!! Warning: This hanjie is a linea, it is only logical with the constraint that the picture consists of a single curved line, thus each black cell has exactly two of its four nearby cell blacks (except the two ends) !!
Do you want any hint?
Difficulty : ***
Tested, logical (as a linea).
Edge-logic can be useful. Using connexity can make the resolution easier.
Good blackenage.
On ne peut pas dire que ce soit un linea loupé...
Bravo!!
