As the Contractor of the Heavenly Disaster Level Ghost Series Summoning Beast, Fang Mu was well aware of the reason why, despite the formidable strength of such beasts, few people chose to contract with them.
He was very clear about how many resources had been poured into Yan Yubanruo.
This summoning beast of the Ghost Series derived most of its skills and unique traits from the summoned creatures it controlled.
The more summoned creatures there were, and the stronger they were, the more formidable Yan Yubanruo became.
If Fang Mu had only equipped Yan Yubanruo with two or three summoned creatures, it simply would not have been able to defeat other Heaven Calamity Ghost Series Beasts of the same class.
To nurture an Undead Creature required an investment of resources that was in no means inferior to that needed for a living Guardian Beast.
Especially since it required a large number of Soul of Deaths.
