Li Chunfeng has been a little busy lately!

It has not rained for a long time in Chang'an City.

At the beginning, no one cared about it.

After more than ten years of good weather in the Tang Dynasty, everyone seemed to have forgotten the famine.

In addition, the granaries of each household are full of food, so there is no need to worry about being hungry.

In this way, at the beginning, this year's drought was not taken seriously.

It seemed that something was wrong, and everyone started to be a little anxious.

At this time, the Taishi Bureau where Li Chunfeng was located became busy.

The rain prayer activity is a small venue for three days and a large venue for five days.

However, it seems useless.

It was under this situation that Li Kuan returned to Chang'an City.

For some reason, Li Chunfeng came to the door as soon as he heard the news.

"Your Highness of the King of Chu, Guanzhong is relatively dry this year, and the crop harvest has been affected. The Taishi Bureau has organized several large-scale rain praying activities. His Majesty has also bathed and fasted for several days, but it has not worked. Do you have any good suggestions?"

After Li Chunfeng finished speaking, he looked at Li Kuan with anticipation.

"Drought has been encountered countless times in all dynasties, and the way the officials in the court handled is relatively appropriate. Now we must ensure that the granaries in various parts of Guanzhong have grain, the grain reserves in each grain shop are relatively sufficient, the prices are relatively stable, and we can do very limited other things."

Li Kuan's words disappointed Li Chunfeng a little.

In fact, Li Kuan is even more depressed.

Isn’t you Li Chunfeng one of the most famous charlatans in the Tang Dynasty?

What can I do if I can’t even do anything about you?

Isn’t this the time to test the weather forecast?

Could it be that you can still make artificial rain?

"Your Highness, King of Chu, don't you have any good solutions. Can you make it rain?"

Over the years, Li Kuan has done too many incredible things.

Whether it is Li Shimin or other ministers, when they encounter some difficult and complicated problems, they will think of Li Kuan.

"The formation of this rain is a natural phenomenon in nature. The water vapor in the air is condensed into water points at a high altitude. Small water points collide and merge, and gradually become larger and larger. When the buoyancy of the air can no longer be supported, it will land. This is raining.

In the early stages of raindrop formation, small raindrops mainly rely on continuously absorbing the water vapor around the cloud to condense and condense themselves. At this time, if the water vapor energy source in the white clouds is constantly supplied and replenished, and the surface of the cloud droplets is often in a supersaturated state, then this condensation process will continue, causing the cloud droplets to grow continuously, becoming raindrops, and allowing the rainfall to continue.

Nowadays, the climate in Guanzhong is dry, and the water vapor that can rise to the air on the ground naturally decreases. If the water vapor in the white clouds is not enough, there will be no way to form raindrops. Only when it accumulates to a certain extent will rain precipitate.

Unless you can find a way to speed up the condensation speed of the water vapor in the white clouds, you can make it rain heavily in the sky. Otherwise, we have no choice but to wait."

Li Chunfeng's son Li Yan is now working on steam engine research for Li Kuan at the Steam Engine Research Institute of Guanshishan Academy, so Li Kuan is still relatively patient with Li Chunfeng.

It’s not that I don’t want to help, but I haven’t found any good way to help.

"The Great Biography of the Book of Documents: Five Elements" says: Heaven produces water, earth produces fire, heaven produces wood, earth produces metal. Earth produces sixty-fourths of water, heaven produces fire, earth 80% of wood, heaven produces metal, heaven produces earth. What you said seems to be very different from this."

A bunch of words appeared in Li Chunfeng's mouth that made Li Kuan's head big, and he couldn't understand them at all.

Sometimes these people like to use the words of hundreds of years ago to reason, so people don’t want to continue listening.

"Guanshishan Academy has a Meteorological Research Institute and a special observatory. I suggest you go there to talk to the brothers Zhu Yin and Zhu Tong. Their research on climate is the most profound. Judging from the past, their predictions of weather can reach 80%.

When it will rain next time, the Taishi Bureau will arrange rain prayers and there will be no need to worry about the event being held for so long, but there will be no effect at all."

Li Kuan naturally knew why Li Chunfeng was under such great pressure.

Every time I pray for rain, I am so mobilized, but the result was nothing.

As the number of times increased, everyone's sense of trust in Taishi Bureau became worse.

If everyone doesn’t believe you, the Shishi Bureau, how can they carry out their work in the future?

To put it bluntly, it means that the Taishi Bureau is about to fall out of favor.

How can Li Chunfeng not be in a hurry?

"I have also gone to Zhu Yin and Zhu Tong to find them. According to them, there will be no heavy rain in Chang'an City in the next month, and even in the next three months, there will be no decent heavy rain. If this is the case, it will be troublesome."

Li Chunfeng has seen people who have experienced droughts. The scene of people changing their children to eat is heartbreaking to think about it.

Although there is only a drought in Guanzhong, other places are still in good weather and will not have too much impact on the annual grain output of the Tang Dynasty.

But, nowadays, who would dislike too much food?

The Chinese nation has been around for five thousand years, and there has never been a time when it dislikes too much food.

“There will be no heavy rain in the next three months?”

Li Kuan was also a little surprised when he heard Li Chunfeng's words.

This situation seems to be more serious than I imagined.

In history, it seems that there was no major disaster in the 18th year of Zhenguan.

"Yes, Zhu Yin and Zhu Tong said so! Your Majesty only learned about this situation yesterday, and is very anxious now. Otherwise, I wouldn't have come to visit you immediately as soon as I hear you come back."

Li Chunfeng's attitude should be as sincere as he should, which made Li Kuan feel a little embarrassed to stand by and watch.

In later generations, when encountering severe droughts, artificial rainfall is often considered.

But these days, there are neither rockets to launch nor aircraft to perform artificial rainfall.

What should I do if I change it myself?

Li Kuan fell into deep thought.

It is very difficult to carry out artificial rainfall.

But if it is done, it seems that the impact will be huge.

At that time, it will inevitably make some people more taboo about themselves.

But if this weather is allowed to develop, then the grain harvest in Guanzhong this year will be really ruined.

If you can make a rain, you can at least ease the tense atmosphere.

Even if it does not help the actual growth of crops, the meaning is extraordinary.

"You go to Guanshishan Academy Observatory with me. I will talk to Zhu Yin and the others and see what to do!"
