The Battle of Chouhei was a massive battle between the states of Qin and Zhao. Both sides were lead by the greatest generals of the era. On the side of Qin they were lead by Haku Ki with Ouki acting as his deputy while Zhao was lead by Ren Pa. The battle lasted for more than two years primarly because Ren Pa protected Chouhei for two years with a defensive iron wall that both Haku Ki and Ouki were unable to pierce through. However the Zhao king at the time lost patience with the stalemate and ordered a new general to replace Ren Pa which consequently led to their defeat.
Following the Qin victory against Zhao forces at Chouhei, Haku Ki concluded that he did not have enough supplies to feed the 400,000 prisoners of war. Putting the lives of his men as priority, he resolved to bury the disarmed prisoners alive, thus committing a mass murder that ensured the state of Zhao would hold a murderous grudge against Qin to its dying breath.
