Plot synopsis: According to an old saying, the life you have in this lifetime is a karma of what you did in the last. What if you can go back to your past lives and change your actions? Ye Yin's master can look into past for the cause, examine the present for the adversity, and see into the future for the solution. He has the ability to send people back and forward in time and to any place. All he asks for is one sincere drop of tear. By helping others resolve their past conflicts, perhaps, the master and her can move closer to changing their own fate.
