Derry had this Ulster Championship game wrapped up by half-time as they enjoyed a 13-point lead against Fermanagh.
Eoin Bradley's goal and a string of well-taken long-range scores had John Brennan's Oak Leafers seemingly out of sight and into the last four.
Division Four outfit Fermanagh did battle back and outscored their top flight opponents in the second half with John Woods getting their goal.
But Derry went through and will face Down or Armagh in the semi-finals.
Afterwards Derry boss Brennan was scathing about his side's second half showing.
Fermanagh made a bright start with Terry O'Flanagan converting a simple free after Tomas Corrigan had been fouled close in.
But Derry, who opted to play with the breeze in the first half, took over to completely dominate proceedings.
Nine different Oak Leaf players, including three defenders, scored before the break and all the scores came from play.
Gerard O'Kane's opening point levelled matters before Derry got their first-half goal.
A quick free found Bradley on the right and he turned marker Michael Jones before netting with a left-foot shot from a tight angle.
Mark Lynch, Sean Leo McGoldrick, Bradley (2), Conleth Gilligan and Enda Muldoon added points and Derry were 1-7 to 0-1 up inside the opening 15 minutes.
Centre half-back Charlie Kielt advanced to score, Joe Diver got in on the act and O'Kane got his second.
Then corner-back Michael Bateson made his way up to land a point before Gilligan registered again.
Fermanagh's only other point of the first half came from Daniel Kille.
It did not get any better for Fermanagh at the start of the second period as Derry's Muldoon, Diver, Bradley and Lynch reeled off scores.
Kille then landed a free before corner-back Woods advanced to net a superb right-footed strike.
Ryan Jones (2), Kille (3), Chris O'Brien and Barry Mulrone got points to lessen the one-sided look of the scoreline.
Gilligan and Bateson got Derry's other second-half points.
