After a full meal, everyone ate and fed, half-lying on their chairs, with their hands on their stomachs.

"Thank you Lord for your hospitality, this is the most delicious meal the old man has ever eaten."

Lu Zheng stroked his beard and smiled, compared to just now, he had let go a lot.

Li Changan knew the importance of the wine table culture in his previous life, and after a meal, he toasted and touted, and quickly narrowed the relationship between them.

"Dean Lu, Boss Liu, I don't know if the two of you have considered developing in another place?"

"Somewhere else?"

Lu Zheng and Liu Qingfeng were both stunned, and looked at Li Changan suspiciously.

Liu Qingfeng shook his head and said, "The city lord is joking, the county town is a rich place, and the status is only below the royal city, where else can we change to?" ”

"Don't hide it from you, my border city is vigorously engaged in development, of which education is the most important part, so I want to invite you two to join." Li Changan directly and frankly invited.

Lu Zheng felt a little shocked and asked, "The City Lord is going to open an academy here?" ”

Li Changan nodded, "That's right, the border city is remote, the environment is desolate, most people have never been educated, but I can feel the determination of the people here to thirst for knowledge, there are also children here, we have the ability to give them the opportunity to be educated!" Let the fire of education burn in every corner of the Daying Dynasty, I think Dean Lu must be willing to become the first fire in the border city and light it here. ”

He said this in a high-sounding manner, and he also brought a high hat to Lu Zheng, just to pull him into the water, as a city lord, he had to fool back and coax to develop the local area better.

"Hehe, the old man is old, and he can't withstand this toss."

Lu Zheng looked at Li Chang'an, calmly refused, and then said: "But the city lord has this determination, this is the blessing of the people of the border city, you are a good city lord, after I go back, I will definitely explain this matter to the students of the academy, and call on the people of insight among them to come to this border city to benefit the people!" ”

Damn, cunning old man!

Li Changan was speechless for a moment.

Lu Zheng's reason for refusal was not only perfect, but also offered to call Li Changan to volunteer, which blocked all Li Changan's roads and made him unable to invite again.

To put it bluntly, this old guy simply doesn't want to come to the border city, and also, after all, he is the dean of Bailu Academy, how can he deign to come to the border city?

Da Ru is really not good at fooling.

He looked at Liu Qingfeng again and said, "Boss Liu, our border city is also going to open a bookstore, I wonder if you are interested in coming over to manage it?" ”

"The city lord thinks too highly of me, I even run the White Deer Bookstore in a hurry, where can I get out of the way." Liu Qingfeng coughed lightly and also refused.

These two ......

It's not like this when you eat and drink, why do you put down the dishes and chopsticks and change your face?

Isn't this meal in vain?

Li Changan's brows furrowed slightly.

"The talent of the city lord makes the old man admire, and the heart of the people makes the old man even more ashamed, the royal family has you is a big win, but the construction of the city is not an overnight thing, I hope the city lord is down-to-earth, the old man looks forward to seeing a prosperous border city one day, well, the time is not early, we should also say goodbye."

Lu Zheng said a no-nutritious word, and the meaning of the words was faintly a little bit of a knock on Li Changan, and then he was about to pat his ass and leave.

Li Changan couldn't make sense when he saw that he was kind and pleased, so he could only change his routine, and said coldly: "The city lord originally wanted to give Dean Lu a chance to become the first division in the world, but you couldn't grasp it, since this is the case, then you can go, don't say that the city lord didn't give you a chance in the future." ”

Lu Zheng's figure suddenly stopped, and a lot of anger surged in his heart.

Bai Yaoyao, An Zhaoran and the others also looked at Li Changan in surprise, not understanding why he suddenly changed his attitude and said such things.

"The first division in the world? Hehe, the city lord really dares to think that this title can't be sealed with your mouth! I admit that you are a good writer, but when it comes to teaching students, you are still far behind! Lu Zheng frowned and looked at Li Changan, his tone displeased.

As a contemporary Confucian, he naturally attaches great importance to his reputation, and in his eyes, Li Changan's words just now are already a little humiliating!

Li Changan said: "I dare to say, I naturally have confidence, I don't know if Dean Lu can teach arithmetic?" ”

"As the dean, the old man naturally teaches arithmetic, and now there are several people who are serving in the court, engaged in calculating the water level, distributing food for disaster relief, building bridges and roads, etc., and they can be regarded as making good use of arithmetic."

Lu Zheng spoke modestly, but it was not difficult to hear the pride in his words.

Li Changan said again: "Then Dean Lu is willing to compare arithmetic with me?" ”

"Yes, if the city lord loses, don't blame the old man for bullying the young." Lu Zheng is not a competitive person, but he wants to teach Li Changan a lesson.

"Xiaohe, go and call Zhang Mingda, Zhao Ancheng and Wang Defa over."

Li Changan instructed that Zhang Mingda and they have some arithmetic skills, and they can be a witness, and they can learn a little arithmetic skills in the future to better help Li Changan do things.

Soon, Zhang Mingda and the others came, and they heard that the city lord was going to test arithmetic with Lu Zheng, so they brought their own guys as well, which is the arithmetic of this world!

The so-called arithmetic chips are actually small sticks of the same length and thickness, generally 13-14cm in length, 0.2-0.3cm in diameter, mostly made of bamboo, and are used as tools for arithmetic.

In addition to the abacus, the abacus is also a common arithmetic prop.

Lu Zheng glanced at Zhang Mingda and the others, and didn't take it to heart, he thought that this was the reinforcement called by Li Changan, but even if there were many people, he was not afraid, arithmetic did not rely on the number of people.

Everyone sat down and placed the calculation chips in front of them, all with serious faces, looking ready to start the calculation at any time.

"Isn't the lord himself involved?"

Seeing that Li Changan's front was empty, Lu Zheng couldn't help but ask.

Li Changan smiled slightly, "I don't need to do arithmetic, I rely on mental arithmetic." ”

Mental arithmetic?

This word is the first time everyone has heard it, and it has always been only memorable, but there has never been a person who can do arithmetic by heart!

Li Changan ignored everyone's suspicious gaze and said directly: "For the sake of fairness, let's each come up with a question, and compare who will calculate the result first." ”

"I'll start with the first question."

"A pot of wine can pour 25 glasses, and now there are four people, how many glasses can each drink?"

As soon as this question came out, Lu Zheng and the others began to fiddle with the calculations in front of them.

Li Changan watched with interest, he deliberately waited for a moment, then yawned and said, "The answer is that each person can drink six glasses of wine, and there is one glass of wine left." ”
