As Ye Qing and the others began to go to Qufu County, Zhu Shijie, who was originally alone with Xiao Zhen, had a beautiful little lady behind him, although he was wearing a coarse cloth shirt and skirt, he could still see that at the age of about sixteen or seventeen, if he changed into a beautiful shirt, he would definitely be able to make his appearance more amazing.

The little lady followed Zhu Shijie all the way, and at this time, Ye Qing also learned from Xiao Zhen that this Zhu Shijie turned out to be a great mathematician, so he was quite appreciated by Zhu Xi and others.

As for the little lady who has been following next to her, it turned out to be a woman who escaped after being sold into the Qinglou because of her father's debts, and when she was being chased and beaten by the bustard and his buddies on the street, she happened to be met by Zhu Shijie, so the father's debt of ten taels of silver was ransomed by the old bustard after Zhu Shijie gave fifty taels of silver.

Today's Xiao Zhen, although he does not have an official position on Shandong East Road, but because he has been following Lu Yanlun to expand Yangzhou and Jinan Mansion in the past two years, he is now quite influential in Shandong East Road.

Therefore, Xiao Zhen had already arranged Ye Qing's residence after arriving in Qufu, and since Ye Qing entered Qufu, he had entered the trap set by the hunters, and there was always cold air behind him.

Zhong Silkworm and Jia Shi were personally called in front of Ye Qing, no matter who the county governor was, in short...... No one is allowed to let in, and they must not be allowed to meet with themselves, lest they be completely involved in the matter of having to repair the Confucian Temple.

Although now, Ye Qing has been calculated by Xiao Zhen into the conspiracy to repair the Confucian Temple, but Ye Qing has not made up his mind for a while, along the way, although he has seen that most of the damaged fields can be cultivated, but he is not very clear, whether the fields that were just devastated by the flood last year can usher in the ideal autumn harvest after spring ploughing, Ye Qing is not sure about this.

So as for whether to repair the Confucian Temple, judging from his current shyness, he didn't want to repair it at all, but now that Xiao Zhen stopped himself in Qufu, and Zhu Xi and others were waiting here to take the initiative to send him to the door, Ye Qing was already a little difficult to ride a tiger now.

Xiao Zhen and Zhu Shijie followed him all the way to the post house they had prepared for him a long time ago, and the two had no intention of leaving.

After inviting the two of them to sit down, Ye Qing had to take the initiative to ask, "Mr. Xiao, don't you look at me like this, are you really afraid that I will run away?" And you, the repair of the Confucian Temple has little to do with you, right? Why should you stay here? ”

Zhu Shijie's face turned a little red again, he looked at Ye Qing a little crampedly, and then looked at Xiao Zhen who was sitting with a smile on the side, his lips moved for a long time, but he still couldn't say a complete sentence.

Xiao Zhen sat on the side and smiled silently, Zhu Shijie was brought by him, and it was also because when he was expanding Yangzhou City, Ye Qing once said a sentence proudly in front of him, that is, he has a calculation method, which is faster and more convenient than calculating chips, and there is no need to bring an abacus at all, or a small stick when using a calculating chip.

And Zhu Shijie can be said to be a teenager who is extremely obsessed with arithmetic, and Xiao Zhen admires him a lot, so in order to keep this young man by his side, he told Zhu Shijie what Ye Qing boasted in front of him at the beginning, and even he didn't believe it, which made Zhu Shijie curious, and he wanted to see the faster calculation method that Xiao Zhen added fuel and vinegar.

It's just that since Zhu Shijie met Ye Qing, especially after knowing Ye Qing's true identity, which turned out to be the envoy of all the Song Dynasty territories in the north, he instantly lost the courage to follow Ye Qing for a long time, and the reason why he still came to Ye Qing's post house at this moment, in addition to not knowing what excuse to leave, was that he was still extremely curious in his heart, but he didn't dare to speak.

Xiao Zhen looked at Zhu Shijie, who was sweating under Ye Qing's gaze, who no longer knew whether he was anxious or scared, smiled bitterly, and said secretly: It is really the shadow of a famous tree, and it can actually suppress this obsessive man who is obsessed with arithmetic in a light and light manner.

He knew that even if Zhu Shijie faced Zhu Xi and some other great Confucians, as long as it was related to arithmetic, Zhu Shijie could talk with great confidence no matter how many times he was in front of him, but after seeing Ye Qing today, even if Ye Qing had always had an easy-going smile, but when Zhu Shijie faced the same easy-going gaze, he didn't know why, his confidence in arithmetic disappeared without a trace, and he didn't dare to ask Ye Qing for advice in person.

After hearing Xiao Zhen's explanation for Zhu Shijie, Ye Qing suddenly realized that the reason why this young man appeared was just to compete with him in calculations.

At this time, the abacus has appeared, but it is not yet the algorithm of later generations, and the abacus is still prevalent in the world, so the calculation method of abacus, although some people will use it, but at this time, because the person who wrote "Arithmetic Enlightenment" has not yet written the abacus method that is basically the same as that of later generations.

Today's calculation, although the so-called mainstream is still to use the calculation chip to calculate, just like when Xiao Zhen was expanding Yangzhou City, when he used a small stick to calculate under the city wall, Ye Qing kept talking cool words on the side, so there is no meaning of the number zero, zero is still replaced by a vacant seat in the calculation, plus Ye Qing is making trouble next to him, Xiao Zhen squatted under the city wall and calculated several times, and calculated different results, and was finally ridiculed by Ye Qing.

"In ...... I'd like to ask an adult for a faster calculation. After listening to Xiao Zhen help him speak, Zhu Shijie hurriedly got up and said to Ye Qing.

Looking at Zhu Shijie's nervous sweat, Ye Qing smiled, he couldn't imagine that the old things of the past were still haunted by Xiao Zhen, and he hated himself until now.

"Mr. Xiao, if I really come up with a quick algorithm, can you be accommodating...... Ye Qing's eyes rolled and he began to bargain with Xiao Zhen.

"Even if you can take it out, you have to approve it before you can do it, otherwise, I'm afraid you will trick me again." Xiao Zhen hurriedly blocked Ye Qing's way to cheat, and then shook her head and said: "As for accommodation, it's really sorry for Lord Ye, among so many literati, I don't have that influence, let alone this matter, I am just a slave who was kidnapped and sent by someone." ”

"You've pushed it all in." Ye Qing didn't care about Xiao Zhen's words, but it scared Zhu Shijie, who had been nervous on the side, into a cold sweat on his forehead.

Xiao Zhen has no affiliation with him, and strictly speaking, Xiao Zhen is still a golden person, if it weren't for his relationship with Lu Yanlun, I'm afraid Xiao Zhen wouldn't be very good at taking care of herself, let alone helping her build the two cities of Yangzhou and Jinan.

"That'...... The students were brave and wanted to compete with Lord Ye ....... Zhu Shijie saluted Ye Qing again.

After such a while, when Zhu Shijie faced Ye Qing, he actually changed three self-names one after another, first claiming to be small, and then changing his name to Zaixia, and now seeing that Ye Qing had no objection, he instantly called himself a student again, which completely treated Ye Qing as a Confucian like Zhu Xi.

"Forget about the competition, since you often travel all over the world, running for the best answer to the arithmetic in your heart, I won't take the axe. But....... Ye Qing stroked his chin and pondered for a while and said, "I have a suggestion, and I hope you will see if it is feasible." ”

After finishing speaking, regardless of whether Zhu Shijie was willing or not, he asked Zhong Silkworm to bring a pen and paper, and then wrote out the Arabic numerals from zero to nine.

Zhu Shijie on the side frowned, and Xiao Zhen saw Zhu Shijie frowning, so he immediately came over with interest, could it be that Lord Ye really has this ability? can make this little madman obsessed with arithmetic treat it so solemnly.

Ye Qing didn't make a fool of himself, and without waiting for Zhu Shijie to ask, he began to talk about everything he knew about Arabic numerals, especially when he talked about the number zero, when he understood that in addition to the vacancy in the calculation, his eyes instantly became extraordinarily bright, and then in the quick inquiries again and again, Ye Qing also frankly knew everything and said everything, as for what he didn't know, he also shrugged his shoulders very frankly, saying that he didn't know.

The time unconsciously came to dark, and when Ye Qing looked out of the window impatiently several times, Zhu Shijie still turned a blind eye, completely lacking his previous timidity, observing words and feelings, and tirelessly ignoring Ye Qing's impatience, and had the potential to hollow out the little thing about arithmetic in Ye Qing's stomach.

So it wasn't until Jia She's performance came from outside, and when Zhu Xi and others came to visit, Zhu Shijie raised his head and looked out the window: "Ah, it's so late." ”

Looking at the blank and innocent expression, Ye Qing couldn't wait to kick this little bastard out, but after thinking about the food he had just eaten in his stomach, as well as the tea that Zhu Shijie's maid made for himself, Lord Ye couldn't help but be violent to Zhu Shijie.

As Zhu Xi's footsteps sounded outside, Zhu Shijie, who was stretching, hurriedly looked at the piece on the table, which had already been written and painted by him, I am afraid that even he himself would take a long time to be able to sort out the things smoothly, and then all folded up.

"Your Excellency...... These...... Can these students ...... Can you take them all back and figure it out? Holding the paper in his hand like a ghost drawing, Zhu Shijie asked nervously for fear that Ye Qing would not let him take it away, or for fear of being seen by others.

Ye Qing shrugged his shoulders, patted his stomach and said, "But I warn you, I have already told you everything I know, even if you don't understand anything tomorrow, you can only figure it out and answer it yourself, don't bother me anymore, otherwise it will ......." Ye Qing said with a sneer on the corner of his mouth the moment Zhu Xi walked in: "Otherwise, I will throw you into the prison......." ”

"Don't worry, the student has memorized everything the adults have explained, but they still need to go back and think about it more, and I hope the adults will agree." In Zhu Shijie's eyes, Zhu Xi who didn't walk in at all, just looked at Ye Qing blankly, waiting for someone to nod his head and allow it.

"That's nature, I'm not uncommon with this thing, and it's naturally best to give it the most value to the person who can bring it the most value." Ye Qing smiled, and then looked at Xiao Zhen, who greeted Zhu Xi, and signaled that he could leave with Zhu Shijie.
