Reincarnated and Become Most Lucky Man

What would happen if you were reborn in a different world? A world that has just ended the era of war?? The world has an area 2-3 times larger than Earth. With fewer humans living in it, the world still has many mysteries to uncover. And Arjuna experienced that, reborn in a body that had the same name as himself, Arjuna was shocked to find this era full of flaws! Where humans need rations to eat!! Purchasing items requires a ticket!! And the atmosphere of the early 50's era is very earth-like. Just as he was preparing to blend in and accept his life, he was again surprised to find an emotional system that came to accompany him. Pleased with this, Arjuna was surprised again to find that several of the protagonists in novels and films he knew on earth were also here. And once again he was surprised again!!! What world is this!!! Why is it so messy but full of mystery!! He couldn't wait to explore it, only then did he find out that there was an extraordinary rule that he admired, in this world polygamy was legal because the number of men had dropped drastically due to dozens of years of war. So now Arjuna releases all his traits and prepares to conquer and make a new mark in this world in his name.

So Arjuna decided to protect himself and his women, he fought and fought with them to gain victory. Until one day Arjuna succeeded in establishing his own power and ruled almost the entire world under the banner of his power. And from there the legend of a handsome ruler who was evil and charismatic began…..(this is the enemy's point of view as for Arjuna and his woman, clearly he was a good hero)
