Observe All Kinds of Techniques from the Handyman in the Martial Arts Hall

In a troubled world of martial arts, human lives are like grass. Lin Mu started out poor, guarding two shabby houses, but even this small amount of property was coveted. Until he discovered that he had the ability to secretly replicate the skills he had seen. A handyman at the martial arts school, watching "Changfeng Fist"; Gang janitor, secretly learn "Blood Sword"; Immortal Sect's sweeping boy secretly recorded "Guiyuan Gong"... Get up from the mud, look up from the dust. From a corner of the town, to the distance of the rivers and lakes, and then to the top of the Immortal Gate. No one knew that he, a little unknown person, had already had a panoramic view of everything in the world. Many years later, the Demon Lord broke through the mountain gate, and the whole world was in panic. The nameless sweeper took one step forward, and his energy and blood were like a dragon, suppressing the world. Everyone is shocked: at the end of martial arts, can you really live forever? Lin Mu didn't say a word, but slowly closed the book in his hand, which was filled with countless dharma records.
