Initially, upon hearing the words of Master Yan, who said that Teacher Jin of Dazhou had only daughters and no sons, and thus no grandsons, he took precautions and sent someone to investigate, and in the process learned about how Nangong Ye was doing over there and whether he had recovered.
But the person he sent reported that a new Crown Prince had recently returned to the royal family, and the Emperor was seeking medical advice everywhere for him. If someone could cure his poison, they could inherit a salary for generations, and their descendants would enjoy perpetual peace.
From this, they concluded that the Crown Prince must be Nangong Ye.
At this point, it was not difficult to deduce that it must be Nangong Ye.
The Emperor sat in a daze, hardly believing that Nangong Ye also had royal blood and could one day be a competitor if conflicts arose between the two nations.
But the Emperor wished that such conflicts would never arise.
