The knight king of the otherworldly moon

Hundreds of years ago, the Holy Unified Empire was divided into nine by civil strife.Britain is one of them.The one who draws this sword is the King of Britain, which is a legend left by the British generation.The king is determined by the sword of the king.Then, the king died...To put it simply, a certain transmigrator was reborn into a new world after being fooled into becoming the King of Sin and burning himself, but... this world seems very strange.Protagonist: Fuck you, I don't read much, so don't lie to me.Charlemagne and Alexander were heroes at the same time?Well, I'll take it.But what happened to Babylon's Wink and the island nation's Nobunaga? When Babylon disappeared, the island nation's people were still hanging on trees as monkeys.You tell me they are a product of an era?However, the Dummy King is still cute.Finally, can anyone tell me why I can draw this sword in the stone?
