"Limit of the First Stage of the Eternal Heart?" Li Yuan wondered.
"Yes."
"The Star God Cultivation System, known as the most powerful cultivation system, means that the willpower of the Divine Kings generally reaches the level of the 'Eternal Heart,'" Jin Yuan explained. "But for other cultivation systems or some Star Beast Emperors, their willpower may not transform upon reaching the Eighth Rank."
Li Yuan nodded unconsciously.
Indeed, within the Immortal Heaven and Earth, many low Rank Quasi-Saints can persist for hundreds of millions of years due to their strong willpower.
However, many Eighth Rank Cultivators who haven't broken the Path, even if their true self is entrusted to the Inner Universe Space-Time at the Emperor Realm, still struggle to survive for over a billion years in the Eternal Relics.
The main reason is insufficient willpower.
