"S-rank?" Lin Feng had sensed from the Sword Qi just now that this old man known as Uncle Li was truly out of the ordinary—an S-rank expert! He truly hadn't expected to encounter such a high-level expert in Tianhai, a supercity in the Secular World.
Cheap old man had said before that AA-rank experts were already very rare in the secular realm, AAA-rank experts wouldn't move around unless there was something special, while S-rank experts were restricted by many things. Unless there was some major event, S-rank experts were strictly forbidden from entering the Secular World because their battles were simply too exaggerated—in the eyes of ordinary people, they were like human-shaped nuclear bombs.
