xie lian took 2 days to heal after his stab wound on beizi hill
he tooks several months to recover after the temple scene with white no-face
he took a year+ to heal after being trampled in banyue
the quick pace of healing after the temple scene makes me headcanon that he didn't give himself enough time to do it properly, meaning he was in a lot of physical as well as mental pain during the no-face arc.
