national fortune.

Of course, if the ammunition of both sides can be used, the axillary people can also use the human ammunition, but the problem is not so simple, the axillary people use black powder, and Bailiyan uses single-base and double-base propellants.

Single-base propellant is a safe smokeless gunpowder after the passivation of nitrocellulose cotton and ether ethanol, and the double-base gunpowder is actually a diatomaceous earth passivated nitroglycerin is added on the basis of safe smokeless gunpowder, and the heavy machine gun in research and development will be used in the navy and army, in order to achieve a longer range, the use of double-base gunpowder, so the cartridge and bolt, barrel processing technology and material performance requirements are very high.

In other words, the breech-loading rifles of the armpit men fired black powder, and the barrel could not withstand the chamber pressure and high-temperature ablation of the double-base gunpowder, so even if they captured the salty standard ammunition, they could not use it.

In addition, the kinetic energy of black powder is low, and the axillary warheads are mostly round-headed bullets, so the muzzle velocity is very low. The higher muzzle velocity means that while the gunpowder increases the chamber pressure, the high muzzle velocity warhead will also increase the chamber pressure, and the axillary gun cannot withstand such a high chamber pressure, and can only explode in the end.

Of course, the 155 millimeter bullets supplied to the princes also used black powder and round-tipped bullets, which were distinguished by different colors of lacquer and bullets.

The fact that such a captured weapon can equip human beings without wasting it shows how important independent industrial production capacity is, and it is estimated that the armpit people would never have dreamed that such a result would be.

After reading the design drawings and process descriptions of the Ligong School, Bai Liyan couldn't help laughing, and Zhao Anling was puzzled

"Why is Master Hou so happy, could it be that the Gong Gong faction has offered some good advice."

"Hehaha, sure enough, only interests can exhaust manpower. At present, the war in Sangbei has not yet ended, and the Ligong faction has already paid attention to the armpit equipment, but it can be regarded as a good strategy. Mr. Zhao, do you know how many armpit guns our troops have captured since the June naval battle? ”

"According to information from the Army Senate, more than 36,000 long and short guns and more than 1 million rounds of ammunition were seized."

"Yes, about 17,000 of them were breech-loading rifles. Yongxing City is developing high-speed heavy machine guns, and the Gonggong faction suggests using the axillary ammunition caliber, so that the ammunition produced in the future can also be used by the armpit man's gun. ”

"But if the armpit people seize the ammunition of our army, will they not suffer themselves."

"Hehaha, Mr. Zhao rest assured, this kind of ammunition used by the Xian army can not be used by the armpit rifle, and the ammunition supplied to the princes can only be used by the armpit people, so there is not much threat to our army."

The armpit man's rifle has many barrels, less double barrels and more four barrels, the weight is heavy, and people can't use it with it, and it's too hard to carry, so it can only be used for semi-fixed firepower, and other components are needed to facilitate human use, but at least it also solves the problem of whether the princes have or not.

"Mr. Zhao has heard about the Guangxin War."

"I've heard that the phone is open at twelve o'clock, and any news can be known in real time, which is so convenient, if it were changed to thirty years ago, I really can't imagine it."

Zhao Anling was full of emotion, and he had already admired Bailiyan's five-body body in his heart.

"Yes, the armpit people greatly underestimated the strength of our country, and it is for this reason that they want to destroy our country with all their might. This victory or defeat is a matter of future development, so this battle must be won again. Today, I also asked Mr. Zhao to rest for a day, and return to Xuan Yuncheng tomorrow to tell Lu Yan, so that he could quickly transport the frogman and equipment to Guangxin, I have an urgent need. ”

"Could it be that the Hou Ye is heading for the ironclad giant ship."

"Exactly, after winning, I will talk to Mr. in detail, I have to rush to Guangxin immediately today, so as not to delay the change for a long time."

With Zhao Anling and Ye Xin, Bailiyan held a military meeting to deploy the mission, set off for Beihai County in the afternoon of the same day, and arrived in Guangxin on October 22.

Before entering Guangxin City, Baili Yanyuan saw the four round behemoths, the smallest one had to be at least 120 meters in diameter, with 30 howitzers on the first deck and a circle of ordinary rapid-fire cannons on the lower deck.

The largest one reached a diameter of one hundred and fifty meters, with thirty-eight howitzers on the first deck and more than one hundred and thirty ordinary rapid-fire cannons on the lower deck.

The smallest one is equivalent to the displacement of a 20,000-ton battleship, and the largest is more than 30,000 tons, but due to its cylindrical ship type and conical conical bottom, the volume ratio is four times that of a 30,000-ton battleship, and the usable area of one deck is more than two football fields, so it is not difficult to arrange so many howitzers.

Previously, Bai Liyan had asserted that it was impossible to build cruisers, heavy cruisers, and even battleships above destroyers by riveting technology alone, because the force limit of the riveting process is only so much, and under the current technical conditions, it is already a limit. Without a breakthrough in material technology and manufacturing process, it is impossible to continue to develop.

However, the armpit people used the riveting process to build a warship of more than 10,000 tons, and the tank hull type is precisely better able to bear its own weight than the narrow and streamlined hull, so the riveting technology has made a breakthrough in the tank hull ship type.

At the cost of sacrificing seaworthiness and speed, multiple balances in floor area ratio, area, cargo and manufacturing technology can be achieved. It has to be said that the talent, imagination and creativity of different higher species are indeed incomparable with each other.

From then on, new technological paths and branches appeared in ship manufacturing, and Bai Liyan had to begin to doubt how much the cognition of the previous life could help the world in front of him.

When entering the city, the armpit people continued to bombard the concrete fortresses on the east and west flanks of Guangxin City, and the artillery on the upper surface of the Xianjun battery and the fortress was completely lost, and three of the twelve largest fortress guns were destroyed.

Because the range of the fortress cannon was too long, and the axillary ironclad ship was within two miles, located in the death limit area of the fortress gun, in order to preserve its strength, the remaining nine fortress guns returned to the cannon nest made of reinforced concrete through the guide rail, and sealed the entrance with a two-inch thick manganese steel door to resist the shelling.

The rest of the guns, located on the lower two floors of the fortress, could not fire because their muzzles were higher than horizontal and they were also in the shell death zone, so they had to hide in bunkers to avoid shelling.

The non-stop shelling that lasted for more than ten days consumed a large number of shells in the armpits, and the density of firepower has been weakened.

After entering the city, they went straight to the south of the city, and the headquarters of Jiang Gan, Sikong Nan, and Jiang Jie were set up in the underground bunker in the south of the city, and the family members were sent to Xuanyun early in the morning.

At the beginning of the construction of Guangxin infrastructure, Bailiyan suggested digging a large number of underground bunker fortifications to avoid shelling, and then with the participation of the tomb gangsters, a network of tunnels was built to connect the large shelters inside and outside the city, forming an underground city.

Soon after the shelling began, the people of the city either fled underground or were evacuated to other county towns for refuge, and although many casualties were avoided, the main urban areas of the city were also reduced to rubble.

The four round ironclad ships outside the harbor, each with more than thirty short-barreled howitzers on the surface of each deck, each of which was covered by a spherical cannon shield, with a caliber of 1560 millimeters, although it was only black powder, the range was enough to cover the whole city.

One hundred and sixty or seventy howitzers continued to bombard day and night for more than ten days, and the entire city of Guangxin was covered and had long been reduced to ruins.

There was hardly a complete house in sight, there was a fire burning everywhere, and the fire on the sea was still very vicious, and Bailiyan could only enter the city through the tunnels.

When he saw Jiang Gan, his face was pale, but he was not in a bad mood, after all, after more than ten days of fierce fighting, he sank and damaged nearly 30 enemy ships, and they were all ships of 20,000 or 30,000 stones, and what really made him very angry was the destruction of the Guangxin Mansion.

Guangxin Mansion has been passed on to him for the fourth generation, and there has never been any injury in the past hundred years, and now it was destroyed in the war overnight, which made him feel ashamed of his ancestors and ancestors.

That's not all, Guangxin, which was still the pearl of the North Sea half a year ago, turned into a ruin in only a few days, which made him even more heartbroken, and decades of hard work were in vain, which made him extremely sad.

"I've heard about the situation in Guangxin, but I didn't expect it to be so bad, the whole city is empty, and this loss is simply too great." Bai Liyan's tone was heavy, he was very sympathetic to Jiang Gan's feelings, but there was nothing he could do, this is war, and you have no choice in war.

At this time, Jiang Qian said

"The armpit ironclad ships of a mile outside the harbor are indestructible, do you have a good plan to break the enemy here?"

"That's why I'm here, I'm going to wait for Xuanyun's reinforcements to arrive and sink it by other means. In addition, there is one thing I was about to ask you, can Xue Sheng's 645 rapid-fire cannon use armor-piercing shells? ”

"I used it, but it had little effect, somehow, only a hole was drilled in the iron ship, but it did not cause an explosion, and dozens of consecutive rounds did not work at all, but it was counterattacked, and the losses were not small."
