Kento,
It turned from him having his powers from the difference in gravity on earth than krypton into him having the mental ability to manifest his powers because the yellow sun is now a source of energy for him.
His body transforms the sun's rays into biomatrix energy giving him powers.
He thinks hard and manifests these powers therefore he can lift the seemingly unliftable, jump the unjumpable, reach the unreachable, fly,heat vision, and etc.
