The physical body of a Peak Nascent Soul Realm expert is extremely powerful, and it is very difficult for those of a lower realm to injure them unless they use a Heaven Tier weapon.
Hearing this, Jiang Feng was momentarily stunned. Could the Frost Sword have been upgraded to the Heaven Tier by the Old Sword Spirit?
"What are you daydreaming about?" The weak voice of the Old Sword Spirit echoed in Jiang Feng's mind. "I can only help you raise your sword to the upper Earth Tier at best. To advance to the Heaven Tier, it must be recast by an advanced weapons smith. The reason you were able to injure him is thanks to that young lady; without her Formation, your sword truly wouldn't have been able to hurt him."
