I'm in Cthulhu, and the Ancestor of Fengdu City Asked Me to Make Money.

The Old Ones woke up from their endless slumber and cast their melodious and strange chants to the world, as if it was a sign of "their" return to dominate the world again. Goblins and ghosts wander around human cities, closely following the humans who are alone in human cities, always ready to open their bloody mouths and enjoy a feast. There are also believers who were dazzled by the red moon and drew evil magic circles in an attempt to welcome the coming of the evil god from outside the territory. … And Lu Xiao, as a time traveler, has Beiyin Fengdu as his back! Seize the creation of heaven and earth and proclaim the power of the Northern Emperor! Trade with Cthulhu, compete with the evil gods, kill the old gods, and establish the kingdom of gods! The eternal and unique plane of enlightenment is the incarnation of all things! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
