Those two weeks passed quite slowly, but Billy saw Lily's making a lot of progress in the meantime. Not actually seeing it, but he noticed that they were staying inside the dungeon for longer periods of time, and his materials were finally starting to stock in the warehouse. Every week, several wagons carrying leather and pelt travel the state to sell those, so the stock never lasted for long. Billy even gave some words of praise when those kids made him earn a gold coin the entire day. Thanks to that, they relaxed and asked him to show them how he could make lightning from his hands. It wasn't from his hands. He just had an easier time manipulating the air when it was close to him.
"They have gotten better. They will reach the same level as your previous students if they stay here another month," Billy said.
"How can you tell?" Lily asked.
"It is just a feeling," Billy replied.
"Well then, see ya later," Lily said.
"If you see the others, tell them to follow the schedule, we will need to go back in sixty days, and the trip will be a lot harder for you if we delay it any longer," Billy said.
"I am not that weak, you know, just being pregnant didn't make me useless," Lily said.
"You should also need to consider the kid inside you. Are they as strong as you are now?" Billy asked and then changed his tone. You can't take any chances. Anyway, if anyone is too slow on their work, I will leave them behind."
Lily couldn't joke around any more than that because Billy was serious. She also realized that Alexander lost his mother during birth, and while no one knows the reason why that happened, one could guess that it was due to the war between tribes and because Nikola had to leave her behind to fight. That was a common thing, so something must have happened during her gestation that she kept as a secret. Billy wasn't the father of her child, but he was someone who looked after those two for over a decade, and now his protection and thoughts would extend to their child as well.
"Okay, thank you," Lily said before leaving.
The next that would come was Sarah's and then Alexander, Kate, and Natalie. The areas they had to work in were far away, so it couldn't be helped. Alexander must be sick, worried about leaving his wife for two months while she was pregnant, but it was work, so it couldn't be helped again. After witnessing and fighting in wars, they realized that was the only thing to prevent the allied states from falling into the hands of the enemies. In a sense, they were also fighting to make sure that their kid would have a peaceful future.
The next day, Alexander showed up as expected and also as expected. The first he did was ask how Lily was. Even after hearing that she was the same as ever, he still looked annoyingly troubled. Recently, Billy had the idea of creating an underground tunnel that could connect the main towns and cities. Still, it would take a while for him to even connect the dungeon town to the nearest one. He wanted to make a vehicle. A magic version of a subway wasn't a bad idea. Still, first, he needed a good vehicle, and he failed whenever he tried until now. Still, when he called some boats that he saw while he was traveling with his grandmother, he had the idea that perhaps if he couldn't take a train, he at least could make the water flow in the direction that he wanted and then use a boat underground. That plan was also troublesome since he would need a lot of water, far beyond what he could take from the air with his mana, like water from a river or lake.
"These plans are quite difficult since I want a secret method of transport," Billy thought while rubbing his chin.
"Hey, Billy, check this out," Alexander said. "I had this idea while I was training a few weeks ago, and I finally managed to pull it off."
Alexander made a block of Earth emerge from the ground with his magic, and then he began to focus. He was about to show some skill, one that required a lot of strength. Billy knew that because he focused that much when he was learning Light Spear. Weirdly enough, Alexander used that skill… still, Billy noticed something weird with his shoulder and his wrist.
In the next moment, even though he was twenty meters away, the skill actually pierced the block of Earth. From that distance, it couldn't crack with just the power of Light Spear, but then Billy noticed a hole in it…
"I see… by adding some rotation to the attack, you concentrate the power of the shockwave in a single spot," Billy said and then nodded. "Still, it must put quite a bit of strain on your shoulders and wrist since they receive all the strength of Light Spear."
"... How did you learn so much after seeing it just once?" Alexander asked, visibly speechless. "I had to think for days to find a way to concentrate all the power in a single spot!"
"Well, it is because you are bad at hiding things," Billy replied. "Nevertheless, it quite the nice addition to the effect of Light Spear. While it can't be used often, you can even take down heavily armored opponents from a distance. Good job thinking of that."
"Hahaha, I actually learned it by accident when I was trying to make the skill more powerful," Alexander said.
Most things were learned by accident. Billy learned a story back on Earth that some students were trying to make rocket fuel for whatever reason. They almost destroyed a building thanks to that.. Still, instead of being expelled, they received another place to keep trying that. Thanks to that, the man went to the moon…
