Those eyes naturally belonged to Foolish Old Man and the others from the Supernova Alliance.
When Foolish Old Man had advanced to S-rank, he had used an extremely rare spatial relic, so he could wield the authority power of space.
He had thought that this top-tier authority power would be enough to catch them off guard and reap the spoils of their struggle.
He had never expected this "Zero" to be so terrifying, and for the moment, he dared not jump to conclusions.
Before he could decide whether to reveal himself, Lin Yuan's battle over there had already ended.
Just as Lin Yuan himself had previously concluded, his fighting style was completely different from that of normal S-ranks.
Normal S-rank battles were wars of attrition, unless one side possessed an overwhelmingly powerful weapon like the one Fei-ge had used against Prince.
Clashes between different authority powers often consisted of each side fighting their own fight.
Both sides exercised their unique abilities within their respective domains; neither could stop the other.
Thus, a battle between two evenly matched S-ranks generally lasted a very long time, giving either side plenty of opportunities to escape.
But Lin Yuan was different. His A-rank energy could nullify his opponent's authority power.
As long as his opponent's authority power was neither abundant nor strong enough, Lin Yuan could use his A-rank energy to suppress their every move and kill them on the spot.
Conversely, if his opponent's authority power was so formidable that Lin Yuan could not suppress it even after exhausting his A-rank energy, he would become the one at their mercy.
So if normal S-rank battles were wars of endurance, Lin Yuan's battles were life-or-death contests from the very first move.
Either you died, or I did.
There was no trading blows, escaping, or
