The soul essence core is something one attains when they reach the Saint realm (12-circle).
While it says soul essence core, in fact, it is nothing more than something like a core that stores attributes' energy.
In general, attribute energy is always drawn out when applying skills. The skills are nothing more than the transformation of attribute energy.
Of course, there are certain skills that use nature's power, like Mark's thunderblast skill or Gravity Dome.
However, in general, when people use their special skills, they always bring out their attribute energy from their cells.
But, every now and then, there will be a genius who manages to bring out their attribute energy from their cells, without expending their ether energy. For example: Song Yue's great grandfather-Song Tai, and her best friend, Lin Xue.
What if one isn't such once in a once-in-a-century genius then?
Then, they have to wait until they become a Saint Realm Spirit warrior (12-circle) and form the soul essence. Then, all they need is to store it in their soul essence core, which is formed inside their soul, and use it whenever they want. The more one has attributes, the more they have essence cores.
Chang'e is a moon goddess, blessed with divinity. Hence, apart from the ice essence core, she also had a divine essence core. That's where her divine energy attacks come from.
What the demon was asked is her essence core itself.
Giving it away will not make her cripple or something. However, it will take time to rebuild the essence core; possibly ten years or even hundreds of years.
Obviously, she was reluctant to make such a deal. "Why do you need it?" She had to respond with a question, for his deal followed up with a threat.
But, will one of the demon kings of Ars Goetia reveal his true intentions and give her the answer she wants to know?
Nope.
If not for the fact that this guy is protected by Leviathan, he would have been killed by now. But, no one wants to incite the hatred of the Guardian."
"Interesting." Mark got more curious about the demon that loves peace. "How did he win the favor of Leviathan?" He asked.
Duke Alloces explained, "We are not sure what happened but some time ago, Leviathan returned to this realm being heavily injured. Several demon kings are ready to slay it, but Marbas sacrifices his demonic essence to heal some injuries of the guardian. It averted those power-hungry lords' plans. Marbas didn't finish there.
He continued to stay beside the guardian and slowly healed him for a long time, bringing it to its peak once again.
While Leviathan's existence is always a threat to the nine demon kings, it is also the thing that protects our realm from any kind of invasion from the Heavenly Palace. We are talking about the being that could fight head-on against even the Jade Emperor even with its lower cultivation. And you want to form a contract with it. I seriously don't understand what's going on in your head."
Mark attentively listened to the entire story and he had suspicions about that event. If Leviathan is so strong, how come it was injured by Houyi, who is nothing more than a mortal? Chang'e said that Houyi was also its contractor.
Perhaps, its strength was restricted when it battled Houyi?
When he summoned Bael, the latter's cultivation was also restricted to 2 realms above him. So, that is the case, then?
At the same time, Houyi was said to be the divine archer, blessed by the Jade Emperor. But, he had a contract with such a powerful demon? Could it be possible?
Mark's situation is different. He merely had the mark of a deity planted upon him. He doesn't have any blessing of a Deity.
Maybe, someone manipulated the story to hide something?
Something is missing in this puzzle. But, what is it? Mark wondered.
On the way to the secluded on the hill, Mark also learned many things about Marbas to understand his strength as well as his personality. He formulated a plan by the time he reached the destination. He was also confident that he might be able to cut a deal with Marbas, who seems to have an obsession with herbs, fruits, and plants.
Imagine his surprise when he saw a powerful barrier erected around the hut and Alloces cried out, "Oh no, Bael's infernal domain. Is he going to kill Marbas?"
"Eh? What?"
