At that moment when Mo Qian Yuan had tumbled over, she could pick out a faint floral scent, one that she was very familiar with. In the previous world, there was a type of flower and the extract of that flower could be made into a type of drug. If a person was taking that drug, their clothes would have this faint floral scent on them.
After taking this drug, it would make people all floaty and happy, throwing all their problems away. If taken long-term, it could change a person's mental capacity. If a person ate it for an extended period, he would turn into a waste very quickly as the drug not only damage a person's nerves, it also corroded their organs. Moreover, it was highly addictive and if not taken on time, it was as though there were hundreds of ants on them and this extreme discomfort could even cause personality disorders.
