Tanya was learning within the Volkov family division of the Petrova family where various resources were available to them to learn military combat tactics and other skills.
Books and other resources were available to anyone willing to make use of them for the sake of the Petrova family.
Tanya lost her previous life memories serving the Empire due to the influence of 'Being X' but she did not lose her memories from before that as a Salaryman.
She was able to analyze many patterns within the military funding books and other related records so she quickly found many concerning points that suggested corruption was present.
She could not bring it up since she was just a child who few would listen to but she did write a report that was given to Captain Rich.
He had more sway when it came to getting others to respond to him so Tanya did not mind passing over part of the credit to him.
The report included possible predictions based on the progression of the state of the Vodka Kingdom if things were allowed to continue down the current path.
It included wasted funds spent by nobles, disappearances of smaller businesses, rising crime, and many other effects that would progress as the situation worsened further.
If production and other fundamentals that supported the kingdom were corrupted and were lost, the foundation that supported the kingdom would cause the kingdom to fall apart.
A kingdom that kept taking from others and did not know how to support itself had no future especially when it was still at war with other organizations, pirates, and other nearby islands.
Lev Petrova approved of the plan put forward by Captain Rich so in exchange for the credit, Tanya was allowed to participate as she was put into a position where she could observe and report everything illegal going on.
Some guards were taking bribes to let some people enter the city which should have been stopped while criminals were able to do as they pleased without fear of being punished.
When it was the right time, Tanya and others finally made a move.
