"What?"

Team Leader Liu didn't react at first, but then he understood.

Gu Yunyang said, "The water source is polluted. Where do you usually get your water from?"

Don't assume that all areas in the city have running water; at least in this alley, there is no running water.

Previously, no one lived in the courtyards of this alley, and the people in the other alleys were unwilling to spend money.

Water pipes aren't entirely free. In some employee compounds, the factory is willing to pay part of the cost, and the residents of the compounds are willing to share the cost.

Then, with the municipal engineering department willing to take on a portion of the work, and the waterworks and other related parties combined, it will be possible to complete the installation of water pipes into the yard.

The residents in this area are currently unwilling to spend the money, so there is no running water for the time being.

Team Leader Liu was taken aback for a moment, then said, "In a well not far from here."

Gu Yunyang asked curiously, "This is a three-courtyard house with only one well. Didn't you draw water from this well?"

A little embarrassed, Captain Liu made an excuse, saying, "After all, they are all children, so I had them all go to the well that the neighborhood uses to fetch water."

Thirteen's expression seemed to change slightly as well.

Gu Yunyang roughly knew that something must have happened here.

However, since Captain Liu didn't say anything and had already restrained everyone, Gu Yunyang didn't say anything more.

Gu Yunyang then asked curiously, "Then what's the matter with these children?"

As Captain Liu led Gu Yunyang out the door toward the well, he said, "A few days ago when I was fetching water, I carried an extra load. I thought to myself that the kids aren't very strong and it would be dangerous for them to fetch water themselves, so I brought it to them."

Well, good intentions gone wrong.

Team Leader Liu probably didn't expect this either.

Gu Yunyang went to check the well in this three-courtyard house, and his wood-type ability indicated that there was nothing unusual about the well.

That means it came from outside.

"This is it," Captain Liu said, pointing to the well.

Gu Yunyang looked at the well, sensed it carefully, and nodded: "This well is polluted."

"Huh?" Captain Liu was startled. "What are we going to do? The residents in this area all rely on this well for their livelihood. They draw water from this well for cooking and drinking."

Gu Yunyang said, "Actually, it's not troublesome. I can prepare some medicine to kill the roundworm eggs in this well. In addition, boiling the water you fetch will also effectively kill the roundworm eggs, so there shouldn't be any problems. Most of you who are infected with roundworm eggs probably drank untreated water, right?"

These days, don't think that people from the countryside don't know this.

Countless people in the city drink untreated water directly.

The water drawn from that well was extremely cold and sweet.

Especially in summer, everyone prefers to drink unboiled water.

On the contrary, in winter, Chinese people like to drink hot water. There is a saying that Chinese people like to say, or that is often mentioned by scumbags.

Drink more hot water.

It is evident that Chinese people prefer to drink hot water.

Gu Yunyang said, "However, I can't directly do the insecticide treatment while I'm preparing the medicine. You have to discuss it with the neighborhood committee. So, after I prepare the medicine, you take it back and discuss it with the neighborhood committee. Then, after you've brewed the medicine, you and the neighborhood committee can pour it down together."

At first, Captain Liu had some doubts about Gu Yunyang, but after hearing what Gu Yunyang said, he began to believe him.

"Okay, I'll go get the medicine. I'll bring it to you later, and you can go with the neighborhood committee to see a traditional Chinese medicine doctor for a check-up before proceeding with this."

After saying that, Gu Yunyang left without waiting for Captain Liu's reply.
