Meng Qianqian asked, "Then why was he made Crown Prince?"
Si Snake replied, "Because he has an heir."
Ji Li asked curiously, "Emperor Liang's sons are all childless?"
Si Snake answered, "There's a rumor among the people. Back when Emperor Liang was still King Qin, he wrongfully ruled on a case. The other party cursed him before their death, saying the Qin royal bloodline would be cut off. After that, no new infants were born in the Qin royal family. Later, the Qin royal family sought the help of a Daoist to perform a ceremony. Although children were born afterward, they were all daughters."
"But not long ago, a mother and son came to the Prince Qin Mansion. After verification, it was confirmed that the woman had a brief relationship with the second son of King Qin when she was young, and gave birth to a son – in other words, King Qin's legitimate grandson."
