December 23, 2020, it was drizzling.
Calculating from the morning.
There were less than 48 hours until Christmas Eve.
In John's studio, the incandescent light came on.
The curtains by the window were tightly drawn.
John stood before an entire wall.
He retrieved the marker from the wall.
He looked at the wall with bright eyes.
A map of Owain City that covered the entire wall appeared in front of him.
This was a highly precise non-civilian map.
Numerous routes intersected and overlapped.
Form, slope, curvature, layout, direction, and so on.
The data was very detailed.
At John's feet.
There were messy papers with calculations written on them.
On the map of Owain City on the wall.
John marked different routes.
Some of the intersections were clearly marked.
The environmental index within three days, including air humidity, wind direction, and rainfall were also written there.
