Father and Son's training

[1 year later]

Right now Billy was 2 years old, his limbs were long enough to permit more free movement, and he was able to walk and run with ease. Since his muscles wasn't developed enough, it was still hard making a good sprint.

His feet were still too small to stop in some instants, so he need to decelerate from a run  when he needs to stop.

But he was still able to train a bit, so when there was no one watching over him, he walked to his room or outside and lifted the heaviest thing he could, passing from a rock to a glass full of water.

In terms of language, he was developed enough to make proper phrases and understand many words depending on the context in which they are used. Apparently, he was in Yowa Village, it was in the border between the south region and the central region of the nameless continent in which they lived in.

For now he needs a body ready for his father's training when Billy will ask him to train him, it would be strange for a 2 years old kid to train himself, so he concealed it to not obtain reputation about it.

Kids were more evil than one could think, if you weren't like them, then they would bully you till you cry, so for now it was best staying in secret, when he reaches a certain age, he could even start raping corpses, no one would be like a kid and bully him about it.

He learned about this continent in general, there were animals called Danger Beasts, but he saw only slightly weird ones, like slightly mutated dogs or strange carnivorous plants. For the really big or dangerous ones, Bora would deal with them for himself, and he would always come out without any injury.

Sometimes he would go out with Sarah to play together, like now. He, Sarah, and the guy with with she has a crush, were near a lake, playing together. The guy was called Ray, and seemed a really kind guy, the classic anime protagonist type.

Sarah: Hey Billy, try to throw a rock and see how many times it bounces. 'Hehe, I will make both him and Ray proud of me for my 8 bounces!'

Billy nodded and with a smile he picked a small rock, before he turned towards the lake, with his back facing the two teens, and in that moment, his smile turned into an evil smirk. He put himself in his stance and threw the rock on the lake… 9 bounces.

Sarah: ...Eh?

Ray: Woah… Kiddo, you can do really great things!

Billy's evil smirk turned back to his innocent smile and turned around before rubbing his head in embarrassment.

Billy: Hehe, I was just lucky… Hey Ray! Why don't you try it?

Ray: Yes, yes. I'll do it too.

Ray picked up a stone and while Billy looked at the lake itself, disinterested, Sarah gazed at Ray with a charming smile on her face. 

Ray smirked and threw the rock… 3 bounces.

Sarah: Pffft… Hahahahahahaha! 

Ray blushed in embarrassment and turned away from Sarah, who let out an angelic laugh at Ray. Billy smiled at the scene, which went unnoticed from anyone. Suddenly, Ray's stomach grumbled, causing Sarah to laugh even more while Billy chuckled.

However, Sarah's stomach was the next one to grumble, this time Ray and Billy laughed together as she blushed, turning just like a tomato.

Sarah: I… I-I guess we can have lunch now… I brought some food…

Soon, Sarah set out everything and gave Billy and Ray something to eat.

Ray: It's delicious like always, Sarah!

Sarah lightly blushed and said with a slightly arrogant face.

Sarah: Hmph, it's obvious that it is delicious, who do you think you are talking to?

Ray chuckle, already familiar with her behavior, then he said.

Ray: Heh, still, thank you for the food, Sarah.

Sarah blushed at those words and turned her head away.

Sarah: Hmph!

Billy just continued to eat peacefully, enjoying the love comedy between the two of them.

[4 years later]

Right now Billy was 6 years old, Sarah was 18 years, and she turned out to be a really beautiful lady, even if she was smaller than the average group of females, both in height and in… Places… And it turned as one of the buttons of Sarah that should never be pressed.

Today was a special day for Sarah… So Billy and Bora were dressed in a suit and sat with the others in a church, where there were Ray dressed in a suit like everyone else and Sarah was dressed in a wedding dress… 

Yes, it's Sarah's marriage, when both were 16 years, they got together, and Sarah stopped being a Tsundere around Ray, everyone present was happy with their marriage, especially Billy, who wanted someone to protect Sarah since he was too small and weak.

The Chief was the one speaking for both of them.

Chief: Ray, do you take Sarah to be your wife, swearing to our God to grow old together, supporting and loving each other, to the very end?

Ray: Yes, I swear.

Chief: Do you, Sarah, take Ray as your husband, supporting and loving each other, to the very end?

Sarah: Yes, I swear to our God.

Chief: And so, as your leader, and in front of everyone present and watching this marriage, I will declare you two as groom and bride, you may kiss each other.

Sarah threw away her bouquet of white roses and hugged Ray, who almost fell backwards because she pushed herself on him, and their lips sealed on each other.

Everyone clapped at the two lucky people, and started the party. Billy smiled as he saw Sarah with the most happiest expression he ever saw on her. And seeing Ray's face, it seems that he wasn't the only one that want to see that expression again.

Bora patted Billy's back and said with a grin.

Bora: One day it will be your turn, Billy. You won't understand it now… But the day when you get married, that will be the day you will be the happiest… After the day you will be father.

Billy: ...Dad… what are you even saying? 'Seriously… Why the hell are you even telling me that when I have 6 years?'

Bora: I said it before, you will understand it when you will be bigger.

Billy shrugged and both of them looked again at Sarah and Ray.

[Night]

Billy was going on the training ground, where Bora was training alone, the sky was full of stars, but Billy's gaze was attracted towards his father's strength, each swing of his great sword caused a storm of wind that slowly destroyed the ground in which he was in.

Bora's mastery on the heavy sword can be considered on par as someone who is a master with a light sword, the colossal sword, despite its size, was going so fast that it couldn't be seen, in a mere second, his swings exceeded 8 or 9, and then he finished with a slash downwards.

The heavy sword connected with the ground, causing a great tremor and a giant crack to appear on the ground, if Billy didn't know better, he would have thought that it was an earthquake.

Billy yelped when he was sent half meter in the air from the tremor, attracting Bora's attention.

Bora: Ah, Billy! So it's you. Why aren't you in the bed?

Billy: Sarah and Ray were doing too much noise in the nearby room and I couldn't sleep.

Bora faked some coughs as he turned his head away. He knew what Billy was talking about, this was the night where the bride and the groom "Love" each other, even though he didn't knew that Billy knew more than he let go, he would not let him know what they were doing until he reached an appropriated age.

Billy: ...Hey dad, can you train me tomorrow?

Bora: Hm, train? Why?

Billy: Because I want to be strong!

Bora paused a bit before he chuckled, and then he started to laugh. Billy just waited for him to finish to laugh, and when he did, he slammed the blade on the ground, causing another enormous fissure to open.

Bora: How strong?

Billy: More than enough!

Bora grinned and said.

Bora: Alright, I will make a man out of you! We will start tomorrow, just like you said, but be prepared because it will be a brutal training!

Billy: Yes! ...Where do I sleep?

Bora: You can take my bedroom while the two of the… finish…

Billy nodded and entered back in the house, going towards Bora's bedroom to sleep. 

[Tomorrow]

Billy was out with Bora in the training ground that was full of filled up craters and fissures. At the side, there was Ray and Sarah that watched with curiosity.

Bora: Alright, Billy, today will be the start of your path towards the power, I will guide you only in the first half of the path, you will need to work if you want to go to the second half, or just being able to not fall down from the first half. Do as many normal push-ups you can!

Billy: Yes!

He immediately took out his shirt, revealing a thin body, but even without any trace of muscles, there was still a balanced level of strong flesh and hard bones due to the weight lifting and rush he did in secret.

Doing bodyweight exercise was the best thing he could do at the moment, it didn't cost almost anything and was the easiest to do, but after that, he needs some weights bigger than himself.

1… 2… 3… 4… 5..... 10… 15…. 25!

Billy couldn't do any more and fell down, tired. Bora, Sarah and Ray were surprised, even if Billy's body is really light, he shouldn't have much strength compared to his body, but making 25 in the first attempt… No.

Bora: Billy, did you train previously?

Billy: Yes, I wanted to be stronger than dad so I trained before today...

Bora smiled and nodded in satisfaction, finally he has a companion for his trainings, better yet, it was his son! He would have waited till he was 12 or 13, but he asked him when he was 6 years old! This brought a great satisfaction to him.

Sarah: Hey little brother! Good luck on your training! If you can pass it successfully, your big sister will introduce you to some girls!

Ray: Hahahaha, yeah… I tried training with father-in-law, but…

Bora: Hey Billy, ignore the words of that stick over there.

Sarah and Billy laughed when Bora called Ray a "Stick", he was really thin now, but he still carried enough strength to carry a sword and swing it. The stick in question blushed as he looked down in embarrassment.

Bora: Hehe, alright. Billy, you will rest for now, after 10 minutes we will start with bodyweight exercises.

Billy: Yes, dad!
