This one word, "grandma" though softly spoken, struck Old Lady In like a thunderclap, making her scalp tingle and sending a shockwave through her entire being.
It was as if an electric current coursed through her, causing her heart to pound and her fingertips to tingle.
She stared dumbfounded at Si Fuqing.
Old Lady In, usually so composed and knowledgeable, was at a loss for words.
In Qiushi was similarly stunned.
He had mentioned Si Fuqing's resemblance to In Beichen to Old Lady In because he indeed saw a striking similarity, but mostly it was due to his longing for In Beichen, using this as a mental solace.
Even In Qiushi had not anticipated that Si Fuqing was truly In Beichen's daughter!
"Qiushi, what-what did this child call me?" After a moment, Old Lady In finally reacted, gripping In Qiushi's hand tightly, her voice filled with disbelief. "Did you hear that? What did she call me?"
