Thanks to Frost Lord's unprecedentedly severe warning, Wang Wu crawled out of the hollow trembling as if walking on thin ice. He cautiously observed his surroundings, feeling that nowhere was safe.
In truth, he was not simply scaring himself.
He truly felt his hair stand on end, as though thorns were pressing against his back.
So after exposing his head from the hollow for only a moment, he shrank back inside.
After thinking it over, he decided to wait another thousand years. During those thousand years, he would use Yin Fire and Evil Wind to evolve the demon cores of the First Sequence.
It was worth mentioning that evolving Yin Fire and Evil Wind did not mean they could only be paired with the Creation Fire Spirit Pill and Creation Wind Spirit Pill. Other options would work as well, but those two Spirit Pills were the best choices and offered the greatest advantages.
True Three Calamities evolution required the evolution of every power in all three sequences.
It was a long road.
Thus, the evolution of the First Sequence's demon cores gave him a blow to the head, just as expected.
Though it was not as despairing as using a Wood Spirit Pill to evolve Yang Thunder, it was still unbearably slow.
