I have cut out my master's heart and taken blood for seven hundred years to help him cultivate the ruthless way.
Until he brought back the blushing girl.
When she had a heart attack, my master opened my chest with his own hands and said, "I will give you your heart for hers temporarily, and I will give it back to you tomorrow."
But the next day, they stood hand in hand in front of my bed and said, "Now that it has been taken out, it is an ownerless thing."
I smiled and crushed my heart: "Master, the ruthless way you have cultivated... Can never be perfected."
