After Neville burned the White Dragon's heart, Linora immediately turned the ashes into medicine. She worked quickly and meticulously, racing against time to keep Ruby from losing her life.
"This kind of medicine has only been considered a myth for thousands of years, so there is not much knowledge about how it works," Linora explained to Matthew while her hands were busy boiling the medicine. "However, according to my limited knowledge, you can be unconscious after taking this medicine."
"For how long?" asked Matthew.
"That depends on your body. It could take around two to seven days." Linora sighed, frustrated that her knowledge was so limited. "I'm not so sure."
She wasn't even sure if the heart was really capable of binding two different souls. If the medicine failed, she would not be able to save Ruby's life, which was already on the brink of death.
"The medicine will work, Miss Archer," Matthew insisted.
