Lu Yaosheng himself was a martial artist at the Half-step King Realm, but the aura exploding from Liu Hanwen was definitely that of the King Realm.
The Lu Family was not without its King Realm Strongs, but none were so young.
Not just the Lu Family, but other families of the Nine Gates of Yandu also had King Realm Strongs, none as young as Liu Hanwen.
Under normal circumstances, King Realm Strongs of the Nine Gates of Yandu wouldn't easily make a move, nor show themselves readily, basically all of them were in seclusion, or even in deep slumber using the Turtle Breath Technique.
Because their lifespans were nearing an end, once they made a move, they were very likely to perish, so unless it was a life-or-death moment for the family, they wouldn't act rashly.
In such a circumstance, the Liu Family had actually produced a King Realm Strong who was just over fifty years old, one could imagine the sensation this news would cause once it got out.
