The spiritual energy of heaven and earth has dried up, cultivation civilization has fallen into dust, the once flying sky and earth have become street performers, and flying swords to deliver letters are no better than pigeons to deliver letters. In this world nicknamed the "Apocalyptic Age", Lin Xiaoman, a useless young man who has awakened the "Tucao Energy System", discovers that as long as his complaints are accurate and heart-breaking enough, he can obtain valuable "complaint points" that can be exchanged for spiritual stones, skills, and even a hint of recovery. So, holding a copy of "The Self-cultivation of Gang Jing" in his left hand and a big horn in his right hand, he started working as a waiter at "Juxian Village" (now renamed "Youjian Inn"), determined to use his mouth to spray a path to heaven in this world full of weird and wonderful people! "Fairy, has your face-preserving technique expired? Wrinkles can kill a fly!" "Fellow Taoist, is your flying sword rusty? It's not as fast as I can throw my slippers!" Let's see how Lin Xiaoman uses his mortal body to fight with the group of cultivators, defying the sky, the ground and the air, and creating a new world amidst the laughter and laughter!
