The ancient, deep-sea city of Nasaton was shutting down the large protective wall for the first time in 10,000 years. The translucent film above the city slowly crumbled and receded from the apex as well as spatial layer. At long last, the layered, invisible labyrinth was gone. With the shutting down of the wall, the maelstrom directly above the city gradually lost its energy supply. Its edge shook slightly and it began to spin at a slower speed. However, just as the siren queen had predicted, the maelstrom did not disappear. It was still unstoppable, still growing, albeit slowly.
Hao Ren led everyone back to the city's surface (in the deep sea, the word "surface" seems a bit weird). He looked at the maelstrom above, and it felt like the maelstrom could fall down at any time and consume them all. "Now we have a month to shut this thing down. I think it'll directly affect my year-end bonus this year... So, which one of you has a better solution?"
