After a good night's sleep, the next day, Chen Xiansong woke up, and shortly after breakfast, Thiel came to the door.

He saw the urgency of the other party from this, and he didn't delay, beckoned Balf and the others, and set off with Tier, of course, Bai Min was with him no matter what. I don't know if Lu Dao was intentional or unintentional, in short, there were a lot of protection personnel accompanying the convoy, there were two hundred people, Chen Xiansong saw this situation, and immediately thought that the other party knew that Lu Dao was assassinated twice in Qingxi City.

The carriage was in a hurry, and Thiel was in the carriage, talking slowly with Chen Xiansong, and he asked a lot of questions about the production of the waterwheel, and Chen Xiansong answered some of them, and some of them couldn't. In this regard, the other party is not surprised, because Chen Xiansong is still a young man, and it is impossible to do everything in detail, and the same is true for knowledge.

Soon arrived at the destination, before he got off the car, he had already heard the roar of the water, and when he got out of the car and looked, he understood why the emperor was in the city to build a big waterwheel, because the water potential difference was too big, and it was impossible for the small waterwheel to send water to the riverbank.

In front of me is a large river, the water is fast, and the terrain along the river is dangerous, and the ground base is almost entirely limestone. It is inherently dangerous to fetch water by this kind of river, and if you are not careful, you will be swept away. Pointing not far below, Tiel said, "When it hasn't rained for more than three months, it's safest to fetch water there." ”

Chen Xiansong followed his finger and looked over, there was a small inner bay in the shape of '4', the turbulent river water would be much smoother there, and now many people were going up and down the stone steps to carry water, all of them farmers. There are still three waterwheel brackets left on the side, and the waterwheel wheel on top is nowhere to be found.

"The problem is that it's a dry season, so we can fetch water like this, but as soon as the spring rain comes. Even if it rains lightly, the water level here rises a lot, and even the water in the inner bay can become very fast, and if you are not careful, you will be swept away by the current. Tiel smiled bitterly: "Your Excellency has also seen that the vicinity of the river bank is full of stones, and the fields are a little far away from here, the farmers are used to it, but I don't think it is efficient...... People whose fields are close to the river can say that it is about a kilometer long to carry water far. It wasn't an easy job. ”

The reason for building a large waterwheel Chen Xiansong is considered to know the road, but the riverside with such a large flow is not suitable for using a waterwheel at all, and he said his doubts: "Such a riverside, unless it is a place to find a balance of water potential, even if you build a large waterwheel that can be used for a long time." As soon as there is a torrential rain, the water rises. Waterwheels will be used as waste. With its waterwheels. It is more convenient and safe to create a river to drain water. ”

"We've thought about this too......" Thiel stepped on the rocky ground, "but I'm a man of art, and I don't know anything about it." There is no one in our kingdom of Kate who knows how to open mountains and lead canals...... If it is an ordinary sandy soil, it is easy to say, gather manpower, even if you encounter quicksand, traps and other troubles when digging canals. It is also possible to fill in a river channel around the city with human lives, but the problem is that most of the land in our Emperor City is made of this kind of rock. If you really want to open the river, I don't know how much manpower and material resources it will take, and it may not be successful for more than 100 years. ”

Chen Xiansong was speechless for a moment, don't you just open a river, it's not that you want to open a Grand Canal. Even if it is a river around the city, even if you are ten kilometers long, two meters wide, and two meters deep, it won't take much manpower and material resources...... Don't you want to exaggerate 'fill with human life'. Chen Xiansong had never heard of it before, opening the river would kill people casually...... Isn't he living on the same earth as the humans of this era?

But on second thought, he understood. Post-human beings generally lack creativity, they do not have the idea of opening up the river, and the soul thinker is not a god and understands everything. They have their own specializations, not to mention the fact that the number of soul thinkers is very small, and there are too many categories of knowledge in the world, so even if they are even, there are even fewer people who know some unpopular knowledge.

Moreover, there seemed to be no chemical explosives at this time, and the iron tools were not hard enough, so they would be easily damaged when they encountered limestone. When you think about it, it seems understandable that Thiel couldn't dig a river here.

Blasting is the best way to deal with rocky terrain. There are many chemical explosives, and there are many that can be used to open mountains and blow rocks...... There are one or two ingredients and the production process Chen Xiansong is also clear, even if he doesn't know the way, he believes that Xiao Min's knowledge base also has it, but the problem is that as soon as these things are taken out...... After the association knows the Tao, it will definitely be handed in, and with the urine properties of intelligent creatures, it will definitely be used in military warfare, and at that time, the slaughter will become more efficient.

From the point of view of historical development, this is an inevitable process, nothing more than the difference between early and late. But Chen Xiansong is not willing to be the one to open Pandora's box.

Looking at the other party's expectant gaze, Chen Xiansong thought for a while, and said slowly: "President Tier, in fact, we can think about it from another angle, the bronze waterwheel is indeed durable, but no matter how durable it is, as long as it encounters a major flood, it will be washed away and washed away, instead of this, we should reduce the cost of the waterwheel, so low that even if it is washed away, we will not be heartbroken." ”

Thiel seemed to think of something: "You mean? ”

"For example, a watermill made of wood." Chen Xiansong pointed to the river: "Since it is a drought season, the water flow is so fast, if it rains heavily, the water level will definitely become high, and even a more durable waterwheel will be washed away at that time. ”

Thiel patted his head vigorously: "You see I'm stupid as a pig, I didn't even think of that." "There are blind corners in people's thinking, and sometimes as long as you change your thinking slightly, many seemingly unsolvable problems will become a pathway.

"Find a watermill made of lightweight, but strong and water-resistant logs, and I think it will last for a month or two. Make more spare, if the waterwheel is washed away, just install another one, I don't think it will take much time. ”

Thiel thought it was a good idea, and praised Chen Xiansong for his intelligence.

After returning to the association, Chen Xiansong had lunch under the warm hospitality of Tielle. During the dinner, Thiel became much more enthusiastic about Udil, and he kept praising Chen Xiansong for his talent and manufacturability, which made Udile very proud and happy.

That night, after Udil and Chen Xiansong rested, Thiel wrote a letter in the study, recounting in detail what happened today, and then put it in an envelope, and asked his henchmen to ride to the royal city overnight and deliver it to the general assembly.

The next day, when Chen Xiansong and Udir began to set out on the road to continue their march towards the royal city, the letter written by Thiel had been opened by a pair of Qianqianyu hands.

This is a blonde girl with golden eyes, no matter her figure or appearance, she is perfect, and she is not worse than Bai Min. She read the letter, folded it and put it into a small tin box beside it, and then the letter ignited a golden flame, which was soon burned to ashes, and she poured the ashes into the confetti bucket beside the table, and stretched her waist beautifully, showing her curves.

She is the president of the Society of Soul Thinkers, Artemis.

Since she first received information from Chen Xiansong, she has noticed this person, and even sent someone to check his details.

Later, she found that Chen Xiansong seemed to have descended from the sky, and the first time he appeared was near Black Rock Town. If you want to investigate it again, you will completely cut off the clues. His inventions, the waterwheel, the out-of-season vegetables, these things are actually the products of the Pillar of the Sun.

The waterwheel of the Pillar of the Sun has long been famous in all countries, but almost no one knows about it, in the Pillar of the Sun, there is a rather mysterious place, which specializes in producing some strange things, such as out-of-season vegetables, and a kind of thing that can explode, the power is comparable to that of a top fire magician, and it can explode the hardest rock, and the Sun God Servant there, with this kind of thing, it only took two months to open up a huge underground space, which can fit the entire royal city.

"Under the deliberate guidance of Tiel, the idea of digging a river with explosives was not uttered!" The beautiful blonde girl was talking to herself: "Do you really not know the way, or do you deliberately hide it?" Knowing the confidential information of the Pillar of the Sun, and having a Sun God servant by his side, but being a deep thinker of souls, and being able to emit green flames, and gaining Minerva's trust and affection, so many contradictory traits are combined into one, what are you? ”

The girl thought for a moment, rang the golden bell on the table, and a blue-haired female servant walked in.

"Camus, you go and inform Eisen and ask him to prepare Chen Xiansong's reception. Presumably, within a day or two, he will be in the royal city. ”

The maid stooped and retreated.

Kate's Castle is different from other capitals in that it doesn't have a name, it's just called 'Castle Royalty'.

Chen Xiansong sat in the carriage, and after two days of hard work, he forged a new piece of equipment, a waist guard.

Sitting in a rickety carriage, it is not easy to gather spirit, but as long as you persevere, you can reap a lot of benefits, and Chen Xiansong feels that his concentration is stronger. When he finished casting and equipment, he noticed that there was some noise around, and he opened the curtain and saw a street full of people coming and going.

"What is this?" Chen Xiansong asked Bai Min.

"We've arrived at our destination now." Bai Min replied in a low voice.

The royal city is the only big city without a city wall in the Kate Kingdom, the original royal city also has a city wall, but more and more people moved into the royal city, and the city became more and more crowded, and then the royal family adopted the suggestion of the soul association, the city wall was demolished, never to be built again, thanks to this, the scope of the royal city is getting bigger and bigger, and finally it has become a giant, it is more than ten times larger than the city of Kate King City the next day, and it has the scale of a medium-sized city in the twenty-second century, with a total population of about 10 million.

After about an hour and a half, Chen Xiansong finally arrived at the door of the Soul Thinkers Association, the royal city was so big that it took a lot of time to reach the city center from the periphery.

A middle-aged male soul contemplator with gray hair stood at the door, and when he saw the convoy, he greeted him. (To be continued......)
