Xu Haotian said hello and watched hedgehog drive away.

After dinner in Longyuan, I went back to Lishui bay for the night.

The next day, after sending Xue Meiqi to work, Xu Haotian called Scorpio, and then recently went to Gujing in laonan street.

The ancient well in laonan street is located in the center of Shizi street. Xu Haotian had never paid attention to it before. Today, after inquiring about it, he found it.

Gujing is a pair of Yangyin wells, also known as Shuangsheng wells. In front of Liu's ancestral hall in Shizi street, it is a Fengshui well in the ancestral hall.

Xu Haotian saw that the ancient well had been specially protected. He surrounded it with a barge. Next to it, he set up a stone tablet with white marble. On the stone tablet, he wrote that the ancient well was called Shengshui well. After the three characters of Shengshui well, it was clearly marked with B2 number. The following is a brief introduction to the history of the well.

There are still many people in Gujing who are fetching water. They use barreled buckets. They should be fetching water to eat at home.

Xu Haotian noticed that a manager managed the order of the people who came to Gujing to draw water. He guided everyone to line up and draw water, and reminded everyone to pay attention to sanitation.

"Hello."

Xu Haotian greets him. The manager is a seventy year old man. Seeing Xu Haotian greeting him, the old man looks at Xu Haotian and finds that Xu Haotian doesn't seem to be here to draw water. He frowns and says, "what's the matter?"

"Here, do many people come to fetch water every day?"

Xu Haotian asked, if a lot of people come to fetch water every day, how many people have been raised by this well, and how much impact will it have if Z virus is put into this ancient well?

The old man nodded, "we don't drink bottled water in cross lane. We go here to draw water. The well water is of good quality. It's warm in winter and cool in summer. There are thousands of people who draw water every day."

This bucket of water can be drunk for a week in a normal family of four. Thousands of people come here every day to fetch water. So, there are at least 60000 or 70000 people drinking this ancient well.

Xu Haotian roughly calculated the data. Xu Haotian denied the old South Street. For a city with a population of 10 million, the number of 60000 or 70000 is too small.

If you are a palace organization, since you want to release the Z virus, you should not only focus on these 60000 or 70000 people, but at least 300000 or 400000 people.

In Dongcheng, hedgehog sends Liu Xin to work. He also explores the old well in Dongcheng. The old well in Dongcheng has been closed and covered with thick cement.

Hedgehog visited the old well in Dongcheng. It is said that the old well was dug by fishermen in the past so that fishermen could take water for supplement. A few years ago, people came to take water from the old well, because after a child fell in and drowned, the old well was closed.

After meeting with hedgehog, Xu Haotian drives to the old waterworks, enters the dormitory side of the textile factory, and arrives at the mountain top of the old waterworks. Xu Haotian arrives at the old waterworks.

The old water plant has been completely abandoned. The open-air purification and disinfection pools occupy half of the mountain. Each pool has a number. The tap water of the old water plant has to go through two-stage filtration.

Therefore, the numbers from a to B represent the primary filtration and secondary filtration. Only after the secondary filtration can the water enter the water supply pipeline.

"Boss, there's no point here."

Hedgehog shook his head. The old water plant didn't even have a person left behind to look after it. It was completely abandoned. Therefore, there was no palace organization to look for the old water plant.

Xu Haotian looked at the pool of the old water plant. The water was still full. He didn't know whether it was rain or water. He looked very clean.

"Let's go."

Xu Haotian got a total of five standard areas, and has visited three standard areas. Finally, there are the new water plant and the water diversion pipeline of Yangming lake.

The car slowly drove out of the old water plant and turned to SANLIYUAN Avenue. When Xu Haotian's car passed the vegetable market, he saw Lin Yu sitting on the road. Xu Haotian stopped the car and came.

Hedgehog see Xu Haotian parking, hedgehog also stopped the car, Xu Hao world car, said hello, "aunt Lin Yu."

"Haotian, why are you here?"

Lin Yu peeped out and didn't expect to meet Xu Haotian here.

Xu Haotian gathered up and looked at the dishes beside Lin Yu. Xu Haotian knew that Lin Yu should have bought vegetables in the market, but it was so close that Lin Yu didn't go home, so he sat down on the road tooth. "Aunt Lin Yu, how can you sit on the road tooth?"

Lin Yu took Xu Haotian's hand and looked at him happily. "I'm a little dizzy. I'll sit down and have a rest."

Xu Haotian was startled, "aunt Lin Yu, are you OK, or I'll take you to the hospital?"

Lin Yu shook her head and sent her to the hospital. After she changed her kidney, her physical quality was not as good as before. Now, although the immune drugs have not been broken, people will be a little weak.

"I'm ok. I've just had an operation and hurt my nerves. Now my body is more empty than before. Just have a rest."

"Haotian, you haven't come to see me for such a long time. I miss you so much."

Lin Yu said, mentioned the dish, got up, Xu Haotian took the dish from Lin Yu's hand, sneered, "recently work is a little busy, aunt Lin Yu, I'll take you back."“ Boss Hedgehog waited for a long time, saw Xu Haotian holding Lin Yu home, also put out the fire and got out of the car“ Hedgehog, you go to Yangming lake to have a look first, find out the management personnel, and I'll send aunt Lin Yu home, and I'll follow her in a moment. " Xu Haotian signals hedgehog not to care about himself. He asks hedgehog to go first and send Lin Yu home. It's only about ten minutes. The market is so close that it doesn't take much time. Hedgehog should be a, and back to the car, a person to drive their own first to leave. Xu Haotian was carrying vegetables, and Lin Yu was holding Xu Haotian's hand, just like a mother and son, "Haotian, please advise Lin Bing. She's old and won't listen to me, but she will listen to you." Xu Haotian looks at Lin Yu suspiciously, what does he persuade Lin Bing to do? Lin Bing is going to be engaged. Now she is living a good life. What do you advise her to do“ Aunt Lin Yu, what should I advise Lin Bing? Isn't Lin Bing very good now? " When he came to Lin Yu's home, Xu Haotian put his things on the table. Xu Haotian was just about to leave. Lin Yu took Xu Haotian and sat down, "I'll pour you a cup of boiled water."“ No, aunt Lin Yu, I still have a job. I'll see you next time. " Xu Haotian shook his head, ready to leave, Lin Yu is pulling Xu Haotian, "you sit, I have something to say to you, can't delay you a few minutes." Seeing Xu Haotian sitting back, Lin Yu went to pour boiling water for Xu Haotian and sat down beside him. Lin Yu sighed, "Haotian, please help me persuade Lin Bing to stop being angry." Xu Haotian was even more puzzled. Lin Bing gambled that he was angry. "What do you mean? I heard that Lin Bing is not going to be engaged. How can I gamble with you again?"“ Oh, it's engagement. " Lin Yu shook her head and sighed. She had a headache, which made Xu Haotian look confused.
