The Life and Death Coffin emitted a faint mist that formed a gray aura and surrounded everyone. Wang Zhong had seen this technique before. Mu Zi had used this in the Decapitation Canyon and the desert. The aura of the Life and Death Realm surrounded them, allowing them to hide in between life and death. It was like walking in a narrow crevice between the borders of the two worlds, tricking the vision and senses of almost all living creatures. The mist even had an aura that living creatures hated, causing them to disperse. The venomous insects that buzzed and flew in the air did not pay any attention to the three of them and flew over their heads. A few insects who flew low almost bumped into Napier but flew around him as if he was a rock. The insects did not even look at them. Napier was shocked by this. He broke out in cold sweat, but he was also secretly happy.
