Tiantang Splendid

Chapter 289
His Majesty Li Er rode his horse to the top of the southern foot of Lishan Mountain, and saw Tai Shi Ling Li Chunfeng raised his head and looked up at the sky, talking endlessly, dancing and dancing, and didn't even come to salute, looking crazy...

"My minister has seen His Majesty!" Fang Jun quickly knelt down on one knee and greeted him.

"Pingshen!" His Majesty Li Er jumped off his horse, threw the reins to the guards behind him, glanced at Li Chunfeng who was in a strange state, and asked in surprise, "What's wrong?"

The corner of Fang Jun's mouth twitched. Could it be that he just wanted to popularize science, but led this half-fairy astray?He had no choice but to say innocently: "I don't know, maybe I'm trying to figure out whether the clouds can bring rain..."

"Oh?" His Majesty Li Er lifted his spirits, raised his hand to stop the guards who were catching up behind him, and stood in awe, not allowing to disturb "Shenxian Li" to calculate the secret...

His Majesty Li Er has great trust in Li Chunfeng.

This is not only because of Li Chunfeng's superb arithmetic attainments, but more importantly, his achievements in astronomy and calendar!The ancients believed that the movement of the sun, the moon and the stars had a huge impact on the political life of the country, and hoped to establish connections and find laws between astronomical phenomena and human affairs.And this kind of technique of insight into the secrets of heaven cannot be mastered by non-great wisdom!
And Li Chunfeng is No. 1 in this aspect, even his master Yuan Tiangang is only slightly better in the number of yin and yang.

Li Chunfeng was still muttering madly to himself, even Fang Jun wanted to interrupt him, but was stopped by His Majesty Li Er...

There was a whimper at the foot of the mountain, but it was Cheng Yaojin and Hou Junji who arrived almost at the same time.The two came up to the mountain, but found that the scene was a bit strange, and seeing His Majesty Li Er's gesture, they stood obediently on one side, looked at each other, and both could see each other's surprise.

The wind on the top of the mountain is getting stronger and stronger, Fang Jun is a little anxious, if it blows for a while, the clouds all over the sky will disperse, and then it will be too late...

At this moment, Li Chunfeng suddenly yelled, turned around suddenly, pulled Fang Jun's arm, and shouted, "Pin Dao knows what Fang Shilang is doing, why are you fighting like this!"

The startled Fang Jun said helplessly: "Li Taishi, please be safe and don't be impatient, the wind is getting stronger and stronger, if you don't act, I'm afraid..."

"It's the wind! It must be this wind, isn't it?" Li Chunfeng's eyes were red and his expression was extremely excited. He reached out and pointed to the mountains of talisman papers on the top of the mountain, and said loudly: "This south wind is very humid and contains a lot of water vapor. , Fang Shilang must want to ignite these talisman papers to ignite a big fire, and the fire will rise up, and then send the south wind containing a lot of water vapor into the clouds, so as to achieve the purpose of Yin Qi surpassing Yang Qi and thereby raining, that's it , that must be the case, right?"

It's still a bit savvy, but it's a pity that you understand it the wrong way...

We are going to use the south wind to send these talismans to the sky. Your causality is wrong. No matter how humid the south wind is, how much water vapor can it carry?Compared with the silver iodide in this talisman spirit text, it is nothing worth mentioning...

Fang Jun turned to His Majesty Li Er, and said loudly, "Your Majesty, please preside over the ceremony of praying for rain!"

What a big ceremony, it's nonsense, but it's just an extremely clumsy artificial rainfall...

His Majesty Li Er shook his head: "You are here to host!"

Fang Jun didn't even think about why His Majesty Li Er gave up this opportunity to show off. He was afraid that if he procrastinated, the clouds would disperse. pawn.

"Light it up!" Fang Jun ordered coldly.

The basic procedures have already been arranged countless times, so that there will be no mistakes.

But seeing countless fire folders being lit in the hands of the soldiers, the shaking flames just touched the extremely dry talisman papers, and suddenly a cloud of flames burst out.Just a gust of south wind blew by, and the fire took advantage of the wind, and the orange-red flame jumped up and jumped happily.

The south wind blows from the open place in the south and reaches the foot of Lishan Mountain. Because of the blocking of the mountain, an updraft is formed.When we got to the top of the mountain, because the resistance disappeared, the updraft should have calmed down and blown along the top of the mountain, but now the top of the mountain was covered in a sea of ​​flames, and the airflow was heated, and once again carried the sparks all the way up, directly drilling into the dark clouds!
The soaring flames made the faces of the people on the top of the mountain crimson, and the overwhelming momentum of the fire with the help of the wind and the power of the wind was shocking to everyone!
Immediately afterwards, Fang Jun shouted: "Beat the drum!"

After igniting the talisman paper, the soldiers who had retreated to the surrounding area heard the words, and immediately took out the big drums and snare drums prepared in advance and various musical instruments that could make sounds, and beat them in a unified rhythm with "dong dong dong woo woo woo"!
All of a sudden, flames shot up to the sky on the top of the mountain, and the sound of drums shook the sky!

The momentum is mighty, and there is a spirit of competing with the world!
In the histories of countries all over the world, there are records that after praying for rain, it will rain.

Is it really touched by the rain from the sky?Or just a coincidence?

In fact, it is not. Don’t think that the ancient prayer for rain is just a superstition. In fact, there are some scientific reasons. It’s just that the ancients couldn’t explain it clearly. They knew it but didn’t know why.

Ancient Taoist priests burned silver powder characters to produce fine silver powder particles, which were lifted by hot air and carried to high-altitude clouds and mist. Silver powder has good conductivity and can be used as an accumulation nucleus. It absorbs water vapor and accumulates water vapor to form water droplets. Here, a simple version of artificial rain.

But they themselves couldn't explain what was going on, so they lied that they had invited the Dragon King and sent silver powder money to the Dragon King. Greedy, and incidentally raised the level of compulsion, killing two birds with one stone.

In modern times, aircraft rockets or rainfall shells are used to send silver iodide to the clouds, which replaces the old way of sending silver coins to the Dragon King. The silver powder particles have good conductivity, and as the accumulation nucleus, water vapor accumulates and falls in the form of water droplets. This is a very simple artificial rainfall principle. .

It’s just that Fang Jun didn’t know how to get silver iodide. There is a lot of silver, and the iodine content in kelp is very high, so he bought a large amount of kelp along the coast, and then combined it with silver in Guanzhong...

Clouds are formed by the condensation of water vapor; the thickness and height of clouds are usually determined by the amount of water vapor in the cloud, the number of condensation nuclei, and the temperature inside the cloud.Generally speaking, the colloidal state of water vapor in clouds is relatively stable, and it is not easy to produce precipitation. Artificial precipitation is to destroy this stable colloidal state.

The usual artificial rainfall is to spread the catalyst in the middle and low cloud system with relatively large cloud thickness by certain means to achieve the purpose of rainfall.One is to increase the number of condensation nuclei in the cloud, which is beneficial to the collision and increase of water vapor particles; the other is to change the temperature in the cloud, which is beneficial to disturbance and convection.

Therefore, Fang Jun’s method of burning a large amount of talisman papers can produce silver iodide rain, but it will definitely cause convection in the clouds, and the disturbance and convection in the clouds will be more conducive to the collision of water vapor. When the updraft in the air cannot withstand the floating of water vapor particles, rainfall occurs.

Of course, all these are just theories. Fang Jun, a second-rate chemist and physicist who doesn’t know how many knives, just uses the principles he knows to change the structure of the cloud layer as much as possible.

Logically speaking, there must be an effect, but whether it will reach the level of rainfall, only God knows...

The ancients were in awe of "heaven" and the natural world, so the so-called "heavenly water" should not be taken arbitrarily.

The idea that "man will conquer nature" is the manifestation of human blind arrogance and ignorance after the emergence of modern science.The more technology develops, the more human beings understand their own insignificance. In the face of the majesty of heaven and earth, human beings like ants can actually do very little...

People can only adapt to the sky, not conquer the sky.

Just like artificial rainfall in later generations, no matter how advanced the method is, it must depend on a prerequisite, that is, the thickness of the cloud layer.If God doesn’t give you a thick cloud, even if you shoot all over the sky, you won’t be able to make it rain even if you’re exhausted…

Li Chunfeng had already calmed down, staring blankly at the Martian who seemed to have penetrated into the clouds as he rushed up to the sky with the south wind, and felt a magical power condensed in his chest.It seemed that there was a magical door slowly pushing open in front of him.

Then, with a chill on his face, he subconsciously stretched out his hand and touched a trace of water stains...
