At the same time, the Tian Yuan continent had a very prominent profession called the Mercenary. According to this book, the Tian Yuan continent had many mercenaries. These mercenaries would accomplish a variety of tasks for money, although many mercenaries would enter the Mountain Range of Magical Beasts to hunt monsters and sell the monster cores for money.
Although the dangers were big, the rewards were just as generous due to monster cores being highly valued in the continent. The higher grade a monster core was, the higher priced it was. There were some high ranked monster cores that could not be bought with money alone.
Monster cores were one of the most desired items in the continent. Inside the center of a monster core was a large amount of pure energy and could be absorbed by humans for a faster training speed. Absorbing the energy from a monster core was ultimately faster than trying to absorb the World Essence into one’s body. However, using the monster cores to increase the cultivation speed wasn’t a method the general populace could do without having plenty of money.
