Bai Pu becoming a standing member of the council sounds somewhat startling, but to put it bluntly, the reason is quite simple.
The biggest reason is that Bai Pu is extremely formidable in combat.
Having only been awakened for a year, he can go toe-to-toe with the Dragon King (as described by Xiang Yinghua himself), which shows his immediate combat prowess, not just potential.
Being able to fight with the Titled Strong Person, Dragon King, and escape unscathed indicates that Bai Pu at least possesses the strength of a "title contender," akin to that of the Dai Sect level.
In Huaxia, the five pinnacle titles in combat are Dragon King, Power King, Sword Saint, Celestial Being, and Divine Throne.
Each pinnacle title has one bona fide titled strong person, plus five to ten "contenders."
These are the peak Awakened of all Huaxia, just a few dozen people. Of course, this doesn't rule out some hidden masters with sufficient strength who do not participate for various reasons.
