Over the past few days of interacting with many mutants, Li Yuan discovered that Avril's sensory abilities complemented his own quite well.

Li Yuan could detect if someone was a mutant, and once they became his crew member, he could access their relevant information. However, he couldn't assess the strength of mutants who weren't under his command.

On the other hand, Avril couldn't obtain detailed data but could roughly gauge the opponent's strength.

Xiao Bei, Wu Zhan, Selena, and even the powerful figures behind the big guy Yuan Zun, she could vaguely sense their might.
