The two men were walking along the edge of the forest. The sun was shining brightly over them, and it was warm enough to make Lucas wear only a thin shirt without feeling cold.
"Where are we going?" Lucas asked.
"We are going to search for something important," Luu explained, "but first, you need to know some basic rules."
"Like what?" Lucas asked curiously.
"When you travel," Luu told him, "you must always take care of yourself. That means that you have to eat well, sleep enough, and stay hydrated. If you follow these simple rules, you will be able to handle everything that comes your way."
"What else?" Lucas asked, "I thought we were just looking for food."
"Don't be silly," Luu laughed, "we will find food as soon as we are done here."
Lucas shrugged and decided not to argue further.
