As soon as they heard that Yu Hao was rewarded, the people didn't care about anything else, they threw off their arms and dug up.

Three hundred people took turns to go into battle, and the speed of digging was very fast, and an hour passed to dig a large pit more than ten meters deep and seven or eight meters wide.

The soil was wet, but there was no sign of water.

"It's been so long, and I haven't dug up the water yet, Master Pony, I'm afraid your method won't work!" Hu Xianwu said.

"Lord Adjutant, don't you see that the soil is already wet, which means that we are almost successful!" Lu Xiaoming hurriedly said.

Although he didn't know the bottom in his heart, he still chose to believe Yu Hao.

"This used to be a lake, and the soil was soaked in water, and the soil was buried so deep that it wasn't completely dry, so there was no water source, and we were going to be able to squeeze water out of the dirt?" Hu Xianwu said angrily.

At this time, the sun hung in the sky like a big fireball, and there was no place to hide.

The group was completely exposed to the sun, and they were all roasted and sweating profusely, and they had to be roasted if they continued like this.

As time passed minute by minute, Hu Xianwu was already a little unbearable.

He wanted to suggest that everyone go back first and come out to find water another day, but seeing that Zhou Ren was still insisting, he naturally didn't want to say anything.

It can be seen from Zhou Ren's dark skin that he doesn't bask in the sun on weekdays, and at this time, except for some heat, it's nothing.

But he is not concerned about the question of whether it is hot or not, he now only wants to dig up water as soon as possible so as to solve the drinking water problem of the people of Guangyi Mansion.

At this time, the people had already dug down more than 20 meters, but there was still no water, and under the scorching sun, many people had mild symptoms of heat stroke.

Even Yu Hao frowned slightly, the method of using mugwort leaves to find water sources Yu Hao saw in the book in his previous life, shouldn't it be ineffective?

Just when Yu Hao was doubting himself, an excited voice suddenly came from the deep pit: "Out of the water, really out of the water!" ”

Everyone was overjoyed and hurriedly looked towards the bottom of the pit.

I saw a stream of water gushing out from the ground, and the water column instantly soared to three or four meters, and in a blink of an eye, the water in the pit did not pass the instep of the people's feet.

"Enlarge the water outlet, and the others will come up immediately!" Yu Hao hurriedly shouted into the pit.

Several people received the order, and a few hoes went down, and the water outlet was instantly expanded, and the groundwater suddenly gushed out.

The people did not dare to slack off, and hurriedly climbed up from the pit along the rope, and everyone's face was filled with the joy of victory.

As the water level got higher and higher, it was not until less than two-thirds of the way through the crater that it gradually subsided.

Looking at the water in the deep pit, Hu Xianwu's eyes widened and he muttered: "It's out of the water, it's really out of the water, it's God!" ”

Hearing Hu Xianwu's chatter, Lu Xiaoming's eyes suddenly flashed with a look of pride and said, "What's the matter, my eldest brother is amazing, right?" ”

"Awesome, awesome!" Hu Xianwu nodded like pounding garlic.

"Yu Hao, how do you know that this place must be able to dig up water?" Shi Meng asked suspiciously.

Shi Meng obviously asked the question in everyone's hearts, and for a while, everyone's eyes were focused on Yu Hao.

Yu Hao smiled slightly, took out a mugwort leaf from his arms, and said, "That's because of this." ”

"One of the properties of mugwort leaves is that the smoke produced by burning does not float upwards into the air, but goes down the ground, and when it encounters a water source, it will evaporate and rise with the water."

"So after we light the mugwort leaves, as long as we go within a radius of five miles to find where there is smoke coming out, then there must be a water source underground."

As soon as Yu Hao explained this, everyone understood, they didn't expect Ai Ye to have such a use, and they all rushed to Yu Hao to look at him with admiration, especially Lu Xiaoming.

Obviously, they are all young second-generation officials, why Yu Hao understands everything, but he is like a second fool.

Feeling the adoring eyes of everyone, Yu Hao smiled slightly.

This method of finding water was a necessary skill for marching and fighting in ancient times in previous lives, and it can be said that it was widely known, but it seems to be the first time I have heard of it in this world.

At this moment, Zhou Ren suddenly knelt in front of Yu Hao with a "plop", and kowtowed to Yu Hao again and again: "Thank you for finding the water source and saving the lives of hundreds of thousands of people in my Guangyi Mansion!" ”

Yu Hao was taken aback, and hurriedly helped Zhou Ren up and said: "Lord Zhou, what are you doing, this is what I should do, I have already taught you the method, and the rest is up to you." ”

Zhou Ren nodded, and hurriedly said: "Don't worry, you know what to do, and you won't let you down." ”

At this time, Zhou Ren was already in tears, but not sad, but excited.

After learning this method, he can send people to find water sources all over Guangyi Province, so that the people of Guangyi Province do not have to worry about drinking water.

Thinking of this, Zhou Ren hurriedly looked at Hu Xianwu and ordered: "Xianwu, you immediately spread this method to the counties, let them immediately start looking for water sources, and if anyone is slack, they will not be forgiven, and notify the surrounding people to come and get water quickly!" ”

Under the sun's baking, a large amount of water evaporates every once in a while, and it can't be wasted.

Hu Xianwu was completely impressed by Yu Hao at this time, and nodded hurriedly, not daring to have the slightest opinion.

At this moment, a dart master hurriedly ran over and arched his hand: "Report to the sir, we found an injured old man when we were on guard, he recognized us as the dart master of Haoyue Manor, let us bring him to meet you." ”

"Wounded old man? Want to see me? Yu Hao was stunned for a moment and said, "Bring him over!" ”

The dart master got Yu Hao's answer, and waved his hand to the four dart masters not far away, and the four of them hurriedly carried a person wrapped in a black cloak and walked over.

The man seemed to be badly wounded, and the dart masters simply put him on the ground.

"Sir, this is the old man who wants to see you, but he has fainted now."

Yu Hao frowned, squatted next to the old man, took off the mask that covered his face, and suddenly revealed a familiar face.

"Father-in-law?" Yu Hao's eyes widened, isn't this the old eunuch Feng Yulou next to the emperor?

I hadn't seen Feng Yulou in the palace for a long time before, Yu Hao thought that he had returned to his hometown, how could he suddenly appear here.

"Could this person be the chief manager of the emperor's side, Feng Yulou?" Zhou Ren saw that Yu Hao called this person "father-in-law", and he also thought of something, and hurriedly asked.

Yu Hao nodded, and hurriedly began to check Feng Yulou's injuries, only to see that Feng Yulou had three arrow wounds on his back, the wounds had festered, and Feng Yulou also had a high fever due to wound infection.

The most fatal was a knife wound of tens of centimeters in the abdomen, and blood was still gushing out at this time.

And Feng Yulou just bandaged it with the clothes on his body, and in such weather, he was already seriously infected, and even a little stinky.

Seeing this scene, a flash of regret flashed in Zhou Ren's eyes: "If you are injured like this, I'm afraid you can't save it." ”
