Chen Xiansong was also a little surprised when he heard Udil's words: "Except for the Sun Temple, there is no one else who knows the manufacturing method of the Ludao waterwheel?" ”

Udir shook his head and said, "Not really." We only know that the Sun Temple has this kind of tool, they have tens of thousands of acres of fertile land under their name, and they only need a hundred or so of these waterwheels to irrigate it, and they don't need many people at all, and our Soul Thinkers Association has always wanted to get this kind of technique, but the Sun Temple prohibits outsiders from approaching their waterwheels, and we don't even have the opportunity to imitate it. Although the world says that our Soul Thinkers Association can be compared to the Sun Temple, in fact, we know very well that at least in terms of knowledge, we cannot compare with the Sun Temple, which inherited the ancient magical civilization. ”

Chen Xiansong originally thought that such a 'simple' thing as a waterwheel should be available in this era, but he didn't expect that it would be a unique monopoly technique. He thought for a while and said, "I will, and so will Xiaomin, but ...... The trouble lies in the material and production process, if it is a simple wooden waterwheel, the overall structure will be slowly blistered and soft, easy to damage, the use time is not long, I heard that there is a waterproof paint, which can prevent solid wood from being corroded by the tide, such a waterwheel can be used for a long time, but the problem I don't know the formula of the waterproof paint. If it is a metal waterwheel, the rust resistance is difficult, you can use bronze, although it will also rust, but the rust resistance is much stronger than iron, and the grinding technique of the metal bearing shaft is also a problem. ”

"Child, you can rest assured." Udir hurriedly said: "As long as there are drawings, our craftsmanship is definitely no worse than that of the Sun Temple, and there are not many associations, but there is more money and more people." What the Sun Temple can do, as long as we know the principles of the Dao, our association can also do it. ”

Chen Xiansong thought for a while and said: "Then we provide the drawings, and the association will help us build two copper waterwheels with a diameter of about two meters, which is considered a drawing fee, and we don't have a foundation in this area, can the teacher help us fight for it." ”

Udir slapped the table vigorously: "Don't say two, two hundred are no problem, as long as you can get the drawings." ”

In Udier's opinion, two copper waterwheels are nothing, even if there is no problem in building two golden waterwheels, he feels that his students' requirements are too petty. As a contemplative of the soul who specializes in agriculture, he will never let go of the skills and knowledge in this area. Although he hadn't seen the watermill with his own eyes, he had seen similar accounts in the Great Library of the General Assembly before, and from that time on, he had hoped that Black Earth City would have a few of these fascinating things.

Chen Xiansong gestured to Bai Min, who went upstairs alone.

Udir fidgeted a little, his eyes full of expectation, and Robert was happy for his master, and at the same time secretly amused in his heart. He has been with Udier for at least thirty years, since the master has grandchildren, he has rarely been happy, has always been an elegant style, but he didn't expect that after His Excellency Chen Xiansong came, he saw the master's gaffe several times, especially the sip of tea just now, which was too distinctive.

Chen Xiansong wanted to chat casually with Udier, but the latter's mind was always upstairs, and he looked at the entrance of the corridor from time to time, not knowing what the other party was talking about and what he was talking about. Seeing this, Chen Xiansong had no choice but to give up. About twenty minutes later, Bai Min came out of the upper building with a few parchment rolls, and when Udir saw her, Huo De stood up, but after thinking about it, he sat down again.

Bai Min first gave the drawings to Chen Xiansong, and then he gave the drawings to Udil.

Udil's rough hands held the drawings, as if he was trembling slightly. On several drawings, there are several cross-sectional structural drawings of the waterwheel, as well as detailed data. Udir wasn't a craftsman, he couldn't read it, but judging from the detail and accuracy of the drawings, it was definitely genuine.

"Kid, I'll take this drawing with me first." He carefully placed the parchment roll in his pocket, and then asked, "If you have any other requirements, just mention it, and I will apply to the association for you." ”

Chen Xiansong said: "There is nothing else needed, won't the teacher stay for dinner?" It's rare to come over once. ”

"Not today, but there will be opportunities in the future." Udir patted the pocket where the sheepskin drawings were stored: "It's still important, the sooner it is implemented, the sooner the Black Earth City can be used, and I feel much more at ease." Child, as soon as you came to our Black Soil City, you first proposed the concept of ecological agriculture planting, and then gave the association a blueprint of the waterwheel, but our association has not given you anything now. It can be seen that your desire for money is not strong, and if you are powerful...... The status of our association is a bit transcendent, power is not our core, we can't give you any help in this regard, you can only fight for it yourself, women ......" He glanced at Bai Min: "I don't think you need it much, as soon as this drawing is handed over to the general association, I think the reward for you will come down soon, during this period, you have to think about it, what do you want!" ”,

After saying this, Udil left in a hurry, and Chen Xiansong sat in his chair and thought about this question. Since he was a child, he has been well taken care of by Sister Bai and the new humans around him, he has never worried about food and clothing, and he doesn't feel that he lacks anything. Some philosophers have said that human greed and desire are mainly produced in two aspects, survival instinct and comparison; The former is easy to satisfy, while the latter is the inferior nature of human beings.

But the problem is that Chen Xiansong doesn't even have a comparison object, natural people are originally national-level figures in the new human era, and natural people of the same age as him have never been in contact. And now...... And the post-humans of the dark civilization, what is there to compare!

Therefore, he didn't know what he needed, and after thinking about it for a while, he felt that it was not the way to think about the problem alone, so he went to ask Xiao Min, who looked at him quietly with cold eyes for a while, and said, "Knowledge and ability." ”

Then he went to ask Alex, and the little guy only shook his head in the face of the teacher's inquiry.

Next, he also went to ask the mercenaries such as Balf who were resting on the bed, Aslan, these people all shook their heads in unison and said that they didn't know what to say, they didn't dare to give Chen Xiansong any advice, the other party was a soul thinker, what are these people, civilians without any knowledge.

Only Xiao Min gave him an answer, but this answer had little to do with Udil's question. He thought about it, or decided to think about it later.

Zeloner sat in the study, looking at the information that Verder had gotten: "Oh? Howard ended up hanging out with Comos, which is interesting. Comos is a man I know that he was a hypocritical bastard when he was a child, a gentleman on the surface, but in fact his conscience has already been sacrificed to the devil, no matter what Howard intends to do, he will definitely be 'sold' by Comos afterwards. Is there any other information? ”

Verde thought for a while and said, "I don't know if it's intelligence, Howard recently asked someone from the Mercenary Guild to go to the forest to pick a lot of fluorescent grass, night star grass, and ice insect shells. ”

Ze Long'er frowned, "Night Star Grass and Ice Worm Shells are mixed together, ground into powder, and have an aphrodisiac effect. Howard's target should be Chen Xiansong's bastard, are they planning to stun Bai Min? Use this method to fight Chen Xiansong? That's where it gets interesting. ”

When Verde heard this, he clutched his knight's sword tightly with his right hand: "They are killing themselves!" ”

"Calm down. This is just speculation. Zeloner said slowly: "Howard's idiot may do this, but if Comos is involved, it is unlikely, and there is a lot of fluorescent grass in it, the effect of fluorescent grass is to cure diarrhea, what kind of effect will the three things be mixed together...... Why don't we try it first? ”
