Organ Throne

Xia Yu didn't reply. He had already learned the assessment criteria from Mrs. Huang.

The energy efficiency of 80% actually refers to the energy conversion efficiency, which is an indicator of the degree to which the source box can convert the source energy in the source crystal.

80% is relative to the standard, and this standard is set by the Federal Organ Division Association, which is quite difficult.

The source boxes purchased on the market can generally reach 90% of the standard, and it will be a little difficult to upgrade them later.

More than 95% is considered a fine product, and the one that reaches the 100% standard can be called perfect.

There are even things that exceed the standard, but those are the realms that only true masters can achieve, and ordinary people can't reach them.

Xia Yu has to take the low-level organ apprentice exam first, so he only needs to make a source box that reaches 85% to pass the test, which is not too difficult. For the intermediate level, you need at least 3 different types of source boxes to reach 90% on the 1 star source box, and at the same time you can make a 2 star source box with 85%.

As for the high-level, it is necessary to make 3 kinds of 1 star source box with a standard efficiency of 95%, and one kind of 2 star source box with 90%.

Xia Yu is not sure now either.

When he was chased by Cui Dalong, his perception broke through again, with 17 tentacles and a strength of nearly 4 meters.

During the month of physical recuperation, he spent most of his time researching various source arrays and source boxes, and the research goal was also changed from the previous 1 star to 2 stars.

The structure of the 2-star source array is much more complicated than that of 1-star.

Just like one is a plane figure and the other is a three-dimensional figure, it needs an extra layer of dimension, and it is much more difficult to build a stable specific functional structure.

Fortunately, Xia Yu knew his own strengths. With 17 sensory tentacles, he understood the Origin Formation very quickly.

After reaching the perception strength, he can almost quickly understand the various source boxes in Lao Chen's organization repair shop, and even tried to adjust those structures by himself very early on.

However, his current favorite 2-star agency, "Luo Sun", has never been able to understand it.

Once the interest came, he studied the "Sunday" source box for an entire afternoon, only to feel that the structure of the source array was very complex, bright, and mysterious, the part of understanding was less than 10%, and there were only some breakpoint lines each time. It appeared in his mind, and soon disintegrated.

Even the texture of the "Luminous Sun" source box alone made him feel amazing.

This made him feel that his level was still very low.

Of course, in the apprenticeship assessment of the agency, the real test is not to understand the structure of the source array, but to use the specific materials to make the source box, the skills, proficiency and so on.

Mrs. Huang couldn't teach these things, and he didn't have the time. He pondered it on his own with one or two very brief books, and then he just bought some jade yin sand to practice for a while.

So he didn't dare to think about taking a high-level apprentice exam all at once.

Gently poured some jade sand into the ceramic dish from a transparent jar, and Xia Yu began to grind the jade sand.

Yuyin sand, also known as Huangyin sand, is a special kind of ore particle, which appears yellow in sunlight. It is one of the most valuable associated minerals of Yuanjing. It is currently widely used as a material for the production of source boxes of medium and low star machines.

This kind of sand does not belong to metal, but it is much more special than common jade. Basically, it is only produced with source crystal.

Each of its grains is an independent crystal, the size of a rice grain, which looks crystal clear. After grinding and crushing, it will be turned into finer independent crystals.

And these tiny crystals are very sensitive to perception and energy, and when combined, they can "carry" the source array structure - after all, the source array is constructed in the human mind, and only this kind of extremely fine material that maintains an independent crystal structure can " It carries the "Original Array" and can be triggered by human perception.

In addition to Yuyin sand, common source box making materials such as gray crystal sand and Linlong sand have this special structure.

"I'm a novice again, I still want to take the intermediate test at this level, what a big dog!"

Here, looking at Xia Yu's apparently unfamiliar grinding action, the white-clothed steward felt a little contemptuous, and soon stopped paying attention to him, took out a book and read it for himself.

The market price of an ordinary second-order source box is hundreds of thousands of ohms, but the raw materials are generally around three or four hundred. The assessment of the agency association provides three materials for each source box, and the intermediate assessment fee is 2,200 euros, which is also a huge profit business. .

Some people from poor families are not absolutely sure and will never waste the money for this assessment.

Xia Yu ignored him, and patiently polished the jade sand with the grinding pestle. After ten minutes, the jade sand in the pottery dish was close to powder.

Seeing that the grinding was almost done, he carefully placed all the jade sand powder in a special heat-resistant plate, and put it into the Origin Energy Thermometer on the side.

Then, he activated his perception and slowly raised the temperature to about 1,700 degrees. Then, through the magnified observation window of the thermometer, he carefully observed the changes of the jade-silk powder in the heat-resistant plate, and adjusted the perception and control temperature. To ensure the molding of the jade invar.

Glue making is the second step in making the source box, and it is also a step that tests precise control and production experience.

Because of its special structure, even if it is ground into powder, each powder of jade incan is an independent crystal.

And when the particles are small enough, they can show different viscosities at different temperatures, which are called jade incans, and are suitable for source array structures with different characteristics.

The first thing Xia Yu tried was the common temperature-controlling source array, which required relatively delicate jade varnish.

After the summary of many senior masters, the jade-yin sand powder with a diameter of about 1 mm and a temperature of about 1700 degrees is more suitable for this source array~www.wuxiaspot.com~ But the specific operation depends on the size of the jade-yin crystal particles during production. , to determine the most suitable temperature.

If we say that grinding is the easiest preparation step in the production of the source box, then glue making is a meticulous work, which requires fine perception to control the subtle changes of each degree of the thermometer, and also requires a certain amount of experience to make judgments.

As long as these are well grasped, we can make the best quality jade infusion glue that is most suitable for perception and energy sensitivity through continuous attempts.

"Don't say, this exam costs a lot of money, at least the thermometer provided by the Human Agency Association is really high in accuracy, at least 2 levels higher than the one Lao Chen set up in the repair shop!"

And with 17 sensory tentacles, Xia Yu is still very strong in temperature control.

However, to evaluate whether the jade Yin glue is perfect or not, it completely depends on the experience of the organist. After all, he has too little experience, and roughly estimated that it can be done. He stopped the glue-making work, calmed down the perception a little, and then began to carry out the key Step 1: Congealing.

The step of condensing is also completed in the thermometer.

When condensing, it is necessary to fix the temperature in the most suitable state, and then directly use the perception cyclone to construct the source array structure in the mind, and then connect it to the jade gel through perception. At this time, the unique perceptual sensitivity of Yu Yinjiao will come into play, and the fine crystals inside will be reorganized according to the structure of the source array,

After the reorganization is completed and stabilized, the source box is more than half completed.

The last step is to make the jade-infused glue that has a new structure inside into a suitable shape, and then draw some lines to communicate energy on it.

These source patterns are all derived from the source array structure, which can be regarded as some supplements.

Grinding, gluing, forming, patterning - these are the 4 major production steps of a source box.
