In My Rebirth, I Am Just a Sword Spirit

Michu: What's going on with this light? Have I become a male god? System: No, you have become a male servant. Your master is this sword cultivator, and you are this sword. Michu: What a joke! How could a noble and elegant vampire be a servant to a lowly human being! System: Are you willing to follow this man, for better or worse, richer or poorer, in sickness or in health, to love and cherish each other until death? Are you willing? Michu: Let me out! System: Okay, you are willing. Congratulations on successfully activating the Sword Spirit system. Go say hello to your master! Chu Jin found that something was wrong with his Little Ghost Sword. It was his Horcrux and he could tell any subtle changes until he discovered the Little Ghost King inside... Chu Jin: I'm Chu Jin, whose child are you? Michu: ... How should I let him lead the dog? This is the story of a tsundere vampire who is reborn as a sword spirit and uses a system to help his master reach the pinnacle of life. (The arrogant foodie is attacked by a gentle and sinister person) Intention: Strive to stand at the highest point
