Two young women and two middle-aged men were standing by the side of a long and deep river, but the water in the river was black and gave off poisonous fumes, and they even had to protect themselves with energy to avoid being exposed to the poison. In the area around the river, there were also many skeletons of humans, beasts, etc.
The four people were Murong Mengxin, Dugu Yan, Song Ming, and Zhang Wei. They actually wanted to fly across the dark river, but there was a flight restriction formation in the area, so they couldn't do it.
Song Ming then took a bone and threw it into the river, and they took a deep breath, watching the bone dissolve into the river water. "Yan'er, this river is too poisonous, there's no way we can cross it."
