As Shi Feng chose to replace his original Mana Body in the secret chamber, the mana density throughout the chamber instantly dropped to almost nothing. Not only was the mana in the secret chamber drained away, but even the mana from the deep void rushed into the Mana Body in one great surge.
The new Mana Body was like a starving beast, frantically devouring the surrounding mana and constantly filling itself.
Only after this continued for more than a full minute did the phenomenon stop, and the mana in the secret chamber gradually began to recover.
"Tier 5!"
"So this is the power of a Tier 5 class?"
Feeling the terrifying power he could unleash with every gesture, along with an indescribable sense of omniscience, Shi Feng finally fully understood why even Tier 4 experts capable of forming a World at a Thought could not defeat a true Tier 5 class.
He also fully understood the strength and terror of a Tier 5 class!
Compared to Tier 4 classes, Tier 5 classes possessed vastly denser mana within their bodies. Their total mana exceeded that of Tier 4 classes by more than tenfold, so much so that even the entire world struggled to bear such mana.
Even the world of God's Domain could not withstand this incomparably powerful mana, much less the World at a Thought displayed by Tier 4 classes.
Moreover, this was not the only remarkable thing about Tier 5 classes.
