Don't worry, mother, I've brought the golden finger to change your fate

Since the last creative market was a great success, Lin Ruowei and Gu Yan's reputation has become more and more famous in the village. The villagers' lives are getting better and better, but this morning, a hurried knock on the door once again broke the silence.

"What happened again?" Lin Ruowei had just got up and was about to have breakfast. When she heard a knock on the door, she hurried out of the room.

Gu Yan was already in the yard to greet the guests and saw several villagers standing at the door with sad faces, one of them was holding a crying child.

"What happened?" Gu Yan asked.

"Ms. Lin, Mr. Gu, the well has dried up!" said the village chief anxiously.

"The well is dry? That's the main source of water for the villagers!" Lin Ruowei's heart sank when she heard this.

"Yes, we discovered this morning that there was no water in the well, and no one knew what to do." The village chief frowned.

"This is a big deal, we must solve it immediately." Gu Yan said decisively.

Lin Ruowei and Gu Yan followed the village chief to the well, only to see the villagers gathered at the well mouth, all with sad faces. Lin Ruowei looked into the well and found that the bottom of the well was dry, with only a few pieces of wet soil.

"This is not a good situation." Lin Ruowei said, "We have to find a new water source."

"Everyone should split up and the strong men should dig temporary wells first, and the others should look for new water sources." Gu Yan suggested.

The villagers responded and took action separately. Lin Ruowei and Gu Yan led several villagers to search for water in the woods outside the village.

After walking for a while, Lin Ruowei suddenly stopped and asked: "Did you hear the sound of water flowing?"

"What sound?" Gu Yan listened carefully and indeed heard a faint sound of flowing water.

"Follow me!" Lin Ruowei led everyone to follow the sound. Soon, they found a clear stream in a dense forest.

"Great, we found a water source!" Gu Yan said happily.

"Everyone, go back and report the news so that the villagers can come and get water." Lin Ruowei ordered.

After hearing the news, the villagers rushed to get water, and everyone finally breathed a sigh of relief. Lin Ruowei and Gu Yan decided to build a temporary water station next to the stream to facilitate the villagers to get water.

A few days later, the temporary water station was built and the villagers' lives gradually returned to normal. In order to ensure that the wells would not dry up again in the future, Lin Ruowei and Gu Yan invited a scholar who knew about water conservancy to help survey the water source in the village and develop a long-term water conservancy plan.

One night, Lin Ruowei and Gu Yan were chatting in the yard.

"It was a close call today." Lin Ruowei sighed.

"Yes, fortunately we found a new water source in time, otherwise the consequences would be disastrous." Gu Yan nodded.

Just as the two were chatting excitedly, the village chief ran over in a hurry and said breathlessly: "Ms. Lin, Mr. Gu, there is also a problem with the newly dug temporary well!"

Lin Ruowei and Gu Yan looked at each other and immediately followed the village chief to the scene. The temporary well was crowded with villagers, who were talking and looking anxious.

"What's going on?" Lin Ruowei asked.

"The well water suddenly became turbid and gave off a strange smell," a villager replied.

Gu Yan squatted down, scooped up the well water and smelled it, frowning: "This water can't be drunk, we must find the reason as soon as possible."

Lin Ruowei and Gu Yan set out again, looking for the source along the stream, hoping to find the root of the problem. They took several villagers with them, crossed mountains and ridges, and finally found a hidden cave in front of a stone wall, where the water was flowing out.

"There must be something wrong here." Lin Ruowei said.

They entered the cave and found some strange mineral deposits in the cave. The water became turbid and poisonous after passing through these minerals. Gu Yan took some samples with the tools he carried with him and brought them back to the village for scholars to analyze.

A few days later, the scholars brought good news: "These minerals are indeed toxic, but we can divert the water flow to avoid these minerals and ensure the water quality is clean."

The villagers were relieved when they heard the news and immediately started the diversion project. After hard work, the water quality of the stream became clear again and the villagers could get water with peace of mind again.

In order to prevent similar situations from happening again, Lin Ruowei and Gu Yan decided to establish a simple water source monitoring system in the village. Although there were no modern scientific and technological means in the Ming and Qing dynasties, the ancients had their own wisdom:

Regular inspection: The village selects several reliable villagers to take turns to inspect the water quality of the well and stream every day, observing the color, smell and transparency of the water. If any abnormality is found, it will be reported immediately.

Water filtration: Set up a simple filtration device near the temporary water intake station, using natural materials such as sand, charcoal and wood ash to initially filter the water source to ensure clean water quality.

Water source protection: set up fences to prevent animals from approaching water sources and polluting the water quality. At the same time, organize villagers to regularly clean the surrounding environment to prevent garbage and harmful substances from entering the water source.

Record log: Prepare a record log to record in detail the daily inspections, weather changes and water quality changes in order to analyze and summarize experience.

At night, Lin Ruowei and Gu Yan were in the yard. Lin Ruowei said with emotion: "This time it was really thrilling, but we finally solved the problem."
