Even the overturned carts used to draw water cannot be used because the water level is too low and the banks of the Weishui River are too high.

But compared to Longxi and Nan'an, Tianshui is already lucky because there are large tributaries in the middle reaches, and the Wei River has not stopped flowing yet. At least it can still be irrigated manually.

In Longxi and Nan'an, the Wei River has begun to dry up.

The worst situation is Nan'an County.

Because in addition to the Weishui River, Longxi also has the Taoshui River, the largest tributary in the upper reaches of the Yellow River, which can at least delay the drought.

But there is only one Weishui River in Nan'an, and the grain-producing areas are basically around the Weishui River and its tributaries.

Now that the Wei River has stopped flowing, Nan'an has been sentenced in advance to no harvest this year.

Zhuge Liang's eyes fell on the lower reaches of the Wei River, where there was a group of people installing something.

"Drill the stake deeper and make it firmer."

Feng Yong was directing the people of the engineering battalion to place wooden piles of the same size opposite each other in order, and drove them in an array from the river to the river bank.

It has entered the hottest period of time, and you can feel the sweat on your chest flowing down continuously. The clothes on your back have become wet, clinging to your body, making it sticky and uncomfortable.

The strong, shirtless man shouted slogans and kept pounding the piles into the soil.

Under the fierce sunshine, everyone's body was shiny.

"Okay, let's get ready for the next batch. Those below, please come up and take a sip of the black bean soup."

Seeing the sun getting stronger and stronger, Feng Yong shouted.

Take turns so that everyone is familiar with the process so that they can work separately later.

Seeing someone who couldn't resist the cool temptation of the water and was about to go down and roll around before coming back up, Feng Yong was furious. He bent down to pick up a stone and threw it down. The stone missed the target with a "pop" sound.

It didn't hit anyone, but hit the water in front of that person.

Feng Yong pointed at him and yelled, "How many times have I told you! Don't go into the water when your whole body is sweating!"

"My ears are already hairy and I can't hear, right? I'll have a cramp and fall into the water, and I won't know if I've been washed away! Look, what are you looking at? I'm talking about you, why don't you get out of here!"

Wenshi took advantage of the gap between people to change people and took people down to measure the height of the piles and the distance between the two piles to see if the requirements were met.

"How long will it take for it to be ready? Are you sure?"

Feng Yongzheng was watching as he directed the next group of people to move down, when he heard the Prime Minister's voice suddenly coming from behind him.

He quickly turned around and was about to salute when he saw Zhuge Liang wave his hand.

"Back to Prime Minister, when I was in Yuexi, I had someone make a water mill. There happened to be a few craftsmen in this engineering camp who had made water mills. They are familiar with this, and I think they can make it in the next three days.

"

"Don't worry, Prime Minister, I revised this waterwheel again last night, and I am sure it will not be less than 60 to 70% sure."

With such a simple principle and so many people under his control, even if he ends up with a defective product, Feng Yong is sure to change it into a quality product.

After the Northern Expedition ended, Zhuge Liang should have arranged for his people to stay in Longyou, and then take them back, either to stay in Hanzhong or back to Jincheng, and to calculate the contributions of everyone in the Northern Expedition so that he could be rewarded based on their merits.

Unexpectedly, because of the drought, he stayed in Longyou for a long time.

Feng Yong was naturally not idle either.

The water level of the Wei River is too low, and the valleys in many places are too deep. Ordinary waterwheels cannot pump water, so we can only improve it.

He first drew a vision of a tall waterwheel based on illustrations from later generations, and then found a few old craftsmen in the engineering camp to explain his vision in person.

Then I made a simple test product and found that it was indeed feasible, so we officially started the project.

Zhuge Liang received the drawings of the high-tube waterwheel from Feng Yong and came to check the progress every day.

It basically starts with these two questions: "How long will it take to get it done? Are you sure?"

It can be seen that the drought in Longyou really made him worried.

Compared to Longyou who was wailing all over the place, Jincheng fell into huge ecstasy.

The victory of the Northern Expedition and the news that Longyou had been decided reached back to Jincheng. Even the emperor couldn't help but order to cancel the curfew for three days and rejoice with the people.

At the same time, the personnel who had long been prepared to reward the Northern Expeditionary Army could finally start their journey.

Some people are happy and some are sad.

Since the news of the victory of the Northern Expedition came, especially the emperor relaxed the curfew, and because the prime minister set out from the north gate of Jincheng, even the northern wall of Jincheng has been relaxed in the past few days.

The original intention of the government was to allow officials and people to climb up the city wall, look far to the north, and feel the power of the Northern Expedition army.

Unexpectedly, there was actually a desperate guy who took this opportunity to run to the city wall, crying and laughing, and yelling crazily, "It's gone up, it's gone up."

"What I regret most in this life is going to that place where evil spirits were born..."

Some words that are incomprehensible.

Finally he jumped and jumped off the city wall.

Moreover, there were not just one or two such people, but several in a day, just like dumplings, forcing the government to block the city wall in advance.

Do you think these people are sick?
