Putting the clothes away, Yunjing decided to wear this suit the next time he went to see Wu Qingmei. It was a little bit ugly, but it was better than the clothes that had been patched layer by layer when he was a child.

At first, my family was poor and couldn't afford new clothes. Most of Yunjing's clothes were made from adults' clothes. When they were older, I would add some fabric to make smaller clothes bigger. No matter how worn they were, I couldn't bear to throw them away. My mother, Jiang Susu, was very good at craftsmanship, even if she had to patch them up.

They can all sew beautiful patterns.

After catching a cold when she was a child, her mother, Jiang Susu, almost never let Yunjing leave her sight for many years. It was her mother's constant care that allowed Yunjing to grow up safely.

Thinking about it now, when I was a child, I was never separated from my family, but as I grew up, I spent less and less time with my family.

Well, Yunjing admits that he is a little homesick, even if he has been at home for a long time, his family members are very picky and disapproving of him...

The return journey moved forward rapidly as time passed. When night fell, they had already arrived at the border of Sanluo. In front of them was the wild forest at the junction of several countries.

Under the afterglow of the setting sun, Yunjing came outside and looked in the direction of Sanluo. After crossing the border, Yunjing felt an inexplicable sense of being at home. He had to admit that there was still a sense of alienation in a foreign country.

When they passed above the Great Wilderness Forest, Yun Jing paid special attention. After all, he could not see the eight-winged silver-backed centipede, but he did not experience the same 'crisis' as last time and was able to pass by safely.

Only after passing through the Great Wilderness Forest can we technically enter the territory of Dali. There are also people on the land, but the situation is still not optimistic due to the long-term drought.

The joy of suffering is that Dali does not have a treacherous organization like Sanluo to cause trouble, and even if the court disaster relief is properly carried out, the overall situation is much better than Sanluo, but there are still many refugees.

There is a shortage of water and food, especially when winter comes. The sun is shining brightly during the day but the nights are extremely cold. This winter is unbearable. I don’t know how many people will never get out of this winter.

If the curse burdened by the human race is not solved, the suffering in the world will further worsen. If this continues for another year or two, how many people in the world will be able to survive? 10% or 20%? That would probably be a terrible situation.

Picture!

Yunjing suddenly wondered, if that didn't work, could it be possible to boil the sea, raise the clouds and mist, and let the wind carry it to all directions to achieve rain?

Such thoughts are just a thought. How many clouds can he create even if he is exhausted? A drop in the bucket is an exaggeration. After all, the drought is not a local problem, it is all over the world, and his ability is limited.

In the cold winter, I'm afraid the only good thing is that the moisture in the air will occasionally stick to items and freeze after a night. If you collect them early in the morning, you can barely get some water, which can play a small role in the current water shortage situation.

"Wait a minute, the moisture in the air will stick to and freeze due to the low temperature. In other words, no matter how severe the drought is, there will still be water molecules in the air. Although it is a bit embarrassing to talk about science in this world that often does not talk about science, the fact is

There is moisture in the air, otherwise where would all the water go if the rivers all over the world dried up? Isn’t energy conservation a little bit more face-saving? Although face is not that big in this world.”

Suddenly, an idea flashed in Yunjing's head. Since the air contains moisture, can this moisture be collected and drunk?

Immediately, Yunjing quickly flipped through his past experiences, what he had seen and heard in his head, to see if he could find a solution.

People who survived in the wilderness in previous lives could find ways to collect water in the desert. Even though it was a small amount, there is no reason why they can't do it in this world.

I also forgot which country invented a device that can gradually collect water out of thin air when placed outside, which is enough for one or two liters a day. Regardless of the technological content, the method is advisable. What is the principle? I think carefully.

think.

Under the night, high in the sky, Yunjing stood on the bow of the ship, deep in thought, his brows sometimes frowning and sometimes relaxing. The green moon beside them deliberately reminded Yunjing that it was late at night, but they didn't dare to disturb him when they saw him thinking.

"I remember that in my previous life, the outdoor unit of the air conditioner would produce a lot of water when it was running, and it could even reach the level of a small flow. That was caused by the flow of air. As a result, the copper tubes, blades..."

Yunjing, who was deep in thought, had hundreds of thoughts flashing through his mind. He gradually came up with a general idea and his eyes gradually brightened.

In the middle of the night, Yunjing had a thought in his mind, and extended his mental power to search for things he could use on the ground below, and got them piece by piece from the air, bamboo tubes, wood, copper blocks...

When everything was almost collected, Yunjing continued to process, assemble and adjust these things. The wheel, blades, shell, crank handle...

Tubo and the others looked at Yunjing's work curiously, not understanding what he was doing at all, but they did not bother him in any way. They had a vague feeling that their young master was doing something big.

After constant assembly, adjustment, and reinvention, the details were improved bit by bit. In the end, Yunjing came up with a device that resembled an outdoor unit of an air conditioner, only one foot square.

Of course, this thing cannot be compared with a real air conditioner outdoor unit, but many of the principles are the same.

There is no electric drive, so he uses a hand-cranked method. Under the action of the gear, the blades in the device rotate very quickly when it is shaken. The combination of multiple wheels can rotate without much difference from the motor.

When it was almost dawn, Yunjing once again went to shake the finished product that had failed dozens of times. As the handle shook, the blades inside the device rotated wildly, driving the surrounding airflow to flow rapidly and invisible through the device...

Qingmei and the others looked at it curiously, not understanding what strange thing it was. For this thing, Yunjing actually worked attentively all night, and his concentration was even more serious than when he was reading and studying.

At first, the device had no effect at all. Yunjing continued to shake without giving up. As the world passed, Yunjing keenly discovered that the ground inside the device he made began to feel wet, and slowly water droplets condensed.

more and more!

Noticing this, Yun Jing smiled, even a little excited, knowing that he had succeeded.

His guess was right. According to the air flow away, the device in his hand can collect moisture in the air. According to his estimation, if the device in his hand does not stop, it is very simple to collect several liters of water a day for daily drinking.

enough.

"The water is coming out, Master, there is water inside." Qingmei, who was watching the whole process, couldn't help but cover her mouth and exclaimed. She felt it was so amazing, why did the Master shake the thing and water came out? She couldn't understand it, she couldn't figure it out.

Not to mention her, everyone else around her looked confused. Although the thing seemed ordinary, it gave them a shock that they couldn't describe in words.

Yun Jing said: "Isn't it good to have water? With this thing, if it becomes popular, people don't need to worry about not having drinking water in today's drought."

Hearing what Yunjing said, Tubo and the others realized where the inexplicable shock in their hearts came from.

This product can actually solve the problem of drinking water for countless people during drought. That is not a problem for one person, but for everyone.

At this time, they felt a numb scalp and wanted to say something, but anything they said seemed so pale.

Looking at the device that was still running in his hand, Yun Jing continued: "It is not difficult to create this thing. Ordinary craftsmen can create it after being familiar with it. It will be easy to promote it. You have all witnessed the process. It is not difficult to restore it, right?

So there is no need for me to tell San Luo that you all know how to do it yourself, right? I inform your majesty that the promotion of this product cannot be delayed without delay!"

"We will notify His Majesty as soon as possible." Tubo took a deep breath and said solemnly. This matter concerns all the people of the world and the stability of the country. How could we not take it seriously.

Qingmei realized in shock that they were loyal to Yunjing now, so she said hesitantly: "Master, how could you expose such an important thing to the public so casually? I know my thinking is wrong, but if this thing

If used well, it can bring you countless benefits."

"I know what you mean, Qingmei, but people can't live anymore. How can I be selfish and only consider my own interests? Besides, it's not that I'm conceited. Money and power are all things that are within easy reach for me.

This thing is beneficial to all people in the world, and the most important thing is that they can survive, so don't say this again in the future," Yun Jing shook his head and said.

"Qingmei knows I'm wrong," she quickly lowered her head and said, but Yun Jing's image suddenly rose to infinite heights in her heart.

At this time, Yunjing was struggling. With this device, people's drinking water problem has been solved, but what about food? What to do? It's just a pipe dream to grow crops with the little water produced by this thing.

Drinking water can also be collected from the air, but food cannot be created out of thin air.

But no matter what, one urgent problem can be considered solved at present. As for the other things, just take your time. You won’t become a big fat man with one bite.

In today's drought, Yun Jing can imagine how quickly the device in his hand will spread. This is a real life-saving thing!
