Su Changxing smiled, put away his gun, and said, "Haha, just kidding, don't mind me. You know I'm stronger than you... Can you gauge my strength?"
The person looked puzzled and said, "It's a game, you know the definition of a game, right? Being able to see your levels is quite normal."
Is it normal?
It's like they naturally possess the talent of "True Knowledge."
"True Knowledge" isn't considered Su Changxing's ability, just his talent, something granted by the Doomsday Game, and was considerably weakened after his cranial death.
To enhance "True Knowledge," one would need to promote it into his ability, but the specification of "True Knowledge" is too high for him to upgrade it.
Su Changxing continued to ask, "Then what level am I?"
"Level 19 of Golden Quality." The person said casually.
"Golden Quality?"
