Within the Forty-Seventh Floor of the Tower of Myriad Heavens.
Li Hao appeared there through transmission.
The heavens and earth around were barren and desolate.
His eyes swept about, and he saw figures of Ancient Demons emerging one after another from the fissures ahead.
All of them were Fifth-Level Immortal Kings, their auras concealed but each belonging to the Royal Clan of Ancient Demons.
Now that there was no longer the urgency of the initial test, Li Hao’s heart was relatively calm.
Even if he failed the challenge, he could always start over again.
He glanced at the Ancient Demons, then returned his mind to himself.
“Three Realm Hearts… how can they coexist?”
Previously, with only two Realm Hearts, Li Hao had made them cycle alternately, maintaining a subtle balance.
But as time went on, after hundreds or even thousands of years, the two would begin to merge, leading to a flawed path, perhaps even a mistaken one.
“Failure isn’t frightening. At least, that rules out one wrong road.”
Li Hao spoke inwardly to himself.
Three Realm Hearts condensed within him.
His thoughts ran deep, yet he would have to verify them through practice.
Perhaps it would fail, perhaps it would succeed.
Once the bow was drawn, however, there would be no turning back.
“Hollow Heart Realm—embed it… in the Sword Dao!”
