Actually, they weren't that intimidated by Han Lie's background.
The old men's power is something the kids can only make limited use of; you can't pull off any big, flashy moves with it.
Stuff that you have and I also have is at best a safety net, used to control the scope and intensity of conflicts; it can't really be used as a weapon.
That's how it is for them, and it's the same for Han Lie.
If every time kids get into a fight, the parents jump in at the slightest disagreement, how the hell is that kind of person supposed to climb to the top?
There are countless kinds of conflicts in the circle, and you're basically expected to handle them yourself.
So Square Face and the others didn't really fear Han Lie because of this; they were more shocked at how much Han Lie could endure and how good he was at hiding things, while also feeling a bit indignant, thinking Han Lie simply didn't take them seriously.
"That fucking guy…"
