After Qin Xiaogong's death, King Huiwen of Qin became the new monarch of the State of Qin. King Huiwen of Qin realized that Shang Yang's powerful hand had endangered his ruling power.

The King of Qin Huiwen just succeeded to the throne, and the DPRK minister told Qin Huiwen that Shang Yang had rebelled again.
