the title is a reference to one sword to rule them all.
okay mc meets god and decides to accept being reincarnated into legends of kora as a earth bender with a few perks witch first tophs earth vision witch even works on sand, next is the guaranteed ability to blend metals even metals with the highest purity and finnaly his own type of ultra instinct witch certain limitation like can only use certain moves if practiced at least a thousand for basic use to 1 million for master use while in a state of ultra instinct. oh yeah through in all knowledge of machines from his past life and a inventory but no system.
mc will wake up in the body of a ten year old in a field surround by mountains with a book next to him about bending.
mc starts his training while eating fruit and hunting the animals who where all herbivore.
mc training is the one punch training but nerfed. he does this while holding up a bolder with his bending. he also practiced his preciseness by making life like sculpture with metal and rocks. he also practice his ultra instinct by dodging hundreds of rocks he threw randomly in the skies. with him practised making amor using earth and metal.
sorry there I love training in air bending and erath is my favorite.
okay mc leaves on the same day Korea headed to the city.
oh yeah if any writers read this stop making the main character steal people girls I hate that shit and it a dick move.
hope you like my idea, comment if you do.
