"Young man, do you know why there is a haze layer? Why does the haze layer surround our entire planet? Why does it never disperse all year round, and even replace land and sea, becoming the new surface of the earth?"

After giving the reward, Fang Buping introduced the patriarch and elder of the Purgatory clan to Buchou, and sent her to communicate with these people and took over the task.

Then he turned around and said to Wei Bubing very seriously.

"It should be because of... air pollution, and extremely tiny dust particles floated into the air with the disturbance of the airflow..." Wei Bubing replied hesitantly.

Although this is the world of the game, it is still very scientific in some context settings.

So Wei Bubing will hesitate because this is obviously not the exact answer. If the truth is like this, there will be too many things that go against common sense that cannot be answered.

Sure enough, Fang Buping was slightly disappointed when he heard this: "That's it? That's all your understanding of the haze layer?"

"Tip you. Since you have chosen to take planting as your major, you will definitely have some understanding of the evolution of organisms. I ask you, in the first 2 billion years of life on Earth, what kind of organism was that endured the harshness of the original environment of the earth, slowly decomposed and solidified the atmosphere of high concentrations of carbon and sulfur oxides, and finally transformed the current atmospheric environment suitable for our breathing and survival?"

This is the difficulty of learning business skills. The skill tutor will ask you some subject-related questions from time to time, which is equivalent to a random exam.

If you answer correctly, you will increase your favorability and add your skills. If you answer wrong, you will deduct your favorability and punish your skills. It is not the right major in reality. You often have to hang up your skills every day, and you will not be deducted in this way.

Fortunately, Wei Bubing has a brain control chip. He can retrieve information at any time, but these problems cannot be defeated.

However, even if there is no brain control chip, this question is common sense, and it is easy to answer: "It's plankton."

"That's right, it's plankton." Fang Buping clapped his hands fiercely.

Looking at the old man's bright eyes, Wei Bubing suddenly understood what he meant, and was incredible: "You mean. Is this haze layer composed of plankton?"

What is plankton? You can see through your name. Floating, swimming, and living organisms are a mixture of algae, bacteria, jellyfish, krill and other organisms that live in water.

Can those who fly in the sky still be called plankton?

It seemed as if Wei Bubing's doubts were seen. Of course, the fact is definitely that. The director's line was designed like this, and Fang Buping said: "Why can't it be a plankton?"

"With the catastrophe, the radiation intensified and the environment deteriorated sharply, many creatures have undergone mutated, with the widest distribution, the largest number, and the longest-lived plankton on the earth has also undergone mutated. Is this strange?"

"Of course, mutation may be natural. It may also be artificially induced, in short..." The old man spread his hands.

"But, what, how could it be?" Wei Bubing couldn't hide his doubts.

Most of the things like plankton live in water, and of course there are very few, such as bacteria attached to suspended objects, which can float in the air.

But after all, their density is greater than that of air. Even if they are blown into the sky by the wind for a while, as time goes by and as the wind weakens, they will eventually settle down.

Although it may be extremely long, or even as long as several years, in the end...

It is impossible to keep hovering like before you, all the time.

Moreover, as mentioned earlier, the air density in the haze area is hundreds of times that of the normal air density and is one-something that of the water density.

According to the simplest laws of physics, they should also be settled onto the ground and then replaced with fresher air?

"It's very simple, because they have evolved the ability to fly."

The ability to fly? Plankton can also evolve its ability to fly? Don't joke?

Biological activities have evolved for many billions of years from ancient times to the present. Although their pure flight capabilities have evolved independently from dragonflies to bats to birds, all of them rely on aerodynamic principles...

With the body-shaped movement ability of plankton, it is impossible to evolve stable flight ability with this;

Even the haze layer built with this flying ability should never be like this unless... they have other ways to obtain buoyancy.

Looking at the expectant gaze of old man Fang Buping, Wei Bubing was blessed to his heart: "Can they obtain energy to resist gravity with the help of the earth's magnetic field?"

The earth's magnetic field is undoubtedly one of them, which can cover the world, day and night, and has few relatively stable energy sources.

This also explains the reason why electronic signals in the haze layer cannot penetrate. If the haze layer is entirely composed of plankton suspended by the power of the earth's magnetic field, the electromagnetic signal will obviously not be able to penetrate.

During the process, the energy will be swallowed up by plankton that feeds on it.

Or some people may wonder that according to the direction of the earth's magnetic poles, the power to levitate the creatures should not be generated, and the direction is not right at all.

This is not aware of the setting of the wasteland world.

According to Wei Bubing’s few understandings about the world setting, the catastrophe has the greatest impact on the earth, which is to increase the energy of the earth’s core rapidly and accelerate the rotation speed of the earth’s core.

While this aggravates the crust activity on the earth's surface, it also causes abnormal disorders in the originally stable earth's magnetic field.

The Earth's magnetic poles have long since been no longer the original direction, but have been divided into several complex and changeable magnetic poles, with a very fast rotation speed. They seem to have various movements of swallowing, fusion or disintegration before.

In short, the Earth's magnetic field that was previously gentle and stable and could indicate the direction was no longer there.

Instead, it is a violent new magnetic field that rotates rapidly and changes unpredictably.

The changing magnetic field produces an electric field, which is an important reason why the weather on the earth's surface changes three times a day after the catastrophe.

At the same time, this also provides a theoretical basis for plankton to obtain energy through the Earth's magnetic field and levitate in the air.

"You answered correctly!" The old man slapped Wei Bubing on the shoulder hard, deeply impressing the spirituality of this student.

At the same time, a series of prompts from the system sounded. Your favorability with Fang Buping increased xx points, your planting skills increased xx points, and your xxxxxxxx...

This is OK? Wei Bubian's mouth twitched.

Fang Buping said to himself: "Plantoplankton has evolved a suspension system dominated by magnetic forces. You also know that in addition to magnetic monopoles, magnets have two poles, which are naturally attracted to each other..."

"Magnetic plankton reproduces rapidly, and its population is getting bigger and bigger; the larger the population, the stronger the magnetic field formed by polymerization, and the more conducive it is to their survival and reproduction..."

"After the survival of the fittest by the environment, the fittest survives, and finally forms a stable biome layer at a distance of 300 meters to 3,000 meters on the surface..."

"That is, the extremely dense and unreasonable haze layer."

"In places where it is too low, the charged particle flow and cosmic rays cannot penetrate, making it difficult to obtain energy replenishment; in places where it is too high, it is too thin, and plankton cannot survive..."

"This layer of haze separates the electronic signals from the world below to the sea of ​​clouds, but at the same time it also stabilizes the chaotic earth's magnetic field. It still maintains a relatively stable magnetic field on the surface of the earth. It is used to block the blowing of the solar wind..."

"At the same time, plankton will also swallow up the polluted dust, volcanic ash, waste gas from human industry and other suspended objects carried in this high air."

"When they are alive, only by relying on these things can they form the magnetic levitator in their bodies; when they die, they will lose their ability to levitate and settle to the ground."

"In this way, they constantly purify the atmosphere of the earth..."

"It's like billions of years ago when the Earth was still in its rebirth, they participated in the evolutionary process and changed the entire face of the Earth..."

"It's strange why I'm talking so much to you, right? I'm going to talk about the key points soon."

"My lifelong ideal is to plant the food that humans need anywhere possible. No one in this world will starve to death."

"You might say that since haze is entirely made up of plankton, isn't the problem solved?"

Plankton is an important source of food in this era.

Many plankton are directly edible; even if they are not edible, they will become edible after processing by certain means.

Not to mention among plankton, there are also krill, which has the highest protein content, which is both nutritious and delicious.

If the haze layer is really composed of plankton, would it be a pile of grain covering the earth?

"But unfortunately, plankton in the haze needs to absorb suspended objects to form their suspension device, which is rich in various heavy metal particles, and cannot be processed and eaten, unless a lot of energy is wasted..."

"But in that case the efficiency will be low, it's better to plant other crops honestly..."

"But everything has exceptions. Plankton is the real bottom of the biological chain, even if they can fly. All kinds of creatures living in the haze layer, including animals and plants, rely on them to provide food."

"Most organisms have evolved the ability to adapt to this harsh food source, and utilize the enriched heavy metal ions in their bodies, producing special abilities such as light, electricity, and magnetism."

"But I believe that there must be some creatures that have evolved their purification capabilities. They can absorb various toxic substances from plankton and excrete them through their own ways, leaving behind clean and usable parts."

"No matter how this ability is achieved, no matter whether such a creature can be eaten directly, as long as one can be found, even if it is toxic, it will be a huge improvement in cultivating crops that can be planted in the haze layer!"

"In recent times, I have detected unusual disturbances of heavy metal ions from this steam volcano's eruption species."

"I believe that around this active volcano, there are most likely crops I want to look for. Young man, are you willing to help me?"

Of course I am willing! Wei Bubing must have agreed.

But before I could speak, I had already visited the entire cave... I didn't realize it was actually a volcanic cave, with smog filling the cave.

The brother and sister walked along the cavity of the bubbles, and unknowingly they had already penetrated into the cave without knowing it.

"Brother, you are developed! We are developed!" After not worrying about turning the cave, I finished talking to every NPC that I could talk to, and came to my brother happily, "Hey, brother, have you not finished talking yet?"

"Yes, I just heard that old man say no, no, no..." A few people along the way were quite interested in the novel journey between the brother and sister, watching the other side, and they felt very much like Wuwu saying this.

Wei Bubing clicked on the confirmation option: "Is it still quite interesting? Don't you think it?"

Don’t worry about not seeing it. Without the right to speak, the onlookers just sneered: “What’s interesting about it?”

As soon as he finished speaking, Master Fang Buping laughed: "It's very good! Very good! When people get old, they like to nag. You can listen to my old guy's nagging from beginning to end, not anxious or impatient, not angry or angry, and a child can teach you!"

"Dangdangdang" is accompanied by the sound of a series of copper coins falling into pockets.

Your favorability with Fang Buping has increased xx points. Your planting skills have improved xx points. Your xxxx has increased xx...

Several teams watched the party and covered their faces and left without such a slap in the face!

"Hey, don't leave, don't leave, this matter has something to do with everyone." Wuhou hurriedly reached out to greet them?

Only then did everyone remember that they were so excited that they shouted happily that they would be developed.

What has become more developed? Even if there is anything good, their current role is not in the same place at all?

Stop with doubt. After hearing the words of Buwuwu, I was stunned.

"Nani? This, this, this is actually a new copy!"
