However, Qin Feng only intended to teach the chubby security guard a lesson, so he didn't use any internal energy, just a bit of surface skill.
But even being merely surface skill, Qin Feng's fist was still harder than steel!
When the chubby guard's fleshy knuckles collided with Qin Feng's fist, it was as if he had struck an iron lump.
"Thud!"
Accompanied by a muffled sound, the chubby guard felt his fist numb, as if his hand was no longer his own.
Then, a sharp pain transmitted from his hand; his fingers were actually fractured on impact.
"Ah! Ahh!"
The chubby security guard held his fractured hand and wailed miserably.
Although the chubby security guard missed, the lean guard's electric baton, instead of stopping, accelerated and increased force, aiming directly between Qin Feng's legs.
Between the legs is the most vulnerable part of a man, and the electric baton in the lean guard's hand was a high-voltage one, the dial turned to its maximum setting.
