Li Yanran was not like Lu Chen, who could see through the Chaos Spirit Power and thus discover the hidden beast.
But once the beast realized that the creatures outside the crack had no absolute way to enter, it turned its attention downward.
It burrowed through the crevice's walls again, watching the area below with caution, and then sensed a pure stream of Wood Spirit Power!
Just as Lu Chen had guessed.
This creature, too, was an ancient beast, yet different from the others.
It was the guardian beast of the formation here!
At first, upon discovering the changes in this place, it thought someone was trying to intrude into the formation.
However, Lu Chen's Chaos Spirit Power naturally suppressed it, and the guardian beast didn't hesitate to retreat into the crevices.
That's why Lu Chen had not detected its presence; had it not been for the commotion caused by the external beasts earlier, there would have been no chance of seeing this beast again.
