A little boy just over a month old is found in a trash can by a middle-aged man who makes a living scavenging. He takes the boy in and names him Tang Chao Xiaotian.
From then on, Tang Chao Xiaotian becomes a familiar sight on the man's handcart. By day, they collect rubbish; at night, they return to a ruined temple, where the man teaches him to read, write, and survive by candlelight.
When Tang Chao Xiaotian is seven, the man sends him out into the world to fend for himself, and he becomes a beggar. Through a series of chance encounters, Tang Chao Xiaotian learns the Qiankun Acupoint Technique, the Nine Heavens Profound Palace Art, and the Lightning Meteor Footwork. He awakens the Heavenly Eye, which lets him read the memories of all things, and gradually grows into a legendary martial arts master, a university medical professor, and a provincial criminal investigation expert. He also acquires the Ten Great Ancient Divine Artifacts. Relying on his own strength, he defies the powerful to defend kindness and justice in the world. He has infiltrated gangs by night, recovered national treasures, pursued drug traffickers across thousands of miles, punished human traffickers, captured spies, and solved headless murder cases and cold cases left unsolved for years. To help more of the poor and vulnerable, he first establishes a waste collection and recycling company, which grows into a group with nine businesses and assets worth tens of billions. Yet he never seeks a life of luxury. Instead, he lives frugally and gives back to society, establishing free orphanages, nursing homes, public hospitals, and schools teaching both civil and martial arts for the poor and vulnerable. His efforts bring a little light to the world. What kind of legend will he make?
