As he had expected, after turning able to control the bloodline completely, he also turned able to change between his human form and his half-beast form at will without needing to use Shape Shift.
At that moment, the half beast form stopped from being a disguise and turned into an alternative aspect. That fact finally relaxed Yale as he didn't like to cheat Aiwai, but he feared to disappoint her if he said that he was a human as their main bond was their bloodline as half-beasts.
However, at that moment even if Aiwai were to discover his human form, he wouldn't be lying saying that he can just change between forms at will.
That would be strange as it was considered impossible for any half-beast without divine beast bloodline, but it would still better than confessing that he was a human who obtained the bloodline without any after effects.
After all, Aiwai knew that Yale was a reincarnated expert, so Yale felt that she would be able to understand the existence of some rare capabilities in Yale's body.
While Yale was happy after having mastered the control of his bloodline and his flying capabilities, Aiwai was still helping Wyba with the wind skills.
"Wyba, your brother has already finished. He wins."
Wyba had been trying hard to learn how to use wind skills to power her flight; she was trying to use the same Wind Wings as Yale, something she should be capable of doing as the skill was inside the bloodline that provoked their mutation to the Frost Winged Wolf bloodline. However, although she had improved a lot thanks to her efforts, she always failed at the last moment as was unable to take the last step.
"Wyba knows that big bro is awesome, Wyba needs to train more to not disappoint big bro."
Wyba was frustrated for losing, but that just motivated her to improve more and increased her admiration towards Yale. Aiwai and Yale were both happy to see that Wyba was more motivated instead of dispirited.
While Aiwai continued helping Wyba to train, Yale focused on his archery; since he started to practice archery from the sky, his understanding of archery deepened a lot, and he improved at a fast pace.
Wyba needed five more days before being able to use Wind Wings without problems. Given her age, the time she needed could be considered good, but as she was comparing herself with Yale, she thought that she had been too slow.
Fortunately, that fact was just motivating her to improve more and not disappoint her family.
Yale didn't slack off in those five days, and his archery had already reached the ninth level at the night of the third day, but he was stuck there since then. After all, advancing to the expert stage wasn't easy even knowing the conditions to advance.
"Yale, what do you think of changing the archery practice for something else? I know that you want to advance to the expert stage as soon as possible, but rushing things isn't good for you. You now need to focus on something else. I sent Wyba to train to increase her realm, so I can help you to train whatever you need."
Yale was shocked by Aiwai's words. He was planning to train archery until reaching the expert stage, but he decided to stop after hearing that. If Aiwai thought that stopping a bit was better for himself, he would believe it as she was his master in archery.
On the other hand, hearing that Wyba had gone to train improved his mood, he was happy that his cute yet lazy sister started to train seriously.
"Are you thinking in something? You told me to stop practicing archery, and I can't improve more in swordsmanship for now. Those two weapons are the ones I have more talent with, with others I am not that good."
Yale knew that Aiwai wouldn't ask him to change the training without having some recommendation for him
Yale had practiced with other weapons at the Nacesai Academy, but although the talent in those weapons could increase with his practice, he didn't feel too attached to them.
"I am thinking of something different. Other weapons can be useful to you, but their usefulness to you will be limited right now. At this moment, the best for you will be learning weaponless combat, in other words, Martial Arts."
Yale didn't know how to react, because he was even worse fighting with only his body than with other weapons.
"Sis, I already tried to battle with only my fists, but I am not well suited to that."
Aiwai chuckled, she found funny seeing Yale dispirited due to lacking talent into something.
"Well, that doesn't matter. Only a fool will go to a real battle relying only on the fists. After all, Martial Arts are about battling with the whole body and not only your fists. Moreover, we have a definite advantage when battling with pure Martial Arts, our wings!"
The reality was just as Aiwai said, true battles like the ones Yale had weaponless in the Nacesai Academy wouldn't happen. The only reason the academy was restricting the battle to only the fists was that everyone was too young and they didn't want them injuring themselves too much in the class due to lacking in control the power.
Moreover, in a real weaponless combat, having wings was a great advantage. While flying, the legs were free, and thus it was easy to use them to attack the opponents without needing to worry about the balance. Furthermore, the wings could also be used to hit the opponents.
Usually, the wings were soft and harmless, but if they were moved with enough strength, they could harm.
"I see, let's do it. However, with our difference in size, I can't spar against you even if you go easy in the sparring."
Yale thought that it would be better if he changed a more mature aspect for training Martial Arts, even if he didn't transform into his real height, at least the ordinary height corresponding to his real age would be alright. He felt that the length of the limbs was an important factor and that his current body would be in too much disadvantage.
"That isn't true. Even a smaller body can win against someone bigger with enough ability, being smaller isn't bad at all. Well, it is true that against me you won't be able to train well as that is more advanced. I will create an Ice Golem, and you will train against it. I will be controlling it, so the golem will be able to teach you correctly."
While saying those words, she created an ice golem of the same size of Yale. From Yale's words, Aiwai had understood that Yale lacked experience in Martial Arts and decided to start by seeing how Yale battled.
"Yale, battle with this Ice Golem, without using any weapon or skills."
Yale sighed, the only times he had real battles without weapons he was using skills, but he understood that relying on skills wouldn't let him learn correctly. After all, using skills without weapons and true weaponless combat was still different.
The battle against the golem started, and Yale wasn't doing it too bad thanks to his real battle experience. Even though he lacked true experience battling without weapons and skills, his battle sense was improved thanks to his real battle experience.
"You aren't bad at all. Your battle sense is very good, and that is the most important when learning Martial Arts. After all, you will be able to apply Martial Arts even using weapons. Your main problem is that you haven't any style when battling, but that is because you lacked a teacher and you ended battling thanks to just your instinct and experience."
Aiwai's words were the truth; Yale had only learned swordsmanship thanks to Swordmad; Yale had lacked a good teacher for anything else related to fighting before meeting Aiwai.
In Trade City, Yale was unable to find an archery teacher, but he wasn't interested in other weapons or in weaponless combat, so he just trained his Smith Mastery without even trying to find masters for training with weapons or without them.
However, there was no way paying someone to teach him in Trade City would be better than being taught by his sister who wanted to help him on her own.
