Killing two birds with one stone

'Ding,

 Master's tamed beast successfully killed a fire ghoul.

 Gained 0.05 percent of pure internal fire energy and the remaining 0.05 percent to the master's tamed beast.

Henrick was really surprised at the system notifications because he didn't think he would get free internal fire energy even when his tamed beast kills the fire ghoul.

'Even though it is only 0.05 percent of the pure internal fire energy, it is still pure internal fire energy, right?' Henrick didn't mind the low amount of pure internal fire energy because basically, he was getting it without doing anything.

'If I get half of the pure internal fire energy every time my tamed beast kills other beasts, then if I have other tamed beasts, then I don't need to endure the pain to fill my dantian with the pure internal fire energy, right?'

Soon, Henrick wanted to form a contract with other beasts. So that he could get the free internal fire energy.
