Debutant Lei Peifan stunned defending champion Kyren Wilson by fighting back from 6-2 down to triumph 10-9 as the 'Crucible curse' struck again.
Wilson becomes the 20th player to succumb to the so-called curse, with no first-time winner able to retain the world crown since the tournament moved to Sheffield's Crucible Theatre in 1977.
"It is really hard to take. I gave it my all and Lei came out extremely positive this evening and potted some incredible balls," Wilson told BBC Sport.
"It really hurts to be honest. As a debutant he held himself together incredibly well and I'd like to wish him all the best for the rest of the tournament.
"He seems like quite a cool character. He showed no emotion at all."
Joe Johnson (1987) and Ken Doherty (1998) came the closest to breaking the 'curse' but fell at the final hurdle.
Wilson added: "It's obviously been built up into something it's not, because other players have gone on to win it. I'm sure it'll be broken at some point but unfortunately I won't be that person."
