Going back to Austin. He was still working on the formula without stopping for even one second to take a breath or go and have a meal. At least to ease his mind and give it a rest, but due to his recent body changes, he didn't need that.
He could go for the whole month or even years without even stopping because as a dragon, his brain was far better and sturdier than the normal human mind. Besides, his dragon heart is replenishing his energy with each passing second, making him have like endless energy supply as long as he didn't consume too much in one go.
And beside his endless mana pool, he could summon more characters from different dimensions and universes to make his soul stronger. He could abuse this ability of his to make his soul stronger at a faster rate, that if he could summon endlessly like before, but with the new restriction, he could only summon only three per year with a cooldown of 5 years.
From a human perspective, this restriction could be seen as quite harsh as humans cannot live for long, they only have average of 70 years in their whole life with some may live longer, but it won't go beyond 100 in most cases.
But from a supernatural being perspective, this is not much as their view of age is so much different than humans. They could live for so many years like 200 or 500 and some could even live for more than 1000 year.
Gods could live for millions, and devils could go beyond 100000 years, angles are immortals as long as they don't die from the Misama of the underworld or by anything that could affect the souls.
Dragons are the same as well, they could live for millions and don't die like gods, no, dragons are so close to gods, their souls could reincarnate again even if they died.
Anyway, Austin didn't care about the restrictions if being honest. But he would use the three summons to summon some powerful characters to help him as he feels that something big is going to happen in the future and requires him to gather some powerful allies to help him.
And what better than fate universe summons? Although he could only summon women and girls, but he already had his sight at two. Two of the most powerful characters in that universe.
But now, the formula is more important than the summon, once he finished, he would go and do it.
. . . . .
Some time passed until finally Austin decided to take a break as he stretched his his body while leaning back on the chair. He already spent a whole week without going out of the lab.
"That's...good~ now I could say that the formula is quite complete, just need some final reviews and adjustments before the final product is ready for conduct."
He said while looking at the stakes of papers in front of him. All of these papers were filled with so much detailed information that contained many different details about the correct doses of the materials used in making the serum and how to make it more effective and mass produced with the most sufficient cost to make it affordable for all people around the world.
He improved the whole formula not adjusted it, this was something that no one could do. A formula to make something that is far difficult to make and requires a very careful and deep thinking and observation and understanding seemed like something impossible to make.
But Austin did it, without any help of his dragonic powers. And only in a week. Something that could take years to make could only take a week or a month for Austin, that's why the CEO told him to do it.
He knew Austin's capabilities very well and used it all without letting anything unused, to the fullest if I may say so, of course for the company before the people. After all, only money talks to these money fanatic people.
Business world is quite scary, don't you think?
"Anyway, I need to go and visit my wives or else they might come and cause a great destruction to the city." A small smile adorned his face as he said that because he knew very well how strong his wives became after the power up they had when they had that intercourse at the day when he came out of the shell.
With that, Austin stood up and prepared to go out. He looked at the papers he wrote and stored them in his inventory before creating fake ones with fake information on them and put them in place. They had some truth to them tho.
'Don't want him or anyone to come and take a look because I know myself very well.' He thought before going out of the private lab. He didn't leave anything untouched in the lab. Even the glassy board was filled with so many complicated calculations that needed some deep thinking and time to understand.
Austin knew that those scientists in the main lab respected him but at the same time hated him. He was far smarter and intelligent than them, overshadowing anything they do. This made them despise Austin to the core and they won't leave any chance to mess up things for him. This is wasn't the first time that he saw something like this.
He knew that very well, those who hate the successful people are everywhere.
Walking outside of the lab, he saw everyone focused on what they were doing without casting even a glance at Austin and he could only sigh and let them be. He didn't even care, only his wives were in his head at the moment.
But from the corner of his eyes, he saw Homoura Toji glancing at him before looking back the paper in his hands. Austin knew what was inside but didn't dwell in it too much, it's not his business to tell people what is right and what is wrong, they are not babies anymore.
'Let's go let's go, I bet they are angry with me because I didn't visit them for a whole week like I promised. And I knew that today would be a long day.'
Finally walking out of the company that gave off a cold atmosphere, Austin could feel the warmness of the sun and the free air around, beside the natural energy dancing around him like little girls wanted to be pampered by him. He was like their father and they loved him so much.
After all, dragons are beings of nature and nature revolve around them, his body took the impure natural energy and purified it before releasing it back to the world making it breath more comfortably.
Like a father caring for his child, giving it the best of the best he could.
"Now, let's go."
With that, he walked to an alley so no one could see him before he teleported back to his mansion in Tokyo.
Unknown to him, a very big surprise is waiting for him back at home~
.

Back at the mansion.
Austin appeared in the front of the gate of his mansion and pushed it open before walking inside with hurried steps as he was eager to meet his wives after a week from not seeing them. He felt like out of energy and needed his wives to recharge.
But as he stepped inside the garden of the mansion, he sensed a strange and very familiar presence inside. This presence was very different from his wives.
Austin gulped a mouthful of saliva before he walked towards the doors of his mansion with steady steps as he wanted to make himself calm before the meeting, after all he hadn't seen her for a very long time.
It was so sudden and without any prior notice, not even giving him the time to prepare.
He opened the door and walked inside. He noticed a strange shoes that didn't belong to one of his wives at the door step, clearly belonging to that familiar presence he felt when he arrived.
Austin was quite nervous and happy at the same time to see that person.
He could already hear the voices of his wives and another woman coming from the living room.
He walked slowly in the hallway nearing the living room with every step he took. Until finally he found himself standing in front of the door of the living room.
But before he could open it himself, the door was opened by one of his wives, Marjaana.
"Welcome back, darling~" her sweet and calm voice greeted him making him suddenly calm and relaxed.
"I'm home my dear~" A very handsome smile adorned his face making her blush before he walked as he kissed her delicious lips.
All the women inside stood up as a greeting for their husband and Austin smiled at them, but then—
"You finally came, brother!" A very energetic and melodious voice echoed in the room grabbing his attention before looking at the girl who now became a fine woman with great assets. She really grew up.
This was the person that he hadn't seen for a long time. His dear little sister.
