Surprise Hotel

When the two million boxes burst, Xianuo stood in front of the warehouse with a gloomy expression on his hips, watching the cans pouring out like water.The canned food appeared inexplicably, but she knew that it must be Lu Xing's ghost who had become a system of nutrition.

When Lu Xing rushed over, he looked at the cans and scratched his head, "The warehouse is a bit small, let's build another..."

The construction of the new warehouse takes time, but in the end, Midler appeared and transferred all the cans to the gold tower.

"Now that there is no free trade among the residents in the city-state, the pyramid should be used as a backup warehouse." Midler generously offered the pyramid.

Two million boxes of cans are piled up on the bottom layer.Except for the aisles, everything was full.

However, if these cans are distributed according to the population, it is not even enough for the current city-state residents to eat.The current solution is to use capsules to replace food.

Lu Xing began to feel that this was not the way.

The pressure brought by the population really made him suffer.

So he released another message to admit the refugees in batches, and the acceptance time for the next batch was postponed to one month later.From now on, 10,000 people will be admitted every month.

The population is temporarily controlled at about 3 million, and food is distributed free of charge, but it is not acceptable.

Lu Xing then released the currency.

The main form of currency is a metal plate with a special watermark.The face value ranges from one yuan, five yuan, ten yuan, twenty yuan, fifty yuan to one hundred yuan.

Men have to rely on hunting and quarrying to carry goods or participate in scientific research to earn the corresponding currency. Women cannot sit back and enjoy the benefits. Women have to work in light industry factories or educational institutions, or serve as shop assistants.

Commodity supermarkets are set up in the streets of the city-states, and the daily food and drinking water needs to be purchased with currency.

Children’s education is free. Lu Xing believes that this is the key to cultivating younger generations and a welfare system is necessary.

Because the biggest businessman is the city-state, the gap between the rich and the poor among the residents of the city only depends on whether they are diligent and the importance of the work they are involved in.

However, new problems also emerged. For example, some people would rob and sell themselves for money. These bad behaviors were all included in the code and prohibited.

Without setting up prisons in the city-states, keeping prisoners is a waste of resources.Accumulated penalties based on crimes, and after accumulating to a certain level, they are directly deported.

In this way, a lot of stability in the city-state.

Those who get something for nothing can't survive by eating and drinking, and the entire city-state operates efficiently.

Lu Xing once again took precautions to the system tasks, relying on the issuance of currency, setting up supermarkets and other tasks, and obtained new task rewards.

Acquire intermediate mineral knowledge.

Get an opportunity to exchange items.

Obtain crop seeds.

As soon as he mentioned crop seeds, Lu Xing remembered that he had also placed a researcher in the agricultural base!

For a while, thinking about how to make the city settle down, I forgot about it!

He hurriedly went to check the results, and Xia Nuo, old Jason and Yuan Ling were relaxing at this time, and they wanted to take a look with the past.Lu Xing did not stop him, and took them along.

To be honest, Lu Xing is not hopeful about the result. Perhaps there are more sophisticated methods in this era, but as a physics student, he is very clear that the long process of nuclear radiation recovery has to wait for the half-life of nuclear radiation elements to end. The half-life of radioactive substances can be as long as tens of millions of years.For example, the half-life of uranium is forty-five thousand years. This means that if there is a kilogram of uranium, half a kilogram of uranium will still exist after 45,000 years, and a quarter of a kilogram of uranium will still exist after 45,000 years. In another four to five thousand years, one-eighth of uranium will still exist.

This is a terrible phenomenon.

The current nuclear radiation content has been attenuated for thousands of years, coupled with the evolution of humans, has had minimal impact on humans, but plants still cannot be grown on it.

When I rushed to the agricultural base, the result was a bit unexpected.

What caught your eye was a green.

green!plant!

There was a look of surprise in everyone's eyes.

Lu Xing stepped forward to check and found that the green colors had emerged from the huge pool next to the test field.

Hydroponics!

Yes indeed!Why didn't I think of this way!

Seeing a group of people approaching, the ragged man got up from the pool and put down the test tube in his hand.

"Grand Duke, I have cultivated green plants as scheduled."

"Good job!" Lu Xing walked over and patted the man's shoulder with a smile.

"I don't think this is a good way." Old Jason frowned. "The principle of hydroponics is very simple. It only needs pure water and nutrient solution. But nowadays, there are few pure water without radiation. Even our drinking water can hardly reach the level of zero radiation, which is why the life span of modern people is generally low. He uses such a large pool of pure water to grow plants, which is simply a waste! If this method is feasible The last Duke must have implemented hydroponics technology a long time ago. In the final analysis, it is probably because of the lack of fresh water resources that people are not even drinking enough to grow plants!"

Old Jason's words made Lu Xing startled, and he frowned again.

"Grand Duke listened to me to explain that this is not pure water I use." The ragged man explained, "These are all underground wastewater."

"Waste water?" Lu Xing's group also showed surprised expressions.

"Let's take a look at these green plants." The man guided a few people closer.

"Green algae?" Lu Xing recognized the plant species at a glance. This was not a crop, but aquatic green algae.

"This thing is called Nostalgia crescenta. The main component of nuclear waste is strontium, and this algae has a very strong reproductive ability, and it can even grow in nuclear-irradiated water sources. Its subcellular structure is rich in sulfates. Adding barium to it, because the solubility of barium and strontium in sulfate is relatively low, barium and strontium can be deposited to form crystals. By controlling the barium and changing the sulfate concentration, the degree of deposition can reach more than 90%. As the man explained, he took out the precipitated crystals from the water and showed them to him, "Instead of waiting for the radiation to decay, it is better to actively filter them."

"You guy... It turns out that you are not an agriculturist, but a water purifier!" Lu Xing finally discovered his true identity.

"The original technology for water purification was all from the underground city. Some of the few camps dug a few water purification experts from the underground city to solve the water purification problem. Most of the remaining camps rely on purchasing pure water from the underground city. All the refugees who can't drink pure water can only drink the polluted water for a short time..." Old Jason said, his eyes sharpened, "Could it be that your Excellency is from the underground city?"
