The gray fog descended, the old gods fell silent, and humans retreated to the last bell city.
Shen Ye traveled to the wasteland world and obtained an observation instrument that could "see the doomsday".
While others were struggling to survive in the gray fog, he was observing the trajectory of the gray fog;
Others were transformed into monsters by pollution, and he predicted the source of the pollution 24 hours in advance;
While others were waiting for a savior, he began to deduce the root cause of the doomsday——
"In one hundred days, the gray fog will completely submerge the last city."
The observer gave three clues: a key that did not exist, a person who had died long ago, and a clock tower that should not have existed.
Shen Ye had to embark on a journey to find the truth.
However, every time he uses the observer, he will be one step closer to the existence "in the gray fog"——
The being was whispering to him:
"The moment you saw me, I saw you."
