Mu Tianyan looked at the irregular pattern on the edge of the cliff and asked, "This is the teleportation array?"
Lu Zijia nodded. "Yes. This teleportation array has probably existed for more than ten thousand years. Many of the array formation materials are already old. It's better to be cautious. We should use new materials to repair them."
This array formation appeared more than ten thousand years ago. Perhaps other cultivators had really come to this world.
Mu Tianyan certainly agreed with this.
Suddenly, Mu Tianyan thought of a key point. "The teleportation array can only be activated with Spirit Stones, right?"
Lu Zijia: "…" This reminder from her man was quite critical!
She pretended to be serious and said, "Well, there aren't any Spirit Stones here, so we can only replace them with Half Spirit Stones."
