Get to the Point
Tl:dr Dao ancestor Hong Yun is probably the first Chinese Mc archetype in all of history ,he is beyond overpowered and many mcs and final villains are based off of him . Old villainous heavens of ED , Patriarch Allheaven ,etc drew inspiration of him . 三清:of the three pure ones , Grand Pure One (xuandu and Changshou's master) is the strongest . This is due to cultivation nearing that of Hong Yun's ,but if he wants to surpass the world like Pangu , or what Hong Yun could've done back then ,he would have to face the heavens since this will subvert the world itself . His treasures are also top tier ,overall the #1 beneath/ equal to Hong Yun. This is followed by the Jade pure one and supreme pure one . Their cultivation is lower , but also with top tier treasures like the immortal execution swords and pangu banner (sounds familiar ? Myriad beast banner of other novels like plundering the heavens is based off of it . God execution knife/stage of THG and the beheading sword of plundering heavens is based off of the 4 immortal execution swords .) Next is Jie Yin who has equal cultivation to the Jade and supreme pure ones ,but lack of top tier treasures . Nuwa has lower cultivation than them all ,but her merit and treasures are overpowered . She did mend the pillar of heavens and create humanity ,heaven heavily favors her and this is her strength . Overall ,either she or Zhu Ti is the weakest however ,but Nuwa is very troublesome to antagonize due to her basically being the highest merit outside of the heavens itself . Zhu Ti presumably is the weakest of all the saints in regards to both treasure and cultivation . Xuandu used his chance of sainthood to refine his op treasure and if Nuwa wasn't so favored by heaven he could probably face her . Zhu Ti would be even easier .. The balance of power will shift in the future however ,especially with the whole Great God conferment ,Buddhism ,ascension and ones like Xuanzhang and Great sage equaling heavens falling to western sect
