Shen Wuyuan, the good-for-nothing adopted son of the "Shen Family" of the martial arts family, has been scorned since childhood, but in fact he is the whetstone and living medicine guide for the family head's son "Shen Tianjiao". There is a "Martial Monument of Ten Thousand Worlds" hidden in the family's forbidden area, which can guide the afterimage trials of different martial arts worlds, but the family strictly prohibits people other than the core inheritors from touching it. In order to seek revenge, Shen Wuyuan took the risk of touching the martial arts monument in a desperate situation. With his strong martial arts understanding and unyielding will, he repeatedly "stealed" from the afterimages of the trials to learn the powerful martial arts from the other world that was abandoned by his family.
He used family resources to practice secretly, and acted both good and evil: he was cruel and ruthless to his enemies, but he had kind thoughts towards the low-level warriors who had helped him. Taking advantage of opportunities such as family competitions and exploration of secret realms, he was constantly "arranged" to challenge powerful enemies. In fact, he used otherworldly martial arts to defeat each of Shen Tianjiao's stepping stones, stirring up trouble in the family. As his strength grows, he gradually discovers that the secret of the martial monument is far beyond imagination - it is not connected to the "afterimage of the world", but to the real parallel martial arts world, and the Shen family has been extracting the martial arts origins of these worlds for generations.
In the process of stealing martial arts and fighting against his family, Shen Wuyuan attracted the attention of practitioners from other worlds, and was even involved in the struggle for the fate of martial arts in all realms. He must continue to make breakthroughs on this road that is both good and evil, not only to avenge the Shen family who dominates the sky with one hand, but also to get rid of his dual destiny as a "martial arts thief" and "family abandoned son", and fight his own way to the sky under the pressure of martial arts in the world and the huge shadow of his family.
