Cultivating the Corpse Luo Scripture requires an environment thick with Corpse Qi.
Graveyards, Chaotic Burial Mounds, and similar places were the most suitable.
It also required poisonous insects from these places to create poisons. To put it bluntly, the cultivation involved using various types of Corpse Poison.
The side effect of this cultivation was that one would gradually become like a Zombie, neither human nor ghost.
The slightest misstep, and one would become a literal corpse.
In short, these cultivation requirements alone were enough to deter most people.
This was also why, despite being a High Grade skill with a clear path for cultivation to even higher grades, its value wasn't considered that great.
Otherwise, Zou Feng wouldn't have obtained it so easily.
