Chen Mo was once an inconspicuous ordinary person in the bustling city. At the moment when time stopped, he was resigning and leaving the company due to some dissatisfaction with life. This sudden disaster threw him out of his ordinary orbit and became the "only active unit" selected by the "Paradox Engine".
From the initial extreme fear and confusion, to being forced to accept reality and explore for survival, he relies on the guidance of the engine and his own resilience to gradually uncover the terrifying truth behind the stop of time - the existence of "reverberation".
His journey is lonely and dangerous, crossing dead cities, climbing solid snowy mountains, and going deep into dangerous underground facilities. He encountered various horrific aberrations caused by time stasis, and also interacted with the remnants of the Seventh District and the survivors of the Hidden Snow Valley.
He obtained the key props "Observer's Pocket Watch" and "Phase Shifter" and gradually learned to use their power. He witnessed sacrifices (the clock watcher) and made allies (such as Ling Han, Xiao Dao). From a survivor who only wanted to protect himself, he gradually grew into a key figure who realized his responsibility and took the initiative to fight against "Echo" and its minions (messengers and hunters).
He is no longer an ordinary clerk, Chen Mo, but a traveler walking in frozen time and space, a "variable" carrying a faint spark of hope. Every decision he makes may be related to the ultimate fate of the world.
