It is said to be a large cylindrical pool, but in fact, the water capacity inside is not much worse than that of a narrower and shallower river.

In order to make Chen Shuisheng's own son live more comfortably, when rebuilding the closed factory area and expanding the capacity of the entire pool, Chen Hao specially asked the construction team of the contracted project to dig the pool down to a depth of 20 meters.

In addition, the diameter of the pond has expanded from more than 20 meters to 100 meters wide, and the amount of seawater poured into the bottom is even more.

It was so deep and dark that even if it was illuminated by the high-power light from the roof of the factory, it could not reach the bottom of the pool at once.

No way!

Who made the water dirty and muddy?

Coupled with the black water of the Feiyun River, the water quality here must not be much cleaner than the inferior Class V river water of the Wenruitang River.

It's just that this dirty pool water is about to become a thing of the past by today!

Because as Chen Hao put dozens of [desewage weeds] into the pool, strings of small bubbles visible to the naked eye began to gush up from the pool.

"What is this?"

"The aquatic weeds are already working?" Chen Hao settled down and began to carefully observe the changes in the pool.

I saw that the surface of the pool water, which had become calm because of Chen Shuisheng's deep dive, actually began to inexplicably have dozens of bubble bubbling spots.

If these bubbles were big, it would be fine, Chen Hao thought that Chen Shuisheng was spitting bubbles under the pool.

However, these bubbles are obviously the same as Coke soda, small and dense, and the position of the bubbles coincides with the [desewage weed] that is dropped.

This made Chen Hao have to cheer up and pay attention to it wholeheartedly!

Because of how strong the decontamination and water purification effect of the newly released [Sewage Removal Grass] is, even Chen Hao himself is a little uncertain.

No way!

Who let the [Sewage Weed] just be born in the hands of the turtle?

Its own water purification effect, as well as the entire water purification process, even Chen Hao, a cultivator, could not figure it out.

It is precisely because of this that when Chen Shuisheng dived to the bottom of the pool to help observe, Chen Hao also took a waterproof action camera and tied it to one of the other party's tentacles, so as to take some pictures of [Removing Sewage Grass] working at the bottom of the pool as a reference.

"Aquatic, what's going down there?"

"I see a lot of bubbles on the pool, are these bubbles coming out of the aquatic plants?" Chen Hao began to communicate with Chen Shuisheng, who had dived to the bottom of the pool, through the [Electrocardiogram] skill.

"Baba!"

"It did come out of the aquatic weeds, and there were a lot of bubbles at the bottom of the pool. ”

"These aquatic plants are amazing!"

As soon as he took root, he began to spit bubbles, and sucked up a large amount of ash and mud in the water. Chen Shuisheng replied with a milky voice.

As a giant octopus that has mutated and evolved, Chen Shuisheng naturally still retains the ability to observe with the naked eye under dark water, otherwise Chen Hao would not have given it the task of underwater observation.

It's just that in addition to the other party's ability to conduct normal visual vision underwater, the most important thing is that Chen Shuisheng is a marine creature and has a keen sense of water changes.

This is the same as many domestic pet fish, a slight temperature change in the fish tank, or a disturbance in the PH value of the water body, will cause a large number of pet fish to get sick and die.

Of course, the fragile vitality of these pet fish must not be compared with Chen Shuisheng's sea monster.

Because the latter has already possessed a strong physique to survive in any sea area on the earth through the catalytic mutation of the [Fish-Man Bloodline] of the turtle several times.

Not to mention soaking in the heavily polluted inferior Class V water all day long!

Even if it is the Mariana Trench with a depth of 11,034 meters, throwing a piece of glass into the extreme sea area that can crush you into powder, Chen Shuisheng can go for a walk as easily as taking a walk after dinner.

Of course, after Chen Hao opened the [Fishman Bloodline], he could also come and go in complex waters as easily as Chen Shuisheng.

It's just that after smelling the unpleasant smell in the pool that made people's stomach acid tumble, Chen Hao still dispelled the idea of going into the water himself.

After all, he didn't want to ruin his appetite for eating all day because of a single trip to collect product data (a bit of a stretch).

......

"As soon as it takes root, it starts to absorb dust and floating objects in the water body?"

"It's only been a few minutes!" Chen Hao listened to his son's feedback, and began to sigh in his heart.

You must know that if ordinary aquatic plants want to achieve such a strong adsorption capacity as [sewage weeds], they must be put in a large area in bundles in order to achieve the same effect in a short period of time.

Take the grass tank that players raise every day, even if it is an ordinary small tank with a length of tens of centimeters and width, dozens of aquatic plants must be put in at one time to maintain the cleanliness of the water in the fish tank.

If it is converted to the 100-meter-long super large pool in front of you, then it is not necessary to put thousands of ordinary aquatic plants together to have an effect!

But what about the amount of [Sewage Removal Grass] put in by Chen Hao?

Less than 100 plants!

It's like using this big pool as a fish tank at home!

Of course, the size of these [sewage weeds] is much larger than those aquatic plants in the fish tank, and the shortest adult [sewerage weeds] of a single adult can reach 1 meter tall.

It's just that even if the height of the [Sewage Removal Weed] can reach 1 meter, in this huge pool with a depth of more than 30 meters, it is still obvious that it is a little small.

However, the water purification ability of [Sewage Grass] did not disappoint Chen Hao.

Because at the same time that the turtle was paying attention to the string of bubbles rising on the surface of the water, the surface of the pool, which was originally turbid and blackened, unexpectedly appeared to precipitate.

What is precipitation?

That is, you take a glass of water filled with sand and shake it, and when you stand there, you can see that the muddy sand that was originally scattered and floating in the water body begins to sink slowly to the bottom of the cup one by one.

The large circular pool in Chen Hao's eyes is experiencing this similar precipitation phenomenon at this moment.

It's just that this kind of turbidity precipitation is not because the pool water is static. After all, there is a sea monster Chen Shuisheng churning under the pool, and it is very difficult to make the pool water still.

So why does turbidity precipitate occur?

It's not because those dozens of [sewage weeds] began to frantically absorb the free dirt in the pool water!

You must know that these [sewage weeds] have transplanted more than 500 water purification genes of different strengths at the very beginning. In addition, the adsorption capacity of heavy metals such as 200,000 times the arsenic of the aquatic plant parent [kidney fern].

As soon as it is thrown into the water body to work, the heavy metal elements scattered around it, as well as the dust and pollutants visible to the naked eye, seem to be sucked by a black hole, and begin to rush frantically to the stems and leaves of aquatic plants.
