"And how much does it cost?"

"It depends on the variety." Rose said: "This kind of crystal ball is divided into two categories, each with three capacities, a total of six different models. The capacity of the crystal ball is divided into three levels: 1,000, 10,000 and 100,000, and the one in your hand is a medium-sized magic storage crystal ball with 10,000 mana. In addition, according to the conversion ratio of mana absorption, it is also divided into high-efficiency type and normal type. The one in your hand is a normal type, and the conversion rate is about 1/20, that is, you enter 20 mana and successfully store 1 mana. The efficient type has a slightly higher conversion rate, which can be about 12 to 13 to 1. Among them, the cost price of ordinary crystal balls is thirteen, sixteen and twenty respectively according to the different mana storage capacity. ”

"Crystal coins?"

"No, silver."

"What? I only need sixteen silver coins in my hand? Isn't that converted into * RMB for just over a dollar? ”

"That's why I said it's cheap!" Rose smiled proudly: "You can't even imagine the production method of this thing, as long as you carve the alchemy magic array on a tablet, and then grind the white magic crystal into powder and pile it on the magic array, and then input a small amount of magic power to activate it." Woma and they have specially built an assembly line in Steel City, and one such assembly line can produce more than 100 per minute, which is just like printing newspapers, and the fast eyes can't keep up. Moreover, this assembly line can be operated by only two NPCs, and most of the production cost is transportation costs, and the pure manufacturing cost is less than ten silver coins per crystal ball. ”

"And what about the price of the efficient one?"

"The price of the high-efficiency type is slightly higher, and the manufacturing cost is **10 according to the capacity."

"Gold?"

"No, it's crystal coins."

"The efficiency has only increased a little, why is the price so much more?"

Rose also said with some frustration: "The high-efficiency post-production zuò and the ordinary type are actually the same, and the extra costs are in the early stage. The ordinary type only needs to grind the scrapped white magic spar into coarse powder and then add it according to the required weight, but the high-efficiency type must use a high-grade crusher to beat the coarse powder into a fine powder, and add a trace amount of pearl powder. That high-grade crusher doesn't cost a lot of money, and the cost is mainly on pearl powder. Although the amount added is not very large, pearls are not rotten grass after all, and buying pearls in large quantities will definitely increase the cost. ”

"Wait a minute." I suddenly noticed an important point. "You said that the high-efficiency crystal ball needs to be crushed with pearl powder and thoroughly, so can I think that as long as the crushing is as fine as possible, and more pearl powder is added, the conversion rate can continue to be improved?"

"It can be changed, but it's not unlimited. Increasing the amount of pearl powder can indeed increase the conversion efficiency, but when the proportion of pearl powder reaches one thousandth of the scrapped white magic crystal powder, it is the upper limit, and the conversion rate can be increased to twelve to one slightly higher, which can be said to be very weak. If you continue to increase the proportion of pearl powder, the conversion rate will not only not increase but also decrease, or even fail to complete the conversion. ”

"Is there another way to increase conversions?"

"Of course." Rose said, "Just add some red magic crystal powder." However, the proportion requirements are very large, and the Red Magic Crystal does not exist to be scrapped, which itself is equivalent to consumable production, and in the end, if it is converted, the cost price of a crystal ball may rise to more than 30 crystal coins, and the conversion rate is only eight to one. ”

I thought for a moment and said, "No, this model should still be valuable." Although it is a bit cost-effective to equip it for ordinary players, it is definitely worth using for elite personnel, and as for those regular versions, the price difference between different capacities is not big anyway, and it is completely unnecessary to produce three capacity levels. In this way, you go back and inform Walmart and produce like this in the future. The normal conversion rate only produces 100,000 mana and 1,000 mana, and after it is produced, each member of our guild will be allocated a 100,000 capacity. The high-efficiency type only produces 10,000 mana points, and the members of the guild can use the allotted ordinary type to make up a little more money and guild contribution points for exchange, and you can buy a few more if you want, but the price and guild contribution point consumption should be increased, and one person is limited to buying up to three. In addition, the special enhanced version is also produced, giving ten to each guild with which we have a good relationship, and the members of the guild can exchange it with guild contribution points, but no money, and the contribution points can be slightly higher. ”

"What about the regular version of the low-capacity type?"

"To the takeaway. Guilds that have good relations with us will give them a discounted price, and rival guilds will let them buy them on the black market. As for this pricing...... It's just twenty crystals a piece. The relationship guild will give them a ninety-fifty percent discount, and irons like the Iron Cross Army, the Northern Alliance, and the Bloody Alliance can consider an eighty-five discount. ”

"No problem, I'll do it."

"Oh yes, that efficient version of the 10,000-capacity will take a hundred pieces out for auction every week, and the reserve price will be one hundred crystal coins. Hehe, this is a great profit! ”

"You only sell twenty crystal coins for more than a dozen silver coins, how can there be a million profits? But this price is really black enough, and we can make a big profit this time. ”

Rose is worthy of being the housekeeper of our Frost Rose Alliance, and she has never been the queen of making money. However, the price I opened this time is indeed not low, and with that auction, I am estimated to make a lot of money. Besides, our costs are almost negligible at the selling price, so what else is there to be picky about such a cost-effective business?

As soon as we heard the sound, I knew that the shell was flying directly towards us, and I quickly stretched out my wings to wrap the whole rose in it, and then I heard a boom, and the two of us were surrounded by a fireball in an instant. However, as soon as the fireball rose, my huge pair of wings blew out all the remaining flames, and we were not harmed.

"Damn the Russians, it's been almost half an hour since this shelling, why haven't you seen them come up?"

It's not that I'm in a hurry, it's that the Russians are really super slow to attack. It's been at least forty minutes since the Frozen Banshee ordered the whole army to advance, otherwise I'd be impatient to discuss the idle things in the guild with Rose and King Chuang. However, the Russians are not in a hurry at all, although their army has been advancing, but the speed is slow, even a turtle should have climbed to our position for such a long time, but the Russians' forward is still hundreds of meters away from our troops, and the speed of a snail is probably no more than that. However, although their troops advanced slowly, their artillery bombardment was fierce and terrifying. From the beginning of the entire Russian invasion corps to the present, at least more than 100,000 shells have fallen on our positions, and many of them are magic crystal steam shells, not to mention the power, and the density is also terrifying. At first, we thought that the Russians were preparing for artillery fire, but who knew that they would fight for half an hour without stopping. If it weren't for the fact that our side was also prepared to resist the shelling, it is estimated that there would have been no living people on our positions for so long.

"How long do you think it's going to take them to make contact with us at this rate?" Red Moon, who had just arrived at the front line, asked, looking at the craters scattered around her.

"I think the Russians are scared." I pointed to the front line of the Russian army in front and said, "Looking at their expressions, it is clear that they are afraid. While their leadership knew that the battle was bound to take a huge cost, the rank-and-file members below clearly didn't fully understand their thoughts. Those people didn't want to fight us at all, and although they didn't disobey the order, they were very reluctant to come up and die, which is why the pace of advance was so slow. But then again, what about our artillery group? How can we just watch people throw cannonballs at our heads? ”

Hearing my words, Hongyue asked in surprise, "The artillery groups are all waiting for an ambush on the other side of the Yellow River." Didn't you make the plan yourself? How don't you know? ”

"Ambush? Please, even if you need artillery for an ambush, you might as well leave me a few artillery groups! You see, now, there are no casualties at all in the advance of the Russians, they can advance as much as they want, if our shelling density is half that of the Russians, I think they will dare to go forward like this! ”

"So what now?" Hongyue said a little nerve-wracking: "The artillery group is already in place, at this time, I'm afraid that if you can't hit a few shells after crossing the river, you will have to pull it back, it doesn't seem to be a good deal?" ”

Hearing Hongyue's words, Rose suddenly turned to look at me and said, "Husband, isn't your trumpet a strategic mage?" Some of us have advanced players here, just bombard them with strategic spells. ”

"That's right." I patted my head and took out the communicator and said, "God of War, help me connect all our elites on the battlefield." ”

"It's connected."

"Attention all, I am President Purple Sun. The damn polar bears across from us seemed to scare us, and it took us less than 500 meters to advance in half a day, and at this speed, it is estimated that it will be tomorrow when the two sides engage. I don't want to wait for them to crawl slowly, so I want to give them some motivation. Now pay attention to listen, all personnel immediately lined up, melee personnel formed a defensive line on the front line, crossbowmen interspersed into the defense line to assist, and the specific arrangement was at the disposal of the military god. Finally, all the mages who know how to use strategic spells will gather me behind the line of defense, so that the greedy polar bears can see our guild's unique strategic spells, and give them a gift that they will never forget. Now everybody is moving for me. ”

As soon as my order was given, the frontal defense line that our guild was responsible for immediately became a mess, but this chaos only looked chaotic, in fact, everyone knew what they were going to do, and they were not running around without a purpose, so they just looked a little chaotic.

Soon, in this all-army run, our new line of defense gradually took shape. The fish scale formation, which was originally based on a seven-person combat team, instantly turned into a horizontal formation, and the front row was all main tank fighters wearing heavy plate armor, followed by high-sensitivity fighters and balanced combatants, and finally a row of shooters. Although this kind of defense line has no attack power, its defense ability is definitely the strongest, and our front is not composed of ordinary players.

Everyone on this line of defense is the elite of our guild, and almost everyone is above the level of nine hundred and ninety, and among them, there are even many of them who are more than one thousand levels. It is no exaggeration to say that in terms of individual combat strength, this is already the strongest army in the world, and it is simply a dream to break through its defense line head-on without paying more than ten times the casualties.

But...... Although the front line of defense looks scary, the real danger is not actually the line of defense, after all, no matter how strong the line of defense is, it is also a line of defense, and if you don't provoke it, the line of defense itself will not be able to produce lethality. But behind this line of defense, the magic circle of a large group of mages is no joke.

Although Zero is not the first online game to put forward the idea of strategic spells, it is the most complete in the development and evolution of strategic spells, not only has a large and complete power calculation system, but also has a spell development system designed specifically for large guilds. As long as your guild has enough capital and technical strength, you can develop special strategic spells suitable for your guild according to the characteristics of your guild. This kind of strategic spell can be an offensive spell, a defensive spell, or even a support spell, as long as you can think of it, you can design and develop it through the guò development system, but the more demanding it is, the more difficult it is to research.

As the richest and most technologically powerful guild in the world, we of the Frost Rose Alliance will naturally not be left behind in the study of strategic spells. In fact, our guild even has a large group of full-time players who are responsible for developing strategic spells, and because our guild has gathered a large number of veteran technical magic masters like Jiaha**, the technical level in magic science is definitely a big step ahead of other guilds.

Under the coordination of me and the god of war, the mages on our side quickly moved to the designated position, and as everyone stood in their place, a huge magic array composed of people gradually appeared on the battlefield.

This strategy spell is so powerful that it is relatively demanding. First of all, this precise position is very particular, and everyone involved in the release of the spell must stand in the corresponding position, and clearly know which part they belong to and what needs to be done. This process is a bit like the kind of performance at the opening ceremony of the sports meeting, where the whole pattern or text is composed of people one by one, as long as one person stands in the wrong position, the pattern will be distorted or even completely confused. Compared to the kind of performance at the opening ceremony, strategic spells have stricter requirements for positioning, as long as one person stands in the wrong position during the entire spell release process, the spell will fail in vain time and magic, and the magic will blow up all the participants together.

Just because strategic spells are too demanding on positioning, most of the guild's strategic spells are generally used in small formations. There are actually six versions of each strategic spell. The first version is a single-player version of a strategic spell, but this spell generally doesn't appear on the battlefield, because it's used to test the feasibility and ultimate power of strategic spells, and it doesn't really have much practical value. In addition to the first edition, the remaining five versions of strategic spells are Micro, Small, Medium, Large, and Mega. These five models are actually useful strategic spells, and each strategy spell will have all six versions of it from the day it was researched.

In fact, as you can see from the name, the difference between different versions of strategic spells is in the volume. The small ones have little power and low requirements, while the large ones have high power and the requirements are relatively high. Under normal circumstances, guilds will only use the micro and small levels of strategic spells, as these two levels are safer.

The miniature version of a strategic spell usually requires only seven or eight people to cast spells in combination, and it does not need to be a core strategic mage, which means that it only takes seven or eight mages to move together to cast a spell. In addition, because of the small number of people, it is relatively easy to stand, and the miniature version of the strategy spell itself has a high error tolerance, so even if someone stands a little crooked, it is not a big deal.

Compared to the miniature version, the miniature version of the strategy spell requires a little more personnel. In general, small strategic spells require a group of more than thirty mages to cast spells, and at least one strategic mage is required to act as the core. In addition, from this level onwards, the requirements for strategic spells will become very strict, so most guilds will first send people to draw magic arrays on the ground, and then have personnel stand up according to the markings on the ground. The advantage of this is that it is not easy to make mistakes, and the disadvantage is that it takes a lot of time to draw the magic circle in advance. However, considering that strategic spells themselves do not belong to the category of rapid mobile strikes, it is barely acceptable to delay a little longer.

The Medium version of strategic spells is naturally more demanding than the previous two versions. This version of a strategic spell is generally a hundred-player scale, and depending on the type of spell, multiple strategic spells may be required to act as nodes, and then one of the most powerful strategic mages will act as a guide. Of course, this kind of strategic spell arrangement on a scale of 100 people also needs to draw lines in advance to make the mages stand up, otherwise so many people will definitely make mistakes.

For the average guild, the above three are the limits of what they can use. First, most guilds don't have so many mages to complete larger strategic spells, and secondly, they can't guarantee accuracy, after all, the large and super versions of strategic spells don't rely on drawing magic arrays on the ground to ensure that the position is not wrong, unless there is a special method, the general guild can't afford to play this kind of thing.

But...... Unfortunately for the Russian Expeditionary Force, we at the Frost Rose League have exactly the kind of super strategic spells that we can play.
