Actually, Luo Qingfeng, Liu Mansha, Chen Nanfeng, and the others were all older than Li Yifu.
Therefore, the Golden core stage would act as a crucial watershed. If Yifu could break through the shackles of the Golden core stage, combined with Xia Ruofei's assistance, his future path of cultivation held great promise. However, if he delayed this breakthrough, his bodily functions would inevitably age, making it increasingly difficult to advance later on.
Ruofei deliberately spoke those words to instill a sense of urgency in Yifu, hoping the older man would shatter the Golden core stage bottleneck in one vigorous push. After all, transitioning from the Qi refining stage to the Golden core stage was notoriously difficult. Countless cultivators remained stuck at this exact hurdle for decades without making a single inch of progress.
