Although the number of things Leon wanted to learn increased, he didn't feel bothered by it. The more skills at his disposal, the more problems he will be able to solve when the time comes.

Just as Leon had expected, making several wounds heal at the same time was hard. Still, he had no choice but to keep trying. It was the only way to find a clue about how to regenerate lost body parts.

Leon and Lennart arrived in San Diego soon after sunset, and they didn't waste time and flew toward Las Vegas. The kid was so eager to see Gisela that Leon was already tired of seeing his eyes full of expectations. They arrived at Las Vegas around midnight on time to see a tired Amanda crossing the garden and everyone, but Maya waiting for her. When those two suspicious figures appeared, everyone jumped and prepared themselves, but soon they recognized Leon.

"Bro… ther…" Amanda said with her eyes wide open.

It looked like the news hadn't arrived in Las Vegas yet, so they couldn't help but froze on the spot when they saw Leon's body. If it were any one person, they would think that was a joke, but they couldn't even think of that in such a moment. The only person who didn't read the mood was Lennart, the moment he saw Gisela, he jumped into her arms. She got confused, but after a brief conversation, she recognized her little brother's voice.

"…It looks like a lot happened." Hector said, showing a serious face. "Let's talk inside."

It was late, but everyone wanted to hear what happened after Leon left. In the end, they regretted not going with him; if one or two had gone with Leon, they could have prevented Makoto's death and Leon's injuries. They didn't insist because they thought that would annoy Makoto. They didn't know that he wasn't the type of person who would refuse the help of those who Leon trusted.

"I failed big this time… I failed so much that I feel guilty by receiving Makoto's katana and Yuki's magic box." Leon said. "Although I didn't ask for it, the new Russia leader even gave me the railgun."

"To think that master would meet my little brother," Gisela smiled. "Thank you for bringing him to me, master."

"… Master?" Lennart's eyebrows twitched.

"… Don't look at me like that, kid." Leon sighed. "I told your sister to stop calling me that hundreds of times."

Lennart wasn't satisfied with that explanation, but he decided to shut up for the time being. It was late, and he was at Amanda's house, so it wasn't the time or the place to start an argument, much less when he just reunited with his sister.

"Anyway, did something happen while I was away?" Leon asked.

"Not much, I just learned the hard way how tiring is to teach magic to so many people." Amanda showed a weak smile. "Sarah called a few days ago to inform that they will have a hard time replicating those choppers… aside from that, nothing."

"I see… well, I will talk with her tomorrow." Leon said. "By the way, the Angelic Bow is yours now. It belonged to Alexei, but now that he is gone, no one will complain. Speaking of the bow, how are things nearby the demons' dungeon?"

"Everything is fine," Amanda said. "Now and then we go to the dungeon to decreased their numbers… but soon, a dungeon break will occur."

"I wanted to spend a few days of training, but I guess I will clear the dungeon," Leon said. "I wonder if we can find the devil himself on the other side of the dungeon…"

"Don't even joke about going to the other side," Amanda said with a harsh tone.

"I'm just joking." Leon chuckled. "I truly want to spend as much time as possible, finding a way to regenerate my limbs and Gisella's eyes."

"Come to think of it… aside from the fact that you got hit by a railgun, you look awfully fine." Hector frowned. "I can't even see the marks of burns."

"I healed the burns, and I also learned how to heal wounds," Leon smirked. "Wanna see? Who is going to be my guinea pig?"

Everyone was afraid of Leon's cold smile, but Hector easily cut himself with his spear. It looked like he was quite used to pain… to make his sister worried face disappear, Leon healed the wound in an instant.

"I will try to teach this skill from tomorrow onward, but I don't think it will be easy," Leon explained. "However, even if one percent of the survivors here learn the skill, we will be able to decrease the casualties by manifold.

"Amazing… I barely learned one spell this month, and you learned two very convenient spells." Betty said, astonished.

"It may be hard, but I think every soldier needs to learn it," Leon added. "If they learn Heal, they can close wounds in an instant, and they would be able to fight for a long time. This will be our best weapon against the hordes of monsters… Now that I think about it, I can use this knowledge to make the other nations become allies."

"Ah… if you tempt them with the power to heal wounds, they will probably accept your offer." Hector said. "The problem is, will they continue being allies after they learn the skill?"

"That is no problem," Leon smiled. "If that happens, by the time I will have already learned the skill to regenerate my limbs. Then, I will show them how well I treat traitors."
