At dinner, due to the completion of the crafting of the 17 defensive wooden fences adjacent to the second round, the basic requirements for improving the level of the crafting function have been met, and the crafting function is automatically upgraded to the second level, along with the inventory and material space under the crafting function.

Hearing the prompt at the end of the day, Chen Fei couldn't wait to enter the main interface of the production function to check it when he was eating, and in the eyes of others, he was holding the rice bowl in a daze.

After the second level of the production function, the production of thickened bulletproof steel plates and spears was successfully opened, these two are particularly practical things that Chen Fei is looking forward to, when Chen Fei saw it before, he only felt that thickened bulletproof steel plates had an important role, but even if they could be made, it was a little difficult to use them immediately.

However, now it is different, the team has newly included He Guantao and Zhou Fa, a simple duo with brains, with their ability to repair and modify cars, as long as they have this kind of good thing, they can use it reasonably in the first time.

Although the two pickup trucks are now modified with thick steel plates, these steel plates are only ordinary steel plates after all, which is the section of Wutong Road, because of the constant impact on those zombies, and now the steel plates have become potholes.

But there is one point that cannot be ignored now, because of the appearance of airdrop supply boxes, the official and military put guns into the distribution of normal supplies, which leads to the survivors who can get out of the city in the future, basically have some guns and ammunition in their hands.

Although the combat ability and survival ability of the survivors have been improved due to the upgrading of equipment, the relative ambition and danger (xìng) have also been improved!

The survivor who was originally honest and responsible will have a huge change in the (xìng) grid because of the power he had before, and even because the degree of change in the (xìng) grid in the last days (xìng) grid is equivalent to a different person.

At this time, although the main danger in the city still comes from zombies, you also need to watch out for other survivors.

And once out of the city, the other survivors will become the main danger, because the threat of the survivors is the most dangerous and direct because of the guns!

Whether it's snatching each other, or actively attacking and passively counterattacking, as long as the two survivors go to war, then there will inevitably be casualties.

Therefore, the newly unlocked thickened bulletproof steel plate after making level 2 is undoubtedly equivalent to a timely rain to the dry earth at this time.

Since the production is made of thickened bulletproof steel plates, the ability to resist bullets and impacts is not much, so that in the battle with other survivors, Chen Fei and they have a safer guarantee than other survivors! This is based on capital!

The newly unlocked spear is far less important than the thickened bulletproof steel plate, but it is also something that can be used immediately after crafting.

He Guantao and Ah Fa's new additions, in addition to the maintenance and modification of regular vehicles, they will definitely join the battle in some crisis situations, so the issue of the distribution of combat equipment between the two of them also needs Chen Fei's careful consideration, but obviously this simple-brained duo is only very reliable when repairing and modifying cars, and in normal situations, they are always in a situation where their brains are off the line, and it is really dangerous to share a weapon like a pistol with them!

Therefore, Chen Fei gave the military stabbing dagger to the two of them and used it as Errao's main weapon, but considering that everyone in the team had guns and the two of them had nothing, Chen Fei also assigned each of them a Type 54 pistol, but for everyone's safety, they were not assigned bullets, and the gun was hung on (shēn) just to let them pretend.

Chen Fei gave them a total of four military thorns in the airdrop material box, and He Guantao and Zhou Fa imitated Nangong Jin and pinned a military spur to the belt Zheng around their waists

In order to be handsome, the two of them asked Chen Fei for a whole gun (tào), a belt and leggings, but the whole (shēn) was just a pistol and a military thorn.

As for the other military thorn, it was welded to one end of the steel bar by them, and the general thorn was transformed into a long spear, both of them had seen the ferocity and madness of zombies, and they naturally felt that it was safest to keep enough distance from zombies, and melee combat was absolutely impossible for the two of them!

Chen Fei also felt that a long weapon like a spear was very suitable for this simple-brained duo, and with the defensive wooden fence, it could basically be output without scruples, which was completely foolish and brainless and highly efficient and low-risk.

But when Chen Fei saw the materials needed to make thickened bulletproof steel plates, it felt like a basin of ice water had been poured on him.

The material required to make a spear is very simple, that is, the most basic pig iron block, of course, this iron is also the main material of thickened bulletproof steel plate, but unlike the manufacture of spears, in addition to the production of pig iron thickened bulletproof steel plate, four other metal raw materials are also needed, although the proportion is very small, but no matter which one is missing, it is impossible to make thickened bulletproof steel plate, all of which are indispensable!

Chen Fei originally thought that the material needed to make thickened bulletproof steel plates was nothing more than steel, but after asking the intelligent voice system Momo, Chen Fei was embarrassed to find his ignorance, because white steel is iron, and it is smelted from pig iron.

In the very official answer of the end, steel is a general term for an iron-carbon alloy with a mass percentage of carbon between 0.02% and 2.11%, and it becomes stainless steel when a certain specification of chromium is added.

However, Chen Fei also found one point, that is, it was mentioned in the remarks of consumable materials that metal ore without metal raw materials can also be used, which means that the manufacturing system directly ignores the process of smelting!

According to the introduction of the end of the world, the thickened bulletproof steel plate manufactured by the manufacturing function is a more cutting-edge technology that cannot be achieved by the earth's military manufacturing!

Although it is also a bulletproof steel plate, the steel plate manufactured by the system is far beyond the current national military specifications in terms of hardness, impact strength, elongation, and other aspects of the bulletproof steel plate.

After understanding these relevant information, Chen Fei can understand the rare metals that need to be added to make thickened bulletproof steel plates.

It's just that he sighed in his heart that as the system functions become more and more powerful, more and more functions are unlocked, and there will be more and more things he needs to do (qíng) to look for!

Really! If you want to live a salted fish, you can become stronger, even if you have a system, you can't do it!

But this is something that there is no way (qíng), in order to become stronger, in order to survive in the last days, Chen Fei knows that he must do it if he wants to break his legs.

After adjusting the complex (qíng) thread, Chen Fei glanced at the inventory and material space that had been upgraded along with the manufacturing function.

This upgrade has increased the inventory by ten slots, but now only the first slot has something in the inventory, and the icon for the defensive wooden fence has the word 33 on it.

For the same item, the upper limit of the capacity of each slot in the inventory is 99, and if the number exceeds this, it will be automatically put into another slot, Chen Fei feels that it is very difficult for him to fill the entire inventory slot, or it can be very long, but fortunately, he doesn't need to think too much about this, just let it be.

What really surprised Chen Fei was the improvement of the material space!

This increase in material space has surpassed Chen Fei's inherent idea of doubling the space.

After the upgrade, the material space has been directly changed from a three-meter by three-meter nine-square-meter specification to a three-meter-by-ten-meter thirty-square-meter specification, and the height has also been increased to five meters.

Chen Fei thinks that this is very likely to be a very human adjustment made by the system according to the fact that most of the logs in the wood processing factory are seven or eight meters long, which is indeed a happy thing (qíng).

After dinner, He Guantao and Zhou Fa began to use the remaining materials to carry out basic modifications to the maintenance car, mainly the window welding steel reinforcement defense reinforcement, and then used the remaining steel plate to strengthen the door and some serious impact parts of the compartment body, as if patched, although it did not look beautiful.

As for Nangong Jin, Mu Meiqing and Wang Yuanyuan, the three girls returned to the office building to wash and apply masks after patrolling together.

Chen Fei didn't see any sense of the end of the world from the third woman's (shēn), and if this made the other surviving teams see it, they would definitely complain:

"Holy! Are you serious? Boss, this is the end of the world! ”

"Look at the women in our team, all of them are gray and have chapped skin, you are looking at the women in your team, is this Nima going to participate in the beauty pageant of the last days?"

"Big brother! This is the last days, alas! Can you be serious, how can the end of the world be if it is not miserable, how can it be the end of the world if it is not hard, let's have two channels at all, we are surviving in the last days and you should go to the Universal Travel Channel next door! Depend on! ”

“......”

In fact, Chen Fei felt that in the tense atmosphere of the last days, he used the envious, jealous and hateful eyes of others to delight his own taste........ It's just cool!

When the other party's eyes were red and jealous and he wanted to do it, he found out again..... The special equipment and combat effectiveness will be crushed!

At that time, he could be very dragged and hung up:

"I just like to see you unhappy!"
