Chapter 2549: Cai'er
Under the guidance of the Colorful Butterfly Divine Venerable, Lin Feng and the Colorful Butterfly Divine Venerable arrived at the foot of a mountain on Spirit Butterfly Island. As Lin Feng was puzzled about what the Colorful Butterfly Divine Venerable intended to do here, the Colorful Butterfly Divine Venerable suddenly flicked his sleeve, and a cave emitting a chilling icy aura appeared at the foot of the mountain.
This situation took Lin Feng by surprise. He could sense that this was not any Formation but a special kind of Dharma Treasure, akin to the security door locks back on Earth. He couldn't understand what was hidden inside and why it was so well protected.
Following the Colorful Butterfly Divine Venerable, they went deep into the cave. When they reached the end, a hall emerged.
