As they were leaving, the assassin handed Su Yang a jade pendant.
"The endless starry sky is vast beyond measure. Once you get lost in it, you may never find your way back," the assassin said. "This jade pendant will allow you to sense the position of the moon while in the endless starry sky, so you can fly back in that direction. Also, this pendant can unlock the seal on the moon. If you want to return, you must use this jade pendant, so don't lose it!"
Su Yang nodded; he didn't need the assassin to tell him to know how precious this jade pendant was.
