The water in the Blood River was as cold as ice, giving off a smell of blood.
The closer to the river bottom, the deeper the color of water was. At the bottom, it became completely dark red, and its temperature dropped to the lowest. For an ordinary Fish-Dragon Realm Monk, diving to the river's bottom would mean freezing to death.
Zhang Ruochen kept counting how deep they had gone. Ghost King Bloodmoon did not stop until they were already 1,000 meters deeper. Then she rushed to a black stone wall at the river's bottom and hit it with her palm.
Hua!
Rays of scarlet lights appeared on the stone wall and sketched strange lines into a huge formation 150 meters in diameter.
At the center of the Formation, there was a two-meter-wide crack, splitting to its left and right to leave a deep passageway. Looking at it from afar, it was like the eye of a devil.
