There are only two reasons for not being able to discern someone's cultivation level. Firstly, the opponent's cultivation level is far superior to theirs; secondly, the opponent has practiced some secret technique that can conceal their Martial Arts Cultivation.
But no matter what cultivation level the opponent possesses, or whether they've practiced some secret technique to deliberately hide it, that palm strike just now that killed all the Tuoba Family's strongmen has already made the experts of various families tremble.
It is known that the leading expert of the Tuoba Family was at the Peak of the Earth Level Realm. To kill him, one's cultivation must at least be above the Earth Level Realm Peak. What does this mean? Anyone who isn't foolish can understand.
At this moment, many eyes are focused on the body of Old Liu. The battle just now was absolutely shocking to these Ancient Martial Clans since Old Liu casually crushed a Peak Earth Level Realm expert.
