Mr. Liu was definitely an extraordinary individual.
He was a true explorer who had touched upon the 'spirit' realm, seldom entered by anyone in the Supernatural World. Perhaps he wasn't as aggressively decisive as Mr. Cao's slashing but Mr. Cao's blows could never land on Mr. Liu.
Luckily, Lin An had gained the 'spirit' augmentation, essentially one of the lucky successful experiments among the countless Mr. Liu had conducted on his path to exploring spirituality.
Ever since revealing himself to be the 'Black Cat' wizard, Lin An had been on guard against Mr. Liu.
Because he knew that Mr. Liu would definitely use the clue of the "Black Cat-Eyeball Witch Demon" to deduce the rich fruits his former experiment had borne.
He knew it, Mr. Liu would definitely take action against him.
And the countermeasure he prepared was to create the Root Spirituality version of Mr. Liu's 'Wizard's Will'.
