After Empress Nuwa, came the Human Ancestor and the Three Sovereigns and Five Emperors, as well as Jiang Chen's parents—that Innate Dao Sovereign-level Fierce Beast was prepared for them.
Jiang Chen's parents, in terms of status, were certainly not comparable to the Three Sovereigns and Five Emperors and the Human Ancestor.
However, they had a good son. As the saying goes, a child's fame reflects glory upon the parents. With Jiang Chen's extraordinary character, his parents would naturally bask in his glory, their status suddenly elevated.
Of course, the main reason was that Jiang Chen's parents were no longer alive; no one argues with the deceased.
Even if Jiang Chen forcefully elevated his parents' status to match that of the Three Sovereigns and Five Emperors, nobody would say anything. It would be a different matter if Jiang Chen's parents were still alive.
