So that's who the white hair senior was. It got me confused since last ep since he was never introduced properly, but just suddenly took over Tantai Xuan Zhong's position when he left.

I couldn't have guessed that was Tan Yun. Man, that got me by surprise. The disguise was impeccable.

Sect master will be shocked and leave his mouth wide open as usual when he see MC

im pretty sure they told the sect master he wasnt really dead.

Yeah, but he explained that the tablet wouldn't be of any use once the portal closed, hence why Meng Yi fainted/fell over

yes they did
