From the experience of another Supreme Heavenly Demon, Lu Yongnian, no great battle involving Supreme Heavenly Demons was found.
He died from a misstep in cultivation.
However, Lu Yongnian was not the Supreme Heavenly Demon from thirty thousand years ago.
Thinking about this, he shook his head, his gaze continuing to fall on the Black Box.
This Black Box is quite mysterious, especially its patterns, which vaguely resemble the Divine Language.
But it is not the Divine Language.
It is very likely a pattern derived from the Divine Language.
He sealed with both palms.
In an instant, a sheet of clear light appeared in the Void, suddenly falling like a bowl, covering the Black Box.
The light inside the Black Box flashed, attempting to burst out, but was jolted back as if electrified, retreating swiftly back into the Black Box.
Chu Zhiyuan smiled and continued to catalyze the Great Demon Suppressing Seal to refine.
The clear light grew thicker, increasingly bright.
