That’s the spirit. In a pinch, you could always use the calculator app on your cellphone.
Anyhow, the next step is to hire dacoits. This is important, because if you are an absentee landlord, enterprising peasants and rival landlords would try to usurp your land. They will try to do this anyhow.
Dacoits are a smart hire because unlike hired thugs drawn from country yokels, dacoits can supplement their income with organized acts of larceny. Said acts can help you strategically too, to keep any recalcitrant rivals in check.
You will need to build a dera for the dacoits. This is a brick building, suitably unfinished and nondescript. This is where your band of heavies will rest, recuperate, eat, frolick, etc.
A word of caution. There is a lot of intrigue that goes on in the rural underbelly where these people operate. You will need to keep your ear to the ground, root out any traitors and turncoats in the midst, and deal with them with an iron fist.
