Although such an unexpected event occurred, the appearance of the fourth Ghost Immortal went unnoticed by the Hell specters.
After all, Bull Head was indeed a genuine Ghost Immortal, and no one could have imagined that someone had managed to smuggle themselves from Ying Island to the inside of Yomotsu Hirasaka in reverse.
Bull Head, under the guise of the Spirit Stalwart Ghost Immortal, infiltrated the ranks of the Hell specters and became one of the most revered among the four Ghost Immortals.
By transmitting messages through the invocation of Fengdu Emperor's name at heart, Shen Yuan quickly ascertained the reality of Yomotsu Hirasaka and came to a strategy of watchful observation with Bull Head.
From that moment on, every move of the supernatural beings within Yomotsu Hirasaka was under Shen Yuan's control.
During this process, Shen Yuan even returned to Great Xia to deter the major powers and subsequently took away the Emperor's Carriage from the Netherworld.
