Adam Peaty is targeting two more World Championships gold medals in Budapest on Wednesday, after surprising even himself on Tuesday.
Peaty twice bettered his own 50m breaststroke world record on day three with his daily improvement 0.47s, as he qualified for Wednesday night's final in 25.95s.
The Olympic 100m champion won world gold over two lengths on Monday and is also expected to come into the Great Britain team for the 4x100m mixed medley relay, assuming the defending champions qualify from the morning heats.
Peaty, who won Britain's first gold medal of the Rio Olympics, is in fine form and proved it again on Tuesday.
The 22-year-old's own 50m world record of 26.42s had stood since his victory at the 2015 World Championships in Kazan.
He clocked 26.10 in the morning heat and then went 0.15 quicker in the semi-final, taking himself 0.73 clear of the field.
"I didn't think I was going to do that," said Peaty, who shook his head in disbelief after seeing his time.
"Obviously it's nothing without the gold that goes along with it.
"I'm going to be focusing now, staying neutral and see what we get [on Wednesday]."
Asked if he had more to give, Peaty said: "Oh yes, 100 per cent."
Peaty's advantage is a huge margin over two lengths of the pool, and, having learned from experience since 2014 and winning Commonwealth, European, world and Olympic titles, he is focused on himself.
"I thought I was going to go slower [in the semi-final] because I was a little bit less energetic," he added.
"But [Wednesday's] the day to do it, really. We'll see what we get."
