The Zhous' ancestral founder, Zhou Wufeng.
He was the one who obtained the Corpse Demon Art back then.
When he obtained the Corpse Demon Art that year, he actually got two manuals of the cultivation technique in total.
The complete Corpse Demon Art was composed of two cultivation techniques, which were divided into a main cultivation technique and a secondary cultivation technique.
The main and secondary cultivation techniques were largely the same, only the main one was more complete than the secondary one.
After obtaining the Corpse Demon Art, what Zhou Wufeng handed over to the Zhous to cultivate was the secondary cultivation technique of the Corpse Demon Art. The main cultivation technique was cultivated by him alone; the rest of the Zhous, including the deceased ancestor Zhou Niantian, didn't even know that the Corpse Demon Art had a main part.
