Around an hour later. Around 8am in the morning, both Eris and Aria stirred awake, making eye contact and blushed at each other after remembering their debaucherous actions.
Especially Eris, since her sister had witnessed her depraved side, while Aria was a little better off since Eris had passed out before she could whitness Aria being turned into an orgasmic mess.
Osiris opened his eyes and saw the cute blushing faces of his adorable wives, making him smile and say.
"I hope you both enjoyed the experience".
Before leaning down and giving both of them a loving peck on the lips, making beautiful smiles break out on their faces and nodding.
But the next words he spoke made goosebumps crawl along their skin as he said in his deep loving voice.
"But i can't wait to start training the both of you to reach the second order, you both better prepare your minds or you might just go crazy after the first round".
He said with a demonic grin, before giving both of them a tight squeeze on their sensitive ass, making them moan and blush even more furiously.
Both Eris and Aria jumped out of the bed as quickly as they could before the demon couldn't hold himself back again and attacked them.
Funnily enough though, when they got on their feet and attempted to run away, they both stumbled a little bit, still weak in the knees from their morning battle.
Osiris chuckled a bit before they looked back at him with aggrieved looks, however he stared back with an innocent face.
Eris made a 'hmph' sound as she left the room and went to the kitchen to make breakfast.
A little while later, Osiris joined Adam at the dining table, Eris cooking while Aria helped.
Adam smirked and said with an amused tone.
"Took you three long enough, if i didn't know any better i would have thought they were getting eaten by a wild bear in there".
Making Aria and Eris blush furiously while looking down, not daring to meet anyone's eyesight.
Adam laughed wildly at their reaction while Osiris apologized.
"Sorry about that".
Adam simply waved his hand, indicating it was fine before continuing with a casual conversation.
One breakfast was finished, Osiris bid farewell to Adam before going over to both his wives and gave them a deep kiss each, making them slightly embarrassed doing it in front of Adam, and then Osiris left for the forest.
Taking off into the skies again once he got to the clearing and hunting third order beasts.
Today was a special day as he finally made it to the peak of the second order.
He flew deep into the forest and found a cave with a third order mountain lion living within, he swiftly killed and ate it before heading out and killing multiple other third order beasts throughout the day.
By the time evening hit, Osiris made his way back to the cave he had found in the morning.
Checking around the area, he made sure to clear any nearby beasts before sealing off the cave entrance by collapsing it, bathing his surroundings in darkness.
It was fine though, as with his enigmatic eyesight, he could see everything just fine even without light.
He made his way to the back of the massive cave before curling up on himself and preparing to go through the second order part of the secret technique.
The reason he was preparing so much this time was because the second part of the technique, known as the rebirth technique, was the most dangerous part, even requiring a second person to complete it.
The reason it was the most dangerous part of this already deadly body refinement method was because the second order required the refinement of the bones and viscera.
Meaning the technique would require him to reform all of his bone and viscera, aka organs, including his heart and brain.
That was also the reason it required a second person to help, usually an elder of your species or someone strong in the fourth order and above, as they would be needed to continue controlling the chaotic mana within said person to refine and reform their organs since when said person's brain was turned to ooze during refinement, they would go unconscious, resulting in their death when the mana went chaotic and their brain and heart where unable to be reformed in time.
Something instinctual within Osiris however, told him that he would be able to complete this part on his own somehow.
This instinct was so strong that Osiris didn't even feel a shred of doubt that he would be able to fail on this step on his cultivation journey.
The technique was very much worth the risk as in his inheritance, it is said that the few who do manage to complete the technique to the higher levels are some of the strongest beings to walk the world, almost as though they were invincible.
Osiris breathed in a couple deep breaths, calming his mind and preparing himself for the guttural pain that he knew awaited him.
Finished with his preparations after a couple minutes, Osiris began the revolution of the technique, this time starting from the bottom of his feet up towards his head.
He felt the dence mana whirlwind storming within himself, multiple times stronger and denser than when he used the technique at the First Order.
The mana absorbed into his already saturated bones, leading them to be unable to contain the dense mana within, leading to the bones to implode in on themselves and turn into fine particles and disappear from sight.
Osiris' body writhed and convulsed in unbearable pain, tens of times worse than the first level of the technique.
Osiris was unable to just grit his teeth this time as the pain forced his teeth to clench so hard that slight cracks began to fracture along them, uncontrollable tears of pain streamed down the sides of his draconic head as he endured.
However even with all this, he refused to scream out, his pride not letting him.
The pain only got worse and worse as the bones in his legs and arms were quickly disintegrated before his eyes, leaving his arms and legs to lay limply on the cold stone floor as though they had turned to gelatin.
Moving up, the mana began to dissolve his stomach organs along with his spine at the same time, the only thought on Osiris mind was to complete this hell as quickly as possible, willing the mana to continue the process.
Upon nearing his heart, Osiris knew he had to do the final part as quickly as possible, otherwise his chances of dying were almost guaranteed.
So he decided to push the mana into all the bones into his upper body, including his skull, jaw, teeth and others.
Before finally pushing the mana into his heart and brain at the same time, his consciousness immediately going black.
