Judd Trump's quest to hold all three Triple Crown titles remains on course after a 6-1 win over Mei Xiwen in the UK Championship.
Trump, 30, claimed his maiden world title at Sheffield's Crucible Theatre in May, having won the Masters in January.
The world number one made frame-winning runs of 105, 93, 86, 68 and 51, while Mei managed a superb 127 clearance.
"I did not feel great out there. I struggled a bit today," Trump said.
"When I won the World Championship, it was a massive weight lifting off my shoulders.
"To win the Masters and World Championship together gave me the mental strength to go out and stamp my authority on the sport.
"It's taken to the age of 29 to dedicate myself to the sport and really push on for the next 10 or 15 years or however long I can play to the best of my ability."
Two-time champion Ding Junhui beat Michael Georgiou 6-2 to progress to the third round.
The Chinese player, who lifted the trophy in 2005 and 2009, has endured a difficult season with three first-round defeats but compiled breaks of 100, 70 and 50 on his way through to the next round.
Three-time UK champion John Higgins made light work of China's Lu Ning with a 6-1 victory.
World number 62 Michael White caused an upset by beating fellow Welshman Mark Williams 6-2.
Three-time world champion Williams made a break of 102 but was rather off-key, as White made breaks of 65, 75, 52, 81 and 64.
Former UK finalist Liang Wenbo defeated David Grace 6-3 in his second-round match, just days after the death of his mother in China.
Liang flew back to his homeland following his first-round win over Dominic Dale on Tuesday to help with the funeral arrangements before returning to Britain this weekend.
Trump aiming for rare feat
If Trump and Ronnie O'Sullivan remain unbeaten they will meet in next Sunday's final.
The pair met in the final of last month's Northern Ireland Open, with Trump winning to secure the 14th ranking title of his career.
The tour's form player has won two other ranking titles this season, although he was beaten in the invitational Champions of Champions event.
Renowned for his cue power, some of Trump's potting against China's Mei was outrageous, including powering a brown into the middle pocket and screwing back off the baulk cushion for the cue ball to roll down the table.
He realised his potential by winning the world title last season and is now aiming to achieve a feat managed by only three other players and hold all three blue riband crowns at the same time.
Stephen Hendry won all three in 1996, although that was over two seasons, while Mark Williams was the last to win all three in the same season in 2002-03.
Steve Davis is the only other player to have managed the feat - despite winning the most Triple Crown titles overall with 19, O'Sullivan has never held all three at the same time.
Trump said: "After I started the season well, it has been something I have looked at and a lot of people have mentioned it. It is such a rare feat and would be unbelievable.
"Hendry last did it over 20 years ago so it just goes to show how hard it is to do. If I can get achievements in that bracket then at the end of my career I can be mentioned alongside the likes of them.
"It does not come around too often and this chance may never happen again. Ronnie has never done it so it shows how tough it is.
"You have to play your absolute best in these big events and it is something I have worked towards. Hopefully I have have the confidence and mental strength to do it."
Trump will be confident of his chances in the next round, against either tour rookie Louis Heathcote or 54-year-old Nigel Bond.
