After conceding 12 tries without even managing to kick for goal successfully, the Broncos now hold the unenviable record of having suffered the worst-ever defeat at this level.
The thrashing means London have now conceded 182 points in three matches against the Warriors this year.
While it was a horrible night for London, Wigan had plenty to celebrate.
The monster win sealed the Warriors' 30th Challenge Cup final appearance, saw winger Josh Charnley score his 100th try for the club, and boasted a 30-point haul for Pat Richards, who will return to Australia at the end of the year.
The Warriors had 10 different try scorers as they broke their own record for the biggest margin of semi-final victory, eclipsing their 71-10 win in that match against Bradford 21 years ago.
The try feast was lapped up by the Wigan fans who made up the bulk of the 6,274 crowd at Leigh Sports Village but as a contest this was a non-event which did little to enhance the credibility of the game.
