Chapter 289 Asking for Rain
His Majesty Li Er rode his horse to the top of the southern foot of Mount Li, and saw Taishi Ling Li Chunfeng looking up at the sky, chattering endlessly, dancing and not even coming over to salute, as if he was crazy...< br>
"I have seen Your Majesty!" Fang Jun quickly knelt down on one knee to welcome him.
"Stand flat!" His Majesty Li Er jumped off the horse, threw the reins to the guards behind him, glanced at Li Chunfeng who was in a strange state, and asked curiously: "What's going on?"
Fang Jun's mouth twitched. Could it be that he just wanted to popularize science, but he led this half-immortal astray? He could only say innocently: "I don't know, maybe I'm trying to figure out whether the clouds can bring rain..."
"Oh?" His Majesty Li Er perked up and raised his hand to stop the guards who were catching up behind him. He stood solemnly and did not allow "Li Shenxian" to be disturbed in his calculations...
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, moon and stars had a huge impact on the political life of the country, and hoped to establish connections and find patterns between celestial phenomena and human affairs. And this kind of insight into the secrets of heaven cannot be mastered by anyone without great wisdom!
Li Chunfeng is the first person in this field. Even his master Yuan Tiangang is only slightly better in Yin and Yang skills.
Li Chunfeng was still mumbling to himself crazily. Even Fang Jun wanted to interrupt him, but His Majesty Li Er stopped him...
There was a shouting and hoopsing at the foot of the mountain, but Cheng Yaojin and Hou Junji arrived almost at the same time. When the two of them came up the mountain, they found that the scene was a bit strange. When they saw His Majesty Li Er's gesture, they stood aside obediently and looked at each other, both of them seeing the other's surprise.
The wind on the top of the mountain is getting stronger and stronger, and Fang Jun is a little anxious. If it blows for a while, the clouds in the sky will disperse, and then it will be too late to do anything...
At this moment, Li Chunfeng suddenly heard a loud shout, turned around suddenly, pulled Fang Jun's arm, and shouted, "I know what the servant minister Fang did, why are you so embarrassed!"
< br>
Fang Jun, who was startled, said helplessly: "Li Taishi, please be patient. The wind is getting stronger and stronger. If you don't take action, I'm afraid..."
"It's the wind! It must be this wind, right?" Li Chunfeng's eyes were red and his expression was extremely excited. He pointed at the piles of talismans on the top of the mountain and said loudly: "This south wind is extremely humid and contains a lot of water vapor. , the chambermaid must be thinking of something Burn these talismans to light a fire, and the fire will move upward, sending the south wind containing a large amount of water vapor into the clouds, so as to achieve the purpose of Yin Qi prevailing over Yang Qi, thus causing rainfall. This is it, it must be this way, for Wrong? ”
You still have some understanding, but it’s a pity that you understood the wrong thing...
We want to use the south wind to send these talismans to the sky. Your cause and effect relationship 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 paper, it is simply not worth mentioning...
Fang Jun turned to His Majesty Li Er and said loudly: "Your Majesty, please preside over the rain praying ceremony!"
What kind of ceremony is this? It’s nonsense, it’s nothing more than an extremely clumsy artificial rainfall...
His Majesty Li Er shook his head: "You will preside over it!"
Fang Jun didn't think about why His Majesty Li Er gave up this opportunity to show off. He was afraid that if he delayed any longer, the clouds in the sky would really disperse. He immediately straightened his back and walked towards the two thousand soldiers who stood solemnly. Death.
"Light the fire!" Fang Jun ordered coldly.
The basic procedures have been arranged countless times, so there will be no mistakes.
However, he saw countless fire folds being lit in the hands of the soldiers. As soon as the swaying flames touched the talismans that had dried to the extreme, a puff of flames suddenly burst into flames. Just as a gust of south wind blew by, the fire took advantage of the wind, and the orange-red flames jumped up high, jumping happily. The wind helped the fire, and the entire top of the mountain instantly turned into a sea of fire.
The south wind blows from the open area in the south, and when it reaches the foot of Lishan Mountain, it forms an updraft due to the obstruction of the mountain. When we reach the top of the mountain, because the resistance disappears, this updraft should have calmed down and blown along the top of the mountain. But now the top of the mountain is a sea of fire, and the airflow is heated, and once again carries the sparks all the way up, directly into the dark clouds!
The flames soaring into the sky made the faces of the people on the top of the mountain turn red. The power of this fire, which was aided by the wind, shocked everyone!
Immediately afterwards, Fang Jun shouted: "Bang the drum!"
After lighting the talisman paper, the soldiers who had retreated to the surroundings heard the words and immediately took out the large drums and small drums prepared in advance and various musical instruments that could make sounds, and started beating in a unified rhythm with "dong dong dong wu wu wu"!
Suddenly, the flames on the top of the mountain soared into the sky, and the sound of drums shook the sky!
The momentum is mighty, with the spirit to compete with the heaven and earth!
In the history of various countries around the world, there are records of rain immediately following prayers.
Are you really moved by the heaven to send down the rain? Or is it just a coincidence?
In fact, it is not the case. Don’t think that praying for rain in ancient times is just 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. The more it spread, the more biased it became...
Ancient Taoist priests burned silver powder characters to produce fine silver powder particles, which were lifted up by hot air and carried into high-altitude clouds and mist. Silver powder has good conductivity and can be used as agglomeration nuclei to absorb water vapor and accumulate water vapor to form water droplets. Here, a simple version of artificial rainfall.
But they themselves couldn’t explain what was going on, so they lied and claimed that they had invited the Dragon King and gave him silver powder and money. The Dragon King was so happy that rain naturally fell... Being greedy, it also improves the force level by the way. It's like killing two birds with one stone.
Modern methods use aircraft rockets or rainfall bombs to send silver iodide into the clouds, instead of the old way of sending money to the Dragon King. Silver powder particles have good conductivity and act as accumulation nuclei to accumulate water vapor and fall in the form of water droplets. This is a very simple principle of artificial rainfall. .
It's just that Fang Jun didn't know how to get silver iodide. There was a lot of silver, and the content of iodine in kelp was particularly high, so he bought a large amount of kelp along the coast, and then it turned out that Guanzhong combined it with silver...
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 within the cloud. Generally speaking, the colloid state of water vapor in clouds is relatively stable and it is difficult to produce precipitation. Artificial rainfall enhancement is to destroy this colloid stable state.
The usual artificial rainfall is to use certain means to spread catalysts in the medium and low cloud systems with relatively large cloud and fog thickness to achieve the purpose of rainfall. The first is to increase the number of condensation nuclei in the cloud, which is beneficial to the collision and enlargement of water vapor particles; the second is to change the temperature in the cloud, which is beneficial to disturbance and the generation of convection.
Therefore, Fang Jun’s method of burning a large amount of paper talismans is not known whether it can produce silver iodide rainfall, 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 this is just a theory. Fang Jun, a chemist and physicist who knows how many knives to use, just uses the principles he knows to change the structure of the clouds as much as possible.
Logically speaking, the effect must be there, but whether it will reach the level of rainfall, only God knows...
The ancients were in awe of "Heaven" and the natural world, and the so-called "Tian Shui" should not be taken arbitrarily.
The idea that "man can conquer nature" is a manifestation of mankind's 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 power of heaven and earth, ant-like human beings can actually do very little...
Man can only adapt to Heaven, but cannot conquer Heaven.
Just like artificial rainfall in later generations, no matter how advanced the method is, it depends on one prerequisite, which 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 will be exhausted and still won't be able to produce any rain...
Li Chunfeng had calmed down and stared blankly at the sparks in front of him that were flying high into the sky with the south wind and seemed to have penetrated into the clouds. He felt a magical power gathering in his chest. There seemed to be a magical door slowly opening in front of him.
Then, feeling a little cool on my face, I subconsciously reached out and touched a trace of water stain... (End of Chapter)
