Shen Li's cry attracted the attention of the others.
Qin Lin walked over.
"Boss Shen, what's wrong?" professor Liu immediately asked.
"look at the willow leaves in this bucket." Shen Li immediately pointed at the bucket and said.
"Yi!" professor liu looked at the bucket and was also surprised.
Qin Lin also noticed the abnormality.
Yellow spots started to appear on the special willow leaf duckweed in the bucket.
This yellow color was like the yellow of autumn leaves.
Moreover, as time passed, these yellow spots increased in number, just like the spots on a human face. Once they reached an age, they would grow uncontrollably.
when some of the yellow dots connected together, they formed an even larger yellow spot.
Shen Li frowned,"is it going to wither?" After all, there's no way for plants to survive in this level of pollution."
Professor Liu shook his head and said,"under normal circumstances, it shouldn't have withered so quickly even in this kind of sewage .." &Nbsp;
Qin Lin also frowned slightly.
He had just taken this special willow leaf floating duckweed out of the game, so he could only understand its condition from the remarks. He couldn't figure out the situation.
"The same thing happened to the Willow leaves in this bucket." shen li suddenly pointed to another bucket and said.
Qin Lin and professor Liu looked over and saw that the Willow leaves inside had indeed turned yellow.
not only that, but the other buckets of willow leaves also showed the same situation. yellow spots began to appear on them.
As time passed, large areas of yellow spots also appeared on the Willow leaves in the buckets.
A few hours later, the special duckweed in the first bucket had turned yellow and was in a completely withered state.
"The rate of withering is too fast." Professor Liu frowned. this is not normal. Is there something special in the waste water? "
"It shouldn't be possible." shen li shook his head. " you city's wastewater testing is extremely strict. there are experts and nature reserves watching over it. they check the nearby rivers at all times. the factory wouldn't want to die. "
Just as they were discussing, they revealed looks of surprise.
Because on that completely withered yellow willow leaf floating duckweed, black dots actually began to appear again, and more and more.
It was as if the yellow dot had repeated itself.
very quickly, the willow leaf duckweed in the other buckets also withered and turned yellow. then, black spots also began to appear.
The Willow leaf floating duckweed seemed to change color.
Looking at the unusual scene, Shen Li and professor Liu no longer thought that the yellow color from before was the withered yellow of the Willow leaves.
There must be some other reason.
Qin Lin immediately understood the reason.
The special willow leaf duckweed had the property of decomposing and absorbing water pollution substances by +3.
when these special willow leaves were able to break down and absorb the polluted substances in the sewage, there would be a change in the overall, right?
It was just like when a person ate harmful substances. Sometimes, his entire body would turn pale and his skin would turn sallow.
How could the special willow leaf duckweed not be affected at all?
This was definitely the cause of the unusual scene in front of them.
In other words, the special willow leaf duckweed's two +3 attributes were already quickly showing their effects.
it didn't take long for the special willow leaf duckweed in the bucket to turn completely black. in the end, they all rolled up and turned into black balls.
after that, there were no more changes.
"Fish out all these willow leaves," Qin Lin ordered.
A researcher immediately stepped forward and used a sieve to fish out all the special willow leaves that had turned black and rolled into a ball. He placed them into an empty bucket.
But then, when everyone saw the water in the bucket, they couldn't hide the surprise on their faces.
"Look at the water in the bucket. Isn't it much clearer now?" professor Liu asked subconsciously.
"it seems so!" shen li nodded in disbelief.
Qin Lin was sure that the bucket of dirty water was much cleaner.
The bucket of water was completely turbid just now, but it was at least a lot lighter now.
In other words, this was the effect of those special willow leaves.
therefore, as long as there were enough willow leaves floating duckweed, even such heavily polluted water could be purified!
"Quick, re-test the quality of this bucket of water." Professor Liu immediately gave an order to a researcher.
The researcher immediately took the water quality testing instrument and tested the water quality of the bucket.
The TD value rose quickly.
"What was the value of the previous bucket of water?" Shen Li asked.
"It's 1435!" a researcher reported.
This was indeed a very high value, and the pollution was extremely serious.
however, when they re-examined the bucket of water, everyone was shocked when they saw the new td value.
987!
This was the newly detected TD value, which had dropped by more than 400.
"This Gu is too unbelievable." professor liu muttered to himself in shock.
He was a researcher in the field of water plants, so he naturally knew how amazing this was.
There were many plants that had the effect of purifying water, but the effect was limited. Purification was also in a certain sense, and it would take a very long time to slowly recover.
Moreover, the most important thing was that there was a limit to the effects of those plants. Once the pollution reached a certain level, they would be completely useless. They would not even be able to survive in the water. In three to five days, their roots would slowly rot and they would wither.
