"To be honest, I was more concerned about the 'Eternal Night' Song Yarong mentioned, the one that covered the entire Shu Province region," Sun Hang said.
This was Sun Hang's first encounter with an anomaly ranked within the top three by serial number—and it was a Phenomenon-type anomaly, second only to Type A - Rule-based anomalies in terms of difficulty.
Although serial numbers could not fully represent an anomaly's strength, any anomaly ranked in the top ten, regardless of category, was never something to take lightly.
Whenever an anomaly with a single-digit serial number appeared in humanity's sight, it meant disaster was about to descend.
"The last time 'Eternal Night' appeared was in Year 4533 of the Yellow Calendar. It covered the entire Hexi Corridor, along with more than half of Liangzhou," Ye Xuan said gravely.
"4533? But Song Yarong told me Eternal Night disappeared a hundred and thirty years ago..." Sun Hang frowned, realizing the problem. "Don't tell me the Eternal Night that appeared in 4533 lasted over fifty years?"
"To be precise, fifty-five years, nine months, and twenty days," Ye Xuan said. "It began on September 12th, Year 4533 of the Yellow Calendar, and ended on July 2nd, Year 4589. According to historical records, the entire Hexi Corridor saw no daylight year-round. Vegetation withered, plagues ran rampant, and venomous insects and ferocious beasts roamed unchecked. Of the four cities of Hexi—Xiliang, Suzhou, Ganzhou, and Shadu—nine out of every ten households were emptied, and the number of refugees reached the millions."
"This time, Eternal Night won't last decades too, will it?" Sun Hang asked quietly, glancing at the night sky beyond the cabin.
"I don't know." Ye Xuan shook her head. "The longest recorded Eternal Night lasted more than three hundred years, while the shortest lasted only four months.
