"Can this formation be arranged by someone other than you" Dongfang Xiao still did not give up hope, although most of the soldiers in the barracks were relatively low-strength soldiers, but there were also a few magicians among the officers, but I don't know if they had the ability to arrange the formation.

"It's doable, it's doable." The necromancer nodded slightly, "It's just that the difficulty of this formation is not low, at least it must meet the requirements of a junior magician to be able to arrange this formation, and this formation belongs to the formation of necromancer, so naturally it is best to have a necromancer to arrange it, in addition, a person with a very strong dark power like Lord Dongfang can also do it, as for the others, there is nothing they can do." ”

Dongfang Xiao's heart sank, although there were also a few magicians in the barracks, most of them were the strength of magician apprentices, and none of them cultivated the dark attribute, let alone the rarer necromancers.

"Can you continue the duration of the magic, or increase the number of times the magic is actually used?"

Since the idea of letting the rest of the barracks set up the magic array didn't work, I just got up. The supplier urinate and turns to other possibilities.

"This," the necromancer hesitated for a moment, then nodded, "This idea is theoretically feasible, but it is very troublesome to operate in practice. ”

"What kind of trouble," Dongfang Xiao asked.

"In fact, the principle of this magic is very simple, it is just the use of the dark power condensed in the bones of the undead, but the dark power condensed in the bones is very limited, and each time the formation is activated, a large amount of dark power needs to be consumed, and the maintenance of the formation also needs to be able to ah, the power is constantly maintained, so each time the formation is activated, it can only last for one day, and after a day, the power in these bones is completely evacuated, and the formation also collapses because of the depletion of power, so it has to be rearranged, theoretically speakingAs long as you can find something that contains powerful dark power, you should be able to maintain the operation of this formation. ”

"Contains a powerful dark force"

Dongfang Xiao fell into deep thought, most of the materials they collected last time were the materials on the E-level undead, if they wanted to seek a more powerful dark power, I am afraid they could only fight the idea of D-level undead creatures, but this level of undead creatures is already very difficult to find outside the Undead Wasteland, and most of the undead creatures of this level already have their own wisdom, and it is even more difficult to deal with them, even if everyone can deal with them, where to find so many D-level undead creatures

"Do you want to go to the general for help?"

Dongfang Xiao instantly denied his idea, he didn't want to owe favors to others just casually, besides, it would take a lot of time to go back and forth to the City of the Dead, and it would be too late in terms of time.

"By the way, see if the materials in your collection meet the requirements."

Dongfang Xiao remembered the dragon man's eye that he took out last time, which contained extremely powerful light attribute magic, and maybe among the materials he collected, there were also things that contained strong dark power.

"Found it"

With Dongfang Xiao's consciousness searching, he really found something suitable.

A black-purple crystal appeared in Dongfang Xiao's hand, and from that crystal, an extremely powerful dark magic emanated.

"What is this" The black-purple crystal attracted the attention of the necromancer as soon as it appeared, and he could clearly feel that this crystal had extremely powerful dark magic.

Dongfang Xiao smiled, this thing is called "Evil Crystal", which belongs to the product of the Heavenly Veil Giant Beast, especially in the purgatory, there are many dark elves in the purgatory, these Cermytek always like to be with undead creatures such as zombies and zombies, and the evil crystallization is also the condensation of Cermytek's energy.

"There is no problem, according to the dark magic contained in this crystal, at most four pieces, it is enough to maintain the operation of the method, plus the bones of some undead creatures, it is completely possible to open or close the formation at any time, even if the formation is continuously operated for a week, there is no problem at all."

Dongfang Xiao sighed, reassuring him that there were still more than a hundred evil crystals on his body, and four were not a problem for him at all.

Dongfang Xiao took out a few evil crystals from the space bag and threw them to the necromancer, the necromancer saw that Dongfang Xiao actually took out several such crystals again, and hurriedly caught them, but the necromancer who caught the evil crystals was a little stunned, Dongfang Xiao gave him not 4 evil crystals, but a full 10.

"This thing should be of great benefit to your cultivation, except for the four pieces used for the operation of the method, I will give the rest to you."

"Thank you, Lord Dongfang" The necromancer's face was full of ecstasy, after seeing this evil crystal, he wanted to say that it was impossible for him to say that he didn't want to take this thing for himself, and the powerful power of darkness and death contained in it was simply a treasure for a necromancer like him.

Dongfang Xiao smiled, although this thing is said to be useful for necromancers, it is useless for him, what he cultivates is the power of ghosts and gods, so naturally he does not need to absorb the power of this thing. If you want to talk about this evil crystal, the level is quite not low, how to say that the Heavenly Veil Behemoth's Celestial Beast has reached the C level, and the preciousness of these materials has naturally reached the C level, if you can completely absorb the energy in it, presumably the strength of the necromancer will reach the C level intermediate level, there must be no problem.

After receiving Dongfang Xiao's material assistance, the necromancer began to set up his formation non-stop, I have to say that his attainments in the formation have a certain level, in less than a day, the new formation was rearranged by him, and the control of this formation is also very simple, even people without dark power can easily control it. And Dongfang Xiao, who saw this, was finally relieved, now even if the soldiers here did not withdraw, they no longer had to worry about the threat of those undead creatures, this formation was enough to resist those low-level undead creatures who had no wisdom, Dongfang Xiao and the others were able to leave with confidence when they saw that the formation was successfully set up.
