The grades of alloys from low to high are: e-grade alloy, d-grade alloy, c-grade alloy, b-grade alloy, a-grade alloy, and s-grade alloy.

Starting from the C-grade alloy, it is necessary to add vibranium into it. The more vibranium accounts for the higher the strength of the alloy. For the strongest S-grade alloy, vibranium even directly becomes the main material. At the same time, other components need to be added.

A rarer metallic element.

It is precisely because of the rarity of vibrating gold that alloy weapons have been separated from ordinary iron since they were A-level and are called divine iron!

And weapons made with divine iron are naturally divine weapons! Divine weapons!

Chen Fei's heart was racing after seeing these introductions, and his boiling blood made him unable to calm down for a long time!

All these show that connecting with the interstellar world is the first step in the real sense of becoming stronger!

What excited Chen Fei was that there was a large piece of gold seismic ore lying in his storage space!

Although it has not been refined yet, such a large piece is enough to make many B-level alloy weapons and A-level alloy weapons.

What is the concept of holding a magical weapon in your hand?

Sparkling cheats!

Shining brightly!

Not too handsome at all!

"Sure enough! The guy who owns the system still has the aura of the protagonist!"

Chen Fei thought in his heart...

Although he knew that Zhenjin could be used to create magical weapons, Chen Fei did not have a clear concept!

Little did he know that his seismic gold ore was enough to trigger an interstellar war. Even though the grade of seismic gold was not a top-notch material, it was valuable because of its rarity.

Zhenjin only existed in large quantities in the ancient universe. At that time, there were hundreds of millions of living planets in the vast universe, and there were countless races. There were many powerful races that claimed to be gods!

Only during that period could vibrate metal be widely used in the forging of weapons.

To give the most intuitive example, you only need to add a few tenths of a milligram of seismic gold to a C-level alloy weapon. With this amount of seismic gold, the weapon will undergo a qualitative change, but without it, it will be a D-level alloy weapon.

And those few milligrams are equivalent to a little powder scraped from an artifact, which is enough to show the rarity of vibrating gold.

Chen Fei confirmed that the materials he collected were enough to mass-produce E-level alloy weapons. Some D-level alloy weapons could also be manufactured. This was mainly because there were only a few pieces of kryptonite in his material space, although krypton was in D-level alloy weapons.

It accounts for a very small proportion in the alloy, but it is extremely important and cannot be ignored or replaced at all.

But does Chen You plan to mass-produce and become an apocalyptic weapons dealer? It would be enough to be able to produce D-class alloy weapons that satisfy the needs of survival team members!

If a person has a weapon that can connect with the stars, he will not be at a disadvantage in a battle with alien visitors.

Because there were not many materials, Chen Fei did not rush to make them right away. In addition, he could only confirm his needs for use now, and in his hands was the transformable weapon of the Gaia Star Warrior.

According to the weapon rating of the arsenal, the material of this weapon is higher than that of D-grade alloy weapons, but it does not meet the standards of C-grade alloy weapons because it lacks the vital material of vibranium.

This makes it unnecessary for Chen Fei to make another D-grade alloy long knife, unless he has any special weapon needs.

As for other people's weapons, since Chen Fei has the conditions, he is ready to tailor them for everyone.

For example, Wu Gang has good strength after becoming an evolver. Making a long knife for him requires a relative increase in weight, so that he can better exert his cutting power and make full use of his strength advantage.

As for women like Nangong Jin, Mu Meiqing and Wang Yuanyuan, they are on the weaker side in terms of strength, so they need their weapons to be as light as possible and the blades to be made thinner to increase their use from another angle.

The destructive power of the long knife cuts while reducing the consumption of physical energy.

Chen Fei exited the detailed interface of knife weapon production with unfinished content. Even if he did not enter the detailed interface of other weapons, Chen Fei knew that the overall production would not be too different, and would basically be the same production mode.

What surprised Chen Fei a little was that war hammers and battle axes were at the top of the production rankings of interstellar weapons, while long knives were only ranked in the middle. As for long swords and long spears, they were at the bottom!

If some great swordsmen in ancient times knew about this, they would be so angry that they would crawl out of their graves to rectify the name of the long sword!

After knowing that the most popular interstellar weapons were war hammers and battle axes, Chen Fei thought about it for a moment and felt relieved. He could see some clues from the attribute points of interstellar standards.

What those alien races are best at is strength! And the ones that can give full play to their strength advantage are naturally heavy weapons such as warhammers and battleaxes. That’s why long swords that tend to be more technical are not popular and will have to sit on the bench for a long time.

This is understandable.

After Chen Fei exited these cold weapon production pages, he entered the main interface for the production of firearms and ammunition.

At this stage, Chen Fei has only unlocked the production of basic firearms, bullets and ammunition on Earth. As for more high-end, powerful and technologically advanced interstellar weapons, they require at least the third level of the arsenal to produce.

In the firearms catalog, Chen Fei saw various types of firearms, from pistols to sniper rifles, and even the powerful anti-tank sniper rifle in Chen Fei's hand.

However, what is helpless is that due to its own weight, the anti-tank sniper rifle can only be used by others except for powerful people like Chen Fei and Wu Gang for fixed-point shooting, completely losing its mobility and even requiring special protection.

This is not suitable for shuttle battles among zombie groups, but it can be used to its greatest effect in battles guarding positions at specific locations. It only requires a sniper point and sufficient bullets.

After having the arsenal, the safe zone has no value to Chen Fei. He can be self-sufficient in everything, and even do better than the safe zone.

After returning to the safe zone this time, Chen Fei planned to try to contact Li Zhenbei again to see if he could get a map. No matter what the final result was, he had to prepare to leave the safe zone.

This mission allowed Chen Fei to collect enough building materials to further expand and improve the construction of the camp, so that the camp can meet the basic requirements for use at this stage. It only lacks a wind turbine to complete the power system.

…

Next, comes the main event!

Chen Fei felt both expectant and anxious as he exited the main page of the firearms and ammunition production function, and then entered the corresponding production item column of the arsenal.

At this time, in the first grid of the inventory, there is a red scroll icon with a big question mark on it and an x2 number in the upper right corner.

These are the two interstellar equipment design drawings presented by Chen Fei’s generous system father after he successfully started the arsenal function!

In Chen Fei's understanding, interstellar equipment is at the same level as Gaia planet warrior equipment, and they are all things that Chen Fei's arsenal level cannot produce at the moment.

But if there are blueprints, Chen Fei can unlock and make two pieces of interstellar equipment in advance. If he is lucky, the blueprints of weapons like laser guns will be randomly produced. After they are produced, each member of the survival team will have one. Then the survival team will have one at this stage.

The strength to push everything!

Chen Fei took a deep breath. He was afraid that he would use up all his character because he had the bloodline of the strongest master in the universe. He prayed a few random words in his heart, and Chen Fei silently chanted and used it.

Almost as soon as Chen Fei's thoughts reached his mind, the scroll icon suddenly shattered and turned into small icons with names that flashed quickly in front of Chen Fei.

Chen Fei only felt that his eyes were dazzled and he could not see anything clearly. After all the icons disappeared, a huge icon appeared directly in front of his sight.

The round items are equipped with eye-catching red characters!!!

Multifunctional interstellar tactical helmet

helmet???

Holy shit!!!

As soon as Chen Fei saw the word "helmet", he thought "mmp" in his heart.

Although the combat uniform he made lacks a helmet, this thing is currently dispensable and can be replaced by the soldiers' camouflage helmets.

As a result, a drawing that may randomly produce powerful weapons resulted in a painless interstellar tactical helmet that has no obvious effect on improving combat effectiveness!

Even if the word "interstellar" enhances the quality of this helmet, after all, its essence is just a helmet!
