In the apocalypse of natural disasters, she has a universal APP

She hadn't opened the window for a long time.

Previously, the odor caused by the garbage thrown into the stagnant water made her give up the simplest and fastest method of opening windows for ventilation.

Nowadays, indoor air quality is mainly taken care of by air purifiers and green plants. The former removes odors and supplies oxygen, while the latter absorbs carbon dioxide and supplies oxygen.

The machine is powered by an engine, and the green plants...the green plants have space and can be replaced with new ones. Overall, the effect is very good.

Now when she opened the window, the cold night air hit her face. She had a cotton hat on top of her head, a mask on the bottom, and her own glasses in the middle. Even so, the exposed skin was instantly penetrated.

It was almost chilled to the bone.

Recently, I have adapted to the low temperature in my living room, and I can feel the difference once I open the window.

However, it can also be seen that the thermal and sound insulation materials posted throughout the house are indeed good.

She turned on the light, quickly cleaned the small window in the bedroom, and then turned to the balcony.

The balcony windows were large and numerous. After cleaning them, she put a generator and air purifier on the balcony to suck in the odor coming in from outside the windows.

In fact, she didn't smell it. She was wearing a mask. She even pinched a mint-flavored bead in the inner corner, and her breath was filled with a spicy and refreshing aroma.

Of course, she would feel a little regret every time she opened the window and put out the window cleaning tool - when the wind outside blows, the peppermint becomes even cooler, okay?

Three windows in the whole house, the bedroom and the balcony had been cleaned. She thought about it and decided not to leave it behind and went to clean the kitchen window as well.

After the smell disappeared from the balcony and kitchen, she returned to the bedroom. There was a permanent air purifier in the bedroom, but now there is no smell.

However, this time she took out the air purifier to remind her that after the heavy rain began, she chose a new air purifier with dehumidification function in order to cope with the indoor humidity.

But now that the rain has stopped, although the water is still high outside, the electric heater has already started to turn on indoors.

After a few more days of walking, when the temperature drops and the water outside freezes, it will turn from wet to dry.

——You don’t even need to wait until later. In fact, it kind of means that now.

So, she turned off the dehumidification mode of the air purifier and decided to give it a try in the next few days to see if she should keep it on or add a humidifier.

While she was experiencing wet and dry body sensations in the laboratory, the water outside suddenly changed unexpectedly.

One day in early April, after she got up, she went into the space to do morning exercises and wash up as usual. Then she wandered to the window and looked outside. When she saw it, she noticed something strange.

... This water accumulation, why does it feel like it has become shorter?

In fact, there are still sixteen layers exposed above the water, which is still very high. At first glance, there is no big difference.

Just like when the flooding first started, for a thirty-two-story building, it didn't really make any difference whether one or two floors were flooded.

She previously calculated the increase in water accumulation by taking photos of the building opposite, and then comparing the number of floors and height with the previous day.

But now, standing in front of the window, she could immediately tell that something was wrong.

It wasn't because she counted the layers, but the part exposed above the water seemed to have a little... mark? Like a dividing line? Not super obvious, but enough to be noticed.

She quickly counted the floors that were still above the water, and then she was shocked to find that the current location of the water was actually below the twelfth floor.

She was worried that she might count wrongly, so she took another photo. Comparing the two photos together, the reduction in water accumulation was very obvious.

She just...ah? What happened? Why did it suddenly drop? It's even as high as a four-story building, huh?

The last photo was taken on the first day of April. The water was indeed still under the 16th floor, and it had not moved for half a month.

She admitted that because the water level had not moved for a long time, she had been a little lazy about recording the water accumulation, but...it had only been less than a week, so why had it dropped four levels?

In fact, after the rain decreased, the water almost stopped rising. This made her probably expect that the water would recede in the future, but this was not the way to retreat, right?

Is the retreat speed faster than the rise speed when it rained heavily?

It couldn't rise two levels in a week before, so why is it now down four levels?

Where did all the water go?

The water level has dropped. It must be that the accumulated water has other places to go. Now that the weather is so cold and cloudy, not much evaporates, so other water must have been drained away.

But...where does the water come from? What to arrange it with? Where did it go again?

It can't be lost to other places where there is no water, right? She didn't believe it.

This rain—not just rain, but the entire apocalypse, is a disaster happening all over the world.

Although communication was cut off, there was no way to access the Internet, and she didn't know the situation in other parts of the world, but she believed that the impact of this heavy rain should be very wide.

Even if it's not a global torrential rain, it should at least be uniform across the hemisphere.

It’s not just City B or the country where it’s raining. Water is accumulating in several countries. Now that the water level is dropping so fast, where can the water go?

Is the drainage system starting to work? I feel that this is even less likely. When the water started to accumulate due to heavy rain earlier, the drainage system should have been in a state of collapse and abandonment.

Even if the authorities knew about the existence of this heavy rain in advance through golden fingers, in the context of the apocalypse, no matter how much advance repairs were made, they would not be able to withstand the pressure of natural disasters.

To take a step back, even if the drainage system is repaired and ready for use, how is such a fast drainage rate achieved?

This is not like draining a lake. With hard work, the water level can be reduced - this is a global disaster!

The main question is, where does the falling water go?

Everywhere is flooded, which means there is nowhere to drain the water. Maybe the authorities have prepared a place for drainage in advance? Underground or somewhere? You can't launch it into outer space...right?

Ok?

Wei Jiao suddenly felt that she had discovered Hua Dian.

Outer space... is difficult, but isn't there a similar, golden finger space from another dimension?

She opened her mouth, and her head excitedly thought that this might be the truth, and at the same time, a voice kept muttering, "No, no, no, no, it can't really be like this."

As a result, the more I thought about it, the more I felt that this seemed to be a very reasonable explanation!

The accumulated water is collected into the space, which can not only achieve rapid drainage, but also possibly reuse water resources——

Anyway, the officials knew in advance that there would be a heavy rain disaster, and they must have studied the water quality treatment, purification and reuse of rainwater.

Since the evacuation base was built early and officially opened so soon, she believes that the authorities must have corresponding measures in terms of daily drinking water and daily water and electricity consumption.
