Therefore, Chen Xi recently found that his command execution ability has increased significantly by one quarter. He didn't react at first, but later he understood it. However, after thinking about the lazy time problem caused by different execution ability in the two situations, Chen Xi decisively chose Fengping to be killed.

Anyway, the rumors are just that. Chen Xi is not worried at all. He is enough to know who he is. If Fengping was killed or something, the group of people would not dare to come to him to say it, let alone what the black spots are afraid of. That is, those wealthy families know that the common people are still the Dragon Prince and the nine-tailed white fox with a bumper harvest, and they don’t care at all.

What's more, Chen Xi was very satisfied with the huge increase in execution. The shocking effect was really good. In the past, because of his weak temperament, although due to his ability, the group of people still followed him obediently, but every time he was a bit procrastinating.

In this situation, these people were probably full of thanks for Chen Xi's mercy and would never dare to delay again. This is really great.

"How much has your design been completed?" Chen Xi didn't want to bother too much about this matter. He naturally returned to water conservancy design. Wang Yan has the ability. Speaking of which, if it weren't for the guaranteed ability, Chen Xi wouldn't have chosen him because of Liu Yan's recommendation.

"I already have an idea, but the problem of water seepage is no longer a problem. The problem is that when precipitation increases greatly, the river water rises and then flows back into Chang'an City." Wang Yan said quickly.

"Continue." Chen Xi said with a calm expression, he had already had some impression.

"The general method is to use a floating valve driven by water pressure. When the water volume outside is too large, the floating gate valve is pressed to the water inlet, and then the water inlet is closed. When the water volume is small, the floating valve is pushed open again with the water pressure inside." Wang Yan roughly explained his design, but it was obvious that Chen Xi was worried that he would not understand it.

"I almost understand how it was done." Chen Xi nodded. He had seen this design when he was flipping books before. Although Wang Yan is just a way of thinking now, it will not be difficult to complete this way by cooperating with his group of people.

"Will the fountain be built?" Chen Xi suddenly asked.

"Yes!" Wang Yan was stunned at first, then nodded and said.

The Central Plains' research on fountains is actually quite average. However, Greece and Rome have conducted very in-depth research on this, so that sometimes some fountain facilities can be dug out when digging Roman ruins. The Central Plains' always pays attention to the natural flow of water, so although the fountain skill is pointed out, it is not used much.

"Cultivate it into a rosy spring." Chen Xi thought for a while and said, "Build a fountain in the middle of the lake where the water is diverting. It doesn't need to be too big, it just needs to be visible."

Wang Yan thought about this thing that he could still make. The fountain with no additional power was more about structural design and terrain. It could lead to water transfer to show that the terrain was already in line with it. Next, we have to work hard on structural design.

This is a bit troublesome, but it is not impossible to complete. The fountain in Shanglinyuan has a design drawing, so you can change it at that time.

"Okay, you want to do better in this industry. I support it here, but you can finish what you have at hand first." Chen Xi waved his hand and sent Wang Yan away.

It is natural for people to want to climb up or something. Chen Xi also likes such a motivated guy. As long as he is capable, Chen Xi doesn't mind helping him, but he does all his own work and wants to climb up, which is really a waste of time.

Wang Yan nodded repeatedly after hearing this, saying that he would solve the matter as soon as possible when he went back.

"Hug Dad~" After Wang Yan left, Chen Xi was flipping through books in the study alone, and then a small head came in from outside the door. When he saw Chen Xi, he shouted in a slight voice.

"Yu'er has another section." Chen Yu rushed in from outside the door staggeringly, then hugged Chen Xi's calves, and Chen Xi also put down his book and hugged Chen Yu. When he was giggling, he kissed him fiercely on the face.

"Husband." Fan Jian stood at the door and bowed to Chen Xi, but did not come in.

"Jian'er." Chen Xi smiled and waved to her. Women were generally not allowed to come in in the study, but Chen Xi didn't care much about this.

"Boyan has sent an invitation." Fan Jian took out a vermilion invitation and handed it to Chen Xi and said.

"That boy said he got married. After talking for so long, he finally got married. Is there nothing happening in the Zi family?" Chen Xi opened the invitation to the wedding banquet and asked with a smile.

"There is no problem for the Zi family to marry Mr. Yan Fang's granddaughter. It's just that I have to wait another year. Mr. Yan Fang is a little annoyed by his family. He thought that his husband and Mr. Jia had ruined his tutoring for several times." Fan Jian said with a smile.

"We are going to ruin the tutor of Zi's family, why didn't he say that Zi's family has such a personality?" Chen Xi rolled his eyes and said.

The Lu family of Fanyang is a descendant of Lu Yu, one of the five major clans in later generations. Although there were few prime ministers, there were more than 800 officials in the family in history during the Tang Dynasty. This is the foundation laid by Lu Yu from scratch. Do you really think he is a little white flower?

Chen Xi didn't believe this, not to mention that Wang Lie himself has the ability to see through the other party and then teach according to his aptitude. If he really doesn't know what Lu Yu is, he wouldn't have handed Lu Yu over to Chen Xi to discipline him after he talked with Chen Xi.

To be clear, Wang Lie knew what Lu Yu was suitable for, at most he felt that this method was too dark, but compared to following him, Wang Lie did not choose to restrain Lu Yu in the end.

"The Zi family is pretty cheerful." Fan Jian pointed his face with his fingers and said.

"Well, the personality is actually not bad." Chen Xi nodded and said, "By the way, have I asked someone to make a globe?"

"It's done, but it was borrowed by the Gan family in Moling and the Shi family in Hanoi." Fan Jian sighed and said. She had gone to find a craftsman, but the answer given by the craftsman was that she was stolen by the two families.

"Make a replica. God knows what those two families are doing recently." Chen Xi said speechlessly. Since using natural colorless crystal to open an astronomical telescope, these two families have been completely immersed in the research of astronomy. The Wang family of Lujiang, Chen family of Jiujiang, and Zhou family of Brazil have also been poisoned. Now this group of people are said to be preparing to build an observatory.

"Let's treat the disease." Fan Jian thought for a while and said, "Many people in these two families are blind. Recently, they have been in Chang'an City. I heard that they think the land price in Chang'an is too expensive and not high enough, so they are planning to find a high place to build an observatory."

"Oh, where did you choose in the end?" Chen Xi asked curiously. He was used to blindness and something. Even if Hua Tuo implanted some kind of ink-colored anti-light things on this group of people, he could not withstand the group of people looking directly at the sun with a large astronomical telescope. At most, he could last longer.

However, no matter how long it lasts, it can't stand the work of these people. They have to study the sun every day, and because of the so-called change and unchange, they have to look at it dynamically. It is normal to be blind.

"Moling and Hanoi." Fan Jian said with a chuckling. Chen Xi rolled his eyes when he heard this. To put it bluntly, hasn't this become the result of the separation of the two families?

"By the way, do they have the money to build this thing?" Chen Xi asked curiously.

"They borrowed some from other families. Speaking of which, these two families usually don't pay back the money, but everyone likes to borrow money for them." Fan Jian said after thinking about it.

Chen Xi nodded. He could understand why these two families could borrow money from other families without paying back the money. The calendar is really natural and stands on the top of all families. It is too high-end, elegant and upscale.

Chen Xi didn't know that in the end, the Gan family and the Shi family built the observatory on Mount Tai. There was no way, money could be borrowed, but only one piece of the super-large colorless crystal was dug out.

The other large colorless crystals I have obtained have some cracks or flaws. There is only such a truly qualified colorless crystal, so one can only be built, even if the two families beg their grandfather and grandma everywhere, hoping to dig out another piece and never get together with another family.

However, due to the reality, the crystal mine cannot dig out the large colorless crystal you want. Such a large super giant crystal suitable for lenses is only one piece. It is completely impossible to want a second piece. Both sides opened several mines, but they could not find a bigger one.

In the end, I could only build an observatory with my nose. In order to ensure the consistency of the distance between the two sides, I chose Mount Tai, so there was another observatory on Mount Tai that has passed down through the ages.

By the way, even though these two companies later created more accurate calendars and planetary movement rules, they could not get a larger crystal.

"It's okay, nothing big happened. Let's make another globe." Chen Xi didn't have the idea of ​​finding those families. Although it would definitely be possible, such a thing doesn't make much sense. If you like it, just give it to those people.

In fact, when Chen Xi talked about the globe, the Gan family was working with the Shi family to study the globe. Both sides have calculated that there is a ball under their feet, but because of brain and common sense, they have never understood how they stand on such a ball.

Until they got the globe now, looking at the rivers, lakes and seas above, and the distribution of the earth, they suddenly thought of something even more strange.
