In the quiet room, the black crystal box in front of Lu Xuan began to tremble slightly without any warning.
Despite the surrounding space having no trace of wind, the box lid seemed to be gently nudged by invisible hands, slowly lifting open.
Inside the box, a mystical black tree lay quietly, about the size of a palm, appearing ordinary yet emitting an indescribable black aura.
And in the instant Lu Xuan lifted the box, a vast and endless black energy stream seemed to be released from its prolonged captivity.
The black energy stream surged forth rapidly, spreading out like a lightning storm.
This vibrant black energy stream came with a fierce momentum, seemingly about to break through the room's barrier and sweep outward.
However, at this moment, outside the room, a purple shield emanating a mysterious glow appeared in the air.
Like a giant purple dome, it tightly enveloped the entire room.
This purple shield was extremely resilient, exuding an incredibly terrifying aura.
