Soul Slayer was slightly taken aback, not knowing what Wu Jiu was going to say. The situation before its eyes had truly far exceeded anything it could have expected. It had never thought that Wu Jiu would really be so audacious to dare to put the Beast Spirit's Spiritual Bear in captivity!
"Why?"
Wu Jiu suddenly laughed out loud. He stared at the Spiritual Bear viciously and he spat out through gritted teeth: "Because the construction of every Serene Spirit Tower requires a sufficiently powerful spirit body as its support, and the supporting spirit for the fourth Serene Spirit Tower is the Spiritual Bear!"
"What! ?" Soul Slayer was completely stunned.
