Because as long as they are below the "True and False Changes", they cannot resist the occurrence of the concept of "Turning the True to False".
However, transforming a complete thing from real to fake corresponds to transforming an illusory thing into real. And its existence will not disappear with the disappearance of the power of true and false.
This Great Achievement Realm is naturally not something the just-beginning Li Fan can achieve.
"Mostly because the true state of things can be maintained for a certain time. Once it falls into a false state, there's no chance to revert to true again."
"Once it disappears, it's gone forever."
The reason he suddenly thought of this key point was because Li Fan observed that the process of the Transcendent Mystic Coffin "disappearing" from the current possibility was not completed in an instant.
