In the Chang'an star region of the Milky Way, the Ming Emperor Li Longji of the Tang Dynasty once commanded the Eighteen Yuans with the power of the "Khan of Heaven" and created an interstellar prosperous age. However, the brilliance of the golden dragon chair gradually dimmed, and Emperor Ming was obsessed with the enchanting illusion of the "Nirvana Dance", and the whispers of chaos echoed in his ears. The original body of Fan Yang Jiedushi, An Lushan, was bewitched by treacherous Qi. He held the "Eye of Hu Xuan" and led the Chaos Fleet to ignite the "Sirius Devouring the Sun" rebellion, vowing to burn the empire to ashes. In the midst of the galactic war, the loyal Guo Ziyi wielded the "Yaizu Mecha" and defended the Hedong Star Territory; the rebel general Shi Siming's "Yan Puppet Titan" crushed the Luoyang Star Port and sacrificed blood to Khorne. Prime Minister Di Renjie spent his life sitting on the "Interstellar Grand Canal", trying to save the collapsed empire, but he could not stop the expansion of the Chaos Rift.
The Great Food Empire rose from the Western Regions, using "mechanical methods" to cover up its aggressive ambitions. Psychic drones and plasma fleets are eyeing it. On Mawei Slope, Li Longji personally executed Yang Guifei in order to cut off the temptation of Slaanesh, but was seriously injured by Chaos and turned into a golden mummy. Guo Ziyi borrowed the power of Huihe Greenskin to recover the ruins of Chang'an, but the empire was torn apart, with vassal towns and star kingdoms separatist, and chaos roared endlessly. This is a doomsday carnival in the history of the interstellar Tang Dynasty. Sirius eats the sun, loyalty is useless, and only war and betrayal intertwine into an eternal elegy. Who can rekindle the star torch in the darkness?
