Around the time Billy returned home, Icarus and Lucyna began to install their surveillance lenses as well. Thanks to that, Billy decided to create a secret room in one of his hideouts in order to leave the mirrors there. Those mirrors would be fed with the liquid of the Edish fruits all the time, and they would stay in front of a bigger lens that Billy created. They were going to show him what was happening in those spots all the time since Billy would keep the final mirror with him. Thus, he won't have to be underground to see if something is happening.
"Well then, now I just need to make the magic drone that can he controlled remotely and then I will be free from all of these constant worries," Billy thought.
Billy soon began to work on that project as well, and while he was doing that, he recalled that aside from looking for the necromancer when he found the demi-humans continent, he also was looking for traces of Angus and Galatea. He had traveled quite a bit on that continent, and he had yet to find any ruins.
"Hmm… there are still so many questions that need to be answered, the more answers I find, it doesn't seem that the questions decrease…" Billy thought.
This time, the chances of Billy finding registers that lasted for five hundred years were absolute zero. Still, he had a feeling that eventually, he would find all the answers in that continent. In any case, Billy worked on that at night and focused on his family during the day. There was no point in getting ahead of himself and ignoring them because of his work and goals.
"It seems you two have improved a lot lately," Billy said while he was carrying the sleeping Helen in his arms. "Like I said, the key to getting better at anything is practice. Regardless, perhaps it is time to increase the difficulty a little."
While only a few weeks had passed since Billy started teaching Hector and Christina, they had made considerable progress. Christina could show the forms of the spear dozens of times without messing with it. Naturally, she was focused on precision instead of speed, and she wasn't putting any strength behind it either, but she was just four, and if Billy wanted to think that she was impressive, no one would stop him. The same thing could be said about Hector. Now he could create a small tower made of earth blocks that were five meters tall… that was a lot of innate magic power that he had.
"Let's see… Christina will try to do the forms while being a bit faster and Hector will try to make a statue of your wolf," Billy said.
Those two nodded attentively. They were being a lot more patient than Billy had predicted. Even when he formed his merry group of misfits that were older, they weren't that cool-headed. In any case, Billy decided to think that they had been raised well, and he helped a little with that.
While Billy supervisioned their training, he also made some prototypes of the drone that he wanted. In the end, even after ten days, he didn't manage to make it while having the ability to be controlled by something like a control. Still, that was a problem that could be easily solved. Billy just had to use Telekinesis. As long as he can see something, he can control it with that skill, and since he was going to put some lenses on it, he would be able to do that.
"It isn't perfect, but I guess it will do the job," Billy thought.
Instead of putting it out of orbit as soon as possible, Billy was going to test the altitudes at which the beam of energy could be used. That was a powerful defense mechanic, but it was far too reckless since it could destroy pretty much any monster in that world. With that in mind, the leader of that place would never be able to check what approached its territory.
"I suppose this also can work to wear out their resources…" Billy thought.
Billy makes the drone to look like a mini airplane so that it could use the aerodynamics to fly even faster and to save some of its mana by flying diagonally. While he was hoping that he would have to go that far, Billy realized that it would be pretty amazing if he could control something with his Telekinesis out of the planet. Regardless, as soon as it got dark, Billy made the drone leave his home and made it fly toward the West. The speed was lacking, so it seemed that it would reach the demi-human continent after twelve hours, and unfortunately, Billy would have to guide it during the whole time.
"I guess this isn't half bad since I made it as light as possible and it is only consuming one point of mana per second," Billy thought. "In any case, I really need to find a way to make the flight automatic. I suppose I can control the wings of the vehicle with Telekinesis and then make the drone gather mana while it flies and between fights. The only problem is that I need to program it to work by itself to fly…"
That was something Billy had to consider before making the next drone. Nevertheless, he kept thinking of some improvements while he controlled the first prototype to the enemy territory. After a full day, it finally reached its destination and the drone was already flying forty kilometers above ground level, and yet… the gravity still was affecting it. Eventually, the same beam of energy was fired, and it hit the drone before Billy could see anything.
"Well, that sure was fast…" Billy thought.
Billy's other tests after making prototypes and adjustments… In the end, he also all the drones, and it seemed that the enemy could spam those attacks.
