Farmer of Shu Han

It's just that Feng Yong felt that if the old man Wei's defeat was included in Zhuge's calculations, it would be a little too suspicious of the character of the prime minister.

However, if Hao Zhao hadn't been paralyzed by the defeat, the subsequent action of digging ditches and building fortifications might not have been carried out smoothly.

so……

Feng Yong glanced at Zhuge Liang secretly, feeling a little entangled in his heart, which situation is the truth? Do I want to think of the great Han prime minister as brighter or darker?

Feng Tubie was still swaying, but he didn't expect Jiang Wei to think much more than he dared to think, "Did the Prime Minister already calculate the battle with Hao Zhao at the beginning?"

"The prime minister let Hao Zhao escape easily, in fact, to convince Hao Zhao that there is no way for a big man to catch up with him, so he guards the city so reassuringly."

When Feng Yong heard this, he couldn't help raising his brows, and looked at Jiang Wei: You are so generous, boy, you dare to imagine more than I do.

According to this, maybe the old monster Zhuge didn't take Guan Xing to Xiangwu immediately, but put him in Linwei, so he already started counting? Just enough to hide one's own mobility.

When Zhuge Liang heard Jiang Wei's words, he smiled indifferently, "Soldiers are impermanent, and water is impermanent. How can there be any secret and leak-free strategy in this world?"

"You can only constantly modify and adjust your strategy according to the actual situation in front of you, and try to let the enemy make arrangements without noticing it."

Feng Yong strained his ears to listen, but the prime minister did not say what he most wanted to hear: You haven't said whether those two battles are in your plan or not!

Seeing that Zhuge Liang stopped talking and did not continue, Feng Yongda was disappointed.

He thought for a while, and then asked again, "Prime Minister, I think the water in the Wei River is decreasing, but it will probably take half a month before it stops flowing. What if it rains in this half month?" manage?"

"That's exactly what I'm worried about," Zhuge Liang looked up at the sky again, "Although according to the current situation, it is very likely that the severe drought will continue, but if there is a sudden rain and the Weishui River rises, I'm afraid it will be a disaster." This gave Hao Zhao a chance to escape."

As he spoke, he sighed again, "That's why I said, how can there be any secret plan in this world? It just depends on whether the opportunity is great or not. These days I come to see the Weishui every day, just to estimate when it will be possible. Stop the flow on top in advance."

"If you can cut off the water one day in advance, you will have a chance for one day. As long as you cut off the water for three to five days, the water in the well in the city will start to decrease."

"It's just that when and where the Weishui should be cut off, and how wide and deep the ditches should be dug. This is also one of the advantages of the location, but it needs to be carefully estimated."

Feng Yong heard this, thought for a while, walked to the water's edge, gestured, and turned around, "If the prime minister wants to know when to stop the flow, I have a way."

As soon as these words came out, not only Zhuge Liang, but also Jiang Wei cast their gazes over.

"Prime Minister, instead of coming here every day and standing on the shore to estimate, it is better to go directly into the water and measure the water flow. Measure it today and measure it tomorrow, and compare the two."

"First, we can calculate when the Wei River will stop flowing, and second, we can find low-lying places above based on the measured water volume, and open canals to drain the water in advance."

Hao Zhao in the city is not a fool. If he waits for the Weishui to dry up naturally, he will definitely make arrangements before the Weishui runs dry, so he must stop the flow in advance.

"Measuring water?"

As soon as these words came out, not to mention Jiang Wei, even Zhuge Liang felt a little inconceivable, "This water has an impermanent form, who can figure it out?"

Feng Tubie pointed to himself, and said with a smile, "I can count!"

As long as the cross-sectional area of ​​the river is calculated and its flow velocity is measured, its flow rate can be roughly calculated.

Basic knowledge of geography.

It's not a big river, but it's not easy to calculate the amount of water in the Weishui River?

It's not about doing a century-old project, just make a rough estimate, and then add some water... Cough, cross this out, and get used to it.

Well, as long as there is a general result, that is, a five-day project, as long as there are enough people, digging canals and drainage can be done casually.

If time permits, Feng Yong can even calculate how many depressions are needed to accommodate the total water volume for the five days.

But it's not necessary. As long as the drought continues, the water flow will only get smaller and smaller. As long as it is confirmed that there will be no backflow within five days, the engineering team can directly excavate, and there is no quality supervision. What are you afraid of?

In the face of great mathematical tools, this so-called geographical advantage is nothing to worry about.

This time, not only Jiang Wei opened his mouth wide and stared blankly at Feng Yong, but even the Prime Minister of the Han Dynasty looked at him in horror, and said in a voiceless voice, "You can do this?"

"I understand a little."

Feng Senior Intellectual Yong shook his head, triumphantly.

You illiterates in feudal society, how can you understand the power of my Great Scientology?

In this case, if the amount of water can be calculated more accurately, the date for arranging closure can be accurately set.

Even if it is one day earlier, that is still a day's advantage. If there is a day's difference, and it suddenly rains in the sky, then it will be called wanting to cry without tears.

"Forget this, is it troublesome?" The pragmatic prime minister didn't bother about this too much, and asked impatiently.

"No trouble, as long as you find a gentle river section, you can calculate it in half a day."

"Okay!" Zhuge Liang was overjoyed, "How much equipment do you need?"

"No, I just need a few tents in the engineering team."

"Okay, okay!" Zhuge Liang's eyes burst into brilliance, he really didn't expect Feng Yong to have such abilities, he was surprised and delighted, "This is to control the gods and measure impermanence!"

Just do it.

The river section that is convenient for measurement is easy to find, and the cross section is also easy to measure, but the flow rate is a bit troublesome because there is no stopwatch for timing.

But this doesn't matter, there is no stopwatch, then follow the timing method of this era, use the clepsydra to repeat the calculation many times, and then take the average.

Anyway, it's just a matter of continuous sampling in the river section that is convenient for measurement, and repeated calculations, it's no big deal.

Jiang Wei was still in the mood to see how Feng Yong calculated, but when he saw Feng Yong drew something like a ghost on the notebook, he was secretly shocked: I heard from the prime minister that Feng Langjun came out of the mountain gate. , it seems true.

Just looking at this symbol that is different from the world's words, or his master has existed since ancient times, and this is a long-lost secret text.

Or it is a text developed by several generations of people, which is specially used to record the knowledge of teachers, for fear of leaking this ghostly knowledge.

Feng Yong stood up again after counting halfway, and yelled at the people in the river, "The next section of the river."

Then he threw away the notebook, and while they started measuring again, the cat leaned over to look for something on the ground.

Jiang Wei walked over and asked softly, "What is General Feng looking for? Maybe Wei can help?"

"Oh, it's nothing, just like this wild vegetable, have you seen it? If General Jiang is free, you might as well help me find it and pull up a few more."

Feng Yong lowered his head and was earnestly pulling weeds.

Jiang Wei wanted to get closer to Feng Yong, so he also went down immediately, pulling the grass in his hands, and asked, "Is there something special about this kind of grass?"

"It's nothing special, it's just that it's too hot and I want to eat some green vegetables. This can be eaten as a vegetable."

Feng Yong answered seriously.

Jiang Wei's hands paused, and he hesitated, "General Feng, this, aren't we measuring the Wei River now?"

"That Wenshi should be able to remember the process. Let him list the data for me first, and then I will calculate the data at the end."

Seeing a fat noodle tree, his face was overjoyed, and he quickly dug it out carefully, and at the same time replied casually.

Jiang Wei shook his hand again when he heard this, "How could the general give such knowledge lightly to others?"

Feng Yong let out a long sigh when he heard this, and said depressedly, "It would be great if he could really learn it!"

In terms of learning ability, Amei is the one who satisfied Feng Yong the most. According to her learning progress before she left Yuejuan, she should have completed half of the high school content by herself.

But even if Amei was to do the math, it would be too much.
