Nearly ten hours had passed.
The night of the real world, the day of the disaster world.
The daylight had darkened to the utmost, and in the thick cloud-like black-grey mist above, ash was continuously falling like snow.
At the southwestern corner of Ash City, not far from the city gate, sat an enclosing wall.
Two silhouettes stood amidst the ruins.
In front of them, the surface of the thick enclosure wall was gradually growing a swirl-like pattern. There was a faint tendency of forming a mysterious tunnel.
According to the task intelligence from Black Rain Villa, markers would arrive at Ash City through a disaster tunnel from the real world. Then, after twelve hours, when day and night once again interchange, the disaster tunnel would appear in the area of Ash City. Markers would return to the real world through the tunnel.
This is the generally normal way to travel between the surface world and the deep world.
