Abyss and the others went down to save the new other version of Sans as fast as they can, as Abyss than extended his arm out, and summoned Abyss Blasters all around the other Sans, as they fired as quickly as they can, with the Zombies falling down to the ground, without any difficulties whatsoever. Spheres dropped down to the ground, as Abyss teleported down to meet with the entity.

"Are you okay?"

The Sans entity looks at Abyss in the eyes, and spoke out.

"Y-Yes, I'm okay."

Abyss nodded, as he than spoke out.

"Good, than let's get out of here."

Ganyu and Ravel landed onto the ground, as Ganyu. took out her orb again.

However, this time, she is ready to use it more effectively than before, as she than threw it up into the air.

The ice began the rain down on top of the entities, as the Zombies began the slow down from the effects of the ice sphere that they are under the effects and constant bombardment of. Ravel Phenex than took the chance to use her hellfire to launch their attack at the Zombies and incinerate them without any sort of hesitation whatsoever. And this time, Atla Fayon decided to take her own initiative and began to attack them physically. She used her fist empowered by her CELL Core and punched them in the face, knocking their heads off, and killing them, though not as fast as the flames or the Abyss Blastere, as it took about a few seconds for the CELL Core-infused punches to kill the zombies and put them down.

As that happened, Abyss than noticed that more and more of the zombies are appearing, and there are too much for all of them to handle. In a panic, Abyss roared out to them.

"Shit, these things are everywhere!"

Abyss than turns around and beckon everyone, even the other Sans, as he shouted out.

"Let's get outta here before we become their food!"

Everyone agreed, as they than as fast as they can, as Ravel and Atla Fayon ran for their lives, along with Ganyu. Abyss and Ravel could have decided to fly away, but they are not leaving them behind, especially that other version of Sans. Speaking of which, the other version of Sans, who has a worried, scared look on his face, than spoke out to Abyss.

"What are they?"

Abyss did not looks at the other Sans, but he does take the chance to speak out to him.

Definitely something that is not any sort of human, devil, fallen angel, angel, or all that sort of stuff like us. They're some sort of Zombie."

Abyss and the others kept on running, when a sound stopped them.

"Rrrrrrgghhh..."

Abyss, the other Sans, as well as Abyss' group, all of them screeched to a stop, as they heard the sound of the group came at them. When it was heard, all of them looked to see a new creature that had came to their way. And these creatures are different.

They are quadrupedal in appearance, almost resembling foxes in a way, with their bony feet exposed, as well as their ribcages, revealing the cores between them. Abyss was not amused at this, as he spoke out.

"Great, apparently the 'Zombies' aren't the only creatures around here."

The creature than ran, the creation is running at inhuman speeds, and Ganyu than decides to do something about it. 

Ganyu than throws her Ice Orb into the air once more to try and slow down the Hounds that are coming towards them. Only problem is, the Hounds are much more faster, and didn't make that much of a difference. They closed in towards the group, with Abyss shouting out.

"Oh no you don't!"

Abyss than fired an Abyss Blaster, but unfortunately for Abyss, the quadrupedal creature leapt up and
dodged it.

"Shit, that thing is fast!"

The entity snarled a little bit at Abyss, as Abyss thought inside of his head.

'Thing...this can't be right.'

The quadrupedal creature got close to Abyss and was ready to bite off his head, when all of a sudden, something sliced the entity in half. Than, the entity began to split apart, before turning into globs of red liquid, and standing in the place where the entity was present in, is a familiar face, one that Abyss had seen back in the world that Ganyu herself had lived in.

"Yo."

Abyss was stunned, as he spoke out.

"Lucidia?"

Ganyu looked at Abyss, and spoke out.

"Do you know her, Abyss?"

Abyss nodded his head at Ganyu, as he spoke out to her.

"Yeah, I do. She and I met back in your homeland once and said she's an interdimensional space hobo."

Than, 3 other hounds tried to attack Lucidia, only for Lucidia to slice them all without issue, faster than the eye can blink. When she is done, the globs of what were once the creature fell down, and she turns to Abyss and began to strike a conversation with him.

"Nice to see you again, little sans. See I told you I'll protect you from danger."

Abyss spoke back to Lucidia, annoyed.

"Nice to see you too, Lucida, and I'm grateful for saving us. But just because I'm small doesn't mean I'm defenseless."

"Still haven't learned your vertically- challenged-ness weapon" yet? That's too bad."

"You haven't changed much since we met."

"Try to put more effort into it next time."

Lucidia than looks at Abyss group and she spoke out to them.

"You three must be Ganyu, Atla Fayon, and Ravel Phenex, yes?"

The 3 girls nodded their heads, as they confirmed it. Perhaps Abyss talked about them, or perhaps Lucidia had been watching over them. She than turns to the other Sans and spoke out.

"Oh, you are new here. My name is Lucida, What's your name?"

The other Sans finally was able to give out his name to her.

"M-me? My name is Paper Crane."

Lucidia looks at the now introduced Paper Crane, deep in thought, as if that name sounded familiar, before she nodded and spoke out.

"Nice to meet you. Unfortunately, this world isn't safe anymore. It's in critical state and no longer stable. This place is now classified as an undead AU."

Paper Cranw was stunned, as he looked around, and he began to realize what Lucidia meant by that.

"No wonder why I can't feel anything alive here. I thought the void was scarier."

Abyss than looked behind Lucidia, and his eyes widened a little bit in disgust and shock, as he than quickly spoke out to the group that is about to be in a conversation with one another still.

"Erm, guys? I hate to kill the mood... But the pack of Hounds isn't out of commission just yet."

Lucidia was caught in the attention of that, as she than turned around, along with Ravel, Atla, and Ganyu, as they look to see the residue of the Hounds beginning to reform.

Unfortunately for the group, however, it is more than just reforming. Because the Hounds had been cut to different halves and pieces, the Hounds began to multiply, growing into new Hounds, similar to when a seastar can make a clone of itself whenever a small bit of the limbs together are present.

Needless to say, the group is now in very big trouble, due to the fact that the Hounds have multiplied and cloned themselves when they had been cut to many pieces. Lucidia gripped her scythe righty, while Abyss's scarf than began to glow Aqua Green, as Abyss began to activate his CELL Core's magic, as his eyes flared dangerously at the Hounds before him. The Hounds than began to charge at the group, in order to maul down on them, but Abyss, refusing to let that happen, raised his hands onto the air, before he slammed them to the ground, and made a bunch of bones rise up, in hopes to block them off.

But the Hounds changed this by leaping onto the bones, in order to try and catch them. But Lucidia leapt up into the air and attacked them. But as she does that, she notices that the Hounds also managed to dodge Lucidia and go to Paper Crane and Abyss, as well as his group. But Abyss is not planning on letting this happen, as he than fired his Abyss Blaster at the Hounds, incinerating them as fast as he can.

And while that is happening, Ravel Phenex began to combat against them in a one on one fight against the Hounds by herself on her end. She raised her hands into the air, and launched CELL Hellfire at the hounds, and burned their bodies alive, all in an effort to try and destroy them, like Abyss' doing. She began to fly up into the air, and began to spread the Hellfire all over the Hounds, and the flames spread to the closest ones next to each other, almost like the hounds are the trees of a wildfire. As that happened, one of the Hounds attempted to bite her head off, but Ravel noticed this, as she than launched her hand around the neck of the Hound, and grabbed it as tightly as she can, as Ravel glared at the Hound, and sets it on fire, as the Hound than dropped down, and is incinerated by the CELL Hellfire, which Ravel was able to deploy without effort, as Fire and CELL Together are very effective in killing the Hounds and the Zombies. She than looked up and saw that there is a Hound...no...no just a hound, but a couple of hounds that are ready to pounce right on top of her and try to eat her head off. But Ravel is able to avoid getting hit by the Hound, and rushed as fast as she can, as she than flies up into the air much more than before, and made a ball filled and condensed with CELL Hellfire, which than exploded onto their faces, incinerating them. She than landed onto the ground, and saw that Ganyu is trying to fight back against the Hounds herself, but the best that she is doing is slowing them down.

Ganyu tried to use a charged ice shot, but this only slowed them down. And this mainly annoyed them at best. She even used her ice orb, but this only slowed them down a bit more, and did not stop them. Ravel Phenex, rolling her eye, than summoned a magic circle above the pack of Hounds that are trying to attack and maul down Ganyu, and she burned them all alive. They fire spreader fast, before they were than burned to ashes, as the cores fell down to the ground and disintegrated without issue. Ravel Phenex landed next to Ganyu, and spoke out to her.

"Are you okay?"

Ganyu nodded her head, as she then spoke out.

"Yes, I am okay. Thank you, Ravel.

With Atla Fayon, she is shown to be moving ad fast as she can, as she punched and kicked the Hounds as hard as she can, in order to kill them, and is able to infuse her kicks and punches with the magic of CELL itself. And while her attacks are not as strong as Ravel Phenex's flames nor the Abyss Blasters, the Hounds still die from the CELL-infused punches if Atla Fayon, who is able to cause a lot of agony to them. She kicked their heads off, punched her hands through and into the cores of the entity, to make killing them faster, and even made them explode. One of them attempted to bite her, but she heard it's footsteps and dodged the attack. Although she cannot sense then, due to being undead, and thus, have no life force, she can hear then, as she grabbed one of them by the tail, and began to slam them repeatedly onto the ground, and cause a lot of ground pavement damage, before she than leapt up into the air, reeled her fist back, and punched the fire with a CELL-infuse punch, exploding the hound.

With Abyss, as he fired a bit more and more of the Hounds, he was able to vaporize them, but he than noticed something that caught his attention, and it is something that is very odd to him, that he began to take notes on during the fight against the Hounds that are attacking them.

'Something doesn't seem right here. The creatures vaporized by the blaster are killed instantly...But the sliced ones regenerate into 2 monsters, cloning and multiplying.'

He than looked down at the cores are on the hounds, and he also began to realize that there is something amiss inside this fight.

"Come to think of it, these cores are almost identical to CELL cores, but that can't be right. Out of control Cells have a very short lifespan...unless..."

Abyss' eyes narrowed a little bit, but than, his eyes widened, realizing what must have happened to them.

"They've mutated!?"

Abyss, upon realizing this, immediately flies up into them air, and raised his right arm, as he than summoned Abyss Blasters and CELL Bones, before he spoke out to Lucidia.

"Lucidia, move away!!"

Lucidia looked up at Abyss.

"Huh?"

But Lucidia saw the blasters, and she teleported out of the way, and as she did, the Abyss Blasters fired, as Ravel, Ganyu, and Atla turned around, and they saw something that they would never usually see in Abyss' face. He looked panicked, almost horrified, but it didn't take long for Atla to finally realize why it is that is making Abyss act the way he is.

'It seems like, he has found out the truth of this place, has he not?'

After the Abyss Blasters were done being fired, Abyss felt his body shake, as he landed into the ground, and he felt immense amount of distress in his body, as Lucidia looks at Abyss, a look of concern is on her face, as she spoke out.

"What's wrong, you're shaking."

But Abyss did not answer:
