My Doomsday Shelter Unlimited Upgrades

In today's situation, time is more important than money.

The issue of water resources is still the first to be solved.

Chen Yang remembered some survival documentaries he had watched, in which there were mainly two ways to obtain drinkable fresh water.

One is the method of digging wells.

Second, the distillation method.

The first method, as the name suggests, is to dig underground well water on the ground. This method is used more in the wild. Chen Yang plans to try the second method first, and dig a well if it fails.

Taking the axe, Chen Yang collected 15 units of wood, 10 units of stones, 5 units of plant fiber, and 5 units of steel around the shelter.

The steel material is naturally obtained from steel bars, and the system's decomposition of external materials is not unlimited. For him who only has a basic shelter, he must break it into a relatively small piece to decompose.

You know, steel is a superior metal material than iron. There are countless steel bars in the collapsed ruins, but he can only pick up those small pieces. Apart from being greedy, he really doesn't know what words to use to describe the fluctuations in his heart.

As for the other things in the ruins, Chen Yang has not found anything particularly valuable yet.

Perhaps the ruins are too thick, and the real treasures are buried under it. According to his current ability, he is not enough to dig through the layers to find out.

However, he found a thing that can increase the joy of the mood:

Collector's Edition Photo

This building used to be a dormitory for boys. I don't know which boy posted a photo in the dormitory before. When the building fell down, he picked it up, and now it belongs to him.

I have to say that this boy's taste is not too different from his, and the post is Hashimoto Yulai, Shen Kuyongmei and other teachers who are more popular nowadays.

Chen Yang swallowed, and put the photo into the system. Looking at this thing is too thirsty, and when there is water, take it out and enjoy it.

Chapter 3 The drinking water crisis is resolved!

Back at the shelter, Chen Yang took another sip of water and collected some hay around the shelter.

The first thing to do in distillation is to light a fire.

Pound part of 1 unit of wood into sawdust, part of it into firewood, build a bird's nest-shaped space with hay, and then fill it with sawdust. This is a simple fire source.

Chen Yang folded his trouser pocket and took out a lighter.

There are many mosquitoes in summer, this lighter was originally bought for some mosquito coils, but I didn't expect to use it here.

"Heaven will not kill me!"

Chen Yang secretly rejoiced that maybe this was also a kind of fate. If he hadn't bought this lighter the day before the time travel, it would still be a big problem to light it now.

The dry grass is on the verge, and starts to burn along with the sawdust.

Chen Yang marked out a small area and controlled it so that the fire source did not burn hotter. He was afraid that some terrible creatures would be attracted.

The problem of the fire source is solved, and the next step is to manufacture the distillation vessel.

Distillation is a word in chemistry. Usually, beakers are used for distillation, but now the conditions are poor, and he is still reluctant to use steel, so he can only use wooden cups first.

Make the wooden block into the shape of a small strip, and then tie it back and forth with 1 unit of plant fiber, and a cup is finished.

He purposely made the mouth of the wooden cup a little smaller. The cup looks like a "convex" character from the side. This design is for the convenience of waiting for distillation.

Chen Yang followed the same pattern and made an identical cup. The mouths of the two cups were connected, and they were placed flat. One cup was filled with colorful waste water, while the other was empty to collect distilled water.

Put the side of the waste water on the fire, and dip the cup on the other side into the cooler waste water to cool down, and a simple distillation device is ready.

Chen Yang wiped his sweat, feeling a little uneasy.

It was his first time doing this kind of thing, and he didn't know if it would be successful.

After a while, Chen Yang heard the sound of 'gurgling' coming from the other side of the waste water cup, presumably the waste water inside had boiled and started to evaporate.

At the same time, the system popped up a prompt:

【Simple distiller】:

Wastewater can be initially distilled to extract pure water.

Distilled water capacity: 5/600ml

Upgrade Direction 30: Speed ​​up distillation, increase capacity, slightly increase extraction purity, [-] survival points are required.

Upgrade Direction 60: Change the structure and material of the distiller, greatly increase the distillation speed and extraction purity, and require [-] survival points.

System comment: It is said that it can extract pure water, but no one really dares to drink it?

It can be done!

Chen Yang was a little surprised. The crude equipment he built casually can be upgraded!

He originally thought that he had to produce a finished product before he could upgrade, but when he looked back at the coffin-like shelter, it was not difficult to understand the system's judgment.

Pure water from a simple still?

Dogs don't drink it!

"System, upgrade direction [-], immediately upgrade..."

The words came to an abrupt end, and Chen Yang quickly stopped his instructions, his excitement almost surpassing his rational thinking.

Now he has 100 survival points, if he upgrades the alembic, there will be 40 left, and he can't use it rashly.

Chen Yang put the existing materials in the backpack in turn to try the upgrade options. Except for steel, other materials have no effect on the upgrade of the still.

Even if all 5 units of steel are used up, there are only 20 survival points left at most.

Chen Yang pondered for a while, and decided to try the well digging method again.

It doesn't matter if you can't dig out water, as long as you can upgrade, you must have water to drink.

Well water is not only cleaner than the 'pure' water distilled from waste water, but also produces more water, which is definitely much more efficient than distilled water.

Just do it!

【Record】: Wood-5, Plant fiber-2

[Record]: Successfully made a wooden shovel (common)

After getting the wooden shovel, Chen Yang found a place to dig not far to the west of the shelter.

The sun rises in the east, and the wellhead is set in the west so that it can hide in the shadow of the shelter and minimize the evaporation caused by direct sunlight.
