But no matter what, not to mention the huge amount of compensation, even Cheng Xiaoyu himself has already paid enough price, Pei Yanchen must care about him, and he is powerless. Starters, oh dear

There is still a week before Su Yuxi's birthday, Cheng Xiaoyu thought about it for a long time, and planned to make a gift for Su Yuxi by himself.

In his previous life, he was particularly particular about dressing up, and he would choose accessories carefully, but many accessories were particularly expensive, and he was not able to buy them, in order not to use the ordinary accessories that can be seen everywhere, he went to the gold shop to customize at the beginning, and did it according to the appearance of some big-name jewelry.

Because Japan is a big country in jewelry design and manufacturing, and Cheng Xiaoyu especially likes some Japanese craftsmen, Japan's unique craftsman culture has created the country's stubborn spirit of dedication to a certain skill, and these craftsmen who have achieved the ultimate have been named "national treasures in the world".

After watching the documentary about "National Treasure in the World", Cheng Xiaoyu became interested in the Mumu Gold introduced in it, and later by chance he learned to make zuò Mumu Jin, which is the Japanese translation name, which means the eye of the wood spirit.

Its origin is in the Edo period of Japan, Japanese samurai in the peaceful and prosperous environment to pursue some artistic philosophical appeals, and the katana is one of them, correspondingly due to the pursuit of the katana art form has also given birth to a large number of katana forging craftsmen, in order to adapt to the new market demand, many katana craftsmen strive to seek new metal decoration technology to design the katana.

Among them, Shigeyoshi Suzuki from Akita Prefecture, Japan, is the leader of this group of metalworkers, in order to pursue a decorative effect similar to the "cloud carving" process in Chinese lacquer art. Taking advantage of his mastery of metal, Shigeyoshi Suzuki created a "sword" (commonly known as a handguard or sword grid) using copper and red copper. It can be said that the birth of this work is also the birth of the wood metal craft.

This unique art form and metalwork fascinated everyone at once, and was later spread to the world by Western merchants. After the research of Western craftsmen to modern times, it has been possible to make Mume Gold present a very rich color with more than ten kinds of metals.

And in this time and space, it seems that this kind of craftsmanship is not common for zuò jewelry. Cheng Xiaoyu drew the drawings himself and passed them to Qiao Sansi to ask him to help make the zuò mold. He also helped buy gold, silver, and platinum in various colors. Thin flakes of eleven precious metals such as palladium.

The next afternoon, Cheng Xiaoyu did not practice the piano and went to SH Golden City. spent more than 700,000 yuan to buy a sea-blue Sri Lankan gemstone, and finally picked some broken diamonds, which did not cost money, they were all sent to Cheng Xiaoyu by the boss with a smile, after all, it is rare to see young high-rollers like this.

This gemstone is also the highest grade of Sri Lankan unburned sapphire, just not very large. Cheng Xiaoyu was also very touched when he thought that Su Yuxi gave him more than 9 million cash during the summer vacation, but he never signed the share contract. Although she knows that money is nothing to her, it is very heavy for Cheng Xiaoyu, who has come over, and the heavy weight is not the amount, but the fact that she treats you as a close relative, so it doesn't matter if she can give anything.

Cheng Xiaoyu also did not express his deep emotion to Su Yuxi, he has always disliked to express himself in words, he likes to use action, this time he took great pains to make his own gold jewelry, which is also a manifestation of his cherishing of this sister, he just wants to give her something unique.

Mume metal is a metal that is difficult to mass-produce. This special metalworking technique has been refined for use in contemporary jewellery design and manufacturing.

The existing wood grain metal making process is a metal sheet that combines different kinds of metals, such as copper + brass + silver. After staggered layering, it is welded into one piece by static pressure and high temperature, and then processed by forging and carving to finally form this special wood grain metal.

Cheng Xiaoyu chose eleven more expensive metals as raw materials, and the cost was even more terrifying. There is no other trick to choosing different metals, just the annealing temperature is different.

The reason why mass production cannot be achieved is that the traditional wood grain metal manufacturing process has many technical difficulties, including the selection of metal materials, the control of surface treatment, pressure and temperature, and the pattern treatment of the surface of the material, and the loss is large. The yield is very low.

Qiao Sansi brought the raw materials that Cheng Xiaoyu wanted, picked him up in SH Golden City, and went to a metal forging factory on the outskirts of SH City.

Cheng Xiaoyu arrived at the ground. First of all, the washed wood grain metal raw material is quickly wiped clean, and then 11 kinds of metal plates are added. Each two pieces are staggered and stacked on the mold, put the fastened mold into the stainless steel foil box, pour the charcoal particles into the stainless steel foil box at the same time, and call the master to put the sealed stainless steel foil box into the electric kiln.

Then he said to the master: "Keep the constant temperature for 4 hours, turn off the electric kiln, take out the stainless steel foil box, and cool it naturally to room temperature." Fearing breakage and striving for perfection, he made a total of five molds.

After four hours of patient waiting, the rough blank of Mumu metal has been made. Cheng Xiaoyu also instructed the master to sawh off 1-3 mm width along the perimeter of the wood mesh metal rough blank to ensure that there are no cracks around the wood grain metal rough blank.

The next step is to get in shape, which is another tedious process. The annealing temperature of the wood grain metal embryo must be controlled at 600C-680C, and it is naturally cooled after annealing, and the wood grain metal embryo body is forged and rolled, and the thickness is reduced by one-tenth of the thickness, and it needs to be annealed again. Fortunately, Cheng Xiaoyu only needs to command this matter.

When the wood metal blank is forged to 3-5mm, you can start the pattern making of wood grain metal: knock on the drill, mill and twist corrosion, and put the obtained wood grain metal pattern into a 50% concentration nitric acid solution for corrosion for 30 seconds to 5 minutes.

By the time the zuò was finished, it was already late at night, but the few masters who stayed until the end were amazed, and it was the first time they had seen such a beautiful texture and wonderful color metal.

In the end, five molds were successfully created, and two semi-finished products that Cheng Xiaoyu was satisfied with were successfully created.

Cheng Xiaoyu used the box to pack the pleasing feather-shaped wooden gold and take it home, and the next stage is to carve the chisel slowly. What he wants to do is the goro\-s feather designed by Goro Takahashi, who was famous in his previous life, and there are no accessories of this brand in this space.

To carve beautiful lines on wood and gold, it takes a lot of chisels of different thicknesses and curvatures, and a lot of patience and meticulousness. Cheng Xiaoyu has always been able to get the pleasure of making a thing and completing it beautifully, he is engrossed in carving the feather pattern under the table lamp, and making the groove inlaid with gems between the root of the feather and the stem.

He used pavé settings with a halo of tiny diamonds of various colors around the aquamarine Sri Lankan unburned sapphires. In this way, you can achieve a luxurious and shocking effect.

Often, the use of a large area can create a brilliance on the entire surface of the jewelry, and can also be used as a peripheral decoration for the main stone, highlighting the nobleness of the center stone.

After the setting was completed, Cheng Xiaoyu carefully looked at the sapphire-encrusted feathers under the light, and the dense arrangement gathered the light of the small gemstones, making the jewelry look particularly sparkling. And that drop of sea-blue gem is as crystal clear as the tears of the sea god, and with the mysterious and complex color of Mumu Jin, it is as dazzling as an ancient artifact.

After this qiē is sanding, which requires great patience and to give the metal the most beautiful shine, it requires a cloth made of sisal, a tropical plant fiber.

With a good tool, you need to apply a wonderful force, and the metal friction and heat generation will cause skew, so you need to ensure good heat dissipation while grinding.

Cheng Xiaoyu tirelessly completed this qiē, it was almost morning, he liked to make jewelry in one go when he had a feel, so that the works produced were more complete and more beautiful, and the works completed several times were not as delicate and durable as the works completed in one go.

In the end, Cheng Xiaoyu carefully engraved four words on the back of the feather, Midwinter Feather, Midwinter represents November, he was born in November, eleven metals represent the date, and his birthday is November 11th.

This delicate and beautiful feather to the extreme, is Cheng Xiaoyu's most satisfying work, he never thought that he could do so well, there is no more perfect pendant than this, and there is no jewelry that has poured all his efforts and wisdom into it, and can express his mind more.
