In 2077, the "Bliss Project" was launched, and 99% of humans abandoned their bodies and uploaded their consciousness to the quantum cloud, gaining eternal happiness and life.
In this abandoned and dilapidated reality of the earth, Chen Mo is the last generation of "offline detectives". He guards the old server room and relies on server maintenance in exchange for meager survival resources.
Until one day, a "god" in the cloud, the founder of a certain technology giant, "died" in the absolutely safe digital world. His data was completely wiped, as if he were actually brain-dead.
Chen Mo received a commission and had to sneak into that bizarre digital paradise with his physical body. He discovered that the so-called immortality was just a lie, and that a virus called "Forgetting" was being generated in the cloud world.
And all the clues point to an astonishing fact: the real world has long been destroyed, and Chen Mo himself may be the only "brain in the vat".
