Humans—how very valuable they were.
In the hands of Evil Cultivators, humans could not only be taken apart and used, but also used whole.
Back when the White Lotus Sect was growing in power, it encountered quite a few "heretics," so the "heretics" could only atone with their families and themselves.
Talented women were offered to the Ming Wang and became Ming Wang Attendants.
Talented men were trained into Soul Saints and Soul Douluo, wrung dry of all their potential, then transformed into zombies and added to Death God Messenger's zombie army.
The rest, those with poor talent, whether male or female, would all become nourishment so long as they had nothing special about them. This group was the largest in number.
Their souls were either sent into Huo Yuhao's Hao Emperor Banner, left for Eunuch Gao to devour and absorb, or given to the Third Prince to cultivate the Yin Claw Hand.
Not only had this helped Death God Messenger break through to Titled Douluo, pushed Eunuch Gao's strength another step forward, and made the Third Prince's Yin Claw Hand stronger, it had also allowed the zombies Death God Messenger raised to grow by no small amount.
Previously, this zombie army's strength had already reached the level of White Corpse (rank: purple, white, green), but at the White Corpse stage, they could not move freely. Besides, an ordinary army of walking corpses was already enough to give the Sun Moon Empire plenty to suffer.
So these "premium goods" were all kept under Death God Messenger's continued cultivation.
Later, Death God Messenger brought them to the Star Luo Empire, found several places suitable for nurturing corpses, and kept cultivating them in secret.
The elders of Shrek Academy could not find Death God Messenger because Death God Messenger had been hiding
