Su Yingxue pulled out the letter left by her mother. Her mother had written about Saint Ruan, particularly detailing the records about the Intoxicating Fragrance, which essentially was Saint Ruan's romantic life.
Saint Ruan had exceptional talent as a young physician. He had a childhood sweetheart as his fiancee, whom he loved deeply. However, Saint Ruan was too wild and unbridled. Upon the prodigal's return, seeking to marry her, Saint Ruan discovered that his fiancee had married someone else.
This rejection devastated Saint Ruan. In a fit of rage, he poisoned his fiancee's in-laws to death. He even slowly poisoned his fiancee, desiring to make her suffer lifelong.

The Beauty-Stealing Poison was one of his proudest creations at the time.
For every ounce of pain inflicted on women, he brewed poisons.
