Starting from a Mortal: Use the Martial Arts Sword to Kill the Immortals!

In this world, immortal cultivators are high in the clouds and regard ordinary people as ants and grasshoppers. A monk's talisman can cause thunder to wash away the earth; a golden elixir repairer can decide the life or death of thousands of armies with a single thought. Li Su, a border soldier who has no spiritual roots and cannot absorb Qi. In that battle of mountains of corpses and seas of blood, he should have died like dust. But he survived. In his cold amber eyes, the "power" of all things in the world can be clearly discerned. Since the Immortal Gate is closed and cannot cross over to mortals, I will use this curled blade of mortal iron to fight my way out! The rules here are simple: No matter if you are a land god or a reincarnated great power, As long as I take three steps closer - even a god will die! This is the story of a mortal swordsman, holding an iron sword, crawling out from the pile of dead people, and finally conquering the world with one sword and cutting through the Nine Heavens.
