For the past year, Lucifer had also been training his body physically. In this world, people were generally divided into two groups.
The first were mortals who didn't have any talent or attribute for law, and the second were practitioners who had an attribute for law.
Laws were divided into three categories: supreme laws, heavenly laws, and elemental laws.
Laws like Fire, Earth, Water, Air, Metal, and their derivatives like Ice and Lightning fell into the category of elemental laws. These laws were easier to practice, but their strength was also comparatively lower than heavenly and supreme laws.
Laws like Light, Darkness, Illusions, Concealment, Life, Death, and Corrosion fell under heavenly laws.
Laws like Space, Time, Destruction, Creation, Gravity , Karma, Fate, Order, and the law that contained everything—Chaos itself—fell into the category of supreme law. One might say that if Chaos contained every law, it should be above supreme laws, but no, it was true that Chaos was a type of law that contained everything, but the law user could not use the other laws separately because then that wouldn't be Chaos. So, it could be understood like this: Chaos was just extremely powerful energy that could not be defended against, but it could be dodged.
Every practitioner had an attribute in one of the laws present in this universe. There were some rare cases who had attributes in two or three laws, and these cases were only seen in elemental and heavenly laws, but having more attributes didn't give you any advantage unless you were very talented because practicing even one law took a lot of time, and if you were not talented enough, then forget about even advancing in one law.
Talent was defined by how much you were attuned to your law and how good your concentration was while practicing the law. There were three categories for talent: Supreme talent, Heavenly talent, and Normal talent.
There was no perfect scale to measure talent, but it was shown as you progressed in your training in laws and how much time you took to reach certain levels, you can also check by using a rock which shows your speed of absorption of law.
The strength of law practitioners was divided into three categories: Celestial, Immortal, and Mortal, with 10 levels in Mortal and 10 levels for Immortal, and for Celestial, no one knew about it because once someone reached the Celestial level, they ascended to a different world, and they never made any connection to this world after that.
Lucifer had already asked his mother about her and his aunts' levels.
His mother was a Level 1 Immortal practitioner of the supreme law Chaos, and she reached that level in less than 100 years, she was a supreme talent. His aunt was also a Level 1 Immortal practitioner, but she had dual attributes of Life and Fire, and she was at the Immortal level in both of these laws. She also took less than 100 years, she was also a supreme talent.
And since they were born from their mother's blood essence and genes, they had acquired everything she had—her talent and her law—so that meant he and his sister were going to be attributed to the Chaos law.
Lucifer started doing his physical exercises to grow up as quickly as possible, but his motivation for exercising was different.... After he was done with his physical exercise, one last exercise was left, which was his cock elongation exercise. He always stretched his dick to the point it started hurting and held that position for some time, and he did this exercise daily for 15 minutes, and since the adaptability of his body was heavenly, he had already started seeing some progress.
With this speed, he would definitely reach 10 inches, maybe surpass it...hehe. He had to stop this exercise now because he thought that it had reached the maximum he could achieve by stretching at this point of age.
Now he had to wait for it to naturally grow for sometime, and with how this body was maturing, he thought puberty came at an earlier age in this world.
Once his dick exercise was done, Lucifer slept soundly.
*****(8 years later)
Lucifer was lying on their bed, watching the ceiling. Today, he had turned 10 years old. He had just woken up and saw his sister who is already 15 years and fully developed adult according to this world, she was sleeping peacefully, and she definitely took after the looks of their mom. Their mom also said that in her younger days, she looked like his sister.
When humans turned 10 years old, their bodies reached the stage where they could sense the laws they were attuned with, so that meant today was the day when their mother would take them to the place where she trained in the Chaos part of this domain, yes his sister had said she will start training with him so she holded her training for 5 years.
Also, in this world, the puberty of boys and girls started at the age of 10. Pregnancy in girls also started at the age of 10, yes, girls could become pregnant at age 10 if they wanted, and this was applicable only to law practitioners, not mortals. But this was not advisable, because baby born would be very weak and smaller than normal babies.
It was like this: due to law practices, their internal organs developed faster, and similarly, the sexual functions also developed earlier, their height also increased because the empowerment of laws strengthened the bones, and increased their size. If he have to guess, than he looked 16 years old as for the earth standards right now.
Lucifer read this information in a book that went by the name *Human Anatomy* in their library, most law practitioners got their perfect height by nine to ten years of age.
And yes his dick has grown to become a monster, he hadn't measured it yet but it was definitely as big as some big bbc's he had seen in porn.
Lucifer stared at his sister's body, which has grown completely, exactly as busty as thier mother
"Hmm...yawwwnn...good morning, Lucy"
She greeted him while yawning and hugged him.
"Good morning, sis. Looks like Mom still hasn't arrived yet."
Lucifer also hugged her back.
Whenever he woke her up, she always hugged him and tried to sleep more. In the past, he let her get spoiled by allowing it, but not today. He put some strength in his arms and picked her up while sitting in a lotus position.
"Wake up, you sleepyhead. Today is a special day, and you're already 15 years old, so you're old enough to not let someone else wake you up."
And as they sat up, she didn't let him go; instead, she hugged him more tightly with her legs. He was in a lotus position, and she was sitting just above his dick, which was already in a morning wood state, and now that it was touching her pussy through their sleepwear, it became fully tight, somehow poking her.
"Brother... there, something is poking me down there."
Lucifer wanted to answer her , but he didn't know what to say here, she definitely knew what it was..
"What do you think it is?"
After saying that, he pushed his hip a little upwards, like thrusting, and poked her more deliberately.
"Hng...I...I can't see, so how would I know what it is? But I feel a little weird down there."
Of course you will, sis...geez, it's so stimulating...this is the first time he's touching a pussy with his dick, even through clothes, it's was heavenly experience.
"There is only one thing between my legs, sis, and you already studied human anatomy, so you should already know it."
While saying that, Lucifer jerked up again.
So good.
"But tha...that's your penis, and it is used only for peeing and baby-making...why is it hard right now?"
Her voice was trembling a little, and he knew that she is doing it on purpose, they have read the book, it also gave simple description of what sexual reproductive organs are and what they are used for.
Since she wanted to play, he will play.
"Hey, sis, we still have around 20 minutes till Mom arrives, so do you want to learn more about this weirdness?"
Lucifer jerked again, this time harder.
"Hmmmm...i-if you want, then sure, brother."
"Good."
Lucifer pushed her down on the bed and saw that her expression became a curious one, wondering how far he will go.
"Let's remove our clothes since we're going to remove them anyway when we'll be washing, and you should stay there; I'll remove yours too."
"Alright, brother."
After Lucifer removed their clothes, they were both naked on the bed.
