Killing a late stage Core Formation Tier

Ling Han crossed his arms behind his back, calm and unhurried, extremely pretentious.

Feng Kun was furious.

He was at the late stage of Core Formation Tier, and his battle prowess could reach the Sixth Heaven. To Ling Han, his battle prowess was one-sided, and Ling Han actually dared to pretend to be unfathomable in front of him?

As expected, he had given up on himself.

Feng Kun sneered, and with a flash, he raised his hand to deliver a palm strike at Ling Han's head.

Ling Han clenched his hand into a fist, and greeted Feng Kun's attack.

"You really overestimate yourself!" Feng Kun sneered.

Peng!

The two of them exchanged a blow, and a deep power surged out. Ling Han was sent flying.

Meanwhile, Feng Kun's expression changed drastically, because his brat's power had f*cking increased further, reaching the Third Heaven of Core Formation Tier.

What kind of concept was this?
