Lu Ming and Wang Wencai began to look for materials to make sniper rifles at the free trading booths in the square.

Because of the relationship between the Rookie King Tournament, the trading market has become extremely lively, and during the period before the next battlefield starts, it has become the unanimous choice of all players to sell all the materials they don't need for money, and then buy the materials they need.

"How much does this cost with green vines?"

"10 copper coins!"

"I'll go, make no mistake, boss, this branch taken out of the woodland of the battlefield will be sold for 10 copper coins, why don't you grab it?"

Seeing that Lu Ming actually wanted to buy green vines, although Wang Wencai didn't know what to use, he still bargained directly with the boss.

"Little brother, you don't know, this vine is not something you can bring out if you want to, this is the material that was exploded by killing ordinary wild monsters, although I don't know what it is for, but it is a genuine material."

"Boss, you can also sit on the ground and start the price, 5 copper coins, don't sell it."

Wang Wencai saw that Lu Ming had the intention of paying money directly, so he hurriedly stopped Lu Ming, and finally the players in the stall sold the green vine 5 copper coins to Lu Ming.

"Brother Lu, aren't we purchasing materials for making 98K sniper rifles, I don't see any mechanical parts related to vines in the construction diagram."

"This is not a mechanical part, but its role can be no weaker than that of a mechanical part, and you will know when the time comes."

In the next time, after Lu Ming chose the materials, he asked Wang Wencai to bargain, and he only had to pay for it.

Wang Wencai was happy to be Lu Ming's bargaining expert, and almost every material had to be cut in half of the price from the players on the other side of the booth.

Even if he encounters some stubborn profiteers, this Wang Wencai can cut off a star and a half with a mouth.

After taking a big turn in the trading market, Lu Ming and Wang Wencai had already purchased the materials that they had determined at the beginning, because Wang Wencai had saved a lot of money by bargaining, and Lu Ming also bought some other things, which were materials that Wang Wencai couldn't understand like green vines.

"These are the small mechanical parts you need to make, you can buy the forging room separately and forge it, and when it's done, just come out and wait for me."

Lu Ming handed over most of the transmission machinery parts in the firearms, including the barrel and the chamber, to Wang Wencai for production.

"Don't worry, Brother Lu, you must make it exactly according to the drawings."

After Wan Wencai took the materials, he clicked a few times on the interface, and a water ripple portal appeared, and Wang Wencai stepped in.

Most of the materials Lu Ming held mainly involved the production of parts such as the body, buttstock, sniper scope, and muffler of the sniper rifle, which Lu Ming decided to build himself.

Slide your finger, select the life occupation site to buy in the game system interface that appears, and after pre-paying 1 silver coin, the water ripple appears, and Lu Ming enters the forging room with his backpack.

Although no parent or child has ever won 98k, in a chicken game in his hometown, Lu Ming has already kept every inch of 98k's skin firmly in his heart.

With his eyes closed, Lu Ming had a 98k spinning in the void in his mind, Lu Ming felt that the overall shape of 98k was compared to AKM, and he always felt that 98k looked like a slender sword as a whole, while AKM looked like a heavy sword.

"I still like heavy industry-style sniper rifles, so I'll give it an upgrade."

Lu Ming plans to change the body of the 98k gun, it looks so weak if he doesn't do a "thin sword", and he doesn't look silly if he doesn't do a "heavy sword".

Lu Ming took out the 5 pieces of high-quality ore he had obtained before, and began to smash them into the furnace to heat, "I hope that the 98k forged from this high-quality ore can withstand more thunder and lightning blessings!" ”

While the fine ore was heating, Lu Ming took the refiner's war hammer to polish the golden horn obtained by killing the golden bull, and the curved shape of this horn was just enough to make the butt of a sniper rifle.

Ding-ding-clang.

The golden horn was divided into two by Lu Ming, and the sharp position of the first half of the horn was put aside, and the second half was left by Lu Ming.

The golden horn is oval, which does not conform to the shape characteristics of the butt, so Lu Ming cut the horn from the middle position and divided it in two, and then cut a finger-wide strip from the edge of the cut golden horn to the inside.

When the two separate golden horns were cut off, Lu Ming reunited the polished two golden horns.

"Perfect! Break the Kote! ”

The fine ore in the furnace was already burned red, Lu Ming picked up the tongs and pinched out the ore, and then smashed the ore with a hammer.

On the other hand, Wang Wencai operated various machinery and equipment to process and produce various needed firearm parts given by Lu Ming, and the most tricky of these parts was the barrel, that is, rifling.

According to the impact force of the barrel described by Lu Ming, it is almost ten times or even higher than that of a normal firearm!

At present, Wang Wencai is using the A+ grade metal pipe with the highest strength provided by the game system, and he only uses B-grade pipe to make small forts.

"Brother Lu, I'm in trouble."

Lu Ming, who was forging the butt of the third section of the gun, received Wang Wencai's information, so he could only stop what he was doing and ask, "What's the problem?" ”

"Brother Lu, the quality of this gun, the most critical and difficult part to do is the barrel, don't look at the barrel is a long tube, just take that tube, it's not like this at all."

"The barrel needs to be able to withstand the impact of the air squeezing after the bullet explodes, and it must be able to withstand the huge heat caused by the high-speed rotation friction of the bullet, otherwise it will affect the trajectory of the bullet and degrade the accuracy of shooting."

"The rifling is even more critical, it is the rifling that needs to be pulled out of the barrel by squeezing, and it is best to add some tungsten ore when making it to ensure that the barrel does not bend after overheating."

Lu Ming had heard of the case of the rifle exploding after someone fired a gun, and there were also cases where the barrel of the gun was listed in the shape of a chrysanthemum after being shot, and now that it was his turn to make the gun, this became a roadblock.

"That's right, I remember!"

Lu Ming remembered that he had specifically looked for information on the production of guns before, and at that time he paid more attention to the design and production of the gun body. Just glanced at the barrel, that is, this casual glance, Lu Ming remembered the strongest and oldest production method for making the barrel!

Cutting method!

It is the oldest rifling method. This rifling processing method is to use a hook-shaped turning tool to stretch into the blank barrel, and cut out the gun wire little by little, and the cut out pipeline slowly forms a groove, and rotates the blank barrel in the process of picking, so that the groove maintains a certain rotation angle, so that the groove cut out becomes a female rifling.

The cutting method is very labor-intensive and time-consuming, and it does not allow mass production, so few people use this manufacturing method. However, this processing method has minimal damage to the metal structure of the barrel and is most suitable for machining high-precision barrels.

Lu Ming's favorite sniper rifle, codenamed "Eurostar", is made in this oldest way.

"Brother Lu, if the energy tolerance you require is 10 times or more than that of an ordinary machine gun, the A+ pipe I choose now is probably not good."

"Are there any S-grade or S+ pipes?"

"There is no material library provided by this system for the time being, and the highest is A+ grade."

Lu Ming thought about it, and asked Wang Wencai to make other firearm parts for the time being, and he was going to think of another way about the barrel material.
