Sixteen-year-old Feng Jinyun,
Thirty-two-year-old Su Letong.
One is a young man with a complicated life experience,
One is a man whose family was brutally exterminated when he was fifteen years old.
The narcissistic and sinister year attacks,
Self-love, wealth and lowly uncle suffer.
When they finally got results after going through so many ups and downs,
But he found that the heartless person who smiled and laughed all day long was going to leave him and leave this world.
Feng Jinyun slit their wrists and watched the bright red blood pouring over the mutton-fat jade.
He said: "Just use the blood of both of us to water it. Think of it as a blood contract. I want you for three lives."
Both returned to the twenty-first century.
When Su Letong stood on the podium and gave a lecture,
He heard a familiar voice.
"Su Letong."
"Hello, Teacher Su, my name is Feng Jinyun."
