The black light on the chain is naturally the Devouring Power Yang Yan released in imitation of Demonic Qi.
Because the Devouring Power of Demonic Qi can devour various energies, Yang Yan had a sudden idea to try using this Devouring Power to absorb the soul of Manhattan.
Originally, he was just trying it out, never expecting it to succeed so effortlessly!
As Manhattan's soul was completely absorbed by the black light on the chain, Yang Yan felt a sense of exhilaration.
It wasn't just the thrill of having avenged his grievances; it was also closely tied to his absorption of Manhattan's soul.
Under a subtle sensation, the bottleneck that had not advanced for a long time surprisingly showed some slight loosening.
However, this progress had little to do with his own strength and reflected a level that even Yang Yan couldn't comprehend.
Though he couldn't understand the reason, he still had an inexplicable feeling that he had indeed made some progress in certain aspects.
