The diary I wrote in eighth grade was exposed to the entire internet by that damned System, drawing countless netizens to gawk.
What Guanhang Ping found hardest to accept was that the damned System was trying to make the world match what the diary described.
When I wrote it, my consciousness as a transmigrator had yet to fully awaken, so I stuffed anything and everything into it.
And I didn't even bother to make it coherent. I just crammed in dark settings from things like Cthulhu Mythos and Warhammer...
Watching the monsters writhe out of the basement, Guanhang Ping suppressed the urge to kill himself, took the so-called reward from the damned System, and officially set out on the perilous path of an investigator.
PS: There are references to other works, but aside from A Certain Magical Index, they do not take part in the main plot.
