By the Santai River, Yuwen Wenzheng and Yang Ji checked the operation of the hydraulic clock in the workshop. This is a large-scale device that has been verified by technology and has been operating continuously for more than a month.

It just kept running normally, and the accuracy was too bad for people to look at it. According to the daily results, the daily operation deviation of this clock is nearly half of the incense stick.

Moreover, the daily deviations are slightly different, which shows that the operation of the entire device is not really uniform. In scientific terms, it means that the "system error" is very large. The continuous fluctuation deviation indicates that the stability of the device is not good.

It is said to be a clock, but in reality it seems to be a toy, but Yuwen Wen is very satisfied because he is not in a hurry.

First solve the problem of existence or not, set up the device and run normally, slowly find out the problem during operation, and then continuously adjust. If one month does not work, it will be three months, if three months does not work, it will be half a year, and if half a year does not work, it will be one year.

What's more, this hydraulic clock is now for craftsmen to practice and accumulate experience through long-term operation. It is actually unnecessary to have a clock as big as a house. It is not an imperial guard and does not need to simulate the operation of celestial bodies.

The purpose of building a huge hydraulic clock device is to give the craftsmen the most direct experience. The hydraulically driven clock is of course not practical, so that the power of the clock can evolve, first of hydraulic power to gravity pendulum, if metallurgy can be done, it is clockwork.

From large clocks to small clocks, from small clocks to pocket watches, then the day difference of clocks is reduced to minute levels, and then strives to slowly reduce to second levels. This will take many years and months, or how much money it will cost to succeed.

"I'm sorry, please forgive me for saying that the clock is not very useful, so why bother to spend manpower and financial resources?" Yang Ji advised again. He had already elaborated on his opinion in detail before, believing that the clock was flashy but not practical, and that the military and the people did not have much practical significance.

"If you use farming, weaving, marching and fighting, it doesn't matter whether there is a clock, but it's not very useful..." Yuwen Wen still didn't repent, "It depends on where it is used."

"Please give me some advice," Yang Ji asked.

"In terms of alchemy, reaction time is very important. It is impossible to say that burning an incense stick at a high fire is a different time. If one incense stick, the incense burning speed in all parts of the country is different."

"Empress, alchemy is an evil way, why don't you believe in the so-called immortal elixirs of immortality?" Yang Ji was excited when he heard the alchemy. "I missed Emperor Shizong of the Ming Dynasty because I am obsessed with alchemy..."

'Give me back to the Ming Dynasty, I Emperor Shizong! Brother is the Southern and Northern Dynasties! What are you talking about Jiajing?' Yuwen Wen complained in his heart that Yang Ji is good at everything, just when he talks about things, he likes "My Ming Dynasty". This era has been nearly ten years before him, and he still misses the Ming Dynasty.

"Alchemy is not useless. Isn't fire medicine discovered first by alchemists?" Yu Wen Wen helplessly enlightened the other party, "The same is true for Western alchemy. Researching various formulas to refine objects, one of the important measurements is time."

He looked around and was sure that no one was nearby or eavesdropped. He simply revealed the biggest secret: "Do you know the Western navigation technique?"

"Western Navigation? Remember to follow the latitude and longitude... But what does that have to do with the clock..." Yang Ji recalled, and suddenly came to his senses after he said: "Your Majesty wants to measure the longitude?"

"That's it." Yuwen Wen nodded solemnly. At this moment, he transformed into a one-eyed pirate captain with a one-eyed and footstepped with a hairless parrot on his shoulder, directing the broken sailboat to sail eastward in the Pacific Ocean. Just as the crew members were crying and going back to sail, endless land appeared on the sea level ahead.

"Encourt! If the Turks have not yet been pacified today, the Turks are eyeing them, Goguryeo's ambitions, Tubo is about to rise, and Nanzhao..." Yang Ji was even more excited than him, "The navigation cost a lot, why bother doing such a waste of money and money!"

Yuwen Wen coughed dryly. He didn't expect Yang Ji's view of navigation was so negative. The other party seemed to turn into Liu Daxia and stood in front of him. The Ming Dynasty Minister of War was said to have burned Zheng He's chart and is now passionately accusing him of ruining the country and harming the people.

The importance of navigation is unquestionable. Although he had many arguments to refute Yang Ji, he finally decided to underestimate it: "I want to eat chili peppers!"

Yang Ji was stunned when he heard this, his mouth moved and wanted to say something, but he couldn't say it. He heard the other party say he wanted to find corn, sweet potatoes, and potatoes, and finally returned to normal. He knew that these three things were important crops.

"You are right. The world is not determined. It is not a wise move to spend manpower and material resources to sail, not to mention that I am not safe." Yuwen Wen agreed with some of Yang Ji's opinions. He is now curled up in a small state with few lands and sparsely populated areas on the Yangtze River. It is still unknown whether he can save his family's life. It is a delusion to plan a large voyage now.

"But without a single step, you can't reach a thousand miles. If you want to have a useful precision clock, it may take decades." He continued to elaborate on what he thought, "Even if our dreams cannot come true, leaving a solid foundation for the next generation to realize them, what's wrong with opening up territory for our Chinese people?"

"It was the misunderstanding of the officials." Yang Ji bowed and bowed. When he heard that Yuwen Wen had an intention to sail, he was worried that this person was too ambitious and might not be sure of protecting himself, so he thought about sailing. It was really putting the cart before the horse.

"You are the ones who are stubborn and longitude are not only used at sea." Yuwen Wen smiled. As a person who has received modern education, he knows a lot about the uses of longitude and longitude, "Besides, the precise time is indeed very important."

To be fair, for agricultural society, a clock that is accurate to the minute is useless because people do not need to be "on-time". The folk use of astronomy related to time is to formulate a calendar and let farmers know the solar term.

Scholars, farmers, industry and commerce work at sunrise and rest at sunset. No one needs to be accurate to the "on-time" minute. Farmers get up when the roosters crow, go out to farm at dawn, rest at noon when the sun is too strong, and continue to do farm work in the afternoon. When the sun sets, they will naturally finish work and go home without looking at the clock.

Craftsmen don’t need it. They work every day at dawn and finish work late. The same is true for merchants. Even if officials click on Mao or go to court, they always look at the time. At most, the army needs to know the time at most. Therefore, there is no need for a clock in an agricultural society.

The European-style bell tower is now useless in the cities of the Central Plains. The opening and closing of the city gate can be based on the carving and sundials. Every hour, it will be beaten and transmit the sound. At night, there is a curfew that is worth the time to beat the bangzi, and no one needs to watch this kind of thing.

The reason why Yuwen Wen wanted to make a clock is very simple: realistic needs. It is not only a high-level measurement of longitude, but also a purpose of making a navigation clock immediately, but it is purely a need for experiments.

First add a certain milliliter (or grams) of substance A, then add a certain milliliter (or grams) of substance B, react for a certain minute, and then the next step. This is a normal scientific experiment and a necessary parameter for experimental reproducibility.

Volume and weight have already weighed and weighed in this era, but time is very thick, one stick of incense, half a stick of incense, one quarter of a stick of incense, and a cup of tea. Unless there is a standard incense standard tea, this is completely metaphysics.

There are also blacksmith shops, such as forging iron tools, annealing, and quenching, which are entirely based on experience. This kind of experience can only be passed down from generation to generation by master and apprentice, and it is impossible to quantify it at all.

For example, the wind pounding rice, water conservancy pounding rice, how much can the rice pounding device be pounded within a certain period of time. This is an important parameter for quantifying the ability to pound rice. It does not have a frequency of minutes, and can only be calculated based on one stick of incense. Although this does not affect the use, craftsmen can only rely on experience to further improve their efficiency.

Or it is a hydraulic forging hammer evolved from a hydraulic rice pounding machine and a hydraulic bellows (water discharge). The important indicator for evaluating their capabilities is how many hammers can be hit per unit time, or how many times it can be traveled per unit time.

Of course, it is okay to use etching and hourglass as a timing tool, but Yu Wenwen must use scientific measurements to the best of his ability. Doing things strictly according to various parameters is the right way for the workshop to produce.

Although this has nothing to do with siege, and it doesn’t even matter whether there is a clock or not, if you want to ‘scientific’ various workshop production processes, accurate time is essential.

Yang Ji looked at Yu Wen Wen in a daze and was a little surprised. He didn't know what the person in front of him was thinking, so he would giggle for no reason. Although he still didn't understand why the other party was so persistent in the clock, Yang Ji decided to do his best to get the qualified clock out.

Lin Youdi was staring at these two people in the distance. He wanted to report to the Lord of the Langzhu, but he saw that the Lord of the Langzhu and Mr. Yang were arguing about why. Lin Youdi knew that he could not go forward at this time, so he waited until the two of them had finished arguing before getting closer.

He came to report on the problem of the hydraulic clock. What the Lord asked was not to be afraid of problems or not to know how to summarize the problems. So now is the time for him to report the summarized problems.

"With Mr. Yang... Mr. Yang said that the clock is fully responsible for this." Yuwen Wen said that Yang Ji's name in the mansion is "Mr. Yang". He will not miss any opportunity to "squeeze" Yang Ji's knowledge.

Another reason is that Yu Wen Wen did not understand the structure of clocks. In that era, he saw that time was either a mobile phone, a quartz clock or an electronic watch, and he had no idea about the structure of mechanical clocks.

Yang Ji listened carefully to Lin Youdi's report. The problem of unstable operation of this hydraulic clock is very simple: the accuracy of each component is not good, and the errors of each component accumulate later, resulting in extremely poor operating accuracy.

Especially most of the components are made of wooden, and the engagement between the ratchet and ratchet is easily damaged, and the rotating shaft is easily worn. Of course, due to lack of experience and improper operation, it also causes unnecessary damage.

Lin Youdi summarized the opinions of the craftsmen. First of all, everyone is familiar with the structure of the hydraulic clock, and secondly, the solution is: shut down and retouch the components.

Unqualified parts need to be replaced. Given that wooden parts are prone to wear, I hope to gradually replace some parts with iron. Anyway, Lin Youdi talked for a long time and said a thousand words, and he summed up two words: money.

For Yuwen Wen, what can be solved with money is not a problem. If there is not enough money, you can find a solution, but you are afraid that it will not be solved by spending money. If it weren’t for the price but the market, he would have sold his money to save a group of war horses.
