Fan Yuan is also known as Dongjun, a person of unknown origin, unknown age, no past, and a loner.
He possesses incredible power, and those who have seen him call him "The Ferryman".
You make a wish to him, and your wish can be to go back in time, or to see the person you want to see. As long as you meet the standards, no matter how small your wish is, he will help you achieve it.
When your wish comes true, he will take something from you. What he wants can be a drop of your tears, a drop of blood from your index finger, a precious thing, or your soul... In addition, you don't need to pay any price.
