A thousand years later.
Humanity goes out of the solar system and establishes a galactic empire.
But the empire's borders were not peaceful.
At the edge of the Milky Way, there is a huge border spanning 100,000 light-years - it is the last barrier between human beings and the unknown universe.
Beyond the border, something is peeping.
Border guards have been held by descendants of the Qin Dynasty for generations.
Because two thousand years ago, the First Emperor Ying Zheng left an oral edict here:
"Without my order, you are not allowed to step outside the border."
And today, another emperor has arrived in this era.
He wanted to add another sentence after this dictation——
"Wutian Khan issued an edict not to cross the Milky Way."
