The Ji and Shen families have been looking for three bodies that have coinciding birth characters. However just as Song Yan said it was too difficult, they couldn't find any bodies that had the same birth characteristics as Ji Ziyi and the other two.
In the end just as Ji Zhuang Guang and Shen Hanjing felt that they were going to fail, they received information from the head of an orphanage. He was willing to sell the bodies of the three girls who were found dead at the gates of the orphanages. Turns out that they went to the training camp after winning the scholarship.
These three girls were sisters and were abandoned at the orphanage by their parents as they were girls and they wanted a son. Because of this reason, the three girls wanted to grow up and become someone of importance, they would have never imagined even in their wildest dreams that they would end up dying.
