Isabella and the others immediately frown, that thing is in the mystical realm grade 6 peak and on top of that it clearly carries an artifact of good quality with it, in the end she can only sigh and directly retreat 5 fragmented formations, after all this left flank has piled up about 15 fragmented formations, 6 of the troops and 9 of those carried by Isabella and the twins.
Shortly after the march of the undead resumes, but with an important change, this time the icy figure raises and begins to recite an area spell, while holding what seems to be an amplification artifact focusing on the yellowish skeletons, with it a huge magic circle appears covering them all.
After that the yellow skeletons accelerate their march at a remarkable speed for them, it is obvious that they want to use them as cannon fodder to protect other stronger troops, even the undead warriors and ranged attackers retreat behind the tide.
In this moment then Ada crouches to say: "Young lady, this army is commanded by a lesser Lich, I can bring it down with one shot from my rifle but… it is very well defended, we would have to get rid of all the trash around it."
Isabella suddenly opens her eyes and then smiles, although Feicui Long intends to give all his troops growth-type artifacts, he does not have enough materials, luckily he buys some for one half and the other half who come from the Skylion family army already possess their own… something that is totally positive in this moment, since although not all weapons are made of sky platinum like Feicui Long's.
They are made of sky steel, another metal with the sky attribute and therefore particularly good for killing beings of the demon clan, infernal clan and of the undead clan, but better yet they can kill a lesser Lich even without having to destroy its phylactery.
Shortly after the repositioned undead resume the ranged attacks, arrows, bolts, energy shots and elemental attacks of all kinds head to the first formation causing it to shake for a few seconds.
Isabella calmly nods with her head and says: "Then let's give a welcome to this pile of undead trash."
Then she looks at the twins and says: "Take out the talismans and attack scrolls focused on area damage, we must not skimp to destroy all this cannon fodder, still keep a few."
She, Callista, Melina take out several talismans and scrolls and injecting energy into them several attacks begin to activate, from great balls of fire, to great cuts of wind, spheres of light, among others.
But the Lich who leads this group of undead is not an idiot, it snaps those skeletal fingers and with it a great spell appears from an ignored direction and apparently the spell is already very advanced since it has taken complete form a great ice spear heads quickly where Isabella and the twins are to try to interrupt them.
However it is useless, because despite the great spell the three continue activating the talismans and scrolls…
When finally the spell impacts it explodes into hundreds of icy fragments without harming Isabella and the twins, but it does strongly shake the barrier of that formation, this time surprising her so that her expression changes to a worried one and she says a little scared: "That attack is already at the level of the ascending realm, we need to find where those damn undead mages are hiding."
While all the attacks of the scrolls and talismans explode on the enemy troops killing many yellow skeletons and even higher quality troops, she decides to bring out her wind peregrine falcon, she gives the order to track the mages, she does not worry that the enemy has flying troops, since her falcon by itself is difficult to follow in its speed even for other specialized, now for an undead it is even more difficult.
...
While this happens the other troops in their barricades who are a little closer to the first two barriers, are attacking from a distance, at least those who can, when finally the undead begin to pour like an uncorked bottle jumping at the formations no matter their life or death.
In those moments the grotesque sound of crushed bones, burning flesh and more is heard on the battlefield, while the allied contracted creatures stationed at the edge of the second formation begin to prepare for close combat, while those of distance at the side of their mistresses, also attack the enemies.
Callista in turn takes out the bow made by her uncle, both she and her sister have a melee weapon and a ranged one, after all, Feicui Long has taught them both types of combat and besides, it is quite stupid to carry only a ranged weapon to the battlefield, even the poorest army would always carry a spare weapon to defend themselves.
She with this strange bow, made of materials that her uncle buys at great price shoots without hesitation at any important threat, but especially other archers and elementalists.
On the other hand Melina prefers the energy rifle, it has more range and she can hide behind her contracted creatures specialized in close combat, the two undead alpha lizardmen with smooth scales, carry great shields and spears, all sixth grade artifacts, her rock golem protects her from behind.
Her attack on the other hand is directed at the more heavily defended warriors, most of whom do not even have pseudo artifact level equipment, they are poor mortal things, so her rifle pierces them like butter especially empowered by those rare materials very similar to those of her sister's bow.
With it the battle is clearly tilted, but then the lesser Lich, yes the Lich, because just in a moment an irritated clearly feminine voice comes from that sack of bones saying: "These damn flies are stronger than I thought."
Then she points with her open hand and says: "I have no choice but to use that card, go my precious toys!"
After that several enormous birds of about 3 to 5 meters appear in the air, at the same time that from the ground numerous undead beasts of different sizes come out, particularly standing out the largest ones that have the shape of bears, tigers and elephants.
Melina astonished cannot hold back a curse word despite her normally cold, calm and indifferent personality: "Damn it, there are many mystical realms among those beasts!"
Callista on the other side looking seriously makes a quick calculation and says: "I think in total, there are about 100 mystical realms grade 1, 50 grade 2, 25 grade 3, 10 grade 4, 5 of grade 5 and 3 of grade 6, this is problematic, their attacks could weaken the barriers faster than all this cannon fodder."
But as if not wanting to give them time to take countermeasures the gigantic birds begin to unleash their abilities, either sending feathers or launching breaths or other types of energetic abilities, under this scourge and the innumerable yellow skeletons that remain more or less about a thousand and something, the first 3 formations tremble strongly, almost crying under this torment.
...
Isabella who just discovers the location of the mages thanks to her falcon, looks at the sky with a frown, she still has some talismans and area attack scrolls, but now she has to decide, to face the undead energy beasts or to eliminate the undead.
Then she remembers something that Feicui Long gave her, among the many things to protect herself, there was an insignificant thing that many would ignore…
A talisman… the talisman of energy beasts bait, perfect to attract beasts and they were next to the giant acid ants, if they used it correctly they could perhaps eliminate at least a large part of the cannon fodder.
The problem is…
That someone must infiltrate the territory of the ants and on top of that be able to return, to plant the talisman in the enemy side…
Unfortunately she is not good at stealth and it seems that none here is, still she cannot surrender nor send someone to a certain death, she would have to risk herself if they want to get out of this.
Then deciding and gathering courage she gives Ada half of her remaining area attack talismans and gives her an order: "Ada, use them to eliminate the mages they are the greatest threat of all, they are in that direction, there are quite a few almost 50, so you have to make sure to kill them all or almost all."
After saying that, Isabella running through the 5 formations that protect the right flank uses a talisman of light feet, steps of the spirit and at the same time uses steps of the sky lion and at great speed she goes deep into the forest of the acid ants.
...
While this happens Ada, without wasting time activates the scrolls and with those devastating attacks the lesser Lich can only watch as her body of hidden mages is destroyed just like that.
Activating her artifact angry she shouts: "DAMN ANNOYING BUGS, HOW DARE YOU DESTROY MY PRECIOUS TOYS!"
Subsequently she begins to cast another area spell, but this time the target are the undead beasts, once it is completed all begin to act more fiercely, while the eyes illuminated in red or by the blue fire of the souls ignite with a sinister glow, now the first formations tremble even more, even the sound of cracks appearing can be heard.
