The black crystal was about the size of a fist, and at first glance it was round, but it was actually a polyhedron, somewhat similar to a football, and its material was translucent, looking like amber, through which you could see the candle flames dancing in the room.

At first glance, it seemed very ordinary, just a black hedron, something that could be found everywhere in those gem shops.

The only thing that is special is that under close perception, you can clearly feel a trace of darkness emanating from the crystal.

This aura was very faint, and if it weren't for Link's extremely keen perception and the fact that he was so close, he wouldn't have been able to perceive it at all.

After looking at it carefully for a while, item information popped up in the field of vision.

Intermediate Dominic Crystal (alias: Universal Crystal)

Quality: Immaculate

Level: 5

Purpose: Used to store power, which can be elemental, mystical power, transformation field, magic energy, etc.

Current Status: Dark Force (25% Charge)

Seeing this news, Link's heart jumped suddenly, and then he was overjoyed!

Dominic crystal, a strange crystal invented by a genius alchemist named Dominque a thousand years ago, it has an extremely huge effect and is extremely complex to refine, so it is very expensive, Link estimates that this flawless Dominque crystal in his hand, although it is only level 5, is worth at least 8,000 gold coins, and it is still priceless.

It's really a lot of money!

For a magician, this thing is very, very powerful.

For example, Link, when he releases the glass orb, the shortest time is currently 0.04 seconds, and in this time, less than 0.01 seconds is the time that Link himself uses to build the magical structure, and the other 0.03 seconds is the time when the elements converge.

This is true of glass orbs, let alone whistles, where at least 0.15 seconds of the 0.2 second cast time is spent waiting for the elementals to converge.

But with this Dominque crystal, as long as Link stores elements in it, such as the fire element, then when he releases the fire magic, this time is almost negligible, then the time for him to release the glass bead is estimated to only take a little more than 0.01 seconds, and the whistle, it is estimated that it only takes 0.05 seconds, and even the fire element magic of level 3 and 4 may break through the 1 second mark.

That's not all, if you store magic energy in it, then Link's magic energy endurance will immediately increase a lot, and the embarrassment of overstretched magic energy that appeared before will be greatly improved!

All in all, Domingue Crystal is the god-level equipment that every magician dreams of!

However, this crystal cannot be used directly, and it has one last problem, that is, this crystal is full of dark power imported by Morpheus, and he has to find a way to exorcise it.

'Looking for a pastor?' ’

This was the first thought that came to Link's mind, in the previous life game, he had also obtained this kind of dark Dominque crystal, which was usually expelled by a priest.

But that's the game, here's the reality. Such a rare treasure, looking for a priest? It is estimated that everyone will soon know that it is a question of whether he can keep this crystal or not.

The difference between the game and reality is that the game is essentially a world with abundant materials and extremely protective of the rights and interests of players.

In the real Faroman Continent, there is a shortage of materials, especially spell casting materials, otherwise the price of various magic materials would not be so high.

So Link vetoed the decision in the first place.

"Then you can only use the soil method, although the time is relatively long, but it is better that there are no sequelae."

In the previous game, some magicians were reluctant to spend this purification fee, and they did not have an alchemy room to use, so they thought of a 'living water purification method'. ’

The specific method is that the magician puts the dark Dominque crystal in the living water such as streams, rivers, mountain streams, etc., under the guidance of the water element, the dark power in the Dominque crystal will be released faster, such as the level 5 Dominque crystal in Link's hand, which should store the dark power that can release at least one level 5 magic, then it will take nearly a month to purify, if it is 25% completion, then ten days will be about the same.

However, there is a problem with this method, releasing the power of darkness in the river is not inferior to poisoning the river, think about it, the dark power contained in a level 5 magic, if converted into the fire element, the power of the explosion is definitely no less than a cloudburst bomb!

Unleash such a huge amount of dark power in a river, and the creatures in that river will definitely die, and if anyone drinks the water in the river, they will also get seriously ill.

In short, this method is very immoral.

In the game of his previous life, Link had received a mission called 'Teach the Shameless Magician!' ’。 One of the shameless magicians did such a bad thing, so that all the crops in the farmland next to a small village below the stream died, all the water could not be drunk, and even the ancestral graves of those who lacked virtue emitted black smoke.

Link certainly can't do that, he has a way to improve.

But now that the night is getting late, Link is just healing from his injuries, and it is not advisable to stay up late, after releasing another elemental healing for himself, Link puts away the Domingue crystal and falls asleep.

Nothing was said all night.

Early the next morning, Link's body had basically recovered, he had received the elemental essence supplemented by the elemental healing, and he had been fully rested, he felt that he was in good spirits, and he seemed to have gained a little weight.

After breakfast, Ark, Lucy, and Gridan went out to handle the loot, leaving Link alone in the mercenary yard.

He went alone to the attic above his room, and the floor of the attic was also made of stone, very strong, and above it was the roof, which had a glass skylight, and the sun was shining through it.

Link began to cast a spell, using the magic spell "Shaping", and cut out a large water tank from the stone floor, the mouth of which was facing the skylight of the roof, no, to be exact, almost connected, and the water tank could not be seen from the attic.

Link then fills the tank with clean water.

The tank was large, cylindrical, nearly one and a half meters high and two meters in diameter, and Link had filled it with four or five tons of water to almost fill it, and if he hadn't used shapings to reinforce the floor of the attic, the building would probably have collapsed.

After adding the water, Link tossed the Dominic Crystal into the tank, and then he began the final step.

He climbed to the roof, to the attic window, and once again used the shaping technique on the window, so that the skylight and the surrounding structure were completely integrated and became impossible to open, in order to prevent someone from stealing his crystal silently.

Then, Link continued to use shaping to transform the structure of the skylight translucent crystal, and after some complicated adjustments, the structure of the crystal changed dramatically, from the outside, everything was normal, but inside it was actually a set of delicate light and shadow structures.

Sunlight from any angle is focused by this intricate crystal structure, which is then transmitted onto the dark Dominque crystal inside the tank.

Sunlight is the greatest brilliance in the world, can restrain all the dark breath, the sun shines on the Dominque crystal, can be the first time to eliminate the dark breath diffused on the crystal, so that it will not be detected by the outside world, but also to ensure that the concentration of the dark breath in the water in the tank is always at a very low level, which plays the same effect as living water.

Fearing that the sun would not be enough, Link used shapings to open an additional large skylight in the attic and direct the light from it to the water tank, which ensures that even on cloudy days when the sun is not very abundant, the light can have a sufficient purifying effect.

As for the night, it doesn't matter, the dark power that overflows from the Dark Dominque Crystal will be absorbed by the clear water first, until the clear water is saturated, and then it will start to overflow outward.

And one night is obviously not enough to saturate the clear water, so the outside world will not feel any abnormal dark aura.

The weather in Gwent Forest is good today, the sun is strong, standing in the attic, Link carefully felt the efficiency of the purification, and laughed: "It is estimated that in a month, I will be able to harvest a pure Dominque crystal." ”

Although it has been a little longer, it is safe and private, and no one will notice.

He left the attic, and before leaving, he directly used the shaping technique to remove the door, and from a distance, there was only one wall left.

Anyway, this attic is on top of Link's room, and Yak and the others won't come over, so if they do this, they will completely eliminate the chance of the crystal being discovered.

It's not that Link wants to guard against Ark and the others, but there are some things about magicians, it doesn't matter if they know it or not, and if they know it, they have to worry about it, so why bother?

When I was done, it was noon.

After waiting a little longer, the three Ark also returned, they had already sold the loot in the black market in Riverdale, and harvested 2,500 gold coins, an additional 200, and they were all smiling when they ate lunch.

Seeing their happy appearance, Link was also quite happy.

After eating, Link took out the letter he had found in the syndicate's lair and said, "This is the correspondence between the black-robed magician who attacked us in the Valley of Red Leaves that day and his friend, and it says that the black-robed magician is a dark elf named Philidia, and his friend lives in a place in the Gulf of the Howling Wind. Do you know this place? ”

Several people recalled, and then they all shook their heads.

However, Ark said: "Recently, there have been a few new faces in the town, mostly mercenaries from the north to the south, but there are also a few bards who have traveled north and south, maybe they know this place. I'll inquire in the afternoon. ”

"yes, okay." Link nodded, and then said, "I'm going to study magic at the East Valley Academy of Magic tomorrow, and I shouldn't be able to come out on a regular basis, so if you have anything, just ask Lucy to write to me." And, Ark, Gridan, you two are going to start learning to read. ”

Of the three, Lucy is literate and good at arithmetic, so she can become the butler of the mercenary team.

"Okay." Ark and Gridan replied with bitter faces.

"As for the gold coins, it is enough for me to bring the tuition fee and the extra cost of 100 gold coins. The remaining nearly 4,000 remain here. ”

"Adult" Lucy has a different opinion.

"Listen to me." Link raised his hand and pressed down, stopping Lucy's words, "I don't need to spend money at the East Valley Academy of Magic for the time being. And now, our strength is already very good in Riverdale, and Ark is a powerful warrior at level 4, and we also have the relationship of Knight Anderson as the upper rank. I think it's time to think about recruiting people and forming a mercenary group. ”

Saying this, the three of them were speechless to refute, forming a mercenary group has always been the dream of Yak and others, and now the conditions are indeed very mature.
