One of them was the skinny teenager, Huang Shang. His application of his incorporeal switching ability allowed him to easily clinch victories in the tournament.
The other was a bespectacled teenager who hadn't spoken very much while aboard the ship with the rest of them.
His name was Bai Heng, and his special ability was forcefield that allowed him to manipulation all forms of energy within a particular radius around him, although there were quantitative and qualitative limits to this function. As the top twenty was mostly dominated by 'Gifted' with energy-related abilities, Bai Heng's special ability worked to his advantage and proved extremely useful.
As for the others like Jiang Po and Liang Qiang, their performances were not as eye-catching as quite a number of other participants also displayed the same special abilities as them. Still, they clinched the top spots in their respective ability tiers.
