After an unfortunate stroke of luck, Ge Wen unexpectedly finds himself on Terra. The good news is that this isn't Warhammer's Terra, but the Terra of the Arknights setting. The bad news is that he's arrived at the wrong time, more than nine thousand years before the main story begins.
After spending some time literally scraping by, he becomes the greatest warrior under the First Demon King, Yuan Zhuzhe. He finally brings back Originium, masters the Originium Arts of fire, teaches his people advanced culture and technology, and turns the tide on the front lines against the Divine People and the Ancients. But during yet another mission to search for relics of the Previous Era, he loses consciousness...
When he wakes up again, he has changed from a Teekaz into a Sankta and appeared in Laterano more than nine thousand years later. To his regret, all his previous efforts have failed to alter the course of history. The Durin live underground in the rainforests of Sargon, the Oni and Anasa are scattered abroad, and the Sarkaz and Sankta, whose hatred stretches back thousands of years, are still locked in conflict.
"It's time to put an end to this conflict! I'll reunite the scattered branches of the Teekaz and make the Teekaz great again!"
