He had come so far, solving the intricate riddles and overcoming various challenges to reach this moment. The treasure awaited him on the other side, but he couldn't shake the feeling that this last door held something significant—something more than just riches.

Alex took a deep breath and reached out to touch the door. As his fingers made contact, the door shimmered with a golden glow, and the riddles began to appear before his eyes.
