Zhou Mingrui transmigrates into the body of Klein Moretti.
After transmigrating, he even comes with a System.
That's normal. It's a setup that's been done to death in online novels for the last eight hundred years.
But when something this inexplicable happens, what can an innocent, powerless young man like him do?
All he can do is quietly follow the System's instructions, hoping to finish the mission early, clear the level, and go home, right?
And the world he's transmigrated into is an extremely niche blend of the Western Industrial Revolution and steampunk fantasy. The names are all long strings that give people from the Great Eating Empire a headache, never mind the food, which is impossible to get used to.
His only consolation is the System he brought with him. It isn't jumpy or cold and silent, but rather friendly and homey.
But the instructions the System issues leave him baffled:
"From now on, you must not use the Acting Method."
Zhou Mingrui has already realized he can't return for the time being and accepted becoming Klein. Just as he gets a crucial piece of information from the instance's hint item, "The Diary of Emperor Roselle," the System suddenly gives him this instruction.
Klein immediately grumbles to himself: Why not? Is this diary actually a trap set up by the instance to fool newbies like us?
System: Not at all. The Acting Method is the secret to advancing quickly and preventing loss of control.
Klein: Then if you won't let me use it, are you telling me not to advance, or are you trying to make me lose control and turn into a monster?!
System: You need to keep advancing without using the Acting Method.
In other words:
As a Seer, you can't gain revelations through divination;
As a Clown, you can't hide your true pain and sorrow;
As a Magician, you can't perform in public or push yourself to the limit;
Klein: If you want to kill me and start a new game, just say so!
System: Good luck.
Theme: As long as life goes on, keep striving.
