Lu Zheng looked at Si Lingxi, "Have those four dragons already been harmed?"
Si Lingxi replied calmly, "That strand of Four Divine Demon Fires just now obviously wasn't the Fiery Heaven-Destroying Demon Dragon King's full effort in casting, for it could invade Ao Shen's body and entangle with him for quite some time until Ao Qian used the Jade Marrow Potion to drive it away, showing its extraordinary nature.
Only by refining a pure-blood Golden Dragon, or rather, a young pure-blood Golden Dragon who hasn't cultivated and is unaffected by external force, could it perfectly invade the Golden Dragon bloodline, integrate within, entangle without rest, and be so difficult to eradicate.
Since it's called Four Divine Demon Fires, the same situation applies to the missing young dragons of the Cyan Dragon, Azure Dragon, and Jade Dragon."
Upon hearing this, Lu Zheng looked towards the Black Water Lake's surface and couldn't help but express concern, "In that case, those dragons..."
