The eldest brother of the Li family frowned and looked at Han Nuo: "Do you remember the filtration procedure of the waterworks?" Why don't we get a simple distillation device for these villagers? ”

"Yes, I order a hundred sets in modern times, it shouldn't cost much, but it will take some time. "We can teach them to filter water first, at least they don't have to go through the trouble www.biquge.info of water for three days." ”

"Soil filtration?" The eldest brother of the Li family asked, "What kind of filtering method?" ”

"Stone and sand are placed in a certain order to make the simplest sewage treatment plant." Han Nuo said, "I can't tell you the specifics, let's follow these people to their village first and instruct the villagers to make one." ”

"Okay." The eldest brother of the Li family beckoned the other four to follow behind the villagers, and when they heard that Han Nuo had a solution to the villagers' water supply, they were all full of interest and curiosity.

Before the war, there were nobles in the paddock every year, and they saw a lot of nobles, and besides, these nobles were not unreasonable, they did not offend them, and the nobles would not do anything to them - mainly because the emperor was there, and no one dared to cause trouble under the emperor's nose - these nobles were willing to follow them, and let them follow, and it would not hinder them from working.

As a result, this group of nobles followed them into the village, and asked them to find the village chief, saying that there was a way to turn sewage into clean water! Although the villagers didn't believe it very much, they attached great importance to it, and a young man about twenty years old immediately ran to call the village chief, and Han Nuo and the others knew from others that this young man was the eldest grandson of the village chief.

The village chief soon came, and not only his whole village came. Even though they don't believe a few young people, what if they are all true? With a sense of hope, all the villagers gathered at the entrance of the village, hoping to witness the miracle happening.

"Little old man Zhang Guang has seen several nobles." The village chief is over fifty years old, but his hair and beard are already white, and his eyes are precipitated with the vicissitudes and wisdom of the years, this is a wise old man. This alone is worthy of Han Nuo and the eldest brother of the Li family to be polite to the old man.

"Village chief, don't be polite." The eldest brother of the Li family helped the old man up, and saw the distrust of the few of them in the eyes of the old man.

The old village chief really didn't trust the eldest brother of the Li family and the others, and when he heard the eldest grandson say that someone could help them solve the draft problem, the old man was still very excited, thinking that the eldest grandson had met a master. And the masters, most of them are old and have accumulated time and are highly respected, but when the old village chief came to the entrance of the village, he saw only a few young people with just grown hair, and the excitement disappeared. What does such a young man know? However, with a glimmer of hope, the old village chief still greeted a few people very politely. I don't ask them to help, I just hope that I won't offend the nobles.

Not only the eldest brother of the Li family, but also the county lord of Moyan and the others saw the old village chief's distrust, and the five of them looked at Han Nuo together. Han Nuo smiled, everything is based on the facts.

"Village Chief, please have someone bring over the largest wooden barrel." Han Nuo said to the village chief.

Although the village chief didn't believe it, he still asked people to do it. The most important thing in the village is the wooden barrel, in order to carry water and town water, it is very easy to fill water in the village, and the wooden barrel is also very large. Zhang Da, the eldest grandson of the village chief, moved the fastest, pulling a few young people as old as him to quickly bring a large wooden barrel one person high.

Han Nuo walked to the side of the barrel, leaned down and made a mark half a foot from the bottom, and said to Zhang Dadao: "Open a hole here." ”

Zhang Da looked back at his grandfather, and after seeing his grandfather nodding invisibly, Zhang Da immediately took out his tools and chiseled a small hole in the position designated by Han Nuo on the wooden barrel that was larger than the copper coin. In order to facilitate the reception of water, Han Nuo asked Zhang Da and others to put stones on the west side of the wooden barrel, and raised the wooden barrel by more than half a foot.

Han Nuo then instructed Zhang Da and his friends to put stones, small stones, gravel, coarse sand, fine sand, and soil into wooden barrels in different combinations, separated by leaves and branches in the middle of each layer, and released from the bottom of the barrel to a foot away from the mouth of the barrel.

Han Nuo circled around the wooden barrel twice, nodded with satisfaction, and instructed Zhang Da: "Pour a bucket of water that has just been brought back from the river into the wooden bucket, and take another basin and follow it under the small hole." ”

Zhang Da immediately did so, and a basin of foul river water poured over the barrel. All the people, including the eldest brother of the Li family and Yue Yunfei, were all staring intently at the exit on the wooden barrel, in addition to the sound of the wind and the chirping of birds and insects, even the dogs felt the tense atmosphere and did not dare to bark, and it was extremely quiet. Everyone's eyes were fixed on the small hole in the barrel, waiting for the water to flow out......

After about two minutes, but in the eyes of all the villagers, it was incomparably long, and finally water came out of the small hole, slowly and continuously filling half of the basin.

"Qing Shui, it's Qing Shui!" Zhang Da picked up the basin and shouted excitedly when he saw the water inside.

The villagers were in an uproar and gathered around, stretching out their heads to look into the basin. Zhang Da ran to his grandfather's side as soon as possible and handed the basin to him: "Grandpa, you see, this water is so clear, it is clearer than the water we have been in town for three days." ”

The old village chief looked down and saw that although the water in the wooden basin was not as clear as the spring water he had seen in other places, he was already able to catch up with the water in the ordinary river, and he couldn't help but cry: "Okay, good, the old man has lived for fifty-six years, and he can finally drink the clear river water!" ”

As soon as the old village chief cried like this, the rest of the villagers also cried, and there was a cry over the village, but it was not a sad cry, but a cry of hope for life. Lord Moyan and Yue Yunfei and the others looked at each other, and then they were moved, but they didn't speak, and let the villagers vent with their cries.

The eldest brother of the Li family leaned into Han Nuo's ear and whispered, "Your local method is really good, where did you see it?" ”

Han Nuo whispered back: "It looks like "Daughter of the Nile" above. ”

The eldest brother of the Li family was stunned: "What? ”

Hanno: "It's a very old Marisu comic, you haven't read it. It talks about this method of filtering sewage, which is recorded in the Mesopotamian civilization. ”

Big Brother Li: "Mesopotamian civilization? ”

Hanno: "It's the civilization of the two rivers, the civilization of the plains of Mesopotamia." The Mesopotamian Plain is located in the valley of two rivers, in the alluvial plain between the Tigris and Euphrates rivers, in present-day Iraq, where ancient Babylon, one of the four ancient civilizations, is located, is the earliest cultural development of the world's region, invented the first script for the world - cuneiform, built the first city, compiled the first law, invented the first pottery wheel for making pottery, formulated the first seven-day cycle, the first expounded the myth that God created the world in seven days and the Great Flood. ”

Brother Li: "It's as old as Huaxia?" ”

Han Nuo nodded: "Actually, Huaxia has long had a record of sewage turning into clean water, but I can't remember it clearly, but Mesopotamia's method is more clear because of the comics." ”

The eldest brother of the Li family stared at his girlfriend funny, but he heard his girlfriend say that he was addicted to the second element in high school, which led to a drop in grades and almost failed to enter college. According to her girlfriend, after reading comics like "The Sky is the Red River", she also went to study the Hittite civilization; After watching "One Piece", I want to be in the navy; After watching "Conan", I thought about applying for the Public Security University......

Han Nuo looked away embarrassedly, the black history of the second phase of the middle school has been forgotten, forget it!

After a long time, the villagers finally stopped crying, and under the leadership of the old village chief, they walked up to Han Nuo and the others, and all of them knelt on the ground, kowtowing to a few people: "Thank you for the benefactor for guiding us to get clean water." ”

Han Nuo was startled, and quickly helped the old village chief up: "Old village chief, don't be like this. ”

The old village chief was extremely grateful: "Benefactor, the method you taught us has solved the problem of our village's difficulty in drinking water for decades, and just kowtowing a few times does not show our sincerity at all." But apart from kowtowing, we have nothing to hold out and thank our benefactor. ”

Han Nuo couldn't, so he had to let the old village chief take the villagers of a village to kowtow to them. After they finished kowtowing, Han Nuo helped the old village chief up and instructed her the precautions for the simple filter: "The inside of the barrel should be cleaned regularly, and the sediment should not be allowed to settle too much in the barrel, otherwise the filtration effect will be reduced......"

The old village chief nodded again and again, and carefully wrote down the precautions that Han Nuo said, for fear that his memory would not be good, he also asked Zhang Da to memorize it with a few young people, and handed over the maintenance and cleaning of the simple filter to these young people.

The old village chief invited Han Nuo and the others to his house to rest, thinking about collecting the resources of the whole village to entertain a few people, but Han Nuo and the others refused. Several people jumped on horseback, ignored the villagers' hard work, and left the village.

"These villagers are so welcoming!" After leaving the village for some distance, Yue Yunfei exhaled with palpitations, "My coat is going to be pulled off by them." ”

The others nodded in agreement, and Lord Moyan said, "But I feel very happy, more comfortable than eating a very delicious dish." Why is that? ”

The eldest brother of the Li family replied: "Because we have helped others, giving roses to others has a lingering fragrance." It's a beautiful emotion. ”

A few ancients were thoughtful, and the eldest brother of the Li family and Han Nuo waited for them with a smile.

After a while, Yue Yunfei said, "Wei Feng has a point. ”

Geng Shi'an continued: "Just as I treated the patient, the patient was grateful to me, and my heart was also very happy and comfortable. ”

Qi Xueru said: "I like this feeling of helping people. ”

Lord Moyan clapped his hands and said, "Let's do more good deeds with us to help others!" (To be continued.) )
