While having dinner, because I completed the second round of making 17 defensive wooden fences, I met the basic requirements for upgrading the level of the production function. The production function was automatically upgraded to Level 2. The same upgrade also included the inventory under the production function and

material space.

After hearing Mo Mo's prompt, Chen Fei couldn't wait to enter the main interface of the production function while eating. To others, he looked like he was in a daze holding his rice bowl.

After the production function level two, the production of thickened bulletproof steel plates and spears was successfully started. These two are particularly practical things that Chen Fei is looking forward to. When Chen Fei saw it before, he only thought that thickened bulletproof steel plates played an important role, but

Even if it can be produced and used immediately, it is still difficult.

However, it is different now. The simple-brained duo of He Guantao and Zhou Fa are newly added to the team. With their ability to repair and modify cars, as long as such good things are available, they can be used reasonably at the first time.

Although the two pickup trucks are now modified with thick steel plates, these steel plates are just ordinary steel plates after all. In this section of Wutong Road, because of the constant collision with the zombies, the steel plates have now become bumpy. Fortunately, in general

The protection ability has not been reduced much, and with He Guantao and Zhou Fa still around, there is no need to worry too much about vehicle problems.

But one thing cannot be ignored now. Because of the emergence of airdrop supply boxes, the government and the military have invested guns in the distribution of normal supplies. This will lead to survivors who can get out of the city in the future. Basically, they will have whatever they have in their hands.

Some guns and ammunition.

Although the survivors' combat ability and survival ability have been improved due to the upgrade of equipment, their relative ambition and danger have also been improved!

The originally honest survivor will have a huge change in personality because he has gained the power he never had before, and even the change in personality in the end of the world is equivalent to a different person.

Although the main danger in the city at this time still comes from zombies, you also need to be careful of other survivors.

Once out of the city, other survivors will become the main danger. Because of the guns, the mutual threat between survivors is the most dangerous and direct!

Regardless of whether it is robbing each other, or active attack or passive counterattack, as long as the survivors of the two sides start a war, there will definitely be casualties.

Therefore, the newly unlocked thickened bulletproof steel plate after the second production level is undoubtedly equivalent to giving a timely rain to the dry land at this time.

Since it is made of thickened bulletproof steel plates, it goes without saying that it is bulletproof and impact-proof. In this way, Chen Fei and the others have a safer guarantee than other survivors in the battle! This is

Based on capital!

Although the newly unlocked spear is far less important than the thickened bulletproof steel plate, it is still something that can be put into use as soon as it is made.

The new additions of He Guantao and Afa, in addition to daily maintenance and modification of vehicles, will definitely join the battle in some crisis situations, so the issue of the distribution of their combat equipment also needs Chen Fei to carefully consider, but obviously this

The duo with simple brains are only very reliable when repairing and modifying cars, but under normal circumstances their brains are always offline. It would be really dangerous to share a weapon like a pistol with them!

So Chen Fei gave the military stab dagger to the two of them and used it as their main weapons. However, considering that everyone in the team had a gun and only the two of them had nothing, Chen Fei also assigned one to each of them.

Type 54 pistol, but for the sake of everyone's safety, bullets were not allocated to them, and hanging the gun on their bodies was just for them to show off.

Chen Fei gave them a total of four military thorns from the airdrop supply box. He Guantao and Zhou Fa imitated Nangong Jin and first put one of the military thorns in the belt around their waists.

In order to look handsome, the two of them asked Chen Fei for a complete set of holsters, belts and leggings, but all they had on them was a pistol and a military spur.

As for the other military thorn, they welded it to one end of the steel bar and transformed the general thorn into a long gun. Both of them had seen the ferocity and madness of zombies, so they naturally felt that keeping a sufficient distance from the zombies was the safest.

, melee combat is absolutely impossible for the two of them!

Chen Fei also feels that long weapons like spears are very suitable for this simple-brained duo. When paired with defensive wooden fences, they can basically deal with the damage without any scruples. It is a completely idiotic and brainless way of fighting, and it is also very efficient.

low risk.

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

The only material required to make a spear is the most basic pig iron block. Of course, this iron is also the main material for thickened bulletproof steel plates, but unlike making spears, in addition to pig iron, four other metals are needed to make thickened bulletproof steel plates.

Although the proportion of raw materials is very small, no matter which one is missing, thickened bulletproof steel plates cannot be made. All of them are indispensable!

Chen Fei originally thought that the only material needed to make thickened bulletproof steel plates was steel, but after asking the intelligent voice system Momo, Chen Fei embarrassingly discovered his ignorance, because to put it bluntly, steel is actually iron, and it is smelted from pig iron.

Come.

To use the very official answer from Momo Na, steel is a general term for iron-carbon alloys with a carbon mass percentage between 0.02% and 2.11%. When a certain amount of chromium is added, it will become stainless steel.

However, Chen Fei also discovered something, that is, in the notes on consumable materials, it was mentioned that metal ore can be used without raw metal raw materials. This means that the manufacturing system directly ignores the smelting process!

According to Mo Mo's introduction, the production of functionally manufactured thickened bulletproof steel plates is a more cutting-edge technology that cannot be achieved by earth's military industry!

Although it is also a bulletproof steel plate, the hardness, impact strength, elongation, and other properties of the steel plates manufactured by the system far exceed the current bulletproof steel plates of the national military specifications.

After understanding these relevant information, Chen Fei could more or less understand the rare metals that needed to be added to make thickened bulletproof steel plates.

But what he sighed in his heart was that as the system became more and more powerful, more and more functions were unlocked, and there were more and more things he needed to do and look for!

Sure enough! If you want to live a life like a salted fish, you can become stronger. Even if you have a system, you can't do it!

But there is nothing he can do about it. In order to become stronger and to survive in the apocalypse, Chen Fei must do it even if he knows that he has to run and break his legs.

After adjusting his complicated emotions, Chen Fei took a look 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 in the inventory has items, and the icon of the defensive wooden fence has the word 33 on it.

For the same item, the upper limit of the capacity of each grid in the inventory is 99. If the number exceeds this, it will be automatically placed in another grid. Chen Fei feels that it is very difficult for him to fill the entire grid in the inventory.

, or it can be said that it is very long. Fortunately, he does not need to think too much about it and just let it take its course.

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

This improvement in material space has exceeded Chen Fei's inherent idea of ​​doubling the space.

The upgraded material space has directly changed from nine square meters of three meters by three meters to thirty square meters of three meters by ten meters, and the height has also been increased to five meters.

Chen Fei felt that this was probably a very user-friendly adjustment made by the system based on the fact that most of the logs in the wood processing plant were seven or eight meters long. This was indeed a happy thing.

After dinner, He Guantao and Zhou Fa began to use the remaining materials to make basic modifications to the maintenance vehicle, mainly welding steel bars on the windows to strengthen the defense, and then used the remaining steel plates to repair some of the severely impacted areas of the doors and compartments.

Reinforcement is done like patching, although it doesn't look pretty.

As for Nangong Jin, Mu Meiqing and Wang Yuanyuan, after the three women inspected together, they returned to the office building to wash up and apply facial masks.

Chen Fei didn't see any apocalyptic feeling from the three women. If other surviving teams saw this, they would definitely complain:

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

"Look at the women in our team. They are all gray-faced and with chapped skin. Look at the women in your team. Are they going to participate in an apocalyptic beauty pageant?"

"Brother! This is the end of the world! Can you be more serious? It's not the end of the world if it's not miserable, and it's the end of the world if it's not hard. We are basically two channels, okay? We are survival in the end of the world and you should go to the Global Travel Channel next door! Damn it!

!”

"..."

In fact, Chen Fei felt that in this tense atmosphere of the end of the world, it was a pleasure to use others' envious, jealous and hateful eyes to please himself...

When the other party got jealous and wanted to take action, they found out... that their damn equipment and combat power were going to be crushed!

At that time, he could say something very arrogant:
Chapter completed!
