Yi Fei immediately took all the 2,000 pieces of refined iron ore in the trading bank, and then seconds a group of inferior fuel materials.

Refined iron ore is also two parts of melting, the time becomes ten minutes, each melting part has five points of experience, he melted these two thousand parts of refined iron ore, and the level has risen to eleven levels.

With the iron ingot, the first thing he did was make an improvised revolver, which was taken out of his blood by a shark yesterday, which was simply miserable.

The improvised revolver required one hundred and twenty-five iron ingots, twenty-five parts cloth, one metal tube, iron ingots and cloth were ready-made, just wait for the metal tube.

The metal pipe is composed of five parts of iron ore concentrate and thirty parts of mechanical parts, the synthesis time is half an hour, and the experience is twenty points. Yi Fei second out of the metal tube, directly transferred to the synthesis of a simple revolver, and the revolver that originally took twenty-four hours to make appeared in the backpack in the blink of an eye.

Yi Fei took out this simple revolver from his backpack, which was just an ordinary version, and immediately wanted to complain. The welds are rough, the magazines are pitted, and the doors feel asymmetrical. The handle is wrapped in linen cloth and feels slightly heavy to the touch.

"It's really a simple version...... Yi Fei felt that this gun would explode at any time.

Simple Revolver [Normal]: A shoddy revolver with low damage and a slow rate of fire, and the advantage is that it is not a pity to throw it away.

Damage: 60

Range: 20 meters

Ammunition: 6 rounds/9mm pistol, submachine gun rounds

Rate of fire: 83

Stability factor: 133

Reload speed: 140

Durability: 100 (unopened)

This revolver gives a hundred experience points, and now there is still no ammunition to make. He opened the furnace and stuffed the wood and the sulfur ore he had purchased earlier, and in a few moments he got five sets of charcoal and five sets of sulfur powder, which took five seconds each, and there was no experience gain.

Then it was synthesized by an intermediate workbench, and one gunpowder consumed thirty parts of charcoal and twenty parts of sulfur powder, and five groups could only make sixteen parts. This one takes two minutes, one plus a little experience.

With gunpowder, the next thing was simple, a nine-mm pistol submachine gun had thirty rounds of ammunition, ten iron ingots, five gunpowder, and ten minutes. It only took Yi Fei a minute to get 90 rounds of ammunition after completing these procedures.

With a bullet in the backpack, Yi Fei walked out of the studio with a simple revolver, every boy has an innate desire for firearms in his heart, and the pleasure of shooting is probably similar to the shape of multiplication.

This simple revolver does not have a special drum, it can only be loaded one shot at a time, Yi Fei loaded six bullets, learned the plot in the film and television drama, broke his fingers, and the drum spun up and down, and then flicked it, clicked, and stuck into the magazine.

"Don't lie to me......"

Yi Fei placed six coconuts at a distance of ten meters, and then aimed at the target.

Bang!

Ouch!

There was a crisp sound, and the firelight erupted at the same time along with the gunsmoke, and Yi Fei didn't have time to see if he hit the target, so he directly threw away the pistol and shouted with his hand.

He didn't know what that stability factor meant, and because he was lax in his grip on the gun, the recoil when the revolver fired immediately shook his mouth, and he subconsciously threw the gun away.

"It's such a big recoil...... What about the cheat? ”

Yi Fei rubbed it for a long time and picked up the gun again, he didn't know where the bullet hit just now, and sure enough, he didn't have much experience in handjob for the first time......

This time, Yi Fei learned his lesson, clenched the handle of the gun with both hands, and moved the front sight slightly downward.

Bang!

This time, the bullet directly opened the scoop of the coconut, and the juice splashed everywhere.

Yi Fei was quite satisfied with the gun, and believed that with more practice, he should be more proficient. He opened the crafting table, intending to upgrade the improvised revolver recipe to the maximum level.

It takes a lot of experience to upgrade the weapon and equipment formula, and it takes 500 points to upgrade to Excellent, 1,000 points to Excellent, and 2,000 points to Perfect. Yesterday, he saved 3,200 points of formula experience in the development of the formula, and now it is still almost, and he casually developed a few times to perfect the simple revolver.

The number of bullets for the perfect improvised revolver has not changed, the damage has increased from 60 to 80, the effective range has increased to 30 meters, and more importantly, the stability factor has increased from 133 to 145, although I can't understand the expression of this factor. But I think the recoil has weakened, so it can't be increased.

Crafting the perfect firearm also doesn't add material or time, and can be of any quality. Yi Fei calculated the cost of the improvised revolver, which was about 19 silver shells. Now a group of charcoal and a set of sulfur powder are 600 parts, the price is 3 silver shells, and each group can make 20 parts of gunpowder.

The unit price of gunpowder to make a nine-millimeter bullet is 1.5 silver shells, plus the cost of iron ingots is 1.2 silver shells, which is basically equivalent to a group of 30 bullets for three silver shells.

"A revolver with a golden shell, a group of bullets and five silver shells."

Yi Fei happily decided the price of the first weapon on the whole network, and he planned to sell the following three qualities at the same time, an ordinary one gold shell, an excellent one hardware shell, and an excellent two gold shellfish, with the highest cost profit margin of 900 percent.

Yi Fei quickly hung out ten guns of each quality at one time, and hung three hundred sets of ammunition at the same time. Almost every time it is put on the shelves for a few seconds, it is swept away, there is no way, the player base is over 100 million, and the number of eyes staring at the trading line cannot be counted, and there are many rich people.

After deducting ten percent of the tax, Yi Fei got forty gold shells, which was already more than his rent for this month, and it only took him a few minutes.

For safety reasons, he only plans to sell two batches of sixty handfuls a day, and he puts the rest of the money on new tools.

Fine iron axe, this is a fine iron axe with up to 800 durability, the formula cannot be upgraded, and it can be done by cutting trees and mining twice, but the durability is basically cutting a tree and dropping a little, all compared to the iron axe, the wear resistance is much worse.

However, saving sixty percent of the effort and time will definitely make the local tyrant players rush to it, he opened the workbench, the formula of the fine iron axe requires three materials, two parts of the fine iron ingot, five parts of the blade, and one part of the metal pipe.

The material price of the fine iron axe is much higher than that of the iron axe, and the production time is also very long, the blade requires 30 iron ingots and 15 mechanical parts, and the production time is 10 minutes. In this way, it takes an hour and a half to process materials, and it takes five hours to synthesize a fine iron axe, and it is gone in half a day, but the experience of a fine iron axe is on top of a simple revolver, and the system rewards seventy points of experience.

Yi Fei tried to do it, and the level was increased again, and the simple revolver was almost upgraded before.

The cost of a fine iron axe is between fourteen and fifteen silver shells, and he feels that this fine iron axe can be made in large quantities, after all, it takes only a quarter of the time of a revolver.

So he decided to use the iron axe and revolver as the main income in the next week, and the fine iron axe priced at fifty silver coins would cut down wood worth one hundred and fifty silver shells even if all of it was used to cut down trees.

With these things done, Yi Fei set out to strengthen his home, and the roller shutter doors and iron guardrails brushed out of the intermediate workbench were additional facilities to the building structure.

The roller shutter door requires 300 iron ingots and 3 mechanical gears, which are made of 50 iron ingots and 65 mechanical parts, and take 24 hours to replace the double door, with a durability of up to 10,000 points, and a 20% weakening effect on pistol and submachine gun damage.

Yi Fei quickly came out in two seconds, then removed the single door from the living room and studio, replaced it with a double door, and then upgraded it to a roller shutter door. After removing the single door, Yi Fei had to remake two combination locks and install them.

The opening of the roller shutter door is not as convenient as that of a wooden door, but it must be very strong in terms of defense after leaving the island.

Iron guardrail is an additional facility installed on the window, which is equivalent to an anti-theft window, and the durability of the wall with doors and windows is half of that of the ordinary wall. Iron guardrails only cost twenty-five iron ingots, and can be made in an hour, which is absolutely inexpensive.

Looking at the upgraded two houses, Yi Fei felt a lot more at ease, and then he went on to make several large storage boxes, weapon storage boxes and put them in the studio with shelves. Recently, he has to take advantage of the mechanical parts, electronic components and fine iron ingots before the price skyrockets to buy a large number of supplies.
