First, judging by the timeline in the original novel, Bibi Dong gave birth to Qian Renxue the same year she broke up with Yu Xiaogang.
Then Yu Xiaogang went traveling and met Flender and Liu Erlong. They spent several more years establishing the Golden Iron Triangle's reputation, before parting ways for certain reasons. Afterward, Flender founded Shrek Academy.
Even taking a conservative estimate of two years, Shrek Academy was officially established when Qian Renxue was two.
Next, at the time Tang San enrolled at age twelve, Qian Renxue would have been twenty or twenty-one, since she was eight or nine years older than him.
That meant Shrek Academy had existed for eighteen or nineteen years at most.
Add to that Shrek Academy's rule against accepting students over thirteen, and the Shrek graduate who had become an elder of Spirit Hall should still have been under thirty-two.
Yet aside from Ning Fengzhi and Yu Xiaogang, every elder of Spirit Hall was a Titled Douluo above level ninety-one.
Although Ning Fengzhi was only a Soul Saint, the Seven Treasure Glazed Tile Pagoda's support abilities were powerful enough to defy heaven. His strategic value surpassed even that of an ordinary Titled Douluo.
As for Yu Xiaogang, those who knew, knew.
Finally, in the original novel, Dai Mubai had said this person's authority was second only to Pope Bibi Dong's. In other words, they were Spirit Hall's third- or fourth-in-command.
If they were third- or fourth-in-command, then let us give them level 97 cultivation. Otherwise, Golden Crocodile Douluo, the level 98 Super Douluo who actually ranked third in Spirit Hall, would have something to say about it.
Putting all those conditions together, if Dai Mubai had been telling the truth, Shrek Academy had produced a Super Douluo under thirty-two with cultivation at level 97
