This was Tuoba Lie's intention.
Just as he had said, if Nan Feng was willing to plead with him, to curry favor with him, then he wouldn't care where her heart was, as long as she was willing to stay by his side, he would treat her well.
He had effectively given her two options, first, to pick up cow dung and become the lowest of the low on the grasslands, or second, to return to him and curry favor, to become his wife; he would take her as his secondary empress, and he even didn't mind that she had borne another man's daughter.
But to his surprise, by the afternoon someone had already come to report, "Your Highness, the Second Prince, Lady Nan Feng is now on the grasslands."
"Doing what on the grasslands?" Tuoba Lie gripped his wine cup tightly.
"Your Highness, she is picking up cow dung."
The cup suddenly smashed, narrowly missing the ear of the person who had come to report.
