During this time, watching his sons die one by one, crippled, and sick, Xiao Qi couldn't help but feel depressed and uncomfortable no matter how broad-minded he was.

Now hearing such good news, thinking that Dajin can show a sign of prosperity in his hands, his mood is finally relaxed, and the depression that accumulated in his heart some time ago has also dissipated a lot.

Seeing Xiao Qi like this, Qi Xugu also breathed a sigh of relief in his heart.

He took out a fold from his arms and handed it to Xiao Qi.

Because of the accumulation of folds during this time, he will not hand over the folds if it is not very important, and he still carried this fold in his arms before he came, wanting to see if there is a chance to present it to the emperor.

"What is this?" Xiao Yu knew that there was nothing wrong with Qi Xugu, and he wouldn't casually hand him a fold, so he couldn't help but open it curiously to see.

Qi Xugu didn't sell Guan Zi either, and said: "This is because after the minister learned that the farm tools invented by Princess Qi Niangniang played a huge role, he specially sent someone to Nanyang to check the water conservancy situation built by the people who organized Nanyang to serve in conscription before Niangniang left office. ”

When Xiao Qi heard Qi Xugu say this, he knew that this water conservancy must be very beneficial, otherwise Qi Xugu would not have been able to deliberately explain the situation, not to mention that the two farm tools improved by Zhao Ruxi also gave them a big surprise.

He looked at the fold carefully.

This excerpt was written by Qi Xugu and his subordinates with a lot of time and energy.

The water conservancy map of the entire Nanyang area is roughly drawn and marked in some places.

In the text below corresponding to the annotations, it is clear whether an elevated waterwheel was used here or a special construction technique was used to allow the water to pass smoothly in the unfavorable terrain.

Qi Xugu saw that Xiao Qi's gaze moved to the end, and he couldn't help but say: "On this fold, it seems that only a few dams have been built in a few places, and a few more waterwheels have been erected, except for the relatively novel manufacture of waterwheels and the fact that the methods of building dams and canals are a little different, it seems that they are not as good as the water conservancy in other places, and it is not worth talking about." ”

"But if you go to see it on the spot, you will find that this water conservancy system is quite complete, it uses the original streams, canals, lakes, and water conservancy ditches that were built before, and connects and connects them in various ways on the original basis, so that Nanyang has formed a very complete water conservancy system that can be reasonably adjusted by using large and small dams when floods and droughts occur."

"It can be said that with this water conservancy system, as long as there are no particularly large floods and relatively serious droughts, the agricultural harvest of the entire Nanyang will not be greatly affected."

Xiao Qi just read the contents of the excerpt and also had an understanding of this water conservancy project.

He approvingly: "Yes. Although the method is not new, it is rare to have this thought. She only stayed in Nanyang for half a year, and was called back to the capital when she repaired water conservancy in winter, but the water conservancy system she made can benefit the local people for a long time. ”

Zhao Ruxi uses several existing large lakes in the local area as natural reservoirs to store water when the rain is abundant, and can also accommodate as much excess water as possible during floods, so that the whole Nanyang will no longer be affected by floods. And when there is a need for water during the drought, the water from these lakes can be released step by step, so that farmland in various places can be irrigated and urban residents can have enough water for daily life.

The method is not new, but her design is extremely ingenious. It can be said that it took the least amount of money and energy, but the agricultural harvest and safety of Nanyang were guaranteed.

Thinking of this, Xiao Qi sighed with emotion: "Looking at the Great Jin, how many officials can have this kind of ability and ingenuity and the heart of the country and the people?" ”

Officials in ancient times were completely different from modern highly educated talents. They have been studying the Four Books and the Five Classics for decades, learning how to write good policy theories, and many of them are dead readers. Even if you need to use some ways of governing the country to write a policy theory, it is also a cloud of people, the so-called "a big copy of the world's articles, it depends on whether you can copy it or not", so the articles of the champions, lists, and tanhua are the most popular.

After these people were admitted to the Jinshi, they went directly to the post as officials. It's okay to be an official in various departments in the capital, and you can also learn skills from your predecessors before doing things; But those who are assigned to various places to make county orders must understand and grasp all aspects of politics, economy, criminal cases, and agriculture in the entire county, and they themselves are still raw melons and eggs. It's good if there is no chaos, where can you still make some political achievements? Shangguan put a lot of energy on watching them prevent them from making trouble, and he didn't want to think about how to develop the agricultural economy of the province.

Compared with the performance of the previous generations of new science and technology scholars, Zhao Ruxi has only been an official for half a year, and the achievements he has made are quite eye-catching.

Not only is she capable, but it is rare that she has this heart.

When Xiao Qi regretted that Zhao Ruxi could no longer be an official in the future, and when Dajin lost a talent that could be created, he listened to Qi Xugu and said: "Your Majesty, do you know how much silver Princess Qi spent when she built these water conservancy?" ”

Xiao Qi retracted his thoughts and looked at Qi Xugu: "Isn't there a lot?" But it's worth the money. If there is no water conservancy system, how much will Nanyang lose in the event of floods and droughts? ”

"Hahaha, Your Majesty, that's not what the minister meant." Qi Xugu waved his hand and smiled, "What the minister means is that the water conservancy system repaired by Princess Qi not only did not cost a penny in the yamen, but made a lot of money, believe it or not?" ”

"How is that possible?" Xiao Qi subconsciously asked.

However, after asking, he knew that this was definitely the truth, otherwise Qi Xugu would not have said so.

He is the emperor, and his subordinates don't have the courage to joke with him like this.

He perked up and asked eagerly, "What's the matter?" ”

The dams built by Zhao Ruxi cost a lot of cement, sand, manpower and material resources, and the construction and installation of elevated waterwheels also cost money. The money she spent was definitely more than the money spent on water conservancy repairs in Nanyang in previous years, at least one or two times more.

Xiao Qi is an emperor who has worked hard to govern the country, and he knows very well the situation of the yamen below, and he knows the funds used by the yamen at all levels for water conservancy every year. Zhao Ruxi's water conservancy is definitely beyond the budget of the yamen.

He really couldn't figure out why Zhao Ruxi not only didn't spend money, but made money.

"The emperor still remembers the textile factory that Princess Qi originally co-founded with Princess Shangde? The loom she built could be driven by water power. When Princess Qi was building these dams, she talked to Princess Shangde. If the eldest princess of Shangde pays for the dam repair, the Nanyang government can give her a five-year free use period of the dam, and then charge an annual fee after five years. ”
