Although Yin Baiqing had never mentioned his other family members during the two years he lived in Prince Yi's Mansion, it's hard to guarantee that he wasn't deceived by the people from Prince Mo's Mansion into revealing the truth.
Then, at that time, all the stories she had made up to Sui Zimo and Lin Caisang could be exposed!
"They just switched Wu'er out without taking him away directly," Prince Yi reminded her.
If Sui Zimo had taken Yin Baiqing away directly, the emperor would still have the opportunity to question Sui Zimo. But now? There's still an impostor in the National Teacher's abode. As long as Sui Zimo doesn't admit it, who can say he took Yin Baiqing?
And they are even less likely to speak up, because Yin Baiqing had already been bestowed upon the National Teacher's abode, to be Suyang's son. They don't have the right to make claims.
"An impostor is still impostor after all, they can't become real, can they?" Princess Consort Yi said.
