After a sleep, Chen Xiansong woke up the next day. Shortly after finishing breakfast, Thier came to him.

He saw the other party's urgency and did not delay. He called Balff and others to go with Thier. Of course, Bai Min was with him no matter what, and did not know whether it was intentional or unintentional. In short, there were many protective personnel in the convoy, with a total of two hundred people. When Chen Xiansong saw this, he immediately thought about whether the other party knew that they had been assassinated twice in Qingxi City.

The carriage was running fast all the way, and Thierl talked slowly with Chen Xiansong in the carriage. He asked a lot of questions about the production of water wheels. Some of Chen Xiansong answered, while others could not answer. The other party was not surprised by this, because Chen Xiansong was still a young man and could not do everything in everything, and the same was true for knowledge.

I arrived at the destination soon. Before I got off the bus, I heard the roar of water. When he got off the bus, he understood why the water truck was built in Diyu City. Because the water difference was too big, it was impossible for the small water truck to deliver the water to the river bank.

There is a big river in front of you, with turbulent water flow and the terrain along the river is dangerous. The ground base is almost full of limestone. It is a bit dangerous to fetch water by such rivers. If you are accidentally swept away, Thierl pointed to a short distance below and said, "It is safest to fetch water there when it has not rained for more than three months."

Chen Xiansong looked over with his fingers. There was a small inner bay with the '4' character. When the turbulent river water arrived, it would be much smoother. Now many people are carrying water up and down along the stone steps. There are three water truck brackets left beside the farmers. The water truck wheel above is gone.

"The problem is that it is a drought period, so you can fetch water like this. But as long as the spring rain comes, even if it is light rain, the water level here will rise a lot. At that time, even the water flow in the inner bay will become very fast. If you are not careful, it will be swept away by the water flow." Thierl smiled bitterly: "Your Excellency, you have also seen that the river bank is full of stones, and the fields are a bit far away from here. The farmers are used to it, but I don't think it's efficient... The fields are close to the river, but it's okay for people to carry water for about one kilometer away, which is not an easy job."

Chen Xiansong knew the reason for building a big water truck, but a river with such a large flow is not suitable for using a water truck. He expressed his questions: "Unless a riverside finds a place where the water balance is found, even if a big water truck that can be used for a long time is built, as long as the water truck rises, the water truck will still use waste instead of the water truck, which will not be built to drain the river, which is more convenient and safer."

"We have thought about this method too..." Thierl stepped on the rock-shaped ground: "But I am a person who specializes in art. I don't know anything about this. No one in our Kate Kingdom knows how to open mountains and dig canals... If it is ordinary sandy land, it's okay to gather people, even if you encounter troubles such as quicksand or pits when opening the canal, you can fill it with your life. But the problem is that most of the land in our Emperor's Recession City is like this rock. If you really want to open the river, you don't know how much manpower and material resources it will cost, and it may not be successful for more than a hundred years."

Chen Xiansong was speechless. He just opened a river channel. It’s not that you want to open a Grand Canal, even if it is a circle river, even if you are ten kilometers long, two meters wide, and two meters deep, you won’t need much manpower and material resources... Do you want to ‘fill with human lives?’ Chen Xiansong has never heard of it before. When opening a river channel, people will die at will... Could it be that he and the humans of this era live on the same earth?

However, after thinking about it again, he realized that posthumans generally lack creativity. They will not have the idea of ​​opening rivers. Soul-thinking people are not gods. They know everything that they have their own specialization direction. What's more, there are very few people who think deeply, and there are too many categories of knowledge in the world. With such a uniform opening, even fewer people understand some unpopular knowledge.

Besides, there seemed to be no chemical explosives at this time, and the iron tools were not hard enough. It would be easy to damage when encountering limestone. Thinking of this, Thierl could not dig a river channel here, it seemed to be excuseful.

Blasting is the best way to rocky terrain. There are many chemical explosives, and there are many that can be used to open mountains and explode rocks... There are one or two ingredients and production process. Chen Xiansong also knows that even if he doesn't know, he believes that Xiao Min's knowledge base also records it, but the problem is that once these things are taken out... the association will definitely hand over it. With the urine properties of intelligent creatures, it will definitely be used in military wars. At that time, massacre will become more efficient.

From the perspective of historical development, this is an inevitable process, nothing more than the difference between early and late, but Chen Xiansong is unwilling to be the one who opened Pandora's box.

Looking at the other party's expectant gaze, Chen Xiansong thought for a while and said slowly: "President Thierre, we can actually think from another perspective. The bronze water wheel is indeed durable, but no matter how durable it is, it will be washed away and washed away as soon as it encounters a big flood. Instead of doing this, we might as well reduce the cost of the water wheel, so low that we will not feel heartbroken even if it is washed away."

Thier seemed to think of something: "You mean?"

"For example, a water truck made of wood" Chen Xiansong pointed to the river surface: "Since it is a drought period and the water flow is so fast, if it rains heavily, the water level will definitely increase. At that time, even more durable water trucks will be washed away. Instead of doing this, we might as well make some water trucks that can be washed away at will."

Thier slapped his head hard: "Look at me, I'm so stupid as a pig, I didn't even think of this." People's thinking is blind. Sometimes, as long as they change their thinking a little, many seemingly unsolvable problems will become a thoroughfare.

"Look for some light but strong, water-resistant logs to make water trucks. I think I can stick to one or two months to make more backups. If the water truck is washed away and install one directly on it, I believe it won't take much time."

Thier thinks this method is very good, and even praises Chen Xian and Song Conghui

After returning to the association, Chen Xiansong was warmly entertained by Thierre and had lunch. Thierre became much more enthusiastic about Udir. He kept praising Chen Xiansong for being an extraordinary talent and a talent that could be made, which made Udir very honored and very happy.

That night, after Udir and Chen Xiansong rested, Thierl wrote a letter in his study, elaborated on what happened today, and then put it in an envelope, allowing his confidant to ride a horse to the royal city overnight and send it to the general meeting.

The next day, when Chen Xiansong and Udir began to set off toward the royal city, the letter written by Thierl had been dismantled by a pair of delicate jade hands.

This is a blond girl with golden eyes. She is extremely perfect in terms of figure and appearance. She is not worse than Bai Min. She finished reading the letter, folded it and put it in a small iron box next to it. Then the letter ignited a golden flame and quickly burned it to ashes. She poured the ashes into the paper scrap bucket beside the table, and then stretched out beautifully, with a curve revealed.

She is the president of the Soul Thinker Association, Artemis

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

Then, she found that Chen Xiansong seemed to have fallen from the sky. The first time she appeared was near Heiyan Town and wanted to investigate, she completely cut off the clues of his inventions, water wheels, and off-season vegetables. These things are actually products from the Pillar of the Sun.

The waterwheel of the Pillars of the Sun has long been famous in all countries, but almost no one knows that there is a very mysterious place in the Pillars of the Sun that specializes in producing some strange things, such as off-season vegetables, and an explosion. The power is comparable to that of the top fire craftsmen, and can explode the hardest rocks with all their strength. The Sun God servant there used this thing, it took only two months to open up a huge underground space and install the entire royal city.

"Under Thierre's intentional guidance, he did not say the idea of ​​using explosives to dig the river!" The beautiful blonde girl said to herself: "Do you really don't know, or are you deliberately hiding it? I understand the confidential information of the Sun Pillar, and there is a sun god servant following her, but she is a soul-thinking person, and can emit green flames. She has gained the trust and love of Minerva. There are so many contradictory characteristics and one body, who are you?"

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

"Camu, go and notify Aisen and ask him to prepare Chen Xiansong's reception work. I believe he will arrive in the royal city within one or two days."

The maid bent down and retreated

Kate's royal city is different from the capitals of other countries. It has no name, it is called "Royal City".

Chen Xiansong sat in the carriage. After two days of hard work, he melted out a new piece of equipment to protect his waist.

Sitting in a shaking carriage, it is not easy to gather your spirits, but as long as you persist, you can gain a lot of benefits. Chen Xiansong felt that his concentration was stronger. When he finished casting the equipment, he found that there was a little noise around him. He opened the curtain and saw a crowded street.

"Is this?" Chen Xiansong asked Bai Min

"You have arrived at your destination now," Bai Min replied in a low voice

The Royal City is the only big city in the Kingdom of Kate that has no walls. It turns out that the royal city also has a wall, but more and more people relocated to the royal city, and the city is becoming more and more crowded. Then the royal family adopted the suggestion of the Soul Association, demolished the city walls and never built them again. Thanks to this, the scope of the royal city became larger and larger, and finally became a giant. It was more than ten times larger than the city on the second day of Kate Royal City. It completely had the size of a medium-sized city in the 22nd century, and the total population reached about tens of millions.

About an hour and a half later, Chen Xiansong finally arrived at the door of the Soul Thinker Association. The royal city is too big. It took a lot of time just to reach the city center from the outside.
Chapter completed!
