Alternating Flow
Arriving at the mountain of the Alternating Time Flow Valley, Davis saw the steep slope heading downwards as though it was a roller coaster ride. He couldn't help but blink before turning to look at a warning sign stabbed into the surface of the peak.
[You could find yourself losing lifespan quickly in this training grounds, which is practically a danger zone.
