Disappear for a While and the artist is Dai Dai Yao
This is an illustration "artbook" that's 24 metres long!
Title of the book is Disappear for a While (须臾之隐) and the artist is Dai Dai Yao (呆呆药).
The scroll even comes with a cylindrical piece of wood to help you unroll and roll the scroll.
The art is long continuous piece that flows on and on. There are certain sections with some clever bits of drawing that keeps the transition smooth even though the scenes don't look like they flow.
