From the Start, I Refined My Master into a Pill

"Wretched disciple, how dare you try to kill your master?"

"I dare."

"I raised you for eighteen years. Without me, you'd have been dead long ago. Ask yourself: how have I treated you all these years?"

"For these eighteen years, you've treated me better than your own son, better than you treat yourself. You're the kindest person in the world to me."

"I'm sorry, Master. I'll break both your legs first. Once you're inside the pill furnace, you'll be able to stretch out all you like."
