Doomsday disaster: Start by building a shelter

The next afternoon.

Official Shelter No. 9, 055 Security Warehouse.

Under the rigorous operation of the construction robot, the two geothermal generators were successfully operated and smoothly integrated into the shelter's power grid.

At this time, Su Wu had just finished a call with a resident of an official shelter.

From her hand, he got a packaged data file.

Skillfully received and saved.

Su Wu immediately added all 29 songs in it to the player and played them live.

The soft female voice immediately dispelled the silence in the control room. It seemed to bring people back to a green, lively and comfortable summer.

"This song is quite nice."

Su Wu was resonated by the song and felt a little nostalgic in his heart.

Calculating the time, it should be early summer now. In normal years, there will be ice-sweet and delicious watermelons, lush and green leaves, cutting the sunlight into pieces, accompanied by a gentle breeze to help people fall asleep.

Unfortunately, now all this can only become a distant and unrecallable dream.

What is left is only the temperature that has doubled to 60 or 70 degrees.

Under such extreme temperatures, all vegetation will wither.

Add to that the global super fire, drought, and fog that is more than ten kilometers thick in the sky.

The entire world, the surface vegetation that still survives may be less than one percent of the original.

Lost for a while.

Su Wu then noticed that the work of installing the geothermal generator had been completed.

Ye Xi sent him a website address, as well as an account and password through the Internet.

Click it, enter the account and password to log in.

Su Wu found that it was an online mall, which displayed dozens of pages of different tradable goods. And the account has a fund limit of 7 million, which is exactly the same as the income from the sale of the geothermal generator this time.

"It's time to reap the fruits."

Sit up straight.

Su Wu's spirits lifted, and his eyes became serious.

The stage to which his own shelter can accelerate its growth depends on the choice of this step.

After spending a little time browsing the entire mall, Su Wu had a vague plan in mind.

At present, his shelter has been completely built into three floors.

The first floor hydroponic farm realizes the production and supply of rice, vegetables and fruits.

The second floor realizes the needs of daily living, water, small-scale mechanical parts manufacturing and maintenance.

The infrastructure of the third floor breeding factory has been completed. It only needs to invest in chicken, duck and fish cubs, as well as a certain amount of initial feed, so that fresh meat products can be continuously supplied in the future.

From a functional point of view, the most urgent need at present is to officially operate the breeding factory.

"The first batch of purchased materials."

"Five thousand hatchable chicken eggs, two thousand hatchable duck eggs, and two thousand fish fry of different species."

"There are also about five tons of emergency feed."

Compared with the hatched cubs, the price of chicken and duck eggs is lower.

It takes a longer time to cultivate them to the point where they can be released from the cage.

But for Su Wu, he can afford this time.

His shelter warehouse has enough frozen meat products and canned meat. There is no shortage of meat in the short term.

Besides, grass, algae, etc., which are used as alternative feed, also need time to grow.

It matches the progress of breeding from eggs.

The total price of this batch of materials is about 30,000 yuan. Compared with the shopping quota of one million, it is almost negligible. But it solves the biggest problem Su Wu is facing now.

"Then a lot of fertilizer is needed."

Whether it is a hydroponic farm or a feed planting area in a breeding factory, fertilizer is indispensable.

Although Su Wu had a certain reserve before.

But it is related to the foundation and lifeline of the shelter's survival, and it is impossible to achieve self-production in the short term.

No matter how much, it is not too much.

In addition, fertilizer can also be used to make weapons and ammunition. Although it may not be used, whether it is used or not is one thing, and whether it has it or not is another.

Many times, this is the boundary between life and death.

"It won't go bad anyway."

"This opportunity is rare, try to get as much as possible."

Su Wu made up his mind and directly increased the original purchase plan of 50 tons by ten times.

The order for 500 tons of fertilizers was placed, and half of the fertilizer inventory in the mall was emptied on the spot. The price he paid for this was that the balance in his account was reduced by one million.

"Next, we need to add some building materials."

"Mainly cement and steel bars."

Don't look at the materials used by Su Wu to build the shelter. Most of them are almost zero-cost construction waste and stones. Just a thin layer of cement is applied on the outermost. But this can't withstand continuous consumption.

If there is no way to replenish, the two trucks of cement that Su Wu brought last time can only support the expansion of the shelter to the fifth underground floor at most.

That is, about 40 meters from the ground.

Such a distance, compared with the official second-phase shelter project with a depth of 270 meters, is not enough to satisfy Su Wu.

But at this time, Su Wu found that the official shelter did not seem to be as financially strong as he imagined.

Although he wanted to buy, the cement inventory in the mall was only 500 tons.

According to the price of 20 yuan per bag, even if the mall was emptied, only cement worth 200,000 yuan could be bought.

"Not bad."

"It's already ten times more than the last time."

"Don't be too greedy."

After a little disappointment, Su Wu felt relieved. Considering the official ongoing plan to build the second phase of the shelter, he knew that even these 500 tons of cement might be used by the official shelter to support the facade after being scrounged everywhere.

It was already a profit to be able to buy it.

However, there was also good news. The steel bars, another building material that Su Wu needed, were in sufficient stock in the mall.

He placed an order and bought 1,000 tons in one go.

"There are still more than 1.7 million."

Looking at the account balance, there was still a lot left.

There was no point in saving this thing. Maybe one day the shelter's top management would make a policy change and it would be directly reduced to zero.

It would be better to cash it all out as soon as possible.

After a little consideration.

Su Wu set his sights on the sugar that he had been thinking about before.

There are no warnings or purchase restrictions this time, so at least 20 tons must be bought to make up for the regret. Then salt, gasoline and diesel also need 10 tons each. There are also daily necessities such as toilet paper, soap, etc. If the timeline is extended to several decades, the reserve quantity of these things must be at least a thousand boxes.

In addition, various types of drones, high-end and low-end chips, wires, lamps, etc., must be reserved to some extent.

These are the key consumables for the intelligentization of the shelter.

After buying bits and pieces, Su Wu's balance disappeared quickly. In the end, only about 400,000 was left.

"There should be nothing needed."

"The rest can be exchanged for tobacco, alcohol and medicine."

Su Wu doesn't like smoking and drinking. But this does not prevent him from realizing that these things have great appeal to certain specific groups. In many cases, tobacco and alcohol can almost be regarded as universal currency.

The same is true for medicine.

Although it is not addictive, it can be used to save lives and suppress severe pain at critical times. Any human who survives in the end of the world will not deny the value of medicine.

The only thing that is inferior to alcohol and tobacco is that medicines generally have a shelf life. Expired medicines will have a reduced effect or even have a counterproductive effect.
