As he flew in the sky at mach speeds that would only look like a blur to any being below that managed to catch a glimpse of him, Osiris could vividly sense the abundance of mana within the surrounding atmosphere diminish with every flap of his wings.
This was an ability that Osiris did not unlock but had already inherently had since birth, which was his mana sense, and had been greatly strengthened many fold since reaching the peak of the third order.
Mana sense was an ability that every being needed to master in order to reach the fourth order, and was something that beings would usually have to hone over long periods of time in order to slowly grasp the fundamentals and allow their minds to perceive the presence of mana.
The reason it was needed was because in order to form a dragon heart, or any other dantain-like structure for the fourth order, one needed to use their minds to sense the certain mana, whether it be atmospheric or whatnot, needed for their specific affinity.
For if one does not filter out and discard the mana not in line with their affinity, and integrates it with their dragon heart, it would lead to adverse effects such as great deformities forming into their dragon heart or just a complete collapse of their cultivation due to backlash of the presence of mana that one was not attuned to once they completely formed their dragon heart.
It would be the same as a human ice affinity user absorbing some fire mana after eating a beast of a mixed attribute, and using the fire and ice mana to form their dantain.
Since their body was not attuned to the heat, they would combust into flames once they fully formed their dantain.
All was not bad though, since one could just start over once they accidentally absorbed the wrong mana, but it would still be quite heartbreaking to have to start all over after all the effort and time one took.
But Osiris obviously didn't have to worry about this since for one he has already honed his mana sense to a vast degree, being able to sense all the different mana within a couple mile radius, but also the fact that he had an affinity for all elements.
And as he flew and sensed the mana density, he grew more certain in the fact that dusk forest seemed to form its own natural mana gathering array.
Osiris felt he was quite lucky to be able to have this as his starting planet in the dragon trials.
Reaching back home by evening,Eris and Aria were excited at his sudden return home, jumping into his arms and showering him with hugs and kisses.
As they were doing their usual greetings after not seeing each other for a few days, Adam came over and asked.
"Well your home early this time, you usually only come back once every three or four days, what happened?".
Osiris just smiled at his question and replied.
"I've finally reached the peak of the third order".
And when the trio heard that, they all became excited.
"You mean that tomorrow we can finally begin our official training!?".
Eris questioned in a happy tone, to which Osiris just nodded his head in agreement.
"Finally!".
She exclaimed, diving into Osiris's embrace even more sweetly, while saying.
"I've been preparing so long for this time!".
While Aria did not speak, she showed her enthusiasm through action as she kissed him passionately.
Adam too was very excited, since he finally was going to have an official teacher to show him the true way of the sword.
His dream had always been to become the strongest swordsman after watching his dad wield the blade.
Back then when his father had taught him about the sword, Adam felt his father looked like a sword god as he demolished wolves that had threatened the village one night, slaughtering countless beasts while he protected his family from danger.
Adam always envisioned one day becoming a true sword deity, slaying his enemies that threatened what he held dear to him.
Breaking from his kiss with Eris, that he had to also confort after Aria's sudden but pleasant attack, Osiris began to calmly say.
"Alright calm down for now, i'm quite tired after my breakthrough and would like to eat and get a good rest for tonight".
To which his wives and Adam nodded their heads to, understanding what Osiris wanted and made sure he got what he needed.
Eris went to the kitchen to start preparing supper while Adam went out back to butcher some meat for dinner.
Aria on the other hand took Osiris by the hand over to the couch, where she made him sit down and gave him a massage.
After all the trauma and pain Osiris had gone through today during his evolution, the feeling of his wife's soft hands slowly massaging his shoulders felt like he had just returned from hell and stepped into the promised lands.
Though every one and a while, Aria couldn't help herself and snuck in some kisses which they both loved very much.
Aria would have gone in for a full blown make out session, had Eris not looked back every once and a while to check in on Osiris.
As much as she loved her sister and was completely willing to share her Osiris, that didn't mean that she didn't want some moments just between her and her husband sometimes.
And who was Osiris to say no to his lovely wife's soul stirring kisses, he knew he would just have to make it up to Eris later when it was just the two of them.
After the heavenly massage that took all the day's stress and negativity that he had built up over the day, Osiris and Aria joined Adam at the table as Eris served the ready meal that she had prepared for today.
Tonight's meal was a peak first order turkey that the three siblings had managed to defeat themselves with teamwork.
Its honeyed skin crispy and golden as Osiris dug into the sumptuous meal, displaying his pleasure with a smile as he dug into his wife's perfect cooking.
"Thank you so much for the amazing food tonight, my love".
Osiris said as he came up behind Eris and embraced her while she was doing dishes.
Feeling his warm breath on her neck and the feeling of his hard muscular body pressed against her made Eris slightly blush as she replied.
"Thank you my love, i do it all for you".
Which made Osiris burst with happiness, leaning down and capturing her sweet lips into his.
His sweet gesture conveying the emotions that he could not put into words.
Feeling his lips and the intensity of his love for herself behind them, Eris felt a burst of happiness as well, wrapping her arms around his neck and pulling him deeper into herself to reciprocate his love.
Going on for a couple minutes, they eventually had to reluctantly break apart, where Osiris then helped her finish washing the dishes before cleaning up and heading to bed, where they and Aria would continue their passion for a couple hours.
Finally ending when both Eris and Aria both passed out from exhaustion and pleasure, clinging onto Osiris as they always did once they went to sleep.
Osiris too eventually succumbed to the night hold, dozing off in expectation for tomorrow's events.
