Zhang Huan found that Shen Kuo was really different from ordinary bureaucrats, if a military and political official like him really attached so much importance to abacus, he would have to ask Zhang Huan in the future, instead of asking him face to face now, which can only mean one thing, this person, who was called a great scientist by later generations, was very curious about new things and new objects, and even shamelessly asked for it, even if the other side was just an ordinary poor man, he didn't care about asking in person.

It is indeed the first person in ancient Chinese science and technology, but at this time, Shen Kuo has not yet lived in seclusion in the dream manor and wrote the all-encompassing book Mengxi Pen Talk that established his supreme position.

At this time, Shen Kuo still put his, well, official position and main business first, after all, he has been on the rise for more than ten years, and as for those side jobs of writing books, he doesn't have so much leisure time, but his innate strong desire for knowledge makes him have to figure out a lot of things.

"Shen Xianggong, a certain one is called an abacus, this thing can replace the abacus, and it is estimated that it can be several times faster,"

Zhang Environmental Protection guarded a little, because he hadn't tried it, in the end, it was a lot, in short, it was soon.

"Oh, abacus, what a good thing,"

Shen Kuo nodded, several times, more than that, he is an expert in calculations, and it is possible to improve ten times according to what he sees, but can this last abacus replace all the calculations, you must know that the calculations can be added, subtracted, multiplied and divided by decimal negative numbers, I don't know if this small abacus is possible.

"My lord, I've been trying it out for a few days in Yanxi Academy, and it's really fast,"

Liu Yue said with a smile.

"Well, okay, the day after tomorrow, Liu Shanchang will take Zhang Huan to the Economic Strategy Division and his party, and talk about this abacus for the official."

Shen Kuo nodded.

Liu Yue was overjoyed, Shen Xianggong invited their teachers and students to the Jingluo Division and his party, what a big face, abacus has the recommendation of the Jingluo appeasement to make the adult, and Yanxi School is also famous.

"Congratulations to Mr. Liu, this is a blockbuster,"

Tang Xueyi arched his hand with a smile.

"Where, where, the top few students in the school are all state students, I am ashamed of myself in Yanxi School, congratulations to Professor Tang,"

Liu Yue hurriedly returned the salute, he didn't dare to trust it, Tang Xueyi was a person with official status.

"It is important to know that the way of calculation is an important knowledge in the eyes of Shen Xianggong, and Mr. Liu must not be humble,"

Tang Xueyi smiled, well, don't pretend to be confused.

Shen Kuo's preference for calculations, astronomical calendars and other objects is famous, so the officials and gentry in Yanzhou basically know that Shangguan's preferences must be clear.

Liu Yue hurriedly smiled and said that he didn't dare to dare, he didn't want to step into the officialdom because of Shen Kuo's favor, he knew that he couldn't go that way, and his mind was now on Yanxi Academy.

After the school examination ended, the crowd around the martial arts arena dispersed, and Shen Kuo held a banquet to entertain the professors and gentlemen of the State School and Yanxi School, as well as the top few students, of course, all this had nothing to do with Zhang Huan.

Although Zhang Huan shined in planning and archery, he was inferior to Sun Shan in other examination schools, and he was not qualified to attend the banquet.

The only good thing is that Zhang Huan took the black cloud back on the way, and pointed him out from time to time, which was finally a blockbuster, and some people knew about Zhang Huan of Yanxi Academy in the future.

Zhang Huan returned home, Chen and Zhang Hao at home did not know Zhang Huan's amazing performance, and guessed according to their previous results, Chen and Zhang Hao did not ask at all.

Why, the results are quite dismal, didn't asking Zhang Huan rub the fire in his heart, so no one asked about the tacit understanding between the mother and son.

And Zhang Yuan didn't know anything about it.

"Childe is hard."

Because she has been with the Chen family for a long time, Qiu Tao also knew that Zhang Huan in the past was a person who could not learn, so she just asked for peace and never mentioned the school examination.

This made Zhang Huan a little depressed, his grades still failed, but after all, what is the attitude of the family when he participated in the examination school.

Even Qiu Tao, the so-called maidservant, is the same, tsk, this ring has been weak enough in the past.

Qiu Tao lit a fire to boil water for Zhang Huan, Zhang Huan poured water by himself, did not let Qiu Tao bear the weight, after the water was done, Zhang Huan went in to take a bath by himself, and did not let Qiu Tao serve at all, Qiu Tao is also familiar with Zhang Huan as a person, and there is nothing uncomfortable.

After Zhang Huan washed,

"Qiu Tao, go and call the black tiger,"

Qiu Tao immediately went to bring the black tiger, every time Zhang Huan bathed the black tiger after bathing to wash the black tiger has become a routine, Qiu Tao has never seen such a willing to bathe the dog, of course, now she is not surprised.

The black tiger has been reluctant to accept it from the beginning of his life to the present, and he was suppressed if he didn't accept it, or, from it.

In the evening, Zhang Yuanzhou returned home,

"San Lang, I heard that you have excelled in the examination school in the past two days, and even Shen Xianggong was shocked, but there is such a thing."

Zhang Yuanzhou's face was ruddy, and his eyes were firmly fixed on Zhang Huan.

As soon as these words came out, Chen and Zhang Haohu looked at Zhang Yuanzhou suspiciously, and said in their hearts whether the master remembered something wrong, otherwise how could there be such a statement.

"My nephew's grades are still as bad as before, but he has taken the lead in planning and archery, and Shen Xianggong may be quite interested in my abacus, so let me go to the yamen in the next few days,"

Zhang Huan smiled, well, finally someone in the family knows that he has a small outburst, which is good.

"Hey, there's something like that,"

Zhang Yuanzhou's eyes widened,

Chen Shi and Zhang Hao hurriedly asked, Zhang Yuanzhou explained a few words, the state capital's arrest is also a member of the Yaqian, Mr. Liu Ziyu, one of their staff members who managed them today, returned to the Yamen after attending the banquet, and said a few words How amazing is the calculation of a student of Zhang Huan in Yanxi Academy, and his archery skills are unparalleled, and even Lord Shen Kuo mentioned a few more words at the banquet.

Zhang Yuanzhou asked a few words after listening to it, to see if it was his nephew, if it wasn't for the unparalleled archery, Zhang Yuanzhou really didn't dare to ask more, he was just a fast catcher who didn't enter the stream, and Mr. Liu was a little far away, and he was very in awe on weekdays.

Mr. Liu is Shen Xianggong's close confidant, and he takes care of the general affairs in the yamen for him on weekdays, although he is only a nine-rank official, but it is not something he can get close to.

When Zhang Yuanzhou confirmed that it was his nephew, Liu Ziyu also smiled and chatted with him, although he was drunk, he might have forgotten about it when he woke up, but the other old officials saw it, Zhang Yuanzhou's life in Yamen in the future would be much better, he never expected that this was brought by his chaotic nephew.

When he got home, he immediately asked Zhang Huan, and sure enough, it was his nephew.

Zhang Yuanzhou explained to his wife and children, and said with emotion,

"San Lang is older, I don't have to worry about it."

Laughing heartily.

At this time, Chen and Zhang Hao looked at Zhang Huan very differently.

"It would be nice if my family Hao'er could have Saburo's ability in the future,"

Chan sighed.

Zhang Yuanzhou glared at her,

"Then send it to Shunning Village, where San Lang's magic arrow was practiced."

"Well, that's not going to work,。。"

As soon as Chen heard this, he didn't say anything anymore, what kind of difficult realm is Shunning Village.

Qiu Tao, who served the food back and forth, didn't know much about it, but she also knew that Zhang Huan was in the limelight in today's examination school, is this true?

So when eating, Qiu Tao, who was alone on the small table, kept looking at Zhang Huan with her eyes.

People have vanity, and Zhang Huan is no exception, making a beautiful girl look at it as if it's good.

However, if there is always someone watching, it feels like being watched for a long time.

"I don't have any rice on my face, do you always look at something,"

When he returned to his yard, Zhang Huan said speechlessly.

"I think my son-in-law is so outstanding, he will definitely be able to roll call Donghuamen in the future,"

Qiu Tao said with great longing.

Snort, Zhang Huan was taken aback, do you know how difficult it is for Donghuamen to roll call, Qiu Tao really dares to think about it.

"Alas, if I can't, wouldn't you look down on me,"

"Hmm,"

Qiu Tao nodded, and immediately knew that something was wrong, and hurriedly covered her mouth and smiled,

"No, the maid said it was smooth, hehe,"

Qiu Tao has been with him for a long time, and there are more and more so-called rules.
