The process had already been initiated. There was no need for any further involvement from the Ghost Queen. All she had to do was wait, and maybe even observe the process with her own eyes.
Amidst the waiting period, she heard the knocking on the door which surprised him. Normally, no one came down to her lab, but today it was the second time that something like this had happened.
"Who is it this time? I don't need any more materials." She scratched the back of his head, ignoring the knocking on the door.
She believed that if she just ignored it a few times, the person outside might think that she wasn't here and just leave.
Contrary to her expectations, the person outside did not leave. Instead, the knocking only became stronger as if the world was going to end if she did not open the door.
Frustrated, the Ghost Queen floated over to the door. She opened the metallic doors, finally catching the sight of the person on the other side.
"Axxel? What do you want?" The Ghost Queen narrowed her eyes. She wondered if he already found out that she was using his subordinates to perform her experiment.
Fortunately for her, it was impossible to see that part of the lab from the door. Even if someone was suspicious, they could not confirm without entering the lab themselves.
"Am I not invited here?" Eren asked casually. While he talked to her, Yelen entered the hall to take his disciples from the Cage.
Even if there was to be a fight, he didn't want his disciples to be caught in the aftermath of the battle.
"I am busy today. I don't have time for you. So leave," she coldly told Eren, who was disguised as Axxel.
She stepped back to return to her lab and close the door.
"Is there really a need for such distance between us?" Eren asked, stepping forward. If possible, he didn't want to let the door close again as that would only leave the option to break it open which might alert a few people.
....
Inside the hall, Yelen broke open the lock on the cage, observing the two girls who were deep asleep.
"Take them away," she told Felona while opening a spatial portal the moment the Ghost Queen was distracted.
Just to be sure that no one saw the portal or the bodies being moved, she even covered the surroundings with Mist, making it impossible for any security mechanism to make out what was happening.
Even if there was any recording mechanism, it was impossible for them to see through this fog, finding the culprit.
The only clue left behind was the spatial essence that connected to the Spirit Realm but it was easy to suppress by spreading more chaotic energy in this place.
Eren was already a master in that, just like he previously covered the essence of the Portal with Sea Dragon Magic remains.
Felona carried the two girls on her shoulders before entering the portal which closed behind her.
....
"You really shouldn't have been so stubborn. You asked why there is a need for such a distance between us? You're right. There is no need for distance between us. Let me turn you into a Ghost, making you a part of me."
The Ghost Queen looked at Eren, her eyes filled with coldness.
"After that, there won't be any distance between us. Right?" With a blurry vision, Eren couldn't see the Ghost Queen's face clearly but it was clear that she had a smirk on her red lips that she occasionally licked.
"Still, you are very lucky." She gently caressed her own lips which had tasted a man for the first time. "Even if you are going to die, you will die after getting a kiss from me. Be happy even in your afterlife as you receive my first kiss."
