Outside Hogwarts Castle, the grass near the willow.

Li Xiang is testing the Quick Equipment Wand device, which is a project that Li Xiang has been following up recently. At present, the preliminary tests are currently in place, and the effect of the Quick Equipment Wand device is very good.

"Demon set?" Draco showed an envious look, "Can every wizard be used?" Draco asked, thinking that according to his relationship with Li Xiang, he should be able to get one, right?

Li Xiang saw Draco's expression and knew Draco's thoughts. He smiled and said, "Don't worry! The magic set is suitable for most wizards. As long as the magic wand is not a strange shape, it can be compatible with the magic set."

For example, the wand used by a certain irritable Death Eater lady was actually curved and had a considerable amplitude. What could Li Xiang do except complain about that kind of alien wand?

Could it be that you need to modify the design of the Quick Equipment Wand device?

Don't think too much!

The price paid for a few examples and more perfect designs is too huge, and Li Xiang can't do that at all.

"Oh!" Draco was delighted and asked again, "What about the cost of this magic trap?"

Li Xiang considered that the cost of quickly equipting the wand device is roughly divided into three parts:

First, the design cost, including the appearance, structure, material selection, function, etc. of the quick equipment wand device, is in the design cost. However, it is a cost-free and has no clear cost limit, but it actually exists.

For example, from the first original version of the Quick Equipment Wand device to the current beta version, Li Xiang has made more than twenty versions in total.

Second, the cost of knowledge, the quick equipment wand device applies the relevant knowledge of alchemy and the Holy Light Magician, thus achieving a stable and fast wand pop-up function and a wand recycling function.

These two functions are completely realized by the fast-equipped wand device, which is equivalent to two wandless castings. In particular, the wand recovery function, as long as the wand is in the hand, it can directly return to the fast-equipped wand device.

At the same time, Li Xiang used alchemy to quickly equip the wand device, and realized one of the most important functions: mind connection control, which is the core function of the entire fast equip the wand device.

If this function is not available, how can we control the quick-equipped wand device to pop up the wand and recycle wand? Only through the mind control scheme can we enable the quick-equipped wand device to pop up the wand within two seconds, allowing the wizard to enter a combat state.

Otherwise, through other control methods, is it so fast?

The cost of knowledge is the same as the design cost, and there is no way to calculate how much it is. If you have to worry about it, the cost of knowledge is priceless. Because, except for Li Xiang, no one in the entire wizarding world can design a quick equip wand device.

The last cost is the cost in a conventional sense, that is, the visible cost that combines material cost and labor cost. Generally speaking, the cost that ordinary people pay attention to is only this cost.

Of course, in the wizarding world, advertising costs are almost non-existent!

Li Xiang thought about it before responding, "The main material of the magic set is composed of the life vine. The previous purchase price of the life vine required for each magic set was about 20 Jin Jialong."

Li Xiang paused for a moment and said with a smile, "However, at present, our Golden Griffon family has purchased a large amount of life vines, which has doubled the price of life vines. Therefore, the cost will rise a little."

"A core component of the magic cover requires some Moonlight Green Copper. However, the amount required is not much, and it should not stir up the market supply and demand relationship. According to the current price, it takes about 70 Jin Jialong." Li Xiang explained that Moonlight Green Copper is the material for the core of mental control, which is mainly used to communicate mental power.

"In addition, magic silk grass is also needed. The amount required is still very small, about 10 Jin Jialong can be done." Li Xiang mentioned another material. Magic silk grass is a special herb that can conduct magic power.

Although there are many materials that can conduct magic power, Li Xiang has only discovered magic silk grass at present, which can stably and calmly extract magic power from the wizard's body and inject it into a quick equipment wand device, so that the functions of popping up the wand and recycling the wand take effect.

"In the end, I need to make it myself. The production hours of each magic set take about 60 hours. I will convert this part of the production cost to 100 Jin Jialong." Li Xiang explained.

Perhaps 60 hours of working hours are converted to 100 gold gallons, which seems very expensive. But in fact, 60 hours of working hours are effective working hours, not casual and perfunctory things.

If you work for five hours a day, it will take 12 days to meet the production time of 60 working hours. For a technical wizard, even if you work 10 hours a day and work for six consecutive days and get 100 gold gallons, it is not too high.

Of course, the so-called 60-hour working hours are definitely Li Xiang’s nonsense. The real production process does not take that long. Especially with the help of magic, I’m afraid that after being proficient, the real working hours will not exceed 5 hours.

Draco comprehensively calculated, "If you consider the price of raw materials, the production cost of each magic set is about 200 gold gallons to 250 gold gallons?"

Li Xiang nodded first, then shook his head, "It can be said so, but it can't be calculated like this."

Draco showed a puzzled look, "How should we calculate it?"

"Since the process of making magic sets is very complicated, the success rate of making magic sets is not high." Li Xiang said, while taking down the quick equipment wand device and handing it to Draco, signaling Draco to watch it carefully first. "Look at the magic patterns on it, they all have special meanings, and they ensure the quick pop-up and recycling functions of the wand."

Draco looked carefully and found that on the slender vine of life, there were indeed many mysterious magic patterns carved, and Draco naturally did not know their meaning.

"At present, even if I personally make magic sets, the success rate will not exceed 50%. I have made three of the magic sets you are looking at now, and I have succeeded in this one." Li Xiang said exaggeratedly. The actual success rate exceeded 80%. Moreover, even if it fails, the most expensive moonlight green copper can still be recycled, and only the life vine will be wasted.

As for the magic silk grass?

That thing is the final process. When the magic silk grass is implanted, there is no possibility of failure. However, even if he has a good relationship with Draco, Li Xiang is not going to tell the truth.

After all, Li Xiang is preparing to use the Quick Equipment Wand device as a fist product of the Golden Griffon family. Hehe, don’t think that the Quick Equipment Wand device is a super durable product, just like a magic wand. In Li Xiang’s design, its shelf life is only three years.

Three years later?

Of course I want to buy another one!

Draco swallowed and asked hesitantly, "Even, will it appear at the Bojinbok Magic Store? If so, what price will it be sold?"
