Transformed into an extremely evil grandmother and fled to escape famine with her children and grand

Han Shunde organized the men to dig half a meter along the hole, and the width expanded, turning it into a tunnel.

After walking along the tunnel for less than 100 meters, a doorway appeared. It was obviously narrower, but it was nearly one meter lower.

So, a cart can still pass through, and it gets cooler as you go down.

After passing through this narrow doorway and walking less than 20 meters forward, the road suddenly became open.

Li Lanzhen found that the mountain walls on both sides were very damp, but, very strangely, she did not find any plants. She stretched out her hand, touched the damp stone walls on both sides, and grabbed a handful of wet, white sand-like substance in her hand.

She put it under her nose and smelled it, and it had a strong smell of salt and alkali. She suddenly had a very bad feeling in her heart. She hoped that it was not what she thought.

An hour later, people from the three villages arrived at the bank of the underground river.

This underground river is relatively wide and the water is not deep, and the banks on both sides are quite wide.

People from Hanjia Village gathered on this side of the river bank, looking at the clear, gurgling river water. Everyone cheered happily, and the children jumped into the river.

The adults couldn't wait to bend down and gulp down the water.

But then there were coughing sounds and vomiting sounds of "Pah pah pah".

"Damn, why is this water so bitter and astringent?"

"Mom, my throat hurts. The water is so salty!"

Han Mingjiang resisted the urge to drink and led the big blue mule and the black donkey to the river, thinking of letting them drink first. Unexpectedly, the big blue mule bent down, took a sip, then raised its head and sprayed water all over Han Mingjiang's face.

Then the big blue mule raised its head and neighed.

For a moment, the underground river was filled with the sounds of cursing, coughing, children sobbing, and livestock roaring.

Li Lanzhen closed her eyes and said to herself: It is just as I guessed!

This underground river should contain saline and alkali. No wonder there is no grass growing in this stone forest. Once you enter the underground river, although the climate is humid, there are no plants, not even a single saline-alkali Artemisia selengensis can be seen.

People had been looking forward to it, but now they were extremely disappointed. They lost all their energy and sat down on the ground, clapping their hands and crying.

Li Lanzhen felt bad watching them like this, but everyone had to think about what to do. The first thing to solve was how to get out. Should they just follow the underground river?

At this moment, the old village chief called her again, "Lanzhen, bring the map over. Let's see if we are going in the right direction by following the river."

Li Lanzhen took out the map from her arms and handed it to Han Mingjiang.

This time, she did not follow them. She did not want to look at the direction. They just made the decision. Now, she had to think about how to make use of this underground river?

Seeing that the river water was not turbid, she kept thinking about how to make the water drinkable, or at least how to reduce the salinity to a less high level.

The first thing she thought of was filtration, but then she realized that was not the right thing to do, as filtration is only suitable for more turbid water.

The water of this river is clear, but it contains a high salinity. Filtering is not an effective method, so the only option is distillation. However, without advanced distillation equipment, the primitive method of distillation is slow.

The amount of water extracted is relatively small. I don't know how long I can stay here. And can I get out by following the underground river? Or do I have to go back the same way and pass through the stone forest.

Li Lanzhen thought as she walked, picking up stones from time to time. After arriving at the stone forest, when she saw stones with beautiful shapes, unique features, or beautiful colors, she quietly sent them into the space.

She remembered that there was a merchant who needed the stone, but she forgot which one. Anyway, she hung it there and whoever wanted it could take it.

There are many stones on both sides of the underground river. Without exception, no matter what color or shape the stones are, they are covered with a layer of alkali like white frost.

She picked up a palm-sized stone covered with a layer of furry frost and alkali flowers. She stuck out her tongue, licked it gently, and immediately felt that the salty taste was stronger than the alkaline taste.

Li Lanzhen's eyes lit up. This showed that the underground river contained a relatively high amount of salt. Was it possible to distill out pure water while extracting the salt?

When we were in the village, there was not much table salt. We bought the inferior quality salt. The large grains of salt were yellow in color, tasted a bit bitter, and there was not much of it.

There were so many prey caught in the mountains, but no one dared to extravagantly pickle them with salt, and no one dared to extravagantly pickle the wild vegetables with salt to take away.

It would be great if we could use this river water to extract salt.

Thinking of this, she rushed over to Wang Hui and called on her daughter-in-law and brother's wife to start the experiment.

Xue Nizi, Tonghua and Li Sanya quickly set up the pot according to her instructions and began to draw water from the river and pour it into the pot.

Li Lanzhen ran to her family's large blue mule cart, rummaged around, and took out a bundle of firewood that she had collected from the firewood room of the Ankang Prefecture government office.

"Nizi, light a fire, fill the big iron pot with water from the river, light a fire underneath, and boil the water."

Xue Nizi asked in confusion, "Mom, why are you wasting firewood? This water is bitter and astringent, and can't be drunk. Even if you want to make paste, the paste you make can't be drunk either."

Xue Nizi's mother, Mrs. Wu, came over and patted her on the shoulder. "Your mother-in-law's instructions will definitely be very useful. Just do as she says."

Li Lanzhen looked at the in-laws with admiration and sighed in her heart that the in-laws that the original old lady had met were all very good families and could become relatives and friends for long-term cooperation.

Goudan, Han Yinan and the others were excited and proud at the beginning, thinking that they had found an underground river. But when they arrived, they found that the water was bitter and astringent and could not be drunk. They were angry and disappointed, and they all looked depressed.

Soon, the children's nature prompted them to run up and down the river bank, looking for fun.

The men gathered around the old village chief to look at the map and discuss which way to go next.

Li Lanzhen and a few relatives started their own experiment. She tilted the large iron pot slightly, covered it with a wooden lid, and extended the lid slightly in the tilted direction, with a wooden barrel underneath.

Then he told them to light a fire.

No one cared. It was just a matter of a few bundles of firewood. Just burn it if Li Lanzhen asked them to.

As a result, when the water turned on, the dripping sound attracted their attention.

It turned out that there were drops of water, dripping from the tilted side of the pot lid into the wooden barrel below.

Li Lanzhen began to catch the water droplets in a bowl.

After collecting the water from the bottom of the bowl, he slowly took a sip of it against his lips, smiling happily.

Then he handed it to Xue Ni, who was sitting on the ground and burning the fire unhappily, and said, "Nizi, come and try this water and see if it's drinkable."

Xue Nizi grumbled unhappily, "Isn't it just saline water? It's just boiled. Even if it's boiled, it's still saline water."

Unexpectedly, she took a small sip, then took a big gulp, then raised her head and poured it all into her mouth.

With sparkling eyes and smacking his lips, he shouted at Li Lanzhen, "Mom, you are amazing! How can you turn salty and bitter water into drinkable water by boiling it?"
