Fang Xi transmigrated, and not just once but twice!In the cultivation realm, I was timid and cautious; in another world, I unleashed my full potential!Never did I imagine that after millennia, I would become a powerhouse even within the cultivation world!

Set on a giant, almost finished bridge between Sadogashima and Niigata. Abandoned by the government, the bridge, and the giant man-made floating island at the center, has become a city of criminals and societal drop-outs.

Set in the same world as Durarara, but 15-20 years later. There is almost no overlap between Etsusa Bridge and the other novels.
