Ran Fang didn't refuse, nodded lightly, and said with certainty: "Yes." ”

Zou Yixiu really couldn't sit still at this time, he stood up and walked to the middle, and bowed deeply towards Ran Fang.

"Please sir."

After speaking, the moment he raised his head, there was still some expectation and gratitude in his eyes, and he looked at Ran Fang with burning eyes.

Seeing that he was so sincere, Ran Fang smiled and said softly: "I also said just now that the reason why the Yin and Yang family is not valued by people is because he can't have any good impact on people's lives. ”

"So, as long as this is changed, then people's views on the Yin and Yang family will be very different."

Zou Yixiu sighed deeply and stood in place a little decadently.

Why don't the people of their Yin and Yang family understand this truth?

But if there is a way to change, will they still watch the Yin and Yang family decline?

"What the commander said is right, but it is difficult to change!"

"What we have learned, what we have learned, what we have learned, is it necessary to relearn other things?"

Looking at his sad face, Ran Fang shook his head with a smile.

It's a treasure that you don't know it.

He looked at Zou Yixiu and said very seriously: "There is a lot of knowledge in the Yin and Yang family, and it can even be used from the common people to the Great Qin, but you don't know it." ”

Looking at Zou Yixiu's puzzled eyes, Ran Fang took the initiative to explain: "The most direct thing is that one is to observe the heavens, and the other is to grasp the geography. ”

"You can do it?"

"That's nature!" Zou Yixiu said proudly, and even his chest unconsciously straightened.

But soon he bent down again, and said a little decadently, "So what? ”

Ran Fang didn't seem to hear his next sentence, looked at the others present and said, "This observation of the sky is to calculate the weather of tomorrow and the day after tomorrow today, to see if the weather is windy, rainy, snowy, etc. ”

"If the news can be spread every day, then the people will be able to prevent it in time and decide what to do the next day."

"Don't underestimate these things, if there is heavy rain or snow that can be predicted, then when there is a major drought, flood, or snow disaster, you can notify the people in advance to prevent it."

"In this way, isn't it a good thing that Daqin can also have some grain and grass left for disaster relief?"

"And in autumn and winter, it can also remind the people to harvest grain and grass in time to avoid frost."

Everyone present nodded and expressed their approval to Ran Fang.

None of them thought about these questions, and even Zou Yixiu was a little surprised, is his yin and yang still so useful?

But after thinking about it, what Ran Fang said was indeed not wrong, they could do it!

"What the commander said is true, and it is true."

"But this is a trivial matter, if you really encounter a big flood, even if you know it in advance, it will only increase people's panic."

"How can we stand up to the heavens?"

This idea was ingrained in everyone's hearts, and Ran Fang didn't think there was anything wrong with him saying this.

It's just that he doesn't agree.

He looked at the people present very firmly and said, "You are wrong, I always think that man will win the day!" ”

"In the face of natural disasters, we may seem powerless, only waiting for death."

"But that's not the case, just like the floods in Surabaya County, you can reduce the damage caused by flooding by building canals to change the direction of the river."

"If we can anticipate floods, we can build a dam that can store some of the floodwater, or we can release some of the water from the river before the flood comes, and then we will be able to receive that rain."

"Isn't that a good idea?"

"If you predict heavy snowfall in advance, you can also prepare more items to protect people from the cold and tell people to go out less so that they can get through, isn't that okay?"

"There are also strong winds and earth dragons turning over, as long as they can be predicted in advance, they can reduce some casualties."

Ran Fang said these words very slowly, and the people present also listened very carefully.

If it was really as Ran Fang said, it would definitely be a good thing for Daqin.

But is the Yin and Yang family really so powerful?

The eyes of everyone present looked at Zou Yixiu.

Zou Yixiu, who was watching, lowered his head a little embarrassed, and said in a heavy voice: "This ......"

"The Yin-Yang family can indeed predict the stars, but it cannot guarantee that it will be accurate and speechless every time."

"Moreover, as the commander said, he predicted the turn of the earth dragon and predicted the wind, these ...... I'm afraid I can't do it. ”

The people present all showed disappointed looks, they really thought they could see the picture that Ran Fang said.

Ran Fang said with a smile: "No one can be accurate, this kind of thing can have a fault tolerance." ”

After all, even the most authoritative weather forecasting department was not so accurate.

He continued: "You may not be able to do it manually, but with some instruments, you can do some of it." ”

"As far as I know, there is a thing called the Geokinetic Instrument, which can predict or know the general direction of the Earth Dragon's turnover, and then it will be able to transfer people in advance?"

"This is the use of observing the heavens, as long as it is used properly, it is a good thing for the people and Daqin."

These few words completely mobilized Zou Yixiu's interest, he had never heard of these things, and he was immersed in the picture that Ran Fang said for a while.

Gu Siyuan, who was very interested in listening, listened to Ran Fang's words, and couldn't wait to ask, "What about the palm geography?" ”

"What is this?"

Ran Fang thought for a moment before he spoke: "To be in charge of geography is to grasp the mineral resources that Scorpio loves and know the general trend of the world. ”

"In particular, some resources that are conducive to the development of Daqin, such as iron ore, coal mines, copper mines, and undiscovered salt pan salt ponds, are all related to the lifeblood of Daqin."

"If the Yin and Yang Family can do this, will they still worry that the Yin and Yang Family will not be able to enter His Majesty's eyes, and there will be people who will not accept it?"

In the last sentence, Ran Fang looked at Zou Yixiu and said it, as if he was waiting for his answer.

That Zou Yixiu also lived up to expectations, with a strong interest in his eyes, and seemed to have an inexplicable reverence for Ran Fang when he said this.

If it is true, then this Yin and Yang family will stand firmly in the hundred schools, and there is no need to worry that there will be people who are unwilling to learn.

"Sir, you just said that there is a seismograph for observing the turning of the earth dragon, but I have never heard of this."

"And the observation of the heavens, the grasp of geography, I don't know what these things need."

"Please sir."

It was completely different from the reaction he had just heard Ran Fang say that he could watch the moon, and Zou Yixiu's attitude at this time was very sincere.

Ran Fang didn't embarrass him, and said generously: "It's very simple, there are windmills and anemometers to measure wind speed, and there are armillary spheres to observe celestial phenomena." ”

Even if he didn't understand what these were, Zou Yixiu still nodded first.

Then, he asked a little embarrassed, "What about that...... What about those who look at the moon? ”
