Chapter 1409: Invasion

After examining the piece of the skull for a while, Lin Yun put on a mysterious smile.

The King of Nightmares' body was very huge, but his skull was only the size of a baby's. He was also the only ghost who had bones.

This piece of the skull was the one from the back of the skull. It was often neglected.

In terms of the power they contained, the brow ridge was the best one, the piece of the skull in the center was the second-best, and the back piece was the worst one…

Lilith obviously played a trick on him. She had given her the bone that contained the least power…

But Lin Yun smiled because this piece of the bone was the most suitable as the key to the Kingdom of Nightmares. It would essentially open the back door of the Kingdom of Nightmares. If he had the brow ridge, he would have to go through the front door, which could be very dangerous.

But he could try the back door. Although it was also dangerous, it was not entirely hopeless.
