High Martial Arts Mistake the Primordial World for Reality, and the System Forces Me to Cultivate in Absurd Ways

At eighteen, Jiang Fan had achieved nothing. He thought his life would go nowhere, but he unexpectedly transmigrated to a future world where martial arts civilization had flourished and gained the strongest cultivation System. 【Ding! Host detected at the Primordial Wilderness. Main quest triggered: Join an Immortal sect.】 “First of all, this is a city... What? Going to school counts too?” 【The Host lacks a cultivation method. Side quest triggered: Obtain at least one cultivation method.】 “Heh heh heh, I get this one. You mean a textbook, right?” 【A suitable Dao companion for the Host has been detected. Please make a choice.】 “Wait, isn’t this a reptile zoo? Hey, you lizard! Why are you staring at me?!” … Thanks for asking. I’m in a high-martial world, but the System mistook it for the Primordial Wilderness. Luckily, the System really does hand out treasures! So loyal!! From the Dragon-Elephant Body Tempering Art to the Sixteen-Foot Golden Body, from the Five-Organ Essence Tempering Technique to the Nine Revolutions Profound Art, from “Hajimi” to the Howling Celestial Dog, from ice cream to the Red Armillary Sash! Years later, an otherworldly evil god that had devoured several civilizations awakens from the abyss, while star-faring races descend from the heavens, intent on keeping humanity in captivity... Atop the sea of clouds, Jiang Fan draws the Zhuxian Sword, the Emperor's Banner, the Sea-Calming Divine Pearl, the Book of Life and Death, the Taiji Diagram, and the Heaven-Opening Axe. Alone, he stands as a host of gods and Buddhas.
