Debt

Varian saw the tree slowly slipping into the ground as a golden light shone.

He stepped towards it and saw a spinning fruit bathed in the light.

"...this won't be poison, right?" He grabbed the apple-like fruit. 

The lightning mana in his body roared. 

It was like it was screaming at him.

'Devour. Devour. Devour.' 

So Varian devoured the fruit.

It was soft and cold. After entering his mouth, it melted and Varian could feel the smooth lightning mana boiling in his body. 

In response to the incoming lightning mana, the one within his body boiled and they slowly merged.

The System prompted. 

[+1Xp]

And stopped.

"Huh? Wtf?" Varian wanted to kill. 

It resumed and this time, it didn't stop for a while.

The lightning mana rose and lightning sense expanded continuously.
