Zhao Fu looked at the black bull demon before him with some surprise. In merely three days, it had transformed from a wild beast into a demon. The speed was astonishing, and it had even gained a trace of decent intelligence.
Moreover, this black bull demon's strength had become immensely formidable. As a wild beast, the black bull's strength had only been comparable to that of someone at the second or third stage, but now it was equal to someone at the fifth or sixth stage.
