The next night, Liuhe Villa.

Yu Yalan used a planetarium to observe the weather conditions in the past seven days, and finally decided to carry out artificial rainfall tonight.

Yu Hongxuan and the eight puppets also accompanied Yu Yalan, responsible for serving as an assistant and lookout for Yu Yalan.

The secret guards of the villa formed a protective circle 300 meters away to patrol and prevent anyone from approaching the rainfall operation center.

Although they don't know how the future mistress will control the situation during this severe drought, they are still ready to keep it secret and protect it.

On the open ground in the center of the protective circle, Yu Yalan was carefully preparing on the operating table, and Yu Hongxuan was holding a tablet computer to monitor the changes in clouds and wind direction over Yanzhou in real time.

On the launch pad a few steps away from them, three small jets covered in pitch black were on standby, while eight puppets stood beside them, ready to obey the command and execute the operation orders.

After spending a lot of time on repeated debugging, the three rainmaking aircraft were finally launched into the sky at Yu Yalan's command.

The concealed aircraft quickly rushed into an altitude of three thousand meters and began to create a large number of clouds suitable for rainfall in the mid- and low-altitude areas.

Snow-white clouds spurted out from the tail of the aircraft, gradually forming large clouds to cover the night sky of Yanzhou. The layers continued to gather together, slowly showing the majestic momentum of black clouds overwhelming the city.

On the ground, Yu Yalan and others watched the operation nervously, and their hands were constantly controlling the trajectory of the rainmaking aircraft on the operating platform.

At present, everything is running smoothly, but they dare not slack off at all.

In fact, general artificial rainfall does not have the ability to create clouds. It only uses airplanes or rockets to send catalysts on cloudy days, and through physical or chemical reactions, the original clouds condense and turn into raindrops that fall to the ground.

The northwest has been suffering from drought for too long. There are far more clear and cloudless days than cloudy days. General artificial rainfall cannot be applied to this situation. Yu Yalan can only find other ways to solve the problem of lack of rain.

After studying for a long time in the space library, she found a rainmaking technology from advanced civilizations. She raced against time to learn the relevant knowledge, and she couldn't wait to start preparing for artificial rainfall.

Use the universal factory to create rain-making equipment, and then compress the Spirit Lake water in the space into the rain-making bomb. After the rain-making aircraft rushes into the sky, the Spirit Lake water in the rain-making bomb will turn into suspended clouds through physical reactions.

When sufficient cloud cover and moisture have accumulated, the aircraft will release catalysts for rainfall operations, ultimately completing the entire process of artificial rainmaking.

This kind of rainmaking technology is amazing, but it can only be used in one place. It is impossible to make rain in the whole province of Qinxi. Yu Yalan can't find enough fresh water resources at all.

Even the rain-making in Yanzhou is limited to this time only, and we will try to find cloudy days for artificial rain in the future. Although the spiritual lake water in the space can be slowly regenerated, it will consume the energy of the merit tree on a large scale.

It is difficult and ups and downs for them to accumulate merit, and they must not do things that are only a drop in the bucket. Otherwise, if the energy source of the space is damaged, they may fall into the dilemma of having nothing in the future.

The operation of artificial rainmaking is relatively complicated. Yu Yalan and her brother worked hard all night, and finally succeeded in making rain before daylight.

There were several shocking thunder booms, and a heavy rain poured down.

The entire Yanzhou Prefecture was suddenly awakened by the sound of thunder and rain, and the quiet early morning suddenly became boiling.

Although there was still an hour before morning wake-up, the people of Yanzhou couldn't help but rush out of their houses. When the cool rain really wet their cheeks, they truly believed the facts before them.

"It's raining——!"

People were excited to move out pots and pans from their homes, preparing to store some rainwater for daily use. The long-term drought has changed their living habits, and they were afraid that the next rain would be far away.

Many people took a shower in the rain, using the rain to wash away the accumulated dirt on their bodies. They didn't care whether they would get cold because of it. They just wanted to feel the long-lost moisture.

Fortunately, the rainfall produced by the water from Linghu Lake is beneficial to the human body without any harm, and the people who were exposed to the rain got the benefits of physical fitness by accident.

This rain only lasted for half an hour, but the entire Yanzhou Prefecture was filled with vitality.

After dawn, the heavy rain began to stop.

People rushed to the fields to check on the changes in the crops. They saw that the cracked land had returned to moisture, and the wilted sweet potato seedlings began to grow strong and green. People were happy, laughing loudly, and looking forward to the days ahead.

As unsung heroes who made silent contributions, the Yu Yalan siblings have now returned to space. Working all night has made them tired and sleepy, and they urgently need some sleep to relieve their tense spirits.

…

After sleeping happily for four hours and enjoying a sumptuous lunch, Yu Yalan regained her strength and spirit, and went with her younger brother to inspect the relevant situation in the city and in the fields.

The two entered the village in a carriage, and then walked easily on the loess road, with no specific destination in mind, just casually looking at the conditions in the fields.

Many people in Yanzhou recognized the two siblings. After all, one was Dr. Yu who often donated medicines and medicines, and the other was the Yu Dong family who generously donated money and sold rice at a fair price. Both of them had high reputations in Yanzhou, and they were prepared to do so.

Respected and appreciated by the people.

"Doctor Yu, Fu'an! Mr. Yu, Fu'an! Why are you free to come to our village today?"

Several villagers came forward to say hello with smiles, their faces no longer showing the sadness of the past.

Yu Yalan, wearing a light blue curtain hat, nodded gently in response, but did not say anything.

Since Song Xi took control of Yanzhou, she has not taken the Magic Pill to disguise herself, but in order to avoid accidents or trouble, she usually wears a curtain to hide her face.

She has a cold temperament. Apart from being able to relax in front of Song Xi and her brother, she will subconsciously be a little reserved and silent when facing strangers. When the villagers chat with her, she mostly just smiles and nods, and occasionally says

Two brief responses.

When two siblings are traveling together like this, Yu Hongxuan usually takes the initiative to act as a diplomatic ambassador, chatting enthusiastically and humorously with the interlocutor.

"It's nothing. I just saw a heavy rain in the early morning. I came out to see how the sweet potato seedlings are growing. Did you all catch the rain? The drought is not over yet. You must not be careless."

The villagers were a little surprised when they heard this, and there was a bit of uneasiness on their faces, "We have received all the rain, but...will the drought continue this year?"
Chapter completed!
