"Breaking the limit of the Black Tortoise Hidden Truth Art requires 2,200 black points." Mo Yun pondered briefly, then grinned. "Black-and-White Seal, let me see your limits!"
For him now, 2,200 black points were no more than a splash of water!
Without hesitation, Mo Yun fixed his gaze on the Black Tortoise Hidden Truth Art again.
In an instant, a tiny plus sign slowly appeared.
Mo Yun slowly exhaled, then extended his mental intent like a feeler and gently pressed the tiny plus sign.
With a muffled boom, memories both strange and familiar flooded into Mo Yun's mind like a surging tide.
Mo Yun held his breath and concentrated, carefully absorbing these memories and comprehending the cultivation insights woven into them.
After a series of changes, an unparalleled vitality force erupted from his body, instantly enveloping an area nearly a thousand miles around him.
At that moment, the area nearly a thousand miles around Mo Yun transformed from a winter of biting winds into a spring brimming with life.
Meanwhile, all the amber-colored jade liquid in his body had turned a deep blue bordering on black, resembling a tranquil, unfathomable lake.
The life aura contained in this jade liquid had reached an inconceivable level. Just a faint trace released from it could reverse the climate, spreading its influence across a thousand miles.
Sensing these changes, Mo Yun's face lit up with delight. "This Black Tortoise Hidden Truth Art really has something to it. No, it's no longer the Black Tortoise Hidden Truth Art..."
Mo Yun looked up at the notification that had quietly appeared before his eyes.
