Rein started Anneshia's treatment immediately. She was very careful with the way he handled all that. He did his best to control the power of his soul damaging attacks as much as possible to just lightly injure Anneshia's soul.
But if he kept on being so cautious then this process would still end up taking a lot of time. For that reason Anneshia herself asked Rein to speed up the process. Rein was really unwilling to do so as he had very little experience dealing with souls.
But as Anneshia was fine with it he did start to increase the amount of power he was using and the damage he was dealing also increased. But the danger to Anneshia's life did not as her broken cocoon break ability was still just as strong as it was before.
But the recovery speed of Anneshia's problem did increase. Seeing that Rein became almost like a machine that was continuously dealing just the right amount of damage and at the same time he was observing Anneshia very closely to make sure nothing was going wrong.
After continuously doing that for three days straight he was almost done with removing the influence of the dungeon core over Anneshia. But at those final moments something big happened.
The whole dungeon suddenly started to shake and Rein was able to feel that the dungeon itself was getting annoyed and angry by their presence. Rein was also sure about the reason behind it. This dungeon core was basically a parasite to Anneshia's soul. All the powers it held mostly came from Anneshia.
As Anneshia was a very powerful person herself, the dungeon attached to it was also very powerful. But as Anneshia started to separate herself from the dungeon, it started to become weaker and weaker which was something that the dungeon obviously did not appreciate.
Still so far there was no hostility directed toward Rein and his group. That was because Anneshia was controlling the dungeon to not see Rein's group as an intruder. But as her treatment removed the dungeon element for her soul, her controls over the dungeon started to weaken.
That was the reason why this place suddenly started to show hostility toward Rein and his group.
This was definitely a problem. They were at the deepest depth of this dungeon. So it was their enemies home ground. Here the dungeon would be able to use its strongest monsters without holding anything back.
Just as Stella and Tasha had expected, the dungeon was really trying to do something to Anneshia while attacking them with monsters. But this attempt by the dungeon was way more underwhelming than Rein had expected.
It was extremely hard for the dungeon to make its influence to expand even a little bit inside Anneshia's powerful soul. So even if Rein was not here, the dungeon would not be able to accomplish much.
But now that he was not distracted by the attackers this dungeon sent, he was able to notice a very special thing.
When the influence of the dungeon was in an inactive state, it was scattered throughout Anneshia's soul. For that reason Rein was not able to specifically target any part which would only be harmful to the influence.
But after the dungeon tried to mess with Anneshia actively, suddenly the influence gathered at a certain point to start the expanding process. This was the perfect chance for Rein to get rid of this influence once and for all.
With that in mind, he immediately removed the part of the soul where the influence of the dungeon was concentrated and Anneshia used the cocoon break to regenerate the damaged part with the contamination.
That was a big blow to the divine core and immediately it lost almost all connections to Anneshia.
With a last slash Rein dealt a serious amount of damage to Anneshia's soul and after this wound was also healed by Anneshia's cocoon break, he was able to completely eliminate all the influence of the dungeon core from her soul.
As soon as all the shackles holding Anneshia back were broken she was finally able to attack the dungeon which was something she was not able to do previously as she herself was also a part of the dungeon. As soon as she was able to attack again, Anneshia used her sword to slash at the dungeon once.
She was extremely angry with this dungeon as this was her prison for many Millions of years. So the slash she made was serious and had the irritation Anneshia had always felt toward this place mixed in it. So, the power of this slash was insane.
Immediately with that one slash the whole dungeon including the monsters inside it and also the dungeon core was destroyed and the conquerors found themselves outside the dungeon.
