Chapter 863: Not Welcome?

Around the Core Tower were more than ten engravings of giant dragons, which coiled around the tower. They looked life-like and awe-inspiring.

The dragons' facial expressions were ferocious, and it was as if they were looking down on the mortal creatures below.

Ye Chen could even sense an invisible pressure enveloping him that exuded coldness. It seemed that someone was warning him that any disrespectful actions would lead to certain death.

Even the blood dragon in his body felt something and roared angrily.

"It seems like the Core Tower is a divine artifact. I wonder what's on the top level."

Ye Chen looked around again and closed his eyes to sense his surroundings. Soon, he realized that there was an ancient formation around this place.

Although Ye Chen was quite skilled in terms of formation and talismans, he could not deduce what formation this was, nor could he find its formation core. In a sense, it was an almost perfect formation.
