Capítulo 1039: Tekur Blood

"The Red Dragon destroyed Nest Six in the western region. The Dragonbound collected the deceased and looted the warehouses with your Plunder Crystals!" 

The Dragonbound were ordinary Summons with a high affinity toward heat, animals, and mythical beings. To be precise, the Red Dragon liked them a lot. The Summons played with the Red Dragon and treated her with great care. They did everything she wished for, which was also why she issued the request to fly with her caregivers into battle. 

Michael and others rejected that proposal because the caregivers weren't powerful Summons at the 3rd Tier or higher. They couldn't resist the purgatory flames of the Red Dragon and would die from the heat. Even if the mythical flames weren't close to them, they would burn and kill the Summons.
