Holders Manchester City turned on the style with six second-half goals against Leicester City to seal an FA Cup semi-final meeting with Chelsea.
After a dull opening, Khadija Shaw's strike unleashed Gareth Taylor's side and they ran riot.
Vicky Losada doubled the lead before Shaw notched a second and Alex Greenwood netted from the penalty spot.
Shaw completed her hat-trick and Filippa Angeldahl rounded off the scoring in the final minutes.
After a 5-0 thrashing at Arsenal on Sunday in the WSL, Taylor said his injury-hit side are 'suffering' and he was only able to name four substitutes for this game.
Fatigue was evident in a lacklustre first half, but as soon as Shaw opened the scoring in the 47th minute, they came alive.
Losada smashed home a brilliant second before Shaw profited from a lucky deflection to make it three.
Greenwood dispatched a confident penalty after Lauren Hemp was fouled and there was still time for Shaw to complete her treble and Angeldahl to sweep home a sixth.
City have won the FA Cup in each of the last two seasons and, on this evidence, look well set to challenge again despite being handed a tough draw against WSL champions Chelsea.
