For nine full days and nights, Ren Jie stood there without moving, yet he continuously pushed the Nine Nine Yin Yang Suppressing God Banner to its limit. Combined with his own power, he drove his Divine Soul Power to the utmost as well. If he had sufficient Immortal Qi, Immortal Spiritual Energy, Sea God Spiritual Energy, or something similar right now, Ren Jie would probably have long since drawn upon the Sage Dao Discussion Realm.

Ren Jie had already studied Mad Bull's body. It was not his true body, but unlike Qi Tian, it had been recondensed upon the foundation of his original body. It differed from Qi Tian's incarnation, making this body even more formidable. It should have far surpassed ordinary immortals, since Tian Zhu and the others could only injure him by driving Immortal Artifacts to their limits.
