Let see, he is very profound with magic and he can manipulate energy to that fullest. If energy can be predicted, I can tell that energy has its weaknesses as well. So I ended up nodding in understanding that the way to beat my brother is making him madder that he'll lose his temper and his movements.
Brother has a lesser temper than me. He is likely the same person who will hit others because they don't often have the same opinion. Brother is the same, his temper will likely bring him down with it. 
"Second brother, why do you hate me so much?" I disappointedly said and held back my urge to attack. I then stood atop the rooftop and looked at him as he levitated from the sky. 
Nice skill thought. "Ah!?" He then started laughing like a total psycho. "All you did is to dishonor the family, and you keep on pissing me off. Isn't that a reason you should die for the sake of me ascending as the second crown prince!"
That's a ridiculous reason for him to be this desperate in destroying me. Also ascending to the name of the second crown prince? Ah, that's funny really! What the hell is wrong with these people!?... No we are monsters, besides humans are different to a monster.
Logic and understanding doesn't go along with ogres like us. Ah, my head, I wanna yell. 
"Ridiculous," I mumbled and smiled. "Isn't that because brother is just too weak that you wanna eliminate me first before the others? Cause I'm not like them, I am stronger than them aren't I?"
Yeah looking at his reaction. That must be the real reason. Third and fourth brothers are strong but I am stronger to them by at least three levels. So the second brother who was known as the weakest brother wants to secure the position by making the third and forth brother believe that they are allies just to get rid of me. 
Lucifer isn't lying when he says he is the strongest. In fact, he was the strongest amongst the three but the first brother is still the strongest amongst us.
Alas, this is one of the big family problems. 
Although we have different mothers, they are all brothers to Lucifer. I am a son of a maid, same with the second prince and the third but the first and forth brother have the same mother—the royal queen. 
She died so the production of son ended with me. My mother also died, as well as the second and third. That is the reason we were raised like this because the father didn't raise us as well as his son. 
He only expects greatness from us. I don't know why he decided to make another crown prince when the first is said to be the successor already. However, I now understand that getting us in trouble is not the only thing he had in mind. 
"That's why I hate you, because you are such a nonsense to this family!"
With his rage going to explode. He released a strong energy that he was trying to shoot me off, and so when I noticed the lights that were about to hit me. I immediately used a fire slasher to match up with his attack and retreated as it exploded in front of me. 
Even if he has harnessed his dark energies. Getting slash by fire, it will immediately cause it to explode and that is why fire slasher can be used against the defensive. Although I just acquired the shield formation, it's not hundred percent it can withstand the energies that dissolves almost everything.
There is a view of his hidden vulnerability. I lifted my hand and I used my mana to release a long and short energy that is gathering around my hand. After feeling all of the energy entering my palm, I immediately aimed at my brother's body and shot it like a rifle gun. 
Strong and formed fireballs immediately were released and it all struck my brother like an open book. When it hits the target the whole surrounding exploded in smoke making it hard for me to see if he took damage from it. 
Darn it! I shifted my gaze and immediately used my hands to block the attack that I suddenly noticed when I turned around. He was able to escape it? That's so... I then flew back and retreated while looking at my hands that were distorting. 
It's not painful but I can see my blood sprouting like a river in the mountains. I couldn't help but look at my brother with intense entertainment. Even though I made myself weak, I knew he would do that so celebrating his fall on that thick mist was not the greatest thing one can do. 
It was a predicament. Not that I care. 
"Inventory," I thank Tartys for being advanced. He's good at this bruh, well in the case of having him upgraded that is. I can evolve him into a more powerful companion and his advance thinking, his notice and detection will upgrade as well. 
Anyways, I need to patch up this injury. I don't have skill regeneration like the main characters in some kind of a second-rate novel. Maybe I'll make one later, and hopefully it can raise my level a little higher I guess.
I took out a bottle of potion out of my inventory. The bottle of potion contained low healing potions that were awarded to me when the 《creation》was created.
It may be a weak potion, but it can heal injuries much like the one I sustained. That is enough to bring back half of my HP and MP. 
Should learning medicine be proficient at this point, jeez. 
I took the bottle and drank it. I waited a few seconds before I felt the urge of tickles that was happening on my arms. The moment I look, that gruesome scene appears in my mind. The way the healing potion heals my wound is very concerning at that moment but I let go and looked at the finished product.
It was good as new and didn't feel as if my arms were broken earlier. I tried moving my fingers and it did work. That should do for now, the damage I sustained is dangerous without the healing potions. 
I could have died there—yup, despite not having to feel pain. 
Well then I'm happy I survived. Dying again is really not something I want. I've spent my two lives dying at the age of 15's and above. Come on, who died at 16-17? Or when I'm just about 1 year into becoming 20? 
Anyways I don't wanna do that again. That feeling is unpleasant at that moment, I don't want to repeat the same scenario of going through hellish pain thinking that darkness is a friend. 
I had it coming...
***
Brother didn't like it when he saw me and my hands that suddenly healed on their own so he tried to dissolve me again like he just did a minute ago. 
In order to stop him. I puff and multiply the battle flames, and shoot him down like a thousand arrows. This time he didn't predict this move and instead of dodging, he used up most of his mana using his escape skill that he can't use in another hour. 
Yeah, he has that skill. 
"Give up brother," I said and watched him struggle in escaping all of the flames raining down in his head. The more flames, the more it won't be easy to escape the attack. 
Although I did not only harm my brother. I also harm the town, and the mansion which is not in burning flames. I don't have any regrets so I was not sure. Hence seeing the town burn from the same flames I shoot, it made me think that I should not use our citizens to plunge destruction.
However, I don't have the ability to extinguish the fire. So instead of using water, wind or something that can light the fire off, I use my fingers and try to minimize the fire as much as I can to control them in my palm. 
That is the skill 《battle flame》I can control whichever it can spread, and that is also because I'm using status to control the flames that are now gone.
"Hmm, very thoughtful I see, but look at me when we are fighting, dammit!"
Removing the flames removes the battle flames as well. So instead of using an arrow, I used vertical arrows created from the flames and looked at him. "See you on the other side brother," I utter before releasing all of the pressure and flames into one attack. 
I need to end this as soon as I can. There is no sense in this fight and I think father thinks the same. The city is being infected by the fight and I can hear and see everyone's panic. 
So as a prince, I shouldn't do this anymore. I have to think about the innocence getting screwed up from the mess we brother's both started. I am not like that, I am a heroic war veteran and I choose to save people instead of condemning them. 
Hence I will be different to people like my brother. I will not use innocent people, and I will not try to interfere with problems I wasn't part of. 
I mind my own business seriously.
