Eleanor (Noah), a daughter whose engagement was broken off by the prince, fell in love with alchemy and rose to the rank of state alchemist. However, she bought the prince's resentment for the death of her sister, who was betrothed to her prince instead of herself, and was released from her punitive force. In order to avoid her crisis, Noah decided to pass the time by applying the "three-year sleep" technique to herself. However, when she wakes up from her sleep, for some reason, there is a nightmare-like world where alchemy is obsolete, the sky is dyed red, and beastmen are rampant. "What happened in your sleep?" Noah realizes she woke up 300 years into the future. Her destiny will be carved out by her own hands-the story of alchemy daughter Noah begins here!
