- Description from novelbuddy

Jianghu was in turmoil, an era of great strife. The leader of Great Qin wielded the Mo Blade, leaving the world battered and bruised. The ageless figures of Jianghu crouched upon the mountains, and with a single turn, they cast the entire world below them. Strong men measured the earth with their feet, and heroes of Jianghu could cleave the heavens with one sword, yet in the blink of an eye, they were drunk in the embrace of beauties. The Taoist carried his sword, the Scholar drunk on wine. Wearing tattered clothes, a beggar grasped a rotten branch and dared to storm the ancestral hall of the Taoist Sect. On the willow-lined causeway, in the long pavilion, a man who had sat withered for thirty years turned and stepped out, holding a peach blossom, with a flick of his wrist, he shattered ten miles of red candles. The era of Great Qin was renamed the Great Yuan Era. The youth with the Wooden Sword left his mountain village behind.
