"Patrolling the fields?"

Hearing Xi Zhicai's response, Cao Cao couldn't help but pause.

Only then did he remember that although he had let Xi Yu serve as the chief historian, he had not canceled the duties of the other party's Tuntian Lieutenant.

At present, the other party is indeed responsible for the affairs of the field.

However, after more than a year of understanding, I also know more or less what kind of character the other party is.

In addition to disliking military positions, Xi Yu is usually a little lazy.

Sometimes, it's more than Xi Zhicai.

After the end of Tuntian, other people can rush back in two or three days, and this guy can walk back for more than half a month on the road.

Of course, it's definitely no problem for Xi Yu to do things.

"Fengyi went to inspect the fields?" Cao Cao grinned: "This is curious!" ”

"Fengyi said that as the captain of Tuntian, he naturally wants to ensure that the grain and grass are safe, and during this period of drought, he also said that let the water come and irrigate the fields!"

Xi Zhicai casually blew his brother.

As soon as he said this, not only Cao Cao, but Xun Yu on the side also raised his head.

Let the water come to you? Irrigate the fields!

How can water come from itself?

Seeing the expressions of the two, Xi Zhicai also shook his head: "Fengyi said so, I don't know what he's doing." ”

He spread his hands, but Cao Cao stood up directly when he heard this.

"Ah, people are panicking in this hot weather, why don't we go and see what Fengyi is doing?"

At the moment, Cao Cao has no heart to deal with government affairs.

If there is a problem with grain and grass, I am afraid it will be difficult to conquer Xuzhou.

However, what Tao Qian did before had already aroused the anger of Cao Cao and others, and Xuzhou was bound to be conquered.

"Good!"

Xun Yu on the side also nodded.

During this time, as he began to follow Xi Zhicai, Xi Yu and the two practiced Wufowl Opera, and their bodies and bones were already much better.

However, in such a hot and dry weather, it is natural to be upset when dealing with government affairs.

It's good to go out and get some air right now.

In the early afternoon, the three of them quickly found Xi Yu who was wandering in the acres outside Changyi City.

At this time, Xi Yu was leading Dian Wei to walk between the riversides.

Due to the recent dry weather, even the river is a little shallow.

If you want to open a canal to divert water for irrigation, it is a bit laborious, but if you can bring water down from the mountain, it is also a good choice.

Thinking like this, Xi Yu already paid attention to it in his heart.

I have inspected the whole territory of Yanzhou before, but Xi Yu did not find anything like a waterwheel, and now the irrigation fields are all canals to divert water.

However, due to the severe drought and the drop in river water, the difficulty of opening canals to divert water has increased considerably.

If water from the mountains can be used, it can greatly alleviate the drought in the fields.

"What is Fengyi thinking?"

When Xi Yu was thinking about how to build a waterwheel, Cao Cao and the three had already appeared next to Xi Yu.

Seeing the other party bow his head and ponder, Cao Cao couldn't help but ask.

"I'm thinking, make a thing that diverts water from the source to solve the trouble of irrigating fertile land!"

replied to Cao Cao, about the structure of the waterwheel is actually not troublesome, he just thought about it a little, and it was already clear.

Now that Cao Cao asked, he answered casually.

Hearing that Xi Yu was really the same as what Xi Zhicai said before, Cao Cao and Xun Yu couldn't help but be a little curious.

"How do you bring water?"

"Where is the water?"

The two spoke at the same time, and the questions were different.

Xi Yu looked at the two of them: "Build utensils and lead the water of mountain streams!" ”

Watermills can also be built near the river, but this is limited to fields close to the river.

There are still some fields in Yanzhou that are a little far away from the river, and these fields naturally cannot be irrigated by river water.

However, these fields are not far from the mountains of Yanzhou, and it is no problem to divert water from mountain streams.

"Artifact, what artifact?"

Cao Cao was full of doubts, what could lead water to the fields?

It was hard for him to imagine that Xun Yu was also a little confused on the side.

Xi Yu didn't explain carefully to the two.

After the waterwheel was built, the two of them could understand it when they saw it.

"Lord, I already have a draft in my heart, I'll go back to recruit craftsmen first, this thing can't be made by me alone!"

In order to divert the water from the mountain stream, a large waterwheel had to be built.

And in this case, it is natural to have to dig a ditch down from the mountain, and this project is not troublesome.

This kind of thing of opening a canal has not been done less by the military and civilians in Yanzhou during this time.

All you need to do is recruit people.

As for the waterwheel, it naturally needs some craftsmen to help.

The previous Quyuan plow was simple, and he could do it alone, but if he made a large waterwheel, if he did it alone, he didn't know how much time it would take.

Hearing that Xi Yu was going to recruit craftsmen, Cao Cao nodded subconsciously.

"Since Fengyi has a draft, he can recruit craftsmen in my name!"

Regarding Xi Yu, Cao Cao naturally believed in it very much.

Whether it's a qu yuan plow or a three-piece suit, these things are all made of jokes.

The utensils that can lead water to the source, Cao Cao is also looking forward to it in his heart.

If such a thing can really be made, there will be no hidden dangers in the entire Yanzhou fields.

"In this way, I also have some expectations for what Fengyi will create!"

Xun Yu also laughed.

Xi Yu nodded, turned around directly, and planned to return to the city with Dian Wei.

At this time, Cao Cao seemed to suddenly think of something and hurriedly shouted at Xi Yu.

"Fengyi, I forgot to tell you something!"

"I originally planned to go to the court to show you for your merits, but our envoys were intercepted and didn't see the Son of Heaven at all!"

Cao Cao didn't expect that Li Dao and Guo Yan were so bold that they even rejected the piece they played!

When such a situation happened, he was somewhat sorry for Xi Yu.

Hearing this, Xi Yu didn't care.

No wonder, Cao Cao's recital has been playing for two months, but there is no news on it, and the emotional road is gone!

However, this matter is nothing.

"Oh, it's nothing, the lord doesn't have to take it to heart!"

Xi Yu shook his head, he didn't care about the performance of the court.

However, Cao Cao wanted to welcome the Son of Heaven in the future, but now he can't even play a piece of music, which is a trouble.

If he remembers correctly, it won't be long before there will be a gap between Li Dao and Guo Yan, and when the time comes, the two sides will be in turmoil, and it will be the time for Cao Cao to welcome the Son of Heaven.

However, if the Son of Heaven doesn't know who Cao Cao is, if he wants to meet the Son of Heaven, I'm afraid it will be a bit of a problem!

Historically, when Emperor Xian of the Han Dynasty fled to Luoyang, he naturally knew Cao Cao, and it was he who ordered Cao Cao to welcome him, and then Cao Cao could meet the Son of Heaven.

As for this, in between, how the Son of Heaven is familiar with Cao Cao, Cao Cao must have a good sense of existence.
