Before he died, my grandfather drew seven copper coins on my palm. He said they were money to buy my life.
When I was eighteen years old, a heavy rain washed away my ancestral grave. No bones of my grandfather were found in the coffin, only a copper coin turtle engraved with talismans.
Following the clues, I entered the world of Feng Shui to tell people's fortunes, but gradually I discovered that the birth dates of those who came to me to change their fortunes were actually similar to my fate of premature death.
Until I was invited to explore the dragon veins of the Qinling Mountains, and saw my grandfather penetrated by nine dragon-locking nails in the giant bronze coffin. Under him was a formation that reversed yin and yang - the eyes of the formation were my seven copper coins.
"Good boy," the grandfather in the coffin suddenly opened his eyes, "Grandpa lent you your life for fifty years. Today is the day you have been waiting for."
