Became an Archmage That Possessors Were Obsessed With

In MC’s modern world, thousands of people disappear mysteriously. At the same time, there was a message board where people post about how they are possessing certain novels. People didn’t believe them and when the posters tried to post proof it was censored. However, the MC thought it was real, so he looked into the novels the posters supposedly possessed, and spent two years reading around 1400/3000 of the ones he identified, just in case he was ever in their situation. And eventually MC is possessed, he gathers cheats/hidden pieces, learns magic, participates in wars, he becomes one of the people using the message board.

Story starts after MC becomes a Grand Mage, he gets Admin rights. Now, it’s about him being able to visit the other message board users in their other novel worlds while he helps them and resolves his own PTSD.

It’s fairly decent, MC saves other posters and brings them back to his world (they are the harem), but MC isn’t really interested in romance. There was a fantasy race war in MC’s novel and he had to kill a lot of people with magic, so romance is the last thing on his mind. I’m ok with gallery novels, one thing about this is that there aren’t whole chapters dedicated to the posts, just a few paragraphs. It seems as MC helps out other posters, he gains more power over the message board, and eventually he’ll find out why it exists and what the goal of the message board creator is, or at least that seems to be the trend.
