Looking at Li Tai's posture, I am afraid that he will not turn back if he does not hit the south wall, Li Zexuan has no choice but to be an adult, so that he will hit his head and bleed.

"Your Highness, please listen to the fifth question, before asking, I want to know if Your Highness has ever heard of "Mulan Ci"?"

Li Tai nodded: "Of course I heard it." ”

Mulan Ci, also known as Mulan Poem, is a narrative poem during the Northern and Southern Dynasties of China, telling the folk tale of the heroine Hua Mulan serving in the army on behalf of her father. The poem was written in the Northern Wei Dynasty, and was originally recorded in the Southern Dynasty Chen's "Ancient and Modern Music Records", which is more than 300 words long, and was later polished by the literati of the Sui and Tang dynasties.

Li Tai is well-read, and of course he has read this poem.

"Your Highness has heard it, the fifth question is that after Hua Mulan, who has been in the army for 18 years, changed into women's clothes, why did she surprise her former robe?"

Lee Tae replied as a matter of course: "Isn't it surprised that her companion has never seen her wear women's clothes?" ”

Li Zexuan shook his head: "Wrong, that's because her comrades think it's more appropriate for her to wear men's clothes." ”

Li Tai: .......

He really has a sentence in his heart at the moment, and he doesn't know whether to talk about it or not.

"Poof, hahaha. Sizzle~~" Cheng Chumo couldn't stand it anymore, laughed, and tragically pulled the wound on his face.

Lan'er also covered her mouth when she heard this funny answer, and couldn't help but "giggle" and laugh.

Li Tai said with a dark face: "Go on, next question." ”

.......

"Next question."

.......

"Next question."

.......

As time passed, Li Tai's face became darker and darker, but he couldn't help but listen to the next question every time, gambling aside, Li Zexuan's every question was very novel, and the answers to each question were even more unexpected.

He now thinks about a person who is addicted to opium, and although he knows that he will lose if he continues like this, he still can't help but want to hear the next question and the answer to the next question.

"Your Highness, this is the last question, please listen to the question."

After Li Zexuan finished speaking, he was also relieved in his heart, and he was finally going to get rid of this difficult little fat man.

"Wait!"

Hearing that this was the last question, Li Tai was shocked in his heart, and hurriedly interrupted, he frowned, thought about it and said:

"Last question, you are not allowed to make this kind of crooked and evil topic again, you must come up with a serious topic."

If he really can't answer a single question, wouldn't it be discredited, although Li Tai likes the bizarre questions before, it doesn't mean that he is willing to lose the gamble.

Li Zexuan looked at Li Tai's black face, and he didn't want to force this little fat man to be anxious, so he thought about it and said:

"I heard that His Highness is also proficient in arithmetic, so how about I come up with an arithmetic problem for this last question?"

Hey, since this little fat man is looking for abuse by himself, then it's no wonder to me, serious topics can also play you to death, Li Zexuan thought sinisterly in his heart.

Li Tai came to the spirit, and he was still quite confident in arithmetic, he didn't believe that Li Zexuan could stump him.

"Okay, it's a problem, you can solve the problem quickly!"

"Then Your Highness, please listen to the tenth question, suppose that my Tang Dynasty wants to use troops against the Turks, and I need to mobilize 100,000 quintals of grain and grass from Qinzhou and transport them to the front line of Fengzhou, and take the waterway, for every hundred miles, 300 quintals of grain and grass will be lost, and by land, for every hundred miles, 500 quintals of grain and grass will be lost."

"If the army transporting grain has traveled a total of 1,000 miles by water and land, and finally there are 95,800 quintals of grain and grass left, may I ask Your Highness, how many miles this team of grain transporting soldiers has traveled by water and land."

Li Zexuan casually made up a binary equation application problem, as for the higher-order equations, forget it, he was afraid that Li Tai would not be able to understand it.

Although this question is not as strange as before, it is still difficult for the ancients, and the people of the Tang Dynasty did not have the concept of equations.

Li Tai frowned, this question is dignified, he tested all the hypothetical possibilities one by one in his heart, and gradually, sweat broke out on his forehead, and after a long time, he still did not try the correct answer.

Li Zexuan reminded at this time: "Your Highness, the East Market will be closed in a while. ”

Li Tai looked at the sky and said unwillingly: "If there is another hour, this king will definitely be able to solve the correct answer." ”

Li Zexuan said with a smile: "Your Highness, the correct answer to this question is four hundred miles by water and six hundred miles by land. ”

Li Tai subconsciously substituted the answer given by Li Zexuan into the question and found that it was correct, but he still didn't believe it:

"You must have figured out the answer in advance, so you can say it so quickly now."

"If Your Highness doesn't believe it, you can change a few numbers in this question at will to see if I can calculate the three breaths, if I can't calculate it, today's gamble will be counted as my loss."

"Okay, that's what you said. The king changed the last surplus grain and grass into 96,500 quintals, and you can calculate how many miles each traveled by water and land. ”

Li Tai changed a data at will, and he didn't believe that Li Zexuan could calculate the answer within three breaths.

Li Zexuan's current mental strength is far beyond the reach of people, and as soon as Li Tai finished speaking, he immediately came up with an answer in his mind.

"Your Highness, the soldier has traveled seven hundred and fifty miles by water and two hundred and fifty miles by land."

So fast! It was less than a breath, Li Tai was extremely shocked in his heart, and hurriedly substituted the answer given by Li Zexuan into the question, and after a while, Li Tai's eyes widened and he muttered: "It's completely correct, how is this possible, and it is impossible for Dr. Liu of Guozijian to do it......"

Although Cheng Chumo didn't know how to learn, seeing Li Tai's reaction at this time, he also knew that his good brother was right, so he couldn't help but refresh his cognition of Li Zexuan again, and thought in his heart: Even if your kung fu is better than me, why are you still smarter than me, how can I live in the future.

Lan'er was not worried at all when Li Tai was going to compare with Li Zexuan, and she still remembered Li Zexuan's brave performance in the ready-to-wear shop before.

"Your Highness, what about our gamble today?"

Looking at Li Tai, who was a little distracted, Li Zexuan asked with some concern.

Li Tai was really abused today, he waved his hand a little dejectedly and said:

"I am willing to lose the bet, and this king will not come to embarrass your Quirk Pavilion in the future."

"Thank you, Your Highness, for keeping your word, then we will leave."

Li Zexuan still has some appreciation for the quality of this little fat man who is willing to gamble and lose and keep his promises.

"Wait, are you really unwilling to write a story for this king? If you have any requests, the king will consider them at his discretion. ”

Li Tai was still a little reluctant, but his tone at the moment was no longer as arrogant as it was at the beginning. The person in front of him is not only a wonderfully written story, but also quite talented, with strange ideas, he is a smart and interesting person, Li Tai really wants to attract him to the palace as a guest.

Li Zexuan shook his head: "I'm sorry, Xiaomin is really not here." ”

Looking at the disappointed look of the little fat man in front of him, he also felt that Li Tai's tone at this time was not as arrogant as before, and secretly said in his heart that this fat man was just a child spoiled by his parents.

Li Zexuan then added: "But in my spare time, I will also write some stories, and when the time comes, I will engrave them into a book and sell them in the Wonder Pavilion." ”

Li Tai's eyes lit up, and he said with a smile: "Okay, when the time comes, this king will definitely let people buy a few copies." But you are a master of arithmetic, you must tell this king another day, and I will definitely not treat you badly. ”

Li Zexuan smiled: "Of course you can." ”

.......

Several people said goodbye and separated, Li Zexuan looked at the sky, it was estimated that there would be a quarter of an hour before Fang City would close, so he asked Wang Zhong to take Lan'er back first, and he walked quickly to the Qiqu Pavilion Workshop, and happened to meet Fu Bo who was about to go home.

After asking about the progress of Fu Bo's qu yuan plow, Fu Bo smiled:

"Young master, the twenty zigzag ploughs you want have all been made, just wait for you to have someone come and pull them away tomorrow. The old man will go to Zhuangzi with the young master tomorrow to see how the quyuan plow works. ”

Li Zexuan nodded: "Well, that's good, I'll have someone pull these quyuan plows away tomorrow." ”

At this time, Fauber seemed to suddenly think of something, and said: "Oh, by the way, young master, the roller bearing you proposed before has been made in the workshop, and now we can make roller bearings of various specifications." ”

Li Zexuan was overjoyed when he heard this, and said with a smile: "Great, then after this busy time, I will give Fu Bo a drawing, and Fu Bo will help me build a carriage, and all the parts that need to be rotated will be equipped with roller bearings." ”

The luxury carriage he had been thinking about for a long time finally had hope, and Li Zexuan was very happy in his heart.

Fauber smiled, "Okay, no problem. ”
