Ran Fang did not refuse, nodded slightly, and said firmly: "Yes."
Now Zou Yixiu really couldn't sit still. He stood up and walked to the middle, bowing deeply towards Ran Fang.
"Sir, please enlighten me."
After saying that, the moment he raised his head, there was some expectation and gratitude in his eyes, and he looked at Ran Fang with burning eyes.
Seeing how sincere he was, Ran Fang smiled and said softly: "As I said just now, the reason why the Yin and Yang family is not valued by people is because they cannot have any good influence on people's lives."
"So, as long as this is changed, people's views on the Yin Yang family will be very different."
Zou Yixiu sighed deeply and stood there a little decadently.
Why don’t the people of the Yin and Yang family understand this?
But if there was a way to change it, would they still watch the Yin Yang family decline?
"What the commander said is right, but it's hard to change!"
"What we have learned and mastered are those things. Do we need to learn other things again?"
Looking at his sad face, Ran Fang smiled and shook his head.
It’s really a treasure that you don’t even know about.
He looked at Zou Yixiu and said seriously: "The Yin Yang family has a lot of knowledge, and it can be used by everyone from the common people to the Qin Dynasty, but you don't know it."
Seeing Zou Yixiu's confused look, Ran Fang took the initiative to explain: "The most direct thing is, one is to observe the sky, and the other is to master geography."
"You could possibly do it?"
"That's natural!" Zou Yixiu said so proudly that his chest even puffed up unconsciously.
But he soon bent down again and said a little decadently: "So what?"
Ran Fang didn't seem to hear his next words. He looked at the other people present and said: "Observing the sky is to predict the weather today and the day after tomorrow to see whether it will be windy, rainy, or rainy." Snow waits.”
"If this news can be spread every day, then people can take precautions in time and decide what to do the next day."
"Don't underestimate these things. If heavy rain or snow can be predicted, then when there is a severe drought, flood, or snow disaster, the people can be notified in advance to take precautions."
"In this way, Da Qin can also have some food and grass left for disaster relief. Isn't it a good thing?"
"And in autumn and winter, it can also remind people to harvest grain and grass in time to avoid frost."
Everyone present nodded and acknowledged Ran Fang.
None of them had thought about these issues, and even Zou Yixiu was a little surprised. Is his Yin-Yang theory still of such great use?
But after thinking about it, Ran Fang was indeed right, they can do it!
"What the commander said is true, it is true."
"But these are all trivial matters. If there is really a big flood, even if it is known in advance, it will only increase people's panic."
“How can we contend with God?”
This idea is deeply rooted in everyone's hearts, and Ran Fang doesn't think there is any problem with what he said.
However, he did not agree.
He looked at the people present firmly and said: "You are wrong. I always believe that man can conquer nature!"
"In the face of natural disasters, it may seem that we are powerless and only have the chance to die."
"But that's not the case. Just like the floods in Sishui County, you can build canals to change the flow direction of the rivers and reduce the losses caused by floods."
"If we can predict floods in advance, we can build a dam to store part of the flood water, or we can release some water from the river in advance before the flood arrives, and then we will be able to absorb the rainwater."
"Isn't this a good idea?"
"If heavy snowfall is predicted in advance, we can also prepare more items to keep out the cold and tell people to go out less, so that they can get through it. Isn't that okay?"
"There are also strong winds and ground dragons turning over. As long as we can predict them in advance, we can reduce some of the casualties."
Ran Fang spoke these words very slowly, and everyone present listened attentively.
If it is true as Ran Fang said, it will definitely be a good thing for Da Qin.
But is the Yin Yang family really that powerful?
Everyone present looked at Zou Yixiu.
Zou Yixiu, who was being watched, lowered his head in embarrassment and said in a heavy voice: "This..."
"The Yin Yang family can indeed predict the stars, but they can't guarantee that they will be accurate every time."
"Furthermore, as the commander said, predicting the turning of the earth dragon and predicting strong winds, these... I'm afraid they can't be done."
Everyone present looked disappointed. They really thought they could see what Ran Fang said.
Ran Fang smiled and said: "No one can be accurate. There is room for error in this kind of thing."
After all, even the most authoritative weather forecasting department later was not that accurate.
He continued: "It may not be possible to do it manually, but if you use some instruments, you can partially do it."
"As far as I know, there is a thing called a seismometer, which can predict or know the general direction of the earth dragon's turn. Wouldn't it be possible to move people in advance?"
"This is the use of observing the sky. As long as it is used properly, it will be a good thing for the people and the Qin Dynasty."
These few words completely aroused Zou Yixiu's interest. He had never heard of these things, and he was immersed in the picture Ran Fang said for a while.
Gu Siyuan, who was very interested, couldn't wait to ask after hearing what Ran Fang said: "What about geography?"
"What is this?"
Ran Fang thought for a while before speaking: "Mastering geography means mastering the mineral resources that Scorpio loves and knowing the general trend of the world."
"Especially some resources that are beneficial to the development of Daqin, such as iron ore, coal mines, copper mines, and undiscovered salt fields and salt ponds. These are all related to the lifeblood of Daqin."
"If the Yin Yang family can do this, are they still worried that the Yin Yang family will not be able to enter His Majesty's eyes? Will there be people who won't accept it?"
Ran Fang said the last sentence while looking at Zou Yixiu, as if waiting for his answer.
Zou Yixiu lived up to expectations, with strong interest in his eyes, and seemed to have inexplicable respect for what Ran Fang said.
If it is true, then the Yin and Yang family will be firmly established among hundreds of schools, and there is no need to worry that anyone will not want to learn.
"Sir, you just said that there are seismographs to observe the turning of earth dragons, but I have never heard of this."
"Also, I don't know what is needed for observing the sky and studying geography."
"Sir, please enlighten me."
Completely different from his reaction when he heard Ran Fang say he could see the moon just now, Zou Yixiu's attitude now was very sincere.
Ran Fang did not embarrass him and said generously: "It's very simple. There are windmills and anemometers to measure wind speed, and an armillary sphere to observe the sky."
Even though he didn't understand what these were, Zou Yixiu nodded first.
Then, he asked with some embarrassment: "What about...the one who looks at the moon?"
