After a while, Rong Bai pointed out seven or eight mistakes on the map. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"It turns out that the maps on the county records are not all correct. After listening to Rong Bai's correction, Tang Yu couldn't help but sigh.

His map was drawn according to the records of Linjiang County. Apparently, there is a problem with the county chronicle.

"The map of the county chronicle?" Under Hengqing's explanation, Rong Bai knew what the county chronicle was. It is also clear that this thing is generally impossible to go wrong. "When is the map?"

Tang Yu thought for a while: "About five or six hundred years ago. ”

Rong Bai has a black line, but he didn't expect this county to be a county with a long history. However, can topographic maps from five or six hundred years ago be used now?

The earth's crust is moving, and it is normal for small hills to turn into cracks five or six hundred years ago.

"That topographic map shouldn't be useful if you don't modify it. What are you looking at this map, is there going to be a war?" asked Rong Bai.

In the last days, once the map is taken out, there will definitely be a war, either against the beast or other bases.

"I want to find a source of groundwater. Tang Yu shook his head.

I originally thought that the work of finding groundwater would not be so difficult, but I didn't expect that the three who went to suppress the bandits had indeed drilled wells. But in the process of digging wells, these are just coolies. The one who is really looking for water is an old man.

Even more unfortunate, this old man suddenly fell ill and died a few days ago.

As the most important person in the town, Tang Yu had to start learning the skills of finding water. There is really no way for one person, so he dragged Hengqing, who is also talented, into the water.

Rong Bai looked at the map that Tang Yu had brought, and she could see at a glance that Tang Yu was looking for the water source. It is the river where the spring where he draws water now.

According to Rong Bai's understanding, in fact, in addition to the surface river, Linjiang County also has an underground river. There is no junction between the two rivers. So no matter how hot the weather is, the surface rivers start to dry up, and the underground rivers are not even affected.

For example, the source of the water used for the spring water has not changed. Another example is that the well water in the house in the county has not dried up.

"It's a really good water source. However, too far from the surface. Rong Bai frowned and replied.

That's right, the river was too far from the surface, and the only place near it was the spring in the back mountain. The well rope of the house in the town was seven or eight meters long.

"Do you know where the water source is?" At this time, not only Tang Yu, but also Hengqing became excited.

Rong Bai nodded. Looking at the map, he drew two dots on it with his fingernails: "The other places, I don't know, these two dots should be the places where the underground river flows." ”

The location of two points in Rongbai, one is the location of the spring on the mountain, and the other is the location of the new home in the south of the town.

Two points can determine a straight line, but rivers rarely flow in a straight line, and this is especially true for underground rivers. Therefore, even if Rong Bai determines two points, he cannot determine the direction of the entire underground river.

"Unfortunately, there are only two points. ”

Tang Yu looked at these two points and let out a long sigh.

Rong Bai looked at these two people like an idiot, there were only two points there. How many people in the county have well water at home. Send people from house to house to see if there is water in people's wells, don't you know the general direction of the river?

"Xiaobai, how do you know that there is an underground river here?" or Hengqing reacted first, pointing to the point that Rong Bai left in the city.

That point on the mountain should be the spring where they get water. And how did that spot in town find out?

Rong Bai glanced at Hengqing with satisfaction, and then looked at Tang Yu with disdain, before he said slowly: "This is the new home I chose for us." Many people in the town have dried up their wells, but this well is still usable. However, the well was very deep, and the rope was twenty or thirty feet long. ”

Rong Bai paused, and replaced seven or eight meters with a unit of length that they could understand.

Both of them were stunned, the well was twenty or thirty feet deep, which fundamentally eliminated the possibility of drawing a large amount of water for irrigation.

As a result, this method still cannot be irrigated.

The disappointed expressions of the two people were all in their eyes. Indeed, it is true that the groundwater is not easy to get out of at such a deep level. But for Rong Bai, this is not a big problem.

"Hengqing, tomorrow we are going to move to the town, what things do you want to bring, you can pack up. In a few days, Rong Bai has already renovated the house over there. Totally ready to stay.

"Okay, thank you Xiaobai. Hengqing nodded.

It was Rong Bai who sent Tang Yu out, Hengqing had been sitting on the chair for a day, and his body was a little unbearable.

The drought has made this world lose a lot of life, Rong Bai walked next to Tang Yu, and the two of them didn't say a word until the ferry.

Now the river in Linjiang County has dried up, and there is no need for a boat to cross the river. Rong Bai stood by the ferry, looking at Tang Yu who was walking towards the other side of the river.

Tang Yu's steps were heavy, and every step he took seemed to be dragging thousands of catties of things. An aspiring literati is really powerless in the face of such a situation.

Looking at Tang Yu like this, Rong Bai thought of Hengqing. If Hengqing can also walk, in the face of such a situation, he should be so powerless.

"Flowing wind. Rong Bai suddenly called.

Tang Yu turned around and looked at Rong Bai, who was still standing on the dock.

"If you can find the direction of the river and make a suitable borehole, I will help you divert the groundwater. Rong Bai promised.

She didn't know why she was so promised, obviously the life and death of everyone in this county had little to do with her, but this action exceeded reason.

Tang Yu looked at Rong Bai and suddenly knelt down: "If Mrs. saves Linjiang County with this move, he is willing to go to the soup for Mrs. ”

Rong Bai was stunned.

Didn't she just say one more word, how could this be the result? Besides, this person is too strange, even if Rong Bai's behavior saves people from a county, what does it have to do with him?

Without waiting for Rong Bai's answer, Tang Yu stood up and left without looking back.

This time, the pace was noticeably lighter. Rong Bai shook his head, the brain circuits of people in this world are strange, and Rong Bai said that he really can't understand it, so he will put it there.

Moreover, since he promised to find a way to let the water source come out of the ground, Rong Bai must do it. In fact, the process is not difficult, the main structure, Rong Bai has been tested in the small courtyard of his new home.

When he returned home, Rong Bai saw that Hengqing had not slept yet. Tang Yu's map was not taken away, Hengqing sat at the table, looking down and frowning.

Hengqing is not as pessimistic as Tang Yu, since the underground river has a place on the mountain where the ground is exposed, then other places cannot say that there is such a possibility.

Therefore, the goal of Hengqing is to find the closest location to the ground, find there, dig a well, and meet everyone's requirements.
