I Am Reborn as an Urban Immortal

The No. 1 Sword master in the immortal world failed to survive the tribulation. His soul traveled back to the modern city and possessed a high school student who jumped off the building after being bullied by his classmates. He discovered that although the aura of this world was thin, it still concealed the relics of ancient cultivation civilization - it turned out that the earth was once the center of all worlds, and the fairy world was just the "backyard" opened by those who ascended back then.
