Ren Feifan stood up, looked around, and found that it seemed as if the area was swallowed by darkness, without a trace of light.
Ren Feifan conjured a flame in his hand, quickly illuminating the surroundings.
But when he saw clearly, his face was filled with shock because he discovered ancient runes and various formation patterns in all directions!
It took him more than ten seconds to fully realize it!
This dark place turned out to be the very core of the Lock God Formation!
In other words, this place is gathered with ancient formations!
Ren Feifan carefully examined each line of text, even reaching out to touch them continuously.
His accomplishments in formation at the Hidden Gate were still impressive, but compared to Lin Langtian, he was at best a mediocre Array Master. However, even a mediocre Array Master would see their comprehension of formations soar several times over after seeing the core of this ancient formation!
