Medical student Lu Hao is thrown back to the Qin dynasty by a time machine. His mission is unexpectedly to help the emperor expand his territory even further. His special advantage is simple: summon people. Chancellor Zhuge Liang lays out a century-long national strategy, generals lead lightning cavalry to sweep across the steppes, and experts from various dynasties arrive one after another to transform logistics, the economy, military equipment, and infrastructure. Under a mysterious force of correction, the enemies grow stronger at a crazy rate. Meanwhile, Lu Hao watches the emperor steer the empire while enjoying the spectacle, as an all-star lineup gets down to business.
