The "Brain Power Burst" show team took Zhao Yi's record attempt very seriously. Not only did they invite a judge from the Guinness China agency, but they also invited two notaries from the government.
In addition, there was also a witness from abroad.
Bertrand Kowalski from Poland, a professional Rubik's Cube blindfolded solver.
He ranked second in the world for single-blindfolded three-order cube solving, fourteenth in the world for single-blindfolded four-order cube solving, and twenty-first for single-blindfolded five-order cube solving.
At the same time, he holds the record for the most blindfolded solves completed in the world, successfully solving 41 three-order Rubik's cubes blindfolded in 54 minutes and 14 seconds.
Kovalchik was curious about Zhao Yi. He was invited to participate in the "Brain Power Burst" show, but didn't expect to come and witness a Rubik's cube blindfolded solving record attempt.
