The next day.
Morning.
It was the 4th day of the new year.
After a tiresome night, Zhang Ye crawled out of his bed and took a peek through the gap in his curtains. He realized that it was already bright outside. It was not natural brightness of the sun, but rather a kind of reflective type that didn't seem natural. It was around 7AM and was not a time when the sun would be shining in. He unwillingly threw aside his blanket and stretched himself before walking towards the curtains and drawing them open to take a look outside.
Oh!
It was snowing!
The snow was reflecting the sunlight. No wonder it looked different from usual daylight!
