Adventure and Advancement
Two months had passed since Kai and Zach's training began. They had worked tirelessly, honing their skills and taking on various quests. Their hard work paid off, as they both achieved C-Rank adventurer status.
Kai's progress was remarkable, his aura capacity increasing significantly. He now had four circles, a testament to his dedication.
Zach, meanwhile, had acquired a magical handgun to complement his self-defense skills. While he still couldn't use magic, the handgun provided a sense of security.
One day, Zach sought out Kai in their shared quarters. "Hey, Kai. Can we talk?"
Kai looked up from his training, curiosity piqued. "What's up, Zach?"
Zach hesitated, then said, "I think it's time we said goodbye to Sophia, Ryker, and Leo. We need to head to the big city, Eldian, to find a way back home."
Kai's expression turned thoughtful. "You're right. We've grown strong enough. It's time to take the next step."
Zach nodded, determination in his eyes. "Let's do it. We'll make a name for ourselves in Eldian and find a way back to our own world."
Kai grinned, a fierce glint in his eye. "Together, we'll make it happen."
And with that, the two brothers began preparations for their journey to Eldian, ready to face new challenges and forge their own paths.
