The Imperial Palace, the Hall of the Two Rites.

"Your Majesty, King Yue has passed...... The two fought. ”

After the ministers discussed the matter of the new plough, they each received their tasks and left, after which Li Junxian entered the palace and said a word without a beginning or an end.

Li Shimin laughed loudly, he naturally knew that what Li Junxian said, everything was under his control, "Aiqing, do you guess, can Fang Yiai beat Qingque?" ”

He promised Li Tai to worship Fang Yiai's teacher, naturally it is not so simple, it is true to cherish talents, and he also wants to take Li Tai's catty to try Fang Yiai's catty to see how much ability he has.

Li Shimin naturally understands his son's character.

Li Tai is a proud character, how could he allow Fang Yiai's mallet to be his master, I am afraid that he will not be able to sit still in the first place.

Sure enough.

When the news was released, Li Taidang ran over.

But in the main hall, Li Shimin was discussing important matters with the minister, so he naturally wouldn't come over to trouble, so he rushed to Fangjiazhuang angrily.

One is a brilliant prince, and an up-and-coming talent in the world, so naturally he has to fight.

Such a good show, he has already attracted the attention of Baiqi.

"I don't know."

Li Junxian replied with a straight look, and when he saw Li Shimin's displeased eyes, he added: "If it was before, the minister would have guessed that Wang Sheng would have been, but now, the minister really can't guess it." ”

Li Shimin let him go, thinking to himself: "I am also very curious, which of the two can win." ”

……

Fangjiazhuang.

When Fang Yiai raised the issue of water injection and water release, Li Tai scoffed at it, thinking according to common sense, it was really funny and ridiculous.

"Who would be so bored and release water while filling it?"

"Don't care who is so boring, will you answer?" The corners of Fang Yiai's mouth twitched, why bother with the question, who the hell did it in reality.

"What's so hard about that!"

Li Tai said angrily, and then there were words in his mouth, and he began to calculate, and it took a stick of incense for a long time, "It's eight quarters!" Eight quarters can fill the pool, is this king right? ”

"Not bad!"

"Your question is too easy, it's not too difficult."

Fang Yiai nodded, Li Tai immediately floated up, she completely forgot about it, and it took a stick of incense to solve it.

The eighth "equation" in "Nine Chapters of Arithmetic" is to solve the problem of an equation, so it is not surprising that Li Tai solved it.

"Now it's my turn."

Li Tai can't wait, Fang Cai is indeed a little underestimated, this time, I want to give him some color to see, "Please listen to the question......"

"Today there is a wall ten feet thick, and two rats wear each other. Rats are two feet a day, and mice are also one foot. Rats are doubled daily, and mice are doubled daily. Q: When will we meet? How much do you wear? ”

Li Tai's question is a classic arithmetic problem in "Nine Chapters of Arithmetic", but he changed all the data in it.

He was full of confidence and didn't believe that Fang Yiai could give the answer, because this question was made casually, and even he didn't know the answer.

It's just that what he didn't expect was that Fang Yiai gave the answer in a few breaths, "We met at the third hour, when the rat wore 8.42 feet and the mouse wore 1.58 feet, Your Highness didn't know if I was right?" ”

After answering, stared at Li Tai and waited for him to judge the result.

"Uh......"

Li Tai was stunned for a moment, he wanted to say that it was wrong, but he was afraid that after saying it, Fang Yiai would come up with evidence, wouldn't that be a slap in the face.

said that he answered correctly, but he was not convinced in his heart, and he silently calculated in his heart, it was another pillar of incense time......

"Yes, that's right!"

Thinking about the difference in the speed of the two answers, Li Tai's eyes widened in disbelief, "How did you do it?" Answered this question before? ”

"It's a math formula! I'm afraid you said this question casually, how could I have answered it. ”

Fang Yiai took it for granted that he was still light-hearted.

Li Tai couldn't calm down, he has always been very smart, and he is often praised by Mr., but he is so much worse than the mallet of Fang Yiai!

He was a little skeptical about life, "How is that possible?" ”

On the side, Cheng Chumo, Changsun Chong and others were also dumbfounded, and the longer they got along with Fang Yiai, the more they felt that he was unfathomable.

Close relatives married, wrote poems, and watched the plough, but he never thought that he was so proficient in arithmetic......

He seems to know everything and can do anything! is talented and knowledgeable, it seems that it is not enough to describe, and he can be called a genius of the world.

Qiao'er and Xueyun saw that they were obsessed, if they weren't afraid of the identity of the prince, they would have jumped up and clapped their hands.

"It's your turn!"

Li Tai urged Fang Yiai to come up with the question, and he became curious about the topic of Fang Yiai, which also aroused his competitive spirit, and regarded it as a challenge.

"How high is Tarzan?"

It's just that as soon as the question of Fang Yiai came out, Li Tai jumped to his feet with anger, "You don't want to be so cheating, how can I know how tall Mount Tai is!" ”

But he refused to admit defeat, "However, there is a method in the "Island Sutra" written by Liu Wei of the Wei Dynasty, called the 'heavy difference method', which can measure the height of the mountain, but the king has not been to Mount Tai, so it cannot be measured. ”

"Do you know how tall Tarzan is?"

Li Tai immediately asked rhetorically.

"Of course I know, Tarzan is high...... It is 457.2 zhang high. ”

Fang Yiai paused while talking, he originally wanted to pretend to be forced, and almost overturned, and he couldn't underestimate the wisdom of the ancients.

When he read the novel in his last life, he wrote about this problem, so he checked it, but in later generations, the unit is meters, and the units of Datang are rulers and zhangs, so he secretly converted it in his heart.

"None of us know, so it's up to you to say it casually."

"Okay, I'll change the question and ask the simplest one."

Fang Yiai smiled, Lao Tzu is all kinds of disobedience! Thinking of a basic question, he searched around, a little speechless, and instructed a subordinate, "Go and find two stones at random." ”

I thought, damn it, the ancients were too sincere!

The yard was spotlessly cleaned, and not even a single piece of gravel could be found.

Everyone didn't know why, but the next person came back quickly and hugged a bunch of stones, not knowing what the young master wanted.

Fang Yiai picked up two pieces casually, one large and one small, he weighed it in his hand and asked: "Two stones were thrown at the height at the same time, and King Yue felt that one fell to the ground first?" ”

"Naturally, the big ones landed first." Li Tai didn't want to think about it, as a matter of course.

"Naturally, it's big, what is there to say about Fang Er." For other questions, Cheng Chu couldn't interject silently, and he had already suffocated him, and he didn't think he would be wrong about this.

Looking at other people, they have the same thoughts, even Qiao'er and Xueyun think the same.

"Give the teacher the first lesson to you, without practice, you have no right to speak......" Fang Yiai grinned, it was this kind of simplest and most common sense question that defeated him and convinced him.
