Chapter 700: Chapter 666: Sacred Blood Becomes Mortal Womb

The body of Chi Jiu, solved an urgent problem for Xu Ke.

That was, with the increasing number of Exotic Beast species, the initially six skulls used as a breeding vat had been steadily exhausted.

While Chi Jiu existed as a single entity, the personalities of its nine heads were quite different.

Maybe, it was these unique biological traits that allowed the raised Exotic Beasts to evolve in countless different directions.

If the cultivation material was replaced with other equal-ranked Demonic Beasts, like that brown giant peng, it might not have such results.

So, you could say the arrival of Chi Jiu was timely.

In Xu Ke's calculations, once the number of existing Exotic Beast species reaches a certain threshold, even without the flesh and blood of Chi Jiu, relying on the large numbers of Exotic Beasts themselves would be enough to sustain their self-propagation and evolution.

Therefore, next, Xu Ke shifted his focus onto how to manipulate these Exotic Beasts.
