Tian Tianya Is Also Looking for His Owner Today

I am Tian Tianya, the magical weapon of the Western Dog General. After my master passed away, when the noble prince of the Western Kingdom who was supposed to be my new master saw me, he said, "What's the use of a blunt knife that can't kill people?" And left me. I became the scrap metal that no one wanted. There is no knife left here, only the place where the knife is left. I will definitely find a master who will not dislike me if I am born with teeth! Temporary owner No. 1: The crumbs of the world·Ghost King. Ghost King: "What are you for?" I thought about your young master's behavior and decided to hide the truth and stay here first. "I cut off people's heads and sneak away, and a hundred heads fell to the ground with a single wave." The Ghost King immediately picked it up and tried it on me. However, none of the members of the Demon Slayer Squad who attacked him were alive, so he could only target me at his subordinates. With just one blow, the subordinates were unscathed, and the remaining members of the Demon Slayer Corps were all alive and kicking. Ghost King:...... Looking at the livid face of the Ghost King, I knew that I was going to be abandoned again. Temporary Master No. 2: The Cursed King Based on the experience last time, I decided to tell the truth this time. The Cursed King: "Can you chop wood?" Me: "No." King of Curses: "Can you chop off people's heads?" Me: "No." King of Curses: "Then what can you do?" Me: "Let you get a second life." King of Curses: "Trash, how could I die?" Just when I thought this conversation ended in vain, the King of Curses left me behind. Me: "Do you realize my importance?" King of Curses: "I just don't think it's enough to kill all the spellcasters once, but twice." Me: "... Huh?" What kind of human devil is this! No, I have to go, I'm a good knife! Don't help the evildoers! Temporary Master No. 3: The Strongest Human Being Because of the previous experience, when I was picked up by a human this time, I planned to use it as a vase, no, an decoration. "My name is Tian Tianya, a dull knife that can't kill chickens or chop wood. If you have me, you will have the smoothest and clearest mirror." He picked me up and when he got home, he found his pregnant wife lying in a pool of blood, one dead and two dead. It's time for me to show off. "Please use me, Master!" Ji Guoyuan used me to save his wife, and they were grateful to me. I finally have a master who likes me. But later, Master Sesshomaru accidentally bumped into me and my master killing evil spirits, and snatched me from his hand without saying a word. "How can you, a human being, use my things?" Wait, when did I become your thing? ＊Short story. ＊The teeth are born into spirits and have human form. ＊If nothing else, the male protagonist should be Shadian. Intention: I have no control over my destiny
