Hou Yiwei did not want to admit it, but Adrian's form really is much cooler than his. He did not disregard Adrian's warning as the one known as The Demon will not say something that will fool them. He immediately emitted a draconic roar as fire started to release from his mouth.
Hou Yiwei immediately transformed using another form that he has yet to show the world. He learned of this form from one of the elder dragons that actually wielded a sword. He thought that all dragons would be just proud great creatures that are masters of magic but there is one elder dragon that is said to have followed the path of the sword.
This elder dragon is also said to have fostered a child with a human once and they ruled a kingdom a long time ago. This elder dragon has a form that wielded a large sword and would use their draconic strength to oppress their enemies and that is the form that Hou Yiwei will use as well.
