The dark greenish-black-skinned giant was naturally Old Ox, whom Su Che had encountered back on Mystic Mountain.
Back then, Zhang San and Old Ox had obeyed Su Che's orders to investigate Guobei County, only to stumble into the Buddhist School's grand undertaking of using the Yin-Yang Realm to construct the Hungry Ghost Path.
Fortunately, Old Ox possessed a deep and solid foundation of cultivation, and his techniques also bore some connection to the Buddhist School. Only then had he managed to protect Zhang San and fight their way out of the Hungry Ghost Path.
After leaving the Hungry Ghost Path, the man and demon encountered Ghost Marshal Situ Tu, who was leading a host of Ghost Soldiers out of the Yin-Yang Realm at nearly the same time.
Facing a Reverted Elixir-level Ghost Cultivator—not to mention the Ghost Soldiers under his command—Old Ox had immediately dropped to his knees and pledged allegiance, abandoning all dignity as he submitted to the Ghost Marshal.
Zhang San had no choice either and could only follow Old Ox into the Ghost Marshal's ranks.
Before long, Old Ox had become quite familiar with the Ghost Marshal's side. Zhang San had preserved his life, and his status rose along with Old Ox's, like a boat lifted by the tide.
Zhang San had only wanted to find an opportunity to slip away and report the truth of the matter to Lord Su.
But Old Ox stopped him every time.
According to Brother Ox, they had originally been sent by Su Che to Guobei County to probe its depths. Now they had learned nothing at all, which meant they had accomplished nothing. How could they return to face their lord like that?
This Ghost Marshal Situ Tu clearly harbored ill intentions. They might as well lie low here first,
