Lin Xiao, a down-and-out scholar, failed to pass the exams many times at the age of thirty-six. His family's wealth was depleted, he suffered from hunger and cold on his way back to his hometown, and he stayed in a dilapidated Taoist temple. His fate took a turn when a ray of blue light led him to discover an ancient book that recorded peerless martial arts. Not only did the lightning strike from the sky not kill him, but it helped him cleanse his scriptures and cut his marrow, and also awakened the memory of Xiaoyaozi, the Taoist master in his previous life.
