The farms in the village are not too far apart, the fish pond is not far from the pigsty, and there is a chicken farm on the right. The fish pond is as big as two acres of land, the grass on the shore of the fish pond is cut clean, and the steps are built with stones to go down to the bottom, and there is a small platform at the water level to spread fish and grass.

There are also people who live close and will come here to do laundry.

Now the whole green pond occasionally has belly-flapped fish floating up, one after the other, which is very shocking.

"Hey, I just cleaned it up in the morning, and this is floating up again." The village party secretary said distressedly, "What the hell is going on?" ”

Lu Shuangchuan walked down the stone steps on the shore, she wanted to see the water quality here, thinking about things, there was moss on the stone steps, she slipped under her feet, and almost didn't fall into it, but a strong arm stretched out next to her and pulled her back.

"Comrade, be careful!" A low and pleasant voice sounded in his ears, startling Lu Shuang.

As soon as she turned her head, she saw Li Xiuyuan's handsome face, and she took a step back, "Thank you, Comrade Li." ”

Li Xiuyuan let go of his hand, lowered his eyebrows, paused, raised his eyes to look at her again, and smiled, "Pay attention to safety." ”

Lu Shuangchuan nodded, walked to the stone platform, and teased the water, and saw that the fish below were about to come up to breathe after swimming for a while, and some of them were not happy to swim up.

She frowned, "Do you smell anything?" ”

"No, isn't this fishpond fishy?" The village party secretary was puzzled.

Li Xiuyuan also shook his head.

Lu Shuangchuan took a handful of water to the tip of his nose, sniffed it, and felt that there was only a fishy smell, but he always felt that something was wrong.

In the previous life, there were also a large number of fish dying in the village, because the technology was limited, and there was no problem. Later, I didn't dare to raise fish here, so it dried up directly, so I had to dig a new fish pond again.

At that time, Fang Pearl had just died, and Lu Shuangchuan didn't have the heart to inquire at all, but she heard her brother mention it once.

"What's wrong? Frost, what's wrong with this water? The village party secretary asked nervously.

Lu Shuangchuan frowned, stood up and looked around, suddenly, her gaze swept over the commune not far away, and a flash of inspiration suddenly flashed in her mind.

She hurriedly stood up and began to look at the pond.

"Comrade Lu, what are you looking for? I can help. Li Xiuyuan said busily.

Lu Shuangjiang: "The last time I saw the excrement of the commune pigsty was discharged through a special pipe, where did it go?" ”

"It's the septic tank next to the fish pond! Is there any connection between these? The village party secretary was puzzled.

"Then let's go and have a look!" After Lu Shuangchuan finished speaking, he took a step ahead.

The village party secretary was still confused, but Li Xiuyuan pursed the corners of his lips and followed, "Comrade Lu, do you suspect that the septic tank is leaking?" ”

Lu Shuangchuan glanced at him in surprise, "How do you know?" ”

"Septic tanks produce gases that can easily pollute water sources. I also saw it from the book! Li Xiuyuan added, "I have always read more books!" ”

Lu Shuangchuan remembered that he later became a manufacturing giant, and said meaningfully, "This may be a good thing!" After all, Baguwen is outdated, learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world! ”

With that, the two went to the septic tank to check, and sure enough, they saw that the septic tank had opened a small ditch, and the fecal water would eventually pass through the fish pond along this small ditch, and it happened that the fish pond had a vent at this location.
