Elara's eyes remained fixed on Zero, someone who she didn't recognize but was far more powerful than many of the geniuses including Hiro.
Looking at the appearance, Elara was able to make out that Zero was younger or was of similar age to Hiro. But Zero had completely outranked Hiro who she thought was the most talented.
Elara stared at Zero for a few more seconds before turning her head towards King Tranduil to ask about Zero.
However, when she turned her head, she noticed King Tranduil having a stunned expression with his eyes widened. And the direction he was looking at was Zero.
Despite huge expectation, even King Tranduil didn't expect that Zero would go from Rank-A to Rank-S -.
King Tranduil obviously wanted to know Zero's progress since he wanted to prove to Elara that Zero was also someone that they needed to keep their eyes on.
However, Zero's progress was far greater than what he thought which left him stunned.
