Chapter 1138 The City on which the Sun Never Sets 8

  The groundwater is easy to find.

  There are two signs there, and the cross-section looks like a huge stone with the Chinese character "人".

  Fu Anan traded at the entrance of the cave yesterday, so he didn't go in to have a look at it. Today she paid the toll for going in, and went in with the bucket she bought at the same time as she bought water yesterday. By the way, it costs more to buy buckets than to buy water!

  Bend down and enter from the passage under the character "人", the passage inside is very narrow. At most two people can pass through here side by side, and the more you go inside, the more you can feel the humidity inside.

   Arriving soon.

  Compared to the narrow mouth on the outside, the inside is very wide, and there is a small spring in the middle. The groundwater gushes up continuously from below, forming a small pool of about four meters.

  The surrounding area can accommodate six or seven people to fetch water at the same time. When Fu Anan arrived, there were already people around, and her appearance did not attract the attention of others at all.

Fu Anan also joined them with a bucket in hand. She squatted by the pool, pressing the bucket down with her hands, seemingly filling it into the bucket, but actually opened up the space, and the water in the pool was pouring in continuously. .

  The action was too fast, the speed of the groundwater upwelling could not keep up with the speed of the Fuan installation, and the water level began to drop. Fortunately, it was very dark inside, and Fu Anan found out before anyone else noticed. She quickly slowed down her hand, but still collected a considerable amount of water inside.

   It took a long time, and finally attracted the attention of the people receiving the water behind. Seeing Fu An'an's motionless appearance, the guard yelled, "Hey! That woman, what are you doing?"

   "I didn't do anything."

   Fu Anan stood up quickly after hearing the words, and said with an innocent expression.

   "What are you doing with your hands in the water all the time? It takes so long to pump a bucket of water?"

  The man glanced at the wooden barrel at her feet with a look of vigilance, "Do you have anything on you?"

   There is a reason why he is so vigilant. A few days ago, a camel team passing by told about another Gobi oasis, where the water source was poisoned by a person. The people in the Gobi were either poisoned to death or thirsty to death, and they couldn't allow them to be nervous.

"No!"

  Fu An'an heard the words and quickly raised his hands to show his innocence. The water keeper didn't believe it, so he scooped up another ladle for her to drink. After waiting for a long time to see that she was fine, he let her go.

  Fu Anan looked at the space, there must be several tons of water, definitely not enough for a bath, but it is definitely more than enough for two or three people to drink.

   Next, there are things like salt and medicine. In the Gobi where materials are extremely scarce, these things are also called white gold and green gold. Even if you have money, it is very difficult to get it. There are almost no sales outside. There are camel caravans, but all of them are reserved.

   In the end, Fu Anan entrusted his relationship with the hotel owner to make a reservation. There was also a high commission, but luckily it was delivered together with the fruit.

   Black hearts have another way.

  Fu Anan really wanted to **** her again, but was reluctant to **** her.

  After solving all the material problems, she only cares about two things now:

  First, make a simple device for measuring time. She really felt that the days were much longer than the nights, so she wanted to get something to test.

  Hourglass, or water drop method.

   To be exact, she started trying both.

   There is no way to get a fine timer, so she spent a lot of time making two devices that can drop sand and drip water at a constant speed.

  Measure the day at the same time, and measure the night at the same time.

  Through the number of falling sand and dripping water during the day and the number of falling sand and dripping water at night, the time ratio between day and night can be calculated, so as to calculate the length of day and night.
