At present, the barrels used in the industrial park for Type 2 rifles, Type 2A rifles and light machine guns are all rolled out of seamless steel pipes by grading and rolling, and after the power provided by the magic motive, the length of this steel pipe has also been quite extended, and it is no longer limited by water power as before, and can only be rolled into a standard seamless tube of 1000 lengths.

However, there is still a big problem in the military application of such steel pipes, that is, there is no rifling. A rifle without rifling can at best maintain its lethality at a range of one hundred to one hundred and fifty meters, and once rifled and evolves from a smoothbore gun to a rifled gun, then this range of destruction quickly expands by two to three times.

This is because when the bullet is fired in the rifled barrel, it will rotate along the rifling, and after the rifling is discharged, the bullet will have an extra angular momentum of rotation, and the rotation speed can reach thousands or even tens of thousands per second.

What Xia Lin wanted was to update the equipment of the gun factory, and change the equipment currently used for barrel rolling to the cold forging and gun drilling equipment commonly used in the previous life.

Cold forging equipment needs to consider stability and accuracy, for the rifled gun barrel this precision instrument, an error of 0.1 will lead to a decrease in the air tightness of the rifle, which will lead to a significant decrease in power and shooting accuracy, Xia Lin needs to integrate all the technical forces on hand in the industrial park to carry out the research and development and manufacturing of this kind of cold forging equipment.

As for the important gun drill equipment in the barrel processing equipment, it is easier for Xia Lin to solve, with the metal of the gods such as pure gold, it is not a problem to have a gun drill that is super long and requires great rigidity and strength, but the gun drill is different from the machine tool bit, and the accuracy requirements are higher, and Xia Lin does not know if Master Holguin can use fine gold to process a suitable gun drill.

After returning home with the relevant materials and carefully consulting, Xia Lin felt that with the current level of technology at hand, it should not be a problem to manufacture suitable cold forging equipment, but it may require the dwarf masters of the machine tool factory to spend a considerable period of time manually polishing and improving the accuracy of the equipment manufactured.

However, the next morning, Xia Lin came to the machine tool factory, and when he consulted Master Holguin, he encountered a small problem.

"Boy Xia Lin, if your request is only what is shown on the drawings, with the refined gold smelting technology I have mastered, it is completely possible, but if you need ten spear drills, do you really have enough funds on hand?"

In the factory director's room, which was deliberately planned to be handed over to the dwarven masters, wrapped in a thick felt blanket, Master Holguin, who was sitting by the window basking in the sun while holding a wine jug, looked at the gun drill drawings handed to him by Xia Lin, and asked with some surprise.

"Master Holguin, just tell me how many gold lunds these ten spear drills need! This equipment is related to the power of the rifles in the hands of our new army, and I will not hesitate to invest in it, even if it costs a lot!"

When Xia Lin put forward the request, he also made a preliminary estimate of the cost of these ten gun drills, a gun drill weighs at least two kilograms, according to the price of 94 gold lunent a pound, 263 gold lunent a kilogram of fine gold, that is, almost 500 gold lunent a gun drill, ten is 5,000 gold lund, which is more huge than the investment of many factories in the industrial park.

….

Seeing this, Master Holguin lowered his head and stroked his beard, and after a moment of silence, he said a number that made Xia Lin's heart tremble:

"According to your requirements, the specifications of these gun drills are all 1.5, so I preliminarily estimate that each gun drill will probably cost about 3.5 kilograms of fine gold, and the cost of other materials for one-time processing will be cheaper, about 10,000 gold lund, I can give you what you want!"

Speaking of which, the guys from the Hellgana Alchemist's Guild may not be able to take out so much, you kid is the right person, I still have some channels at hand, I should be able to buy so many pure gold raw materials for you!"

"Shhh Ten thousand gold lundes?"

Even if he was mentally prepared in advance, Xia Lin was frightened by the price that came out of Master Holguin's mouth that doubled his estimate, although the industrial park he founded single-handedly relied on various new products, and it could be called a daily profit

, but it is not easy to scrape together 10,000 gold lundes.

According to the current rate of about two hundred gold lunt dividends per day of the New Leaf Chamber of Commerce, it will take Xia Lin fifty days to collect this money.

"What? Didn't you just swear by it? Is it impossible to get the money? I'm sure I'll have to wait for your money to come up before I can buy it, and if it is processed in installments, the alchemy potion and the magic circle will need to be rearranged, and there will probably be an additional processing fee of a few hundred gold lundes."

Seeing Xia Lin's embarrassed look, Master Holguin took a leisurely sip of wine and smacked his lips.

"No, I'll get this money together as soon as possible, and I hope Master Holguin will contact those channels first, so that they can get the Adamantite we need ready."

Xia Lin thought about it for a moment, and felt that according to his plan, there should still be some possibility to scrape together the money in a short time, so he gritted his teeth and asked Master Holguin to let it go.

"You guy...... It's really a special human being, those big nobles and big businessmen who earn gold lunt are eager to build a few more manors and buy a few more slave girls, but you are the only one who desperately invests money in this industrial park.

Forget it, for the sake of your purpose and the taste of our dwarves, if you are really difficult, I can deal with those alchemy maniacs with my old face, and give you a chance to pay for the purchase of sperm in installments, but the first gold lunt, at least 5,000 yuan will be given to me before I have the confidence to negotiate with them!"

Master Holguin saw Xia Lin's determined look, his face showed a slight surprise, 10,000 gold lunt was also a lot of money for a grandmaster-level blacksmith like him, who was highly valued by the empire, and the decision made by Xia Lin couldn't help but make Master Holguin shake his head and say with a sigh.

"Really? Then please Master Holguin, 10,000 gold lunds is indeed a bit difficult for me to come up with, and I will gather no less than 5,000 gold lunds and deliver them to you as soon as possible!"

Xia Lin didn't expect Master Holguin to be willing to vouch for himself, so he immediately agreed decisively. Even if 10,000 gold lunt was raised according to Xia Lin's plan, it would make the current Xinye Chamber of Commerce hurt, but 5,000 gold lunt would not be a big problem, and the plan he originally made was aimed at this goal.
