Manga (manhua) of the day:

I’m Really Not the Demon God’s Lackey

Status - Ongoing

A completely normal (the eyes are watching you) bookstore where lives a completely normal bookstore owner (the books contain knowledge so forbidden you would go insane) that uses his knowledge on psychology (and eldritch terrors) to help people who came here (you may go insane from books he gives but you will sure receive a nice power-up and a very vague advices)

Kinda getting Max Frey books vibes from it, but with more gore and horror in it + ignorant MC that illustrates that by talking with just enough vague phrases you can look like a smart person (or eldritch god). Not a fan of gore, but story is interesting enough to read all available chapters in one day.
