Chapter 116 Two Discs
The group of four came to Yu Linglong's factory building again, still in the huge sealed container on the second floor, the four of them stood there waiting for Yu Linglong.

While waiting, Chen Ziyang glanced at the items in the grid above the ground. The old copper tripod was gone, and several things in the other grids had been replaced. It seemed that Yu Linglong was really I'm very busy. I don't know how many self-righteous collectors will be trapped when these things are released on the market.

After a while, Yu Linglong walked in from the door of the container carrying a plate.When she came over, several people looked at the things on the plate in Yu Linglong's hands, and they were all stunned. There were actually two gold discs on the plate!
"Miss Linglong, you have been troubled for the past two days, but why are there two pieces of this thing?" Wang Chuan didn't understand Yu Linglong's intention. He originally only asked him and her to help make a copy, but he took out two at once. Could it be that Yu Linglong has also started to buy one get one free?Wang Chuan quickly asked the reason.

Yu Linglong lit a cigarette, took a puff, then pointed at Yang Lei, and said, "You should really thank him for having so much flesh on his buttocks, and the wax that was cast on his body. In the mold, I found that there is something like a seam on the edge of this disc.

Later, when I recalled what you said, this thing may be a gear, so I understood the reason.This disc is just like what you said, it should be a gear, but the slot around the gear is hidden inside the disc.

There is a circle-shaped pattern on the front and back of the disc, and the two circles on the front and back are the same size. I guess this circular pattern should be something like a bearing, which can rotate and hide behind the circle after turning. The gear slot inside the disc will be exposed.

But because the lines on the side of the disc are not very clear, I can't judge the width of these gear slots. I roughly judged that these slots have two possible composition methods based on a few obvious traces, so I just Made two replicas for you, the two gear slots are different in width and length. "

After listening to Yu Linglong's words, Chen Ziyang and Wang Chuan looked at each other, and then each of them held a disk, pressed the front and back of the center of the disk with their thumb and index finger respectively, and then slowly turned the disk s surface.Sure enough, just as Yu Linglong said, with the rotation of the disc, the several slots hidden in the middle of the disc slowly protruded out, turning into the shape of a gear.

The two of them nodded at the same time as if they had suddenly realized what is called professional quality and what is meant by industry morality, which was vividly displayed on Yu Linglong's body.This is really a way to steal, Chen Ziyang thought to himself, don't think that Yu Linglong is just a fake, but with this rigorous energy, it's no wonder that she can achieve today's achievements.

Seeing that several people understood what she meant, Yu Linglong continued: "As for the material of this disc, I'm sure that the prototype of this disc is definitely not made of gold. It is estimated that there is only a thin layer of gold plated on the surface of the disc, the purpose is to look good.

Gears need to bear weight, and gold is too soft to bear too much weight at all, otherwise it will deform and lose the function of gears.Combined with what you said that the disc may have been cast in the ancient Bohai state, I estimate that the original disc was mainly cast from copper.

During the ancient Bohai Kingdom period, the Bohai Kingdom had to pay a large amount of northern specialties to the Tang Dynasty, such as mink fur and medicinal materials, and they had to be donated to the Tang Dynasty on time.At the same time, a large amount of copper was also donated, so it can be judged that the copper smelting industry in the ancient country of Bohai Sea was relatively developed at that time.

But copper is ductile and not suitable for making gears, so I guess the material of this disc is actually a copper alloy, most likely a special brass alloy.Brass is an alloy composed of copper and zinc.If it is only composed of copper and zinc, it is called ordinary brass.Brass is now often used to make valves, water pipes and other objects.

If a variety of alloys composed of more than two elements are called special brass.Lead, tin, manganese, nickel, iron, silicon, etc. can be mixed with brass to form a special brass alloy.

The combination of different elements and copper will lead to different characteristics of the alloy. In fact, it is not that the smelting of alloys was very developed in that period, but that the copper purification in that period was not as good as it is now, so other elements are often mixed in copper. It can be said that the special brass of that period was produced because of insufficient copper purification.

Special brass is now also called special brass, which has high strength, high hardness and strong chemical corrosion resistance.Generally, the copper content is about 62% to 68%.The two discs in front of you are both made of this special brass alloy, I hope you are still satisfied. "

After listening to Yu Linglong's long speech, several people were dumbfounded, their mouths were so wide open that they could almost stuff a goose egg inside.

Yu Linglong's words are reasonable and reasonable, and she doesn't know how much knowledge is packed in her little head.Yu Linglong was able to analyze this disc so thoroughly with just a few words and trivial fragments provided by a few people, plus the background of the ancient country of Bohai Sea. thumb.

In fact, it was of no use for a few people to ask for this disk. All they wanted was the map of the Bohai Underground Palace on the disk. missed.

Because Yu Linglong had helped them completely extract the patterns on the disc before, so this disc was not of great significance to Chen Ziyang and the others.Their main purpose is to sit on the sidelines and wait for Lin Xueping's arrival, and they don't need to enter the Bohai Palace.

Although Wang Chuan was once moved by the treasures in the underground palace, to him at this moment, the life of his daughter Wang Lele is more important than anything else.Chen Ziyang and the others also had the same idea. The purpose of their stay was to wake up Wang Lele. Otherwise, they would be in Big Walnut Town now, talking and laughing while drinking.

Although everyone likes money, it has to be spent. After going through so many things, they don't want to put themselves in danger anymore. Besides, although they don't have much money now, it is enough for them to be safe. Live the rest of your life steadily.

Although this disc is not very important for this operation, Bao Buqi can be used when looking for Lin Xueping, and at the same time, there is a great possibility that it can help Chen Ziyang decipher the secrets of the above map, so several people Also very happy.

Wang Chuan handed Yu Linglong a check again, paying for the production of the two discs.After saying goodbye to Yu Linglong, on the way back, Wang Chuan kept persuading Chen Ziyang to let him relax. Even with his level, he was unable to decipher the secret of the map on the disk in such a short period of time. Maybe there is no progress on Lin Xueping's side, so don't worry.

Chen Ziyang knew that what Wang Chuan said was just to relieve the pressure on his heart, so that it was more likely to crack the secret of the map in a short time.In fact, Wang Chuan was more anxious than anyone else, Chen Ziyang could see this, but what's the use of being anxious?I have really tried my best.

Before Chen Ziyang thought that even God was helping them, first by chance, the red-hot disc left two marks on Yang Lei and Shanshi Shuai, and then he met Yu Linglong who A capable person copied the disk.

Wang Chuan's team is almost organized, Ushishishuai's equipment is basically all in order, Yang Lei has also absorbed a lot of knowledge about the ancient country of Bohai Sea, and he has obtained the application of gossip from the ancient country of Bohai Sea from Xiao Siyan'er. A lot of such an important clue.

Originally, everything was moving in a good direction, but now it was blocked by an insurmountable gap that could not crack the map.
