Fang Jun felt furious when he saw Li Chunfeng.
I thought to myself, could it be that this magic stick really saw something?
There was no other way. Fang Jun could only quickly change the subject and said: "Taoist Master, let's hurry up the mountain. Since you are here to learn about artificial rainfall, don't delay..."
After saying that, he went directly to the mountain.
Fang Jun decided to withdraw first after handing over the steps of artificial rainfall to this guy.
Staying with such an old bastard makes me feel flustered!
Li Chunfeng was stunned and couldn't understand why Fang Jun was doing this!
But seeing Fang Jun running away, he could only take steps to catch up.
After a while, the distance between him and Fang Jun became closer and closer.
Seeing this scene, Fang Jun's face turned pale with fright.
Dear sister, this guy is indeed a living god!
He ran so fast, and it only took a few breaths for the opponent to catch up. Could it be that he really knew some magic?
Thinking of this, Fang Jun was so frightened that he almost lost his soul, and he quickly used all his strength to suck the milk.
He felt that he would feel safe only when he reached the top of the mountain and there were more people!
Fortunately, after reaching the top of the mountain, Li Chunfeng did not pester him too much, but turned his attention to artificial rainfall.
Fang Jun suppressed the fear in his heart and asked everyone to prepare for artificial rainfall.
At this time, Fang Jun seemed to be as stable as a rock, but in fact he was a little absent-minded.
However, everyone cooperated tacitly.
Soon, dark clouds rolled and gathered overhead.
It seems that a rain is coming soon.
Li Chunfeng stood on the top of the mountain, happily watching the thickening clouds in the sky and feeling the changes in the weather.
"Oh, the clouds are gathering and the water vapor is gathering. This is a sign of rain!"
"The Prince Consort can indeed make it rain from the sky. I thought His Majesty was lying to me..."
Li Dasheng was delighted for a while and sighed for a while.
Finally, Li Chunfeng asked like a student: "Can you tell me why you can make these clouds stay and turn them into rain?"
"According to my inference, it will not rain in Guanzhong within a month, because these clouds will be blown away by the strong wind..."
Fang Jun was secretly surprised.
This guy really has some skills!
If I hadn't created such artificial rainfall, these clouds would have been blown away by the strong wind very quickly, and it would have been impossible for it to rain in Guanzhong.
However, as long as this guy's focus is not on himself, Fang Jun is happy to explain.
"Daozhang Li, do you think there are clouds every time it rains? Why do these clouds condense into rain? Where does this rain come from?"
After thinking about it, Li Chunfeng said: "When clouds gather, it rains, and when clouds disperse, there is wind. Yin and Yang alternate between heaven and earth. When Yin Qi is strong, it rains, and when Yang Qi is strong, wind..."
Li Chunfeng talked like a master.
But his answer left Fang Jun confused...
He can't understand this Yin-Yang theory at all, okay?
As a time traveler, of course you cannot give in.
So Fang Jun blinked and nodded pretending to be calm.
All right!
I don't know how to refute your answer.
However, I can also tell you about the formation process of precipitation.
So Fang Jun told Li Er the same story again.
"In the clouds, as the water vapor in the air continues to be replenished, the supersaturated water vapor continues to condense and sublime on the cloud droplets..."
"The cloud droplets continue to grow. When they increase to a certain extent, the cloud droplets begin to fall due to the effect of gravity. During the falling process, large cloud droplets fall quickly, while small cloud droplets fall slowly."
"Therefore, large cloud droplets will catch up with small cloud droplets and merge into larger cloud droplets. If this continues, the cloud droplets will gather larger and larger like snowballs, and eventually fall to the ground and become raindrops..."
After hearing these remarks, Li Chunfeng was immediately confused.
Because he didn't understand Fang Jun's theory at all.
After thinking for a while, Li Chunfeng asked: "How do you know the changes in the clouds? Can't you see it with your own eyes?"
"Well……"
Fang Jun was speechless.
There are currently no experiments to prove this theory.
Obviously, Li Chunfeng regarded himself as a monster.
After all, in his eyes, if he was not a monster, how could he see what was happening in the clouds in the sky?
There was no other way, so Fang Jun had no choice but to educate Li Chunfeng on science.
He didn't want to be regarded as a monster, especially this old bastard.
Therefore, Fang Jun followed the temptation.
"One hot day, I was playing by the river and I noticed something very strange."
"Once, I dug a small pit by the river and filled it with water. But in the afternoon, I found that the water in the pit was much shallower. I checked and found that the pit was not leaking. Taoist priest, tell me, where did this water go?"
"What's this? Naturally, it evaporates after being exposed to the sun. Let alone a small puddle. If the sun is always shining directly, the water level of rivers and lakes will also drop, and it will evaporate due to heat."
Li Chunfeng looked like he didn't know this bit of common sense.
"hehe!"
Fang Jun ignored his contempt and continued to ask: "Then, where did the water go?"
This time it was Li Chunfeng's turn to be stunned and said subconsciously: "If it's gone, it's gone. Where else can it go?"
Fang Jun raised his head and looked at the clouds: "Then let me ask you again, why is there rain in these clouds, and where does the rain come from?"
"Clouds gather into rain?"
"hiss……"
"Don't you mean to say that...the rain in these clouds is the water evaporated by the sun?"
Li Chunfeng's face was full of disbelief.
While this hypothesis completely subverted Li Chunfeng's outlook on life, it also made his mind suddenly light up!
He is the world's most outstanding mathematician and astronomer...
Moreover, he has been indoctrinated in Taoist theory since childhood and is well versed in the Taoist theory of yin and yang.
In his view, the entire world is nothing more than a combination of yin and yang.
Tai Chi gives birth to two things, and two things give rise to all things!
Where does the rain come from?
If it were in the past, Li Chunfeng would naturally have just said to Fang Jun that the two qi of yin and yang alternate between heaven and earth. If the yin qi is strong, it will rain, and if the yang qi is strong, it will be wind...
But now that Fang Jun was explaining from a micro perspective, Li Chunfeng suddenly found an explanation that was more consistent with the principles of heaven and earth.
Water is yin. The water on the ground is evaporated by the sun, then disperses in the sky, and then condenses into clouds. Then the clouds gather and turn into rain and fall to the ground.
Over and over again!
Isn’t this process the harmony of yin and yang, the cycle of immortality?
Thinking of this, Li Chunfeng took a breath of cold air.
Only this truth can make sense.
This is why clouds gather before every rain.
Seeing that Li Chunfeng had figured it out, Fang Jun continued to guide.
"Let me ask you again, if the hypothesis just now is true, then there will be water vapor in the sky all the time. How can we explain that sometimes it rains and sometimes it doesn't?"
Li Chunfeng's brain was running at high speed, but he still couldn't figure out his thoughts.
Not to mention whether Fang Jun's assumption is correct or not.
According to the idea of alternation of yin and yang, this problem can be explained!
"The water on the ground turns into water vapor, and when the water vapor in the sky gets bigger and bigger, it turns into rain. This cycle repeats itself, which is the perfect principle of heaven and earth!"
Fang Jun was dumbfounded.
Let me tell you the principle of water vapor condensing into rain. Why are you talking about these yin and yang theories?
But it seems to make sense, but it’s very macroscopic.
So Fang Jun had no choice but to say again: "What you said makes sense..."
"Let me ask you again, now that you know where the rain comes from, how do you make it rain from the sky?"
Li Chunfeng said excitedly: "You only need to dry out the water in the rivers, lakes and seas in the world to increase the amount of water vapor in the sky. As long as the water vapor increases and condenses into clouds, it will be when the Yin Qi is at its peak, and it will naturally rain!"
Fang Jun was stunned, but speechless!
To dry up the water in rivers, lakes and seas?
Only an old bastard like you can figure it out, why are you roasting it?
Is this an evaporation process?
But Li Chunfeng gave such an explanation!
From a theoretical and principle perspective, you have to admit that there is absolutely nothing wrong with it!
Alas, it is undeniable that our ancestors did have a thorough understanding of the principles of heaven and earth.
Unfortunately, some scientific practices are missing.
