After all, Ruobing was Old Madam Xi's adopted granddaughter.
They had years of memories together. The emotional ties were too deep. If Old Madam Xi was willing to forgive her, then Ruobing would escape unscathed.
Therefore, Xinghe had to set up the stage for Ruobing to fall…
She'd laid down the choices before Ruobing, either she admitted her mistake or shamelessly continued on with the knowledge of her mistake.
Obviously, Ruobing chose the latter…
Accidental mistakes were forgivable, but someone who pressed on despite knowing her own wrongdoings? Such people didn't deserve forgiveness.
Xinghe knew with certainty that the faulty product would injure Old Madam Xi and she hoped the light injury would amplify her disappointment and anger towards her adopted daughter.
In any case, even if Old Madam Xi could somehow find her heart to forgive Ruobing, her ex-husband would not…
It would be the same for the entire Xi Family.
