For Zhang Kang, listening to the rain is not a way to make money, but another use. Although he is not a person who pities the fragrance and cherishes the jade, but after the twilight of the twelve rain beauties from generation to generation, there are not many people who enter the door of the noble eunuchs, except for a few people who choose to cultivate the Tao and cultivate Buddhism, most of them stay in the rain and teach the younger generations.

If they can still be on stage in the future and continue to chase for others, it will naturally be more useful than wasting it!

Therefore, when he and Zhang Shou walked out of the small courtyard one after the other, walked slowly to the backyard, crossed a small lotus pond, and stood in the middle of the wooden bridge, he glanced at the pond full of residual lotuses, turned around and looked at Zhang Shou and asked, "What does Dr. Zhang want to say to me?" ”

Zhang Shou shook his sleeve slightly, revealing the watch on his right wrist. Seeing that Zhang Kang was stunned for a moment, then raised his eyebrows, clearly remembering where this thing came from, he said bluntly: "Do you believe that Wei Nanbo has figured out the function of this thing?" ”

If someone else said this in front of him, Zhang Kang would definitely scoff, but Zhang Shou really showed extraordinary talent in many places, so after hesitating for a moment, he finally said half-truthfully: "Of course I believe what Dr. Zhang said. It's just that only the emperor looked at it for a while that day, but I didn't look at it carefully, can Dr. Zhang open my eyes? ”

Seeing that Zhang Shou did not hesitate at all, he took off the thing on his wrist with a smile and handed it to him, Zhang Kang was not polite, and took it and took a closer look. Although he was a barbarian in the eyes of others, he was actually a die-hard follower of Emperor Taizu's ideas, so he first tossed and turned around with the buckle of the strap, and then stared at the uniform scale on the round dial.

After a long while, he finally returned the things in his hand to Zhang Shou as they were, and then said thoughtfully: "Look at the scales on this round plate, could it be that this thing was calculated by Emperor Taizu when he set the key for the secret box?" ”

Uh, Wei Nanbo, you have a lot of imagination......

Zhang Shou couldn't laugh or cry, however, he couldn't despise the other party, because in this day and age, how could most people imagine how prosperous the world would be hundreds of years later? He coughed lightly, then took a step closer to Zhang Kang, showed the other party the clockwork on the right side of the dial in a serious manner, and then demonstrated how to wind the problem.

"I accidentally fiddled with this, and noticed that the needle on the watch began to move, so I observed it for a while, and found that a needle repeatedly, and it only took a moment to turn it around. The other two needles advance in different amplitudes. I didn't know what this meant, but when I accidentally passed by the sundial in the prison, I suddenly had an idea to wonder if this was a timekeeping thing. ”

Hearing Zhang Shou's explanation, when Zhang Kang looked at the disc that he once felt was in the clouds, he immediately felt that the fog seemed to be removed: "You mean to say that the scale on the disc that is like a cloth shop measuring stick represents the hour?" ”

He looked at the dial carefully, and unconsciously smiled: "I see that the big scale is a total of twelve, which should represent twelve hours...... It's just that an hour is four quarters, how can there be five small scales in a large scale? ”

It's just a little bit of a small problem with the difference between Chinese and Western timekeeping methods, Wei Nanbo, you don't want to be too drilly......

As for Zhang Kang's instinctive association with the twelve hours as soon as he found the twelve scales, Zhang Shou didn't know if the emperor had thought about it after looking at the watch and the codex, or if he hadn't thought about it at all, or if he felt that he had a lot of talent in this area, so he threw it to him to decrypt it, and he could only cough again.

"This is the fastest moving needle, and with each turn, the long needle moves a small scale. The long hand rotates in one circle, and the short hand moves by a large scale. And that didn't take an hour. I've looked at sundials, and they should be half an hour. That is, in a whole day, the short needle will make two turns around the disc......"

In today's era, Zhang Shou knows that the Western watch industry has only just begun to develop, and all pendulum clocks and pocket watches have not yet been born, so he patiently explained his "observations" to Zhang Kang.

Sure enough, Zhang Kang took a light breath, nodded heavily, and said, "I understand what you mean, if that's the case, then this thing is really an extremely precise timer." ”

He paused, stared at Zhang Shou and said with a smile: "At the beginning, Empress Han's father, Han Shantong, once preached that Emperor Taizu was after Emperor Huizong of the Song Dynasty, and after Emperor Taizu ascended the throne, he posthumously presented Han Shantong as the king. Dr. Zhang, do you think that Emperor Taizu is a descendant of the royal family in the Song Dynasty? ”

"Naturally not. The name of my dynasty is Ming, not Song, and Emperor Taizu never changed the surname Zheng to the surname Zhao. What's more, just such a subtle thing, Taizu has an extraordinary background. Seeing Zhang Kang's expression of approval and satisfaction, Zhang Shou continued, "This thing is a relic of Taizu, although the emperor gave it to me, I can't dismantle it because of this exquisite chronograph function." But because of this, I thought of something. ”

"Oh, what is it?"

Zhang Shou said bluntly: "The lamp leakage of Guo Shoujing's Daming Hall in the Yuan Dynasty. ”

Although Zhang Kang also showed him the globe last time, there is still a gap between the globe and the real astronomical instrument, if Weinan Bo Zhang Kang even knows this kind of thing, then this person must not be said to be a northern barbarian!

"Daming Hall light leak? Is it the Daming Hall lamp leak that was mentioned in the Yuan History Astronomical Chronicles, which was used to keep time? Zhang Kang raised his eyebrows first, and then said with a smile, "When Dr. Zhang said this, I also remembered that the Yuan Shi Astronomical Chronicles blew the sky wildly, and other strange things were recorded, remember that the lamp leak in the Daming Hall was hydraulic-powered, which is different from the things in your hands." ”

Speaking of this, he sighed and said: "Emperor Taizu said that one of the reasons for the chaos in the world at the end of the Yuan Dynasty was because those lustful people who were greedy for money had accumulated countless people, so that the people were not able to make a living. And after the chaos in the world, these guys either fled into Mobei, or were killed by the rebels from all over the country, so in the Yuan History Astronomical Chronicles, many Western Regions rituals have been lost. The lamp leakage of the Daming Hall in the capital of Yuan has long been burned. ”

Zhang Shou smiled and asked, "What about the elephant like the Song Dynasty's water transport instrument platform?" ”

"That's what Qin Tianjian is responsible for, I don't know."

Zhang Kang smiled dumbly, then raised his hands and looked at Zhang Shou and said: "Speaking of which, at the beginning, Taishi Ge and Qi Taichang had both been in charge of the Qin Heavenly Prison, so those Taishi officials in it were quite convinced of them, but a fledgling teenager like you was over-promoted, and they couldn't get used to it." So, if you want to provide the utensils over there, and solve the mystery of this timer in your hand, I'm afraid it's going to be difficult. ”

Zhang Shou didn't expect Zhang Kang to worry that Qin Tianjian's people would embarrass him. Not to mention the Qin Tianjian in this year, even if all the arithmetic geniuses in the country are exhausted, it is not easy to decipher the working principle of mechanical watches. Don't look at the first car in New China, which claims to have made the first car purely artificially, it is because at least there are lathes and other processing equipment, and the theoretical and technological level of these years is ...... Hehe!

At that moment, Zhang Shou smiled and shook his head: "I don't have the luxury of asking for the help of Qin Tianjian, I just want to improve today's timepieces." So, I want to say hello to you Wei Nanbo, and I will probably ask Lu Sanlang to invite two or three young craftsmen with good brains to go back and study. Not from the Ordnance Bureau, of course. ”

Zhang Kang didn't ask, why do you want to greet me stupidly for this kind of thing, after all, the last time Lu Sanlang detained a few craftsmen in that bookstore, he had paid close attention.

At this moment, seeing Zhang Shou's handsome face with a shallow smile, thinking that he was a foreign boy back then, but he was trusted and reused by Emperor Ruizong, and finally became an earl, and then read half a lifetime like crazy, he couldn't help but secretly sigh that if he is not crazy, he will not survive, and then smiled: "Since Dr. Zhang, you have this Yaxing, I, an outsider, wish you success in the future!" ”

"I hope to inherit the good words of my uncle!"

While desperately recalling his pitiful knowledge about clocks and watches, Zhang Shou deliberately told Zhang Kang a lot of plausible principles, and even the formula of the single pendulum principle was directly explained to Zhang Kang, of course, he didn't expect the other party to understand it at all. Seeing that Zhang Kang's eyes gradually flickered, and he clearly wanted to end this conversation quickly, he couldn't help but secretly breathe a sigh of relief.

In fact, in addition to the pendulum principle and escapement structure, the pendulum clock also needs a lot of parts, which is definitely not made quickly, and it is also a luxury to make.

But because it takes so long, studying this is a good way to fool outsiders and make those guys relax their vigilance against him who is addicted to strange things. And for the emperor who gave him something, it was also an explanation. Of course, if the pendulum clock can finally be made, it will be a thousand joys. During this period, those craftsmen can of course be used for other purposes under the guise of public and private interests.

When Zhang Shou and Zhang Kang returned to the door of the previous house, Zhang Shou only heard Lu Saburo shouting loudly: "Very good, sunny and rainy, it's you, everyone agrees, you come to play Li Xiangjun!" However, it's not that I look down on you, you have to write this story in its original form, I'm afraid that it's not a day or two, so don't write it all at once, write a paragraph, act a paragraph! ”

Lu Sanlang paused as he spoke, and then said with a smile: "You play a paragraph, and let the bookstore print this story you wrote and distribute it all over the city." Don't want money for the first few days, with your fame and this unique story, you still worry that no one will buy it in the future? Not to mention anything else, just those new eight-strand anthologies, with the story of this peach blossom fan, the book will definitely sell better! ”

"And when the play and book you perform are popular, I will invite everyone in the drama to sing with lyrics and sing all over the city, then it will be really popular and popular!"

When he and Lu Sanlang joked in the carriage that the book was not as good as the play, Zhang Shou had such an idea, and now he found that Lu Sanlang was so touchy, he couldn't help laughing. And Zhang Kang was ridiculous, glanced sideways at Zhang Shou and quipped: "Dr. Zhang, you are obsessed with arithmetic and strange weapons, but Lu San is obsessed with making money, there is really a teacher and an apprentice!" ”
