Thank you for warning so clearly that it is better not to wake the dragon and make this adventure pure stealth to get out of the ruins undetected. Like Mission Impossible but with a dragon in the room, and with ruins instead of room. Perhaps, coming out of this one you can return in the future with a group of well-trained dragon hunters who can kill the dragon. But while we are alone and in the ruins it is better to follow the advice of the creator.
