My name is Hong Yuan. I'm 18 years old, with an F-rank fire talent, and I'm universally regarded as the school's biggest loser. While everyone else cultivates spiritual energy and flies through the skies on their swords, I practice a battered old book called the Eight-Nine Arcane Art, bought from an old beggar. Through eight transformations and nine cycles, it returns to pure yang, tempering the body into a sacred vessel that grows stronger with every beating. My ex-girlfriend blocked me after discovering my F-rank talent, but the childhood friend I'd always overlooked has stood by my side all along. Beyond the Great Wall of the Heavenly Chasm, the demon race has threatened the land for a century. No one remembers the figure who once shouldered the fate of the Nine Provinces. They call me a good-for-nothing. How ridiculous. From today onward, I will write the future diary of this so-called loser myself.
