Mo Fang had parents that could give him anything if he wanted, but he didn't want anything,Or one can say he couldn't.
He was a 17 years old boy who was destined to die on the next day, which was his 18 birthday, all the doctors in the world said he can't live one more day than that if he didn't have the transplant which would give him 2 additional month but he refused to have it.
The reason behind it is a girl of age 13 also had the same problem but she would live her whole live but he would not. He decided to give it to her,
while at night 12:00 waiting for his death with his parent crying in their arms. Slowly his consciousness was fading away he waited for his death.
He was saw a person who was King Yama then in confusion he asked "am I not dead". King Yama said "yes, you indeed are dead". Then he explained because of his good deeds the people in heaven decided to send him to the upper world where people cultivated to the peak of the world.
Then while he was sending him to upper world something unexpected happened in hell so problem occurred to his reincarnation to upper world he fell in hell and he died for second time because of his extreme bad luck.
