Three days later, right before Tang Xiaoxiao's eyes, the pitch-black liquid in the glass jar gradually lightened in color, eventually becoming clear and transparent again.

Even though Tang Xiaoxiao was somewhat prepared, she was still unsettled.

That evening, the couple sat on the ground by the lake in the space, with the glass tank in front of them containing four unidentified plants that were growing well. Tang Xiaoxiao wondered if it was just her imagination, but she felt that they had grown a little taller.

After a long silence, Tang Xiaoxiao finally said with some difficulty, "Do you know what this means?"

Han Yunqi nodded; how could he not know?

"Take it to Professor Zhang for a look tomorrow."

The two had already invested a considerable amount of money in a research institute at a university in D City early last year, specifically for research on environmental protection projects, especially water pollution.

This topic was certainly not first proposed by the two of them. China had already invested in research on it a long time ago, but in the previous life, there was no effective progress until the year Tang Xiaoxiao was reborn.

Ultimately, the source of Earth's pollution lies with humanity itself. If everyone refrains from littering, lives a low-carbon and environmentally friendly life, and stops deforestation and the indiscriminate emission of pollutants, the environment will naturally improve.

However, improving the overall quality of the population will take a long time, and the funding required for research projects is a bottomless pit. They both know that this cannot be rushed, but they just want to do something for the Earth they live on.

Unexpectedly, such a huge surprise suddenly came crashing down on us.

If the two guessed correctly, this plant is clearly able to absorb harmful substances in the water, and even use these toxins and harmful substances as nutrients.

In just three days, a closer look reveals that the plants in the glass tank are noticeably thicker and stronger than those growing by the lake.

I just don't know where their absorption limit is, or whether they can really absorb everything.

It absorbs not only harmful substances, but also all the nutrients in the water.

If it's the latter, then this thing really can't be spread easily.

These questions require researchers to determine through experiments.

However, Tang Xiaoxiao thought the latter was unlikely, since these things didn't suddenly appear but had been growing steadily by the lake in the space. If they really had no restrictions and absorbed all kinds of nutrients indiscriminately, the freshwater creatures in the lake would have been ruined long ago.

If an effective method for controlling water pollution could be developed through research using this plant, the sensation it would cause was immense. Just thinking about it made Tang Xiaoxiao and Han Yunqi's blood boil.

Although the spiritual springs in the space have the effect of purifying toxins, their quantity is ultimately limited. Not to mention the entire Earth, the polluted waters within China alone are beyond what Tang Xiaoxiao's limited resources can handle.

But plants are different; they can reproduce indefinitely and may very well restore a pristine environment to the Earth in the future!

Because the idea was so shocking, even though the two of them considered themselves to have seen a lot over the years, they were still stunned for a long time. After calming down completely, they decided to send some samples to the research lab for professional analysis.

It's highly likely that this plant has never existed on Earth, so Tang Xiaoxiao needs to fabricate a plausible explanation for its origin. The only explanation she can come up with is the universal justification of plant mutation.

After all, Tang Xiaoxiao herself made her fortune through farming. So it's not so surprising that she has a strange quirk in this area.
