"Tap tap tap~~!"
The strange footsteps sounded again, evidently Li Lina had already stood up and left the vicinity of the cave entrance.
Seeing this, Mu Rufeng immediately stretched his head over to the entrance and looked inside.
Inside was a small space of about fifteen square meters, its walls lined with pipes, clearly a piping room that Li Lina had discovered and turned into a secret spot.
The room also contained various items, such as maps, personnel relationship charts, work schedules, and more.
At this moment, two-thirds of the entrance had already closed.
Mu Rufeng glanced at Li Lina, who was facing away from him, and calculated the time. There was just over an hour left, plenty of time.
Without hesitation, he used Instantaneous Movement to enter the room.
Of course, to prevent accidents, Mu Rufeng had picked up a screw from the ground and placed it at the entrance before going in.
This way, even if the entrance closed completely, a small crack would remain.
