So many history related stuffs are missing in this manga regarding Genghis Khan but i think it's more like emotional journey of him going from knowing his blood related brother to kill him , what's actually real is that to know about a ruler that killed millions and ate many people during his journey and attacks countries at night to be called supreme ruler or Khan , during 120 AD no people fight in hiding manner as much as Mongolian's tectics of battlefield was it's easy to attack a country unprepared than to fight full armed plan, it's shortly related manga it doesn't even show how much he go through and become ruler how his stupid 4 sons were useless that's why empire collapsed after his death, it short but i think i like it.
