With the appearance of this auxiliary magic called 'Marmasville', these 24 groups of magic circles began to form a 'conduit' between them and the 10-meter magic in the air. Black tentacles spawn from the upper edge of the circle and rise into the sky, resting on a huge magic circle in the air. Then, a flash of black-purple light was channelled from these tentacles into a huge magic array in the air.

Countless black-purple tentacles wrapped the magic circle in the air, as beautiful as coral, and the sporadic flashing dark purple light spots on it were also quite beautiful.

The magic array that absorbed the magic power rippled from the edges in layers of black ripples. These ripples converged in reverse to the center of the magic array in the air, and then, in the center of this magic array, a small black crystal actually appeared. And it has grown over time.

This black crystal is only a 'temporary mana crystal' that is temporarily used to store mana, and if the caster stops casting, the mana crystal will shatter and the large amount of dark elemental mana inside will disappear.

So what this undead boss did was very simple, which was to collect the magic that could not be immediately infused into the Dark Crystal, wait for this wave of mana to end, and then slowly inject it into the Dark Crystal.

Yes, the ore used by demons to store their mana is crystal ore, but the crystal ore they use is often very large, so large that it doesn't look like it was naturally generated.

Now, moving on to that little magic crystal. The height of this small black crystal quickly increased from 3 centimeters to 12 centimeters, and then 48 centimeters, as waves of black ripples poured into it.

Fortunately, this room is tall and big enough, otherwise it would not be a ceiling.

The Mana Storage Center was originally an extremely dim room, however, due to the unexplained explosion of dark elemental magic in Pengmai City, all the magic arrays in the room bloomed with dazzling white light due to overload.

……

Time slipped by second.

At the 7th second, a skeleton demon was blown away by the rampaging magic and stopped by a black magic circle. Immediately, a skeleton mage stepped forward and took over the man's job.

And the demon that was shocked was disintegrated by the black magic array in the next second. The body turned into smoke and dust, and was compressed by the circle to form a crystal. The crystals then flew into the mouth of the skeleton mage who had taken over the job.

The new demon sneered softly as he bit and swallowed without hesitation.

Demons are such beings, whether they are humans or other races, they will kill them. Even if they are their own people, as long as the 'superior' demon who manages them allows it, they will not show mercy.

This kind of thing, in the next tens of seconds, happened no less than ten times one after another.

In the end, with the unremitting efforts of dozens of demons, the magic rage that had been maintained for nearly a minute finally came to an end.

The rotation speed of the 24 magic arrays had dropped significantly, the shaking had completely disappeared, and the light had dimmed a lot. The light of the dark elements inside the tentacles that stretched out from the edge of the magic group also dimmed, and it seemed as if it had stopped transmitting mana, but in fact, it was only because the amount had become smaller, so it was difficult to see clearly.

The black ripples on the magic array in the air disappeared completely. The black magic crystals on it have also increased from 1 at the beginning to 5. However, due to the fact that the magic array obstructs the vision, the undead boss below does not know about the 'temporary magic crystal' on the magic array.

The blinding white light of the upper circle on the ground also disappeared, turning back to a chilling dark purple. The whole room was back in darkness.

"Whew......" the undead boss breathed a sigh of relief, "It's finally stopped, everyone obeys the order, and begins to pour into the magic pool in reverse."

"Yes!" x24

「Lio-Siip

i-Fa-DeLize

With a hoarse spell came out of the undead boss's mouth.

On the ground, the outer ring of the magic array in front of the 24 people instantly split into two layers, one black and one purple. The 10-meter magic array in the air also appeared with the same two outer rings.

Immediately, those tentacles that had originally injected magic power into the magic array in the air began to absorb magic power from the magic array in the air in reverse.

Black ripples appeared on the magic array in the air again, but this time the angle and direction of the ripples were the opposite of before.

Strands of dark elemental magic were released from the 'Temporary Magic Crystal', flowing down the ripples, flowing into the tentacle conduits, and returning to the 24 magic arrays. These magic arrays inject magic power into the ground, and the large magic arrays on the ground merge into the dark crystal in the center. The faint purple ground magic array that had just returned to normal immediately lit up with white light again, but the brightness was obviously not as bright as before.

The 'mana return' process lasted a full 3 minutes.

In the process, there were no accidents, and no demons were replaced by their own kind.

After the temporary magic crystal in the air disappeared, the ten-meter large magic array also disappeared, and at the same time, the outer ring of the 24 groups of magic arrays also disappeared. Only the usual 3-layer magic array remains.

Everything was calm again, and the room was dark again.

The Undead Boss, who had been holding up his left hand, finally let go of his left hand.

"Whew, it's finally over." The Undead Boss sighed secretly in his heart, and then continued to think happily: "Now, let me see how much I have saved." ”

Thinking so, it raised its hand and cast a very special spell on the dark crystal floating in the air in front of it.

A black feather magic array with obvious asymmetry and a very chaotic pattern appeared, and in the middle there was an area displaying numbers, and the numbers on it were growing at a crazy high speed.

1423-7425-24546-57483-80861-124003……

The number grew rapidly from 4 to 5 digits, and in the next second it broke through to 6 digits.

"If I'm not mistaken, it seems to be 160,000. Now, it's four or five hundred thousand. Thinking happily in his heart, a bone-chilling laugh came out of his mouth: "Hehehehe"

This is not the first time that this undead boss has experienced a magic rampage, so he is naturally sure in his heart.

(The magic absorption circle in the sky above Pengmai City can not only absorb the magic of the dark element, but also transform negative emotions.) Of course, this circle is usually built under the city of Pengmai. It's just that this year it was put into the air, and in order to increase the sense of depression among the residents of Pengmai City, it was deliberately supplemented by black clouds. )

Just as this person was laughing, the number on the Black Feather Magic Array, as it expected, had advanced to 400,000. But it's still growing fast.

208344-324100-401092……

"Hehe, is it really 500,000?" The demon continued to rejoice.

485574-507912-579214……

"Huh?!" Seeing that the values did not stop the demon that was still flying rapidly, he immediately let out a sound of shock. (Since there is no skin, only skeletons remain, so there is no way to see this person's expression)

However, at this moment, the numbers on the magic array are still soaring rapidly.

600,000??

700,000??

80？ 90？ Hundred?!
