勇者

When a young man from a remote village reaches adulthood, it's time to embark on an adventurous journey to fulfill a fateful mission: slay a dragon.
Dragons dwell at the summit of the mountain, eager to capture princesses.
To reach the summit, the brave must traverse forests, snow-capped mountains, and deserts. It's no easy task, requiring you to defeat countless monsters and solve countless puzzles. An elder known as the "Wise Man" will guide you with his wisdom until the end.
Of course, don't forget to help the villagers, as the brave are the embodiment of justice and courage.
The villagers will reward your kindness, and perhaps even a small favor will solve a crucial problem for you.
When you reach the summit, the true decisive battle begins.
Don't panic. Remember the combat techniques you've learned along the way, and be careful to dodge the dragon's flames. When the dragon collapses, you've won.
Congratulations, brave! You've achieved a happy ending.
