Wu Zonglai's footsteps were hurried, and he didn't realize that a strand of his beautiful beard was swaying outside.

He is almost 40 years old. He can no longer become an astromancer, maybe he will never be able to become an astromancer for the rest of his life. To say that this time the fourth-level star warlock came to Shaonan, he must be the happiest person, and he will not let go of any calls about the star warlock.

Wu Zong was followed by his two young apprentices. It is said that Wu Zong's strength is not enough to accept apprentices, but there is such a lack of star warlocks, and most people focus on improvement and research. Some people are willing to The Association will not be serious about teaching apprentices.

When Lu Xu saw the person coming, he raised his eyelids and was still lying there. His politeness index is basically below the negative number, which is worse than that of a distinguished knight.

Cheng Jinzhou stood up and went to the entrance of the courtyard to greet them. He lowered his voice and said with a smile: "Warlock Liu Kuangxing and the others are studying their own things. I invited you here because I want to make something."

Wu Zong agreed repeatedly and peeked at the whiteboard where Liu Kuang and others were working, and his heart was filled with satisfaction. Just like the scientists of later generations, for insiders, each other's research results are open to each other, but they are somewhat self-conscious when facing outsiders. To be honest, the Star Warlock apprentice is not a Star Warlock, and his status is similar to that of a graduate student. How can a graduate student like Wu Zong without a mentor be a miserable person?

On the edge of the cleared table, there are various parts neatly placed, such as straight wood, hands, weights, etc., which can be used directly, but such as the dial base tray, etc., need to be modified again. Cheng Jinzhou looks forward to it. He looked at Wu Zong and said, "Can you make a scale?"

"A little bit." Wu Zong blinked. The education he received as a star warlock could only be described as barely adequate.

"I'm sorry to trouble you. We need to process the materials and make a few more precise balances." Cheng Jinzhou said, taking a piece of white paper and dipping a quill in ink to write the balance formula. From his posture From a personal perspective, it was hard to imagine that he was a 13-year-old boy, but everyone present had long been accustomed to his performance and only regarded him as a precocious genius.

When Wu Zong saw the scale in Jinzhou, he said a little unconfidently: "The best balance I have ever made, the accuracy is 0.5."

Even though 0.5 and 0.1 are both to one decimal place, the difference is far from as simple as 0.4, and the difficulty is naturally doubled.

"Make it first and then look at it. If it can achieve an accuracy of 0.1, you can also take one back and use it." Cheng Jinzhou has always been very skilled in generosity to others.

A balance with an accuracy of 0.1 is not valuable to a star warlock like Wu Zong, but if he can make one by himself, the meaning will naturally be different. Wu Zong nodded repeatedly, reached out and picked up the straight wood and prepared it. .

Cheng Jinzhou was not going to interfere with the first scale, so he let Wu Zong do it first and then look at it. The difference in star arrays makes each star warlock make things in a different way. The reason why it is difficult for physical balances to produce satisfactory accuracy is largely related to the ever-changing star arrays - on the one hand, star arrays speed up the processing of items. The production speed reduces the difficulty, but on the other hand, it makes the process design more complicated. It is difficult for any design to adapt to such a complicated star array. The final result still requires the star warlocks to adjust and experiment by themselves. On the contrary, when ordinary people make items, because they can continuously improve their craftsmanship on the original basis, the products of the best ones are already comparable to those of star warlocks.

The advantages of Star Warlocks in item production are mainly reflected in their knowledge and culture. Excellent craftsmen rarely receive a complete cultural education, especially in mathematics and physics. Therefore, in most cases, the craftsmen who make Star Warlock items still know what they are and don’t know why. The improvement of production level has a large extent. It is where the Star Warlocks developed and grew, and it is also a very interesting place.

Wu Zong was assisted by two apprentices of the Star Warlock Apprentice. They were both sixteen or seventeen years old, but they did not have the annoying appearance of later youths. Their faces were full of seriousness and caution. Even when delivering tools, they were extremely pious.

People's worship and yearning for astrology were unintentionally revealed in the two teenagers.

Wu Zong used a carving knife to gently carve the straight wood. First, he had to ensure that the weight (mass) on both sides was the same. If the scale required was very low, this would be enough. However, if you want to improve its accuracy, the most ideal situation is to make the mass of any two points of the straight wood the same. To achieve this, it is almost impossible without a star array.

In addition, the problem of adding screws in the center and both sides must also be considered. Similar to the positioning tools of later generations, before adding screws, the lines must be carved into the straight wood. As you can imagine, in this process, the balance of the straight wood is very important. may be lost. The weight of the screws will not be exactly the same. A good Star Warlock will take all factors into consideration. Under perfect circumstances, they can even improve the accuracy. Those famous Star Warlock item makers all have suitable Star Warlocks. Array.

After seeing Xiang Xin making the star array, Wu Zong's method was a bit too horrible to watch. Although his method is the same as Xiang Xin's back in the day, and is a standard method popular among star warlocks, Xiang Xin at least has a star array to use. He can balance both ends of a straight wood with one calcination, but Wu Zong's method is no different from that of ordinary craftsmen. The difference - when it comes to his ability to use knives, he is not as good as the latter's practice makes perfect.

On the other side of the table, two apprentices soon joined in the process of making the trays. The pallet is made by pouring a rubber-like substance on a wooden mold and letting it cool down. The production of molds is a little troublesome. Errors caused by different sizes or different centers of gravity will eventually accumulate. As for the mixing of pouring materials, there are also some skills. Impurities are unavoidable, but it is best to keep them consistent. It sounds complicated, but the tray is the part that least affects accuracy. During normal use of the balance, people often put paper of the same quality in the trays on both sides to hold medicines, so the accuracy error of the trays can be repaired.

Despite this, the apprentices still hope to do their best work. Looking at their serious appearance, you know that they must be strict with themselves.

By about 10 o'clock in the evening, Wu Zong finally completed a balance with an accuracy of 0.7. After a few corrections, it almost reached his best level.

Even such a scale is likely to sell for more than 50 taels of silver in a star warlock store. Therefore, Star Warlocks are a profession with no shortage of money. Most of the time, they are more willing to spend money to buy rather than make them themselves. Therefore, the prices of items that only Star Warlocks can make in the world remain high, and once ordinary craftsmen master them If you know the key, the price will drop rapidly and become popular. However, Star Warlocks are a profession that is short of money. Every experiment they do, or even every Star Formation they cast, costs a lot of money. If there is no limit on money, a Star Warlock can easily rise to the top. One or two levels, for anyone, this may be their lifelong goal.

Judging from the appearance, the balance made by Wu Zong can be said to be very good. The straight wood after hand polishing is shiny, the weights are exquisite and accurate, and the most difficult to handle weights are also made extremely smooth. However, after using it too much, According to Cheng Jinzhou of Standard Physical Balance, apart from the attractiveness of wooden materials, its use value is almost non-existent, let alone used in laboratories, even when weighing precious metals such as gold and silver, an error of 0.7g can kill people. But the price difference is a few dozen kilograms of grain. Compared with the necessary analytical balances and electronic balances in the 21st century laboratory, a balance with a precision of 0.1 is just a toy.

Such a balance is not even as accurate as the scales in the hands of gold and silversmiths. It is no wonder that the chemical development of the entire world is extremely slow - they still need too many preparations before the explosion.

Wu Zong sat on the chair with a blush on his face and said with a sneer: "I have studied land surveying a lot. I have no talent in item making, and it is difficult to obtain the relevant star formations."

To purchase a star array, you either have to spend association contribution points or spend money. Usually star warlocks are more willing to choose the former, because contribution points are not only currency, but also represent your star warlock level and the circle you can enter. Compared to the increase in Star Warlock levels, the value of money can easily be underestimated. The rarer the star array, the more contribution points it needs. Wu Zong is not yet an official star warlock. If he wants to obtain the star array, he can only get it like ordinary people. Naturally, it is difficult to obtain valuable ones.

Cheng Jinzhou nodded noncommittally and experimented with a few weights on the scale. He first used a ruler to draw lines on a white paper to represent the beams, and then used angles to represent the deflection of different weights on the balance. He easily found out the instability of the balance.

Wu Zong was sitting next to him and watching, his face getting redder and redder, but his expression became more serious. There were few opportunities for him to improve himself. For a 40-year-old middle-aged man, any time in Xingshu The understanding may be his last.

"The beams still need to be replaced with metal." Cheng Jinzhou glanced at Xiang Xin who was drawing on the whiteboard and said, "Although wooden beams are easy to carve, the wood is so uneven that errors are almost inevitable."

He also said the same thing to Xiang Xin.

Lu Xu had been jumping around out of boredom for a long time. After listening to it, he retorted to Cheng Jinzhou: "How can the metal beam be so easy to handle? It would be fine if it were me. Which of the three boys you called can carve on the metal?"

Cheng Jinzhou ignored him and continued: "It is also a problem if the beam is too long. The longer the beam, the easier it is to become unbalanced..."

Lu Xu simply laughed and said, "Don't you understand? The longer the beam of the scale is, the more sensitive it is."

"Who did you listen to?" Cheng Jinzhou's face was full of surprise. For a long time in the 19th century, this sentence was circulated in the balance manufacturing industry, but I did not expect that people in different worlds would have the same fallacies and legends.

Liu Kuang seemed to have stopped working on the whiteboard, turned around and asked, "Jinzhou, do you have a different understanding?"

"The length of the beam has nothing to do with the sensitivity of the balance." Cheng Jinzhou's eyes widened. Ordinary physical balances are not difficult in theory. In the final analysis, it is a matter of craftsmanship. He had already shown excellence in the balance theory, so it wouldn't hurt to earn a little more from it.

"Oh, why?" Liu Kuang came over with interest.
