Travel through famine years and awaken a post-apocalyptic survival system.

When I got home, it was already quite late.

I started a fire and made a bowl of instant noodles.

After eating, take off your factory uniform and wash it with warm water.

"We still need to get some cotton."

Zhao Qingsong muttered to himself as he washed the clothes.

He only had one thick cotton-padded coat; the other one was thinner and needed to be worn with a sweater and woolen pants.

To be honest, he really didn't want to wear wool pants.

It's too bulky.

After he had finished washing, he quietly returned to the basement and made a large wooden tub out of wood.

Store it in your space and head out.

There were no pedestrians outside at this time.

We arrived at the area with public tap water.

All three faucets were frozen solid.

Having already guessed this outcome, I quietly took out boiling water and poured it over the tap.

After a while, the tap was finally turned on.

……

After working for an hour, I filled the giant bucket with water, put it into my spatial storage, and went back.

Boil water and rinse the clothes.

After cleaning it thoroughly, we got the basement back.

I made a large iron bucket out of a workbench, filled it with red-hot honeycomb briquettes, and added a few more.

Finally, place the clothes on top of the metal bucket.

Use the heat of honeycomb briquettes to dry the clothes.

After finishing his work, Zhao Qingsong lay on the heated kang bed, looking at the large iron bucket on the ground next to him.

With this thing around, the temperature inside the room has risen considerably, but it consumes a lot of coal; the ration is simply not enough to burn.

However, he didn't pay any attention to it and simply lay down on the heated kang and fell asleep.

……

At night, firewood was added to the heated kang (a traditional heated brick bed), and some coal briquettes were also added to the iron bucket.

The next day, just as dawn broke, Zhao Qingsong was awakened by the system's voice.

His eyes lit up when he saw the reward inside.

[Ding, mission complete. The host has survived for another 5 days in a Level 1 shelter. Overall rating: A.]

[Ding! Rewards include: 3 Treasure Chests, 1 Temperature Module System, 1 Toilet Module, and 2 Points.]

[Ding! Host's attributes increased by 1.]

A streak of light flashed by, and Zhao Qingsong felt completely comfortable.

Open the properties again.

[Host: Zhao Qingsong]

[Strength: 12/12, Rating: As weak as a chicken.]

Agility: 13/13, Evaluation: Even a dog can run faster than you.

[Intelligence: 13/13, Assessment: Only slightly better than cerebellar atrophy.]

They quickly began to check the new harvest.

Meanwhile, a new survival mission has been launched.

[Ding! Survival main quest issued: Survive for 10 days. Rewards will be given based on your rating. Description: To help you survive longer, please collect resources as quickly as possible. Upgrade your shelter to unlock more features.]

[Survival time: 0/10]

He ignored the task, but he really liked these two modules.

Temperature module system: can regulate the temperature inside the shelter, providing a more comfortable environment for the host.

Construction materials: (10 iron blocks, 5 copper blocks, 2 plastic blocks)

Bathroom module: After loading, you will get a bathroom with separate wet and dry areas.

Construction materials: (10 iron blocks, 20 stone, 5 copper, 20 glass, 2 plastic)

Depend on!

air conditioner?

bathroom?

Good guy.

These are the good things we're missing!

Quickly put the module to use.

Fortunately, I had collected some plastic from broken basins beforehand, otherwise it really wouldn't have been enough.

With the temperature module system in use, wooden air conditioning vents were exposed in the four corners of the cabin.

They also included a remote control.

"Damn it! What are guns and cannons compared to this thing?!"

I picked up the remote and set it to 30 degrees.

The warm air from the air vents began to spread throughout the room.

One minute

Two minutes.

……

The basement wasn't very cold to begin with, and it warmed up quickly after the air conditioner was turned on.

"Damn, this feels so comfortable! I don't have to sleep on the kang anymore, I can sleep here."

Zhao Qingsong was overjoyed.

Unfortunately, the supplies are still missing glass; we'll have to look for it at the junkyard.

Let's put this aside for now.

Moreover, the water source problem cannot be solved.

They then proceeded to inspect other supplies.

There are still 3 treasure chests this time, and I wonder what I'll get from them.

Without even thinking, I clicked on it.

[Ding: Resources obtained: Level 1 Freshwater Collector *1, Calculator *1.]

【叮：获得物资：大米20斤*1，麵粉20斤*1，矿泉水*10】

[Ding: Resources obtained: Wood*30, Stone*20, Iron Block*10, Gasoline*10L]

Zhao Qingsong looked at the supplies and smiled.

Level 1 Freshwater Collector: Automatically generates 10L of drinking water per day. Note: It can be used independently or integrated into the shelter's water system.

It can be integrated into the shelter's water system, which may be useful later on.

There is no running water in the room.

Once integrated, will there be running water automatically?

With that in mind, I chose to merge.

A flash of white light appeared, and a tap water basin indeed appeared in the corner, with a metal faucet on top.

After turning it on, clear water flowed out of the faucet.

I took the cup and filled it with water.

I put it to my nose and smelled it; there was no strange odor.

It licked it again.

It's just normal water.

This is a good product, very practical, but the quantity is a bit small.

Drinking water is fine, but taking a shower is not.

……

Since it was only 10L, Zhao Qingsong didn't waste it.

To be honest, I'm not very satisfied with the other things, after all, this isn't really the end of the world, and the perspective is different.

A single bite to eat might be more precious than anything else in the apocalypse.

One set of materials can reinforce a shelter.

He doesn't need that here.

Overall, it's pretty good, though, and it's improved his living conditions. He's really happy with the air conditioner; he'll be living in the basement from now on.

Then we'll add some more glass and it'll be all set.

Moreover, this time I used 10 liters of gasoline, which should last for a while.

They focused their attention on the calculator.

Zhao Qingsong fiddled with the calculator in his hand, speechless for a moment.

This is just an ordinary scientific calculator, which would probably only cost a few dozen yuan in later generations, but it wasn't of much use to him!

Sudden.

Zhao Qingsong thought of something.

This thing is of little use to him, but it is extremely useful to the country!

As a science major, I have a good understanding of the development of history.

It's 1962 now.

He remembered that the most advanced computers in China at the time had a processing speed of about 10,000 operations per second, while the scientific computer in his hand had a processing speed of at least several million operations per second.

After the Russians withdrew their experts, scientists used abacus beads to calculate the data for the atomic bomb.

The most advanced 104 computers are in very short supply, and they are used in all walks of life.

According to the declassified archives, even for such an important project as the atomic bomb, computers were only used for 10 hours a week, which shows how rare they were.

This thing was a treasure in those days.

Of course.

He also understood that "speed" is not the same as "ability." No matter how fast this scientific calculator was, it could not replace the bulky computers of this era in terms of capability.

But with these things, many calculations can be reduced in time.

The important thing is that it can be used for research.

We'll find an opportunity to send this thing to the Chinese Academy of Sciences.
