Watching the scene unfold in the sky, Lu Yang smiled faintly.
Having reached Ninth Grade Supreme and gradually touched the threshold of the Divine Path, Lu Yang was beginning to see clearly things that had once been beyond his sight.
The Heavenly Demon Altar, for instance.
Back at East Mountain Lake, Lu Yang had always wondered about one thing.
During the catastrophe ten thousand years ago, the Celestial Emperor Ji Tianjun, though only a demigod, had completely destroyed eight of the nine Heavenly Demon Altars. Why, then, had he left the last one intact?
Was it really because the Heavenly Demon had descended, leaving him no time to deal with anything else?
At the time, Lu Yang hadn't thought there was anything wrong with that explanation. But after becoming a Ninth Realm Supreme, when he looked back on it, he realized it made no sense at all.
The Spiritual Sense of an Eight Realm Venerable could cover an area roughly a hundred thousand li across.
The Spiritual Sense of a Ninth Realm Supreme could cover an entire continent, even stretching beyond it to encompass the vast seas surrounding it.
Ji Tianjun had attained demigodhood back then, and had even kindled a spark of Divine Fire.
Even from within the Heavenly Abyss, if he had wanted to destroy that altar before he died, there was no way it would have survived.
That damaged Heavenly Demon Altar, patched up yet still usable, seemed at first glance to be a rare oversight by the human Celestial Emperor. But it was far more likely that Ji Tianjun had deliberately left it as a back door, to "invite the enemy into the trap"!
Lu Yang guessed this back door had been meant for the Heavenly Demon that had been spying on the Nine Provinces World
