Samara was a bit more honest than her brother, but it was hard to believe that they would follow different paths. They had been doing almost everything together since birth, after all. Even when one faced a problem along the way, they solved it instead of trying to follow another path. In any case, they could feel themselves getting stronger, so there was no reason to complain or leave the area for the time being. At the very least, until they settle down and find partners for themselves, they will work together. Perhaps they will even continue like that after that.
"I suppose I can slow down on the construction of the tunnels, while I still didn't find a way to camouflage the vehicle, everything has been pretty much fine while moving at night," Billy thought. "I guess I can use that just as a way to improve my Earth magic while doing something instead of just turning mana into experience."
Billy experimented with fighting by himself inside the dungeon while using the weights, so he had some extra mana. While his attacks got heavier, his speed naturally decreased, and it was particularly troublesome to make sudden evasive maneuvers. That was another thing he had to add to his training routine…
"Papa!" Christina said with her arms open and closing and opening her fists as if she was calling him to approach.
Billy couldn't help but smile since that was really cute. He had begun his training with evasive maneuvers, but it seemed that he couldn't do much while he was looking after the kids. As for Hector, he was just watching him without making a fuss. He was showing any expression on his face as well. It seemed that he didn't find his father cool, but he didn't think much of him either. Not like toddlers think much of anything aside from their mothers.
Billy stopped his training to play with his kids, but his mind still was on his training. The effects of Sage Wisdom were quite fearsome, and Billy wanted to learn the same version for the other parameters, but he had no idea how to do that yet. It was so easy to learn the first skill…
"I guess for the time being until I find the answer, I should train the support skills as much as possible," Billy thought and used Support Strength on Hector, who was having a hard time getting up after falling.
While he was still a bit slow, Hector still got up quite easily. He was naturally a sturdy boy who tended to fall a lot. He never cries when that happens. By watching his son getting up, he wondered if some kind of impulse was necessary to learn more passive skills. Hector used the impulse that his arms gave him when he was getting up, but then again, that probably would only work on active skills.
"Hmm… Maybe to learn the other versions, I can't rely on mana, I relied on it before and it worked because that skill increases my magic power, but for the other parameters…" Billy thought while rubbing his chin.
In the end, Billy had an idea, but he decided to test it while his kids were having their afternoon nap, and it would take a while for them to spend their energy.
Two hours later, Billy put the kids to sleep, returned to the garden, and took a deep breath. If his idea was wrong, then he would regret that experiment. He infused a lot of his mana on the weights on his arms until he barely could move them. Each one of them weighed over five hundred kilograms, so never mind his arms, Billy couldn't even take a step forward. Still, he persevered and tried to move his arms as much as possible without using buffs or even Fierce Aura. That being said, he was more or less forced to use his breathing technique and control his stamina to move. Again, he was using a lot more than usual. That wasn't helping him learn skills, so he stopped. Billy almost could hear his muscles cracking and muscles being ripped apart… on a small scale, but he persisted. Thanks to that, his hard work paid off.
You learned Brute Strength.
Brute Strength: passively increases your strength by five points per level.
Billy sighed. That also was a simple skill to learn, but he just hadn't tested all his options. In any case, he made the skill level up a bit because he needed some extra power to take the weights from his arms. It wouldn't be a good idea to make the skill increase that much while he was still doing his physical training. Hopefully, the training will keep showing the same results while it helps him level up that skill.
"Thanks Hector, you helped papa a lot just now," Billy said while patting his son's head when he returned to their room.
With that, Billy confirmed that skills that affect his parameters can be learned without the use of mana. Still, Billy will have to do many tests to learn the tricks of the other skills. Even if he doesn't become stronger as a dragon, parameter-wise, he still would be able to do a lot more with the full set of those skills.
Instead of training that skill while he was thinking of how he could learn the others, Billy decided to take a break and focus on finding the others. Learning the skills to passively increase his speed and dexterity will be particularly troublesome since those parameters weren't like the others. Just by running faster to his limits won't do. That was how Billy learned Dash. As for Dexterity… Billy didn't even have a single idea about that. That being said, he didn't get anxious. Instead of that, Billy just decided to focus because he eventually would find the answer. All the things that troubled him until now eventually were solved, after all.
