I Open an Intelligence Agency in Another World

I originally thought that traveling to another world was the beginning of Long Aotian's script, but it turned out that there were no plug-ins or systems. The only golden finger was the information gathering ability developed as a social animal in his previous life. In this world of swords and magic, I opened an information house and made a living by selling information. Until one day, an anonymous customer paid a sky-high price for information on "The Demon King is about to be resurrected."
