I founded Tantric Buddhism in London

He thought he had traveled back in time to the fictional Victorian period and was thinking about how to live a wonderful second life, but he never expected that after being introduced by a friend, he met Charlotte Holmes...Miss!
Okay, so it turns out to be the world of mystery novels... which is kind of interesting.
However, as the investigation of the case deepened, he was surprised to find that there were actually supernatural powers hidden behind those incredible cases!
Uncovering the secret history beneath the surface of the world, the noon and the night, the nine principles, the invisible technique, a strange hunger and thirst overwhelmed him.
………………
As soon as he walked into his family's bookstore chain, Charlotte, the famous detective and duchess of London, chased after him.
"Watson, I need your help!"
"We have worked together to detect so many bizarre cases, destroy so many evil associations, and free Fog City from the control of the Tuosichens."
"But recently I discovered that this is not over yet!"
"There is still an extremely secretive secret order lurking in London. Its power is as wide as a big net that tightly wraps the foggy city. The dangerous characters we have defeated are just small minions compared to it, even if they are as terrifying as Moriarty It’s hard to compete with it…”
"Watson! Let us fight side by side again and restore peace to London!"
After he comforted her and promised to help her defeat this evil underground organization, Miss Holmes, who had not fought alongside him for a long time, left with satisfaction.
At this time, a graceful lady walked out of the door behind the bookstore. She groveled and said enthusiastically:
"Leader, the ceremonies of all branches are ready, just waiting for you to ascend and achieve great achievements!"
