Xukong had been deep in cultivation for quite some time.
He had known that Lin Mu was entering an inheritance ground and that it was an uncharted territory. But he didn't mind it and knew that Lin Mu would be able to handle things. Xukong himself was close to a minor breakthrough in his cultivation and was fully focused on it.
Of course, he could sense when Lin Mu was going through teleportation channels or through the space, but it didn't bother him since it was all normal.
For Xukong, Lin Mu was finally at a level where he didn't have to watch him all the time. Even if he was entirely unable to contact him, Lin Mu was capable of handling himself, or at the very least escape. He had all the skills in his arsenal and had planned for it.
But there was a limit to which Xukong gave him a freehand.
He wouldn't have minded if Lin Mu was wandering the void or swimming in space.
But he certainly didn't expect him to be jumping into a pit of death!
