Yun Yao, a miscellaneous spiritual root disciple who transmigrated to the immortal cultivation world for eight years, has always been regarded by the sect as a mad and comical joke. After the grand sect ceremony, he awakens the grand reputation system, acquiring grand energy value to raise his cultivation realm through others' shock and awe, accompanied by the haughty system spirit Ling Yue. He sits naked in enlightenment and repels fierce beasts, making a name for himself in a single battle, and is accepted as a personal disciple by the sect master. Together with companions like Su Qingli, he sets out on a journey to find treasures, collecting ancient divine artifacts along the way while encountering endless amusing anecdotes. With the extraterrestrial seal loosening, companions sacrifice themselves one after another, and the divine artifacts' power is devoured by the demon lord. The playful Yun Yao sheds his frivolousness, wields the Lingxiao grand sword, puts himself in danger to confront the Abyss Void Primeval Demon, completes his transformation in desperate straits, and shoulders the heavy responsibility of saving the world.
