"Rumble..."
After the ground shook violently, the sky suddenly grew dark.
Anticipating such a change, Zhu Yun and his two companions paid it no mind, continuing their actions without pause.
A few breaths later, dazzling light burst from the three jade tokens, illuminating the entire land brightly.
Upon witnessing this, Zhu Yun and the others shouted into the void.
"Activate the Tianfeng Wind Secret Realm!"
In an instant, their faces turned exceedingly red, and beads of sweat the size of beans continuously dropped from their foreheads.
Clearly, activating the jade tokens to open the secret realm consumed a great deal of spiritual power; otherwise, even Golden Core Cultivators wouldn't struggle this much.
As time slowly passed, the glow from the jade tokens grew ever more splendid as True Essence Mana from within the three of them poured in.
Eventually, it seemed the True Essence Mana absorbed by the jade tokens reached a certain threshold.
