Tan Xuan, who was born in a modern poor family, has been trapped by the heavy pressure of life since childhood. He has been struggling at the bottom of society but has never been able to escape the shackles of poverty, and his life is miserable. By chance, he picked up a fragment that exuded a mysterious aura. Unexpectedly, this was the key to changing his destiny - the automatic training system awakened.
Starting from Duoduo's chance encounter with "Light Body Leap Kung Fu", Tan Xuan started a new life. The system is powerful, and its abilities of decomposition, insight, and time travel open up countless possibilities for him. He first solved difficult problems in modern times and accumulated strength and confidence; then he embarked on a journey across thousands of realms, traveling through ancient dynasties and experiencing the historical changes from the mystery of the Xia Dynasty to the vicissitudes of the Qing Dynasty; he ventured into the world of martial arts, experiencing the purity of common martial arts, the shock of middle martial arts, and the destructiveness of high martial arts; he went deep into the world of immortal cultivation, explored the territories of humans, elves, and other realms, and came into contact with the eight major ethnic groups of gods, demons, immortals, and demons, constantly breaking through the limits of cultivation.
When he was strong enough to gain a foothold in the world, Tan Xuan never forgot his original intention. He went to the orphanage to adopt children and taught them all he had learned and experienced in various worlds, determined to train them to become responsible and capable people to overcome the problems left from ancient times to the present. In the process of teaching children, Tan Xuan not only witnessed their growth, but also found a deeper meaning in life and gained an overflowing sense of happiness and accomplishment. This is a passionate cultivation legend about counterattack, exploration and inheritance.
