He could be certain that Mu Hanyan hadn't hidden her strength at the time, which meant her power had really soared from a sixth-tier Swordsman to Tenth Rank in less than half a year.
Could it be due to the Life-bound Star Disk left by ancestor Tian Lie? Apart from this, Mu Feng couldn't think of any other possibilities. In fact, he wasn't completely wrong; the Life-bound Star Disk indeed played an indispensable role in Mu Hanyan's strength today. However, what he didn't know, was that not just anyone could benefit from Mu Tianlie's Life-bound Star Disk—if it had been him, not to mention a surge in strength, even his life would have been at risk.
Mu Feng's feelings were conflicted. The Life-bound Star Disk left by Mu Tianlie wasn't exclusively for his direct lineage; it only showed slight favoritism towards his own children. Any descendants of the Mu Family could own the Life-bound Star Disk if they were fortunate enough, so Mu Hanyan owed them no gratitude.
