Headless can be stuck, the underworld is clear, and then you turn around with headless. As long as he puts out the skill of taking pictures, you can cut him, and he will stand still. At this time, you have to move a little above him (that is, stagger Y XXXX), and then you can stand in the original place indefinitely. Remember, you can get stuck anywhere, as long as you put that skill headless and you don't need any special coordinates to get stuck.
If not, watch more videos of headless brushes, which is very helpful to you.
