In 210 BC, the First Emperor "died" in a sand dune. In fact, he fell into a deep sleep due to a falling "core of the outer ark", and his body and consciousness were sealed.
In 3267 AD, an interstellar archaeological ship discovered an ancient human coffin sealed in a strange force field at the "relics of ancient civilization" (i. E., Earth) on the edge of the galaxy. During transportation, the spacecraft was attacked by interstellar pirates, and the energy leaked accidentally activated the coffin.
Ying Zheng woke up in a strange metal room, facing talking machines, weird alien creatures, and bizarre holographic projections. It took him three minutes to accept the fact that "I seem to have arrived in the future", three hours to learn the interstellar lingua franca and hack into the spacecraft database, and three days to figure out the basic structure of the interstellar era: federation, empire, chamber of commerce, pirates, star bug threat, virtual currency, and energy crisis.
