They immediately leaped into the Extreme Yin River, intending to find the source of Killing Intent within it.
This was a tremendous merit—who would not want it?
Humans entering the Extreme Yin River made these ghostly creatures anxious. If the source of Killing Intent were seized by humans, it would mean losing a sharp weapon against humanity. How could these ghostly creatures so easily hand such an advantage to humans?
For that very reason, the ghostly creatures dove into the Extreme Yin River like mad, intending to drag out the humans who had entered it earlier.
Yang Chen slipped through the cracks and fished in troubled waters, putting on the appearance of someone pursuing humans as he jumped into the Extreme Yin River.
Once he entered the Extreme Yin River, it became much easier to fish in troubled waters.
The entire Extreme Yin River was filled with an immense amount of Killing Intent. With so much Killing Intent present, it was difficult for divine sense to clearly investigate what was happening within.
Yang Chen had previously been able to clearly observe Black Wind Underworld General's movements within the Extreme Yin River because he understood Killing Intent like the back of his hand. These currents of Killing Intent could not easily obstruct his sight.
Now that he had entered the Extreme Yin River, Yang Chen began to stretch his limbs.
The vast Killing Intent made it difficult for people to determine their own location within the Extreme Yin River. As for finding the source of Killing Intent, it was even more difficult without prior preparations.
More importantly, one moment of carelessness or insufficient protection could allow Killing Intent to invade the body at once, muddling one's consciousness.
Humans could avoid this only because they had Mystic Grass to protect their bodies.
