The dark room where these arms are stored turns out to be a large safe made of metal.

Unfortunately, the lock head has been smashed into a big hole by Lu Yu's bricks.

‘Function-rich brick’ is so scary...

Lu Yu originally wanted to dismantle the entire safe home directly and continue to use it as an arsenal.

But the arsenal directly welded the building structure, and the only dismantling tool in his hand was the "functional brick", which would be destructive once it was dismantled.

The heavy safe finally turned into a pile of scrap iron and would soon be thrown into the 'primary building materials synthesis module' as raw material to synthesize high-performance sheets.

After the arms were moved home, Lu Yu temporarily locked them in the room where he lived with an iron cabinet.

The rich family's luxurious decoration and collections directly filled Lu Yu's shelter.

The matter of picking up trash has to be temporarily stopped.

It is time to consume supplies and transform the shelter.

The once expensive pieces of furniture, all kinds of shiny and colorful appliances, and all kinds of the most fashionable appliances...

No matter how valuable it was in the past, it was ruthlessly thrown into the mouth of the huge funnel at this time.

The ‘primary building materials synthesis module’ is running.

The sound of dada dada dada~ kept coming.

As high-performance synthetic boards were spit out, groups of text floated on Lu Yu's panel.

【Survival Point 5】

【Survival Point 5】

【Survival Point 5】

【...】

Lu Yu only retained the gains of the rich family, or something that could be used or that might be useful for the munitions, fine wine, warm fur products, and rolls of wires.

This time, the number of high-performance boards produced by rich raw materials is more than half the number of last time.

This also allowed Lu Yu to begin to improve the transformation that was not completed last time.

Some exterior walls of the apartment are filled with brick materials. Perhaps in some films and television, such walls can block the attack of guns and bullets.

But in fact, except for a few pistols with very little power, most rifles and machine guns have bullets that are enough to smash such brick walls.

Considering the disturbance of being a fake agent, Lu Yu focused on strengthening the defense towards the inside of the building and the defense of his own living room.

Now that the New York Public Library is controlled by a group of gangsters, and the explicit flag of the "King of New York" is hung, Lu Yu has to consider the possible threats of these guys at any time.

Nowadays, the materials are sufficient. Lu Yu pasted a layer of high-performance synthetic sheets on the exterior wall of the apartment, whether it is the reinforced concrete part or the brick wall.

In this way, the walls of the entire apartment have basic bulletproof capabilities. According to the instruction manual of high-performance boards, even heavy machine guns are now difficult to penetrate the walls of the apartment.

Even low-level explosives such as grenades and grenades may not necessarily do anything to the exterior walls of the apartment. At least heavy weapons must be used to damage the apartment walls.

The remaining plates are not enough to completely strengthen the internal partition walls, and Lu Yu made some modifications to the partition walls in the shelter in a targeted manner.

The main purpose is to adjust the design concept, which is originally based on residential functions, to be mainly based on safety.

In fact, it is by modifying the location of the door opening and re-opening the partition wall, several spaced back-shaped channels are formed in the apartment.

Each passage is connected to the central room where Lu Yu lives, but if the external defense fails and an enemy really attacks the apartment, then Lu Yu can also use the return channel to deal with the enemy.

However, the remaining high-performance plates are not enough to strengthen all partition walls, so Lu Yu can only strengthen some important parts first.

In the central room, Lu Yu formed a dark room compartment by adding a partition wall made of high-performance plates.

The precious arms and ten-day survival backup supplies were placed in it to guard against possible threats.

Before becoming a reincarnationist, Lu Yu was a rookie architectural designer, although he had some design experience.

But now he is laying out a refuge of doomsday after all, and all his changes depend on films, TV series, books, online materials and threats he has experienced and observed in the past.

After making these major changes, Lu Yu made some minor adjustments.

For example, in the original window position facing outward, several holes that can be opened and closed were taken out again.

The functions of these holes can enhance his vision of the outside world on the one hand, and on the other hand, it is used as a shooting hole. Once facing the attack from the outside world, he can use his pretty good firepower and mellow shooting skills to counterattack.

He believes that design skills can be described as mellow.

This lawyer was once considered a lawyer who grew up touching a gun, but his shooting skills were only proficient.

After Lu Yu achieved his achievements and his body was strengthened by "Technique 1", he felt that he was not only more agile when doing construction work, but also was easy to play with guns.

Otherwise, he wouldn't have been so brave enough to beat the fake agent to the point of pissing.

In addition to guns, reconnaissance and vigilance is also essential.

Outside the building, Lu Yu can detect the situation by observing windows and shooting holes frequently.

And the interior of the building is not that convenient.

Municipal power supply has long been paralyzed. Although he prepared generators and gasoline in advance, he did not have suitable monitoring equipment at all.

Of course, the copy world we are in now is not as popular as in the previous life for various wireless transmission and small surveillance equipment.

He can only choose the local method now.

Through the existing thin fishing line, pull to the entrances of the passages in the apartment building, and then arrange them into small warning traps.

Once someone is caught, he will touch Lu Yu in the shelter through the fishing line, reminding him to be prepared for alert.

But such a small trap is too primitive, and the practical distance is limited, so he probably can be used on this floor of his apartment.

Although the lighting in the apartment building due to the power outage is poor, if you meet someone who is careful and even experienced, it is still easy to find these small traps.

Lu Yu had thought of learning some ways in war movies, where the grenades and other explosives in the arsenal were made into thunder.

But after thinking about it carefully, Lu Yu himself is not a careful person. Maybe he will forget the thunder and blow him up.

Besides, he hasn't searched the apartment building carefully. If there are survivors, Lu Yu has no grudges and grudges with others. If he accidentally touches the thunder, wouldn't it be a vain to add psychological burden to Lu Yu?

Forget it, Lu Yu set up the fishing line trap and returned to the apartment.

Today's apartments add a bit of solemnity to the shelter.

A line of text came from the system panel:

[Congratulations on achieving the achievement: Eat the earth-class armed fortress]
