Makes sense but revealing it offscreen ruins the idea of 'telling the truth'. I understand why Niki offscreened it, but he should have done jump cuts to let us see Chao's reaction to individual revalations and give us an opportunity here and there to comment on his reaction. I dont think we've actually told the truth of the outside world and about cultivation to anyone so its disappointing that the first person we reveal about it to happens in offscreen. I understand offscreening it after we did it once since idea the of revealing a secret loses its meaning gradually.
