Spoiler from the novel
I dunno if they will still keep the fact SYS was the Imperial Emperor Yuanyang in celestial and because he have something happen in heaven, did have the tribulation with Mu Qingge. They know each other in heaven...She was the daugther from the Holy Mother and Celestial Sovereign. The crime was Imperial Emperor Yuanyang and her was...
The holy mother nutured her under the bodhi tree for a thousand year and was her only daughther and Yuanyang came and was drunk, he picked the fruit which wasn't matured yet...that was a crime (the true is she want to protect him from a snake so she falling herself in his hand)
Wei Jiu was the best buddy with SYS later, his daugther and SYS son...will be surely together later lol
