The sound of teleportation was heard, as a blue flash of light was shown in the middle of an unknown area, as 2 figured walked over and into the strange place that they are now residing in. These 2 are the women of ice, and they are Ganyu and Yumi. The Ice Maiden Shinobi and the Half-Adeptus are looking around in the area that they are inside of right now, and needless to say, what they are in is a very frighting place.

The area that they are in is appearing to be at the brink of eruption, as it resembles a volcano, with magma oozing all over the place, and there are bits of machinery present, seemingly assembled as clockwork and steampunk-themed machines that are used in this sort of location. And this place is also covered in red veins, like the ones found in Ebott City, although they seem to have less compared to the other locations, due to the active heat that is present in this place, but there is these odd volcanic veins connected to some of the red veins, and they seem to be activate. That must mean that nose veins are mutated enough to resist the heat.

Ganyu stepped forward, and she looks a little bit uneasy about this place, as Yumi also stepped forward, and she than spoke onto to her.

"It is obvious that Prometheus is somewhere around here. Kind of fitting, as this Dead Cell is the only one that can safely manipulate fire."

Ganyu stepped forward, as she than spoke out to Yumi.

"Yumi, you do remember how long we can be here, right? The Portable Wayport that I have used, it will not last long. We have about 30 minutes before we are forced to teleport back to Sans again, and than, it is all over."

Yumi looks at Ganyu and nodded her head, as she than spoke out to her, and she does not sound happy.

"Yes, but I thought that it lasts for 7 days."

Ganyu than spoke out.

"Not this one. The one that I am using is an imperfect version of the ones that are usually used, so the time limit is much more shorter than before."

Yumi nodded, as she than spoke out to her.

"Than we cannot waste anymore time. We need to go and try and find Prometheus, and fast."

Ganyu nodded her head, as both Yumi and Ganyu look at the location that is before their eyes, the location of where the one called Prometheus is located in. And the place, not to mention resembling a volcano, also resembles a factory of some kind. It Desmond's Yumi of Hotlands from Mount Ebott, Abyss' former home, except that it has the machine called the Core. But in this case, it resembles a factory of some kind. This made Yumi and Ganyu a little bit afraid of what they are seeing before their eyes, and yet, they are both ready to enter into the machine, and try to find him.

"Ganyu, are you ready?"

Ganyu nodded, as she gripped her Bow and made an arrow of ice appear, as she is ready to fire it, as Yumi took out her hands, and unfolded it, as she is ready to go in.

"Than there is no time to waste. Let's go in."

Ganyu nodded, as she and Yumi ran to the factory-like place, as they both leapt up and began to climb the metal walls. Luckily, this type of metal does not seem to conduct and transfer heat, so they are able to safely grab onto the metal of the walls. They kept on climbing for a pretty long time, about 2-3 minutes, but after which, they are able to reach the top of the walls, as they look to see what it is that is happening before their eyes, and what it is that they are witnessing, and it is something that they are not expecting to see at all. They thought that it is a factory of some sort, but it turns out, it is not a factory at all, it's a city. One that is larger than Ebott City itself, and the entire city, it is crawling with infected. But these infected are very different, ads they are glowing with veins that are volcanic-like cracks, and they are appearing to be made of molten rock that is glowing from magma, as Yumi spoke out

"Woah. These types of Dead Cells kid have mutated to the point that they can now weapon is and use magma to their advantage. How in the world did they manage to eliminate their weakness to heat?"

Ganyu than crouched down a little bit, as she does not want to be seen by the Infected's along with Yumi, who is also crouching down and making sure that they do not attempt to be spotted by the infected that are below their feet.

"Yumi, where would this one, Prometheus, be at?"

Yumi looked around the area that she is in, as she spoke.

"Somewhere where he would be protected and not he attacked in a place that wound be obvious to spot in. Where he wound he difficult to be seen by anyone. Possibly at the center of the city that he is in, or just hidden from plain sight, I believe so."

Ganyu nodded her head, as she than looked at the city that is before her and readies her bow and arrow. Her eyes narrowed, as she than spoke out.

"And what about these undead beings? Are they as strong as they were before when we had last fought them."

Yumi than shook her head, as she than spoke out to Ganyu.

"No, they are stronger than ever before. Now they are resistant to flames, and they seem to weaponize the heat as their own power. They misted have been exposed enough to mutate to such an extent, in that they were would use one of their greatest weaknesses into something that they can utilize into one of their greatest strengths."

Ganyu's eyes narrowed, as she felt unhappy at this, and she than spoke out.

"That is not good. That means we will have an even more difficult time defeating them."

Yumi nodded her head, as she than spoke out.

"It seems so. But we cannot waste anymore time. We need to move, before the temporary teleportation wears off. Come on, let's go."

Ganyu nodded her head, as she and Yumi than both stood up, as they than turned to a direction, and they began to jump, as high as they can, as they went from structure to structure, so that they can try and find the Dead Cell, Prometheus, quickly. But going to find him is not easy, due to the fact that he is going to try and make sure that he is not spotted. They jumped and jumped, as they looked around and all over to try and see where he is, only to find nothing. But they know that he is around this place somewhere, as they continued to leap from building to building, as they are too determined and stubborn to try and give up. Abyss, he is depending on them, he has hope that they can succeed.and try to kill it, so they are going to continue, and they won't stop until they have succeeded.

As they leapt and continued to jump and move from place to place, Ganyu turned her head, as she has felt something, due to the CELL Core granting her the ability to give her an enhanced form of hearing, and when she turned, she saw that there is a Dead Cell Hound, ready to bite Yumi's head off, it's teeth are hot and covered in flames. Thinking quickly, Ganyu grabbed onto Yumi's hand, and pulled her back, as the Hound missed, but both Yumi and Ganyu than began to fall down to the ground, as they both looked down to see that there are Dead Cells beneath them. Ganyu narrowed her eyes, as she realizes that the Hound must have wanted this to happen. Well, she is not going to give the Hound what it wants, now would she.

Ganyu focused her sight while she is in the air, along with Yumi, as she tries to position her body in a way that can aid her in this. Ganyu than gripped her bow, and she then accelerated her speed of going down to the ground, as she landed on top of a Dead Cell, killing it, as her feet are covered in Cell Energy, which destroyed it. And this is when Ganyu took the time to strike, as she then fired and launched arrows at the Dead Cells without hesitation, as the arrows hit the Dead Cells it founded and killed them. This is so she can make enough room for Yumi, who than lands next to her, as her fans are out. Than, the same Hound from before landed onto the ground in front of her, and the Hound tries to bite Yumi, only for Yumi to swing her fan and slice the head of the Hound off, which killed it instantly. This made Yumi surprised, as she did not expect a hound to look like this. But then again, this place if filled with infected, which includes the hounds. So it is not that surprising.

Than, as they looked around, they see that they are not getting surrounded by infected Dead Cells, as they began to move towards the 2 Ice Women, as Ganyu and Yumi stepped back, their weapons out, as Yumi spoke out.

"Obviously, I should have expected that we wound be forced to fight then, whether we want to or not. Ganyu, are you ready for this?"

Ganyu raised her bow and arrow, as she nodded her head.

"I am. And we shall bring them down without restraint."

Yumi nodded her head, as she raised her fans, before she than spoke out to the infected.

"Now than...for you monstrosities...Sink into the dreams of sleeping souls!"

Yumi than began her attack towards them, along with her partner, Ganyu.

Yumi suddenly launched a bunch of icicles at the Dead Cells, as they are then pierced by their sharpness. And needless to say, the CELL energy that is infused inside of the icicles is enough to destroy the CELL Core and kill the infected permanently. Than, a infected tried to bite her from the neck, only for Ganyu to duck and slice their head off, before stabbing one in the chest, killing it. But then, one of the zombies did something completely unexpected, as they spat out magma from their mouths, which made Yumi duck. She looked, as the magma melted a hole in the ground, all the way to the pool of lava that is below the city. This made Yumi the potential dangers of these Infected, if they spat around both her and Ganyu, and than they would fall down to the magma. Ganyu seems to think the same thing, because she is not going ahead to try and kill them as fast as she can, along with Yumi, who is not desperate to try and finish them off before it happens.

Ganyu dodged the infected that are rushing at her and made an ice bomb, before she then pulled her bow and arrow out and fired a bunch of ice arrows down, and at this is able to kill the Dead Cells that got to close. And at the same time, a bit more larger Dead Cells began to move forward, the Ice Bomb exploded, firing ice shrapnels all over the place, and killing the Dead Cell infected. She than used her own power, thanks to the CELL Core having increased it, as she than made an icy rain go down on top of her foes.

Ganyu looks at more of the Dead Cell infected, as she than launched more of her arrows at the Infected, as she charges them up much more frequently than ever before, in order for the arrows to make more copies of itself when she fires at them. Thanks to the CELL Core inside of her body, her powers and magic are continuing to increase much more than ever before, not just her ability to use icy magic, but also her physical strength and speed. Her physicality is very immense, due to the fact that she has been able to grow with the CELL Core long enough.

As with Yumi, she had than used her technique, Ice Pillar Fan, and she sliced around and destroyed as much of the infected as she did, which made Yumi spoke out.

"Okay, not we can leave. Ganyu, let's move and find Prometheus!!!"

Ganyu heard Yumi, and when she did, both her and Yumi escaped from the area very quickly, so the infected don't get to them. They ran as fast as they can, and they did all that the could to get away. But as they continued to run, Hounds appeared, and they all possess the same volcanic-looking veins that the Zombies have, and their fangs are covered in flames. They launched fire at them like dragons, but Ganyu and Yumi jumped into the air and avoided them. The Hounds look up, and saw that Ganyu and Yumi are in the air, and are about to attack them, when Ganyu suddenly launched arrows into their mouths and attacked the CELL Cores in each of them, killing all of them instantly.

As both Ganyu and Yumi landed onto the ground...they suddenly felt a powerful form of heat from nearby. And it is hotter than the magma heat that they are feeling. This made them both suspicious, as Yumi spoke out.

"What the...is it supposed to be hotter than magma?"

Ganyu shook her head...as both Yumi and Ganyu than go to the source of what is making such a powerful heat, and as soon as they got there...what they saw stunned them to the very core, something that they were not expecting. Standing before then and generating the heat...it was Prometheus himself. And the Dead Cell infected is very large, so large that he almost seems to be able to fill up the 2 buildings, and yet, he is able to move in between then without problem, and even his arms and legs are not pinned in a way. He resembles a cross between a goat and a human, with red eyes glowing, and horns that have a few openings on them, almost resembling saber blades, and a the chest has a ribcage that is exposed, and it is showing the Dead Cell Core inside of it. Fitting that it resembles a demon of some kind, as the area that they are in looks somewhat like hell.

This made Ganyu and Yumi shocked, as they both stepped back, and Prometheus stood up from the ground, as he began to walk towards them, his hand extended our, as he than summoned what seems to look like a hybrid weapon of some kind, for it appears to be a cross between a trident and a sword, with the Trident being the one that is pointing up, and the sword stabbing the ground that Prometheus stands on top of. Prometheus glares down at Ganyu and Yumi, as their own eyes looked shocked and a little nervous at seeing this thing, and then, Yumi than spoke out the Dead Cell's name.

"Prometheus..."

Ganyu stepped back, as she has her bow and arrow out, and she aimed it, as she is ready to fire onto the large Dead Cell boss, waiting for it to make an opening for her to attack with. And than, Prometheus rose it's trident into the air, as he than slammed it down onto the ground, as the ground began to glow from immense heat. Ganyu and Yumi, realizing what it is about to do, leapt up into the air, and landed onto s building beside them, as the area that they are in bursts into flames, as Ganyu and Yumi barely got out of harm's way. But the fire Dead Cell is not done yet, as he than swung his hands, and made a row of fire that launches at the both of them, as both Ganyu and Yumi went up into the air, while Ganyu than used her bow and arrow to fire a charged icy arrow at Prometheus, as she ate word to attack one of his eyes. But Prometheus used the sword part of the Trident and sliced the attack before it can hit him, before launching a fireball at Ganyu and Yumi. But Yumi than made an icy wall to try and block the attack, and while she succeeded, it also shattered the ice and destroyed it, which shreds her clothes. At least Ganyu's are undamaged.

Ganyu and Yumi landed onto the ground, as both Ganyu and Yumi duck to avoid another fireball that is coming out towards them. And the fireball missed, as it hit a building behind them which then exploded.

Yumi looks at Prometheus, as she glared with anger at the sight of him, she got badly damaged, as she stood up, and she than spoke out to Ganyu.

"It seems that Prometheus is going to be harder than expected..."

Yumi than stood up, as she closes her eyes, sternly. She raises her arms and puts them together, her fans unfolded, as she than spoke out.

"Than perhaps...it is time that I make Prometheus feel the cold embrace of Death."

Yumi opened her eyes, as she spoke out.

"Ultimate Ninja Art, Ice Queen!!"

As she spoke out, an ice tornado appeared from where Yumi is positioned, as the ice began to damage even Prometheus, who is caught inside of the attack, and needless to say, it was painful, as Prometheus is forced to take a step back, and the twister was gone, and Yumi finished her most powerful transformation.
