Before time travel, Bai Ye was a modern social worker with an optimistic personality, a bit salty but with a strong bottom line. He valued love and justice. His lifelong dream was to lie flat and not have to look at the boss's face.
After traveling through time, Bai Ye transformed into an ancient black divine dog. He started out as a newly weaned infant, retaining the complete thinking and memory of humans. As his body grew older and his magical powers gradually improved, Bai Ye became Xiaotian, the loyal dog follower of Erlang Xiansheng Zhenjun Yang Jian. As the number one plot savvy brother in the Three Realms who is familiar with mythological novels such as Fengshen and Journey to the West, Bai Ye relied on his foreknowledge of myths and his exclusive golden finger to escape the fate of a tool man step by step. From a pet attached to Yang Jian, he grew into a dog god who is equal to Yang Jian and is respected by the three worlds.
