Whoo...
Black Fog surged, and the cold wind howled.
Inside Black Wind Camp.
Yu Hong stood in front of the outer courtyard fence, waiting for the completion of the Black Mark enhancement.
He didn't wear a helmet, just a simple breathing valve, his gaze fixed on the fence.
One minute.
Five minutes.
Ten minutes.
The countdown abruptly zeroed out.
Swoosh!
In an instant, the entire perimeter of the camp blurred, the fence disappearing all at once.
Following that, in the next moment, a three-meter-high, more than one-meter-thick, stout heavy stone wall rapidly materialized where the fence had been.
The stone wall, like the fence, circled and was constructed around the camp. Its surface shimmered with layer upon layer of dense and intricate rune white light.
The white light flickered only once before quickly dimming and receding into hiding.
Soon, the stone wall completely solidified, leaving a thick stone gate at the position facing the driveway.
