The banquet in the village is nothing more than four large pieces of chicken, duck and fish, which are packed in wooden basins with a diameter of more than one foot and placed on the table. There were more than 20 people and servants brought by Su Hao, plus Wang Tiangui and others who were originally digging wells in the village, adding up to four full tables, which were placed in the empty field outside Cai Youshou's house

Su Hao refused everyone's toast on the grounds that he still had to do things in the afternoon, and also forbade the students and officials to drink. In this way, the whole scene is a lot more gentle.

After eating, Su Hao took everyone to begin to survey the terrain around Caijia Village, as he did in Longkou Village, he not only observed the direction of the hills, but also went down to the abandoned wells to see the cross-section of the wells. The students who came with him followed his example, sat in bamboo baskets, and had them lowered down into the well with wheels to see the soil and rock formations.

These students are not as squeamish as Su Hao thought, and going down the well is more of an exciting experience for them than work. When these people returned to the surface from the mine, their faces were flushed and excited, and they kept bragging about what they had seen and heard in the well to the students who had not yet taken their turn to go down.

The work of Caijiacun station, Su Hao did it as a military training. He asked everyone to go down the well and go around the well, and then explained the rock formations based on the surface landform, analyzing where it is easier to become a water storage structure and which places are not so easy to form shallow groundwater.

"Let's see, this is my hastily drawn topographic map of the surrounding area of Caijia Village, and we guess that there are two structures in this area, and their trends are like this......" Su Hao drew a picture on the paper with charcoal, pointing and explaining to the students, "Let's analyze the content we talked about yesterday, where to dig a well, the possibility of water coming out is the greatest." ”

"This ......" Ma Yu, who was standing beside Su Hao, was the first to speak, and at the same time pointed to a certain place in the map with his finger. is worthy of being the head of the county exam, and his comprehension ability is indeed the strongest among the people.

"Well, this place is indeed an ideal place, let's make it point A." Su Hao used charcoal to draw a mark on the place where Ma Yu pointed and wrote the word "A". If it is put in the future, he must be marked with ABCD letters.

"Let's see, are there any other suitable well locations?" Su Hao continued to ask the students.

The students stared at the map for a while, raised their eyes to look at the surrounding terrain, and they were all recalling what Su Hao had said, and at this time, a crisp voice came from behind Su Hao:

"I think there's probably water here, too."

With this voice, a slender hand reached over and tapped lightly on the map.

Su Hao was squatting on the ground, and when he heard the sound coming from behind him, he turned his head and looked up, and there was a pretty face in his eyes. When the four eyes met, the person behind him hurriedly turned his face away, his face was crimson, and he didn't dare to look at Su Hao again.

"It turned out to be Han ...... Brother Han. Of course Su Hao knew that the other party was Han Qian, who was listening to the class in the classroom yesterday. Although Fang Mengjin covered up for her before saying that her name was Han Qing, Su Hao had already asked Lu Xiuer yesterday, and knew that the daughter of the old man's family in the county was named Han Qian, who was literate and hyphenated, and "very beautiful".

Su Hao still believes in Lu Xiuer's aesthetics, and when Han Qian went to attend the class on the first day, she deliberately dressed herself up not so eye-catching, but Su Hao could still feel her natural beauty. At this moment, the two of them were face to face, no more than a foot apart, and Su Hao could see Han Qian's face clearly. Although he is not a family, he has also heard the term "skin is like cream". He felt that this word was indeed too appropriate for Han Qian.

Han Qian soaked Han Wen for a long time, and only had to wash her face with tears, so she was allowed to go to the countryside to observe Su Hao's well exploration. As a young lady, Han Qian naturally couldn't squeeze into the same car as the students to go to the countryside, so Han Wen arranged for his henchmen to hire a carriage with a tent, so that Han Qian and Yahuan Honglian could change into men's clothes and take a carriage to Caijia Village.

This time, Han Qian was dressed as a student, and Honglian was dressed as a scholar. Of course, it is impossible to hide this dress from everyone's eyes, it is just to cover your ears and steal the bell to seek some psychological comfort.

When Su Hao explained the geological structure to everyone, Han Qian also came to the crowd and stood behind Su Hao to listen. She was also an extremely smart person, and her comprehension ability was no less than Ma Yu, the strongest among the students. After listening to Ma Yu say that the first well position that could be selected, she couldn't help but make a move and pointed out the second well position.

Everyone didn't pay much attention to Han Qian's existence at first, and when they heard her speak, they realized that a stranger had appeared. Listening to Han Qian's voice, and then looking at her appearance and figure, the students would not guess that this person was actually a girl. Everyone couldn't figure out Han Qian's identity for a while, and because of etiquette, they didn't dare to coax, but they all subconsciously took half a step back, not daring to get too close to her.

As soon as Han Qian spoke, she knew that her identity had been exposed, but she had already been mentally prepared for this. As a second-generation official, she didn't take the talents in her eyes, so she didn't care if she became the object of onlookers. She nodded to Su Hao and said, "Brother Su, do you think what I said is right?" ”

"What Brother Han said is very correct." Su Hao said with a smile, and casually made a mark on the place where Han Qian pointed out, marking the word "B".

"Brother Gaizhi, does this mean that if you dig wells in these two places, you will definitely be able to produce water?" Ma Yu asked.

Su Hao said: "From common sense, it should be like this. However, we also need to know that the geological structure is very complex, especially Fengcheng, which is located in the splicing zone of the Yangtze plate and the South China plate, and there are multiple ductile shear zones...... Well, it's good for everyone to listen to this, and you don't have to dig into it. In general, it means that the geological structure of our Fengcheng is relatively complex, and it is likely that there will be a rock fracture somewhere, which will cause the structure we deduced to change. ”

"So what to do?" Ma Yu asked, he had already recorded all the words Su Hao said just now, and planned to go back and think about it carefully, now what he has to do is to squeeze more knowledge out of Su Hao's mouth.

Su Hao said: "There is no good way, it can only be a trial and error method." The wells they have drilled before have provided us with trial-and-error materials, and by analyzing the rock strata below, we can minimize errors and avoid waste. ”

"Brother Su, you mean to say that we can drill wells in these two places first, if the water comes out, then it is enough, if there is no water, we can also speculate the location of the new well through the situation of the wells drilled, is that the case?" Han Qian asked.

"What Brother Han said is extremely true." Su Hao replied.

"Okay, let's go and fix the well now." Ma Yu said excitedly that although the deduction of the geological structure was completed by Su Hao, this was after all some knowledge that he could understand. For the first time in his life, he used science and technology to do something, which was a feeling of rebirth for Ma Yu.

"Master, can you take a step to speak?" Chen Guanyu, who had been standing next to him and listening to the discussion, stepped forward and gave Su Hao a look.

Su Hao's purpose in bringing Chen Guanyu was to let him deal with some things outside of technology, seeing Chen Guanyu's mysterious look, Su Hao said hello to the sentient beings, and then walked to the side with Chen Guanyu.

"Lao Chen, what do you say?" Su Hao asked Chen Guanyu.

"Master, Xiaodao just listened to the master's explanation of this groundwater, and felt a sudden opening. In Longkou Village, Xiaodao was defeated by the master at the hands of the master in the survey well, which was really convincing. Chen Guanyu said.

Su Hao was surprised: "Lao Chen, you asked me to speak alone, just to praise me?" ”

"No, no, no." Chen Guanyu hurriedly said, "Xiaodao is just talking about his thoughts. I asked the master to take a step to speak, I want to suggest to the master, the two wells just selected, it is best to choose place B first, in case there is no water in place B, and then choose place A, what does the master think? ”

"Why?" Su Hao asked, "Judging from the comparison of these two places, the structural characteristics of water storage at place A are more obvious, and the structure at place B is somewhat unclear. It is safer to dig a well in place A. ”

Chen Guanyu whispered: "Xiao Dao also knows this, in fact, at noon, Xiao Dao has already asked the feng shui master who is surveying the well here, he has also chosen this place before, but then gave up." ”

"Why?" Su Hao asked again.

"This place happens to be next to the ancestral grave of the Cai Li family...... Chen Guanyu said meaningfully.

"Damn!" Su Hao issued a 21st century interjection, "Lao Chen, are we considered to be short-handed?" ”

"It's convenient for others and for yourself." Chen Guanyu said, "Besides, Cai Lichang is also a bit of a powerful person, and he told me that he has a relative who is an official in Beijing. I thought, since we have two points to choose from, why do we have to choose point A first? ”

"That's fine." Su Hao gave in, anyway, there may be water in both places, but there is really no need to offend Cai Youshou. The people gave themselves five taels of silver in advance, and it is estimated that they also expected this result.

Thinking of this truth, Su Hao returned to the students and said to everyone:

"Guys, let's go and see the well now. Just now, Mr. Chen calculated and said that Brother Duwen's fancy A is related to the leyline feng shui of Caijia Village, and the younger brother means that for feng shui, we would rather believe in it than believe in it. Anyway, there are two wells, A and B, so let's try to drill a well at B first. ”

"Let's go, let's take a look." The students didn't have any opinions, and they all said noisily. They saw that Chen Guanyu was indeed dressed as a Taoist priest, so they believed the explanation given by Su Hao.
