Daring to rebuke the Supreme Demon Lord, that's truly living impatiently.
If the Supreme Demon Lord wants to kill, not to mention a Heavenly Emperor, even a taboo existence would pale.
The Golden Crow Ancestor slapped him, which was just acting on behalf of the Supreme Demon Lord to teach him a lesson, so the Supreme Demon Lord would not have to act.
After all, he is a taboo existence, still needing a bit of face, and wouldn't easily bicker with a Heavenly Emperor.
"Is that so? Do you really think I would worry about those things? Back in the days at Heavenly Desolation, I came and went as I pleased, killed and exited multiple times. You useless people think you can threaten me?" The Supreme Demon Lord laughed, very disdainfully.
Jin Yu was startled, the Supreme Demon Lord had actually slaughtered his way into Heavenly Desolation, and even did so multiple times. He was too fierce, simply beyond belief.
