Lighten Evolutionary Body Tempering Technique

"Huff... Huff..." A young man covered in mud could be seen running through a dense forest with black trees.

His clothes were in tatters, and numerous wounds could be seen on his body.

The young man was Lux; he was currently running. From something...

A few tens of meters behind him, trees were constantly falling as a five-meter hound was accelerating towards him.

Black scales and red eyes resembling blood, the hound spewed flames left and right as it tried to catch up to Lux.

After talking with Dark Master— Maxwell, the man proposed to Lux a deal.

The deal was pretty simple; he would provide enough Demi-Gods for Lux to kill, without caring about their lives at all. Lux needed to hunt them without using his Light God Ability.

This was because Maxwell wanted Lux to rely only on his physique to kill the dark beasts.

The reason?

Training.
