While the wyvern prayed that Arias would never return to the Dragon King's dungeon, it had no idea that Arias and the elder gnome were planning to create a direct portal connecting the Celestial Garden with the outside world. As the guardian beast of the garden, Arias would undoubtedly visit it many more times.
If the wyvern were to learn of this news, who knew what expression it would wear? Most likely, it would be one of utter despair. Its entire body might even tremble in fear.
The reason the wyvern was so terrified of Arias wasn't just because Arias had once brutally beaten it, but because it sensed that Arias had grown stronger—much stronger than when he first entered the Celestial Garden. He had become so powerful that the wyvern's strength couldn't even compare.
It’s natural to fear the strong, especially those who are merciless and cruel in their attacks.
