Xia Tuanzi thought very simply, as long as Prince Wu died, wouldn't his sister no longer have to marry into that family?
She wouldn't be held back for a lifetime.
As for the capital crime of assassinating the current Prince, which would lead to the annihilation of one's entire clan, none of these were within Xia Tuanzi's considerations.
Anyway, he had to ensure his sister was safe.
By the time Xia Ningxing realized that Xia Tuanzi was missing, her heart immediately sank to the bottom.
His bed was still in the same state as she had arranged it yesterday, suggesting that he must have left last night. If he had succeeded, he should have already returned by now.
But now that daylight had broken, there was still no sign of him.
Clearly, he had been captured!
He couldn't come back!
