A Colossal Shadow in the Monster World

In his original world, Ye Yun jumped into the water to save someone who was trying to end their life, only to be killed by the person he had rescued. As he died, he obtained a mysterious legacy, and his soul transmigrated to a world filled with monsters. Some monsters were famous, others were unknown, and their strengths varied. All of this was closely connected to the darkness fighting against the light.
