Hearing the question asked by Liang Wang Li Su, Wang Xin couldn't help but gasp.

This question, can I say no?

Seeing that he was hesitating, Li Su didn't give him time to react at all, and asked directly: "Wang Yushi, you just answer, yes, or no?" ”

"Yes!"

In the end, Wang Xin had to grit his teeth and answer a yes word.

He really didn't dare to answer no, if you want to say that the Tang Dynasty is not more stable, it will not be more prosperous and powerful, isn't this looking for death?

Hearing Wang Xin's answer, Li Su couldn't help but smile and said: "Since you answered yes, it proves that the dragon qi in Chang'an City has not been destroyed, but has become more vigorous. So what are you impeaching me for? ”

At this time, the civil and military forces of the Manchu Dynasty, seeing that Li Su, the king of Liang, only used one question and a few words, and stumped Wang Xin, and couldn't help but cheer in his heart.

Cheng Biting Jin and a bunch of other old goods gave a thumbs up.

In the past confrontations with these Wenchens, in addition to winning by direct hands, they have never won a single bickering.

This victory is really too much for them.

And Wang Xin said at this time: "King Liang, but when you were digging the canal, did you ever think that this flood would probably destroy all Chang'an City!" ”

In fact, in this regard, Li Shimin is also dissatisfied with Li Su in his heart.

It is for this reason that it is for this reason.

Fortunately for now, the water is only knee-high.

But haven't you ever thought about what if Chang'an City is flooded? What if even the palace is washed away?

When the time comes, where will the majesty of the royal family be?

What are the consequences?

And Li Su, after hearing Wang Xin's question, smiled slightly and said: "Before the canal was opened, this king had already calculated, after the canal was opened, the water would not reach the knees." Because of this, the king ordered his soldiers to dig the canals. ”

Hearing Li Su's words, Wang Xin couldn't help but say angrily: "You lie!" How can you possibly calculate such a large amount of water? You are clearly gambling, you don't pay attention to the people in Chang'an City, even the palace. ”

Hearing this, Li Su couldn't help laughing and said: "At that time, the flow speed of the river was seven zhang and two feet per instant, the depth of the river was one zhang and three feet, and the number of cubic meters passed per second was one hundred and thirty-five. The cross-sectional area of the canal is 5.4, the angle between the river and the channel is 47 degrees, and the amount of water that can pass through the river at each moment is ......"

All kinds of data blurted out from Li Su's mouth, and directly confused all the civil and military officials in the entire hall.

Is it all true? Can the velocity of water really be calculated in this way?

For more than a quarter of an hour, they only heard Li Su gushing out all kinds of data, and the final value was that the water in Chang'an City would never reach his knees.

In the end, Li Su concluded: "In exchange for the lives of tens of thousands of people outside the city with the water that will not reach the knee in Chang'an City, Wang Yushi, you come to tell this king, what choice should you make?" ”

"It's-"

At this time, Wang Xin didn't dare to speak indiscriminately.

The point is, when it comes to arithmetic, he is really not proficient.

Not only him, but even Fang Xuanling, Du Ruhui and the eldest grandson Wuji and other Wenchen were counted together, and even Li Yu couldn't understand the calculation method he just said.

But it always feels so powerful.

If Li Su really calculated it in advance, then their impeachment would not be established.

Seeing that Li Su had passed this level like this, at this time, a household servant couldn't help but say: "King Liang, I am a household servant, proficient in arithmetic. But I've never heard of being able to calculate the values you're talking about through arithmetic, so you're just quibbling. ”

Hearing this waiter's words, Li Su couldn't help but smile and said, "You can't, that's because you're stupid!" How much do you know about arithmetic? ”

This household servant was not annoyed, and said with a slight smile: "Since King Liang is so confident in his arithmetic, then, the lower official wants to ask King Liang, I don't know how long it will take for His Highness to calculate the accounts of my household department for three years?" ”

The household department recently cleaned up the accounts for three years, because the data is huge and the calculation is cumbersome, so the household department has set up a special accounting department, which took half a year, and it has just been calculated recently.

And this time, this household servant is actually giving Li Su a problem.

Although it is the same arithmetic, there is still a difference between settling accounts and simple arithmetic.

This household servant wants to use the problems of their household department to make Li Su uncomfortable.

Hearing the words of this household servant, Li Su smiled and said: "As long as those classmates in the primary school are found, this king believes that half a month is enough." ”

What the?

Just a little time and a half?

Hum!

What a big breath!

Hearing Li Su's words, the household servant couldn't help but be overjoyed, and couldn't help but say: "Okay, if King Liang can really settle the accounts of my household department for three years within half a month, it will prove that His Royal Highness is really amazing in arithmetic, and His Royal Highness has already calculated all this." ”

"Otherwise, it can only show that His Highness simply doesn't care about the lives of the people in Chang'an City! When the time comes, His Highness will inevitably be severely punished! Has Your Highness ever thought about it, and did you really dare to agree to come down? ”

Hearing this, Li Su couldn't help laughing and said, "This is natural. However, if this king can really be calculated within half a month, does that prove that you are framing a prince? And when the time comes, will you also be punished for your sins? ”

"It's-"

"Good! If Your Highness can really calculate it within half a month, we are willing to be punished! ”

Seeing that Li Su agreed so happily, Li Shimin couldn't help but shake his head.

I still feel in my heart that Li Su shouldn't have agreed so quickly.

Now, there is no room for repentance.

……

On the second day, Li Su pulled all the classmates in the elementary school over.

When those students learned that in the next half month, they would help Li Su calculate the accounts of the household department for three years, they were both excited and nervous.

The excitement is that they can do great things too.

The nervous thing is, what if they can't finish it?

Among these classmates, there are also those who don't deal with Li Su, such as Fang Yiai and Chai Lingwu.

But even the two of them didn't think about dragging Li Su back now.

Because, they are reprimanded every day, and they also want to prove themselves.

Then, Li Su stood in front of them, smiled and said, "Actually, calculating the accounts is very simple. Come, next, I'm going to give you a pen each, and you're going to make a table, and then I'm going to fill in the numbers all the numbers in order. Once you've listed everything, you can expand the calculations. ”
