A long time ago there was a big farm located on the outskirts of a bucolic city. A rather tall, red-haired man owned the farm. He was too grumpy for anyone to like him, he never shared anything with anyone and in the end of every harvesting season he would sell everything and keep all the money to himself. As a result, some other farmers decided they would destroy his farm, and do away with the red-haired tyrant. And it did happen, it was a beautiful spring day in the city, the farmer was having lunch alone on his porch when he spotted two men climbing over the walls trying to break into his property. At this moment, something unexpected happened..The farmer knew he would be attacked and set up an electric fence on the top of the walls. The intruders were not expecting that and as they reached for the fence they got electrocuted, falling dead flat on their faces. After that, the word spread around and no one dared to cross the farm's boundaries ever again.
bucolic countryside city - outskirts of a bucolic city. Countryside usually implies a rural area (of a city), so, an area outside of a city or town. Having said that, I think outskirts is a more appropriate word to convey your intended meaning
every reaping - Given the context, my educated guess is that you were trying to say (in the end of every harvesting season, he would sell everything and keep all the money to himself)
Harvest is the process of gathering ripe crops from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper.https://en.wikipedia.org/wiki/Harvesthttps://en.wiktionary.org/wiki/harvest
do away - I take you were using "do away" as in killing someone. You can't "do away" with "tyranny" because you can't kill tyranny. You can do away with the Tyrant though. If you were using "do away" as in "getting rid of something or someone" it would still weird to use " do away" as in "get rid of tyranny"
I would suggest picking another word in that case.
The man who owned the farm was rather tall and had red hair - Could also be said as: A rather tall, red-haired man owned the farm.
