In July of the first year of Qin II, it rained heavily. In the prison camp at the foot of Lishan Mountain, an ordinary clerk, Qin Hai, accidentally discovered three volumes of bamboo slips that should not exist during an ordinary document arrangement - they were fragments of the imperial edict that was not issued before the death of the First Emperor, and on them was written a name of a person who had been erased by history. Three months later, the beacon fire was ignited in Daze Township, and the first crack in the sky of the empire was opened. Qin Hai took these three bamboo slips and embarked on a road of escape, from Lishan to Xianyang, and from Xianyang to Mangdang. The secrets in the bamboo slips were like an invisible rope, tightly binding him to the collapse of the empire and the rise of dynasties.
