A day in the world, a thousand years in a dream.
Young cultivator Ye Xiaoshan spends twenty years training in the mountains. Simply by sleeping, he awakens memories of his past life and improves his cultivation. In just twenty years, his rate of progress is enough to leave the old man training alongside him in the mountains green with envy.
On Ye Xiaoshan's twentieth birthday, the old man decides it's time to send him down the mountain. Before he leaves, Ye Xiaoshan even snatches a treasure the old man has kept for years. Following scattered fragments of memory, he carves out a place of his own in the world.
He enters the jianghu, rids the land of Japanese bandits and slaughters their forces, and meets the heroes of the martial world. He enters the imperial court, seizes power, unifies the realm, and brings a new dynasty to the throne.
He takes joy in helping others and is generous to those in need. Whenever he meets a lonely young woman on the road, he is happy to help her with everything he has. He also helps his dear older brother look after his sister-in-law.
