[Imagine the Ming Dynasty]
The following is the heroine's inner OS (mainly because I really can't write an introduction/(ㄒoㄒ)/~~):
My name is Feng Qingyao. I was inexplicably transported to the prosperous Yongle era of the Ming Dynasty, and became a miscellaneous maid of the royal chef.
But I have a system that gives rewards for tasks.
There are hypocrites in this court, and there are rivals who are trying to make things difficult for me.
Humph, I will not be knocked down. I will start playing the pig and eat the tiger that I am best at. I will definitely step by step from the lowest servant girl to the palace chef and get out of this system.

The protagonist has a golden finger:
System (publish tasks and give rewards)
Hierarchy system: Housemaid - Junior Cook - Intermediate Cook - Palace Chef
Intent: modern knowledge for ancient times
