Although Luo Yuan and the burly man before him had only made some simple probes during their fight, they were both powerhouses with abundant combat experience, so they could judge roughly what level their opponent's strength had reached from certain aspects.
First of all, there was undoubtedly a considerable gap between Luo Yuan's cultivation and the burly man's, but no particularly obvious difference in strength had emerged during their battle. This also showed that Luo Yuan possessed tremendous strength far beyond his current realm, although, on the surface, the fighting seemed less intense than before.
However, Luo Yuan discovered that every attack consumed far more energy than before if he was to block all the moves his opponent sent at him. From this, he could determine one thing: the opponent before him was far stronger than any of the geniuses he had fought previously.
After all, battles between powerhouses could not be judged by how their fighting looked. Instead, in every exchange, they could fully sense just how powerful their opponent's attacks were before resisting them in turn. Moreover, actual combat was what mattered in battle, and the most important thing was which moves were most practical.
If someone thought only of showing off during a battle and displayed flashy but impractical moves as a result, it would be meaningless. The super powerhouses watching could also instantly judge just what level the geniuses on the battlefield had reached.
For one thing, Luo Yuan had demonstrated formidable combat ability. He had not been suppressed by that Hunyuan Lord-level opponent at the outset, which clearly astonished everyone present. After all, the gap in strength was there, and making up for it was no easy matter.
Yet Luo Yuan had not fallen behind while fighting an opponent an entire major realm above him.
