All that is what people know about him yet in actual fact, he did have a special constitution, the first of it's kind , the nine tribulation body.
In every major realm, he faces nine tribulations, be it in form of karma , lightning tribulation , schemes and even betrayal.
To him this wasn't a gift from the heavens but a form of suppression by the heavens as the plots became harder to unravel and the lightning tribulation became even more ridiculous. Imagine a brat breaking through golden core realm facing a void shattering realm and don't get me started on the immortal realms , instead of every major realm , every minor realm he'd received a tribulation worse than the last and this only stopped when he broke through the barrier that had stopped many mortals through the years as every nine years he faced schemes by the very heavens but having reached such heights, the heavens had little they could do to obstruct to obstruct his path, all they could do was play simple schemes that could only slow down his his growth in power. This was the reason that he hadn't fully united the heavenly realm as these natives of the upper world still had that persistent pride, it's about time that they were put in their place.
Having made a truce with the celestial emperor and the focus of the heavenly dao on the the black tower as though it figured out the source of our feeling of danger.
As the elves were the defacto leader of said faction, the events that happened next didn't, could not be uttered for the shame of their defeat was so great that and so final that any thought of rebellion were crushed thoroughly even .
And all this happened with in a single week ,with the immortal emperor taking the lead and his brother the battle god BaiZhang.
No immortal emperors were killed in the conflict yet all the immortal emperors had their souls damaged just enough to meet the 1500years, apart from a few broken legs and ribs just to get the point across, nothing else major was done to them as at that point many had been driven to the brink of insanity.
The matter took a weird turn when news of the great war god having an unclear relationship with the sister of the elf matriarch reached the ears of the individuals he'd paid a visit to understanding the reason for the immortal emperor's mercy,after all who didn't know of the emperor's love for his brother and the deep loyalty of the war god.
What truly interested them was the new concept of weapon the emperor had introduced.
A fate weapon he called it, born from his dao , blood ,soul and will.
Nothing seemed to stand up to it and it was at that moment that the monstrosity called Bai zhanlong was trulyseen , for it was finally exposed that the sovereign dao, one of the most overpowered daos to exist was simply one of the nine daos that formed the nine tribulations dao.
