Floating behind Liu Nan at that moment was the mammal specimen they had seen first—the black cat.
The black cat was leaping across the uneven wall toward Liu Nan. The moment it saw He Ao, it arched its body sharply, intending to spring away to the side.
At the same time, the crimson Bull charged at He Ao.
He Ao did not finish Bull off immediately. If he ended the fight too quickly, the black cat would not be so easily lured out.
But after fighting for so long, He Ao had already built a complete combat model of Bull in his mind. In reality, he had been controlling the entire battle.
Throughout the fight, he had kept the right distance. The instant the black cat appeared, he misled Bull into missing, then broke away from the fight and appeared behind Liu Nan.
But the opening was extremely brief. Bull, having missed, quickly reacted and charged at He Ao again.
If Bull held He Ao back, the black cat would be able to escape completely.
