"What's on the plane?"
Lu Ban immediately became alert. He listened carefully but did not hear any strange noises.
At this moment, they were high in the sky, at an altitude of ten thousand meters; any accident would mean trouble for everyone on board the plane.
"Look."
Feng Yu directly opened the partition door for Lu Ban, letting him look outside.
Lu Ban looked out and at first glance, it seemed like nothing had changed, but he quickly realized something.
It was too quiet.
Even in first class, there should be flight attendants back and forth attending to the guests, and moreover, the entire plane seemed quite old, not at all as new as the one Lu Ban had seen before.
"A peculiar phenomenon?"
Lu Ban quickly reacted.
