Yunyu turned his head, and when he saw that Michael was chasing him relentlessly, Yunyu panicked. He used all his energy to run as fast as he could, the best possible thing he could do right now was to run away, that was it.
"Don't run!" Michael kept chasing Yunyu through this forest. They were deep in the forest, and the light was getting dimmer because it was already dusk. The Duke was really fast and in the end, Michael was still a human being, he finally lost his breath and tripped on an overgrown root.
Michael fell to the ground, he winced in pain. He had sprained his ankle badly.
Michael took a breather on the ground, because he used up all his strength to chase the Duke who had disappeared. He had a feeling that the Duke was not a regular human, his instinct already saw that Duke Damien was possibly a vampire.
