Looking at their puzzled eyes, Luer smiled lightly and said:
"It's the stairs we usually see. What would happen if there were no stairs on a very high mountain?"
Looking at their still puzzled eyes, Luer was not in a hurry and just waited quietly for their answers.
"Well...ma'am, it's just a little more strenuous to walk..."
Lu'er nodded and found two pieces of paper from one side. One was folded into a ladder-like shape and the other was lying flat:
"Bring me a glass of water..."
Qing Yi didn't ask any more questions and handed it to Lu'er in confusion. Lu'er first picked up the unfolded paper, placed it at an angle, and poured water on it. All the water flowed down.
"this……"
The two of them still hadn't thought clearly, and Lu'er didn't say much, and put the paper she had just folded in place, with almost the same slope, and the same pouring of water——
"Ah... Madam, this is..."
The water did not flow out immediately. It stayed on the paper for a while before falling from both sides.
"This is the terraced fields. This paper only has one side, but the mountain is a whole..."
"Madam, isn't this possible..."
The faces of the two were very excited, and Luer nodded with satisfaction:
"I said, I will help them! But this is not enough, I have to find a way to transport water to the mountain!"
It's a pity that in modern times, she never thought that she would come to ancient times, and she had never studied these things.
If she had known that such a day would come, she would definitely...
"Madam, don't they have to carry water? Is there any other way?"
The two of them were equally puzzled. It has always been like this!
Everyone knows that you have to carry water for watering when there is a drought.
