A few days later, in Miao Er's reluctant and weeping eyes, Lin Han comforted her again and again, only to be let go by the little girl, and finally boarded the plane, and returned to Yunzhou after three trips.

Not far from the airport is a long river that was once crystal clear, but now it is heavily polluted, and the green water stinks.

Passing by the bridge, Lin Han couldn't help frowning and stopped to look at the river in front of him.

He remembered what a teacher had said: Every country that grows stronger, agriculture and the environment have made great sacrifices, and this process is a history that will inevitably repeat itself.

In the past, Britain had the "London Smog Incident" that shocked the world because of industrial pollution, and a smog directly killed thousands of old, weak, sick and disabled, so that mankind suddenly woke up from the beautiful vision of industrialization.

In order to catch up with these developed countries on the road to industrialization, which have already spoiled the environment, other relatively backward countries have to continue to spoil the environment and quench their thirst.

As a result, the environmental problem has become a worldwide problem, almost unsolvable.

Like the river in front of you, it can be said that it is very common in the whole of China and even the world.

"Gaia, how do you feel about the current environment?"

"I don't know...... It's never been this bad, so I don't know exactly how bad it is...... It felt like I was sick and I was a little scared. Gaia looked very depressed.

"Before that, will you do anything yourself?" Lin Han asked.

"Just as you can't interfere with your heartbeat and blood flow, it's hard for me to interfere with specific environmental issues. Gaia said slowly, "What I can do, in your opinion, is more like a rule, nothing special, and it won't attract too much attention from you......"

Lin Han listened and was silent for a while.

"Before I met you, for so many years, I could only watch quietly and do nothing about the things that frightened me...... Now I can at least do something with you, so, anyway - Lin Han, thank you......" Her voice was a little warm.

"That's what I'm saying, what's polite to me, or let's raise my salary. Lin Han touched his nose.

Gaia: "......"

Obviously, she is a principled Earth.

"You try the intermediate creature permission, this permission, you can do a lot of things. ”

"I almost forgot if you didn't say it. Only then did Lin Han remember the middle-level biological authority that could manipulate microorganisms.

With such a windy authority, try it quickly.

Intermediate Biological Clearance - Can manipulate and influence all microorganisms within a radius of one kilometer.

The so-called microorganisms are all tiny organisms that cannot be observed by the human eye, mainly including bacteria, viruses, fungi, and some tiny protists.

There are far more microorganisms than other organisms. For example, the number of microorganisms in the cultivated layer of soil in one acre of land can exceed 100 billion, and the weight adds up to at least the weight of an adult.

Huge amounts of microbes are everywhere, and their power can be blind or very powerful.

In Lin Han's perception, the surroundings were up and down, in all directions, whether it was the smelly river water in front of him or the seemingly clean ground, they were actually densely covered with various microorganisms, and it was almost impossible to find a blank space.

With a thought in his mind, within a radius of one kilometer, a large area of microorganisms with the ability to decompose matter quickly gathered and floated towards the river in front of him.

Microorganisms gathered and in the blink of an eye, they covered a large area of foul water.

Under Lin Han's thoughts, the microorganisms entered a state of excitement and began to frantically decompose various pollutants in the water body.

Although it was not deliberately selected, under the siege of a large number of microorganisms with decomposition ability, this area of water suddenly seemed to boil, a large number of bubbles bubbled, and various gases escaped and dispersed.

"Whew-"

The mist evaporated and became cloudy, which immediately attracted the attention of a large number of pedestrians.

"What's wrong with the river?" people quickly ran over to watch, and there was a lot of discussion.

"It seems that the environment is getting worse and worse, and the river is burning on its own!" some people sighed.

"Shoot it down!"

"Shocked! The man was silent, the woman was ......"

"I want to send it to ......"

People gathered more and more, gathered around Lin Han, looked at the vision in the river and were amazed, discussing and taking pictures.

Little did they know, however, that it was a young man beside them who had created the vision.

Microorganisms with the ability to decompose come from afar, some die, some quickly reproduce offspring, and the endless stream continues.

Gradually, as various pollutants in the water continue to decompose, the mist evaporates, and the large area of water in front of me becomes clearer and clearer.

"Huh, what's going on?"

"The water is getting cleaner?" some people wondered.

"I'm afraid that the extremes of things will be reversed......"

People are talking even harder.

More than ten minutes passed, and when Lin Han stopped manipulating these microorganisms, a piece of water that extended hundreds of meters forward with the bridge as a line was clear, as if it had restored the scene of many years ago, which shocked a group of onlookers.

However, Lin Han immediately realized that although he had stopped manipulating, there were still a large number of microorganisms in a state of excitement, constantly decomposing various pollutants in the water.

Although the speed is slowing down, the clean waters are slowly expanding.

"What's going on?"

"You've just stopped manipulating, but the effect is still there, and it's much less efficient, but it's going to last at least a week. "It's about — five minutes for two whole days." Well, it's good to manipulate microbes, right?"

It's not just powerful, it's just against the sky!

Lin Han was amazed, and then asked, "But there is a question, why can't I affect the microorganisms inside the human body at all?"

Within a radius of one kilometer, all microorganisms in the air and water can be directly affected or manipulated by him. But he is completely powerless and even ignorant of the microbes inside the human body.

"Not just humans, you can't influence the microbes in any living organism. If you can manipulate the microorganisms inside the organism, isn't it equivalent to directly affecting the higher organisms, and of course the intermediate creature authority can't do this. Gaia said.

Lin Han nodded: "Can the high-level creature authority affect humans?"

"Any level of biological clearance will have very little effect on humans, and at most it will slightly weaken the hostility that others will have towards you. Gaia said, "However, when you get full creature access and meet a few other conditions, you can get life permissions. With the right to live, you can influence people's physical condition, and of course, people's thinking and consciousness still cannot be directly affected. ”

Life Permissions......

Hearing this, Lin Han couldn't help but think about it.

......
