When he woke up, Li Xiu traveled to the steam age of the parallel earth, and he was an ordinary little detective with a bunch of younger siblings at home.
When he first came here, his partner and boss died miserably because of something strange. But now Li Xiu has to fend for himself in order to support his family. However, as a newcomer and encountering unknown circumstances, people not only distrusted him, but also feared to avoid him.
Fortunately, he brought a demon horn with him when he passed through. He wiped it casually, but unexpectedly, he summoned a demon.
"Your Highness, the Herculean Demon is at your service," the devil with horns bent down and said respectfully.
Invisibility demon, wall-penetrating demon, teleportation demon, Li Xiu discovered that he could even summon the demon king as long as he wanted.
With the help of the devil, Li Xiu's detective agency became an instant success and quickly became popular. But because the business was so good, he offended too many big shots, which finally led to bloody revenge.
"Suffer death, Li Xiu, you have been captured...?" The heavily armed killers screamed one by one as they looked at the sudden appearance of the 100,000 demon army.
