Squeezing out potential and forcing a breakthrough will cause one's foundation to shatter. Once the foundation is shattered, if it is not repaired, it may lead to a regression in cultivation—that is still the small problem. The big problem is that one will never again be able to break through to a higher realm for the rest of their life.

At this moment, however, the Extreme Venerable revealed a trace of frenzied smile: "Do you really not know? The secret of the Son of Destruction—if one obtains the secret of the Destruction Form, then what counts as squeezing potential and forcing a breakthrough?"
