When swordsmen fight, it isn't their cultivation base that determines who will win. It is their sword domains and sheer understanding of true swordmanship.
They fight using their understanding of the sword, which is mostly their sword energy (intent and aura) and their sword domain, which is a manifestation of their sword realms and concept.
If one's understanding is deep enough, they can easily win.
However, as Old Sword said, Kent is a genius, but against a sword domain, he can't really think he would win that easily.
Now, as he stood inside Old Sword's Immortal-level sword domain, he could feel the space around him start to reject his presence. The laws were being rewritten, and if he wasn't careful, he would be swallowed by a grave, resulting in his defeat.
"So this is your sword domain, huh? Not bad at all." Kent looked around, immediately grasping the nature of Old Sword's domain.
