My Doomsday Shelter Unlimited Upgrades

Owner: Chen Yang

Completeness: 100%

Space: 10m10m4m

Facilities: wooden bed, wooden bench, well water extractor, poor soil...

Upgrade Direction 150: Reinforce the structure and strengthen the ability to resist disasters, [-] survival points are required.

Upgrade Direction 70: To expand the floor area or storey height, [-] survival points are required.

Upgrade direction three: change the material of the shelter, greatly enhance the durability and other attributes, and require 2000 survival points.

System comment: The wooden coffin becomes a sarcophagus, a great improvement in life!

"It will take 2000 survival points to upgrade the material again. This is not a small project."

Although it looks like a lot, Chen Yang is still full of energy, and he has not forgotten the survival point algorithm of compound interest.

Today's quality of life is improved, and the survival points given every day will increase in the future. 2000 survival points may be saved in half a month.

Looking further down, Chen Yang was dumbfounded by the system's poisonous tongue, but it also reminded him of some things.

He hasn't solved the ventilation and lighting system yet. There is only a stone house with thickened wooden doors, which is not unreasonable to say that it looks like a sarcophagus.

The door and the house are upgraded separately, and now there are no extra stones, so the problem of upgrading the door has to be solved until tomorrow.

The first thing to solve is the lighting problem. After replacing wood with stone, the whole room is more opaque.

After thinking about it, Chen Yang set up a three-step basic policy to solve the lighting problem.

The first step, fire source lighting.

With the system's scanning capabilities, he can make sure that there are no dangers around the shelter, so that he can set up torches around the shelter for illumination at night.

The second step, reflected lighting.

Using mirrors to reflect moonlight is also a way of lighting. Generally, it is used more in underground shelters, but it can also be used on the ground.

The third step, the age of electric lights!

As the name suggests, it is to return to the age of electrical appliances. This step is still a bit far away from him, but it will be realized sooner or later. As a modern person, how can he bear to use a torch for a lifetime?

The first and second steps are what he can do now, one for outdoor lighting and the other for indoor lighting.

To let the moonlight into the house and reflected on the mirror, you have to open a window first.

The synthesis function of the system is basically omnipotent, including the manufacturing formula of glass.

【Sand】3+【Soda Ash】1+【Limestone】2=【0.5㎡Glass】.

He had collected so much sand and concrete just for this moment.

Limestone can be obtained by decomposing concrete again, and soda ash is actually soda, but he doesn't have it now, so he can only use survival points instead.

1 survival point corresponds to 1 unit of soda, suitable!

Several glass windows of different sizes were made in succession, and Chen Yang placed the windows on the walls of the stone house one by one according to the plan.

Just like placing the shelter at the time, the installation of the windows is no need to do it yourself, just choose the location.

While arranging the glass windows, Chen Yang also upgraded the windows twice.

I’ve seen it all here, are you sure you don’t want to bookmark it? QAQ

Chapter 11 Designing Ventilation and Lighting Systems

The first upgrade is to make the glass windows into one-way glass, so that the outside can be seen from the inside of the house, but the inside of the house cannot be seen from the outside to prevent people from prying.

The second upgrade is to strengthen the firmness of the glass window, turning it into tempered glass, so that it will not break with a light touch.

Of course, the glass windows can continue to be upgraded to very good glass, and the survival points required will also increase a lot, Chen Yang can't afford it for the time being.

He didn't make the windows too big because of the firmness. The tempered glass is definitely not as strong as the outer wall of the stone house. If it is too big, it will be easy for intruders to take advantage of it.

If conditions permit in the future, he will definitely get a super-large glass window to come out, just like the mansion he has seen before traveling. He will build several floors first, and the bedroom will be designed on the top floor. The outer wall will only use a super-large French window. You can enjoy the scenery through the curtains, how beautiful is that?

Not only that, there must be a lot of space outside the floor-to-ceiling windows, set up a sun umbrella, sunbathe during the day, jump into the private swimming pool, eat some barbecue and drink some red wine on it at night, and it is best to have a tender model for you He puts on sunscreen...

As for the charging process after applying sunscreen, Chen Yang also thought of a lot, anyway, it's the end of the world, so what's wrong with it after thinking about it.

In fact, except for the young model, he can realize other aspects of the layout. It's okay to think about these things, and it can be regarded as beneficial to the design concept of the shelter layout in the future.

Bringing back the thoughts, the glass windows have been installed and upgraded, and the next step is to make mirrors.

The synthesis method of the mirror is similar to that of glass, except that there are some materials that Chen Yang doesn't know, and the only thing he knows is aluminum.

Things made of aluminum are more shiny, which is one of the raw materials of mirrors, and it is relatively common in daily life. He also collected some aluminum materials during today’s expedition, but the amount is not much. used up.

The size of the mirror is 1m0.5m. Chen Yang made a total of four mirrors and placed them in the four corners of the stone house one by one. When night falls, the reflection of the moonlight from the four mirrors will brighten the interior of the stone house.

As for the ventilation problem, Chen Yang designed two simple vents. The vents are made of iron blocks, and the appearance looks like a Chinese character.

【Simple Vent】:

Upgrade Direction 5: Change the structure of the vents, slightly increase the ventilation efficiency, and need [-] survival points.

Upgrade Direction 15: Increase the exhaust fan, greatly increase the ventilation efficiency, and need [-] survival points.

System review: It is recommended to directly use the air conditioner!

Chen Yang shook his head helplessly, life without electricity is really difficult.

The upgrade direction [-] is obviously in place in one step, but can the exhaust fan still be turned manually?You have to use electricity too!Without electricity, it means that there is one less upgrade direction.

The current situation can only be done with once again.

"Upgrade direction one, upgrade."

After the two vents have been upgraded, the shape and structure are obviously more precise and scientific, and the size is no bigger than a palm. After thinking about it, Chen Yang installed them beside the two walls.

This time he didn't quite agree with the system's comments.

The air exchange effect of the air conditioner is indeed better, but this is not the only thing he considers.

After Blue Star's appearance was changed, smog, sandstorms and other natural disasters also increased suddenly. If the air quality deteriorated, he had to create another air filtration system.

To be on the safe side, it is best to have a complete internal circulation system to ensure the quality of breathing air.
