Chapter 8 Designing Ventilation and Lighting
“Let’s first think about how to modify the ventilation system of the base. This is a big problem in the underground shelter.”
Sitting on a wooden chair that is a little bit uncomfortable, Soma began to recall the knowledge of civilized times.
And the shelter design in major doomsday movies
Underground shelters require a large air filtration and conditioning system, but any ventilation ducts opened outside will become a safety hazard.
Therefore, in Sumo's idea, it is best to use an internal circulation system, but the prerequisite is water and electricity, so that oxygen can be produced by electrolysis, which provides the possibility for internal air circulation in the entire facility.
Of course, it cannot be completely sealed from the outside world. The stability of this completely sealed environment is extremely poor, and ventilation holes to the outside world are still necessary.
In order to be concealed, this vent cannot be too large, and there must be a sealable switch that can be closed at any time.
If there are no terrain restrictions, it is the best solution to set the vent under the rocks that are exposed only at low water levels in the river bed, or on an uninhabited island.
These slender ducts can pump purified and filtered fresh air into the bunker, and can be closed at a critical moment to use internal circulation.
But given the current conditions and equipment in the shelter, this idea can only be a conception.
After looking around at the items currently on sale in the trading channel, Sumo decided to stick to the most mechanical design.
Utilize the periscope structure of the submarine.
A window with dual functions of ventilation and lighting is opened in the center of the shelter.
The specific design is to dig out a cavity directly above the shelter and install glass with better light transmittance.
And punch holes in the glass for ventilation to ensure that air can flow through the pipes.
Going down the dug cavity, a "Z" shaped turning hole can be made in the middle of the hole.
In the "Z" shaped hole, two plane mirrors are installed parallel to each other and at a 45-degree angle to the incident light. Through two reflections, the incident light is transmitted into the shelter to solve the lighting problem during the day.
After the first layer of ventilation glass, a mechanical explosion-proof glass can be designed to ensure that the explosion-proof glass can be closed in a disaster to prevent liquid or toxic air from flowing in.
Even a high school student can come up with such a simple design, but it would be troublesome to implement it.
Without matching tools, it would be a big project to penetrate all the way to a shelter five meters underground while ensuring accuracy.
But
“I have a system!”
With his current understanding of the system, Sumo has completely understood how the system is played.
When there are no materials, the system wants to use survival points to create materials out of thin air, which is very costly.
But once you have the materials, the system functions more like a construction team, and you only need to spend a small amount of survival points to achieve the purpose of upgrading.
After thinking about it and confirming the feasibility, Sumo opened the trading channel.
Currently, the resources he can use are as follows:
Ordinary mineral water (1000ml), Nether Energy water (600ml), and 10 pounds of big Lieba bread.
As for the remaining pet eggs and energy bicycle blueprints, he has no intention of trading them.
Trading channel.
[Seller: Sumo]
[Trade items: 50ml Nether Energy Water]
[Required items: Explosion-proof glass]
[Remarks message : Water that can strengthen the body, don’t miss it if you pass by, only two units of glass are accepted, private message with good quality]
[Seller: Somo]
[Trading items: 15ml mineral water (maximum 975ml)]
[Required items: 1 iron block (can be exchanged 1/1 times per person)]< br>
[Remarks: Each person can only complete one transaction]
After the two items were successfully put on the shelves, Sumo spent another 25ml of water to buy two units of mirrors with good reflective properties, and replaced ordinary mineral water with Use them all.
Somo exchanged 15ml of water for 1 iron block. Although it was an extremely black-hearted businessman's behavior, for some players who were struggling on the line of life and death, it was no less than a savior's behavior.
In addition, Sumo also had his own plan for limiting each person to one transaction.
Water is now regarded as liquid gold. What he wants is to be consumed, rather than being acquired and hoarded by some thoughtful people.
World Chat Channel.
"For those of you who are short of water and have iron blocks, go to the trading channel and take a look. Su Shen is selling water again! One person can only trade once, hurry up!"
"Damn it, Su Shen is so awesome!"
"Haha, it's already too late. Fortunately, I followed Su Shen's personal channel in advance and grabbed a sip of water. I didn't even notice that Su Shen is now in his forties. Fans, can you passersby grab it?”
“Where did Sumo get the water? Yesterday he spent 700ml to buy the illustrated book, and today he bought 1000ml of iron. Is that too much for you?” Come and see, Su Shengui's psionic water can actually strengthen the body and cure diseases. As long as the explosion-proof glass is used, who would hurry up and change it! , I dug all morning and couldn’t find a drop of water, I’m so thirsty”
"."
There is only one speech per day, and a large group of people gather to discuss it on the world channel, not to mention the grand occasion on the regional channel.
Even Sumo’s personal private messages at this time were flooded.
First of all, in less than two seconds, the transaction of the iron blocks purchased for sale was completed, and 65 units of iron blocks were quietly lying in the inventory.
There are countless people here holding other resources and shouting for a sip of water.
"Water is so popular!"
Suma thought to himself.
In the past two days, others have been trading resources to buy water, but he is the only one who is exchanging water for resources, so he naturally looks unique.
Using the filtering function in private messages, Sumo used keyword iron blocks to filter out 80% of useless private messages.
After using the search, I picked out dozens of private messages with explosion-proof glass and started to check them.
After scrolling through many private messages about wanting to buy more water using ordinary-quality explosion-proof glass, Sumo finally found an eye-catching one.
Feng Mengyue: "Su Shen, I have a piece of ordinary quality explosion-proof glass, but I think you will not like it. If you are willing to increase the price, I can trade you a piece of fine quality and a rare piece. High-quality explosion-proof glass"
The avatar is a woman with a delicate face and a heroic face.
Seeing the exquisiteness and rarity, Sumo frowned and smiled.
The current quality classification currently has five levels: ordinary, excellent, sophisticated, perfect, and rare.
Feng Mengyue, a member of the female class, was able to obtain rare-quality explosion-proof glass on the second day of the game. This is obviously her luck.
“He raises the price as soon as he opens his mouth, but he doesn’t take the initiative to quote. He seems to be a difficult person to deal with.”
Su Mo shook his head, not being fooled, and responded to Yijun.
Su Mo: "You should understand the current value of psionic water. There are so many things on the market, but I am the only one that can improve your physical fitness. As for the explosion-proof glass, I bought it for a shelter. It doesn’t matter whether the window is good or bad.”
Feng Mengyue: “Is 300ml okay?”
Su Mo: "Don't even think about it. It's just two pieces of glass. It's not worth so much. If you don't want it, I will drink it in the afternoon."
Feng Mengyue: "I'll think about it"
Seeing the other party's reaction, Su Mo burst out laughing.
He is the only one selling psionic water in the market. It is an absolute seller's market. Once he decides not to sell, the buyer can only stare blankly.
Two minutes later, news about Feng Mengyue came again.
Feng Mengyue; "I am adding information to the two pieces of glass, 300ml of psionic water"
Sumo: "What information?"
Feng Mengyue: "About how I obtained it Information about these glasses”
Looking at the chat box, Sumo thought for a while and then agreed.
In the apocalypse, materials are valuable, but information is priceless.
It's like killing a chameleon. If he doesn't have enough information, he may only be able to deliver food while wearing all the equipment.
After hanging up the private transaction channel and uploading the designated seller of 300ml Nether Energy Water, the transaction is completed.
[Record]: You have lost 300ml of psionic water.
[Record]: Congratulations on getting explosion-proof glass (fine)*1, congratulations on getting explosion-proof glass (rare)*1.
[Record]: Whether to extract glass information
"Extraction"
After the words fell, a voice played in the empty shelter.
“Ruins will spawn in the wilderness from time to time. When I got up today, a mysterious ruins spawned next to me. It looked dangerous inside, so I only found a few pieces of glass on the outside. When I wanted to continue exploring, the ruins suddenly disappeared.”
Has anyone seen it? It feels like it’s a stand-alone game. I’m crying...(woo woo woo woo)
