"I guess this should be enough for the time being..."
Leon spent three days investigating the area around the mountain he first appeared. Although he hoped to find some traces of human activity, he found nothing. Three hundred years have passed, after all, so it was only obvious. Besides, considering Yuki's current behavior, it wouldn't be weird if Amanda and Hector decided to create another base far away from the purple crystal in case Yuki sends some 'visitors.'
Although Leon lost three days without finding a single sign of them, he learned a few spells. For the time being, they wouldn't be of any use against the hippogryphs, but Leon was confident of their potential. Cyclone was just a regular tornado, but it was made of water. Ignite was a spell like Frost Wave and Spark Wave, Leon shot a small ball of fire at the enemy, and then the whole target would start to burn. As for Earth Rocket and Fire Rocket, that was something Leon learned by chance when he tried to use Earth Lance and increase its speed using Telekinesis. It was a spell that would chase the enemies, no matter what.
"Hehe, it is very cool... but I don't have time to feel proud of my new spells."
Even though Leon was in a hurry to find Amanda, Maya, and the others, he started to wonder if it wouldn't be a good idea to have bought some clothes first while he was in Tokyo. Most likely, he wouldn't have been treated well, but he couldn't care less about that. Still... now that he wasn't in a hellish environment, he couldn't help but frown while looking at his current attire.
"I bet not even Amanda will recognize me... hell, there is even a chance that she also forgot about me. I can't blame her, though."
It was registered that everyone looked for Leon for ten years, but after that, there was no mention about him... at least on Japan's archives. Still, it wouldn't be weird if Amanda forgot about her brother... many things happened over the course of several centuries. Three hundred years passed since they left Earth... they probably left a lot of memories there, never to remember ever again.
Regardless, it was time to increase the scope of his search. In order not to overlook any sign, Leon would have to be careful. However, he couldn't just walk around or just run at his average speed. He would have to use his buffs, and that means he would have to keep Anti-Mana Field off.
Haste would be more effective, but Leon decided to use Electric Armor because it was a layer of condensed mana in a state that could be seen. If the lizard or the shadow bastard try to teleport Leon, it was very likely that Electric Armor would react in some way. That skill causes some damage to Leon, so he would notice in case that happens.

Although Leon had mana to keep Electric Armor active, he didn't have enough stamina to run all that much. Leon had to stop several times, but despite that, it didn't take long before he could find another purple crystal at the top of another mountain. Unfortunately, there were no signs of human activity nearby.
"If they went to another world, they probably created some camps nearby the purple crystal they used while they investigated those places... even after three hundred years, it was clear that some sort of trace would be left behind. Unless they created their buildings using magic alone and then got rid of them using magic in order not to leave any traces behind. That would be the most logical option to avoid pursuers or unpleasant visitors."
Technology didn't develop all that much on Earth because they found a dungeon that spawned the mechanical spiders. After investigating the world on the other side, they understood the dangers of it. So, instead of developing technology, humans decided to develop themselves physically and magically. Considering that, it wouldn't be weird if Amanda and the others had some sort of trick or spell to create decent camps and then get rid of their traces. That would be very smart of them but made things very complicated for Leon since it was like he was getting deeper and deeper inside an infinite maze.
"I guess I have to learn some tracking skills that grant me the power to search for signs of other people's mana. Mana Dominion can do that, but it only works on high and very recently concentrations of mana."
The best option would be if Leon could learn some skill that let him see mana clearly... but he had no idea how to learn that. He already had to use mana in his eyes in order to activate Sharp Eyes. Leon was in a bind, and he would have to find a way to do that before he explores that whole world.
