I Called the Devil a Scumbag, but He Cried and Begged to Get Back Together

Others rely on meditation to cultivate immortality, while I cultivate immortality through talking. I got the magic sword by scolding my mother, I got the immortal armor by scolding my father, I called the devil a "scumbag", and he cried and called me husband. The whole world thinks I am a grumpy old man, but only the Demon King knows that - the harder I scold him and the higher my cultivation level, the more he loves me.
