"This isn't good, Siphyr." Liliane remarked as she observed what was going on with Siphyr.
Diane also quickly jumped out of the bed.... Naked, and she immediately came to Siphyr's back and latched onto it before saying,
"Sister Liliane.... Please get him on the bed. I'll help him control and calm down out of control Yin essence in his body." She calmly said and Liliane used her telekinesis ability to gently put Siphyr on the bed.
At the same time Maya had her previous doubts confirmed. 'So, they're in a relationship like that.... Master and Diane.' She thought.
"Siphyr... Try absorbing our Yin essence now to breakthrough. Don't worry.... I'll help you."
Hearing her words Siphyr went on and absorbed the Yin essence currently in his body running amok. However he didn't want to waste it just for a breakthrough instead, he used it to strengthen his body and soul.
This was after all what he originally planned to do after getting their Yin essence and he immediately circulated it to his soul and body.
The moment he did that he felt his bones crack and his muscles renewed. His body was destroying itself and reforming it again using the essence.
Once that was done he felt his body get stronger, compared to his previous one it was like comparing a baby to an adult's body.
After that, with the help of Diane he controlled the essence to move to his soul, to be exact in his brain.
The soul was an unknown element in this world, nobody knew how to cultivate their soul. However for Siphyr, he was able to do it with the help of the dual cultivation technique.
It was as if this thing was made for him alone. But that doesn't mean that he's able to do it, it will go smoothly as cultivating the soul is several times more difficult than normal cultivation.
One had to be careful and it might even take several hours if not days to cultivate the soul with that much Yin essence.
And so the essence went to his brain and his mind immediately became blank for a moment from the strong energy it contained. But with Diane's help he was able to regain his senses and controlled it to move towards his soul.
His soul was located inside the center of his brain and it was miniscule in size contrary to the large amount of Yin essence.
Even so Siphyr didn't stop and circulated the Yin essence to cultivate his soul, carefully and precisely without any mistakes.
Just like that a few hours passed by and they were still in the process of cultivating the soul.
At that moment Maya still hasn't gotten over knowing that Siphyr had done 'it' with Liliane and Diane.
So while Siphyr and Diane were in the middle of their cultivation, Maya who was currently next to Liliane asked.
"Senior Liliane.... Did the two of you really do 'it' with Siphyr...?" She calmly asked and Liliane replied as if she was confused, "What do you mean.... Ah!" She blushed when she finally realized what Maya meant.
She meant that if the two of them, her and Diane, do 'it' with Siphyr. Although she was flustered at first by the question she still replied albeit in a weak voice.
"Y- Yes.... Please don't report it to Lily or she'll immediately rush her to do it with Siphyr."
"Don't worry senior Liliane, I'll keep this to myself and I promise I won't tell a soul." She declared and hearing it Liliane heaved a sigh of relief.
Afterwards the two didn't say anything and waited for the two to finish. They didn't eat much or drink water. In their realm eating and drinking wasn't necessary for them anymore.
Several more hours passed by and dawn arrived, the sun wasn't out yet and Siphyr was already on the verge of completely absorbing all the Yin essence.
Thud!
The moment they finished, Siphyr fell unconscious and Diane fell on her back at the bed.
"Siphyr!" Liliane shouted when Siphyr fell unconscious but she calmed down soon after noticing that he was still breathing.
"Huuu.... That scared me...." Maya sighed as if she was on the verge of death instead of Siphyr. She was extremely worried about him and she felt better when it finally finished.
"Don't worry.... Siphyr is just exhausted from cultivating his soul..." This time Maya and Liliane became shocked at something else, "C- Cultivating the soul?!! How is that possible?!" The two of them exclaimed and Diane explained what happened to the two of them.
"Siphyr... He used your Yin essence to cultivate and strengthen his body, reforming his muscles, bones, and even internal organs strengthening it even more. It was a harsh process that even I felt pain just by seeing it." Diane explained, her tone felt like she was about to cry.
"Then, after that I was surprised when he didn't use my Yin essence to breakthrough. Instead of moving it to his Nucleus he unexpectedly made it go to his brain. I was surprised at first but I decided to trust him and help him deal with it. However as expected, his mind went blank and I used my powers to help him regain his senses."
To her it was terrifying, if not for her Siphyr would've lost his mind becoming a useless person, or even worse he would've died. She didn't want to ever do this again as she might get a heart attack from worrying too much.
Then, she continued her explanation, "As we successfully moved the essence to his brain..... he did even something more terrifying, he made go inside his brain towards the center. However... unlike before his mind didn't go blank and he was able to do it without losing his mind."
"There.... I saw something for the first time, something I wouldn't have seen if not for Siphyr locating it. It was something so miniscule just like its presence that no one would've found it. However... Siphyr was able to locate it and he used his Yin essence to cultivate it."
"That thing... His soul, I could feel it getting stronger though its size remained the same. After that the whole process went smoothly and his soul got stronger than ever before. That's why he immediately fell unconscious as his mind was greatly exhausted."
"I... I'm also exhausted but for an entirely different reason."
At the last part of her sentence they knew she was stressed as Siphyr almost died. Also, they finally understood that Siphyr was able to cultivate his soul. This was something that no one should know or else it'll cause chaos around the world.
To that the three of them looked at each other's eyes and they nodded as if they mutually agreed to something.
