As the figure disappears around the corner, Kovalchik couldn't help feeling deep respect. He firmly believed that Zhao Yi was not boasting.
The Rubik's cube blindfold challenge is indeed tough.
Unless one is very familiar with the Rubik's cube and undergoes extensive training, it will be impossible to complete the blindfold challenge.
Zhao Yi is different.
As a professional Rubik's cube player himself, Kovalchik could tell instantly that Zhao Yi was not a professional, at most, an amateur player. The fact that he could complete a blindfold challenge was due solely to his remarkable intelligence and mental stamina.
Kovalchik had met people like Zhao Yi before.
If one argues that breaking a world record by manipulating a Rubik's cube solely with brain power can be seen as a joke.
