In the next moment, Li Yun appeared before a dark cave.
The pitch-black cave was like the mouth of an ancient behemoth, swallowing all light. Any light that approached the entrance immediately dissipated without a trace.
This was the Endless Demon Cave.
Inside the Endless Demon Cave, a batch of demon beasts appeared every fifteen minutes. Each batch consisted of exactly one hundred beasts. As the rounds increased, the strength of the demon beasts would grow progressively stronger.
With every additional round, the strength of the demon beasts would increase slightly. Every five rounds, their strength would undergo a significant leap.
There were thirty rounds of trials in total.
From the sixteenth round onward, the demon beasts would be at the 9th level of Heavenly Core Realm. As for the twenty-sixth round, every single demon beast would be comparable to a powerhouse at the 1st level of Spirit Manifestation Realm.
