According to the equipment situation, all kinds of lathes, planers, and milling machines are completely at the level of modern medium-sized arsenals, and there are even two five-axis linkage CNC machine tools, one horizontal and one gantry; One five-axis linkage milling machine and one large boring and milling machine.

"It's a pity that bullets and shells can't be made, and there are only more than 10,000 tons of steel, otherwise it's no problem to build machine guns and cannons for you." Cao Jiawen said confidently.

"Can't be made with bullets and shells? What are the main obstacles? Lin Xiao asked confusedly.

"In this era, smokeless gunpowder can't be made, and all the people used in the world are black powder."

Cao Jiawen replied regretfully.

"Smokeless gunpowder? Nitroglycerin? Lin Xiao, who was proficient in firearms, reacted immediately.

"That's right, I found some finished products in the container, but there are not many of them, and I am reluctant to use them, so I still have to find a way to produce them myself, to make this thing, it's not that there is no way, but it depends on Lao Zhou."

Cao Jiawen looked in the direction of Fangcheng Town and said: "Lao Zhou has not been idle in the past few days, and is taking people to inspect the address of the hydropower station dam and the address of his chemical plant and steel mill in the upper reaches of the Fangcheng River. ”

"Hydroelectric power station? Is it? That's great, if the hydropower plant is built, then we can build the world's first industrial center here, right? Lin Xiao was overjoyed.

"That's not it, relying on the diesel generator on the Lufeng ship is not a long-term solution, how long can those tens of thousands of tons of diesel last."

"That'...... Lao Cao, in your opinion, what kind of gun should be the most suitable for the current one? ”

"At present, since we can only use black powder, let's produce a little flintlock pistol, the structure of the thing is simple, our barrel is made of special steel, plus our processing accuracy, to ensure that it is farther than the most advanced flintlock pistol."

The flintlock pistol Lin Xiao knew, it was still a breech gun, the firing procedure was cumbersome, and it could only be fired once every two or three minutes, but it was much more advanced than the arquebus commonly used by the Ming army at present.

Lin Xiao saw the arquebus equipped on a large scale by the Qing army and the Ming army, this kind of gun did not even have a trigger, that is, after aiming, the fire rope was stuffed into the fire door to ignite the gunpowder, and then the lead pellet in the chamber of the gun was fired, not only the range was only about 100 meters, but also there was no accuracy at all, when the battle was all carried out by a large number of musketeers, relying on dense firepower to cause surface killing, this method of warfare was introduced to China by the Francophone man, commonly known as "platoon gun tactics", and then it was popular in Europe for more than 200 years, until the use of the breech gun with fixed charge came out before inventing new tactics.

Because of the need to carry a long rope, not only can it not be fought on a rainy day, but even on a sunny day, it is very inconvenient to fight in the field, and the French army once ridiculed: "Carry a mile long rope and fight for a day." ”

The flintlock pistol does not need a fire rope, only a hammer with flint is installed behind the fire door, and an anvil iron is installed above the fire door, when firing, a trigger is pulled, and the hammer is pressed down to hit the anvil iron to send out a spark, which can ignite the gunpowder in the fire door, and the shooter can take aim calmly, which greatly increases the accuracy.

"And what about the cannon?" Lin Xiao continued to ask.

"Due to the problem of shells, the breech cannon has also been built, and the structure is the same as that of the Hongyi cannon, just with our steel level, we can kill all the same type of artillery in seconds."

Sun Lei, who was pondering a set of machine tools, came over and answered.

Hongyi cannon, also from the Francophone man, due to the cast iron level is not good, the original Ming Dynasty used various types of artillery are either light but too close in range, or a little longer range but heavy guns. Since the Hongyi cannon was introduced into China, its range of enough to reach two or three miles away made the Ming army very fond, so a large number of imitations, called "Hongyi cannon", "general cannon", had made a significant contribution in the early stage of the battle against Nurhachi Houjin, after the defection of Kong Youde and others, some artillery-making craftsmen flowed into Houjin, so the Houjin troops also copied a large number of them, and because of the avoidance and changed the name of "red-clothed cannon".

However, due to the backwardness of China's overall iron casting technology, there are inevitably many sand holes inside the barrel, and the gun wall is too thin if it is easy to explode, so the red-coated cannon is generally heavy, weighing thousands of catties, and the heaviest is more than 10,000 catties, which is inconvenient to transport, and is mostly used for urban defense, and is rarely used for field battles.

Now Cao Jiawen and they use ready-made special artillery steel cannons, not only the range can kill the same kind in seconds, but also the weight can be greatly reduced, Cao Jiawen is very confident to create a steel cannon of 1,000 catties, the range of which is far more than 10,000 catties of red-coated cannons.

"However, steel is limited, no matter the guns, we can only make them in small quantities, these good steels are treasures, and I have to keep them for a big use in the future." Cao Jiawen said with a wry smile.

"Good...... It's enough to make 3,000 flintlock pistols, cannons...... It is enough to build thirty or fifty doors, and as long as Lao Zhou's steelmaking plant is built in the future, we will use his steel, which is enough to be called black technology in this era. Lin Xiao responded diligently.

"Also, you talk to Lao Chen, give me a few more of his seamen, we only have me and Sun Gong who understand machinery here for the time being, and Sun Gong is still a temporary cameo, we must train some technical backbones as soon as possible, this can only be done by modern people who have crossed over." Cao Jiawen pointed at Sun Lei and smiled bitterly.

"Okay, I'll go and tell him that sending a few of these young people to the arsenal for a long time is a long-term plan, and Lao Chen will definitely support it."

"Team Lin, I have a request,"

Seeing that Lin Xiao was about to leave, Sun Lei hurriedly stopped him and said:

"Captain Chen said that we are going to build a shipyard over there in Qisha Town? Can you let me go there, I'm interested in warships, and when I can use the car later, I'll come back and do the maintenance logistics for you? ”

"Yes, Team Lin, Xiao Sun's hobby is to study all kinds of modern warships, and he has a complete set of famous battleship drawings since the Age of Discovery." Cao Jiawen lost no time in helping out.

"Really? That's great, last time Lao Chen was anxious about not being able to build a big ship like a unicorn in China for the time being, it's all my fault, why did you forget to brainstorm? Lin Xiao said overjoyed.

"This is also to blame me, last time Lu Hua proposed that everyone collect the information for safekeeping, I just handed in the professional information of vehicle walking, and forgot my hobby." Sun Lei said embarrassedly.

"Hehe, that's good, I'll go to Lao Chen right away and settle this matter as soon as possible."

Then Lin Xiao said goodbye and left, he was going to the Dadun Cave Warehouse to see how many treasures he had in his hands, Sun Lei said that Lu Hua was still sorting out the final list.

……

When Lu Hua smiled and put the list of weapons and materials in front of Lin Xiao, Lin Xiao was squinting and looking at the large and small crates stacked in the warehouse with great interest, which were divided into several areas in the brightly lit cave.

"Hey, do you want to see it?" Lu Hua's eyes were gloomy, and he said angrily.

"Oh, yes, yes."

Lin Xiao turned his head and reached out to take a stack of papers, but quickly glanced at Lu Hua in front of him, "Ah, why haven't you seen you for a few days, our Engineer Lu is getting more and more standard......"

"Go, go, go, don't spray maggots!"

Lu Huajiao took a sip, gave a white eye, and then said angrily: "Take a good look at your belongings, you have made a fortune." ”

"Oh."

Lin Xiao was a little embarrassed, his face turned red, and he hurriedly took the list in a panic and looked at it.
