Austin could be seen in a wide grassy field - in his inner dimension - watching Yukikaze's training on her speed and double-sword techniques as she preferred using double-swords.
They were short and not long to give her more options for more techniques.
She was training with Sakura as she was more experienced than her, although what Sakura used was daggers but her movements were quite similar to the double-sword movements, so Austin told her to train with her to enhance her movements. Besides, both types depended on speed and agility.
Austin had an endless arsenal of weapon techniques thanks to his All Master pack that gave him so many techniques that was used by great figures in the past like Artoria Pendragon or Scathach Skadi, he had all of their techniques about how two use a sword or a lance and many more.
He used that to train his wives who were using sharp weapons like swords like Asagi or lance like Shiranui.
Regarding Violet, she preferred using her hands, so he taught her Taekwondo techniques, making her attacks more destructive, she was a genius in hand-to-hand combat as well which made Austin more pleased.
She even used the Taekwondo techniques that she learnt and created her own style that suited her better.
His other wives like Ephildis and Dinelynd were taught magic as they were proficient in it. One was proficient in dark magic and the other in light and nature magic, so Austin with his endless mana pool and affinity to all elements along with his perfect control over mana, taught them diligently and efficiently making them stronger.
He also taught Stella the way of sword as her style was western unlike Asagi who was eastern style.
Victoria as well, was taught magic and how control and communicate with her elements that she was so proficient with which were Fire and Ice magic.
Austin wanted to teach Mi-Kyung Cho some magic as well and surprisingly, she had a good mana pool that was bigger than most magicians with great affinity to nature element that could use the surrounding nature to either defense or offense, so it was quite versatile.
Tina also had a rather large mana pool as well with great affinity to space element, making Austin both surprised and happy that she could have an affinity to such a great element.
For Anita, she wasn't a magic type but a physical type person who used weapons and aura.
The aura she used was different than what Asagi used as it was also mana but rather manifesting it outside it flow throughout her whole body, making her stronger, but with her new race, this disappeared and could use magic now with a huge mana pool and great affinity to darkness element, but she still preferred using weapons.
She preferred using Ax than a club as she was more proficient with it and Austin made sure of it when he fought her and beat her badly.
Selena also trained on magic and sword as she used a long Katana, although her style was eastern but it was different from Asagi, so Austin gave her a suitable training program. She also wanted to train her magic as well as she wanted to be a magic swordsman who used both sword and magic, surprisingly, she had affinity to lightening element which would increase her speed even more beside many other uses.
The others who were Lilith, Ava, Eve, Ruby and Judy were more proficient in light and holy magic with Lilith having a great affinity to the Enchantment and Charm magic like a succubus and that was evident from how her body emitted a very sexy and alluring aura that could charm men, all of that beside her affinity to holy and light element, but not on bar with the others.
And lastly, Lya, Roxanne and Luise, the three were also training on their respective fields of expert.
Austin gave all of them a good training program to increase their mana pool and at the same time make them stronger and more proficient in their respective element and magic.
He trained all of his wives while he had a rather special training for himself as their training wouldn't benefit him at all as he was already a master in all weapons and had a prefect control over magic that he could destroy the world if he wanted. He also helped Ingrid with her training and assisted her in controlling the spirit of the dragon that was sealed inside her, so she can use its power without suffering any backlash.
Austin's body was so strong due to the summoning pack that gave him endless stamina and health, so he could accommodate all this power, but all of this didn't make him immortal at all, because of his weakest point, his soul.
His soul could be damaged heavily if it was attacked with a powerful attack and that could lead him to death on the spot if not healed properly.
Thanks to Leona who inhabited his soul, she was nurturing it, but that wasn't enough, he needed more power and more nutrition to be able to use more of his power if he needed because although his body was very strong and all to accommodate all of his power without blowing up, but his soul wasn't immune from it, so he needed to get it stronger to better use more of his power as his soul would suffer from a backlash if he used some powerful spells. After all, his mana originated from his soul.
He had many ways to do it and one of them was training his spiritual power that was the source of power to his soul.
This was the thing that he was least proficient with, so he needed to train it to get stronger before searching for another way to get his soul stronger and by using a way that Asagi—who is considered the one with the highest spiritual energy—taught him.
So he left his wives and went to the forest toward the Tree of Life to train his soul there.
They didn't know about Leona as she herself said that it wasn't the right time to show herself to them yet, she would do it when she feel it.
'Hey Freya, is there a reward the can make my soul stronger?'
[Yeah, there is, but why tiring yourself with it when there is another better way to do it and it would be more efficient and effective than any other way.]
'Hoo so there is a way like that, as expected of my dear Freya, you are so knowledgeable.'
[Fufufu yes praise me more]
'Then what is the way?'
[Oh, just make a world tree inhibit your soul, but that after you get your soul stronger to a certain limit so it could live inside you or else you will explode from the sheer amount of power it can give you. Or you can just look for a fruit called Spirit Fruit, this is the fastest way btw, the other one need more time but the effects are huge than the later.]
'Ok thanks.'
[You are welcome.]
'...'
[I've been scammed, right?]
'...Just your imagination~'
[BASTARD!]
'Fufufufufufu...'
Then Austin continued his way inside the forest while smiling.
'It seems I will follow my old plan. Train my spiritual energy and nurture my soul and make it stronger before looking for a cute world tree that want to inhabit my soul and nurture it and better if it was a woman because I can't ever let a man live inside my soul as I don't swing that way at all.
Austin felt a shudder when he thought of that possibility while walking.
