Zombie Agreement: Obtain the Bloodline of the Corpse Ancestor at the Beginning

(This is the first time for a newcomer to write a book. It has a single heroine, Ma Xiaoling, with the bloodline of the Corpse Ancestor (power not activated). In the early stage, she can only be regarded as an invincible mixed-race zombie who can learn Taoism. The plot has been greatly changed since the Qin Dynasty. If you mind, please come back and I welcome your suggestions.) Ling Xiao, a wage earner whose edges have been smoothed by life, was pulled by the system to travel through "Zombie Covenant", where he merged the bloodlines of the three great zombie ancestors at the beginning. Unexpectedly, the system actually pulled the wrong person, and ran away immediately after issuing the compensation.
