Wang Daoyuan had truly never heard of such a situation.
Generally speaking, it was extremely difficult for Demon Beasts carrying divine beast bloodlines to raise even a little of that bloodline.
If not for the Spirit Pearl Space, one with blood as thin as Yun Yi's would never have been able to break through to the fourth rank in this lifetime.
Dragonfish like Wang Minglong and Wang Xuanlong would already be fortunate to cultivate to the fifth rank.
