Big Yellow is the servant of Immortal Monarch Luhe in the Sea Market.
The other person is Chen Xuan.
In the past, Chen Xuan betrayed Immortal Monarch Luhe, and ultimately his will merged with other Ancient Cultivators to give birth to Taoist Man.
Taoist Man somehow preserved Chen Xuan's physical body and used it to find Immortal Monarch Luhe's Immortal Mansion within the Sea Market, attempting to acquire the treasures left behind by Immortal Monarch Luhe.
This is why, when Wang Ba and the others first saw the Immortal Mansion, its gates were already open.
During this process, Taoist Man deceived Big Yellow, tricking his physical body away from the Immortal Mansion.
The reason Big Yellow can exist up until now is due to the unique rules of the Immortal Mansion, which can maintain his consciousness.
Once he leaves, he will revert to a mere corpse.
