Capítulo 23: The Adventurer's Mark

As Leo was about to leave, Mr. Aizen handed him a folded piece of paper. "Take this," Aizen said. "It's a letter of introduction. Give it to any guild you join, and it will serve as validation of your strength and credibility." 

Leo accepted it with a nod of thanks, tucking it securely into his pocket. He then began his journey home. 

Passing through Chanter Forest, he noticed the lack of high-level monsters. Only low-level creatures lurked along the path, none of which posed any threat to him. Using his **Aura Skill**, he dispatched them effortlessly, watching as his skill leveled up to **Level 2**. He smirked at the progress, realizing that even minor battles could contribute to his growth.
