Although the levels of these Demon Dao secret arts are not very high, it is evident that the Qi Family spent considerable effort gathering so many of them.
However, what piqued Zheng Yi's interest the most were three particular books.
"Essentials of the Nine Yin Gathering Evil Extinction Array," "Ghost Infant Cultivation Manual," and "Ghost Infant Manipulation Manual."
The first book Zheng Yi opened was the "Ghost Infant Cultivation Manual." He was very curious about how the Qi Family managed to cultivate these strange Blood Embryo Ghost Infants.
According to the records in the book, these Blood Embryo Ghost Infants take at least a hundred years to cultivate successfully and require a large amount of flesh and soul for nourishment.
