Can someone explain to me the last ep, the one in "50 years later", because I was confused if it was his dream because when he put on the VR thingy, he suddenly went to the obsidian house and then everyone and Lanzhu were there. I was a little confused if it was his dream or if he did programming (game) about it so that everyone could go back to where Qianli and the others still knew him. please answer this I'm actually overthinking this the whole time to the point that I can't sleep TT
