If it were only this, Zhu Yu might feel indignant at Emperor Jin's "generous leniency," but wouldn't be surprised, let alone shaken to the core.
Besides the handling of Zhao Bi by Emperor Jin, the secret letter also mentioned another matter.
Regarding Zhao Bi's embezzlement of tribute, Emperor Jin could overlook it out of old sentiments. However, Zhao Bocai's private recruitment of government soldiers, illegal manufacture of weapons, and seizure of land to hoard grain and troops, could not be so easily bypassed.
From the secret letter, Zhu Yu learned that when Emperor Jin initially dispatched troops to capture those government soldiers, they encountered fierce resistance from Zhao Bocai's subordinates, turning the capture into a siege, thus significantly escalating the severity of the situation.
After the imperial guard returned from besieging Zhao Bocai and his followers, they reported on the government soldiers of the Zhao Family committing senseless killings outside.
