The creature hovering behind Liu Nan at this moment was none other than the first mammal specimen they had seen—a black cat.
The black cat was now leaping towards Liu Nan, pawing along the uneven wall. When it saw He Ao, it violently arched its back, attempting to spring to the side.
At the same time, a bull, its body flushed red, also charged at He Ao.
He Ao did not take out the bull directly. If he had finished the fight quickly, the black cat would not have been easily lured out.
But after such a long battle, He Ao had already constructed a complete combat model of the bull in his mind, so he was actually leading the entire fight.
During the combat, he always maintained the right distance, misled the bull into missing its attack, and broke away from the combat to appear behind Liu Nan the moment the black cat emerged.
However, this opportunity was extremely brief; the bull, having missed its target, quickly recovered and charged at He Ao once more.
