Groundwater is easy to find.
There are two huge stones with the symbol of "人" in cross section when put together.
Fu Anan had already made the transaction at the entrance of the cave yesterday, without even going in to take a look. Today, she paid the toll and went in with the bucket she bought with the water yesterday. By the way, buying a bucket is more expensive than buying water!
Enter from the passage below the Chinese character "人". The passage is very narrow. At most two people can pass through it side by side. The further you go inside, the more you can feel the dampness inside.
It will be here soon.
Compared to the narrow entrance outside, the inside is very wide, with a small spring in the middle. Groundwater continuously gushes up from below, forming a small pool of about four meters.
The area around could accommodate six or seven people fetching water at the same time. When Fu Anan arrived, there were already people around, and her appearance did not attract any attention from others.
Fu Anan joined them carrying a bucket. She squatted beside the pool and pressed the wooden bucket down with her hands. It seemed that she was filling the bucket with water, but in fact she was making room for it. The water in the pool was just pouring into it continuously.
The movement was too fast, and the speed of the groundwater rising could not keep up with Fu An's installation speed, and the water level began to drop. Fortunately, it was dark inside, and Fu An'an discovered it before others noticed it. She hurriedly slowed down her hands, but still collected a considerable amount of water in the pool.
It took quite a while, and finally attracted the attention of the people behind him who were being watered. Seeing Fu An'an motionless, the guard shouted, "Hey! That woman, what are you doing?"
“I didn’t do anything.”
Upon hearing this, Fu Anan quickly stood up and said with an innocent expression.
"Why do you keep your hands in the water? Does it take so long to fetch a bucket of water?"
The man glanced at the barrel at her feet with a wary look on his face, "Do you have anything with you?"
There was a reason why he was so alert. A few days ago, a camel caravan passing by told them that someone had poisoned the water source in another Gobi oasis. The people in that Gobi were either poisoned or died of thirst, so they had no choice but to be nervous.
"No!"
Fu Anan looked at the space. There were several tons of water. It was definitely not enough for taking a bath, but it was definitely more than enough for two or three people to drink.
Then there are things like salt and medicine. In the Gobi Desert where supplies are extremely scarce, these things are called white gold and green gold. Even if you have money, it is very difficult to get them. There is almost no gold for sale outside. Camel caravans may have some, but they are all reserved.
Fu Anan finally made a reservation through the accommodation owner through his connections, which also involved a high commission, but fortunately the room was delivered together with the fruit.
The evil-hearted ones have connections.
Fu Anan really wanted to have sex with her, but was reluctant to do so.
After solving all the material problems, she now only cares about two things:
First, make a simple time measuring device. She really felt that the day was much longer than the night, so she wanted to make something to measure it.
Hourglass, or water drop timing method.
To be accurate, she started trying both.
Since she couldn't make a sophisticated timer, she spent a lot of effort making two devices that could drop sand and water at a constant speed.
Measure the day at the same time, and then measure the night at the same time.
By using the amount of falling sand and dripping water during the day and the amount of falling sand and dripping water at night, we can calculate the time ratio between day and night, and thus calculate how long the day and night are.
