After taking a few hours nap, Mark's body is now fully charged and he is ready to go into the forest and hunt for magic beasts to sell to the town near them. What Mark has been selling is mostly rank 1 magic beasts and rarely rank 2 magic beasts meat and other useful body parts like the deer's antler or the boar's tusk, the magic rhino hide is also highly sought after because it is a good material to be used as leather armor.
Mark is actually very capable of hunting and selling higher-ranked magic beasts and he will surely become famous and rich from selling higher-ranked magic beast's parts, but he refrained from doing that because money, riches, and fame are not what he is searching for. And getting famous will actually be contradictory to the reason why initially he and Lily decided to live in the corner of a kingdom that is directly adjacent to The Forest of Beast.
Mark stretched his slightly stiff body and after making sure that nothing is wrong and his body is functioning normally, he then heads downstairs. In the kitchen, Lily is currently cooking lunch for Mark so that he can bring it when he goes out hunting.
"Thank you for the lunch, Lily."
"Yes, your welcome Mark."
Mark then saw that Lily prepared 3 containers for the lunch.
"Is there any special occasion or something for the lunch? Why are you using 3 containers for it?"
"Don't you think it is a good time to teach the twins how to prepare the hunted magic beasts and how to sell them to the town nearby? It will be useful for them to have a way for them to earn their own money later on."
"Yes you're right, I should have thought them sooner, but who would've thought we've only got six years."
Hearing Mark's statement, Lily only smiled and responded "But at least we can thank the world for they are different than other 6 years old. If they are just like any ordinary 6 years old, I don't think that I will be able to do this."
"Although 6 years old is not long, we can consider it as luck that we can have that 6 years in peace."
Mark then hugged his wife and patted her back to calm her emotion down. To change the mood Mark then asked
"By the way, where are the twins? I can't see them in the backyard?"
"They said earlier that they wanted to try something and they're afraid that if they do it in the backyard that they will burn the house down, so they went into the forest to search for a large clearing to do the experiment."
"Wait what? Burn the house down? WHAT IF THEY BURN THE FOREST DOWN???"
Lily shrugged and finished her preparation for lunch and handed the 3 containers to Mark.
"Just go check on them then go straight to hunt together."
"Ah, alright, I'll be going then, see you later goodbye!"
Mark kissed his wife goodbye then went straight into The Forest of Beast.
"Okay now, where are those rascals."
'They are using magic so I should be able to sense them right? It will be hard if they only use small spells, but knowing them especially Isaac, I don't think an experiment that will burn the house down will use simple magic such as a fireball. Besides, I just taught them solid magic so they should be practicing that right? Solid magic should be a control type magic where the probability of it running out of control is small, what are they doing that they were afraid of burning the house? Don't say that Isaac is trying to make a 10 meters long flame sword. THAT WILL SURELY BURN THE FOREST!"
'It's no use to think hard about it, whatever absurd thing they are trying to do, I need to find them first."
Mark then used wind and attributeless magic to make him fly high above the trees and searched for his sons' whereabouts. And it didn't take him long, after floating around for a few minutes, he sensed an influx of mana from somewhere and went into the direction of the gathering of mana. And when he is near the source what he found is a large clearing in the forest. The clearing in the forest which should have been covered in green tall grass is nowhere to be found. What Mark sees instead is scorched earth with some rare patches of grass left here and there and in the middle of it all are 2 six years old boys facing each other.
One of them has 2 blades of fire that seemed to be attached to both of his hands. And the other kid has 4 swords that are also made of fire floating around him and all the swords are pointing their sharp edges at the first kid. The kid with 4 swords floating around him extended his hand and pointed his palm at the kid with the hand-blades. The moment he closed his palm, the 4 swords that were floating still before, flew swiftly directly heading into the first kid's direction.
The kid with the hand-blades already expecting the attack of the second kid and he reacted by coating himself with fire to deal with the heat emitted from the flying swords then dodged the 2 swords coming from a low angle by jumping upwards causing the 2 swords to stab through the ground making dust flew everywhere then parrying the remaining 2 swords coming from above by using his own hand-blades, then the 2 swords dropped and fell to the ground below producing even more dust.
When the dust settled, the 4 flame swords are still burning on the scorched ground, and the two swords that were stabbed through the ground is still standing firmly.
Mark was amazed by what he saw that he forgot that the two kids that were throwing sharp flaming swords at the other earlier were in fact are his sons.
Mark then dropped down from the sky and went between his sons and said
"Oi oi oi, stop right there!"
Isaac then said "Hello dad! What are you doing here?"
"Hi dad." (Aiden)
"THAT IS MY QUESTION WHAT ARE YOU DOING HERE?"
"Umm, we are practicing solid magic…?"
"WHAT KIND OF PRACTICE THAT BURNED THIS WHOLE CLEARING IN THE FOREST?"
"Ah, about that, at first I succeeded in making a solid fire sword, but when I tried to hit Aiden with it, he easily sliced the flame sword in two with his hand blade and caused the flame sword to explode, after trying it again a few more times, this time with multiple swords, without me realizing it, the surrounding land had become like this."
"But don't worry dad, after realizing that the surrounding land is scorched, I poured water magic at the edge of the clearing to make sure that it is harder for the fire to spread to the forest, and if the surrounding trees ever caught fire, I will immediately put it out, so don't worry dad, no forest fire guaranteed," Isaac said while putting his thumbs up along with the last sentence.
"Still, burning this clearing is not a good thing…"
"Don't worry dad, I also made sure that no magic beasts were harmed during our experiment, not that it matters if some of them are killed, we will take bonus experience anytime."
Mark then conceded to his son's reasoning and just let it go with the thought that as long as there was no forest fire then it's okay. Mark then focused on the sword that was still firmly standing stabbed to the ground and the two swords that were parried and are now lying on the ground.
"Isaac you said that the sword exploded when Aiden cut it, but how are those swords are not destroyed? What change did you do to the spell?"
"I just improved the concept that you have explained to us a little. I noticed that if we only use the attributeless element to shape the outer shell of the spell, it will be fragile like an egg, but if we add structure and foundation using the attributeless mana, then the construct will be far sturdier than the one that doesn't have an internal structure."
"Wait Isaac, you've just used some difficult words right there, who taught you that?"
"Umm, umm… I read it in your books somewhere I also forgot, but it just suddenly came to my mind, yes I know those words because of your books."
"Okay…" (Mark)
'Do I have those kinds of books though? I haven't read all the books so maybe there are some books that are talking about that kind of topic.' Mark thought to himself.
"By the way kids, I want to teach you guys something today, do you want to follow me hunting today?"
"Of course we want to dad. Let's go!"
"Okay dad."
"Alright let's search for a rank 1 magic boar then. Isaac, you can help me with that right?"
"Yes of course dad!"
Isaac then talked to the many spirits that were following him and asked for their help to find a magic boar. With Isaac's very useful spirit surveillance system, it took them only a few minutes to find a magic boar.
"This way dad!"
Then the three of them started walking in the directions where Isaac was pointing with Isaac leading the way.
'What was that Faust, structure and foundation? Internal structure? What are you going to explain next, physics then? Or nuclear reactor? Remember that we're six years old right now. I'm sure that mom and dad already suspicious of us not being like a common six years old child."
'Yes yes, I'm sorry Gra, remember that if it's about magic I sometimes forget about other stuff.'
'Don't make it more obvious Faust, if these things keep happening they might question us for sure'
'Stop nagging me about it Gra, I already said sorry.' Faust said telepathically along with a sad facial expression that he showed to Angra to show that he really is sincere when he said that he didn't mean it.
'Ah whatever, just be more careful next time.'
'Yes, I will Gra!'
