2nd Class Spirit Energy

Cain and Kali's current position was locked in a dead stalemate. Their fists struggle against each other, neither willing to give even an inch. 

The sibling certainly heard Amber's complaints, but Kali didn't register it. Her battle-hungry smile threatened to split her face as she felt slight numbness within her fist. 

She clearly sensed it. Cain utilized the same amount of energy as her, yet she was the one that was clearly experiencing a slight loss.

Her arm just slightly quivered under this violent collision. Yet Cain remained tall and firm, almost like an unmovable wall. 

'Hmph. So what if you keep on improving? I won't lag behind at all!' With each rate of improvement, Kali felt her own self-confidence wildly surged. 

Of course, she's fully aware that Cain genuinely has her beat in terms of Martial Talent.

But with hard work and powerful improvements, the distance will be eventually crossed!
