Movie King Dad, your daughter came to you from the countryside.

Ground vegetation can be cut down and eliminated.

What about algae in the sea?

You know, marine algae provide [-] to [-] percent of the oxygen in the atmosphere every year.

The proportion of plants on earth is too low.

Based on conclusions drawn by climatologists and environmental and botanical scientists.

If no effective method is found, the oxygen content in Blue Star's atmosphere will exceed the threshold in 20 years.

It is difficult for humans to adapt to such an environment, and there is a high probability that they will be wiped out.

This will be a common disaster for all mankind around the world.

If we want to change the status quo and curb the continued reproduction of marine algae, it is a top priority.

Otherwise, even if humans are lucky enough to survive, they are doomed to live in dire straits.

By then, some animals and plants will continue to grow wildly and even get larger.

During the Carboniferous period 6000 million years ago, Blue Star had extremely high oxygen content, and animals and plants at that time were generally giant in size.

Nie Fuyao and others had already thought of this.

At this time, experts from around the world are being united to thoroughly improve the sources of pollution.

The research and development process does not happen overnight.

It was not all smooth sailing during this period, and there were constant conflicts due to different positions.

After a long time, Nie Fuyao suddenly felt bored.

"If you think it's fun to argue, then I'll quit."

After the meeting, she dropped this sentence and left.

Everyone present was stunned.

They also shut up.

Nie Fuyao couldn't quit.

The technological skills she mastered were far beyond the comparison of those present.

Once she withdraws, they will definitely lose this race against time.

For the sake of the fate of mankind, they had to shake hands and make peace.

Even if only temporarily.

The next study was much more harmonious.

Nie Fuyao led the world's top scientists to continuously visit and collect samples for in-depth research.

Time passed slowly in a state of urgency and silence.

Disaster occurred on the 30th of the year.

Everyone gathered in front of a huge pool.

There is sea water in the pool, and there is a giant seaweed inside.

This seaweed is by no means a benign creature. It has sharp saw teeth that can easily cut people.

Nie Fuyao poured a cup of special liquid into it.

After the initial calm, the water in this pool, which was comparable to a football field, rolled violently under the crazy dance of the seaweed.

Everyone quickly took a few steps back.

The seaweed didn’t change much during the first week.

A month later, technicians scanned the size of the seaweed and found that it had not continued to grow.

Three months later, after another scan, they found that the seaweed had shrunk by nearly ten centimeters.

At the same time, Nie Fuyao took samples, and after testing, he found that the pollution source content in the seaweed had also begun to subside.

At this rate, it would take about half a year to completely eliminate the pollutants, but it would take nearly three years for the body to degrade until it returns to its original ecological size.

"Three years!" Someone was worried.

After all, they don't have much time left.

Nowadays, more and more people are suffering from oxygen poisoning, and the number continues to increase every year.

After three years of observation and stabilization, it will be released into the ocean. It will also take a long time to spread.

With seven years left, can it really be done?

This is almost the critical moment that determines fate.

But they did try their best.

The research on removing pollutants is not too difficult. With Nie Fuyao at their side, it only took them two years to successfully develop it.

Everyone's scientific and technological research level has also been greatly improved.

The rest of the time is spent studying how to restore these algae plants to their original size.

if not?
Killing is absolutely not allowed.Once a large number of people are killed, the oxygen in the air will be greatly reduced, and death will still be the way to go.

But if they are not killed in large quantities, the reproduction speed of these giant algae plants is no joke.

In particular, the global ocean currents are interconnected. If drugs are put into the ocean, they will only continue to spread.

Or kill them all.

Or all survive.

There is no other way.

Nie Fuyao said: "No need to worry, we will make it in time."

About two years and seven months later, an observer ran in excitedly.

"It was successful. The algae completely stopped growing. There was no change for fifty days in a row."

This is great news.

According to previous observations, daily scan data shows that the algae are constantly shrinking, without exception.

After the sudden stop of shrinking, everyone was surprised and worried that this small seaweed would continue to shrink.

However, for fifty days, there was no sign of further shrinkage, which was great news.

Nie Fuyao, however, calmly said: "Continue to observe for half a year."

The observer responded and left.

Three years have passed.

The algae completely stopped growing.

The pool that once had only one giant seaweed was now densely covered with proliferating seaweed, which was very beautiful.

Everyone cried excitedly when they saw such a petite and cute seaweed.

Some people knelt and lay on the edge, praising the little seaweed like crazy.

It's not too small to say small, about seven or eight meters.

Even so, they thought it was so cute that it could be up to [-] meters long at first.

At first, the body size shrunk relatively slowly. Later, according to observations, the longest daily shrinkage was [-] or [-] centimeters, and sometimes it was as little as [-] or [-] centimeters. It seemed to depend on my mood?

Although the seaweed does grow very big, it shouldn't at this moment.

after new year.

Nie Fuyao sprinkled the liquid into tens of thousands of ocean mapping points around the world.

After that it’s just time.

The land was left to the pilots for high-altitude spraying.

For the rest of the year, scientists around the world are closely watching concentrations of pollution sources in the oceans and on land, as well as changes in flora and fauna.

New data is released almost every once in a while.

Everything is going in a good direction.

Many years later.

Blue Star has finally returned to its former glory.

Nie Fuyao also entrusted Mo Linyuan to help collect some animals and plants from various worlds and send them to Blue Star.

After decades of existence, the Guards were eventually disbanded.

Several members of the Wushuang team are also elderly.

They have made a lot of money over the years, enough to eat and drink well for the rest of their lives.

"Captain, people nowadays cherish the environment. How long will they remember it?"

Nie Wushuang curled her lips, "Two generations at most, no more."

Several people were silent.

They are tempted to refute.

But the facts cannot be refuted.

After all, cases like this have happened more than once or twice.

"If you can't remember it, you can't remember it."

Nie Wushuang said: "In times of crisis, there will always be people who will step forward to save the world. If they cannot be saved, it will be nothing more than destruction together."

"Death in one's own hands is not an injustice, and there is nothing to regret."

"It's just cause and effect. I won't give you a chance to change again and again."

"Look away."

This time her sister is here, next time...

What does it have to do with her. (End of chapter)
