A Sword of All Calamities

If you touch my brother, I will destroy your whole family; if you touch the one I love, I will kill you. He is sharp-tongued and unsentimental, attacking people directly to their pain points. It is normal to leapfrog and fight back. He never engages in "a gentleman's revenge is never too late", but only "revenges you on the spot". The sword never kills the innocent, only the unreasonable. If you encounter a situation where the rules are explained three times beforehand and the logic does not make sense, then use the sword to make the other party understand. He understands the ways of the world and has the atmosphere of the market. He will chat with the stall owner over a bowl of pork noodles, and he will also stand up to the entire fairy court to protect a mortal. Carrying the only sword body of all eternity, even if it is beaten to ashes and the soul is scattered, as long as the sword heart is not destroyed, it can be reborn from nothingness. And every time it is reborn, the memory of the previous life will be unlocked, the cultivation level will skyrocket, and it will survive thousands of calamities and remain undefeated. After waking up from the Sword Tomb in the Mortal Realm, he lost most of his memory and only remembered that he died thousands of years ago. He looks cynical, laughing and scolding, but in fact he is thoughtful and carries the last wishes of all the fallen gods and demons from eternity ago. He is the only chess piece in the battle plan that spans countless universes.
