For example, in the first 1 issue of Harry Potter and the Sorcerer's Stone in this series, in the opening chapter 6, when Harry and Ron are on the train to Hogwarts School of Witchcraft and Wizardry, Harry invites Ron to eat chocolate frogs together, and Ron shows him a small card attached to the chocolate frog, which has such a description:
"albus dumbledore is recognized as the greatest wizard of our time. Dumbledore is the headmaster of Hogwarts School of Witchcraft and Wizardry. His well-known contributions include: 1945 defeated dark wizard Grindelwald, discovered 12 uses of dragon blood, and made great achievements in alchemy with his partner Nicolas Flamel. "
It can be seen that dragon blood is a very widely used and important magical substance in Harry Potter's world.
For example, in the sixth harry potter and the half-blood prince in this series, in the fourth chapter, when Dumbledore took Harry to visit Horace Lagerhorn and invited him to be a potions teacher, Horace deliberately set up a fake scene where he was murdered. The so-called "blood" was made of dragon blood:
……
"By the way, what blood is that?" Dumbledore asked, louder than the pendulum of the newly repaired floor clock.
"On the wall? It's dragon blood. " The wizard named holas answered loudly, and then what? That? The chandelier jumped back to the ceiling automatically, and the creaking tinkling sound was deafening? Deaf. ?
As the piano finally sounded, the room finally quieted down.
"Yes, dragon blood," said the wizard Tan Xing very firmly. "My last bottle is surprisingly expensive at present. However, it may still be valid. "
He walked to the sideboard with heavy steps, picked up a small crystal bottle on the top of the sideboard and carefully looked at the sticky liquid in it under the light.
"Well, it's a little dirty."
He put the medicine bottle back in the sideboard and sighed. At this time, his eyes fell on Harry.
……
This description also proves that dragon blood is a very valuable magical substance. At the same time, according to our imagination, in Harry's world, dragon blood is a red viscous liquid, perhaps similar to the shape of human and mammalian blood. The role of dragon blood has been mentioned many times in the magic novel Mercenary World, the masterpiece of famous online writers.
For example, in Chapter 56 of Volume IV, there are the following descriptions:
"... after returning to the magic empire, the magic emperor and several elders at that time joined hands to rebuild a mud dragon from the land of heaven, pushing the dragon's blood and ideas into the mud dragon. This dragon is as powerful as the sacred dragon ... "
