How Does Being a Lighthouse Keeper Make You Extraordinary?

[Steampunk + Extraordinary + Potions + Lighthearted + witty banter + a constant straight man + madness] Jiang Huan fell into the water while fishing in a wild lake. When he woke up, he found himself to be a lighthouse keeper in the steam age. Good news: I've time-traveled and now I have a job with a monthly salary that's equivalent to half a year's salary for others. Bad news: The workplace is a deserted island lighthouse, and my colleague is a damn old devil who's been dead for fifty years and is cursed, eating mushrooms every day. Check the buoys by day, fight off hallucinations by night. Whispers filled my ears, shadows loomed outside the window, and my diary was filled with madness. Until he discovered a mummified corpse, a bottle of "spiritual potion," and a talkative ghost trapped for fifty years beneath the lighthouse— When he finally managed to escape from the lighthouse, he discovered that he had become a thorn in the side of paranormal investigation agencies.
