A seasoned office worker is unexpectedly transmigrated while working overtime late into the night, arriving in the first secret realm of the Martial Spirit Continent: the Ice and Fire Purgatory. Inside, his memories merge with those of the biggest good-for-nothing in the city of Julu. He accidentally obtains mysterious treasures and god-tier martial arts, then gains the power of ice and fire after mistakenly eating the Ice Soul Divine Herb and the Fire Spirit Sacred Fruit. From then on, with ice fists and a fire sword, he sets out on the path from good-for-nothing to legend. He exposes conspiracies, overcomes traps, masters divine techniques, meets beauties, acquires rare treasures, establishes a sect, and ultimately becomes the Sword Saint and Fist Emperor, reaching the pinnacle of life.
