My Doomsday Shelter Unlimited Upgrades

In modern times, tap water generally comes from rivers, lakes or surface water. After being purified and disinfected by treatment plants, it becomes water that can be used for people's daily life and production.

This method is the fastest way to get water, but now the conditions are limited, and Chen Yang has no way to connect the pipe to the external water purification device.

He doesn't know if the modern water purification system can purify the sewage in the last days, but the upgraded water purification system can definitely.

This idea was also thought of by Chen Yang on a whim, otherwise, if he wanted a large amount of water, he couldn't have opened dozens of wells on the ground, right?

Although the idea is good, the conditions are not so favorable now. We need to open two or three wells to maintain the supply first.

To dig a well, you must have materials.

235 survival points, it looks like a lot, but it’s actually not that many, so you still have to save some.

All the stones were used up in the upgrade of the shelter yesterday, and the wooden door has not yet come to upgrade urgently. Chen Yang plans to spend a morning collecting materials first.

Of course, before that, the newly developed system functions must not be forgotten.

"System, scan your surroundings."

[Scanning and monitoring, no signs of large organisms were found within five kilometers around the host. 】

[Number of scans today: 1/2]

Chen Yang sighed, it's not like there are heartbroken poisonous cows every day.

They also gave away meat, survival points, and rewards. Chen Yang wanted to bring a few more heartbroken poisonous cows. It was better to send two cubs and find a place to raise them.

"That's fine, if it's not a heartbroken poisonous bull, but some kind of chameleon, wouldn't it be too bad?"

Although it was confirmed that there was no danger, Chen Yang still put on the upgraded alloy armor to be prepared.

It's really hot enough to wear this kind of thing in summer, but what matters for life?

In case the ruins on one side suddenly collapsed, the alloy armor might still save his life.

Putting on a bottle of quantum water, Chen Yang came to the female dormitory building yesterday again.

In addition to materials, we will collect some bedding such as mattresses and quilts today.

He has seen a lot of what boys are like. When he was in school, he bought a set of quilts from IKEA. This is considered a very delicate boy. Many other boys just sleep on the bed board, just spread a mat as a bed, and they are still girls. Be more particular about this.

With a lot of experience in excavating ruins, Chen Yang's working speed today is much faster than yesterday.

The items I found today are a bit weirder than yesterday. I think the dormitory yesterday may be a new student, and I haven't had time to arrange many things.

Today's is different, all kinds of broken cosmetics and daily necessities stubble, Xiao Cheng only has two palm-sized camisoles and shorts, and there are boxes and boxes of unopened safety measures, and a lot of textbooks and books , it looks like the dormitory for old students.

Keep it all!

Chen Yang felt that he had become a scavenger in the last days, no matter what it was, it was of value to him.

After digging for a while, finally, the corner of a mattress leaked from the rubble.

Take it apart and see that this mattress is obviously a high-end product, with a thickness of [-] to [-] centimeters. The material seems to be brown velvet, but it has become very worn out now. It has been buried under the ruins for so long, so I don’t know if it is dirty or not. , The big and small openings have also been cut open.

"This is not a problem here! It just works after going back and refurbishing."

After putting away the mattress, Chen Yang conducted a more detailed carpet-like search of the surrounding area, and sure enough, he found the matching bedding and pillows.

The bedding and pillows were as worn out as the mattresses, and the coats were all black, which fit Chen Yang's aesthetics.

If there is a big pink and red quilt, even though no one will look at it in the shelter, he would be ashamed to cover it himself!

With the goal achieved, Chen Yang put more thoughts on the collection of basic materials.

Concrete, steel, stones, wood... Collect as much as you can, race against time, I'm afraid there won't be enough in the afternoon.

Continuing to collect, Chen Yang found another cat nest in the ruins.

It is common sense that cats can be kept in university dormitories, right?

Chen Yang wanted to include the cat litter into the system, but was suddenly blocked by the system.

【Beep!Living things cannot be included in the system, please check the host before re-operating! 】

"Living thing?"

Chen Yang looked deep into the cat's nest, and there was a mass of black objects in it.

"Isn't this a rock?"

Stretching out his hand to touch it, Chen Yang petrified in place.

Where is this stone, furry, and temperature, it's a cat!

It might be due to the backlight just now, he didn't look at the black cat carefully, and mistakenly thought it was a rock.

It has been more than a year since the end of the world. Even if there is a cat in the cat litter, logically speaking, it should have turned to ashes long ago. Why is this cat still warm now?

Lifting the black cat from the cat nest, the cat's whole body was covered with dust and debris, and its breath was also very unstable, showing a dying appearance.

At this moment, the prompt popped up by the system solved Chen Yang's doubts.

[Mutated black cat (unnamed)]:

The mutated black cat that can be used as a pet has been affected by the radiation of the meteorite and has changed its genes. It has survived until now. Using meteorite fragments can upgrade the mutated black cat. After the upgrade, there is a chance to acquire new skills.

Hunting Form: Greatly enhances own speed and strength within 5 minutes, cooldown time is 30 minutes.

System comment: I will give you an alien egg (cat's nest) at the beginning of the game!What hatches depends on luck, and advancement depends on devouring!

"Pet system?!"

Chen Yang felt more and more like playing a game. There was even a pet system, and a black cat could release skills.

He used to be afraid that he would get some kind of autism after living alone for a long time, but now a cat came to accompany him.

"What's the name...?"

Naming is one of his best skills, and the small Chinese dictionary is no joke.

"A black cat, and the ability to be alert to the surrounding environment... Let me call you Black Cat Sheriff!"
