What is a secret skill?
If you think about how OP Ye Weiming's "How in Dai" and how tricky "Silent Dragon's No Use" are, you'll get it.
It's definitely a game-changer if you use it well, even allowing for major fights above your own level!
But of the two that Ye Weiming has learned, one is as frustrating as five years of high school entrance exam simulations, the other is only one-eighteenth of its original form.
However, what the Knife Girl got was a whole set of secret skills!
Does this mean that the game might produce another powerful player like Ye Weiming?
The answer is... certainly not!
If that secretive player really had strength comparable to Ye Weiming, he wouldn't have been killed by Knife Girl so easily.
From her casual tone, you could tell that the Knife Girl didn't even break a sweat killing him. At least, she didn't have to fight a tough battle.
