Heng Sao Tian Ya
So that means Kong shi was also stripped of his bloodline in order to save some dying Ancient Sage. That was why he laughed so hard when he knew that Zhang shi had it too. And said "it seems i am not alone anymore" implying that now there's another human being without bloodline. What a sad life. Im surprised Kong shi didnt become resentful towards the world.
I hope he doesn't immediately forgive them and treat them like family. I mean I don't expect him to hate them for it but I also don't think they're really qualified to be acknowledged as his parents after that. Based on their action of trying to put him in charge of the clan immediately they clearly don't expect him to treat them with any kind of deference which is good. Plus he's not exactly the original kid that they lost. All things considered I think he should see them as allies at best rather than close family.
So he is born connate saint with all the statues looking up to him, including Kong shi, yet they still chose to sacrifice him for that? seems legit. With all the fanfare at birth, wouldn't it seem like he could bring humanity to a new level again, heralding a celestial master teach, yet they still chose to sacrifice him...
