Fang Mu discovered that the higher the spiritual intelligence of a being, the stronger its attachment to him after being bound by Covenant Blood Essence.
Among all the Guardian Beasts contracted by Fang Mu, Liu Xi was the one most attached to Fang Mu.
Liu Xi stood nervously in front of Fang Mu.
Liu Xi knew that Fang Mu was preparing to use a large amount of resources to cultivate him, with the purpose of controlling Mister Hei.
Liu Xi had already experienced the quality of Mister Hei's soul and had a clear understanding of it.
This allowed Liu Xi to determine, without experimentation, whether he could control Mister Hei.
Stepping into order, the greatest enhancement was to the soul.
Liu Xi was not sure if he could meet Fang Mu's expectations.
Liu Xi was afraid that even after absorbing those Evil Spirits, he still would not be able to control Mister Hei, disappointing Fang Mu.
Normally, those Evil Spirits would not all be used by Fang Mu to cultivate him.
