At this time, the study room is very quiet, even if a needle falls on the ground, you can hear it clearly. Jiao Deyou www.biquge.info who was looking at Wang Bian nervously, and then looked at Jia Xian, who was holding his breath and preparing to speak. He knew that he had a great responsibility as a bank manager, and he came in and out so many taels of silver every day, but he couldn't explain to the king if there was a mistake. And Jia Xian, this kid, has been working in the bank for a few days, but he is quite welcome, but this matter of giving advice to the king, not to mention Jia Xian, there is no precedent in the entire palace. This is not to say how strict the king is, but in everyone's opinion, there is no problem that the king can't solve, and there is nothing he can't do.

Wang next to quietly looked at Jia Xian, this young man in his early twenties, is still inconspicuous, but who else besides Wang next to him knows that this young man is the author of books such as "The Yellow Emperor's Nine Chapters of Algorithm and Fine Grass", "Interpretation of Lock Calculation Book" and other books, and created the "Jia Xian Triangle" and "Increase and Multiplication Method". This time predates the method of the European mathematician Horner by more than 700 years.

Jia Xian closed his eyes and calmed down, then bowed to the king and said: "Lord, small understanding, your bank's profit depends on the interest rate difference between the loan and the deposit received, and I always feel that the interest rate difference cannot be inconvenient. Take deposits as an example, now that it is peaceful today, the people have surplus money in abundance, and it is safe to get it with interest in the bank. But if there is a famine, the price of food rises, and the money in the hands of the people is deposited in the bank, and the interest money received is not enough to subsidize the rising part, who will put the money in the bank? ”

When Jiao Deyou heard this, he pursed his lips: "What you said sounds right, but it's all a famine, and the people don't have any money in the bank, even if they don't save it, it may not be enough to buy grain." Does this have anything to do with interest? ”

Wang waved his hand: "Brother Jiao, let him continue first." "Although on weekdays, everyone in and out of the king respectfully calls him the prince, but in private, the king is still commensurate with these brothers around him.

Hearing what the king said, Jia Xian looked at Jiao Deyou with envy, who can call the prince a brother and brother, this is called Jiao's shopkeeper, which is amazing. However, when he saw that the king was beside him and let him continue, he also had more confidence in his heart. Just now he bowed his head, his hand had relaxed and his head was raised, and he looked at the king and nodded lightly, as if he was more encouraged. "Shopkeeper Jiao, you are right, people can't buy grain when they encounter a food shortage, and most of the grain is hoarded by large households, why do they hoard, it is because hoarding grain can make enough money. However, although the prince opened the bank to face the people, it is the big households that can really make the bank profitable, that is, the money of these rich gentry. Let's put it this way, the price of rice in the Qingli period was only seventy or eighty wen a bucket, and in the second year of Huangyou, the price of rice was one hundred and twenty wen a bucket. If I have 100 yuan and could have bought more than a bucket of rice, but after a few years in the bank, I can't even buy a bucket of rice, then what else do I keep the money in the bank? ”

"Well, that's a good point, go ahead!" Wang Jian listened to what the young man said well, after all, he was a person who returned to the Song Dynasty from modern times, although he knew a lot about historical events with his thousand-year-old experience and information about wearing ancient stones, but Wang Jian knew very little about the people.

"No, if you buy a bucket of rice and leave it for six years, if you don't eat it, the worms will go bad." Jiao Deyou didn't mean to find fault with Jia Xian, but he didn't want Jia Xian to give any advice to Wang from his heart.

Jia Xian is no longer as nervous as when he first came in, he nodded and said: "I'm just an example, let's say that in the second year of Huangyou, the price of rice increased from one hundred and twenty wen to one hundred and eighty wen per bucket in one year, and later rose to two hundred wen and one bucket. If I have 120 wen at the beginning of the year, I can buy a bucket of rice and sell it at the end of the year to earn 80 wen, but if I put it in the bank, I can only get more than 3 wen interest. There is such a huge disparity here, how can these rich people still keep their money in the bank? Jiao shopkeeper, a year's worth of rice won't rot. ”

Wang Bi knew in his heart that although what Jia Xian said was only a special case, and he only stayed at the stage of feeling, and had not yet risen to the basis of theory, he had already thought of using bank interest to regulate the market economy, and this Jia Xian was really a talent.

Jiao Deyou scratched his head, looking at Wang Bian as if he didn't understand, and Wang Xiang smiled: "Jia Xian is right, but Jia Xian, do you have any solution?" ”

At this time, Jia Xian lowered his head: "Lord Wang, I just thought of this problem, but I haven't come up with a solution yet." ”

"Hey, you kid, I thought you had it all figured out?!" If Jiao Deyou hadn't sat far away, he would probably have to give Jia Xian a neck slip.

Jia Xian said with a face full of grievances: "This can be solved by saying that it can be solved, and I don't know if the grain will rise or fall this year!" ”

"That's right! You don't know whether food goes up or down, and you don't know how much it goes up, right? Wang asked calmly.

"Uh-huh, uh-huh!" Jia Xian stared at the big eyes and nodded.

"Hahaha!" Wang Bian laughed heartily, seeing Wang Bian laughing Jiao Deyou also laughed with Jia Xian, Jiao Deyou was happy to see Wang Bian happy, and Jia Xian smiled a little embarrassed and was also infected by Wang Bian's smile.

"Okay, who is the guarantor you came to Yongzhou to work in the bank?" Wang Pan became more and more interested in this Jia Xian, he put his arms on the table, looking very relaxed, although Jia Xian couldn't think of a way for a while, but Wang Pan already had an idea in his heart.

"It's Qian Yilangzhong!" Jia Xian replied honestly: "Mr. Qian and my mentor Chu Yan are close friends, so I found Mr. Qian when I came and asked him to vouch for me." ”

Hearing that it was Qian Yi, the king remembered that the person who was poisoned by everyone in the palace was Qian Yi who came to prescribe medicine to everyone. With this person as a guarantor, I also saw that Jia Xian was not too far away. "Well, you don't have to go to the bank tomorrow."

Before Wang finished speaking, Jiao Deyou hurriedly said: "Lord Wang, although this kid Jia Xian is a little reckless, he is quite discerning in doing things......

Jia Xian thought about it, it seemed that the prince didn't like his suggestion, and when he came, Shopkeeper Jiao reminded himself to be cautious in his words. I was too proud just now, maybe I was unhappy with the prince. He glanced at Jiao Deyou gratefully, although this shopkeeper was rough and rough, he was still very kind-hearted.

"Haha, Brother Jiao, you admire this kid so much, I'll grab it from you, don't you mind?" The king laughed.

Jiao Deyou was stunned for a moment, then understood, and hurriedly called Jia Xian: "Stinky boy, you are really lucky, why don't you hurry up and thank the prince." ”

Jia Xian didn't reflect it all of a sudden, staying there and secretly wondering, the king saw him look dazed, thinking that this young man is a good counter, but he is like a blank sheet of paper without being sophisticated, and if he cultivates well, he will definitely make a difference in the future. "Jia Xian, what do you think of me leaving you to do things by my side?"

Jia Xian's mouth opened: "Ah! Good! But I can only count, I don't know what the prince left me to do by your side? I don't know if I can do it."

It's not fun to change ordinary people, this Jia Xian is quite real, Wang Bei believes that he is not wrong: "I want to accept a student, are you willing?" Wang Bian knew very well in his heart that although he could follow the future model and formulate the bank's articles of association, when it came to the details of specific accounting, he might not be as good as this Jia Xian. In particular, not only will the interest rate fluctuate in the future, but also the exchange rate against Goryeo and various foreign nations, all of which will have to be carefully calculated.

I have cultivated a Li Enxi, although she is a good talent, but after all, she is a woman and she is also a Korean, not to mention that Li Enxi's husband is a Wanyan impeachment bowl, and the days to come will be long, Wang Fang must train a few more capable assistants for himself.

The student follows the teacher, but it is not the teacher-student relationship now, and the master, in ancient times, had to be as respectful as serving the father. can be a student of the prince, who doesn't want this. What's more, who is not convinced by this little prince's character and talent? Not to mention being able to do things by the side of the prince. Jia Xian suddenly understood in a trance, and he knelt down and kowtowed: "Master is above, worship by the students!" ”

"Hehe, get up!" Wang Wei waved his hand: "You go back and clean up, come to the palace tomorrow to report, follow me for a few days, and then I will arrange for you to do things." ”

"Thank you, Lord Wang, no, thank you, Master!" Jia Xianle's mouth couldn't be closed. How did he know that Wang Bi was also secretly happy in his heart, and when Jia Xian was mentioned in history books and mathematics textbooks in the future, in addition to writing that he was under Chu Yan, he also had to write that he was under Wang Bi, which was a good opportunity to leave a name for himself through the ages.

Jiao Deyou looked at it and was happy, his brother was very informal, and a dignified prince actually accepted a guy from a bank as a student. After laughing, he said to Jia Xian: "You go back first, I have something to talk to the prince, and remember, in the future, you can call the master in private, and you still have to be honored by the prince outside." Also, don't do things under the banner of the prince, otherwise my Uncle Jiao won't be able to spare you first! ”

Jia Xian responded with a smile "yes", said goodbye to Wang Bei and Jiao Deyou, turned around and walked out of the study, he couldn't hold back his joy and almost trotted all the way out. I just walked to the moon gate at the corner of the corridor of the study annex, and bumped into Cai Jing head-on.

Cai Jing was not trotting, he almost ran all the way back: "Oh, stinky boy, you don't look at the road!" ”

Jia Xian looked up and saw that it was Cai Jing, and he recognized it as the young man next to the king, I wonder if this is also a student of the prince? That's my brother? He greeted with a smile on his face: "Senior brother, you are here." ”

Cai Jing's face was full of impatience: "What senior brother! Get out of the way! As he spoke, he pushed away Jia Xian, who was about to salute, and hurriedly walked towards the study.

Jia Xian shook his head and thought to himself, this person is so strange, the prince is so good, why is he so fierce. How did he know that Cai Jing was in a hurry at the moment, he ran to the study next to the king, pushed the door and said breathlessly: "Lord Wang, it's not good!" Something big is coming! ”
