how do i unlock the underground ruins?
i've done Cartethiya's Sonic slide challenge, but the ruins on the opposite side are locked and i can't find anything to do about it

Tower and MoC both reset today. MoC was a pain in the ass with a shill buff for a character that isn't even out yet. Thanks WuWa for making right tower fire weak and center tower fire/wind weak. I needed a stress free tower clear after dealing with Hoyo's nonsense

>except fusion-res bosses.

Soon not even that will stop him. I may try to commission some art of Changli, Brant, and Lupa all together once I get the whole squad together
