Day by day in the infinite game

As the streets become more crowded and traffic jams become more severe, more and more exhaust gases are emitted, and the self-purification ability of the natural atmosphere has long been overwhelmed.

Obsidian's task is to provide a large amount of its sticky, tough, and elastic spider silk to Song Yuanze's team. On this basis, they want to study the idea of ​​launching a new low-carbon automobile exhaust "filter".

Its reward is 50 plump and juicy big bugs for each spider web.

Alas, as a rice spider, sometimes I have to bow my head for delicious food.

…

[Congratulations to the players for entering the long-awaited quiz game session! The theme of this round of the game is "Air".

Air is transparent, colorless and odorless in its natural state. It is a mixture, mainly composed of nitrogen and oxygen, and has an important impact on human survival and production.

Air is a necessary condition for the survival of animals and plants. Animal respiration and plant photosynthesis cannot be separated from air.

If there was no air, the planet we live on would be a barren desert without a trace of life.

So, how much do we, who rely on air for survival every moment, know about air?

This round of the game is divided into question and answer mode and survival mode. The question answering is about to begin. Please be prepared, players——]

[1. Name several plants suitable for indoor use to purify the air. (The more correct answers, the higher the score)]

The first thing Tang Qinqin thought of was the succulents she was very familiar with.

"Chlorophytum, pothos, tiger orchid, white palm, succulents."

[2. What is the only naturally radioactive noble gas in nature?]

"Radon (dong sound)."

Radon is a chemical element, ranked 86th in the periodic table of chemical elements. It is odorless, tasteless, and radioactive. Radon is found in all stones and soil, and can also be found in water.

Research shows it is the second leading cause of lung cancer.

[3. What are the main ingredients in car airbags?]

"Nitrogen."

[4. The air wraps around the earth with a thickness of about 1,000 kilometers. This layer of air is called the atmosphere. The atmosphere is divided into five parts. Which layer do humans live in?]

"Troposphere."

The atmosphere is divided into the troposphere, stratosphere, mesosphere, ionosphere and exosphere.

Humans live in the troposphere.

The ozone we often call is distributed in the stratosphere.

[5. The propagation of sound uses air. Is it correct to say that?]

The propagation of sound requires a medium, and all solids, liquids and gases are media for the propagation of sound.

So this statement is correct.

[6. Name the plants that are not suitable for indoors.]

"Tuberose, tulips, poinsettias, plum blossoms, geraniums..."

Thanks to Tang’s father and Tang’s mother, who likes to raise flowers and plants every day, she also knows a little about this kind of health-related knowledge.

[The answer mode is over. Congratulations to player Tang Yuanwai for all the correct answers! The points have been accounted for and the survival mode is about to begin. Players please be prepared! Countdown to 5, 4...]

Before he could check the details of the points gained, Tang Qinqin was brought into the game world.

[Welcome players to the survival mode! In the real world, the increasingly severe air pollution problem has brought various adverse effects to human survival and production activities. And the human beings who caused all this have gradually begun to reap the consequences.

Survival mode simulation environment (1): Automobile City.

Main mission goal: Survive for one week.

Side mission: Break the vicious cycle and awaken the sleeping city.]

As the mechanical sound fell, Tang Qinqin opened his eyes and looked at the surrounding environment.

It is indeed a "car city". As far as you can see, the entire world is almost a sea of ​​all kinds of cars.

Tang Qinqin was standing on the side of a narrow road. There were cars of all sizes parked on both sides of the street, making the main road very crowded.

The sky above his head was gray, with a familiar but more intense and choking exhaust smell. Tang Qinqin quickly took out his mask, put it on, and walked quickly to a nearby building.

She noticed that there were no people in the vehicles parked on the roadside, and the whole street seemed quiet.

Pushing open the heavy door of the building, you will see a room full of bustling people.

How to describe it, it looks a bit like a sardine can, or some morning rush hour subway.

Tang Qinqin, who was startled, gave a friendly smile to everyone who turned around to look at her, trying to hide her inner confusion.

The fearful little hedgehog hidden in her pocket twitched its little nose uneasily and quickly curled up into a ball.

"Hi." It was not a problem to keep "looking at each other" like this. Tang Qinqin raised his hand and said hello to everyone.

The people in the room communicated with each other in low voices for a while, then turned their heads and no longer paid attention to Tang Qinqin.

An old man with a somewhat pale and frail face came over.

"How long do you need?"

His voice sounded a little weak when he heard it.

This meaningless question made Tang Qinqin even more confused, but she suddenly thought about it and said, "Is it okay for one day?"

In a strange environment, girls must learn to protect themselves.

?('ω')?I am really smart.

The old man made a fist with his hand, covered his lips and coughed a few times. His face became paler: "Come in."

Out of a doctor's instinct to save lives and heal the wounded, Tang Qinqin stepped forward to check on the old man's condition.

However, facing the old man's doubtful gaze, Tang Qinqin finally stopped.

It’s better to find out the situation first and figure out how to survive. The rest can come slowly.

Following the old man into the crowd, Tang Qinqin saw clearly that the people were not huddled together in a haphazard manner.

Instead, they were divided into several groups. A group of people sat together. In the middle was a small round table with a pot of green plants on it. The people sitting together looked at you religiously, carefully and orderly.

Breath by breath, I leaned close to the plant and breathed deeply.

That state and expression were like those of a possessed believer, a little nervous.

Tang Qinqin was arranged to sit in an empty seat in the corner.

She looked around calmly for a few times. The people around her, young and old, all had sickly white faces, thin bodies, and coughed from time to time.

She couldn't help but frown.

Listening to the voices and looking at their faces, she confirmed that these people were all suffering from contagious respiratory diseases. Logically speaking, they should be admitted to the hospital for treatment in time. If not, they should rest in bed, be isolated at home, and take medicine for treatment. The most taboo was to gather in groups like this.

.

She quietly stuffed a Chinese medicine pill into her mouth, not forgetting to give half of one to the little hedgehog.

At this time, a girl sitting next to her turned her head and glanced at her.

"It's your turn."

Tang Qinqin was stunned for a second, then he leaned his head forward and took a deep breath as though he was intoxicated.

It was a pot of pothos that was not growing well, and some of the leaves were yellow and wilted.

There is no special smell in the air, except for the sour smell of sweat caused by the dense crowds.

A group of patients with respiratory diseases gathered to "suck" pothos.

Could this be some strange local ritual?

Tang Qinqin was a little confused.
