What is Zhang Qiling’s true identity?

The true identity of "Zhang Qiling" is the patriarch of the Zhang family, with the title "Little Brother". The character Zhang Qiling comes from the novel "Tomb Robbers Notes". The novel has been completed, but the latest update of the novel did not clearly indicate Zhang Qiling's specific life experience in detail. I think the life experience of the little brother will be explained in "The Flower of the Hidden Sea". We can know part of the life experience of "Zhang Qiling" through the previous plots in "The Flower of the Hidden Sea". For example: Zhang Haike and Zhang Haixing are Zhang Qiling's cousins, Zhang Ruishan and Baima is Zhang Qiling's parents respectively.

The Zhang family is a magical family with a mysterious background. His ancestors are descendants of the Queen Mother of the West and have lived in the Changbai Mountain area for generations. Their purpose is to protect the secrets behind the bronze door. In order to protect this secret, this family has been constantly striving for self-improvement. Under the leadership of the patriarch, generations of generations have been rigorously trained with clear divisions of labor. They have continuously strengthened themselves in business, politics, and tomb-robbery prevention. Such is Zhang Qiling's life experience.
