According to legend, thousands of years ago, mysterious and beautiful mermaids really existed in this vast ocean.

These mermaids are in charge of the vast ocean. They have magical powers that can purify the sea water and ensure that the ocean on which humans depend for survival always remains clear and pure.

Whenever fishermen in the ocean encounter strong winds and huge waves or other disasters, mermaids always lend a helping hand without hesitation.

Because of this, mermaids are devoutly worshipped as gods of the sea by fishermen and are endlessly revered and worshipped.

However, as time went on, greedy businessmen learned that mermaids could purify the sea water and became more unscrupulous.

Not only do they discharge all kinds of sewage and garbage into the ocean without restraint, seriously polluting the originally clear blue water, but what's worse, they have the evil idea of ​​making huge profits from mermaids.

Thus, a brutal large-scale arrest operation began.

Merchants hired countless sailors and hunters to search for mermaids. Once they found mermaids, they would capture them with the most cruel means and bring them back to land for human enjoyment.

Some merchants are even so cruel as to cut off the tender flesh of mermaids and sell it to make huge fortunes.

In this way, in just a hundred years, the mermaid population that was once numerous and active in the deep ocean gradually disappeared.

Due to the loss of the mermaids' purifying effect on the ocean, the sea water gradually became turbid.

Every ocean on Earth is no longer what it used to be. They are gradually covered by black, with large numbers of dead marine creatures floating on the surface and emitting a foul stench.

The pungent smell is so nauseating that even the fishermen who used to make a living from the sea can no longer enter the ocean to catch fish and other seafood to make a living.

The ocean, once vibrant, rich and beautiful, has now become a dark and silent abyss.

However, as the oceans became severely polluted, a series of thorny problems began to emerge: global warming, disrupted ocean currents, rising sea levels, and the sea water eroding the land.

It is gradually encroaching on land resources and has a huge negative impact on groundwater resources.

Life on land suffered an unprecedented impact, with bacteria and viruses proliferating and spreading unchecked, triggering massive disease outbreaks.

Water resources became extremely scarce, and vegetation and trees gradually withered and died, leaving the earth in a state of withered yellow and desolate scenery.

Tornadoes, typhoons and other extremely severe weather conditions frequently occur, and natural disasters such as droughts also follow one after another, bringing heavy blows and huge losses to people.

Humanity has entered the era of doomsday escape.

This disaster lasted for a full century before human life finally began to improve. However, the Earth is now scarred and riddled with wounds.

Looking up, the sky was always covered by a thick layer of haze, appearing gloomy and foggy.

Air quality deteriorated dramatically, with suffocating, foul air permeating every corner. Even the violent, raging winds raged through the dilapidated streets and alleys, emitting bursts of piercing whistles.

Faced with such a harsh environment, humans have to be fully armed when going out and wear protective masks with powerful purification functions to resist the invasion of external pollutants.

Seeing this, Jiang Ze slowly closed the thick book in his hand. He silently placed the book on the table, rubbed his eyebrows, and leaned back in his chair tiredly.

At this moment, a man came over and his eyes happened to fall on the book placed on Jiang Ze's desk.

Curious, he reached out and picked up the book, flipping through a few pages. When he saw the events recorded in the book, he couldn't help but laugh and blurted out, "Jiang Ze, this history book must be fake. How could you believe such a ridiculous thing? Mermaids are just a myth."

Jiang Ze sighed helplessly after hearing this. If their research hadn't been so far lacking progress, he wouldn't have thought of looking for answers from the legendary mermaids.

Jiang Ze slowly turned his head, stared at the person standing next to him, and asked, "How is the monitoring of biological change indicators progressing? Are there any new discoveries?"

When Shen Jinghua heard this question, he immediately put away his smile and turned serious. He straightened up and answered solemnly: "It's still the same as before, there are no valuable discoveries."

After listening to Shen Jinghua's report, Jiang Ze was silent for a moment, then turned his head to the window and saw the dark sea.

Jiang Ze frowned tightly, then stood up and said firmly: "Give me the mask, I'll go out and take a look."

Before he finished speaking, Jiang Ze walked towards the deck of the ship without hesitation. His figure quickly disappeared from the room, leaving only a series of hurried footsteps echoing in the silent corridor.

The protagonist, Jiang Zenai, is a highly respected professor of ecology. Shouldering the crucial mission of exploring the source of marine pollution, he resolutely joins the national team aboard the massive ship, embarking on a long and arduous journey.

The ship sailed tirelessly on the rough sea day and night, as if it would never stop.

Jiang Ze and his team members always stick to their posts and never miss any clues that may reveal the truth.

After countless days and nights of searching, one day, they were surprised to find a mysterious island in the deepest part of the ocean.

This island is like a pearl in the ocean, quietly hidden in the boundless ocean.

Soon, they found an amazing plant on the island that could survive tenaciously in such a harsh and heavily polluted environment.

Jiang Ze carefully collected some samples and brought them back to the laboratory for in-depth research. In the following days, they worked day and night at the laboratory bench, conducting a comprehensive and detailed analysis of these precious plants.

After a long period of unremitting efforts, Jiang Ze finally succeeded in cracking the secret of how this vegetation adapts to the polluted environment.

On this basis, they further developed a series of new plant varieties suitable for growing in the current environment.

Afterwards, Jiang led his team to bring the carefully cultivated seeds back to China and plant them widely in various places.

Those new varieties of vegetation are like green messengers, gradually spreading and silently playing the role of purifying the environment until the earth is dressed in green again.
