Time passed quickly, and the day was coming to fulfill the military order.

In the early morning, Xue Yu led his friends to carry the various tools he had prepared and came out of the White Sand Castle in a vast expanse. Hundreds of military households followed closely, including Grandpas of the Hundred Houses, Grandpa Tartars, and Eunuch Lu, who were among them. They all wanted to see if they could really get out of water today?

For decades, white sand castles have suffered from water shortage. People have tried many ways, but none of them have failed!

Can this young man who is just a newcomer really create a miracle?

The team soon arrived at the destination. After a strong wind, the dunes moved their positions again. The terrain was unrecognizable. However, the plugged pole was still there, so we would not admit our mistakes.

"Take everything out and start as I told you before!"

"Yes, boss!"

With Xue Yu's order, the friends began to take out a pile of iron pipes, five feet long and thin, the adult's wrist, one end was screw pattern and the other end was turnbuckle, which could be twisted together!

One of them is an exception, one end is not a thread, but a very sharp inclined surface, and a ball of linen is stuffed inside, tied with a long rope, leading it out from the other end of the iron pipe.

These iron pipes were made of the remnants of the picked-up soldiers, the armor was melted into the molten iron, and poured into the mud sheet. A total of ten were cast and carefully polished to meet the standards required by Xue Yu!

Next, two people held the iron pipe and rushed down with a sharp incline. Hu Dachu swung the iron hammer and smashed it down with force!

After entering the ground about four feet, he took out an iron pipe, first pass it through the middle with a rope, and then twisted it with the previous one.

In order to ensure that the two are tightly fitted, some fish bladder glue was applied at the interface of the iron pipe. This was made by Xue Yu spent a lot of effort and boiled with fish skin and fish bladder. It has excellent adhesion and sealing properties. It is known as the "10,000-year prison!"

After repeated operation, all ten iron pipes were inserted into the sand and connected together, reaching four or five feet deep into the ground.

Next, Xue Yu pulled the rope, pulled up the lowest linen, and then put it on the iron pipe. After smelling the breath below, a smile appeared on his little face!

The progress is smooth, at least 70% to 80% sure.

"Sledgehammer, build a well table!"

"Okay!"

The group also brought stones, yellow mud, and the blue bricks they collected. Hu Dachui and others started to build a beautiful well platform and firmly fixed the iron pipe on it!

The well platform is relatively high, so even if there is strong wind, there is no need to worry about being buried.

At the same time, Xue Yu took out other parts and quickly assembled them...

An iron bucket over three feet long and thick at the waist of a child, looks strange!

A curved iron handle is more than three feet long and has a cloth strip wrapped around it, so that you will not be afraid of cold hands in winter.

A piston and a gate valve are made of three layers of cowhide coated with fish bladder glue. They are both soft and tough, and are exactly the same size as the diameter inside the iron barrel!

...

"What are they doing?"

"I don't know, the old man has lived to be almost seventy years old. He has never seen such a well digging. If he doesn't dig a thick sand, will the water come up on its own?"

"Are you teasing everyone?"

"Brother Xue is a calm person and can't do that kind of thing. Let's wait and see!"

The military households watched by the side, but no one could understand it. The things in front of them were beyond their scope of understanding.

Only Eunuch Lu pondered and seemed to have realized something. He looked up and down at Xue Yu, and the light flashed in his eyes, as if he had discovered a beautiful jade in his talent!

On the other side, Xue Yu assembled all the parts together, checked them carefully, and confirmed that there was no problem. Then he nodded with satisfaction!

The water veins are hidden under a thick layer of sand. If traditional excavation methods are used, it is difficult to dig a well. Even if you succeed by luck, your service life will be very limited and you will easily be reburied by the sand.

Therefore, I came up with a labor-saving, safe and reliable way, which is to drill a pressure well!

Pressure wells are very common in later rural areas. They use the principle of counterpressure to pump water deep underground, which is both labor-saving and convenient. Not to mention adults, even a child can operate it!

Xue Yu's grandmother's home is in the countryside, and there is such a pressure well in the yard. When she was a child, she often enjoyed playing with it. She also conducted serious research (those who can dismantle or install it), so she knew its structure and principles clearly!

Therefore, Xue Yu dared to issue a military order. Within seven days, a well was dug, which refers to the pressure well!

"Monkey, big black, pour water!"

"yes!"

A bucket of clear water was poured into the well and immediately flowed into the ground along the iron pipe, followed by the second and third barrels...

The pistons and valves in the pressure well are all one-way, causing the air to go upwards without going downwards. In this way, the pipe below is vacuumed, and the water is pumped up under the action of atmospheric pressure.

The problem is that these parts are handmade and the precision is far from enough. When the piston moves upwards, the air outside will leak in. When the piston moves downwards, the air may leak into the pipe below, making it difficult to evacuate the pipe!

Pour a few buckets of water first to increase the air tightness, which makes it much easier to pump up the air!

"Crack!--Crack!"

Four buckets of water were poured in succession, and it felt almost the same. Xue Yu held the handle and pressed it up one after another, while listening in his ears!

There was indeed a sound in the iron pipe, gurgling, from small to large, just like a bull drinking water!

...

"The water is out, the boss is pressing out the water!"

After half a stick of incense, with Xue Yu pressing hard a few times, a stream of water sprayed out from the outlet. Unfortunately, it was too turbid and mixed with a lot of mud and sand!

Xue Yu was not discouraged, but instead showed joy and continued to press the well hard. The fruit sprayed from behind was indeed much clearer, and the water flow became bigger and bigger. The monkey quickly took the wooden barrel and then pressed out the clean water!

The onlookers did not respond because they had poured four buckets of water before, but now they pressed the water up again, it seemed nothing was wrong?

But what happened next made them stunned!

The first bucket of water was soon full, followed by the second bucket and the third bucket... More than a dozen buckets of water were pressed in a row, but there was still no sign of stopping. It seemed that as long as someone pressed it, the water would come out continuously.

In other words, Xue Yu really dug a water well that he had never seen but could be used within seven days without spending a penny!

There is a well in the White Sand Castle!

In the future, I will never have to travel long distances and brave the severe cold to get water at the Kouye River dozens of miles away.

"There is a well, we really have a well. God is open to his eyes, wuwu!"

"This is all the credit of Brother Xue. He is the great lucky star of our White Sand Castle, haha!"

...

After a moment of silence, the military households reacted and rushed to the front. Someone kept stroking the pressure well, just like he was stroking rare treasures, laughing happily!

Some people also used their hands to collect water and drank it in big mouthfuls, crying while drinking. This happiness came too suddenly and I couldn't bear it anymore.

The children jumped and jumped, and they were all so happy!

After pressing more than a dozen buckets of water, Xue Yu's arms became a little numb. He took the opportunity to give up the position and asked everyone to take turns to press the water, and taught them how to use it and what to pay attention to!

After the carnival, people slowly calmed down and the well was drilled out. How to protect it became a big deal!

Some military households proposed to build a fortress on it, and send people to hold swords and guns to guard it day and night to avoid accidents!

This proposal was immediately agreed by most people, especially a few old military households, who took the initiative to ask for responsibility for staying behind. Judging from their excitement, they would have the intention of spending their lives by the well for the rest of their lives!

Xue Yu quickly persuaded him that it was just a pressure well, and there was no need to pay so much attention. Even if it was broken, it would be fine. Just take another shot.

At the same time, I explained to everyone the general principle of the pressure well, proving that this is not a miracle or a spell, but just an ordinary technique, and it is not too difficult to master!

The persuasion was effective. The military households gave up the idea of ​​sending people to stay, but they still dug up a few houses that were unoccupied and built a windproof bunker above the pressure well!

Looking from afar, it looks like a small fortress with a flag in it, with eight big words on it: This is a forbidden place, so don’t be close to anyone!

With water, the life of the White Sand Castle immediately changed tremendously. In the past, people had planned to use water. When their mouths were so dry, they dared to drink a few sips. After washing the water tank, they had to lean into their heads and lick the bottom of the tank!

It’s different now. Drink whenever you want!

In addition, the military households began to wash their hands and faces every day, especially some big girls and young wives, who have to take a shower every now and then, and their personal hygiene has increased sharply!

Whenever I see young people pouring foot wash water, the elderly will show a look of pain. Let’s say the previous sentence: ‘What a sin!’

Then go home depressedly, burn a bucket of hot water, wash your face, soak your feet, and unclog the blood vessels of the whole body, so as to calm down your depressed mood!

In the case of water, who doesn’t want to be cleaner!

Unfortunately, this happiness did not last long, and the military door began to feel sad again.

The cold winter is coming!
Chapter completed!
