After a bit of time, Seth gave up trying to think about that matter and proceeded to read about the third stage.

Third-stage Mortal Soul... Where a human started to connect with heaven. A cultivator would only reach that stage, after every single particle of his Soul Essence was thoroughly transformed into Soul Mist.

'So, it means I'm walking this in road, huh...'

The Third-stage Mortal Soul was the last stage of a mortal soul, after that, a cultivator would have to form his own heaven, condensing that energy into something unique.

That phrase was the last thing recorded in that skillbook. After reading it, Seth felt bewilderment and wished to know more about it, but there was nothing more written there, so he could only sigh and give up.

Instead of doing anything else, Seth just kept absorbing and digesting that information for a while, until he eventually felt it was enough. That skillbook opened up many possibilities for him and his women and Seth was very content with what he had learnt.

After that, he decided on taking a shot on those new soul abilities he learnt. Even though there wasn't a practice dummy for him to test those abilities there, he could still get familiar with them.

Seth used his knowledge, experience and soul energy to quickly generate a blob of purple matter in his palms. After closely inspecting it, he was already able to see and feel a vague outline of a soul trap, just like the one he was infected with once before.

It turned out, that he didn't feel it was particularly hard to create that skill, since the Hades Manual had many similar techniques to injure a soul and that required him to generate an offensive soul strike. However, when he tried doing the same for a soul controlling technique that a banshee could also create, he felt it was way harder to accomplish it.

Seth lost track of time while analyzing those skill and the day swiftly turned into night. He wouldn't even notice it was already dark outside, if not for the fact that he heard the door of his room opening once again.

His consciousness swiftly left from his inner soul space and focused on the beautiful figure of the woman that was in front of him.

Arwen was dressed normally and, on the outside, it didn't seem she had any ulterior motives behind this visit, but Seth was able to pick through their Soul Link, that at least she wanted to do something special.

"Welcome back. How was the meeting? Did you get to do something good today?

"

Arwen smiled after hearing his questions and said:

"I didn't know you were such a loving and tender person, but I guess I was wrong.

"

"Ahaha, of course I am. Didn't you see how much I care about you, last night?

"

Arwen smiled and shook her head.

Seth stood up and approached her, but just as the Elf Queen thought he would start his advances on her, something that she also wanted to happen, Seth simply extended his hand and invited her to come closer.

"Arwen, there is something I need to do together with you.

"

"What is it?

"

"Hehehe... Come, please sit comfortably on the bed and I will show you.

"

Arwen looked at him and said:

"Why are you being so mysterious now?

"

"Don't worry, I'm certain that you will like it.

"

Arwen chose to believe him and did as he told her to do. After she sat down, she closed her eyes and quickly entered in a state of relaxation. When Seth felt she was ready, he extended his hands and touched her body. He put one hand over her head and the other over her heart, activating his supreme Evergreen Essence through both of his hands at the same time.

Immediately, the room turned green and his Evergreen Essence stimulated Arwen's Evergreen Essence, creating a resonance between them.

Seth was about to do to her, what he did to Rina. He was going to thoroughly unlock her Evergreen Essence, since he was the source of that power now.

Of course, there would be incompatibilities and Arwen's body would most probably reject the healing part of that essence. But that's when Seth's Corruption would come into play. The Evergreen Essence and her body cells would have no choice but to obey his tyrannical Corruption and merge to a certain point.

A few minutes into that resonance state, the so awaited moment arrived. Seth swiftly injected the Essence of Corruption inside her body and directed it cleanly, making it obey his wishes.

Some minutes later, he retracted his energy and the green light faded away. However, when Arwen opened her eyes, she was thoroughly shocked. She was so speechless, that she even forgot to ask him what had actually happened and could only stay there, feeling the new connections she had with her own powers.

Arwen's left hand opened and a heavy poisonous aura started to circle around it, but when she opened her right hand, she was actually able to feel a mild green energy, an energy that could soothe all ailments.

Before she could even ask how the heck that was possible, she immediately started to request for Seth to do it on Rina as well.

"Seth, please do it with my daughter too. She is...

"

"Ahaha, don't worry, Rina's Evergreen Essence was already unlocked, just like yours. However, I noticed that just like her, your Evergreen Essence has a dominant side and I have no way of fixing that. Even though I have already unlocked Rina's total potential in that field, her healing prowess, is at least thrice stronger than her poisonous aura. And in your case, it seems to be the opposite.

"

Even though Arwen was hearing his explanation, what he told her didn't matter that much, since she wasn't even able to use the Evergreen Essence to heal anything previously.. But now, she could heal and kill.
