Chapter 637 Measurements

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

  However, without that defeat to paralyze Hao Zhao, the subsequent action of digging ditches and building fortifications may not be carried out smoothly.

so…

  Feng Yong glanced at Zhuge Liang secretly, feeling a little tangled 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."

  Feng Yong couldn't help raising his eyebrows when he heard this, and looked at Jiang Wei: Kuo Yi, boy, you dare to imagine more than I do.

  Based on 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.

   Zhuge Liang smiled lightly when he heard Jiang Wei's words, "Soldiers are impermanent, and water is impermanent. How can there be any secret and leaky 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 listened attentively, 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 of 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 Wei River should be cut off, and how wide and deep the ditches should be dug. This is also one of the geographical advantages, 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 also 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 is impermanent, 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 then its flow velocity is measured, its flow rate can be roughly calculated.

   Fundamentals of geography.

   It’s not a big river. It’s not easy to calculate the amount of water in the Weishui River?

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

   Well, as long as there is an approximate 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 is 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?"

   "Slightly understand."

  Feng Senior Intellectuals always shook their heads, triumphantly.

  You illiterate feudal society, how can you understand the power of our Great Scientology?

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

  Even if it is one day earlier, it is still a day's advantage. If there is a day's difference, and it suddenly rains from the sky, 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 account rooms 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 what you say.

  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, so follow the timing method of this era, use a clepsydra to repeat the calculation many times, and then take the average.

  Anyway, it’s just continuous sampling in the river section that is convenient for measurement, and repeated calculations are not a 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 text, or his sect has existed since ancient times, and this is a long-lost secret text.

  Either 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 threw the book away, 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 look for it for me and pull a few more."

  Feng Yong lowered his head and was earnestly pulling weeds.

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

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

  Feng Yong answered seriously.

  Jiang Wei paused his hands, and said hesitantly, "General Feng, this, aren't we measuring the Wei River now?"

   "The writer 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, he was overjoyed, and quickly dug it out carefully, and at the same time replied casually.

  Jiang Wei trembled his hand again when he heard this, "How could the general teach this kind of knowledge lightly?"

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

   As far as learning ability is concerned, Feng Yong is the one who is most satisfied with Amei. According to her learning progress before she left Yuexuan, she should have completed half of the high school content by herself.

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