The richest man was provoked by Chi Wanwan and was very angry.

Chi Wanwan was in a happy mood, returned to the yamen, and in the eyes of everyone who didn't know why, he was fiddling with strange tools outside, and behaved strangely.

"Little system, is the rain date confirmed?" Chi Wanwan consciously asked the system.

It was also told by the system that she could calculate whether it had rained in the near future based on latitude and longitude, as well as the direction of the wind, the altitude of the local area, etc.

It just so happened that the richest man said that, and Chi Wanwan followed his words to provoke his opposition.

It's just that at that time, the system only said that there was rain recently, and it was not sure what day it was, so it had to be calculated carefully.

"Host, three days later, it's raining at noon." After some precise calculations, the system gives an accurate answer.

"Little system, you're sure, you can't fool me." Chi Wanwan put away his tools neatly.

"Don't worry, I won't pit you at a critical moment."

The more Chi Wanwan listened to this, the more wrong it became, and she smacked it, feeling that the small system was quite bad.

Back at the Yamen, Chi Wanwan directly asked people to post a notice: "At noon after three days, it will definitely rain." ”

Everyone talked about it, and there was no shortage of those officials behind their backs who laughed at Chi Wanwan's swollen face and became fat.

"Are you sure?" Although Xiao Junmo believed in Chi Wanwan, he was inevitably a little worried.

"Wait, prince." Chi Wanwan smiled confidently, although the small system was a little damaged, but there was nothing to say about reliability.

Three days later, in the afternoon, the sun was shining, and the land was shaky with the sun.

Everyone looked at the sun overhead, and went home in disappointment, and sure enough, playing with the nobles was ridiculous.

As a result, as soon as they turned around, a few thunderous thunders rang out, and the dark clouds quickly approached, and all of a sudden, the sky gave Chenchen, and the raindrops the size of beans fell with a bang.

The common people cheered, and took pots and pans out to receive water, and the richest man was also refreshing, and immediately asked people to take a thousand taels of silver, and others saw it and followed.

"Lord Wang, let's get started." When the problem of the silver ticket was solved, Chi Wanwan was happy in her heart, and put the topographic map in front of Xiao Junmo, outlining three places.

"This is the place I have been exploring in the past few days, the grass and trees are vigorous, the prince might as well start from these three places."

"Okay." After this incident, Xiao Junmo was even more convinced of Chi Wanwan, not to mention that he had also checked it out in person.

Xiao Junmo directly issued a notice, and after the rain stopped, he began to excavate.

The rain rained for two hours, and although it was not early, the people were still full of energy, until noon on the next day, when the entourage came to report the surprise.

"Lord, princess, the water is out, and the ditch at the foot of the mountain in the southwest is out of the water."

The joy of the attendant jumped on his face, and he carried a bowl of cloudy water from the ditch in his hand with a broken bowl.

"The water is too muddy to be quoted."

The water coming out of the ground, with sediment, Chi Wanwan sketched out a simple device for filtering water in his mind, and soon, handed a rough and simple picture to Xiao Junmo.

"Lord Wang, let someone prepare a few such filter barrels." Each layer of the barrel is clearly marked.

"Okay, thank you for your hard work."

A few hours later, the entourage reported that water had come out of two other places, and the filter barrel had been used.

"Look, this is the water filtered out of the filter bucket designed by the princess, it is cool and clean, and the filter bucket has been distributed everywhere."

It's still the same broken bowl, but this time the entourage brought crystal clear water.

Xiao Junmo took the bowl, put it directly to his mouth, and drank the water: "It's really clean, thanks to you." ”

"However, although the ditch is out of the water, the flow of the underground river is unstable, after all, it is not a long-term solution, and a canal still has to be built." Xiao Junmo had a smile on the corner of his mouth.

"The prince might as well take advantage of the previous riverbed, where the sand is soft and the formed channel will save a lot of work."

"However, the water source needs to dig small channels from other places, and the flow of water is introduced into the canal one by one, and the small amount adds up."

"In this way, the flow of water in the canal is guaranteed without over-depleting the flow of water elsewhere."

Chi Wanwan has studied Xiao Junmo's plan, which is similar to the modern south-to-north water diversion.

It's just that for such a big project, it is better to use small rivers to make up for the water flow replenishment.

"According to you, the money saved can be used to repair the river embankment and prevent the rainy season from flooding the crops."

Xiao Junmo expanded along Chi Wanwan's train of thought, even if he was exhausted, his head was extremely active.

"Wanwan, however, once the canal starts, I'm afraid I won't be able to go back before Chongyang, and this year, I can't accompany the prime minister for the holiday."

Xiao Junmo owes a little, so that Chi Wanwan loses the opportunity to accompany his family, but he is also glad that she is by his side during the festival.

"It's not just this once." Chi Wanwan didn't care, I believe that the prime minister's father will also understand.

The two of them studied the topographic map together and discussed the path of digging a small river, when a loud noise came from outside the door.

"Is there another trouble?" Chi Wanwan looked at Xiao Junmo suspiciously.

"Check it out." Xiao Junmo pushed the wheelchair, and as soon as he arrived outside the door, the two of them were greeted by the bowing of everyone.

"Thank you, Lord Wang, for not giving up on us."

"Thank you, princess, filter clean water for us, this is the pheasant I hunted from the mountains in my free time in the afternoon, it is very nutritious, give it to the princess, and I hope the princess will not dislike it."

The middle-aged man who took the lead in making trouble that day was holding a pheasant in his hand, and said in a weak tone that this gift was too cheap, and he was a little embarrassed.

"Really? Thank you, it's a rare delicacy. How could Chi Wanwan not know what he thought, so she generously took the pheasant and held it in her arms, without any disgust.

"Princess, this is the wild mountain mushroom we picked in the afternoon, and it tastes good to boil it out and make it dipping in water."

A woman glanced at the peasant woman behind her, who had apparently picked it together, and the mushrooms in it were still covered with undried soil.

The woman's eyes were full of anticipation, and the sincere emotion touched Chi Wanwan deeply.

"Thank you, pay attention to safety when entering the mountain in the future, especially in this weather, snakes will appear more frequently." Chi Wanwan still took the basket.

Everyone didn't expect that Chi Wanwan would be worried about their safety, and they were moved in their hearts, and their favorability towards Chi Wanwan rose.

"Congratulations to the host, the favorability has reached the standard, the permission has been obtained, the system mall has been opened, and the initial points have been obtained by one hundred, and the host can pick and choose what he needs in it."

The soft and cute voice of the small system sounded.

The surprise came too quickly, Chi Wanwan couldn't control the smile on her face, it was extremely bright, her happy mood infected everyone, and the atmosphere was extremely relaxed for a while.
