The 'primary building materials synthesis module' is about the same size as a microwave oven. Most of the parts are wrapped in metal materials. Some exposed parts reminded Lu Yu of the 3D printer he had seen before.

After loading the ‘high-performance sheet synthesis formula’, one side of the module spreads and extends, turning into a large-capacity funnel, so that the collected material can be put in.

A single synthesis can produce a high-performance plate with a length of no more than one meter and a width of no more than thirty centimeters.

Of course, if you need a smaller size, you can set it through the auxiliary panel.

There are two ways to read the formula, one is a rigorous method.

According to the size of the plate to be made, what should I write directly on 200 grams of iron, 800 grams of carbon, 5000 grams of hydrogen, 50 mg of sodium, αㄳд =@…

A bunch of elemental formulas, not to mention the brain pain, the key is that there is no condition to collect it like this.

The shoddy reading mode of the formula is much milder.

[If you need wood, you can use half a table, two benches, or three...]

【The metal material required can be used for half a microwave or a small oven, or a quarter TV, or an electric fan, or...】

【Fiber materials required can be used as a pillow, or as a fifth of a quilt, or...】

Well, very down-to-earth.

Although something is wrong.

But with this set of formulas, it is really easy to use all the objects you encounter as raw materials.

So in order to synthesize the first board, Lu Yu began to collect it in the pile of supplies at home.

Um...

A wooden door that was replaced because of a shotgun.

Five Coca-Cola cans and two bags of domestic waste.

A piece of replaced window glass, a piece of steel pipe cut when building a shelf.

Half a cup of vodka, a spoonful of salt...

In order to collect the required ingredients, more and more strange raw materials have been added to the raw material funnel of the synthetic module.

The module also made a sound like a donkey gnawing on grass and began to process it with these raw materials.

Even though Lu Yu's shelter was rich in materials, it took him more than 20 minutes to collect the formula materials.

However, it only took more than half a minute to synthesize a board, and a board with a surface shiny look like a blue brick was sprayed directly from the opening on one side of the module.

Before Lu Yu could catch the board, he saw the board fall to the ground and bounced up more than 20 centimeters in a tough manner.

Then it bounced on the ground like a ball for a lot of time before finally landing steadily on the ground.

When he just touched the board, Lu Yu didn't even dare to touch it casually, but only dared to touch it gently with the fingernail of the little finger of his left hand.

After confirming that the plate was not as dangerous as high temperatures, he felt relieved to pick the plate from the ground with a knife.

There is no way, the board is so flat that it is perfectly combined with the floor.

When Lu Yu carefully observed the board, the panel also gave basic information about the board.

【High-performance synthetic sheet (basic type)】

【Fire resistance: Excellent】

【Bulsile resistance: Excellent】

【Structural performance: good】

【Sound insulation performance: good】

【Heat insulation performance: Normal】

[Installation method: Adaptive installation]

[Note: Attach the plate to the building surface and apply a certain force to maintain it for a period of time. The plate can be attached to the building surface by itself]

【Complete a board synthesis and obtain survival points: 5 points】

“Adaptive installation looks amazing.”

Lu Yu raised the board with both hands, a board that was one meter long and thirty centimeters wide, with a thickness of half a finger.

After considering it, the density of this board should be between aluminum alloy board and wooden board.

With Lu Yu's strength, it is not difficult to move.

Lu Yu pasted the board on the newly replaced apartment door, and his encounter with the fake FBA made him realize the fragility of the apartment now.

If he hadn't fired directly like crazy, if the fake FBA agent fired first, then Lu Yu would have gone to hell now.

After the board was pasted on the wooden door, a timer and a force bar appeared on the panel.

Lu Yu directly pressed his body on the plate, and when the force reached the prompt force on the strength bar, he kept it as still as possible.

The countdown began, twenty seconds later, a click sounded in Lu Yu's mind.

The board fits tightly onto the wooden door.

Lu Yu took out his revolver, hesitated and gave up the idea of ​​using bullets to test the plate.

If the movement is too loud, it is easy to cause yourself to be injured by stray bullets.

He raised the fire axe again and slashed heavily at the position where the plate was.

Puff~

There is nothing wrong with high-performance boards, but the impact of this heavy axe makes the wooden door without the board bend due to the stress.

Okay, hurry up and synthesize a few more boards, otherwise this door will be ruined again.

The inventory of the shelter was searched over and over again. Not to mention the wood stored in the past, even home appliances, TVs, refrigerators, and other appliances that were not very useful in the future were used as raw materials.

Lu Yu produced a lot of high-performance synthetic boards that looked like they were, and at the same time they gained a lot of survival points.

However, it is quite a distance between two hundred points.

After the apartment door was wrapped in high-performance synthetic boards, Lu Yu began to paste directly along the entire wall next to the door.

After sticking a wall, he miserably discovered that if many boards continued like this, even one-third of the exterior walls of the apartment would not be pasted.

No, you must be targeted.

Lu Yu first calculated the remaining plate area, and then used the "Eye of the Builder" to observe the structure of the house.

Those walls with thick concrete do not need to be strengthened for the time being, after all, thick reinforced concrete has a certain defense ability.

With limited resources, Lu Yu must concentrate his efforts on major tasks.

For the remaining boards, Lu Yu reinforced several brick partitions separated from his neighbors.

As for the filled brick walls belonging to the exterior wall of the building, Lu Yu had to temporarily give up reinforcement.

Not enough boards.

He gathered the remaining boards and first strengthened the room in the center of the apartment in all aspects.

After all, his main living place in the future will be this small room. Strengthening the defense here will achieve twice the cost-effectiveness with half the effort.

The strengthening of high-performance plates is a passive defense. Under limited conditions, in order to avoid accidents, Lu Yu also needs to enhance the active defense capabilities of the shelter.

Otherwise, if the guy who set fire in the basement was unwilling to take action again, Lu Yu, who was on the top floor of the building, would have become a cage.

The active defense that Lu Yu thought of was not just about preparing more weapons to fight with people.

Instead, we must improve our ability to escape from the apartment when we have no choice.

There is actually no better way to do this, it's just relying on the rope.

Before, from the old man who was rushing to buy military supplies, in addition to military food, he also got a lot of military field equipment.

I don’t know if this guy is trying to make things appear more or why, the rope that he brought to Lu Yu the most was the rope.

The rope with good toughness, heavy load bearing, wear-resistant and combustion-resistant is enough.

It also has all the supporting climbing equipment.

The three windows left by the shelter are located at both ends and the middle of the apartment. Lu Yu fixed two sets of ropes of sufficient length at each of the three windows, and accompanied by climbing equipment to make it easier for him to slip out of the shelter when the situation is not good.

Wait, this is not enough. If you don’t have enough tools and supplies, you will be different?

So Lu Yu packed basic survival materials and tools at three escape points.

High energy density food, durable fire, cold-proof clothing, quantitative medicines, engineer shovels and other basic tools...

The escape rope and survival equipment pack gave Lu Yu a little more peace of mind.
Chapter completed!
