The Great Dao of Zhen Yuan in the Wilderness

I, Zhen Yuan Zi, just want to ask why Laozi, Primordial, Tongtian, Nuwa, Jieyin, Zhunti, and the others, who are also innate gods, can become saints while I can only become the ancestor of earth immortals.

This was a self-improving Zhen Yuan Zi.

The Witches and Demons would undergo the Cultivation Tribulation to become Saints, and they would undergo the Infinite Cultivation Tribulation to achieve the Great Dao.
