Armageddon: Shelters Can Be Upgraded Infinitely

After reading this survivor's diary, Lu Yan felt an extremely strong desire to possess something for the first time in his life.

The psionic energy in the ruins of White Bear City is of high value, but those genetic medicines that can improve cell activity are what Lu Yan most urgently wants to get at this time.

"That monster's body festered like that, its head was smashed and it could fight back... This kind of powerful vitality must have something to do with the genetic medicine mentioned in the diary!" Lu Yan thought of the one he killed. That demon ape, its abdomen was almost rotten, exposing the bones on its back, but its vitality was still vigorous...

So, can the genetic disease that Lu Xiaoyu suffered from since childhood be cured by this drug?

The younger sister's illness has always been Lu Yan's heart disease. She has been different from other children since she was a child. Because of physical defects, she cannot go to school or play like normal people. Although Lu Xiaoyu is very sensible, she has never complained to Lu Yan , but many times, he could see the loneliness and inferiority in Lu Xiaoyu's heart.

Yes, it is inferiority complex!

This kind of inferiority complex goes deep into the bone marrow, making Lu Xiaoyu's character extremely sensitive and fragile, and sometimes someone's unintentional words will deeply hurt her self-esteem.

What's more, there are still some **** in this world who like to make fun of other people's flaws...

In order to protect Lu Xiaoyu's fragile heart, Lu Yan has beaten up many guys who intentionally or unintentionally hurt her over the years, from brats to punks, his hands are beyond count!

This kind of personality defect cannot be cured by doing psychological counseling at all. Psychological counseling can only temporarily treat the symptoms, but cannot cure the root cause at all.

Only by eliminating Lu Xiaoyu's genetic disease can her personality flaws be completely cured!

"No matter what, I'm going to try it." Lu Yan clenched his fists.

The harvest of entering the ruins this time was beyond Lu Yan's expectation.

Although he didn't get too many supplies, he got a lot of intelligence information, which also paved the way for the next time he entered the ruins of White Bear City.

…

After finishing packing up the supplies, Lu Yan walked out of the safe house again.

He didn't forget what his main task today was to transform the ventilation and lighting systems of the safe house.

"The lighting system mainly depends on the fire source before it enters the electric power stage. I can make a kerosene lamp or an iron stove..." Lu Yan thought for a while, these two items are elementary tools and can be used in the crafting system It is made at the lowest level of proficiency, and the materials are also very simple.

The kerosene lamp can be used for lighting, and the stove can not only provide a light source, but also have two functions of cooking food and heating.

The lighting system is easy to solve, mainly ventilation and exhaust.

Whether it is a kerosene lamp or a stove, they all need to burn items to provide energy. During the burning process, a large amount of harmful gas will be released. If the ventilation system is not done well, these toxic gases are enough to kill.

Before the power system is fully popularized, the lighting and exhaust system of the safe house need to be designed together.

"The most ideal ventilation system is of course a large ventilation window with front and back penetration, but this design does not meet the actual conditions of the underground safe house, and the safety will be greatly reduced..." A design method emerged in Lu Yan's brain, A ventilation duct similar to a vertical "z"!

This design is usually used for the observation mirror of submarines, which can extend from the underground safe house to the ground. A layer of fine wire mesh is installed at the outer corner of the pipeline close to the ground to prevent small creatures such as poisonous snakes and lizards from drilling in. It can prevent fallen leaves from being blown into the pipeline and causing silt.

As for the inner corner near the safe house, six steel pipes will be installed as anti-theft windows to prevent humans and large beasts from tearing the barbed wire at the outer corner and entering the pipes to forcibly invade the safe house!

There is no need to worry about the two problems of rainwater intrusion and cold air intrusion here. In addition to directing a small ditch on the ground outside the ventilation pipe to connect to the drainage channel, Luyan will also create a sealed glass window that can be opened and closed and installed at the ventilation opening. On the innermost side, once a large cold wave or low temperature weather hits, he will immediately close the doors and windows, turning the safe house into a small nest isolated from the world!

"I need glass, sealant..." Lu Yan carefully calculated the materials needed to improve the ventilation system, other things are easy to say, whether it is steel pipes or barbed wire, the survival system can be manufactured.

Only glass and sealant, Lu Yan has no crafting materials now!

But fortunately, these two items are not rare items, and the price in the trading field is very low. Lu Yan still has about 8 liters of drinking water in his hand, which is the hard currency in the trading field!

In the trading field at this time, there is nothing that two bottles of mineral water cannot buy, if there is, then add another bottle!

[5 square meters of ordinary single-layer glass]

[Price: 100ml drinking water or 300g meat]

…

[5 square meters explosion-proof glass]

[Price: 300ml drinking water]

…

【Black sunshade glass】

【price…】

Lu Yan opened the trading field and searched briefly. About 70 or 80 pieces of glass trading information appeared in front of him, and ordinary glass with low strength and thin thickness was naturally not among the choices. Lu Yan directly fixed his eyes on an explosion-proof glass. on the glass.

This kind of glass has strong bearing capacity, sound insulation and warmth retention. Even if it is violently hit, it will not explode. The adhesive inside it will tightly bond the fragments together, and there will be no flying fragments. wounding incident.

Although its price is a bit expensive, it is not painful at all for Lu Yan.

And more importantly, Lu Yan used high-quality materials to build the safe house. Although the price paid at that time was relatively high, the comfort and safety of the safe house would be greatly increased, and the daily evaluation of the next day would also be based on The excellence of these construction materials gives Luyan a corresponding high score award.

It's a virtuous circle.

So now Lu Yan is not afraid of high commodity prices at all, as long as he can improve the performance of the safe house construction, he will spare no expense!

Soon, he spent 300ml of drinking water to buy 5 square meters of explosion-proof glass, and exchanged 100ml of water for two cans of 500g sealant.

After the purchase, Lu Yan did not quit the trading field immediately, but started the daily leak-picking link. In the early days of the doomsday, many players would have to sell some precious resources at low prices because of survival needs. This is the best way to pick up leaks. opportunity.

"Hiss... This player whose ID is Liu Yuanyuan, why has so many products on the shelves? And the price is very wrong!"

A few minutes later, Lu Yan frowned.

In the process of picking up leaks just now, he discovered a strange phenomenon. A female player named Liu Yuanyuan listed at least 80 kinds of goods on the trading field, from food to drinking water, snacks, from tools to building materials, and even two A black iron treasure chest!

There are so many types that it is dazzling!

In just 40 or 50 hours of entering the wilderness, this female player's luck is so good?

And what Lu Yan couldn't understand the most was that the prices of the goods Liu Yuanyuan hung on the trading floor were very wrong, they were ridiculously high!

A pack of potato chips costs 5 liters of drinking water!

A rice cake, the price is one hundred tons of gold ore!

A screwdriver, the price is 500 catties of beef!

This kind of price far exceeds hundreds or thousands of times the value of the product itself, but anyone who has no brains will never buy it!

"If she was a game NPC who came out to regulate the market, then she shouldn't come up with such an outrageous price..." Lu Yan was puzzled, the other party's behavior seemed to be a deliberate attempt to not sell the product.

I don't want to sell it, and hang it on the trading field...

The only explanation is...she's showing off.

Show off your wealth!

"On the third day of the doomsday, I have never died before showing off my wealth in such a high-profile way!" Lu Yan sighed with emotion.

At this time, the world channel was also boiling over the sudden appearance of this rich female player.

"Fuck? Who is this Liu Yuanyuan? How can she have so many resources?"

"I was so jealous that I bit the roots of my teeth! I worked hard for three days and only got 300ml of drinking water and 2 pieces of toast. Compared with others, I am a waste!"

"She's so lucky!"

"Rich woman, please take care of me!"

"After seeing these transaction information, I found that there were two people standing in my safe house, one was me, and the other was also me, because I was split..."

In the world chat channel, players fully expressed their envy and hatred towards Liu Yuanyuan. Of course, a small number of players also reminded Liu Yuanyuan out of good intentions, telling Liu Yuanyuan not to be so high-profile in the early days of the doomsday, which may cause fire.

"Miss, let's keep a low profile. There are everyone in the wilderness now. If you are targeted by bad guys, it will be over!"

But what people didn't expect was that Liu Yuanyuan, who had been very silent on the world channel, came out to speak at this time.

[Liu Yuanyuan: I don't want to do this either, but my luck is so good that I can get so many resources at will... What do you want me to do? 】

[Liu Yuanyuan: I also want to keep a low profile, UU Reading www.uukanshu.com but my strength does not allow it! 】

[Liu Yuanyuan: Tsk tsk, I'm eating potato chips and fruit now, thinking you can't even drink water, it's really...unexpectedly cool! Hahaha】

Liu Yuanyuan's three sentences immediately detonated the world channel.

Her face of being a villain made all those people, be it good intentions or malicious, instantly target her.

"Heavenly madness will bring rain, and human madness will bring disaster!"

"Are you showing off Nima?"

"Stinky Sanba...I curse you to die within three days!"

Amidst the insults, Liu Yuanyuan's attitude was still very arrogant.

[Liu Yuanyuan uploaded pictures]

[Liu Yuanyuan: Go on, you sour dogs, my sister, I am sitting here eating watermelon and singing, watching you bark! 】

In the picture uploaded by Liu Yuanyuan, she is holding half a piece of watermelon in one hand and Copic potato chips in the other, with a relaxed posture!

The players in the world channel were mad with anger, and directly greeted Liu Yuanyuan's family all over the place.

Witnessing this scene, Lu Yan pondered for a moment, and typed in a very serious dialog box:

"@柳元元, young people, don't think that temporary good luck can last forever!"

"When you gain an advantage, don't waste your time on meaningless things like showing off and showing off your wealth. You should spend your time on learning knowledge, enriching yourself, and expanding your survival advantage!"

"Good luck will only favor you for a while, but knowledge will accompany you for a lifetime! Only continuous learning can improve your survival time in the wilderness!"

"Well, let me test your knowledge about geography..."

"Where's your home?"?
