"This is indeed the place where my fellow disciples and I practiced." Liu Xinlan's eyes were very complicated.
She actually didn't know the exact location of Du Zunlong's underground palace.
After Du Zunlong reached 'Quasi-Abyss' in cultivation, his situation became rather embarrassing. He changed his residence several times, and his disciples used a Teleportation Array to enter and exit this underground palace.
Later, after Liu Xinlan's resurrection and learning the knowledge of Outer Heaven Demons, she realized that this so-called teleportation technique was actually the curvature navigation technique, using runes to twist gravity, thereby creating a curvature bubble to travel through space and time.
Because the teleportation array was enormously expensive, they only used it once every twenty or thirty years.
Liu Xinlan could only rely on her own perception of heaven and earth to roughly infer the location of Du Zunlong's underground palace.
