"Creak creak creak..."
A series of crisp sounds of bones colliding rang out.
These death creatures came in various forms, resembling humans, monsters, giant dragons, and so on.
But there was one commonality, each one exuded a very strong death aura.
The death aura each exuded was almost comparable to that of the skeleton he had just encountered.
In other words, these thousand-odd death creatures in front of him could rival a thousand Immortal Emperor Cultivators if placed outside.
Zhu Fei was astonished.
He couldn't imagine what kind of place this was now, capable of nurturing so many terrifying death creatures.
At present, if he weren't in possession of the Death Heavenly Book, traversing this Immortal Emperor tomb would definitely be an extremely dangerous task.
Thinking of this, a golden light suddenly flashed in Zhu Fei's eyes.
