Chapter 3528

"Of course not." Yan Qingyi said, "After the mud is put into the sack, the mud inside will be washed away by the river water. Only stones can be used. The stones are heavy, and the river water will not wash them away."

The sack is perforated. Once the mud is put into the sack and thrown into the water, the mud inside will be washed away by the water.

But the stone is different, the weight of the stone is there, and the river will not wash it away.

"But if this happens, a lot of time will be wasted." He Gongdao.

"Even if you waste a lot of time, you have to do it." Yan Qingyi said.

"That's it, I will start quarrying and transporting it tomorrow." After He Xian finished speaking, the river worker didn't dare to say any more.

He Xian looked at Yan Qingyi and asked curiously, "Qing Yi, how will those stones be taken out when they are thrown into the river?"

Yan Qingyi explained: "Well, you don't need to take out the stones. After the stones tighten the channel, the water's momentum will increase. They won't wash away the stones, but only the sand in the river."

"So it is." He Xian nodded.

The river workers have been dealing with river water all the year round, and they have never heard of the so-called swirl-water flushing method. Now hearing Yan Qingyi say that, they instantly feel a sense of ignorance.

Yan Qingyi left the place and walked towards the middle of the river.

He Xian and He Gong followed behind her.

After walking for about half a column of incense, Yan Qingyi stopped by the river.

She pointed to the river and said to the river worker: "Let's start here first, this is the middle reaches of the river, and a lot of river sand will accumulate here. As long as the river here is tightened, the river sand will naturally be washed away. "

"Okay, Lord Shangqing." He Gong cupped his hands.

"Let's go, go back, it's getting dark." After He Xian finished speaking, he turned and walked towards the camp.

When they got back to camp, the tent was already set up, and now it was dark.

After the river workers prepared the food, they sent it to the camp of Yan Qingyi and He Xian.

Although those are rough men, their cooking skills are quite good, and they taste delicious.

After eating, Yan Qingyi went outside the camp.

Tonight is full of moon and stars, and tomorrow will definitely be a sunny day.

I really hope that the next period of time will be sunny, so that the ground can dry faster, otherwise, the ground will be too muddy, and it will be very inconvenient for the river workers to work.

Zhang Jinzhang walked over to Yan Qingyi, cupped his hands and said, "Lord Shangqing, our Prime Minister has a request."

"Oh, I see." Yan Qingyi followed Zhang Jinzhang and went outside He Xian's tent, but Zhang Jinzhang didn't go in.

After Yan Qingyi entered the tent, he saw He Xianzheng sitting by the bamboo bed reading a book, and when Yan Qingyi came in, he put the book aside.

Yan Qingyi walked up to him, cupped her hands and said, "Master Prime Minister, do you have anything to do with the next official?"

"Can't I come to you if I have nothing to do?" He Xian asked rhetorically.

"Ah?" Yan Qingyi looked puzzled.

"I asked you something earlier, and you haven't answered me yet."

"What's the matter?" Yan Qingyi frowned.

"Didn't the truth tell you to go home to visit relatives when you came? How about it, do you want to go back?"

No, is He Xian free?

Did you call her here specifically to ask her about this?

"Cough, okay, but the Xiaguan's family is relatively poor, I'm afraid that the Prime Minister's presence will make you dislike the Prime Minister."

"No problem, I also want to see what kind of parents can educate talents like you."
