It was natural for failures to occur in cultivation.
As for Shen Baifei, his early years of numerous conflicts had resulted in many hidden injuries, compromising his physical condition.
His age, declining vitality, mental state, and the strength of his spiritual energy made it difficult for him to reach the peak state required for a successful breakthrough.
Even with life-extending elixirs, it was hard to compensate for certain deficiencies.
Of course.
The most important factor, however, was the lack of opportunity.
It's worth noting that Shen Yuanlong was in an even worse state than him back then.
However, in the end, he succeeded in forming the core.
What did this mean?
This demonstrated that Shen Yuanyong's fortune and opportunities far surpassed Shen Baifei's, compensating for his shortcomings.
The elusive nature of fate and opportunity made it impossible to predict outcomes until the very last step.
