It was a spiritual world—one that came from within the flame.
Ou Yangming experienced something similar in the past when he was inside the cottage in the Ni family's secret realm. Nonetheless, the secret realm that was set up had many loopholes and would turn into an undefended world if a cultivator with great mental power entered. As such, it could then be accessed by anyone.
The young fellow guessed that perhaps it had been such a long time, hence the formation map left behind by the Ni family's seniors became less effective.
As compared to the Ni family's formation map, the spiritual world that Ou Yangming entered at the moment was entirely different.
Even with remarkable mental power, Ou Yangming could not sense any weak points in the spiritual world at all as though he entered a real universe. It made him alert, and he vaguely realized that the little bird's mental power was probably greater than his.
