After his soul leaves his body, Qin Shi Huang discovers that the spiritual energy on the continent of Jiuzhou is too sparse to support cultivation. Only then does he realize that the "elixir of immortality" Xu Fu offered him was actually an advanced alien teleportation array capable of tearing through space. It drained the world's spiritual energy and drew an even more dangerous interstellar civilization to invade.
He abandons his body and enters the core of the great formation beneath his mausoleum, secretly directing the Twelve Golden Men to fire their annihilation cannons and repel the first wave of the interstellar fleet. But he discovers that the spatial rift above the Nine Tripods is being plugged by the Dao Ancestor with his own flesh and blood. The truth behind the "ascension to the celestial realm" that has endured for ten thousand years is that nameless cultivators burned their flesh and blood to fend off an alien invasion?
When interstellar railguns orbit around Qin Shi Huang and he holds the ancient sword Tianwen, gazing down upon the sea of stars,
he finally understands that the great achievement of "conquering the Six Kings and unifying the Four Seas" was merely the prelude to arming this planet to the teeth and preparing it to face the apocalypse.
My sword shall strike only the demons from beyond our borders. "The realm may be contested and plunged into chaos, but it belongs only to the people of Huaxia. Should any foreign enemy dare lay so much as a finger on it, the Qin sword will sweep their lands clean and wipe out every trace of them!"
