At noon, Shang Fangjian was in charge.

"Report to King Donglai, the chronograph has been made, there are ten in total. In particular, the five largest ones, according to the will of the prince, are made of gold and are dedicated to His Majesty's birthday! Judge Sun Heng took a few officials and brought six well-made bells to be placed on top of the big case in Wu Yan's office.

Today's Wu Yanzhi is already famous all over the world, and his position is high and powerful, so the judge Sun Heng naturally respects him even more.

And his position has also been promoted to the palace servant imperial history, although this grade is only seven grades, but it is also an important position in the Great Zhou.

"Hmmm! You're pretty good! Wu Yanzhi looked at these six bells of different sizes and was very happy!

Your Majesty's birthday is left in seven days. There were three kinds of gifts that I had prepared, one was five large clocks made of gold; The second thing is five huge dragon beds; The third thing is five sets of sofas.

There are many places where the emperor lives, and this thing naturally has to prepare five sets, the so-called Ninety-Five!

Because almost all the manufacturing of instruments in the palace was supervised by Shang Fangjian, it was extremely convenient for Wu Yanzhi to arrange it.

Anyway, it was a gift to the emperor, and no one dared to oppose it.

The dragon bed is, of course, Simmons!

Wu Yanzhi took a bell to take a look, it was not bad, the workmanship was very exquisite, and it was worthy of the craftsmanship of the senior craftsmen in the royal workshop of the Great Zhou!

"Are these chronometers accurate? How much is the error? He asked the four craftsmen who made it.

Deng Ziyu, who was the leader, said: "King Qiqi Donglai, villains and others have processed more than 20 of them, and these ten chronometers are much more accurate than those hourglasses of the Taishi Bureau. Of course, in the process of walking, there may be some problems, which will need to be repaired. ”

Wu Yan listened, is it more accurate than the hourglass of the Taishi Bureau? Looks pretty good.

"How much does this make of a piston?"

"Each one uses about five catties, plus some miscellaneous expenses, it's not too expensive! Now the price of this fish has dropped, and it is about the same as ordinary copper. ”

"Well, that's good, this thing doesn't have the will of the Holy Lord, and I don't dare to produce more, Shang Fangjian will produce these for the time being!

I will have the materials prepared and a private workshop in Luoyang, which will be specially produced from tomorrow. This thing is also invested by others, you can use the time after work to produce, you can get double the income, and there will be a big reward at the end of the year! ”

When those people heard this, they were naturally very happy! In the past, they followed Wu Yanzhi to the south for a walk, and each of them earned fifty or sixty yuan in a year, plus bonuses, which was better than their income in seven or eight years.

Wu Yan said that the cost of the bronze bell material is roughly more than one in the past, counting the labor cost, but it costs three to four times.

Then this price can't be sold cheaply. When the time comes, divide the bell into several ranks.

The best ones, with some self-made glass, and precious stones, etc., are added to it, and it is according to five or six hundred yuan each. Then downgrade in turn, the cheapest, that is at least 50. It is estimated that the two capitals of Chang'an and Luoyang alone will not be a problem to sell tens of thousands.

If there are still foreign businessmen to buy, the sales volume of this thing is even more difficult to estimate, as for how much money can be earned, hundreds of thousands of yuan?

"Judge Sun, send all the chronometers produced, except for these five gold ones to the emperor, and send the rest to the Sifu Temple and hand them over to deal with!"

"Yes."

Sifu Temple (Taifu Temple) is the management of the country's money and treasures. This timekeeper is produced, which is a treasure

"Judge Sun, the production of gunpowder and firearms carried out by the firearms department in the management workshop must be kept secret!"

"The subordinates obeyed. However, the production of this gunpowder is not easy to keep secret, and perhaps the people will soon grasp it! Judge Sun reminded.

"Not necessarily, they can only master simple recipes, but it is not easy to produce gunpowder of our quality." Wu Yanzhi said.

Wu Yan later came and arranged for Cui Shaojian to finish the work of Shang Fangjian, and then ordered someone to bring all the things into the palace.

……

"Your Majesty, King Donglai brings the birthday gift made by Shang Fangjian to see me, this is a gift list!" Shangguan Wan'er said.

Wu Zetian nodded, took the gift list and looked at it: Long live the chronograph, the fairy bed, and the free chair.

What is all this? She's weird.

"Let him bring it in."

"Yes."

After a while, a large group of people carried five golden clocks, a dragon bed, and a set of four sofas in!

"Weichen see Your Majesty!" Wu Yan stepped forward and bowed.

"Yanzhi, it's rare for you to be so filial, I'm very happy. What is this Viva chronograph? ”

Wu Yanzhi took a golden bell and explained it carefully to Wu Zetian: "Your Majesty, this long live chronograph is a very strange thing!" Your Majesty, please see, just twist this switch tightly, and it will tell the time.

Your Majesty, don't underestimate it, Wei Chen asked the craftsmen under his hands, he is much more accurate than the hourglass made by the Taishi Bureau! That is, all the hourglasses in the palace now are not as accurate as this timekeeper!

This thing can go on for decades and hundreds of years. So Weichen named it Long Live Chronograph. A total of 22 units were produced and 12 were available.

These five gold shells are made to celebrate my grandmother's birthday! ”

"Oh, so wonderful? Tell me what these symbols mean. Wu Zetian looked at the Arabic numerals on it and was very surprised.

"Your Majesty, this is a symbol invented by Wei Chen for counting, and it is very simple. Your Majesty, please see, the number at the top means 12, and the number next to it is 1.

The largest hand, from 12 to 1, represents half an hour. The number next to 1 is 2......" Wu Yanzhi began to explain to Wu Zetian slowly.

The numbers are very simple, nothing more than the use of Arabic numerals instead of Chinese characters.

The pointer is very complicated, Wu Yanzhi spoke for a long time, and Wu Zetian understood it.

This mainly involves the difference between the time of this large clock and the ancient timekeeping. In ancient times, 12 hours were used, each of which was two hours.

However, in ancient times, it was a hundred moments, and the big bell of Wu Yanzhi was 96 minutes in later generations. That is, an hour and four quarters, which is more scientific.

If a hundred ticks are used, it is difficult to display on the large clock.

"Your Majesty, Weichen requests that the 100 quarters of the day be adjusted to 96 quarters. So the hourglass is the same as the Viva chronograph. Wu Yanzhi pleaded.

"Why not? Wan'er, I'll make it later. But, my grandson, I find this symbol you invented to be even more useful. It saves us the trouble of keeping a diary. ”

Wu Zetian saw the huge role of these Arabic numerals at once.

"What Your Majesty said is very true, and Weichen also has this intention. Wechen has prepared a few blank pieces of paper here, and is preparing to demonstrate the benefits of this symbol to His Majesty in detail! Your Majesty, please see. ”

Wu Yanzhi took out the white paper, as well as the charcoal pen made of charcoal, and began to demonstrate the wonder of the symbols.

In fact, it is simple addition, subtraction, multiplication and division, as well as counting.

Wu Zetian and Shangguan Wan'er and others were stunned! Please Baidu "Throw Book Network" Thank you for your support!
