The chamber below looked quite complex, and it might take an ordinary cultivator a long time to figure it out. However, for Ning Cheng, it wasn't a problem at all.

Ning Cheng pointed to the transmission formation and said, "Not long ago, this formation was activated, and there are still spatial fluctuations around it. Luo Fei, come up with me, and we'll teleport to see."
